The development of DM type 2 can cause oxidative stress characterized by an imbalance between oxidants and antioxidants in the body Increased oxidative stress causes type 2 diabetes mellitus to require intake of exogenous antioxidants in large quantities to inhibit oxidative damage in the body. Bran can be defined as a functional food because it consists of 11.39% fiberand 28.7% antioxidants and the purple yam consists of anthocyanin which functions as an antioxidant. With abundant amount and low price, purple yam and bran can be used for analog rice as the effort to diversify functional food. The antioxidant’s activity of analog rice from purple yam and bran which is measured by using DPPH’s method is 12,963%. The rough fiber’s level on the analog rice from purple yam is 2.985%. The water amount of analog rice from purple yam and bran is 8.726%. Analog rice from purple yam and bran has the similar texture as the usual rice, tasted slightly sweet, light purple colored, and smelled like bran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=analog%20rice" title=" analog rice"> analog rice</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title=" functional food"> functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a> </p> <a href="https://publications.waset.org/abstracts/92581/functional-compounds-activity-of-analog-rice-based-on-purple-yam-and-bran-as-alternative-food-for-people-with-diabetes-mellitus-type-ii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92581.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">193</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Using Human-Digestive Simulator to Harbor Encapsulated Lactobacillus casei 01 along with Pasteurized-Purple-Rice Drinks for Examination of the Health-Promoting Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Srivilai%20Worametrachanon">Srivilai Worametrachanon</a>, <a href="https://publications.waset.org/abstracts/search?q=Arunee%20Apichartsrangkoon"> Arunee Apichartsrangkoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiranat%20Techarang"> Jiranat Techarang</a>, <a href="https://publications.waset.org/abstracts/search?q=Boonrak%20Phanchaisri"> Boonrak Phanchaisri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A human-digestive simulator consisted of four colon compartments, i.e., stomach, small intestine, proximal colon and distal colon used to harbor L. casei 01 plus either pasteurized ordinary-purple-rice drinks or germinated-purple-rice drinks.

L. casei 01 plus purple-rice drinks gave rise to significantly high formation (P ≤ 0.05) of short-chain-fatty acids (SCFA) of which highest acetic acid was found followed by propionic and butyric acids, while the germinated-rice drink showed the greatest impact. Moreover, the effect was more pronounced upon prolonged fermentation. In addition, the influence of treatments on colon microbes was also demonstrated. Accordingly, desirable bacteria including colon Lactobacilli and Bifidobacteria were significantly increased (P ≤ 0.05) in both colons in comparison with the control and the effect was more prominent after adding purple-rice drink. On the other hand, undesirable Clostridia and coliforms were apparently diminished by the influence of treatment conditions, in which both compartments exhibited similar results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-digestive%20simulator" title="human-digestive simulator">human-digestive simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=Lactobacillus%20casei%2001" title=" Lactobacillus casei 01"> Lactobacillus casei 01</a>, <a href="https://publications.waset.org/abstracts/search?q=Pasteurized-purple-rice%20drinks" title=" Pasteurized-purple-rice drinks"> Pasteurized-purple-rice drinks</a> </p> <a href="https://publications.waset.org/abstracts/14142/using-human-digestive-simulator-to-harbor-encapsulated-lactobacillus-casei-01-along-with-pasteurized-purple-rice-drinks-for-examination-of-the-health-promoting-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14142.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Differential Proteomics Expression in Purple Rice Supplemented Type 2 Diabetic Rats’ Skeletal Muscle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ei%20Ei%20Hlaing">Ei Ei Hlaing</a>, <a href="https://publications.waset.org/abstracts/search?q=Narissara%20Lailerd"> Narissara Lailerd</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittiruk%20Roytrakul"> Sittiruk Roytrakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Pichapat%20Piamrojanaphat"> Pichapat Piamrojanaphat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Type 2 diabetes is one of the most common metabolic diseases all over the world. The pathogenesis of type 2 diabetes is not the only dysfunction of pancreatic beta cells but also insulin resistance in muscle, liver and adipose tissue. High levels of circulating free fatty acids, an increased lipid content of muscle cells, impaired insulin-mediated glucose uptake and diminished mitochondrial functioning are pathophysiological hallmarks of diabetic skeletal muscles. Purple rice (Oryza sativa L. indica) has been shown to have antidiabetic effects. However, the underlying mechanism(s) of antidiabetic activity of purple rice is still unraveled. In this research, to explore in-depth cellular mechanism(s), proteomic profile of purple rice supplemented type 2 diabetic rats’ skeletal muscle were analyzed contract with non-supplemented rats. Diabetic rats were induced high-fat diet combined with streptozotocin injection. By using one- dimensional gel electrophoresis (1-DE) and LC-MS/MS quantitative proteomic method, we analyzed proteomic profiles in skeletal muscle of normal rats, normal rats with purple rice supplementation, type 2 diabetic rats, and type 2 diabetic rats with purple rice supplementation. Total 2676 polypeptide expressions were identified. Among them, 24 peptides were only expressed in type 2 diabetic rats, and 24 peptides were unique peptides in type 2 diabetic rats with purple rice supplementation. Acetyl CoA carboxylase 1 (ACACA) found as unique protein in type 2 diabetic rats which is the major enzyme in lipid synthesis and metabolism. Interestingly, DNA damage response protein, heterogeneous nuclear ribonucleoprotein K [Mus musculus] (Hnrnpk), was upregulated in type 2 diabetic rats’ skeletal muscle. Meanwhile, unique proteins of type 2 diabetic rats with purple rice supplementation (bone morphogenetic 7 protein preproprotein, BMP7; and forkhead box protein NX4, Foxn4) involved with muscle cells growth through the regulation of TGF-β/Smad signaling network. Moreover, BMP7 may effect on insulin signaling through the downstream signaling of protein kinase B (Akt) which acts in protein synthesis, glucose uptake, and glycogen synthesis. In conclusion, our study supports that type 2 diabetes impairs muscular lipid metabolism. In addition, purple rice might recover the muscle cells growth and insulin signaling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=proteomics" title="proteomics">proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=purple%20rice%20bran" title=" purple rice bran"> purple rice bran</a>, <a href="https://publications.waset.org/abstracts/search?q=skeletal%20muscle" title=" skeletal muscle"> skeletal muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20diabetic%20rats" title=" type 2 diabetic rats"> type 2 diabetic rats</a> </p> <a href="https://publications.waset.org/abstracts/58923/differential-proteomics-expression-in-purple-rice-supplemented-type-2-diabetic-rats-skeletal-muscle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58923.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Purple Sweet Potato Anthocyanin Attenuates the Fat-Induced Mortality in Drosophila Melanogaster</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lijun%20Wang">Lijun Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen-Yu%20Chen"> Zhen-Yu Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A high-fat diet induces the accumulation of lipid hydroperoxides, accelerates the ageing process and causes a greater mortality in Drosophila melanogaster. The purple sweet potato is rich in antioxidant anthocyanin. The present study was to examine if supplementation of purple sweet potato anthocyanin (PSPA) could reduce the mortality of fruit flies fed a high-fat diet. Results showed that the mean lifespan of fruit fly was shortened from 56 to 35 days in a dose-dependent manner when lard in the diet increased from 0% to 20%. PSPA supplementation attenuated partially the lard-induced mortality. The maximum lifespan and 50% survival time were 49 and 27 days for the 10% lard control flies, in contrast, they increased to 57 and 30 days in the PSPA-supplemented fruit flies. PSPA-supplemented diet significantly up-regulated the mRNA of superoxide dismutase, catalase and Rpn11, compared with those in the control lard diet. In addition, PSPA supplementation could restore the climbing ability of fruit flies fed a 10% lard diet. It was concluded that the lifespan-prolonging activity of PSPA was most likely mediated by modulating the genes of SOD, CAT and Rpn11. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=purple%20sweet%20potato" title="purple sweet potato">purple sweet potato</a>, <a href="https://publications.waset.org/abstracts/search?q=anthocyanin" title=" anthocyanin"> anthocyanin</a>, <a href="https://publications.waset.org/abstracts/search?q=high-fat%20diet" title=" high-fat diet"> high-fat diet</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/45155/purple-sweet-potato-anthocyanin-attenuates-the-fat-induced-mortality-in-drosophila-melanogaster" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> In vitro Antioxidant and DNA Protectant Activity of Different Skin Colored Eggplant (Solanum melongena)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20M.%20Somawathie">K.

The antioxidant activity was evaluated using the DPPH and ABTS free radical scavenging assay, ferric reducing antioxidant power (FRAP), ferric thiocyanate (FTC) and the egg yolk model. The effectiveness of eggplant extracts against radical induced DNA damage was also determined. There was a significant difference (p < 0.0001) between the skin color and antioxidant activity. TPC and FRAP values of eggplant extracts ranged from 48.67±0.27-61.11±0.26 (mg GAE/100 g fresh weight) and 4.19±0.11-7.46±0.26 (mmol of FeS04/g of fresh weight) respectively. MP displayed the highest percentage of DPPH radical scavenging activity while, DP demonstrated the strongest total antioxidant capacity. In the FTC and egg yolk model, DP and MP showed better antioxidant activity than PG and LP. All eggplant extracts showed potent antioxidant activity in retaining DNA against AAPH mediated radical damage. DP and MP demonstrated better antioxidant activity which may be attributed to the higher phenolic content since a positive correlation was observed between the TPC and the antioxidant parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solanum%20melongena" title="Solanum melongena">Solanum melongena</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20color" title=" skin color"> skin color</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20protection" title=" DNA protection"> DNA protection</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a> </p> <a href="https://publications.waset.org/abstracts/35657/in-vitro-antioxidant-and-dna-protectant-activity-of-different-skin-colored-eggplant-solanum-melongena" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35657.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">431</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Influence of Dairy Cows Food on Uncooked Pressed Dough Cheese "Edam" Quality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nougha%20Meriem">Nougha Meriem</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadouki%20Mohammed"> Sadouki Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cheese quality is an important manufacturing requirement.

In this study, we have seen the impact of distributing two different types of green feed (purple clover VS alfalfa), in a ration composed of oat hay, silage of corn and concentrated feed, in equal quantities, on resulting milk destined for an Edam manufacturing. It reveals that alfalfa allows a high production of milk, comparatively to purple clover. However, this latter allows a high quality of milk, in point of view physico-chemical properties, especially regarding proteins and fat yields, two essential factors affecting Edam quality. The obtained results indicated that milk allowed by purple clover shows a best physico-chemical quality beside alfalfa, for it use in Edam manufacturing according to the values recommended by standardized dairies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dairy%20cows" title="dairy cows">dairy cows</a>, <a href="https://publications.waset.org/abstracts/search?q=Edam" title=" Edam"> Edam</a>, <a href="https://publications.waset.org/abstracts/search?q=food" title=" food"> food</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a> </p> <a href="https://publications.waset.org/abstracts/23158/influence-of-dairy-cows-food-on-uncooked-pressed-dough-cheese-edam-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">321</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Using Medicinal Herbs in Designing Green Roofs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Javad%20Shakouri">Mohamad Javad Shakouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Behshad%20Riahipour"> Behshad Riahipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, the use of medicinal herbs in architecture and green space has a significant effect on the process of calming human and increases the reliability coefficient of design and design flexibility. The current research was conducted with the aim to design green roof and investigate the effect of medicinal herbs such as cress, leek, fenugreek, beet, sweet fennel, green basil, purple basil, and purslane on reducing the number of environmental pollutants (copper, zinc, and cadmium). Finally, the weight of the dry plant and the concentration of elements zinc, lead, and cadmium in the herbs was measured. According to the results, the maximum dry weight (88.10 and 73.79 g) was obtained in beet and purslane respectively and the minimum dry weight (24.12 and 25.21) was obtained in purple basil, and green basil respectively. The maximum amount of element zinc (235 and 213 mg/kg) and the maximum amount of lead (143 mg/kg) were seen in sweet fennel and purple basil. In addition, the maximum amount of cadmium (13 mg/kg) was seen in sweet fennel and purple basil and the minimum amount of lead and cadmium (78 and 7 mg/kg) was seen in green basil, and the minimum amount of zinc (110 mg/kg) was seen in leek. On the other hand, the absorption amount of element lead in the herbs beet and purslane was the same and both absorbed 123 mg/kg lead. Environmentally, if green roofs are implemented extensively and in wide dimensions in urban spaces, they will purify and reduce pollution significantly by absorbing carbon dioxide and producing oxygen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medicinal%20herbs" title="medicinal herbs">medicinal herbs</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20space" title=" green space"> green space</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20roof" title=" green roof"> green roof</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=lead" title=" lead"> lead</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20basil" title=" green basil"> green basil</a> </p> <a href="https://publications.waset.org/abstracts/96751/using-medicinal-herbs-in-designing-green-roofs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96751.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Colour Characteristics of Dried Cocoa Using Shallow Box Fermentation Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khairul%20Bariah%20Sulaiman">Khairul Bariah Sulaiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Tajul%20Aris%20Yang"> Tajul Aris Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fermentation is well known as an essential process in cocoa beans. Besides to develop the precursor of cocoa flavour, it also induce the colour changes in the beans.The fermentation process is reported to be influenced by duration of pod storage and fermentation. Therefore, this study was conducted to evaluate colour of Malaysian cocoa beans and how the pods storage and fermentation duration using shallow box technique will effect on it characteristics. There are two factors being studied ie duration of cocoa pod storage (0, 2, 4, and 6 days) and duration of cocoa fermentation (0, 1, 2, 3, 4 and 5 days). The experiment is arranged in 4 x 6 factorial design with 24 treatments and arrangement is in a Completely Randomised Design (CRD). The produced beans is inspected for colour changes under artificial light during cut test and divided into four groups of colour namely fully brown, purple brown, fully purple and slaty. Cut tests indicated that cocoa beans which are directly dried without undergone fermentation has the highest slaty percentage. However, application of pods storage before fermentation process is found to decrease the slaty percentage. In contrast, the percentages of fully brown beans start to dominate after two days of fermentation, especially from four and six days of pods storage batch. Whereas, almost all batch have percentage of fully purple less than 20%. Interestingly, the percentage of purple brown beans are scattered in the entire beans batch regardless any specific trend. Meanwhile, statistical analysis using General Linear Model showed that the pods storage has a significant effect on the colour characteristic of the Malaysian dried beans compared to fermentation duration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoa%20beans" title="cocoa beans">cocoa beans</a>, <a href="https://publications.waset.org/abstracts/search?q=colour" title=" colour"> colour</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=shallow%20box" title=" shallow box"> shallow box</a> </p> <a href="https://publications.waset.org/abstracts/34006/colour-characteristics-of-dried-cocoa-using-shallow-box-fermentation-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34006.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">491</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Antioxidant Face Mask from Purple Sweet Potato (Ipomea Batatas) with Oleum Cytrus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lilis%20Kistriyani">Lilis Kistriyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Dine%20Olisvia"> Dine Olisvia</a>, <a href="https://publications.waset.org/abstracts/search?q=Lutfa%20Rahmawati"> Lutfa Rahmawati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Facial mask is an important part of every beauty treatment because it will give a smooth and gentle effect on the face. This research is done to make edible film that will be applied for face mask. The main ingredient in making this edible film is purple sweet potato powder with the addition of glycerol as plasticizer. One of the ingredients in purple sweet potato is a flavonoid compound. The purpose of this study was to determine the effect of increasing the amount of glycerol to flavonoids release and the effect on the physical properties and biological properties of edible film produced. The stages of this research are the making of edible film, then perform some analysis, among others, spectrophotometer UV-vis analysis to find out how many flavonoids can be released into facial skin, tensile strength and elongation of break analysis, biodegradability analysis, and microbiological analysis. The variation of edible film is the volume of glycerol that is 1 ml, 2 ml, 3 ml. The results of spectrophotometer UV-vis analysis showed that the most flavonoid release concentration is 20.33 ppm in the 2 ml glycerol variation. The best tensile strength value is 8,502 N, and the greatest elongation of break value is 14% in 1 ml glycerol variation. In the biodegradability test, the more volume of glycerol added the faster the edible film is degraded. The results of microbiological analysis showed that purple sweet potato extract has the ability to inhibit the growth of Propionibacterium acnes seen in the presence of inhibiting zone which is 18.9 mm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=face%20mask" title="face mask">face mask</a>, <a href="https://publications.waset.org/abstracts/search?q=edible%20film" title=" edible film"> edible film</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticizer" title=" plasticizer"> plasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid" title=" flavonoid"> flavonoid</a> </p> <a href="https://publications.waset.org/abstracts/89490/antioxidant-face-mask-from-purple-sweet-potato-ipomea-batatas-with-oleum-cytrus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Pharmacological Activities and Potential Uses of Cyperus Rotundus: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arslan%20Masood%20Pirzada">Arslan Masood Pirzada</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem"> Muhammad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Haider%20Ali"> Hafiz Haider Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Latif"> Muhammad Latif</a>, <a href="https://publications.waset.org/abstracts/search?q=Aown%20Sammar%20Raza"> Aown Sammar Raza</a>, <a href="https://publications.waset.org/abstracts/search?q=Asad%20Hussain%20Bukhari"> Asad Hussain Bukhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saqib"> Muhammad Saqib</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ijaz"> Muhammad Ijaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cyperus rotundus (Cyperaceae), a medicinal herb, is being traditionally used as a home remedy for the treatment of various clinical conditions like diarrhea, diabetic, pyretic, inflammation, malaria, and for treating stomach and bowel disorders. Its current status is one of the most widespread, troublesome, and economically damaging agronomic weeds, growing wildly in various tropical and sub-tropical regions of the world. Tuber and rhizomes of Cyperus rotundus possess a higher concentration of active ingredients in the form of essential oils, phenolic acids, ascorbic acids and flavonoids, responsible for its remedial properties. Exploitation of any medicinal plant application depends on the crucial and comprehensive information about the therapeutic potential of a plant. Researchers have evaluated and characterized the significance of Cyperus rotundus as an anti-androgenic, anti-bacterial, anti-cancerous, anti-convulsant, anti-diabetic, anti-diarrheal, anti-genotoxic, anti-inflammatory, anti-lipidemic, anti-malarial, anti-mutagenic, anti-obesity, anti-oxidant, anti-uropathogenic, hepato-, cardio-, neuroprotective, and nootropic agent. This paper comprises a broad review to summarize the current state of knowledge about chemical constituents, potential economic uses and therapeutic aspects of Cyperus rotundus that will aid in the development of bioethanol and modern herbal medicine through latest technologies that will promote the ability of this plant in the cure of many clinical disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=purple%20nutsedge" title="purple nutsedge">purple nutsedge</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20composition" title=" chemical composition"> chemical composition</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20uses" title=" economic uses"> economic uses</a>, <a href="https://publications.waset.org/abstracts/search?q=therapeutic%20values" title=" therapeutic values"> therapeutic values</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20directions" title=" future directions"> future directions</a> </p> <a href="https://publications.waset.org/abstracts/23922/pharmacological-activities-and-potential-uses-of-cyperus-rotundus-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23922.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">513</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Antibacterial and Antioxidant Capacity of Fabric Treated with Purple-Fleshed Sweet Potato Extract</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyung%20Hwa%20Hong">Kyung Hwa Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunmi%20Koh"> Eunmi Koh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wool and cotton fabrics are pretreated by a tannic acid aqueous solution to increase their dyeability and then dyed by Purple-Fleshed Sweet Potato (PSP) extract. The dyed fabrics are then investigated by various analysis techniques. The results revealed that wool and cotton fabrics can be dyed bluish red through the pretreatment and dyeing process. Both wool and cotton fabrics only pretreated with tannic acid display decreased L* value but no significant changes in a* and b* values as the concentration of tannic acid increases. And, as expected, the pretreated fabrics are even darker and show a richer purple color after the dyeing process with the PSP extract. With regard to the colorfastness of wool and cotton fabrics dyed by PSP extract in cleaning circumstances, such as dry-cleaning (for wool) and washing (for cotton), the wool and cotton fabrics had a 4.0 and 4.0 grade of colorfastness to dry-cleaning and washing, respectively. However, they both exhibited significantly inferior colorfastness to light (grade of 1.5). Thus, it was found that there is still a need for improvement with regard to color fastness, particularly against light. On the other hand, the wool and cotton fabrics also showed antibacterial and antioxidant characteristics. In addition, both the wool and cotton fabrics showed potential antibacterial ability (>99%) against Staphylococcus aureus; however, they showed somewhat insufficient antibacterial ability (60.8% for wool and 94.8% for cotton) against Klebsiella pneumoniae. Also, their antioxidant abilities increased up to ca. 90% with an increase in the tannic acid concentration (up to 0.5%). However, after the dyeing process, the antibacterial and antioxidant ability tended to decrease. This is assumed to have occurred because functional moieties such as phenolic acids were detached from the pretreated fabrics into the hot water (the dyeing solution) during the dyeing process. Therefore, further study would be necessary to derive the optimum treatment and dyeing conditions so as to maximize the coloring effect and functionalities of the fabrics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title="antibacterial activity">antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=purple-fleshed%20sweet%20potato" title=" purple-fleshed sweet potato"> purple-fleshed sweet potato</a>, <a href="https://publications.waset.org/abstracts/search?q=fabrics" title=" fabrics"> fabrics</a> </p> <a href="https://publications.waset.org/abstracts/61404/antibacterial-and-antioxidant-capacity-of-fabric-treated-with-purple-fleshed-sweet-potato-extract" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61404.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Purple Spots on Historical Parchments: Confirming the Microbial Succession at the Basis of Biodeterioration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Perini">N.

Migliore</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The preservation of cultural heritage is one of the major challenges of today’s society, because of the fundamental right of future generations to inherit it as the continuity with their historical and cultural identity. Parchments, consisting of a semi-solid matrix of collagen produced from animal skin (i.e., sheep or goats), are a significant part of the cultural heritage, being used as writing material for many centuries. Due to their animal origin, parchments easily undergo biodeterioration. The most common biological damage is characterized by isolated or coalescent purple spots that often leads to the detachment of the superficial layer and the loss of the written historical content of the document. Although many parchments with the same biodegradative features were analyzed, no common causative agent has been found so far. Very recently, a study was performed on a purple-damaged parchment roll dated back 1244 A.D, the A.A. Arm. I-XVIII 3328, belonging to the oldest collection of the Vatican Secret Archive (Fondo 'Archivum Arcis'), by comparing uncolored undamaged and purple damaged areas of the same document. As a whole, the study gave interesting results to hypothesize a model of biodeterioration, consisting of a microbial succession acting in two main phases: the first one, common to all the damaged parchments, is characterized by halophilic and halotolerant bacteria fostered by the salty environment within the parchment maybe induced by bringing of the hides; the second one, changing with the individual history of each parchment, determines the identity of its colonizers. The design of this model was pivotal to this study, performed by different labs of the Tor Vergata University (Rome, Italy), in collaboration with the Vatican Secret Archive. Three documents, belonging to a collection of dramatically damaged parchments archived as 'Faldone Patrizi A 19' (dated back XVII century A.D.), were analyzed through a multidisciplinary approach, including three updated technologies: (i) Next Generation Sequencing (NGS, Illumina) to describe the microbial communities colonizing the damaged and undamaged areas, (ii) RAMAN spectroscopy to analyze the purple pigments, (iii) Light Transmitted Analysis (LTA) to evaluate the kind and entity of the damage to native collagen. The metagenomic analysis obtained from NGS revealed DNA sequences belonging to Halobacterium salinarum mainly in the undamaged areas. RAMAN spectroscopy detected pigments within the purple spots, mainly bacteriorhodopsine/rhodopsin-like pigments, a purple transmembrane protein containing retinal and present in Halobacteria. The LTA technique revealed extremely damaged collagen structures in both damaged and undamaged areas of the parchments. In the light of these data, the study represents a first confirmation of the microbial succession model described above. The demonstration of this model is pivotal to start any possible new restoration strategy to bring back historical parchments to their original beauty, but also to open opportunities for intervention on a huge amount of documents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodeterioration" title="biodeterioration">biodeterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=parchments" title=" parchments"> parchments</a>, <a href="https://publications.waset.org/abstracts/search?q=purple%20spots" title=" purple spots"> purple spots</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20succession" title=" ecological succession"> ecological succession</a> </p> <a href="https://publications.waset.org/abstracts/82803/purple-spots-on-historical-parchments-confirming-the-microbial-succession-at-the-basis-of-biodeterioration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82803.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">171</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> The Effect of Probiotics Lactococcus plantarum and Prebiotic Purple Sweet Potato (Ipomoea batatas sp.) on Performance and Cholesterol Meat of Local Ducks </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Husmaini">Husmaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Rijal%20Zein"> Rijal Zein</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulkarnain"> Zulkarnain</a>, <a href="https://publications.waset.org/abstracts/search?q=Marlito%20Latifa"> Marlito Latifa</a>, <a href="https://publications.waset.org/abstracts/search?q=Syahrul%20E.%20Rambee"> Syahrul E.

One hundred two weeks old male local ducks placed in 4 treatment doses for ten weeks. The treatments were the dosage of PPSP, i.e., 0, 1, 2 and 3 grams of PPSP/bird/week. One gram PPSP contains 1.3 x 108 colony form unit. Data were analyzed statistically using SPSS and DMRT. The results showed that PPSP administration in local ducks did not affect intestinal villi height and fed consumption (P > 0.05), but highly significant (P < 0.01) increasing duodenum thickness, body weight, carcass yield and reducing both feed conversion and cholesterol meat content. The difference in PPSP dosage (1.2 and 3 grams) had the same effect on body weight gain. However, it has a different impact on feed conversion and meat cholesterol levels. The higher the PPSP dose given, the lower the feed conversion and meat cholesterol level. This study has shown that administration of PPSP can improve performance and reduce cholesterol levels of local duck meat. Giving PPSP as much as 3 grams per bird every week has provided the best results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cholesterol" title="cholesterol">cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20duck" title=" local duck"> local duck</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotics" title=" probiotics"> probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=purple%20sweet%20potato" title=" purple sweet potato"> purple sweet potato</a> </p> <a href="https://publications.waset.org/abstracts/105670/the-effect-of-probiotics-lactococcus-plantarum-and-prebiotic-purple-sweet-potato-ipomoea-batatas-sp-on-performance-and-cholesterol-meat-of-local-ducks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105670.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Determination of Performances of Some Mulberry (Morus spp.) Species Selected from Different Places of Turkey under Kahramanmaras Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muruvvet%20Ilgin">Muruvvet Ilgin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilknur%20Agca"> Ilknur Agca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Common mulberry (Morus levigate Wall.) and purple mulberry (Morus rubra L.) species which were selected from different regions of Turkey were used as material in order to determine their performance.

Wetland rice is grown under flooded condition from transplanting until the mutuality, while upland rice is naturally grown under well-drained soil known as aerobic cultivations. Both ecotypes can be grown and adapted to the reverse systems but little is known on its responses of grain yield and qualities between the 2 ecotypes. This study evaluated responses of grain yield as well as anthocyanin and antioxidant capacity between the wetland and upland purple rice genotypes grown in the submerged and aerobic conditions. A factorial arrangement in a randomized complete block design (RCBD) with two factors of rice genotype and water condition were carried out in three replications. The two wetland genotypes (Kum Doi Saket: KDK and Kum Phayao: KPY) and two upland genotypes (Kum Hom CMU: KHCMU and Pieisu1: PES1) were used in this study by growing under submerged and aerobic conditions. Grain yield was affected by the interaction between water condition and rice genotype. The wetland genotypes, KDK and KPY grown in the submerged condition produced about 2.7 and 0.8 times higher yield than in the aerobic condition, respectively. The 0.4 times higher grain yield of upland genotype (PES1) was found in the submerged condition than in the aerobic condition, but no significant differences in KHCMU. In the submerged condition, all genotypes produced higher yield components of tiller number, panicle number and percent filled grain than in the aerobic condition by 24% and 32% and 11%, respectively. The thousand grain weight and spikelet number were affected by water condition differently among genotypes. The wetland genotypes, KDK and KPY, and upland genotype, PES1, grown in the submerged condition produced about 19-22% higher grain weight than in the aerobic condition. The similar effect was found in spikelet number which the submerged condition of wetland genotypes, KDK and KPY, and the upland genotype, KHCMU, had about 28-30% higher than the aerobic condition. In contrast, the anthocyanin concentration and antioxidant capacity were affected by both the water condition and genotype. Rice grain grown in the aerobic condition had about 0.9 and 2.6 times higher anthocyanin concentration than in the submerged condition was found in the wetland rice, KDK and upland rice, KHCMU, respectively. Similarly, the antioxidant capacity of wetland rice, KDK and upland rice, KHCMU were 0.5 and 0.6 times higher in aerobic condition than in the submerged condition. There was a negative correlation between grain yield and anthocyanin concentration in wetland genotype KDK and upland genotype KHCMU, but it was not found in the other genotypes. This study indicating that some rice genotype can be adapted in the reverse ecosystem in both grain yield and quality, especially in the wetland genotype KPY and upland genotype PES1. To maximize grain yield and quality of purple rice, proper water management condition is require with a key consideration on difference responses among genotypes. Increasing number of rice genotypes in both ecotypes is needed to confirm their responses on water management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=purple%20rice" title="purple rice">purple rice</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20condition" title=" water condition"> water condition</a>, <a href="https://publications.waset.org/abstracts/search?q=anthocyanin" title=" anthocyanin"> anthocyanin</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20yield" title=" grain yield"> grain yield</a> </p> <a href="https://publications.waset.org/abstracts/93288/responses-of-grain-yield-anthocyanin-and-antioxidant-capacity-to-water-condition-in-wetland-and-upland-purple-rice-genotypes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Bio-Nano Mask: Antivirus and Antimicrobial Mouth Mask Coating with Nano-TiO2 and Anthocyanin Utilization as an Effective Solution of High ARI Patients in Riau</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Annisa%20Ulfah%20Pristya">Annisa Ulfah Pristya</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Setiawan"> Andi Setiawan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia placed in sixth rank total Acute Respiratory Infection (ARI) patient in the world and Riau as one of the province with the highest number of people with respiratory infection in Indonesia reached 37 thousand people.

The latter one is produced in dark-purple globose ‘cleistothecia’ which are surrounded by Hülle cells. The species has a homothallic (self fertile) sexual breeding system. Given the extra metabolic costs associated with sexual compared to asexual reproduction it would be predicted that ascospore production would confer evolutionary benefits. However, due to the homothallic breeding system there is very rarely any increased genetic variation in ascospore offspring and traditionally conidia and ascospores are considered to be equally environmental resistant. We therefore examined in detail whether conidia and ascospores might exhibit as yet undetected differences in spore viability when subjected to certain environmental stressors. Spores from two strains of A. nidulans (comprising wild-type and KU mutants) were exposed to various levels of temperature (50-70°C for 30 min) and UV (350 nm for 10-60 min) stress. Results of experiments will be presented, including comparison of ‘D’ (decimal point reduction) values of conidia versus ascospores of A. nidulans. We detected that under certain exposure levels ascospores have significantly increased resistance compared to conidia. The increased environmental resistance of ascospores might be a key factor explaining the persistence of sexuality in this homothallic species, and reasons for differential survival are suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aspergillus%20nidulans" title="Aspergillus nidulans">Aspergillus nidulans</a>, <a href="https://publications.waset.org/abstracts/search?q=asexual%20reproduction" title=" asexual reproduction"> asexual reproduction</a>, <a href="https://publications.waset.org/abstracts/search?q=conidia" title=" conidia"> conidia</a>, <a href="https://publications.waset.org/abstracts/search?q=ascospores" title=" ascospores"> ascospores</a>, <a href="https://publications.waset.org/abstracts/search?q=cleistothecia" title=" cleistothecia"> cleistothecia</a>, <a href="https://publications.waset.org/abstracts/search?q=d-value" title=" d-value"> d-value</a> </p> <a href="https://publications.waset.org/abstracts/12806/advantages-of-sexual-reproduction-in-aspergillus-nidulans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12806.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Study on the Relative Factors of Introducing Table Vinegar in Reducing Urinary Tract Infection in Patients with Long-Term Indwelling Catheter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Ju%20Hsieh">Yu-Ju Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin-Hung%20Lin"> Lin-Hung Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Hui%20Chang"> Wen-Hui Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was designed as an interventional research and intended to validate whether the introduction of drinking vinegar every day can reduce and even prevent urinary tract infection in Taiwan home stayed disabilities who using indwelling catheter. The data was collected from the subjects who have received home care case at northern Taiwan, according to the questionnaire and a medical records retroactive methodology, the subjects were informed and consent to drink 15ml of table vinegar in a daily diet, and through routine urine testing and culture study. Home care nurses would assist collecting urine at the point of before and after a meal from total 35 studied subjects per month, and total collected 4 times for testing. The results showed that when the average age of study subjects was 65.46 years and catheter indwelling time was 15 years, drinking table vinegar could inhibit the activity of E. coli O157: H7 and reduce its breeding. Before drinking table vinegar daily, the subjects’ urine pH value was 7.0-8.0, and the average was 7.5, and the urine PH value dropped to 6.5 after drinking table vinegar for a month.

The primary objective of the study is to unravel the psychological, emotional, and social factors that drive individuals, akin to Celie in Alice Walker’s ‘The Color Purple’, to contemplate and undergo changes in their sexual orientation following the trauma of sexual violence. Through an analytical and qualitative approach, the study employs in-depth textual and thematic analyses to scrutinize the complex interplay between sexual orientation and violence within the selected text. Through a close examination of Celie’s journey and experiences, the study reveals that her decision to switch sexual orientation arises from a desire for a more favorable and benevolent relationship driven by the absence of safety and refuge in her previous relationships. By establishing this bond between sexual orientation and violence, the research underscores how sexual violence can lead individuals to opt for a change in their sexual orientation. The findings highlight Celie’s transformation as a means to seek solace and security, thus concluding that sexual violence can prompt individuals to alter their sexual orientation. The ensuing discussion explores the implications of these findings, encompassing psychological, emotional, and social consequences, as well as the societal and cultural factors influencing the perception of sexual orientation. Additionally, it sheds light on the challenges and stigma faced by those who undergo such transformations. By comprehending the complex relationship between sexual violence and the decision to change sexual orientation, as exemplified by Celie in ‘The Color Purple’, a deeper understanding of the experiences of survivors who seek a safe haven through altering their sexual orientation can be attained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexual%20violence" title="sexual violence">sexual violence</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20orientation" title=" sexual orientation"> sexual orientation</a>, <a href="https://publications.waset.org/abstracts/search?q=refuge" title=" refuge"> refuge</a>, <a href="https://publications.waset.org/abstracts/search?q=transition" title=" transition"> transition</a> </p> <a href="https://publications.waset.org/abstracts/178819/in-search-of-a-safe-haven-sexual-violence-leading-to-a-change-of-sexual-orientation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178819.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Comparative Analysis of the Antioxidant Capacities of Pre-Germinated and Germinated Pigmented Rice (Oryza sativa L.

Due to the growing number of demand as a potential functional food and nutraceutical source and the increasing awareness of people towards healthy diet and good quality of living, more researches dwell upon the development of new rice cultivars for population consumption. However, studies on the antioxidant capacities of newly developed rice were limited as well as the effects of germination in these rice cultivars. Therefore, this study aimed to focus on analysis of the antioxidant potential of pre-germinated and germinated pigmented rice cultivars in South Korea such as purple cultivar Superjami (SJ) and red cultivar Super hongmi (SH) in comparison with the non-pigmented Normal Brown (NB) Rice. The powdered rice grain samples were extracted with 80% methanol and their antioxidant activities were determined. The Results showed that pre-germinated pigmented rice cultivars have higher Fe2+ Chelating Ability (Fe2+), Reducing Power (RP), 2,2´-azinobis[3-ethylbenzthiazoline]-6-sulfonic acid (ABTS) radical scavenging and Superoxide Dismutase activity than the control NB rice. Moreover, it is revealed that germination process induced a significant increased in the antioxidant activities of all the rice samples regardless of their strains. Purple rice SJ showed greater Fe2+ (88.82 + 0.53%), RP (0.82 + 0.01) , ABTS (143.63 + 2.38 mg VCEAC/100 g) and SOD (59.31 + 0.48%) activities than the red grain SH and the control NB having the lowest antioxidant potential among the three (3) rice samples examined. The Effective concentration at 50% (EC50) of 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) and Hydroxyradical (-OH) Scavenging activity for the rice samples were also obtained. SJ showed lower EC50 in terms of its DPPH (3.81 + 0.15 mg/mL) and –OH (5.19 + 0.08 mg/mL) radical scavenging activities than the red grain SH and control NB rice indicating that at lower concentrations, it can readily exhibit antioxidant effects against reactive oxygen species (ROS). These results clearly suggest the higher antioxidant potential of pigmented rice varieties as compared with the widely consumed NB rice. Also, it is revealed in the study that even at lower concentrations, pigmented rice varieties can exhibit their antioxidant activities. Germination process further enhanced the antioxidant capacities of the rice samples regardless of their types. With these results at hand, these new rice varieties can be further developed as a good source of bio functional elements that can help alleviate the growing number of cases of metabolic disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20capacity" title="antioxidant capacity">antioxidant capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=germinated%20rice" title=" germinated rice"> germinated rice</a>, <a href="https://publications.waset.org/abstracts/search?q=pigmented%20rice" title=" pigmented rice"> pigmented rice</a>, <a href="https://publications.waset.org/abstracts/search?q=super%20hongmi" title=" super hongmi"> super hongmi</a>, <a href="https://publications.waset.org/abstracts/search?q=superjami" title=" superjami"> superjami</a> </p> <a href="https://publications.waset.org/abstracts/31157/comparative-analysis-of-the-antioxidant-capacities-of-pre-germinated-and-germinated-pigmented-rice-oryza-sativa-l-cv-superjami-and-superhongmi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Antioxidant Activity of Selected Medicinal Plants Used in Folk Medicine in Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salmin%20Alshalmani">Salmin Alshalmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghazall%20M%20Benhusein"> Ghazall M Benhusein</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebtisam%20Alhadi%20Absomaha"> Ebtisam Alhadi Absomaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Marwa%20I.%20Meshri"> Marwa I.

Many plant species from this family are used in science and medicine. Some researchers believe that the medicinal properties of these plants are caused by the action on the organism of the individual components (camphor, menthol, thymol, eugenol, phenols, flavonoids, alcohols, and their derivatives) or the entire complex of essential oils. Biologically active substances (BAS), isolated from these medicinal plants can be an effective supplement in the complex treatment of infectious diseases. The substances of the phenolic group such as flavonoids and phenolic acids; and also alkaloids included in the component composition of the plants from the family Lamiaceae Lindl. present the scientific and practical interest for future investigations of their biological activity and development of medicinal products. The research objects are the species from the family Lamiaceae Lindl., cultivated in the North-Kazakhstan region. In this abstract, we present the results of the investigation of polyphenolic complex (flavonoids and phenolic acids) and alkaloids in aqueous and ethanol extracts. Investigation of the qualitative composition of flavonoids in the aqueous extracts showed that the species Monarda Diana contains flavone, Dracocephalum moldavica contains rutin, Ocimum basilicum (purple form) contains both ruin and quercetin. Biochemical analysis revealed that the ethanol extract of Monarda Diana has phenolic acids, similar to protocatechuic and benzoic acids by their chromatographic characteristics. But the aqueous extract contains four phenolic acids, one of which is an analogue of gentisic acid; and the other three are not identified yet. The phenolic acids such as benzoic and gentisic acids identified in ethanol extracts of species Ocimum basilicum (purple form) and Satureja hortensis, correspondingly. But the same phenolic acids did not appear in aqueous extracts. The phenolic acids were not determined neither in the ethanol or aqueous extracts of species Dracocephalum moldavica. The biochemical analysis did not reveal the content of alkaloids in aqueous extracts of investigated plants. However, the alkaloids in the amount of 5-13 components were identified in the ethanolic extracts of plants by the qualitative reactions.

Staphylococcus aureus, Listeria monocytogenes and Salmonella enteritis are important human pathogens. Diagnostic assays for bacterial culture and identification are time consuming and laborious. There is an urgent need to develop rapid, sensitive, and inexpensive diagnostic tests. In this study, a gold nanoprobe strategy developed and relies on the colorimetric differentiation of specific DNA sequences based approach on differential aggregation profiles in the presence or absence of specific target hybridization. Method: Gold nanoparticles (AuNPs) were purchased from Nanopartz. They were conjugated with thiolated oligonucleotides specific for the femA gene for the identification of members of Staphylococcus aureus, the mecA gene for the differentiation of Staphylococcus aureus and MRSA Staphylococcus aureus, hly gene encoding the pore-forming cytolysin listeriolysin for the identification of Listeria monocytogenes and the invA sequence for the identification of Salmonella enteritis. DNA isolation from Staphylococcus aureus Listeria monocytogenes and Salmonella enteritis cultures was performed using the commercial kit Nucleospin Tissue (Macherey Nagel). Specifically 20μl of DNA was diluted in 10mMPBS (pH5). After the denaturation of 10min, 20μl of AuNPs was added followed by the annealing step at 58oC. The presence of a complementary target prevents aggregation with the addition of acid and the solution remains pink, whereas in the opposite event it turns to purple. The color could be detected visually and it was confirmed with an absorption spectrum. Results: Specifically, 0.123 μg/μl DNA of St. aureus, L.monocytogenes and Salmonella enteritis was serially diluted from 1:10 to 1:100. Blanks containing PBS buffer instead of DNA were used. The application of the proposed method on isolated bacteria produced positive results with all the species of St. aureus and L. monocytogenes and Salmonella enteritis using the femA, mecA, hly and invA genes respectively. The minimum detection limit of the assay was defined at 0.2 ng/μL of DNA. Below of 0.2 ng/μL of bacterial DNA the solution turned purple after addition of HCl, defining the minimum detection limit of the assay. None of the blank samples was positive. The specificity was 100%. The application of the proposed method produced exactly the same results every time (n = 4) the evaluation was repeated (100% repeatability) using the femA, hly and invA genes. Using the gene mecA for the differentiation of Staphylococcus aureus and MRSA Staphylococcus aureus the method had a repeatability 50%. Conclusion: The proposed method could be used as a highly specific and sensitive screening tool for the detection and differentiation of Staphylococcus aureus Listeria monocytogenes and Salmonella enteritis. The use AuNPs for the colorimetric detection of DNA targets represents an inexpensive and easy-to-perform alternative to common molecular assays. The technology described here, may develop into a platform that could accommodate detection of many bacterial species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20nanoparticles" title="gold nanoparticles">gold nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=pathogens" title=" pathogens"> pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title=" nanotechnology"> nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a> </p> <a href="https://publications.waset.org/abstracts/15694/gold-nanoprobes-assay-for-the-identification-of-foodborn-pathogens-such-as-staphylococcus-aureus-listeria-monocytogenes-and-salmonella-enteritis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15694.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">341</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Characterisation, Extraction of Secondary Metabolite from Perilla frutescens for Therapeutic Additives: A Phytogenic Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20M.%20Vishal">B.

Ranging from the cost-effectiveness to the ease of synthesis, the process is simplified in the best possible way and is one of the most explored topics. This study of extracting secondary metabolites from Perilla frutescens and using them for therapeutic additives has its own significance. Unlike the other researches that have been done so far, this study aims to synthesize Silver nano particles from Perilla frutescens using three available forms of the plant: leaves, seed, and commercial leaf extract powder. Perilla frutescens, commonly known as 'Beefsteak Plant', is a perennial plant and belongs to the mint family. The plant has two varieties classed within itself. They are frutescens crispa and frutescens frutescens. The species, frutescens crispa (commonly known as 'Shisho' in Japanese), is generally used for edible purposes. Its leaves occur in two forms, varying on the colors. It is found in two different colors of red with purple streaks and green with crinkly pattern on it. This species is aromatic due to the presence of two major compounds: polyphenols and perillaldehyde. The red (purple streak) variety of this plant is due to the presence of a pigment, Perilla anthocyanin. The species, frutescens frutescens (commonly known as 'Egoma' in Japanese), is the main source for perilla oil. This species is also aromatic, but in this case, the major compound which gives the aroma is Perilla ketone or egoma ketone. Shisho grows short as compared with Wild Sesame and both produce seeds. The seeds of Wild Sesame are large and soft whereas that of Shisho is small and hard. The seeds have a large proportion of lipids, ranging about 38-45 percent. Excluding those, the seeds have a large quantity of Omega-3 fatty acids, linoleic acid, and an Omega-6 fatty acid. Other than these, Perilla leaf extract has gold and silver nano particles in it. The yield comparison in all the cases have been done, and the process’ optimal conditions were modified, keeping in mind the efficiencies. The characterization of secondary metabolites includes GC-MS and FTIR which can be used to identify the components of purpose that actually helps in synthesizing silver nano particles. The analysis of silver was done through a series of characterization tests that include XRD, UV-Vis, EDAX, and SEM. After the synthesis, for being used as therapeutic additives, the toxin analysis was done, and the results were tabulated. The synthesis of silver nano particles was done in a series of multiple cycles of extraction from leaves, seeds and commercially purchased leaf extract. The yield and efficiency comparison were done to bring out the best and the cheapest possible way of synthesizing silver nano particles using Perilla frutescens. The synthesized nano particles can be used in therapeutic drugs, which has a wide range of application from burn treatment to cancer treatment. This will, in turn, replace the traditional processes of synthesizing nano particles, as this method will prove effective in terms of cost and the environmental implications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20synthesis" title=" green synthesis"> green synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=Perilla%20frutescens" title=" Perilla frutescens"> Perilla frutescens</a>, <a href="https://publications.waset.org/abstracts/search?q=characterisation" title=" characterisation"> characterisation</a>, <a href="https://publications.waset.org/abstracts/search?q=toxin%20analysis" title=" toxin analysis"> toxin analysis</a> </p> <a href="https://publications.waset.org/abstracts/84400/characterisation-extraction-of-secondary-metabolite-from-perilla-frutescens-for-therapeutic-additives-a-phytogenic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84400.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">233</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Functionalizing Gold Nanostars with Ninhydrin as Vehicle Molecule for Biomedical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Swati%20Mishra">Swati Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been an explosion in Gold NanoParticle (GNP) research, with a rapid increase in publications in diverse fields, including imaging, bioengineering, and molecular biology. GNPs exhibit unique physicochemical properties, including surface plasmon resonance (SPR) and bind amine and thiol groups, allowing surface modification and use in biomedical applications. Nanoparticle functionalization is the subject of intense research at present, with rapid progress being made towards developing biocompatible, multi-functional particles. In the present study, the photochemical method has been done to functionalize various-shaped GNPs like nanostars by the molecules like ninhydrin. Ninhydrin is bactericidal, virucidal, fungicidal, antigen-antibody reactive, and used in fingerprint technology in forensics. The GNPs functionalized with ninhydrin efficiently will bind to the amino acids on the target protein, which is of eminent importance during the pandemic, especially where long-term treatments of COVID- 19 bring many side effects of the drugs. The photochemical method is adopted as it provides low thermal load, selective reactivity, selective activation, and controlled radiation in time, space, and energy. The GNPs exhibit their characteristic spectrum, but a distinctly blue or redshift in the peak will be observed after UV irradiation, ensuring efficient ninhydrin binding. Now, the bound ninhydrin in the GNP carrier, upon chemically reacting with any amino acid, will lead to the formation of Rhumann purple. A common method of GNP production includes citrate reduction of Au [III] derivatives such as aurochloric acid (HAuCl4) in water to Au [0] through a one-step synthesis of size-tunable GNPs. The following reagents are prepared to validate the approach. Reagent A solution 1 is0.0175 grams ninhydrin in 5 ml Millipore water Reagent B 30 µl of HAuCl₄.3H₂O in 3 ml of solution 1 Reagent C 1 µl of gold nanostars in 3 ml of solution 1 Reagent D 6 µl of cetrimonium bromide (CTAB) in 3 ml of solution1 ReagentE 1 µl of gold nanostars in 3 ml of ethanol ReagentF 30 µl of HAuCl₄.₃H₂O in 3 ml of ethanol ReagentG 30 µl of HAuCl₄.₃H₂O in 3 ml of solution 2 ReagentH solution 2 is0.0087 grams ninhydrin in 5 ml Millipore water ReagentI 30 µl of HAuCl₄.₃H₂O in 3 ml of water The reagents were irradiated at 254 nm for 15 minutes, followed by their UV Visible spectroscopy. The wavelength was selected based on the one reported for excitation of a similar molecule Pthalimide. It was observed that the solution B and G deviate around 600 nm, while C peaks distinctively at 567.25 nm and 983.9 nm. Though it is tough to say about the chemical reaction happening, butATR-FTIR of reagents will ensure that ninhydrin is not forming Rhumann purple in the absence of amino acids. Therefore, these experiments, we achieved the functionalization of gold nanostars with ninhydrin corroborated by the deviation in the spectrum obtained in a mixture of GNPs and ninhydrin irradiated with UV light. It prepares them as a carrier molecule totake up amino acids for targeted delivery or germicidal action. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gold%20nanostars" title="gold nanostars">gold nanostars</a>, <a href="https://publications.waset.org/abstracts/search?q=ninhydrin" title=" ninhydrin"> ninhydrin</a>, <a href="https://publications.waset.org/abstracts/search?q=photochemical%20method" title=" photochemical method"> photochemical method</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20visible%20specgtroscopy" title=" UV visible specgtroscopy"> UV visible specgtroscopy</a> </p> <a href="https://publications.waset.org/abstracts/142305/functionalizing-gold-nanostars-with-ninhydrin-as-vehicle-molecule-for-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Influence of Cationic Surfactant (TTAB) on the Rate of Dipeptide (Gly-DL-Asp) Ninhydrin Reaction in Absence and Presence of Organic Solvents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd.%20Akram">Mohd.

The kinetics of the interaction of glycyl-DL-aspartic acid (Gly-DL-Asp) with ninhydrin has been investigated spectrophotometrically in aqueous and organic-solvent media in the absence and presence of cationic surfactant of tetradecyltrimethylammonium bromide (TTAB). The study was carried out under different experimental conditions. The first and fractional order-rate were observed for [Gly-DL-Asp] and [ninhydrin], respectively. The reaction was enhanced about four-fold by TTAB micelles. The effect of organic solvents was studied at a constant concentration of TTAB and showed an increase in the absorbance as well as the rate constant for the formation of product (Ruhemann's purple). The results obtained in micellar media are treated quantitatively in terms of pseudo-phase and Piszkiewicz cooperativity models. The Arrhenius and Eyring equations are valid for the reaction over the range of temperatures used and different activation parameters (Ea, ∆H#, ∆S#, and ∆G#) have been evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glycyl-DL-aspartic%20acid" title="glycyl-DL-aspartic acid">glycyl-DL-aspartic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=ninhydrin" title=" ninhydrin"> ninhydrin</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solvents" title=" organic solvents"> organic solvents</a>, <a href="https://publications.waset.org/abstracts/search?q=TTAB" title=" TTAB"> TTAB</a> </p> <a href="https://publications.waset.org/abstracts/18950/influence-of-cationic-surfactant-ttab-on-the-rate-of-dipeptide-gly-dl-asp-ninhydrin-reaction-in-absence-and-presence-of-organic-solvents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18950.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Textile Dyeing with Natural Dye from Sappan Tree (Caesalpinia sappan Linn.)
