From this number, it can be estimated that the total dried seaweed consumption for this production was at least 300,000 ton/year. The protein content of these types of seaweed is 5 – 25%. If just half of this total amount of protein could be extracted, 18,000 ton/year of a high-value protein product would be obtained. The overall aim of this study was to develop a technology that will ensure further utilization of the seaweed that is used only as raw materials for carrageenan production as single extraction at present. More specifically, proteins should be extracted from the seaweed either before or after extraction of carrageenan with focus on maintaining the quality of carrageenan as a main product. Different mechanical, chemical and enzymatic technologies were evaluated. The optimized process was implemented in lab scale and based on its results; the new experiments were done a pilot and larger scale. In order to calculate the efficiency of the new upstream multi-extraction process, protein content was tested before and after extraction. After this step, the extraction of carrageenan was done and carrageenan content and the effect of extraction on yield were evaluated. The functionality and quality of carrageenan were measured based on rheological parameters. The results showed that by using the new multi-extraction process (submitted patent); it is possible to extract almost 50% of total protein without any negative impact on the carrageenan quality. Moreover, compared to the routine carrageenan extraction process, the new multi-extraction process could increase the yield of carrageenan and the rheological properties such as gel strength in the final carrageenan had a promising improvement. The extracted protein has initially been screened as a plant protein source in typical food applications. Further work will be carried out in order to improve properties such as color, solubility, and taste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title="carrageenan">carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a>, <a href="https://publications.waset.org/abstracts/search?q=seaweed" title=" seaweed"> seaweed</a> </p> <a href="https://publications.waset.org/abstracts/89064/protein-extraction-by-enzyme-assisted-extraction-followed-by-alkaline-extraction-from-red-seaweed-eucheuma-denticulatum-spinosum-used-in-carrageenan-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89064.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">284</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> Mass Transfer of Paracetamol from the Crosslinked Carrageenan-Polyvinyl Alcohol Film</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sperisa%20Distantina">Sperisa Distantina</a>, <a href="https://publications.waset.org/abstracts/search?q=Rieke%20Ulfha%20Noviyanti"> Rieke Ulfha Noviyanti</a>, <a href="https://publications.waset.org/abstracts/search?q=Sri%20Sutriyani"> Sri Sutriyani</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadilah%20Fadilah"> Fadilah Fadilah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mujtahid%20Kaavessina"> Mujtahid Kaavessina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, carrageenan extracted from seaweed Eucheuma cottonii was mixed with polyvinyl alcohol (PVA) and then crosslinked using glutaraldehyde (GA).

The aim of this research was to develop a mathematical model that can be used to describe the mass transfer rate of paracetamol from the hydrogel film into buffer solution. The effect of weight ratio carrageenan-PVA (5: 0, 1: 0.5, 1: 1, 1: 2, 0: 5) on the parameters of the mathematical model was investigated also.

Food industries often use preservatives to maintain the physicochemical properties of foods, such as color and texture. These preservatives (e.g., phosphoric acid) are linked with deleterious health effects such as kidney disease. Using gelling agents, carrageenan, and gelatin to make BGJ could improve its physiochemical and textural properties. This study was designed to optimize BGJ-selected physicochemical and textural properties using carrageenan and gelatin. Various black grass jelly formulations (BGJF) were designed using an I-optimal mixture design in Design Expert® software. Data from commercial BGJ were used as a reference during the optimization process. The combination of carrageenan and gelatin added to the formulations was up to 14.38g (~5%), respectively. The results showed that adding 2.5g carrageenan and 2.5g gelatin at approximately 5g (~5%) effectively maintained most of the physiochemical properties with an overall desirability function of 0.81. This formulation was selected as the optimum black grass jelly formulation (OBGJF). The leaching properties and floating duration were measured on the OBGJF and commercial grass jelly for 20 min and 40 min, respectively. The results indicated that OBGJF showed significantly (p<0.0001) lower leaching rate and floating time (p<0.05). Hence, further optimization is needed to increase the floating duration of carrageenan and gelatin-based BGJ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cincau" title="cincau">cincau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesona%20chinensis" title=" Mesona chinensis"> Mesona chinensis</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20grass%20jelly" title=" black grass jelly"> black grass jelly</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a> </p> <a href="https://publications.waset.org/abstracts/164171/optimization-of-black-grass-jelly-formulation-to-reduce-leaching-and-increase-floating-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164171.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">82</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> Characteristics of Smoked Edible Film Made from Myofibril, Collagen and Carrageenan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roike%20Iwan%20Montolalu">Roike Iwan Montolalu</a>, <a href="https://publications.waset.org/abstracts/search?q=Henny%20Adeleida%20Dien"> Henny Adeleida Dien</a>, <a href="https://publications.waset.org/abstracts/search?q=Feny%20Mentang"> Feny Mentang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kristhina%20P.%20Rahael"> Kristhina P.

This due to various advantages such as flexible, strong, transparent, and the price is relatively cheap. However, the plastic polymer also has various disadvantages, such as the transmission monomer contamination into the material to be packed, and waste is non-biodegradable. Edible film (EF) is an up to date materials, generated after the biodegradable packaging materials. The advantages of the EF materials, is the materials can be eat together with food, and the materials can be applied as a coating materials for a widely kind of foods especially snack foods. The aims of this research are to produce and to analyze the characteristics of smoked EF made from carrageenan, myofibril and collagen of Black Marlin (Makaira indica) industrial waste. Smoked EF made with an addition of 0.8 % smoke liquid. Three biopolymers i.e. carrageenan, myofibril, and collagen were used as treatments, and homogenate for 1 hours at speed of 1500 rpm. The analysis carried out on the pH and physical properties i.e. thickness, solubility, tensile strength, % elongation, and water vapor transmission rate (WVTR), as well as on the sensory characteristics of texture i.e. wateriness, firmness, elasticity, hardness, and juiciness of the coated products. The result shown that the higher the concentration the higher the thickness of EF, where as for myofibril proteins appeared higher than carrageenan and collagen. Both of collagen and myofibril shown that concentration of 6% was most soluble, while for carrageenan were in concentration of 2 to 2.5%.

Ceylan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Limited water resources on the earth come first among the most alarming issues. In this respect, several solutions from treatment of waste water to water management have been proposed. Recently, use of hydrogels as soil additive, which is one of the water management ways in agriculture, has gained increasing interest. In traditional agriculture applications, water used with irrigation aim, rapidly flows down between the pore structures in soil, without enough useful for soil. To overcome this fact and increase the abovementioned limit values, recently, several natural based hydrogels have been suggested and tested to find out their efficiency in soil. However, most of these researches have dealt with grafting of synthetic acrylate based monomers on natural gelling agents, most probably due to reinforced of the natural gels. These results motivated us to search a natural based hydrogel formulations, not including any synthetic component, and strengthened with montmorillonite clay instead of any grafting polymerization with synthetic monomer and examine their potential in this field, as well as characterize of them. With this purpose, carrageenan-psyllium/ montmorillonite hybrid hydrogels have been successively prepared. Their swelling capacities were determined both in deionized and tap water and were found to be dependent on the carrageenan, psyllium and montmorillonite ratios, as well as the water type. On the other hand, mechanical tests revealed that especially carrageenan and montmorillonite contents have a great effect on gel strength, which is one of the essential features, preventing the gels from cracking resulted in readily outflow of all the water in the gel without beneficial for soil. They found to reach 0.23 MPa. The experiments carried out with soil indicated that hydrogels significantly improved the water uptake capacities and water retention degrees of the soil from 49 g to 85 g per g of soil and from 32 to 67%, respectively, depending on the ingredient ratios. Also, biodegradation tests demonstrated that all the hydrogels undergo biodegradation, as expected from their natural origin. The overall results suggested that these hybrid hydrogels have a potential for use as soil additive and can be safely used owing to their totally natural structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title="carrageenan">carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel" title=" hydrogel"> hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=psyllium" title=" psyllium"> psyllium</a> </p> <a href="https://publications.waset.org/abstracts/113770/development-of-carrageenan-psylliummontmorillonite-clay-hybrid-hydrogels-for-agriculture-purpose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113770.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">115</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">31</span> Monitoring the Thin Film Formation of Carrageenan and PNIPAm Microgels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Selim%20Kara">Selim Kara</a>, <a href="https://publications.waset.org/abstracts/search?q=Ertan%20Arda"> Ertan Arda</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahrettin%20Dolastir"> Fahrettin Dolastir</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96nder%20Pekcan"> Önder Pekcan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomaterials and thin film coatings play a fundamental role in medical, food and pharmaceutical industries. Carrageenan is a linear sulfated polysaccharide extracted from algae and seaweeds. To date, such biomaterials have been used in many smart drug delivery systems due to their biocompatibility and antimicrobial activity properties. Poly (N-isopropylacrylamide) (PNIPAm) gels and copolymers have also been used in medical applications. PNIPAm shows lower critical solution temperature (LCST) property at about 32-34 °C which is very close to the human body temperature. Below and above the LCST point, PNIPAm gels exhibit distinct phase transitions between swollen and collapsed states. A special class of gels are microgels which can react to environmental changes significantly faster than microgels due to their small sizes. Quartz crystal microbalance (QCM) measurement technique is one of the attractive techniques which has been used for monitoring the thin-film formation process. A sensitive QCM system was designed as to detect 0.1 Hz difference in resonance frequency and 10-7 change in energy dissipation values, which are the measures of the deposited mass and the film rigidity, respectively. PNIPAm microgels with the diameter around few hundred nanometers in water were produced via precipitation polymerization process. 5 MHz quartz crystals with functionalized gold surfaces were used for the deposition of the carrageenan molecules and microgels in the solutions which were slowly pumped through a flow cell. Interactions between charged carrageenan and microgel particles were monitored during the formation of the film layers, and the Sauerbrey masses of the deposited films were calculated. The critical phase transition temperatures around the LCST were detected during the heating and cooling cycles. It was shown that it is possible to monitor the interactions between PNIPAm microgels and biopolymer molecules, and it is also possible to specify the critical phase transition temperatures by using a QCM system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title="carrageenan">carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20transitions" title=" phase transitions"> phase transitions</a>, <a href="https://publications.waset.org/abstracts/search?q=PNIPAm%20microgels" title=" PNIPAm microgels"> PNIPAm microgels</a>, <a href="https://publications.waset.org/abstracts/search?q=quartz%20crystal%20microbalance%20%28QCM%29" title=" quartz crystal microbalance (QCM)"> quartz crystal microbalance (QCM)</a> </p> <a href="https://publications.waset.org/abstracts/70422/monitoring-the-thin-film-formation-of-carrageenan-and-pnipam-microgels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70422.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">231</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> Successful Immobilization of Alcohol Dehydrogenase on Natural and Synthetic Support and Its Reaction on Ethanol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiral%20D.%20Trivedi">Hiral D.

The aim of the present study was to assess the anti-inflammatory activities of the essential oil of rose geranium (RGEO). The chemical composition of the RGEO was investigated by gas chromatography. The major components were citronellol (29.13%), geraniol (12.62%), and citronellyl formate (8.06%). In the carrageenan induced paw edema, five different groups were established and RGEO was administered orally in three different doses. RGEO (100 mg/kg) was able to significantly reduce the paw edema with a comparable effect to that observed with diclofenac, the positive control. In addition, RGEO showed a potent anti-inflammatory activity by topical treatment in the method of croton oil-induced ear edema. When the dose was 5 or 10 ml of RGEO per ear, the inflammation was reduced by 73 and 88%, respectively. This is the first report to demonstrate a significant anti-inflammatory activity of Algerian RGEO. In addition, histological analysis confirmed that RGEO inhibited the inflammatory responses in the skin. Our results indicate that RGEO may have significant potential for the development of novel anti-inflammatory drugs with improved safety profile. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory%20effect" title="anti-inflammatory effect">anti-inflammatory effect</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=citronellol" title=" citronellol"> citronellol</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=Rose%20geranium" title=" Rose geranium"> Rose geranium</a> </p> <a href="https://publications.waset.org/abstracts/41605/rose-geranium-essential-oil-as-a-source-of-new-and-safe-anti-inflammatory-drugs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41605.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">28</span> Anti-Inflammatory, Anti-Nociceptive and Anti-Arthritic Effects of Mirtazapine, Venalfaxine and Escitalopram in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sally%20A.%20El%20Awdan">Sally A.

Methods: Carrageenan model was used to assess effect on acute inflammation. Paw volume were measured at 1, 2, 3 and 4th hour post challenge. Anti-nociceptive effect was evaluated by hot plate method. Chronic inflammation was developed using Complete Freund's Adjuvant (CFA). The animals were injected with Freund’s adjuvant in sub-plantar tissue of the right posterior paw. Paw volume, ankle flexion scores, adjuvant-induced hyperalgesia and serum cytokine levels were assessed. Results: Results obtained demonstrate that mirtazapine, venalfaxine and escitalopram significantly and dose-dependently inhibited carrageenan-induced rat paw oedema. Mirtazapine, venalfaxine and escitalopram increased the reaction time of rats in hot plate test. We observed an increase in paw volume, ankle flexion scores, thermal hyperalgesia, serum levels of interleukin-1β, PGE2 and TNF-α, induced by intraplantar CFA injection. Regular treatment up to 28 days of adjuvant-induced arthritic rats with mirtazapine, venalfaxine and escitalopram showed anti anti-inflammatory and analgesic activities by suppressing the paw volume, recovering the paw withdrawal latency, and by inhibiting the ankle flexion scores in CFA-induced rats. In addition significant reduction in serum levels of interleukin-1β, PGE2 and TNF-α level in arthritic rats was reduced by treatment with drugs. Conclusion: These results suggest that antidepressants have significant anti-inflammatory and anti-nociceptive effects in acute and chronic models in rats, which may be associated with the reduction of interleukin-1β, PGE2 and TNF-α levels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antidepressants" title="antidepressants">antidepressants</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-nociceptive" title=" anti-nociceptive"> anti-nociceptive</a>, <a href="https://publications.waset.org/abstracts/search?q=Complete%20Freund%27s%20Adjuvant" title=" Complete Freund's Adjuvant"> Complete Freund's Adjuvant</a> </p> <a href="https://publications.waset.org/abstracts/28857/anti-inflammatory-anti-nociceptive-and-anti-arthritic-effects-of-mirtazapine-venalfaxine-and-escitalopram-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28857.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">493</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> Impact of Dairy Polysaccharides on Caloric Intake and Postprandial Metabolic Responses in Young Adults</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Umair%20Arshad">Muhammad Umair Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Ishtiaq"> Saima Ishtiaq</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Imran"> Ali Imran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Different polysaccharides contribute towards the management of glycemic and satiety and consequently manage the metabolic syndrome. In the present study, we compared the postprandial glycemic and satiety responses of different dietary polysaccharides when added to milk (2% Milk Fat). The objective of this study was to evaluate different polysaccharides against postprandial glucose, appetite responses, and food intake at subsequent meals. In a repeated measures crossover design, 30 females (18–30 years) consumed 250 ml milk with 2% M.F. (control), or milk with carrageenan (2.5 g), guar gum (2.5 g) and alginate (2.5 g), followed by an ad libitum pizza meal after 120 min. Alginate and guar gum addition resulted in lower caloric intake at subsequent pizza meal. The post-treatment (0–120 min) glucose and average appetite were suppressed by alginate and guar gum (p < 0.0001), with a more pronounced effect of guar gum. However, alginate resulted in lower blood glucose (p < 0.0001) compared with control and carrageenan during post-treatment. Alginate and guar gum, added milk, and other beverages would be beneficial in the short-term regulation of postprandial glycemia and satiety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=satiety" title="satiety">satiety</a>, <a href="https://publications.waset.org/abstracts/search?q=glycemic%20control" title=" glycemic control"> glycemic control</a>, <a href="https://publications.waset.org/abstracts/search?q=milk%20polysaccharides" title=" milk polysaccharides"> milk polysaccharides</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20intake" title=" food intake"> food intake</a> </p> <a href="https://publications.waset.org/abstracts/167098/impact-of-dairy-polysaccharides-on-caloric-intake-and-postprandial-metabolic-responses-in-young-adults" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167098.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">69</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">26</span> In vivo Anti-inflammatory, Analgesic, and Antipyretic Activities of Aqueous Extract of Leaves of Brocchia cinerea (Vis.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisrine%20Chlif">Nisrine Chlif</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Diouri"> Mohammed Diouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Amar%20Bentayeb"> Amar Bentayeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The Leaves of Brocchia cinerea (Vis.) (Asteraceae) is used traditionally and ethnomedicinally to alleviate pain, fever, and inflammation conditions. Objective: The current study investigates the anti-inflammatory, analgesic, and antipyretic activities of aqueous extract of the leaves of Brocchia cinerea (LBC). Material and methods: The extract was screened for anti-inflammatory (carrageenan-induced paw edema) and analgesic (acetic acid-induced writhing) activities in Wistar rats. Before acetic acid or carrageenan injection, rats were orally fed LBC (200 and 400 mg/ kg), Indomethacin (10 mg/kg), or Aspirin (100 mg/kg). The antipyretic effect was studied in brewer’s yeast-induced pyrexia model in rats using Paracetamol (100 mg/kg) as a standard drug. Results: The crude extract tested significantly prevented the increase in paw volume as compared to the control at 200 mg/kg and 400 mg/kg. The LBC treatment significantly inhibited pain at 400 mg/kg with a percent inhibition of 55.82%, as well as showing a significant reduction in hyperpyrexia in rats at 400 mg/kg. LBC extract produced a comparable activity to paracetamol at 100 mg/kg (p <0.01). Conclusion: The results of the present study that the leaves of B. cinerea extract exhibited strongly anti-inflammatory, analgesic, and antipyretic properties and justify the traditional use of this plant in inflammation, pain, and fever. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analgesic" title="analgesic">analgesic</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammation" title=" anti-inflammation"> anti-inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=antipyretic" title=" antipyretic"> antipyretic</a>, <a href="https://publications.waset.org/abstracts/search?q=brocchia%20cinerea" title=" brocchia cinerea"> brocchia cinerea</a> </p> <a href="https://publications.waset.org/abstracts/145552/in-vivo-anti-inflammatory-analgesic-and-antipyretic-activities-of-aqueous-extract-of-leaves-of-brocchia-cinerea-vis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145552.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">159</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">25</span> The Preventive Effect of Date Palm (Phoenixdactylifera) Seed and Fruit Hydroalcoholic Extracts on Carrageenan-Induced Inflammation in Male Rat’s Hind Paw</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siavash%20Azarbani">Siavash Azarbani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Objective: The side effects of NSAIDS drugs have caused the increasing interest of scientists in herbal medicines as alternative treatment. In this study, the effect of anti inflammatory of seed and fruit of date palm hydroalcolic extracts, due to having antioxidants, was studied. Materials and Methods: In this study, the extraxts of date palm seed and fruit were prepared by the maceration method in 70% alcohol. Eighty male rats Wistar, divided into 10 groups of eight in each, 4 groups received different doses (100, 200, 400, and 600 mg/kg) of seed extract, and 4 other groups different doses (100, 200, 400, and 600 mg/kg) of fruits extract of the palm, and the positive control aspirin (300mg/kg) and the negative control group saline (5ml/kg) via injection intraperitoneally. Half an hour later, all animals received 100 µl of 1% carrageenan into the rats hind paw subcutaneous. The changes in rats paw edema was measured by plethysmometer every hour for five hours. Results: The effect of all of the doses of date palm seed extract on edema were less than aspirine (P<0.05). But there was no significant difference between the group that received 400 and 600 mg/kg of date palm fruit extract when compared with the aspirin group. The Dose 400 mg/kg of fruit extract showed the most anti-inflammatory effect, and it was assignded as the best dose. Conclusion: It is likely that with further studies on different model of animals and also on the human model, the palm fruit extract could be used for pain treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=palm" title="palm">palm</a>, <a href="https://publications.waset.org/abstracts/search?q=inflamentory" title=" inflamentory"> inflamentory</a>, <a href="https://publications.waset.org/abstracts/search?q=date" title=" date"> date</a>, <a href="https://publications.waset.org/abstracts/search?q=aspirin" title=" aspirin"> aspirin</a>, <a href="https://publications.waset.org/abstracts/search?q=karageenan" title=" karageenan"> karageenan</a> </p> <a href="https://publications.waset.org/abstracts/155356/the-preventive-effect-of-date-palm-phoenixdactylifera-seed-and-fruit-hydroalcoholic-extracts-on-carrageenan-induced-inflammation-in-male-rats-hind-paw" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155356.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">122</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">24</span> Anti-Inflammatory, Analgesic and Antipyretic Activity of Terminalia arjuna Roxb.

(family Combretaceae) is commonly known as ‘Sa maw thet’ in Thai. The fruit is used in traditional medicine as natural mild laxatives, carminative and expectorant. Aim of the study: This research aims to study the anti-inflammatory, analgesic and antipyretic activities of Terminalia arjuna extract by using animal models in comparison to the reference drugs. Materials and Methods: The anti-inflammatory study was conducted by two experimental animal models namely ethyl phenylpropionate (EPP)-induced ear edema and carrageenan-induced paw edema. The study of analgesic activity used two methods of pain induction including acetic acid and heat-induced pain. In addition, the antipyretic activity study was performed by induced hyperthermia with yeast. Results: The results showed that the oral administration of Terminalia arjuna extract possessed acute anti-inflammatory effect in carrageenan-induced paw edema. Terminalia arjuna extract showed the analgesic activity in acetic acid-induced writhing response and heat-induced pain. This indicates its peripheral effect by inhibiting the biosynthesis and/or release of some pain mediators and some mechanism through Central nervous system. Moreover, Terminalia arjuna extract at the dose of 1000 and 1500 mg/kg body weight showed the antipyretic activity, which might be because of the inhibition of prostaglandins. Conclusion: The findings of this study indicated that the Terminalia arjuna extract possesses the anti-inflammatory, analgesic and antipyretic activities in animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analgesic%20activity" title="analgesic activity">analgesic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory%20activity" title=" anti-inflammatory activity"> anti-inflammatory activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antipyretic%20activity" title=" antipyretic activity"> antipyretic activity</a>, <a href="https://publications.waset.org/abstracts/search?q=Terminalia%20arjuna%20extract" title=" Terminalia arjuna extract"> Terminalia arjuna extract</a> </p> <a href="https://publications.waset.org/abstracts/69530/anti-inflammatory-analgesic-and-antipyretic-activity-of-terminalia-arjuna-roxb-extract-in-animal-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69530.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">264</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">23</span> Antioxidant Potential of Pomegranate Rind Extract Attenuates Pain, Inflammation and Bone Damage in Experimental Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ritu%20Karwasra">Ritu Karwasra</a>, <a href="https://publications.waset.org/abstracts/search?q=Surender%20Singh"> Surender Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inflammation is an important physiological response of the body’s self-defense system that helps in eliminating and protecting organism from harmful stimuli and in tissue repair. It is a highly regulated protective response which helps in eliminating the initial cause of cell injury, and initiates the process of repair. The present study was designed to evaluate the ameliorative effect of pomegranate rind extract on pain and inflammation. Hydroalcoholic standardized rind extract of pomegranate at doses 50, 100 and 200 mg/kg and indomethacin (3 mg/kg) was tested against eddy’s hot plate induced thermal algesia, carrageenan (acute inflammation) and Complete Freund’s Adjuvant (chronic inflammation) induced models in Wistar rats. Parameters analyzed were inhibition of paw edema, measurement of joint diameter, levels of GSH, TBARS, SOD, TNF-α, radiographic imaging, tissue histology and synovial expression of pro-inflammatory cytokine receptor (TNF-R1). Radiological and light microscopical analysis were carried out to find out the bone damage in CFA-induced chronic inflammatory model. Findings of the present study revealed that pomegranate rind extract at a dose of 200 mg/kg caused a significant (p<0.05) reduction in paw swelling in both the inflammatory models. Nociceptive threshold was also significantly (p<0.05) improved. Immunohistochemical analysis of TNF-R1 in CFA-induced group showed elevated level, whereas reduction in level of TNF-R1 was observed in pomegranate (200 mg/kg). Henceforth, we might say that pomegranate produced a dose-dependent reduction in inflammation and pain along with the reduction in levels of oxidative stress markers and tissue histology, and the effect was found to be comparable to that of indomethacin. Thus, it can be concluded that pomegranate is a potential therapeutic target in the pathogenesis of inflammation and pain, and punicalagin is the major constituents found in rind extract might be responsible for the activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title="carrageenan">carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=nociceptive-threshold" title=" nociceptive-threshold"> nociceptive-threshold</a>, <a href="https://publications.waset.org/abstracts/search?q=pomegranate" title=" pomegranate"> pomegranate</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a> </p> <a href="https://publications.waset.org/abstracts/53481/antioxidant-potential-of-pomegranate-rind-extract-attenuates-pain-inflammation-and-bone-damage-in-experimental-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53481.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">219</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">22</span> Evaluation of κ -Carrageenan Hydrogel Efficiency in Wound-Healing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ayatic">Ali Ayatic</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Mozaffari"> Emad Mozaffari</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahareh%20Tanhaei"> Bahareh Tanhaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Khajenoori"> Maryam Khajenoori</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeedeh%20Movaghar%20Khoshkho"> Saeedeh Movaghar Khoshkho</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ayati"> Ali Ayati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The abuse of antibiotics, such as tetracycline (TC), is a great global threat to people and the use of topical antibiotics is a promising tact that can help to solve this problem. Antibiotic therapy is often appropriate and necessary for acute wound infections, while topical tetracycline can be highly efficient in improving the wound healing process in diabetics. Due to the advantages of drug-loaded hydrogels as wound dressing, such as ease of handling, high moisture resistance, excellent biocompatibility, and the ability to activate immune cells to speed wound healing, it was found as an ideal wound treatment. In this work, the tetracycline-loaded hydrogels combining agar (AG) and κ-carrageenan (k-CAR) as polymer materials were prepared, in which span60 surfactant was introduced inside as a drug carrier. The Field Emission Scanning Electron Microscopes (FESEM) and Fourier-transform infrared spectroscopy (FTIR) techniques were employed to provide detailed information on the morphology, composition, and structure of fabricated drug-loaded hydrogels and their mechanical properties, and hydrogel permeability to water vapor was investigated as well. Two types of gram-negative and gram-positive bacteria were used to explore the antibacterial properties of prepared tetracycline-contained hydrogels. Their swelling and drug release behavior was studied using the changing factors such as the ratio of polysaccharides (MAG/MCAR), the span60 surfactant concentration, potassium chloride (KCl) concentration and different release media (deionized water (DW), phosphate-buffered saline (PBS), and simulated wound fluid (SWF)) at different times. Finally, the kinetic behavior of hydrogel swelling was studied. Also, the experimental data of TC release to DW, PBS, and SWF using various mathematical models such as Higuchi, Korsmeyer-Peppas, zero-order, and first-order in the linear and nonlinear modes were evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20release" title="drug release">drug release</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel" title=" hydrogel"> hydrogel</a>, <a href="https://publications.waset.org/abstracts/search?q=tetracycline" title=" tetracycline"> tetracycline</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing" title=" wound healing"> wound healing</a> </p> <a href="https://publications.waset.org/abstracts/155969/evaluation-of-k-carrageenan-hydrogel-efficiency-in-wound-healing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155969.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">80</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">21</span> Mechanical Properties of Hybrid Cement Based Mortars Containing Two Biopolymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Abdollahnejad">Z.

Rice bran, a 10.5% constituent of rice grain, is a by-product of rice milling process. Rice bran is normally used as a raw material for rice bran oil production or sold as feed with a low price. Therefore, this study aimed to increase value of defatted rice bran as obtained after extracting of rice bran oil. Conventionally, the protein in defatted rice bran was extracted using alkaline extraction and acid precipitation, which results in reduction of nutritious components in rice bran. Rice bran protein concentrate is suitable for those who are allergenic of protein from other sources eg. milk, wheat. In addition to its hypoallergenic property, rice bran protein also contains good quantity of lysine. Thus it may act as a suitable ingredient for infant food formulations while adding variety to the restricted diets of children with food allergies. The objectives of this study were to compare properties of rice bran protein concentrate (RBPC) extracted from defatted rice bran using enzymes together with precipitation step using polysaccharides (alginate and carrageenan) to those of a control sample extracted using a conventional method. The results showed that extraction of protein from rice bran using enzymes exhibited the higher protein recovery compared to that extraction with alkaline. The extraction conditions using alcalase 2% (v/w) at 50 C, pH 9.5 gave the highest protein (2.44%) and yield (32.09%) in extracted solution compared to other enzymes. Rice bran protein concentrate powder prepared by a precipitation step using alginate (protein in solution: alginate 1:0.006) exhibited the highest protein (27.55%) and yield (6.62%). Precipitation using alginate was better than that of acid. RBPC extracted with alkaline (ALK) or enzyme alcalase (ALC), then precipitated with alginate (AL) (samples RBP-ALK-AL and RBP-ALC-AL) yielded the precipitation rate of 75% and 91.30%, respectively. Therefore, protein precipitation using alginate was then selected. Amino acid profile of control sample, and sample precipitated with alginate, as compared to casein and soy protein isolated, showed that control sample showed the highest content among all sample. Functional property study of RBP showed that the highest nitrogen solubility occurred in pH 8-10. There was no statically significant between emulsion capacity and emulsion stability of control and sample precipitated by alginate. However, control sample showed a higher of foaming and lower foam stability compared to those of sample precipitated with alginate. The finding was successful in terms of minimizing chemicals used in extraction and precipitation steps in preparation of rice bran protein concentrate. This research involves in a production of value-added product in which the double amount of protein (28%) compared to original amount (14%) contained in rice bran could be beneficial in terms of adding to food products eg. healthy drink with high protein and fiber. In addition, the basic knowledge of functional property of rice bran protein concentrate was obtained, which can be used to appropriately select the application of this value-added product from rice bran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alginate" title="alginate">alginate</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20bran" title=" rice bran"> rice bran</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20bran%20protein" title=" rice bran protein "> rice bran protein </a> </p> <a href="https://publications.waset.org/abstracts/26710/extraction-of-rice-bran-protein-using-enzymes-and-polysaccharide-precipitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26710.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">295</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">19</span> The Hidden Mechanism beyond Ginger (Zingiber officinale Rosc.)

The aim of our study was to search for the mechanism of ginger (Zingiber officinale Roscoe) anti-inflammatory potential and to correlate it to its biophytochemicals. Methods: Various extracts viz. water, 50%, 70%, 80%, and 90% ethanol were prepared from ginger rhizomes. Fractionation of the aqueous extract (AE) was accomplished using Diaion HP-20. In vitro anti-inflammatory activity of the different extracts and isolated compounds was evaluated by protein denaturation inhibition, membrane stabilization, protease inhibition, and anti-lipoxygenase assays. In vivo anti-inflammatory activity of AE was estimated by assessment of rat paw oedema after carrageenan injection. Prostaglandin E2 (PGE2), certain inflammation markers (TNF-α, IL-6, IL-1α, IL-1β, INFr, MCP-1MIP, RANTES, and Nox) levels and MPO activity in the paw edema exudates were measured. Total antioxidant capacity (TAC) was also determined. Histopathological alterations of paw tissues were scored. Results: All the tested extracts showed significant (p < 0.1) anti-inflammatory activities. The highest percentage of heat induced albumin denaturation (66%) was exhibited by the 50% ethanol (250 μg/ml). The 70 and 90% ethanol extracts (500 μg/ml) were more potent as membrane stabilizers (34.5 and 37%, respectively) than diclofenac (33%). The 80 and 90% ethanol extracts (500 μg/ml) showed maximum protease inhibition (56%). The strongest anti-lipoxygenase activity was observed for the AE. It showed more significant lipoxygenase inhibition activity than that of diclofenac (58% and 52%, respectively) at the same concentration (125 μg/ml). Fractionation of AE yielded four main fractions (Fr I-IV) which showed significant in vitro anti-inflammatory. Purification of Fr-III and IV led to the isolation of 6-poradol (G1), 6-shogaol (G2); methyl 6- gingerol (G3), 5-gingerol (G4), 6-gingerol (G5), 8-gingerol (G6), 10-gingerol (G7), and 1-dehydro-6-gingerol (G8). G2 (62.5 ug/ml), G1 (250 ug/ml), and G8 (250 ug/ml) exhibited potent anti-inflammatory activity in all studied assays, while G4 and G5 exhibited moderate activity. In vivo administration of AE ameliorated rat paw oedema in a dose-dependent manner. AE (at 200 mg/kg) showed significant reduction (60%) of PGE2 production. The AE at different doses (at 25-200 mg/kg) showed significant reduction in inflammatory markers except for IL-1α. AE (at 25 mg/kg) is superior to indomethacin in reduction of IL-1β. Treatment of animals with the AE (100, 200 mg/kg) or indomethacin (10 mg/kg) showed significant reduction in TNF-α, IL-6, MCP-1, and RANTES levels, and MPO activity by about (31, 57 and 32% ) (65, 60 and 57%) (27, 41 and 28%) (23, 32 and 23%) (66, 67 and 67%) respectively. AE at 100 and 200 mg/kg was equipotent to indomethacin in reduction of NOₓ level and in increasing the TAC. Histopathological examination revealed very few inflammatory cells infiltration and oedema after administration of AE (200 mg/kg) prior to carrageenan. Conclusion: Ginger anti-inflammatory activity is mediated by inhibiting macrophage and neutrophils activation as well as negatively affecting monocyte and leukocyte migration. Moreover, it produced dose-dependent decrease in pro-inflammatory cytokines and chemokines and replenished the total antioxidant capacity. We strongly recommend future investigations of ginger in the potential signal transduction pathways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-lipoxygenase%20activity" title="anti-lipoxygenase activity">anti-lipoxygenase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20markers" title=" inflammatory markers"> inflammatory markers</a>, <a href="https://publications.waset.org/abstracts/search?q=1-dehydro-6-gingerol" title=" 1-dehydro-6-gingerol"> 1-dehydro-6-gingerol</a>, <a href="https://publications.waset.org/abstracts/search?q=6-shogaol" title=" 6-shogaol"> 6-shogaol</a> </p> <a href="https://publications.waset.org/abstracts/74482/the-hidden-mechanism-beyond-ginger-zingiber-officinale-rosc-potent-in-vivo-and-in-vitro-anti-inflammatory-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74482.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">252</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">18</span> Restoration and Conservation of Historical Textiles Using Covalently Immobilized Enzymes on Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elbehery">Mohamed Elbehery</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Historical textiles in the burial environment or in museums are exposed to many types of stains and dirt that are associated with historical textiles by multiple chemical bonds that cause damage to historical textiles. The cleaning process must be carried out with great care, with no irreversible damage, and sediments removed without affecting the original material of the surface being cleaned. Science and technology continue to provide innovative systems in the bio-cleaning process (using pure enzymes) of historical textiles and artistic surfaces. Lipase and α-amylase were immobilized on nanoparticles of alginate/κ-carrageenan nanoparticle complex and used in historical textiles cleaning. Preparation of nanoparticles, activation, and enzymes immobilization were characterized. Optimization of loading time and units of the two enzymes were done. It was found that, the optimum time and units of amylase were 4 hrs and 25U, respectively. While, the optimum time and units of lipase were 3 hrs and 15U, respectively. The methods used to examine the fibers using a scanning electron microscope equipped with an X-ray energy dispersal unit: SEM with EDX unit. <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=enzymes" title=" enzymes"> enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization" title=" immobilization"> immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=textiles" title=" textiles"> textiles</a> </p> <a href="https://publications.waset.org/abstracts/166234/restoration-and-conservation-of-historical-textiles-using-covalently-immobilized-enzymes-on-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166234.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">99</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">17</span> Evaluation of Anti-Inflammatory Activities in Wild Herb Urginea wightii</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Hemalata">S.

Urginea wightii is a member of Hyacinthaceae and considered to be wonder plant because of its varied important medicinal properties. The plant is endemic to India, Africa, and Mediterranian regions. Presence of alkaloids, flavonoid-glycosides especially flavonone derivatives are responsible for the strong anti-inflammatory activity of Urginea wightii. In present research work, anti-inflammatory activity of methanol extract of the bulb powder was tested on Male Wistar Rats. In these test animals, inflammation was induced by injecting carrageenan as the irritant to induce paw edema in Wistar rats. Inflammation of Paw edema was treated with both plant extract and Pyrox gel a known synthetic anti-inflammatory drug through external application. The result indicated that anti-inflammatory activity of Urginea wightii extract was almost similar to the synthetic Pyrox gel. This disproves the modern world's scepticism towards the herbal medicines and encourages to rely on natural plant extracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory%20activity" title="anti-inflammatory activity">anti-inflammatory activity</a>, <a href="https://publications.waset.org/abstracts/search?q=flavonoid-glycosides" title=" flavonoid-glycosides"> flavonoid-glycosides</a>, <a href="https://publications.waset.org/abstracts/search?q=Pyrox%20gel" title=" Pyrox gel"> Pyrox gel</a>, <a href="https://publications.waset.org/abstracts/search?q=Urginia%20wightii" title=" Urginia wightii"> Urginia wightii</a> </p> <a href="https://publications.waset.org/abstracts/76175/evaluation-of-anti-inflammatory-activities-in-wild-herb-urginea-wightii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76175.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">169</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">16</span> Design, Synthesis, and Evaluation of Small Peptides for Managing Inflammation: Inhibition to Substrate Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Palwinder%20Singh">Palwinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Baljit%20Kaur"> Baljit Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukhmeet%20Kaur"> Sukhmeet Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Amongst a library of rationally designed small peptides, (H)Gly-Gly-Phe-Leu(OMe) was identified, reducing prostaglandin production of COX-2 with IC50 60 nM vs. 6000 nM for COX-1. The 5 mg Kg-1 dose of this compound rescued albino mice by 80% from capsaicin-induced paw licking and recovered it by 60% from carrageenan-induced inflammation. The mode of action of the compound for targeting COX-2, iNOS, and VGSC was investigated by using substances P, L-arginine, and veratrine, respectively, as the biomarkers. The interactions of the potent compound with COX-2 were supported by the isothermal calorimetry experiments showing Ka 6.10±1.10x104 mol-1 and ΔG -100.3 k J mol-1 in comparison to Ka 0.41x103 ±0.09 mol-1 and ΔG -19.2±0.06 k J mol-1 for COX-1. This compound did not show toxicity up to 2000 mg Kg-1 dose. Furthermore, beyond the conventional mode of working with anti-inflammatory agents through enzyme inhibition, COX-2 was provided with a peptide-based alternate substrate. Proline-centered pentapeptide iso-conformational to arachidonic acid exhibited appreciable selectivity for COX-2 overcoming acetic acid and formalin-induced pain in rats to almost 80% and was treated as a substrate by the enzyme. Hence, we suggest small peptides as highly potent and promising candidates for their further development into an anti-inflammatory drug. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20peptides" title="small peptides">small peptides</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclooxygenase" title=" cyclooxygenase"> cyclooxygenase</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate" title=" substrate"> substrate</a> </p> <a href="https://publications.waset.org/abstracts/160257/design-synthesis-and-evaluation-of-small-peptides-for-managing-inflammation-inhibition-to-substrate-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160257.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">88</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">15</span> Modelling Water Vapor Sorption and Diffusion in Hydrocolloid Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Terhemen%20Tyowua">Andrew Terhemen Tyowua</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhibing%20Zhang"> Zhibing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20J.%20Adams"> Michael J.

The results reveal that the data may be more accurately described by an existing sigmoidal rather than a Fickian model. The sigmoidal model accounts for the initial surface sorption before the onset of bulk diffusion. At relatively small water activities (≤ 0.3), the absorption of the moisture caused the particles to be plasticized, but at greater activity values (> 0.3), anti-plasticization was induced. However, it was found that for the whole range of water activities and temperatures studied, the data could be characterized by a single non-dimensional number, which was termed the non-Fickian diffusion number where τ is the characteristic time of surface sorption, D is the bulk diffusion coefficient and L is the thickness of the layer of particles. The activation energy suggested that the anti-plasticization mechanism was the result of a reduction in the molecular free volume or an increase in crystallinity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-plasticization" title="anti-plasticization">anti-plasticization</a>, <a href="https://publications.waset.org/abstracts/search?q=arrhenius%20behavior" title=" arrhenius behavior"> arrhenius behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20coefficient" title=" diffusion coefficient"> diffusion coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=hygroscopic%20polymers" title=" hygroscopic polymers"> hygroscopic polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20migration" title=" moisture migration"> moisture migration</a>, <a href="https://publications.waset.org/abstracts/search?q=non-fickian%20sigmoidal%20model" title=" non-fickian sigmoidal model"> non-fickian sigmoidal model</a> </p> <a href="https://publications.waset.org/abstracts/186885/modelling-water-vapor-sorption-and-diffusion-in-hydrocolloid-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186885.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">30</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">14</span> Analysis of the Effect of Food Veils on the Preservation of Button and Oyster Mushrooms, Case Study: Zein Corn Coating</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=Hamid%20Tavakkolipour"> Hamid Tavakkolipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdis%20Jamshidi%20Tehranian"> Mahdis Jamshidi Tehranian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The inclination toward using food coatings is increasing daily, due to containing natural elements and not producing environmental pollution. Food coatings are uniform and thin layers of natural substances that cover the food product and act as a barrier against moisture, oxygen, and substances dissolved in food. Using food coatings on fruits and vegetables can delay water dissipation, losing aroma, decolorization, and improve the appearance of the product, and in general, preserve and protect the quality of fresh produce. When fruits and vegetables grow, they are equipped with a natural shield, called cuticle– a layer of wax. Washing the products, after harvest, the cuticle – this protective coating – is removed. In order to replace the cuticle, we can use an edible protective coating. This coating delays dehydration and deterioration and hence increases the life of the product while keeping its moisture. In this study, it was concluded that using food coatings, such as corn zein, carrageenan, and starch can have a substantial effect on the quantitative and qualitative preservation of food products, such as fruits, vegetables, and mushrooms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20coating" title="food coating">food coating</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20zein" title=" corn zein"> corn zein</a>, <a href="https://publications.waset.org/abstracts/search?q=button%20and%20oyster%20mushrooms" title=" button and oyster mushrooms"> button and oyster mushrooms</a>, <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20and%20citric%20acids" title=" ascorbic and citric acids"> ascorbic and citric acids</a> </p> <a href="https://publications.waset.org/abstracts/69368/analysis-of-the-effect-of-food-veils-on-the-preservation-of-button-and-oyster-mushrooms-case-study-zein-corn-coating" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69368.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">299</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">13</span> New Applications of Essential Oils: Edible Packaging Material for Food Supplements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roxana%20Gheorghita">Roxana Gheorghita</a>, <a href="https://publications.waset.org/abstracts/search?q=Gheorghe%20Gutt"> Gheorghe Gutt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental pollution due to non-degradation of packaging from the food and pharmaceutical industry is reaching increasingly alarming levels. The packaging used for food supplements is usually composed of successive layers of synthetic materials, conventional, glue, and paint. The situation is becoming more and more problematic as the population, according to statistics, uses food supplements more and more often. The solution can be represented by edible packaging, completely biodegradable, and compostable. The tested materials were obtained from biopolymers, agar, carrageenan, and alginate, in well-established quantities and plasticized with glycerol. Rosemary, thyme, and oregano essential oils have been added in varying proportions. The obtained films are completely water-soluble in hot liquids (with a temperature of about 80° C) and can be consumed with the product contained. The films were glossy, pleasant to the touch, thin (thicknesses between 32.8 and 52.8 μm), transparent, and with a pleasant smell, specific to the added essential oil. Tested for microbial evaluation, none of the films indicated the presence of E. coli, S. aureus, enterobacteria, coliform bacteria, yeasts, or molds. This aspect can also be helped by the low values of the water activity index (located between 0.546 and 0.576). The mechanical properties indicated that the material became more resistant with the addition of essential oil, the best values being recorded by the addition of oregano. The results obtained indicate the possibility of using biopolymer-based films with the addition of rosemary, thyme, and oregano essential oil, for wrapping food supplements, thus replacing conventional packaging, multilayer, impossible to sort and recycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=edible%20films"
