This study was conducted in the quantitative research, and the questionnaires were used to collect data from 400 people of the sample group. Descriptive statistics were used in data analysis. The findings reveal that most participants have positive comments regarding the series. They strongly agreed that the series reflects on the way of life and problems of teenagers in Thailand. Hence, the participants believe that if adults have a chance to watch the series, they will have the better understanding of the teenagers. In addition, the participants also agreed that the contents of the play are appropriate and satisfiable as the contents of “Hormones the Series Season 2” will raise awareness among the teens and use it as a guide to prevent problems that might happen during their teenage life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=content%20analysis" title="content analysis">content analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=Thai%20series" title=" Thai series"> Thai series</a>, <a href="https://publications.waset.org/abstracts/search?q=hormones%20the%20Series" title=" hormones the Series"> hormones the Series</a> </p> <a href="https://publications.waset.org/abstracts/39934/content-analysis-and-attitude-of-thai-students-towards-thai-series-hormones-season-2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39934.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">229</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">2809</span> Sense Environmental Hormones in Elementary School Teachers and Their in Service Learning Motivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fu-Chi%20Chuang">Fu-Chi Chuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Liang"> Yu-Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang"> Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Der%20Wang"> Wen-Der Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our environment has been contaminated by many artificial chemicals, such as plastics, pesticides. Many of them have hormone-like activity and are classified as 'environmental hormone (also named endocrine disruptors)'. These chemicals interfere with or mimic hormones have adverse effects that persist into adulthood. Environmental education is an important way to teach students to become engaged in real-world issues that transcend classroom walls. Elementary education is the first stage to perform environmental education and it is an important component to help students develop adequate environmental knowledge, attitudes, and behavior. However, elementary teachers' knowledge plays a critical role in this mission. Therefore, we use a questionnaire to survey the knowledge of environmental hormone of elementary school teachers and their learning motivation of the environmental hormone-regarding knowledge. We collected 218 questionnaires from Taiwanese elementary teachers and the results indicate around 73% of elementary teachers do not have enough knowledge about environmental hormones. Our results also reveal the in-service elementary teachers’ learning motivation of environmental hormones knowledge is positively enhanced once they realized their insufficient cognitive ability of environmental hormones. We believe our study will provide the powerful reference for Ministry of Education to set up the policy of environmental education to enrich all citizens sufficient knowledge of the effects of the environmental hormone on organisms, and further to enhance our correct environmental behaviors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elementary%20teacher" title="elementary teacher">elementary teacher</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20hormones" title=" environmental hormones"> environmental hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20motivation" title=" learning motivation"> learning motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=questionnaire" title=" questionnaire"> questionnaire</a> </p> <a href="https://publications.waset.org/abstracts/104093/sense-environmental-hormones-in-elementary-school-teachers-and-their-in-service-learning-motivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104093.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">313</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">2808</span> Effect of Organic Zinc in Supplement Diet on Some Reproryductive Hormones and Fertility in Laboratory Mice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azade%20Sedigh">Azade Sedigh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Modaresi"> Mehrdad Modaresi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Pirestani"> Akbar Pirestani </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Appropriate nutrition is necessary today for desire reproduction and profitable livestock industry. Minerals including zinc element are from nutritional factors. Studies show that zinc plays an important role in reproduction process and secretion of reproductive hormones. This study was carried out to determine the effects of organic zinc on some reproductive hormones, fertility of male mice. The study was done as completely randomized design with one control and six treatment groups. Seventy male mature mice were kept for 35 days to adapt to environment and then divided in seven groups with ten replications. Samples received zinc (organic) daily in 50,100, and 150 ppm doses of each type for 35 days. At the end, blood samples were taken to measure LH, FSH, and testosterone hormones. Meanwhile, fertility rates were measured. Results were analyzed using one way ANOVA and means were compared using Duncan multiple ranges test at 5% probability level. According to results, LH concentration of all groups except 50 ppm was increased significantly (p<0.05). FSH amount was increased significantly (p<0.05) in 100 ppm mineral group and reduced in 50 ppm mineral but was not changed in other groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20supplements" title="organic supplements">organic supplements</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc" title=" zinc"> zinc</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20hormones" title=" reproductive hormones"> reproductive hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility" title=" fertility"> fertility</a> </p> <a href="https://publications.waset.org/abstracts/17846/effect-of-organic-zinc-in-supplement-diet-on-some-reproryductive-hormones-and-fertility-in-laboratory-mice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17846.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">468</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">2807</span> Bioproduction of Phytohormones by Liquid Fermentation Using a Mexican Strain of Botryodiplodia theobromae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laredo%20Alcal%C3%A1%20Elan%20I%C3%B1aky">Laredo Alcalá Elan Iñaky</a>, <a href="https://publications.waset.org/abstracts/search?q=Hernandez%20Castillo%20Daniel"> Hernandez Castillo Daniel</a>, <a href="https://publications.waset.org/abstracts/search?q=Martinez%20Hernandez%20Jos%C3%A9%20Luis"> Martinez Hernandez José Luis</a>, <a href="https://publications.waset.org/abstracts/search?q=Arredondo%20Valdes%20Roberto"> Arredondo Valdes Roberto</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonzalez%20Gallegos%20Esmeralda"> Gonzalez Gallegos Esmeralda</a>, <a href="https://publications.waset.org/abstracts/search?q=Anguiano%20Cabello%20Julia%20Cecilia"> Anguiano Cabello Julia Cecilia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plant hormones are a group of molecules that control different processes ranging from the growth and development of the plant until their response to biotic and abiotic stresses. In this study, the capacity of production of various phytohormones was evaluated from a strain of Botryodiplodia theobromae by liquid fermentation system using the modified Mierch medium added with a hydrolyzate compound of mead all in a reactor without agitation at 28 °C for 15 days. Quantification of the metabolites was performed using high performance liquid chromatography techniques. The results showed that a microbial broth with at least five different types of plant hormones was obtained: gibberellic acid, zeatin, kinetin, indoleacetic acid and jasmonic acid, the last one was higher than the others metabolites produced. The production of such hormones using a single type of microorganism could be in the future a great alternative to reduce production costs and similarly reduce the use of synthetic chemicals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosystem" title="biosystem">biosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20hormones" title=" plant hormones"> plant hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=Botryodiplodia%20theobromae" title=" Botryodiplodia theobromae"> Botryodiplodia theobromae</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/43134/bioproduction-of-phytohormones-by-liquid-fermentation-using-a-mexican-strain-of-botryodiplodia-theobromae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43134.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">403</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">2806</span> Rapid Proliferation of Tissue Culture Using of Olive (Olea Europea L.) cv.Zard</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Gharaipour%20Abbasabad">Majid Gharaipour Abbasabad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research is studying the effects that various densities of Zeatin, and BA hormones may have on the scale of transformation of plant nodes to new shoots, among seedlings produced by seed germination, and also surveys the amount of produced shoots and their lengths, inside the specific Olive seed lab medium (OM). It is also concerned with the effects that various densities of IBA hormone, and inoculating the shoots with Agrobacterium Rhizogenez A4 can have on shoots' root production. This is a totally random research, and each attendance group has had three occurrences, and ten samples per a hectare. The average amounts have been compared using Duncan's test method, which was done in 5% level. The results indicated that the highest rate of transformation of micro samples to shoots happened in the seed germination environments, containing Zetain with 5 mg, and also 15 mg per a liter densities. (respectively, 95% and 94%), while the highest rate of plants' stem production ,in micro samples, happened in the lab medium environments with 5mg per a liter Zetain density (4.5). In lab medium environments with 15 mg Zetain per liter, a decrease was observed in the number of produced stems (3.88). According to the produced stems' lenght, the longest stem length was observed in environments with 5 mg and also 15 mg per a liter Zetain, and 25 mg per a liter BA densities (respectively, 8.45 cm, 45.66 cm, 8.53 cm). Meanwhile, the lowest amount of transformation of micro samples to shoots, the lowest number of produced shoots, and the shortest shoots were observed in the environments without any hormones (respectively, 3.32 cm, 1.13, 19.66%). The results of root production in Olive indicated that attendance groups which were exposed to different hormones did not vary, and Agrobacterium Rhizogenez A4 had no effect on them, as well. The lowest root's growth rate (22%) happened in environments without any hormones and also, in environment with Agrobacterium Rhizogenez A4 (19.66%). The largest number of roots was observed in the environments, containing Agrobacterium Rhizogenez A4 plus IBA (10 mg/l) and Agrobacterium Rhizogenez A4 plus IBA (10 mg/l), (respectively, 8.46 and 8.70), which had a significant difference with environments merely containing 10 mg and 20 mg of IBA per a litre (respectively, 3.06 and 3.2). So it can be concluded that even though Agrobacterium Rhizogenez A4 had no impact on root's growth among shoots, it had an impact on the number of produced roots. It should be noted that even when the environment contained merely Agrobacterium Rhizogenez A4 without any hormones, only (1.16) roots were produced, which is significantly different from the attendance group with hormones (1.06). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=olive-effect%20of%20hormones-germination%20of%20seed" title="olive-effect of hormones-germination of seed">olive-effect of hormones-germination of seed</a>, <a href="https://publications.waset.org/abstracts/search?q=densities%20of%20zeatin" title=" densities of zeatin"> densities of zeatin</a>, <a href="https://publications.waset.org/abstracts/search?q=BA%20hormones" title=" BA hormones"> BA hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/14822/rapid-proliferation-of-tissue-culture-using-of-olive-olea-europea-l-cvzard" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14822.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">2805</span> Effects of PAHs on Blood Thyroidal Hormones of Liza klunzingeri in the Northern Part of Hormuz Strait (Persian Gulf)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fateme%20Afkhami">Fateme Afkhami</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Ehsanpour"> Mohsen Ehsanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Ehsanpour"> Maryam Ehsanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Afkhami"> Majid Afkhami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted to determine the effects of polycyclic aromatic hydrocarbons (PAHs) on thyroidal hormones of Liza klunzingeri and to monitor marine pollution from northern part of Hormuz strait (Persian Gulf).

The present study was conducted to investigate the useful effects of vitamin E on reproductive functions of Teddy bucks. For this purpose, 8 adult Teddy bucks were randomly divided into two treatment groups viz; A (control) and B (vitamin E with dose of 200 mg/kg BW/day). These treatments continued for 12 weeks. Semen quality parameters (volume, motility, sperm morphology and sperm DNA integrity) of experimental bucks of each group was evaluated on weekly basis, while testicular measurements (length, scrotal circumference and weights) were recorded at 0 and 12th week of experiment. Serum concentrations of male sex hormones (testosterone, LH, FSH) and cortisol were recorded fortnightly. Similarly, body weights of bucks were also measured fortnightly until completion of the study. The data were subjected to two-way analysis of variance, followed by Duncan test for multiple mean comparisons. Supplementation of vitamin E improved significantly (P<0.05) the semen quality parameter, body weights, testicular measurements and serum levels of sex hormones. However, there was no effect on serum cortisol. It was concluded from the present study that dietary supplementation of vitamin E has beneficial effects on the semen and hormones in male reproductive system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hormones" title="hormones">hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=semen" title=" semen"> semen</a>, <a href="https://publications.waset.org/abstracts/search?q=teddy%20bucks" title=" teddy bucks"> teddy bucks</a>, <a href="https://publications.waset.org/abstracts/search?q=testicular%20measurements" title=" testicular measurements"> testicular measurements</a> </p> <a href="https://publications.waset.org/abstracts/54209/effects-of-dietary-e-on-semen-hormonal-profile-and-testicular-biometry-in-teddy-goat-bucks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54209.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">2803</span> Factors Influencing the Acceptance of Y Series among the Residents in Three Southern Border Provinces of Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chetsada%20Noknoi">Chetsada Noknoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The acceptance of Y series refers to the willingness and enjoyment of watching Y series without feeling different from general series. This occurs when people watch Y series and derive happiness and entertainment from it. The viewing experience has the most significant impact on Y series acceptance. This research aims to 1) investigate the levels of acceptance of sexual diversity, image of Y series Actors, media exposure, and Y series acceptance among the residents in three southern border provinces of Thailand, and 2) examine how acceptance of sexual diversity, actor perceptions in Y series, and media exposure influence Y series acceptance in these provinces. The sample consisted of 322 participants from the three southern border provinces of Thailand. The research instrument used was a questionnaire, and data were analyzed using frequency, percentage, mean, standard deviation, and multiple regression analysis. The findings revealed that overall, acceptance of sexual diversity, Image of Y series Actors, and Y series acceptance among the residents in three southern border provinces of Thailand were at a high level, while media exposure was moderate overall. However, the two factors that had the most significant impact on Y series acceptance in these provinces, ranked from highest to lowest influence, were media exposure and acceptance of sexual diversity. Both of these factors had a positive effect on Y series acceptance among the residents in three southern border provinces of Thailand. Collectively, these factors accounted for 40.7% of the variance in Y series acceptance among the residents in three southern border provinces of Thailand. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acceptance" title="acceptance">acceptance</a>, <a href="https://publications.waset.org/abstracts/search?q=acceptance%20of%20sexual%20diversity" title=" acceptance of sexual diversity"> acceptance of sexual diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20of%20Y%20series%20actors" title=" image of Y series actors"> image of Y series actors</a>, <a href="https://publications.waset.org/abstracts/search?q=media%20exposure" title=" media exposure"> media exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=Y%20series" title=" Y series"> Y series</a> </p> <a href="https://publications.waset.org/abstracts/174083/factors-influencing-the-acceptance-of-y-series-among-the-residents-in-three-southern-border-provinces-of-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174083.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">77</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">2802</span> Dependence of Androgen Status in Men with Primary Hypothyroidism on Duration and Condition of Compensation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Krytskyy%20T.">Krytskyy T.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The role of androgen deficiency in men as a factor in the pathogenesis of many somatic diseases is unmistakable. The interaction of thyroid and sex hormones with hypothyroidism in men is still the subject of discussions. The purpose of the study is to assess the androgen status of men with primary hypothyroidism, depending on its duration and the state of compensation. Materials and methods: 45 men with primary hypothyroidism aged 35 to 60 years, as well as 25 healthy men, who formed a control group, were under supervision. A selection of men for examination was conducted in the process of outpatient and in-patient treatment at the endocrinology department of the University Hospital in Ternopil. The functional state of the pituitary-gonadal system was evaluated in order to characterize the androgen status of patients. The concentration of follicle stimulating hormone, luteinizing hormone, prolactin, thyroid-stimulating hormone was determined in blood with the help of enzyme-linked method. Also, the content of hormones: total testosterone, linking sex hormones globulin were determined. Results: Reduced total testosterone (TT) content was found in 42.2% of patients with hypothyroidism. Herewith in 17.8% of patients, blood TT levels were lower than 8.0 nmol / L, and in 11 (24.4%) men, the rate was in the range of 8.0 to 12.0 nmol / L. Based on the results of the determination of the content of free testosterone (FT), the frequency of laboratory hypogonadism in men with hypothyroidism was higher than the results of the determination of TT. The degree of compensation of hypothyroidism probably did not affect the average levels of gonadotropic and sex hormones. Conclusions: Reduced total testosterone content was found in 42.2% of patients with primary hypothyroidism. Herewith, in 17.8% of patients blood TT levels were lower than 8.0 nmol / L, which is a sign of absolute deficiency of testosterone, and in 24.4% of men the rate ranged from 8.0 to 12.0 nmol / l , indicating partial androgen deficiency. Linking sex hormones globulin levels were believed to be lower in 46.7% of patients with hypothyroidism compared to control group. The average levels of E2 in the examined patients did not significantly differ from the mean of control group. FSH, LH, and prolactin levels in men with hypothyroidism were within the normal age limits and probably did not differ from those of control group. The degree of compensation of hypothyroidism probably did not affect the average levels of gonadotropic and sex hormones. The mean LH content in the blood was significantly increased in men with a duration of hypothyroidism up to 5 years and did not differ from that of the control group and in men with a duration of hypothyroidism over 5 years. In men with hypothyroidism, a probable reduction in T / LH coefficient is found. The obtained data may indicate a combined lesion of the central and peripheral parts of the pituitary-gonadal system in men with hypothyroidism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=androgenic%20status" title="androgenic status">androgenic status</a>, <a href="https://publications.waset.org/abstracts/search?q=hypothyroidism" title=" hypothyroidism"> hypothyroidism</a>, <a href="https://publications.waset.org/abstracts/search?q=testosterone" title=" testosterone"> testosterone</a>, <a href="https://publications.waset.org/abstracts/search?q=linking%20sex%20hormones%20globulin" title=" linking sex hormones globulin"> linking sex hormones globulin</a> </p> <a href="https://publications.waset.org/abstracts/96829/dependence-of-androgen-status-in-men-with-primary-hypothyroidism-on-duration-and-condition-of-compensation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96829.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">195</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">2801</span> The Cooperation among Insulin, Cortisol and Thyroid Hormones in Morbid Obese Children and Metabolic Syndrome </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orkide%20Donma">Orkide Donma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20M.%20Donma"> Mustafa M. Donma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obesity, a disease associated with a low-grade inflammation, is a risk factor for the development of metabolic syndrome (MetS). So far, MetS risk factors such as parameters related to glucose and lipid metabolisms as well as blood pressure were considered for the evaluation of this disease. There are still some ambiguities related to the characteristic features of MetS observed particularly in pediatric population. Hormonal imbalance is also important, and quite a lot information exists about the behaviour of some hormones in adults. However, the hormonal profiles in pediatric metabolism have not been cleared yet. The aim of this study is to investigate the profiles of cortisol, insulin, and thyroid hormones in children with MetS. The study population was composed of morbid obese (MO) children without (Group 1) and with (Group 2) MetS components. WHO BMI-for age and sex percentiles were used for the classification of obesity. The values above 99 percentile were defined as morbid obesity. Components of MetS (central obesity, glucose intolerance, high blood pressure, high triacylglycerol levels, low levels of high density lipoprotein cholesterol) were determined. Anthropometric measurements were performed. Ratios as well as obesity indices were calculated. Insulin, cortisol, thyroid stimulating hormone (TSH), free T<sub>3</sub> and free T<sub>4 </sub>analyses were performed by electrochemiluminescence immunoassay. Data were evaluated by statistical package for social sciences program. p<0.05 was accepted as the degree for statistical significance. The mean ages±SD values of Group 1 and Group 2 were 9.9±3.1 years and 10.8±3.2 years, respectively. Body mass index (BMI) values were calculated as 27.4±5.9 kg/m<sup>2</sup> and 30.6±8.1 kg/m<sup>2</sup>, successively. There were no statistically significant differences between the ages and BMI values of the groups. Insulin levels were statistically significantly increased in MetS in comparison with the levels measured in MO children. There was not any difference between MO children and those with MetS in terms of cortisol, T<sub>3</sub>, T<sub>4</sub> and TSH. However, T<sub>4</sub> levels were positively correlated with cortisol and negatively correlated with insulin. None of these correlations were observed in MO children. Cortisol levels in both MO as well as MetS group were significantly correlated. Cortisol, insulin, and thyroid hormones are essential for life. Cortisol, called the control system for hormones, orchestrates the performance of other key hormones. It seems to establish a connection between hormone imbalance and inflammation. During an inflammatory state, more cortisol is produced to fight inflammation. High cortisol levels prevent the conversion of the inactive form of the thyroid hormone T<sub>4</sub> into active form T<sub>3</sub>. Insulin is reduced due to low thyroid hormone. T<sub>3</sub>, which is essential for blood sugar control- requires cortisol levels within the normal range. Positive association of T<sub>4</sub> with cortisol and negative association of it with insulin are the indicators of such a delicate balance among these hormones also in children with MetS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children" title="children">children</a>, <a href="https://publications.waset.org/abstracts/search?q=cortisol" title=" cortisol"> cortisol</a>, <a href="https://publications.waset.org/abstracts/search?q=insulin" title=" insulin"> insulin</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid%20hormones" title=" thyroid hormones"> thyroid hormones</a> </p> <a href="https://publications.waset.org/abstracts/91666/the-cooperation-among-insulin-cortisol-and-thyroid-hormones-in-morbid-obese-children-and-metabolic-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91666.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">2800</span> Jacobson Semisimple Skew Inverse Laurent Series Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Moussavi">Ahmad Moussavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we are concerned with the Jacobson semisimple skew inverse Laurent series rings R((x−1; α, δ)) and the skew Laurent power series rings R[[x, x−1; α]], where R is an associative ring equipped with an automorphism α and an α-derivation δ.

Biological control of the snail intermediate hosts of Schistosoma is one of the promising methods for eliminating this disease in Egypt. The molluscicidal activity of exotoxins secreted from Bacillus subtilis bacteria was studied. The effect of these exotoxins was studied on the fecundity of Biomphalaria alexandrina snails the intermediate host of Schistosoma mansoni; the fecundity includes the reproductive rate (R0) of B. alexandrina snails and levels of sex hormones (progesterone, testosterone, and estradiol). Moreover, the cercarial production of S. mansoni was determined. The results showed a significant reduction in the egg-laying capacity of the treated snails after exposure to sublethal concentrations ( LC10 and LC25) of B. Subtilis exotoxins; this reduction reached 70% at LC25. Moreover, B. Subtilis exotoxins' significantly suppressed the cercarial production of B. alexandrina snails. It is concluded that the exotoxins of Bacillus subtilis bacteria play an important role in the interference of the Schistosomiasis transmission, hence should be applied in the strategy of schistosomiasis control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=schistosomiasis" title="schistosomiasis">schistosomiasis</a>, <a href="https://publications.waset.org/abstracts/search?q=Biomphalaria%20alexandrina%20snails" title=" Biomphalaria alexandrina snails"> Biomphalaria alexandrina snails</a>, <a href="https://publications.waset.org/abstracts/search?q=Bacillus%20subtilis%20bacteria" title=" Bacillus subtilis bacteria"> Bacillus subtilis bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=fecundity" title=" fecundity"> fecundity</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20hormones" title=" sex hormones"> sex hormones</a> </p> <a href="https://publications.waset.org/abstracts/111495/impact-of-bacillus-subtilis-exotoxins-on-fecundity-sex-hormones-and-release-of-schistosoma-mansoni-cercariae-in-biomphalaria-alexandrina-snails" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111495.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">135</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">2798</span> The Effect of Acute Toxicity and Thyroid Hormone Treatments on Hormonal Changes during Embryogenesis of Acipenser persicus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samaneh%20Nazeri">Samaneh Nazeri</a>, <a href="https://publications.waset.org/abstracts/search?q=Bagher%20Mojazi%20Amiri"> Bagher Mojazi Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Farahmand"> Hamid Farahmand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production of high quality fish eggs with reasonable hatching rate makes a success in aquaculture industries. It is influenced by the environmental stimulators and inhibitors. Diazinon is a widely-used pesticide in Golestan province (Southern Caspian Sea, North of Iran) which is washed to the aquatic environment (3 mg/L in the river). It is little known about the effect of this pesticide on the embryogenesis of sturgeon fish, the valuable species of the Caspian Sea. Hormonal content of the egg is an important factor to guaranty the successful passes of embryonic stages. In this study, the fate of Persian sturgeon embryo to 24, 48, 72, and 96-hours exposure of diazinon (LC<sub>50</sub> dose) was tested. Also, the effect of thyroid hormones (T3 and T4) on these embryos was tested concurrently or separately with diazinon LC <sub>50</sub> dose. Fertilized eggs are exposed to T3 (low dose: 1 ng/ml, high dose: 10 ng/ml), T4 (low dose: 1 ng/ml, high dose: 10 ng/ml). Six eggs were randomly selected from each treatment (with three replicates) in five developmental stages (two cell- division, neural, heart present, heart beaten, and hatched larvae). The possibility of changing T3, T4, and cortisol contents of the embryos were determined in all treated groups and in every mentioned embryonic stage. The hatching rate in treated groups was assayed at the end of the embryogenesis to clarify the effect of thyroid hormones and diazinon. The results indicated significant differences in thyroid hormone contents, but no significant differences were recognized in cortisol levels at various early life stages of embryos. There was also significant difference in thyroid hormones in (T3, T4) + diazinon treated embryos (<em>P</em>˂0.05), while no significant difference between control and treatments in cortisol levels was observed. The highest hatching rate was recorded in HT3 treatment, while the lowest hatching rate was recorded for diazinon LC<sub>50</sub> treatment. The result confirmed that Persian sturgeon embryo is less sensitive to diazinon compared to teleost embryos, and thyroid hormones may increase hatching rate even in the presence of diazinon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Persian%20sturgeon" title="Persian sturgeon">Persian sturgeon</a>, <a href="https://publications.waset.org/abstracts/search?q=diazinon" title=" diazinon"> diazinon</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid%20hormones" title=" thyroid hormones"> thyroid hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=cortisol" title=" cortisol"> cortisol</a>, <a href="https://publications.waset.org/abstracts/search?q=embryo" title=" embryo"> embryo</a> </p> <a href="https://publications.waset.org/abstracts/57048/the-effect-of-acute-toxicity-and-thyroid-hormone-treatments-on-hormonal-changes-during-embryogenesis-of-acipenser-persicus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57048.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">303</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">2797</span> Series "H154M" as a Unit Area of the Region between the Lines and Curves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hisyam%20Hidayatullah">Hisyam Hidayatullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This world events consciously or not realize everything has a pattern, until the events of the universe according to the Big Bang theory of the solar system which makes so regular in the rotation.

This study illustrated that audiences might even construct a hierarchy according to the origin countries when consuming certain products. Chinese audiences now have access to TV series from all around the world thanks to the internet. TV series from different origin countries show some particular features in terms of length, theme, plots, accessibility, seriousness etc. Their audiences were therefore stereotyped because of what they watch. Based on in-depth interviews with 20 participants, this research has following findings: 1) Most popular origin countries of foreign TV series in China are Korea, the United States, the United Kingdom, Japan and European countries in a descending order. Korean TV series are most popular because they are less serious and more accessible compared to others. 2) In the hierarchy of the TV series, European TV series stand on the top followed by British and American TV series. Japanese TV series are also categorized into highbrow class. Korean TV series are at the bottom and always seen as lowbrow cultural products. 3) Most audiences consume TV series from more than one origin countries and have different needs when watching them. Participants reported that they watch European TV series because those TV series are more artistic than their counterparts and of great quality. They watch British and American TV series mainly to improve their English and to learn about the culture. They find Japanese TV series very enjoyable with a large variety of themes and impressive lines. Audiences watch Korean TV series mostly to entertain and kill time. 4) Audiences do care about cultural taste. Especially those who watch European, British and American TV series usually tend to consider audiences who watch nothing but Korean TV series to be shallow. On the other hand, Korean TV series’ audiences seem to care less about the hierarchy of the TV series. Even when they discuss the hierarchy, they tend to accept the judgments with ironies and jokes. Future studies can dig deeply into the genre and content of TV series with different origin countries and also investigate more about the psychology of audiences regarding the gender, age, education, socioeconomic status etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foreign%20TV%20series" title="foreign TV series">foreign TV series</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchy" title=" hierarchy"> hierarchy</a>, <a href="https://publications.waset.org/abstracts/search?q=popularity" title=" popularity"> popularity</a>, <a href="https://publications.waset.org/abstracts/search?q=uses%20and%20gratification" title=" uses and gratification"> uses and gratification</a> </p> <a href="https://publications.waset.org/abstracts/53622/a-study-on-hierarchy-and-popularity-of-foreign-tv-series-with-different-origin-countries-among-chinese-audiences-from-a-uses-and-gratification-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53622.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">243</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">2795</span> Stability Analysis for an Extended Model of the Hypothalamus-Pituitary-Thyroid Axis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beata%20Jackowska-Zduniak">Beata Jackowska-Zduniak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We formulate and analyze a mathematical model describing dynamics of the hypothalamus-pituitary-thyroid homoeostatic mechanism in endocrine system.

In conclusion, The present study approved the poorly ovarian activities and reproduction disturbance of infertile cows in spite of trigger estrous signs, The study confirmed a positive correlation between inhibins and NO to regulate the ovarian physiology. These inhibins represent effective markers of dairy cows infertility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cows" title="cows">cows</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibins%20A%20and%20B" title=" inhibins A and B"> inhibins A and B</a>, <a href="https://publications.waset.org/abstracts/search?q=infertility" title=" infertility"> infertility</a>, <a href="https://publications.waset.org/abstracts/search?q=nitric%20oxide%20%28NO%29" title=" nitric oxide (NO)"> nitric oxide (NO)</a> </p> <a href="https://publications.waset.org/abstracts/1332/investigation-the-difference-of-several-hormones-correlated-to-reproduction-between-infertile-and-fertile-dairy-cows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1332.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">288</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">2793</span> Effects of Conjugated Linoleic Acid (CLA) on Hormones and Factors Involved in Murine Ovulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Karshenas">Leila Karshenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Khodaei"> Hamidreza Khodaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnaz%20Mahdavi"> Behnaz Mahdavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ovulation is a physiologic process with an inflammatory response that depends on a coordinated activity of gonadotropins and steroid hormones, as well as inflammatory mediators such as cytokines, prostaglandins, leptin, nitric oxide (NO), etc. Conjugated linoleic acid (CLA) is composed of polyunsaturated fatty acids (PUFA) found in dairy products, beef and lamb. There is strong evidence that dietary CLA affects mediators involved in ovulation. The aim of this study was to determine the effects of different doses of dietary CLA on systemic and local hormones and factors involved in ovulation. In this case-control study, 80 (50±2-day old) female mice were randomly divided into four groups (C as the controls and T1, T2 and T3 as the treatment groups). There were four replicates in each group and there were five mice in every replicate (20 mice, in total). The mice in the control group were fed with no CLA in their diet but the ones in the treatment group received 0.1, 0.3 and 0.5g/kg of CLA (replacing corn oil in the diet), respectively for 120 days. Later on, blood samples were obtained from the tails of animals that displayed estrus signs and estradiol (E2), progesterone (P4), LH, FSH, NO, leptin and TNFα were measured. Furthermore, the effects of CLA on the ovarian production of prostaglandins (PGs) and NO were investigated. The data were analyzed by SAS software.CLA significantly decreased serum levels of FSH (p<0.05), LH, estradiol, NO, leptin and TNFα (p<0.01). In addition, CLA decreased progesterone levels but this effect was statistically insignificant. The significantly negative effects of CLA were seen on the ovarian production of PGE2 and PGF2α (p<0.01).It seems that CLA may play an effective role in reducing the ovulation rate in mice as CLA adversely affected female reproduction and it had negative effects on systemic and local hormones involved in ovulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conjugated%20linoleic%20acid" title="conjugated linoleic acid">conjugated linoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=nitric%20oxide" title=" nitric oxide"> nitric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=ovary" title=" ovary"> ovary</a>, <a href="https://publications.waset.org/abstracts/search?q=ovulation" title=" ovulation"> ovulation</a>, <a href="https://publications.waset.org/abstracts/search?q=prostaglandin" title=" prostaglandin"> prostaglandin</a>, <a href="https://publications.waset.org/abstracts/search?q=gonadotropin" title=" gonadotropin"> gonadotropin</a> </p> <a href="https://publications.waset.org/abstracts/12655/effects-of-conjugated-linoleic-acid-cla-on-hormones-and-factors-involved-in-murine-ovulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12655.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">301</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">2792</span> Innate Immunity of Insects in Brief</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Soleymaninejadian">Ehsan Soleymaninejadian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the field of immunology is growing day by day, and its chaotic system amazes more people, greed of research in this area is growing; however dealing with human or mammalian cells such as mice make the research expensive. Although there are some differences between higher animals with insects, importance of innate immunity during evolution made it untouched. So, for understanding the innate immunity insects can be good models. They are cheap; reproduction is fast and in the case genetics, less complicated. In this review, we tried to briefly tackle with important factors in insects’ innate immunity such as melanization, encapsulation, JAK-STAT, IMD, and Toll pathways. At the end, we explained how hormones and nerve system also can impact on immune system and make it more beautiful. In concluding remarks, the possibility of taking help from insect immune system to fight against diseases such as cancer has been considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=insects" title="insects">insects</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunity" title=" innate immunity"> innate immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=melanization" title=" melanization"> melanization</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20pathways" title=" intracellular pathways"> intracellular pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=hormones" title=" hormones"> hormones</a> </p> <a href="https://publications.waset.org/abstracts/74600/innate-immunity-of-insects-in-brief" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74600.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">226</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">2791</span> Effect of Hormones Priming on Enzyme Activity and Lipid Peroxidation in Wheat Seed under Accelerated Aging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Abbasi">Amin Abbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fariborz%20Shekari"> Fariborz Shekari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Bahman%20Mousavi"> Seyed Bahman Mousavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seed aging during storage is a complex biochemical and physiological processes that can lead to reduce seed germination. This phenomenon associated with increasing of total antioxidant activity during aging. To study the effects of hormones on seed aging, aged wheat seeds (control, 90 and 80% viabilities) were treated with GA3, Salicylic Acid, and paclobutrazol and antioxidant system were investigated as molecular biomarkers for seed vigor. The results showed that, seed priming treatment significantly affected germination percentage, normality seedling percentage, H2O2, MDA, CAT, APX, and GPX activates. Maximum germination percentage achieve in GA3 priming in control treatment. Germination percentage and normal seedling percentage increased in other GA3 priming treatment compared with other hormones. Also aging increased MDA, H2O2 content. MDA is considered sensitive marker commonly used for assessing membrane lipid peroxidation and H2O2result in toxicity to cellular membrane system and damages to plant cells. Amount of H2O2 and MDA declined in GA3 treatment. CAT, GPX and APX activities were reduced by increasing the aging time and at different levels of priming. The highest APX activity was observed in Salicylic Acid control treatment and the highest GPX and CAT activity was obtained in GA3 control treatment. The lowest MDA and H2O2 showed in GA3 control treatment, too. Hormone priming increased Antioxidant enzyme activity and decreased amount of reactive oxygen space and malondialdehyde (MDA) under aging treatment. Also, GA3 priming treatments have a significant effect on germination percentage and number of normal seedling. Generally aging seed, increase ROS and lipid peroxidation. Antioxidant enzymes activity of aged seeds increased after hormone priming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hormones%20priming" title="hormones priming">hormones priming</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=aging%20seed" title=" aging seed"> aging seed</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</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/3560/effect-of-hormones-priming-on-enzyme-activity-and-lipid-peroxidation-in-wheat-seed-under-accelerated-aging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3560.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">496</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">2790</span> Possible Endocrinal and Liver Enzymes Toxicities Associated with Long Term Exposure to Benzene in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faizah%20Asiri">Faizah Asiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Fathy"> Mohammed Fathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Alghamdi"> Saeed Alghamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahlah%20Ayoub"> Nahlah Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Asiri"> Faisal Asiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: - The strategies for this study were based on the toxic effect of long-term inhalation of Benzene on hormones and liver enzymes and various parameters related to it. The following databases were searched: benzene, hepatotoxic, benzene metabolism, hormones, testosterone, hemotoxic, and prolonged exposure. A systematic strategy is designed to search the literature that links benzene with the multiplicity and different types of intoxication or the medical abbreviations of diseases relevant to benzene exposure. Evidence suggests that getting rid of inhaled gasoline is by exhalation. Absorbed benzene is metabolized by giving phenolic acid as well as meconic acid, followed by urinary excretion of conjugate sulfates and glucuronides. Materials and Methods :- This work was conducted in the Al-Khadra laboratory in Taif 2020/2021 and aimed to measure some of the possible endocrinal and liver toxicities associated with benzene's long-term exposure in Saudi Arabia at the station workers who are considered the most exposed category to gasoline. One hundred ten station workers were included in this study. They were divided into four patient groups according to the chronic exposure rate to benzene, one control group, and three other groups of exposures. As follows: patient Group 1 (controlled group), patient Group 2 (exposed less than 1y), patient Group 3 (exposed 1-5 y), patient Group 4 (more than 5). Each group is compared with blood sample parameters (ALT, FSH and Testosterone, TSH). Blood samples were drawn from the participants, and statistical tests were performed. Significant change (p≤0.05) was examined compared to the control group. Workers' exposure to benzene led to a significant change in hematological, hormonal, and hepatic factors compared to the control group. Results:- The results obtained a relationship between long-term exposure to benzene and a decrease in the level of testosterone and FSH hormones, including that it poses a toxic risk in the long term (p≤0.05) when compared to the control. We obtained results confirming that there is no significant coloration between years of exposure and TSH level (p≤0.05) when compared to the control. Conclusion:- We conclude that some hormones and liver enzymes are affected by chronic doses of benzene through inhalation after our study was on the group most exposed to benzene, which is gas station workers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=toxicities" title="toxicities">toxicities</a>, <a href="https://publications.waset.org/abstracts/search?q=benzene" title=" benzene"> benzene</a>, <a href="https://publications.waset.org/abstracts/search?q=hormones" title=" hormones"> hormones</a>, <a href="https://publications.waset.org/abstracts/search?q=station%20workers" title=" station workers"> station workers</a> </p> <a href="https://publications.waset.org/abstracts/171051/possible-endocrinal-and-liver-enzymes-toxicities-associated-with-long-term-exposure-to-benzene-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171051.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">87</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">2789</span> Distributed Perceptually Important Point Identification for Time Series Data Mining</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tak-Chung%20Fu">Tak-Chung Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ying-Kit%20Hung"> Ying-Kit Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu-Lai%20Chung"> Fu-Lai Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the field of time series data mining, the concept of the Perceptually Important Point (PIP) identification process is first introduced in 2001. This process originally works for financial time series pattern matching and it is then found suitable for time series dimensionality reduction and representation. Its strength is on preserving the overall shape of the time series by identifying the salient points in it. With the rise of Big Data, time series data contributes a major proportion, especially on the data which generates by sensors in the Internet of Things (IoT) environment. According to the nature of PIP identification and the successful cases, it is worth to further explore the opportunity to apply PIP in time series ‘Big Data’. However, the performance of PIP identification is always considered as the limitation when dealing with ‘Big’ time series data. In this paper, two distributed versions of PIP identification based on the Specialized Binary (SB) Tree are proposed. The proposed approaches solve the bottleneck when running the PIP identification process in a standalone computer. Improvement in term of speed is obtained by the distributed versions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distributed%20computing" title="distributed computing">distributed computing</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20analysis" title=" performance analysis"> performance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Perceptually%20Important%20Point%20identification" title=" Perceptually Important Point identification"> Perceptually Important Point identification</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series%20data%20mining" title=" time series data mining"> time series data mining</a> </p> <a href="https://publications.waset.org/abstracts/84358/distributed-perceptually-important-point-identification-for-time-series-data-mining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84358.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">433</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">2788</span> Influence of Conjugated Linoleic Acid on Hormones of Axis of Female Reproduction System Involved in Ovulation Process </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Khodaei">Hamidreza Khodaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Daryabeigi%20Zand"> Ali Daryabeigi Zand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ovulation is a physiologic process with an inflammatory response that depends on a coordinated activity of gonadotropins and steroid hormones, and inflammatory mediators such as cytokines, prostaglandins, leptin, nitric oxide (NO), etc. Conjugated linoleic acid (CLA) is composed of polyunsaturated fatty acids (PUFA) found in dairy products, beef, and lamb.

Also, a necessary and sufficient condition for the L1-convergence of the cosine and sine series is deduced as corollaries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conjugate%20Dirichlet%20kernel" title="conjugate Dirichlet kernel">conjugate Dirichlet kernel</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirichlet%20kernel" title=" Dirichlet kernel"> Dirichlet kernel</a>, <a href="https://publications.waset.org/abstracts/search?q=L1-convergence" title=" L1-convergence"> L1-convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20sums" title=" modified sums"> modified sums</a> </p> <a href="https://publications.waset.org/abstracts/44182/l1-convergence-of-modified-trigonometric-sums" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44182.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">354</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">2784</span> Investigation on Performance of Change Point Algorithm in Time Series Dynamical Regimes and Effect of Data Characteristics </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Asadi">Farhad Asadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Javad%20Mollakazemi"> Mohammad Javad Mollakazemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, Bayesian online inference in models of data series are constructed by change-points algorithm, which separated the observed time series into independent series and study the change and variation of the regime of the data with related statistical characteristics. variation of statistical characteristics of time series data often represent separated phenomena in the some dynamical system, like a change in state of brain dynamical reﬂected in EEG signal data measurement or a change in important regime of data in many dynamical system. In this paper, prediction algorithm for studying change point location in some time series data is simulated. It is verified that pattern of proposed distribution of data has important factor on simpler and smother fluctuation of hazard rate parameter and also for better identification of change point locations.

Tričković</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present the results concerned with trigonometric series that include sine and cosine functions with a parameter appearing in the denominator. We derive two types of closed-form formulas for trigonometric series. At first, for some integer values, as we know that Riemann’s ζ function and Dirichlet η, λ equal zero at negative even integers, whereas Dirichlet’s β function equals zero at negative odd integers, after a certain number of members, the rest of the series vanishes. Thus, a trigonometric series becomes a polynomial with coefficients involving Riemann’s ζ function and Dirichlet η, λ, β functions. On the other hand, in some cases, one cannot immediately replace the parameter with any positive integer because we shall encounter singularities. So it is necessary to take a limit, so in the process, we apply L’Hospital’s rule and, after a series of rearrangements, we bring a trigonometric series to a form suitable for the application of Choi-Srivastava’s theorem dealing with Hurwitz’s zeta function and Harmonic numbers. In this way, we express a trigonometric series as a polynomial over Hurwitz’s zeta function derivative. <p class="card-text"><strong>Keywords:</strong> <a
