One hundred school going girls vegetarian (n=50) and non-vegetarian (n=50) in the age group of 13-15 years were selected purposively for the study. The data were collected through personal interview technique using the especially structured questionnaire. The general profile, status and educational details of the family, dietary habits and menarcheal profile of the subjects were collected. The height and weight of the subjects were measured by standardized methods. The BMI of the subjects were calculated and categorized accordingly. The academic performance of the girls was measured using the percentage marks obtained by the end of the academic year. Physical activity tests were conducted to assess the physical work capacity by noting the time taken and change in pulse rate after performing the activities as running (100m), jumping (25times) and touching toes (25times). In the study 32% nonvegetarian got higher scores followed by 26% of vegetarian. More than 10% vegetarian and non-vegetarian girls got lower score in academics. The mean difference in the time taken to complete the running and jumping activities came out to be non significant and the time taken to touch toes for vegetarian subjects was 80 Priyanka Pareek and Syeda Ayesha significantly lower as compared to non-vegetarian subjects. The difference was significant for the change in pulse rate after completing the running and jumping activities in both the groups, but difference was non-significant between the groups. In case of toe touching difference was non-significant for the change in pulse rate within both the groups, but difference was significant between the groups, It can be concluded as the non-vegetarian girls were found to be better physical performers. Academically, however they were better than their vegetarian correlates.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"31 1","pages":"79-88"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83379184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To explore the impact of implementing American Association of Critical Care Nurses Endotracheal Tube and Oral Care procedure (AACN ETT& OC) on the rate of Ventilator-associated pneumonia (VAP) development in Jordanian mechanically ventilated patients. Methods A quasi-experimental design with control group was used. Results VAP was statistically significantly higher among the control group, as compared to the intervention group (12.5% and 4% respectively, P <0.01). In the intervention group, the VAP rates decreased by 50% and the mean length of mechanical ventilator usage decreased from 7.3 to 5 days. The mean time to start VAP was extended from 2.3 days in the intervention group to 4.9 days in the control group. A significant decrease was found in mortality rates; from 20% (15/72) in the control group to 13.9% (10/75) in the intervention group, P <0.01. Conclusion Implementation of this procedure reduces hospitalization, morbidity, mortality 260 Abdul-Monim Batiha et al. and improves quality of care. Implications for nursing and health policy The implementation of an AACN ETT& OC can significantly reduce VAP rates, and encourages health policy makers to adapt evidence-based oral and ETT care.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"68 1","pages":"259-273"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89392144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, cancer registry data show that the specific incidence for many forms of cancer increases with age, reaches a maximum, and then decreases. At least two hypotheses have been proposed to explain this decrease: the cell senescence hypothesis and the frailty hypothesis. The objective of our work was to formulate a stochastic model of cancer incidence to estimate the lifetime-independent odds ratio (LIOR) measuring the risk of developing a second primary cancer, conditioned on a first cancer diagnosis, relative to the risk of developing a first primary cancer, in two artificial populations: one where cancer susceptibility is universal and one where only a small proportion of individuals are born susceptible, or frail, to developing one or more cancers. The predicted LIOR values were significantly greater than 1, only 180 Luis Francisco Soto-Ortiz and James P. Brody when a frailty effect was introduced in the model. This result suggests that if a limited proportion of the United States population were innately susceptible to developing cancer, this would be reflected in a LIOR value significantly greater than 1. In addition, the model predicts that the smaller the pool of susceptibles in a population, the larger the computed LIOR value would be. This one-to-one mapping between a LIOR value and the corresponding proportion of susceptibles indicates that a LIOR value could be used to indirectly estimate the proportion of individuals born predisposed to developing a particular type of cancer. Moreover, this result raises the possibility that a LIOR value could be used as a metric to assess how the relative risk of developing a second primary cancer, varies by cancer type in a given geographical region.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"5 1","pages":"179-202"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75179637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is therefore essential to refold and purify the protein to simultaneously increase the production yield and reduce the required downstream steps. Methods: Inclusion bodies were dissolved in Tris-HCl buffer containing 6 M guanidine and applied to a newly designed poly-arginine anion exchange chromatography system. Different reduced-oxidized glutathione amount were employed for refolding the target protein. The refolded proteins were applied to gel filtration chromatography and subjected to biological activity assessment. Results: By increasing the sample volume, the refolding efficacy, purification factor and potency were significantly decreased. This reduction can be highest when only 2 column volumes of the glutathione redox pair presented in the column. The highest values of these factors were obtained when 4 column volumes of the glutathione redox pair offered to the column. To achieve better results, the proportion of sample volume and the amount of passed glutathione redox pair through column should be optimized. Consistent with the increase of sample volume to 1250 μl at any levels of glutathione redox pair there was a significant drop in all factor values. Conclusion: Poly-arginine anion exchange matrix is a new artificial chaperone that can improve the refolding and purification process simultaneously with high efficacy. Therefore, we present poly-arginine anion exchange chromatography as an alternative method for protein refolding with promising commercial and developmental potential.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"3 1","pages":"365-375"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75833749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
