Due to the limited number of commercial tomato cultivars with resistance to this disease, control is mainly through cultural practices and heavy use of fungicides. The appearance of fungicide-resistant P. infestans genotypes, however, necessitates identification of new genetic sources of host resistance to the disease and subsequent breeding of new resistant cultivars. Several new sources of resistance to tomato LB were identified in a recent screening of the tomato related wild species S. pimpinellifolium. In the present study, we examined the genetic basis of LB resistance in accession PI 270442, through parent-offspring correlation analysis, generation means analysis, and analysis of response to selection, using populations derived from crosses with a LB-susceptible tomato breeding line. 14 Matthew T. Sullenberger and Majid R. Foolad Across experiments, estimates of heritability (h) for LB resistance ranged from 0.56 – 0.86, suggesting the heritable nature of this resistance and possibility of effectively transferring LB resistance from PI 270442 to the cultivated tomato genetic background through phenotypic selection and traditional backcross breeding. Genetic mapping studies are currently underway to identify the associated molecular markers for LB resistance in PI 270442.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"44 1","pages":"13-32"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81218580","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}

Methodology: Five hundred and twelve critical care nurses were recruited from the Intensive Care Units (ICU), Emergency Rooms (ER) and Operation Rooms (OR) from six major hospitals in Amman, Jordan. Participants singed an informed consent and answered, sociodemographic questionnaire, in addition to Hospital Anxiety and Depression Scale, Fatigue Severity Scale, and Insomnia Severity Index. Results: Critical care nurses who were working on night shift have higher levels of insomnia, depression, anxiety, and fatigue than nurses working on day shift or temporary night. Furthermore, female and ICU nurses experienced more fatigue than male nurses and nurses from OR and ER respectively. There was a dose-response relationship between the number of night that nurses work in the previous year with their (insomnia, depression, and fatigue levels) Conclusion: Night shift work induced insomnia for nurses working in critical care units which increased their anxiety, depression and fatigue levels.

The World Health Organization highlighted the seriousness of TFAs intake and called to ban TFAs from foods or to limit their intake to less than 1% of the total amount of the energy intake. Fast foods are considered to have a high percentage of TFAs. University students spend most of their time outside home which makes them the suitable population to consume these kinds of food. The purpose of this descriptive study was to assess the University of Jordan students' concerns and awareness about TFAs. Four hundred and seventeen students answered a self-reported questionnaire about TFAs from October, 2015-January, 2016. Descriptive statistics, independent sample t test and multiple regression were used to analyze the data. Results showed that students at the University of Jordan were found to have moderate concern relevant to TFAs (Mean± 64 Hekmat Yousef Al-Akash et al. SD; 20.0 ± 5.1), and moderate awareness relevant to TFAs health risks (Mean± SD; 51.5± 15.2). Awareness was predicted from the faculty of students (health faculties), female gender, living status, and family income, which explained 30% of the variance. In conclusion, it is known that high levels of TFAs are associated with increased risk of cardiovascular diseases and obesity, especially in young adults. The results of this study showed that concern and awareness of the students about health risks and dietary sources of TFAs was insufficient to make decisions of healthier food selection.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"81 1","pages":"63-81"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84309117","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}

For preparing Large Unilamellar Vesicles, Phosphatidylcholine and Cholesterol are solved in Ether and then Ceftazidime is added to this mixture, and after affecting this mixture by Sonicator, the uniform suspension is produced and then evaporates under vacuum condition in Rotary Evaporator until the thin layer is remained around the basin.

This phenomenon is considered to be the most important factor limiting the growth and productivity of forest plants in arid and semi-arid zones that can go as far as to almost sterilization of these soils. In this research, it is proposed to undertake the study on catabolic profiles of cultivable microbial communities of forest soils in western Algeria along a latitudinal gradient in some sampled surface horizons of the three zones, namely Tlemcen, Saida and Naama. Like most of soils in semiarid and arid zones, they are soils with low content in organic matter and in clay, and most often the sandy to the sand-like texture. 158 Borsali Amine Habib et al. The analysis of the catabolic profiles was carried out in five study plots of about 400 m each selected in each study area, making a total of fifteen plots for the three zones (Tlemcen, Saida and Naama). On each plot, five samples of soil were taken randomly between 0 and 15 cm of depth. Catabolic profiles were determined following the modified protocol of Garland and Mills (1991). The present research study show that it is in the Tlemcen zone, considered as subhumid, that a greater diversity and catabolic wealth were found; and more down towards the arid zone, more that wealth and diversity decrease to a critical level for the Naama zone. The results showed that there is a significant effect of the bioclimatic stage on the soil biological wealth and diversity.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"64 1","pages":"157-169"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81410910","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}

The aim of this study was to evaluate the effect of silver and ZnO NPs on Sinorhizobium meliloti and alfalfa symbiosis. S. meliloti bacteria were isolated from the alfalfa root nodules. Minimum inhibitory concentrations (MIC) of NPs were determined by agar dilution method. The effects of NPs on nodulation were studied by plant infection test in Jensen-nitrogen free agar medium. The gene expression of nitrogen fixation (nif gene) was evaluated in the presence of NPs by Real Time PCR. It was found that in the presence of NPs, the total length of treated plants and the number of nodules were decreased by increasing the concentration of NPs (1.25 to 10 μg/ml of AgNPs and 12.5 to 100 mg/ml of ZnO NPs) compared to the control plants (p ≤ 0.05). nif gene expression was decreased in the presence of sub MIC concentration of NPs.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"56 1","pages":"83-90"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77473791","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}
