Methods: Retrospective cohort study of extrapulmonary tuberculosis patients (military personnel) admitted to the Armed Forces Pulmonary Diseases Hospital (AFPHD). An analysis has been conducted based on the medical records of the servicemen discharged from the Army due to extrapulmonary tuberculosis, the features of the epidemic process have been studied and the results have been assessed. Results: The incidence of disease by age group, duration of service and seasonal frequency have been examined on the basis of the medical records of 18 to 49 year old military personnel diagnosed with extrapulmonary tuberculosis in the Armed Forces Pulmonary Diseases Hospital(AFPHD). The conscripts were grouped into three age bands (18-21, 22-29, 30-49), the duration of service was divided into three groups, with the first 0-3 months, 3-6 months and more than 6 months of military service. Conclusion: This is the first study of extrapulmonary tuberculosis in the Armed Forces of the Republic of Azerbaijan and showed increasing trends in noti10 S. B. Ahmedov and E. S.

Extrapulmonary tuberculosis have been observed among the personnel of the Armed Forces of the Republic of Azerbaijan in all years involved in the study.

The present research aimed to identify the main internal criticalities and evaluate the possibility of correction, also considering the technical and economic aspects and the constraints of the firm layout. The research included a phase of cost analysis and benefit estimation, considering different possible scenarios. In the evaluation of the hypothetical investment, not only the purely economic aspects were taken into consideration, but also the qualitative ones. Results showed a potential excellent return on investment in the new business process, if it is accompanied by a progressive growth in indirect turnover due to new consulting activities induced by the reorganization of the laboratory. The study also shows that, in the event of the development of a turnover induced by the new multi-residual analysis activity, the investment has the potential to achieve more than satisfactory returns. To achieve these results, it was necessary to reorganize and optimize internal processes, based on a study of the internal production layout and how this affects current production both in terms of integration and for the acquisition of new highly qualified skills not present to date.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90194105","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}

In responses to abiotic stresses such as heat, oxidative stress and nutrient limitations yeast cells activates trehalose biosynthesis and accumulates trehalose as stress protectant agent. Glycogen is also accumulated within the yeast cells as reserve carbohydrates. Trehalose and glycogen metabolism are well characterized in S. cerevisiae, but there is a limited information on these carbohydrates in candida species. In this study, we have analyzed the stress-dependent accumulation patterns of trehalose and glycogen in C. albicans as a pathogenic yeast and C. rugosa as an industrial yeast. Our results indicate that there are clear differences in storage carbohydrate metabolism between these two yeasts species. Basal levels of glycogen in C. rugosa 62 Hülya Karaca Gençer et al. is higher than the C. albicans glycogen content when these yeasts grown in normal conditions. However, when these yeasts subjected to stress inducing conditions, both trehalose and glycogen biosynthesis activated and rapidly accumulated within these yeast cells. Nonetheless, stress dependent activation of trehalose and glycogen biosynthesis in C. rugosa is much higher than the C. albicans. In addition, exposure of these yeast species to different abiotic stresses also resulted in activation of TPS1 and GSY1 gene transcription. The differences in trehalose biosynthesis and TPS1 transcript levels indicates that reserve carbohydrate metabolism is differentially regulated in C albicans and C. rugosa.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"1 1","pages":"61-77"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82490132","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}

Present research aims at studying the importance of Pro72Arg and Arg249Ser of TP53 gene in success of IVF-ET. One hundred and fifty infertile women with unsuccessful IVF-ET history and 210 women with successful IVF-ET history were studied using polymerase chain reaction– restriction fragment length polymorphism (PCR–RFLP) and amplification refractory mutation system (ARMS-PCR). The P53 codon 249 Ser allele was found to be over-represented in patients (p=0.0001; Odds Ratio=3.407; 95% CI; 1.81-6.38). In this study, the distribution of the genotype at codon 72 in the unsuccessful IVF women was not different from the controls (p=0.5). In conclusion, despite the P53 codon 249 Ser allele appearing to be associated with a trend of increased risk of IVF failure, P53 Pro72Arg gene polymorphism might not be a useful marker for prediction of IVF-ET outcome. However, in order to confirm the results, the studies are recommended to be conducted in larger populations.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"24 1","pages":"33-44"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78168085","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}

In this article, a novel 46 Khan Bahadar Khan et al. technique has been introduced for OD detection and borderline extraction, which can be witnessed as a milestone in the advancement of a Computer-Assisted Diagnostic (CAD) framework for glaucoma detection in fundus photographs. A unique solution has been presented for removal of illuminated light spots due to refraction of camera light (so called fringe noise) on the edges of the retinal color images, which leads to false detection of OD. An intelligent non-uniform mixing of red and green channels is introduced for denoising of retinal photographs because of the dissimilar noise level in each channel. Template based matching technique is applied for OD localization of retinal image. The approach is thoroughly verified on openly accessible the DRIVE and the STARE datasets for OD detection and denoising of retinal images. This denoising technique greatly improved the accuracy of OD detection in contrast to other contending approaches.","PeriodicalId":7194,"journal":{"name":"Advanced Studies in Biology","volume":"26 1","pages":"45-59"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83244711","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}
