It is widely used as part of polycarbonate plastics and epoxy resins, from which reusable plastic bottles, food boxes and some medical equipment are made. It is also used to coat the inner layer of the cans. Previous studies have shown that BPA contributes to many chronic diseases in the human body, such as kidney disease - diabetic nephropathy.

The Incidence of Complications in Patients with Diabetes Mellitus
Korytenská, Kristýna ; Pavlíková, Pavla (advisor) ; Hrdličková, Renáta (referee)
1 Abstract This thesis deals with the occurrence of complications in patients with diabetes mellitus. The aim of this bachelor thesis is determine which acute and chronic complications prevail in relation to gender, type of diabetes and duration of diabetes. The thesis is divided into theoretical and practical part. In the theoretical part of the thesis I described themselves diabetes mellitus, types of diabetes mellitus, acute complications and chronic complications. Among the acute complications include hyperglycemia and hypoglycemia. Chronic complications are divided into specific and nonspecific. In the empirical part, I followed the incidence of complications. I realized quantitative research using questionnaires. The questionnaire was own of design. Participated in this research 78 respondents who were acquired in diabetes clinics. I divided respondents into subsequent categories: women with type I diabetes, women with type II diabetes, men with type I diabetes and men with type II diabetes. The thesis results that, overall acute and chronic complications suffered total 41 % of respondents. The most common complication of acute hyperglycemia reported 25.6 % of respondents. The most common complications were chronic diabetic neuropathy and diabetic retinopathy, each with 6.5% of respondents. Keywords:...

Gene expression profiling in diabetic nephropathy
Nepomucká, Kateřina ; Pavlínková, Gabriela (advisor) ; Černá, Věra (referee)
Diabetic nephropathy (DN) is induced by both type 1 and type 2 diabetes mellitus and it is one of the most serious complications associated with diabetes. Despite increasing incidence of diabetes, the exact pathogenesis remains unclear. Hypoxia is regarded as a crucial factor for the progression of renal disease. The responses to hypoxia are mainly regulated by hypoxia-inducible factor 1 (HIF1). We thus considered a possible link between HIF1-regulated pathways and the susceptibility to DN and the disease progression. We hypothesize that the exposure of renal tissue to diabetes causes gene expression changes in HIF1-regulated pathway and the altered expression profile is decisive for the development of DN. Using mouse model, we analyzed cellular and molecular changes in HIF1 heterozygous-null (Hif1α+/- ) and wild type (wt) littermates exposed to diabetic environment. Our histological analysis showed early pathological changes associated with DN in both diabetic wt and Hif1α+/- compared to non-diabetic controls. The morphological analysis did not demonstrate the effect of Hif1α+/- genotype in comparison to wt. For our molecular analysis with qRT-PCR method, we selected several genes, which were previously associated with pathological processes in kidney diseases. We identified statistically...
