Effects Of Short-Term Pesticides Exposure On Swimming Behavior, Tissue Morphology, Oxidative-Nitrative Stress, Antioxidant Expression, And Cellular Apoptosis In Kidneys Of Goldfish, Esmirna Cantú
Theses and Dissertations
The prevalence of pesticides in the aquatic environment continues to increase due to anthropogenic activities and poses a threat to aquatic organisms. The aim of this study was to determine the short-term exposure (one-week) of pesticide mixtures (metolachlor, linuron, isoproturon, tebucanazole, alconifen, atrazine, pendimethalin; azinphos-methyl) on swimming behaviors, kidney morphology, and expression of nitrotyrosine protein (NTP), dinitrophenyl protein (DNP), superoxide dismutase (SOD), catalase (CAT), renin, and cellular apoptosis in goldfish (Carassius auratus). Results indicated that both low- and high-dose pesticide mixtures decreased the distance swimming behavior. Histological analysis showed pesticide exposure alters kidney morphology. DNP, NTP, and renin expressions, and …

Background: Diabetes is a disease characterized by the increase in the serum glucose concentration. Therefore, this glucose excess shunts into the hexosamine biosynthetic pathway producing UDP-GlcNAc, which can be transfer to serine residues and modify the activity of different proteins, including contractile proteins in cardiomyocytes, decreasing their function. Here we show the effect of IGF-1 treatment on this posttranslational modification.
Methods: H9c2 cell line were cultured in DMEM media, 10% FBS, at 80% of confluence. Cells were incubated in high-glucose (30 mM) in the presence or absence of 10 µmol/L of IGF-1 (HG and HG+IGF-1). As control groups, we used …

Introduction: Type 2 diabetes (T2D), the fastest growing pandemic, is typically accompanied by vascular complications. A central hallmark of both T2D and vascular disease is insulin resistance which causes impaired glucose transport and vasoconstriction concomitantly. Those with cardiometabolic disease display greater variation in central hemodynamics and arterial elasticity, both potent predictors of cardiovascular morbidity and mortality, which may be exacerbated by concomitant hyperglycemia and hyperinsulinemia during glucose testing. Thus, elucidating central and arterial responses to glucose testing in those with T2D may identify acute vascular pathophysiologies triggered by oral glucose loading.
Aim: This study compared hemodynamics and arterial stiffness to …
