Sitagliptin treatment prevented pancreatic lesions evolution in a rat modelo f ...

Background: This study aimed to elucidate mechanisms underlying the protective effects of sitagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, against pancreatic lesions, in an animal model of T2DM. Methods: Male obese diabetic ZDF (fa/fa) rats, 20-weeks-old, were treated with vehicle or sitagliptin (10mg/kg BW/day) for 6 weeks, and compared with lean control littermates (n=8/each). Biochemical parameters ...

Spatial memory impairments in a prediabetic rat model

Diabetes is associated with an increased risk for brain disorders, namely cognitive impairments associated with hippocampal dysfunction underlying diabetic encephalopathy. However, the impact of a prediabetic state on cognitive function is unknown. Therefore, we now investigated whether spatial learning and memory deficits and the underlying hippocampal dysfunction were already present in a prediabetic animal m...

Chemopreventive Efficacy of Atorvastatin against Nitrosamine-Induced Rat Bladde...

To investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) Control: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinogen were given betw...

Presence of Kimmelstiel-Wilson like lesions in canine renal faillure

Background: Nodular increases in mesangial matrix is the definition of Kimmelstiel-Wilson (K-W) lesions. In man, focal mesangiolyses and K-W nodules were positively associated with diabetes, proteinuria and hyalinization of afferent and efferent arterioles. Although, nodular sclerotic lesions may also occur in the absence of diabetic nephropathy and are clinically related to hypertension, smoking, hypercholeste...

Sitagliptin delays progression of renal lesions in a rodent model of type 2 dia...

Expression of genes encoding extracellular matrix macromolecules and metallopro...

Avian tibial dyschondroplasia (TD) is a skeletal disease characterized by disruption of endochondral bone formation. The aim of this study was to determine the expression of extracellular matrix (ECM) macromolecules and ECM-degrading enzymes [matrix metalloproteinases (MMPs)] in the growth plates of normal and TD-affected 3-week-old broiler chicks (Cobb strain). Protein levels were analyzed by immunoblotting an...

Pancreatic lesions and metabolic aggravation are prevented by low doses of sita...

Introduction: The management of type 2 diabetes is designed to reduce disease-related complications and improve long-term outcomes. Inhibition of dipeptidyl peptidase-4 (DPP-4) activity by sitagliptin has been shown to improve glycaemic control in patients with type 2 diabetes Mellitus (T2DM) by prolonging the actions of incretin hormones, but the real impact of low-dose sitagliptin treatment on cardiometabolic...

Renal structure modification in an animal model of type 2 diabetes with aging: ...

Background and aims: The Zucker Diabetic Fatty (ZDF-fa/fa) rat is one of the most used models for the study of type 2 diabetes (T2DM). Characterization of renal morphology in this model may provide useful insights into the mechanism of diabetic nephropathy progression. The purpose of the present study was to determine renal morphology, identify and characterize renal dysfunction complications such as hydronephr...
