Histological investigation of experimentally induced diabetes effects on the distribution of transforming growth factor (TGF beta), nuclear factor kappa b (Nf-KB), heat schock 90 beta (Hsp beta) and E-cadherin proteins in testicular tissue

Int. j. morphol; 39 (1), 2021
SUMMARY: Diabetes is a metabolic disorder characterized by high blood sugar levels and it causes complications in many systems, including the reproductive system. As a result of diabetic conditions, one of the mechanisms that can cause repression of reproductive activity is testicular oxidant stress. The...

Role of adiponectin in diabetes myocardial ischemia-reperfusion injury and ischemic postconditioning

Acta cir. bras; 35 (1), 2020
Abstract Purpose Patients with diabetes are vulnerable to myocardial I/R (ischaemia/reperfusion) injury, but are not responsive to IPO (ischaemic post-conditioning). We hypothesized that decreased cardiac Adiponectin (APN) is responsible for the loss of diabetic heart sensitivity to IPO cardioprotecton...

GDF11 ameliorated myocardial ischemia reperfusion injury by antioxidant stress and up-regulating autophagy in STZ-induced type 1 diabetic rats

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To investigate whether GDF11 ameliorates myocardial ischemia reperfusion (MIR) injury in diabetic rats and explore the underlying mechanisms. Methods: Diabetic and non-diabetic rats subjected to MIR (30 min of coronary artery occlusion followed by 120 min of reperfusion) with/without ...

Expression of myo-inositol cotransporters in the sciatic nerve and dorsal root ganglia in experimental diabetes

Braz. j. med. biol. res; 52 (6), 2019
The transport of myo-inositol is the main mechanism for the maintenance of its high intracellular levels. We aimed to measure the mRNA and protein levels of myo-inositol cotransporters in the sciatic nerve (SN) and dorsal root ganglia (DRG) during experimental diabetes. Streptozotocin-induced (STZ; 4, 8,...

A curcumin derivative J147 ameliorates diabetic peripheral neuropathy in streptozotocin (STZ)-induced DPN rat models through negative regulation AMPK on TRPA1

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To investigate the specific molecular mechanisms and effects of curcumin derivative J147 on diabetic peripheral neuropathy (DPN). Methods: We constructed streptozotocin (STZ)-induced DPN rat models to detected mechanical withdrawal threshold (MWT) in vivo using Von Frey filaments. I...

Effect of melatonin on antioxidant capacity, ınflammation and apoptotic cell death in lung tissue of diabetic rats

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate the effects of melatonin on antioxidant capacity, inflammation and apoptotic cell death (through expression of cleaved-caspase 3) in lung tissue samples of diabetic rats. Methods: Thirty male Sprague-Dawley rats were randomly divided into three groups. Group 1 (control...

Effects on alveolar bone of diabetes mellitus induced by streptozotocin in rats: histopathologic and immunohistochemical study

Int. j. morphol; 36 (1), 2018
SUMMARY: The purpose of this study was to investigate effects of diabetes mellitus (DM) on the alveolar bone with histopathological and immunohistochemical methods. Wistar rats were divided into two groups, control and diabetes group. Control group was fed standard rat chow and drinking water for 8 weeks...

Beetle (Ulomoides dermestoides) fat improves diabetes: effect on liver and pancreatic architecture and on PPARgamma expression

Braz. j. med. biol. res; 51 (6), 2018
Ulomoides dermestoides is a beetle traditionally consumed to treat diabetes. In this study, we performed a composition analysis of U. dermestoides to obtain the principal fractions, which were used to assess the effect on glycemia, liver and pancreatic architecture, and PPARγ and GLUT4 expression. N...

MAFB mediates the therapeutic effect of sleeve gastrectomy for obese diabetes mellitus by activation of FXR expression

Braz. j. med. biol. res; 51 (7), 2018
Farnesoid X receptor (FXR) and related pathways are involved in the therapeutic effect of sleeve gastrectomy for overweight or obese patients with diabetes mellitus. This study aimed to investigate the mechanism of FXR expression regulation during the surgical treatment of obese diabetes mellitus by slee...

Physical training reverses changes in hepatic mitochondrial diameter of Alloxan-induced diabetic rats

Einstein (Säo Paulo); 16 (3), 2018
ABSTRACT Objective To investigate the effects of physical training on metabolic and morphological parameters of diabetic rats. Methods Wistar rats were randomized into four groups: sedentary control, trained control, sedentary diabetic and trained diabetic. Diabetes mellitus was induced by Alloxan (3...
