Green Tea Infusion Ameliorates Histological Damages in Testis and Epididymis of Diabetic Rats.

Green tea is a popular drink used for therapeutic purposes to mitigate the consequences of diabetes. In this study, we aimed at evaluating the potential of green tea infusion to ameliorate structural and enzymatic damages caused by hyperglycemia in the testis and epididymis of Wistar rats. For that, nondiabetic and streptozotocin-induced diabetic rats (negative control and diabetes control, respectively) received 0.

Green tea infusion prevents diabetic nephropathy aggravation in recent-onset type 1 diabetes regardless of glycemic control.

Ethnopharmacological Relevance: Green tea, traditionally used as antidiabetic medicine, positively affects the diabetic nephropathy. It was assumed that these beneficial effects were due to the hypoglycemiant capacity of the tea, wich reduces the glycemic overload and, consequently, the advanced glycation end products rate and oxidative damage. However, these results are still controversial, since tea is not always able to exert a hypoglycemic action, as demonstrated by previous studies.

Analysis of motor performance and histomorphometry of skeletal muscles of rats exercised after cerebral ischemia.

Introduction: Cerebral ischemia causes muscle atrophy and motor incoordination in animals, impairing motor performance.

Objective: Thus, the objective of the present study was to analyze the motor performance and histomorphometry of the biceps brachii, soleus, and anterior tibialis muscles of rats submitted to a treadmill training program after induction of cerebral ischemia by the transient occlusion of the middle cerebral artery (MCAO).

Materials And Methods: To do so, twenty-four 30-day-old Wistar rats were utilized.

Could biological tissue preservation methods change chemical elements proportion measured by energy dispersive X-ray spectroscopy?

Energy dispersive X-ray spectroscopy (EDS) is a powerful technical tool used in the biomedical field to investigate the proportion of chemical elements of interest in research, such as heavy metal bioaccumulation and the enzymatic cofactors and nanoparticle therapy in various pathologies. However, the correct evaluation of the proportion of the elements is subject to some factors, including the method of sample preservation. In this study, we seek to investigate the effect of biological tissue preservation methods on the proportion of chemical elements obtained by the EDS methodology.

Swimming training attenuates the morphological reorganization of the myocardium and local inflammation in the left ventricle of growing rats with untreated experimental diabetes.

Diabetic cardiomyopathy is associated with cardiac remodeling, myocardial dysfunction, low-grade inflammation, and reduced cardiac adiponectin in patients with type 1 diabetes mellitus (T1DM). Alternatively, physical exercise is an important strategy for the management of diabetes. This study aimed to investigate the influence of low-intensity swimming training in cardiac cytokines, structural remodeling, and cardiomyocyte contractile dysfunction in growing rats with untreated experimental DM.

Effect of bark extract of Bathysa cuspidata on hepatic oxidative damage and blood glucose kinetics in rats exposed to paraquat.

This study investigated the effect of bark extract of Bathysa cuspidata on hepatic oxidative damage and blood glucose kinetics in rats exposed to paraquat. Wistar rats were exposed to a single dose of paraquat (30 mg/kg, i.p.

Grape extract and α-Tocopherol effect in cardiovascular disease model of Apo E -/- Mice.

Purpose: To verify the effect of consumption of grape extract isolated or combined with α-tocopherol supplementation on atherosclerosis model with Apo E -/- mice.

Methods: After six weeks of atherogenic diet, Apo E -/- mice were divided into the following groups: Control, Grape, Tocopherol and Grape plus Tocopherol. The treatment progressed for 11 weeks when animals were submitted to euthanasia.
