Increased NOX-dependent ROS production and proportionally enhanced antioxidant response in white adipose tissue of male rats.

Objective: This study aimed to investigate the redox balance in subcutaneous and retroperitoneal fat pads of male and female Wistar rats.

Materials And Methods: The study analyzed the activity and gene expression of the antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase, along with the production of NADPH oxidases dependent on HO and gene expression of NOX1, NOX2, and NOX4.

Results: The retroperitoneal fat pad in males compared with females had greater NOX2 and NOX4 expression, along with higher superoxide dismutase activity.

Phytoceutical isoquercitrin and ethanolic extracts from pequi (Caryocar coriaceum Wittm) reverse alcohol withdrawal-induced anxiety in adult zebrafish (Danio rerio).

Pharmacotherapy in Alcohol Withdrawal Syndrome (AWS), which is a mental disorder, generally involves benzodiazepines due to their action via GABA, but their side effects, such as excessive sedation, mental confusion and risk of dependence, are considerable. It is important to investigate the anxiolytic potential of plants such as Caryocar coriaceum, due to the presence of secondary metabolic compounds, such as isoquercitrin, capable of promoting the reduction of anxiety during AWS. We evaluated the anxiolytic-like potential of ethanolic extracts from the leaves (EEPL) and pulp (EEPP) of C.

Evaluation of the relationship between nutritional status, levels of physical activity and physical strength in adolescents.

Background & Aims: The study aimed at evaluating the relationship among anthropometric measurements, levels of physical activity and physical fitness in schoolchildren.

Methods: A cross-sectional study was carried out in public schools, with 173 adolescents from 10 to 17 years of age. Socioeconomic data were obtained by a structured questionnaire.

Effects of consumption of acerola, cashew and guava by-products on adiposity and redox homeostasis of adipose tissue in obese rats.

Background: Fruit by-products contain phytochemicals, fibers and other components that can improve the redox imbalance of obesity.

Objective: The objective was to evaluate the effects of consumption of by-products of acerola, cashew and guava on the adiposity and redox homeostasis of adipose tissue in obese rats.

Methods: The animals were separated into 5 groups, control (CTL), high fat (HF), HF supplemented with acerola (HFA), cashew (HFC) and guava (HFG).

Anabolic androgenic steroid-induced hypogonadism, a reversible condition in male individuals? A systematic review.

The anabolic-androgenic steroids (AAS) are clinically used as an androgen replacement, in hypogonadism treatment, to induce puberty, and also in the treatment of chronic degenerative diseases. The AAS use out of clinical context is becoming massively, being used merely for aesthetic reasons. AAS abuse may cause severe disarrangement on the HPG axis and generate a significant decrease in testosterone synthesis and secretion by the testes.

High-dose Nandrolone Decanoate induces oxidative stress and inflammation in retroperitoneal adipose tissue of male rats.

The non-therapeutic use of the androgenic anabolic steroid Nandrolone Decanoate is popular due to its effects on physical performance and body composition, especially for its lipolytic and anabolic effects associated. However, high doses of such drugs are often associated with a series of pathologies related to unbalanced redox homeostasis, which, in turn, can be linked to inflammation. The oxidative stress onset could deregulate the secretion of cytokines, evidencing a dysfunctional adipocyte.
