Prevalence of Polymorphism and Post-Training Expression of ACTN3 (R/X) and ACE (I/D) Genes in CrossFit Athletes.

Background: CrossFit is known as a functional fitness training high-intensity exercise to improve physical performance. The most studied polymorphisms are the ACTN3 R577X gene, known for speed, power, and strength, and ACE I/D, related to endurance and strength. The present investigation analyzed the effects of training on ACTN3 and ACE gene expression in CrossFit athletes for 12 weeks.

[ANTHROPOMETRIC INDICES AND ITS RELATIONSHIP WITH BIOCHEMICAL MARKERS IN WOMEN].

Objective: to analyze the relationship between anthropometric indices of adiposity and some blood markers of risk for development of metabolic disease in healthy women with different body weight.

Method: participated 23 women of 21.0 ± 2.

[Factors affecting oxidative damage in obese children: an exploratory study].

Introduction: Obesity is a metabolic disorder that creates oxidizing conditions, which can generate high levels of physiological stress as well as a disturbance in the state of redox cell known as Oxidative Stress.

Objective: To examine the association between the damage on chromosomal DNA and the total antioxidant capacity (TAC) in obese children with severe obesity.

Methods: Participants were 11 children with a mean age and body mass index of 9.

A single dose of caffeic acid phenethyl ester prevents initiation in a medium-term rat hepatocarcinogenesis model.

Aim: To study of the effect of caffeic acid phenethyl ester (CAPE) on the initiation period in a medium-term assay of hepatocarcinogenesis.

Methods: Male Wistar rats were subjected to a carcinogenic treatment (CT) and sacrificed at 25th d; altered hepatic foci (AHF) were generated efficiently. To a second group of rats a single 20 mg/kg doses of CAPE was given 12 h before initiation with CT and were sacrificed at 25th d.
