The Effect of Acute Physical Exercise on Natural Killer Cells Populations and Cytokine Levels in Healthy Women.

Physical exercise generates a systemic response in the immune system. It has been observed that cell populations respond to exercise stimuli, especially Natural Killer cells, whose number increase within minutes of starting physical exertion. This study aimed to evaluate the acute effect of moderate- and high-intensity exercise on immunological markers in healthy women.

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.

Assessment of Physical Activity in Adults: A Review of Validated Questionnaires From a Nutritionist's Point of View.

Physical activity (PA) is a component of total energy expenditure. PA and PA energy expenditure (PAEE) can be estimated by objective techniques (OTs). However, the use of questionnaires is frequent in clinical settings and epidemiological studies.

Prepregnancy Obesity, Maternal Dietary Intake, and Oxidative Stress Biomarkers in the Fetomaternal Unit.

Background: Obesity and pregnancy increase levels of maternal oxidative stress (OS). However, little is known about the maternal, placental, and neonatal OS status.

Objective: To analyze the relation between prepregnancy obesity and the expression of OS markers and antioxidant capacity in the fetomaternal unit and their association with dietary intake.

[Moderate exercise and intake of either high or low glycemic index carbohydrates in sedentary women].

Objective: To analyze changes in blood glucose, insulin and triglyceride concentrations in relation to a moderate aerobic exercise in sedentary women of different body weight, exposed to either a high or low glycemic index carbohydrates diet. DISEñO: Cross-over type. SITE: Research was performed in the Exercise Physiology Laboratory at Facultad de Ciencias de la Cultura Física, Universidad Autónoma de Chihuahua, México.

[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.

Co-carcinogenic effect of cyclohexanol on the development of preneoplastic lesions in a rat hepatocarcinogenesis model.

Cyclohexanol is a basic industrial chemical widely used because of its versatility as an industrial solvent. No studies have been conducted to evaluate the carcinogenic/co-carcinogenic hazards associated with cyclohexanol exposure. In male Fisher 344 rats liver preneoplastic lesions were induced by N-nitrosodiethylamine (150 mg/Kg) i.

Chemoprotective effect of caffeic acid phenethyl ester on promotion in a medium-term rat hepatocarcinogenesis assay.

Caffeic acid phenethyl ester (CAPE), a natural honeybee product exhibits a spectrum of biological activities including anti-microbial, anti-inflammatory, antioxidant and anti-tumoral actions. CAPE is also chemopreventive against intestinal, colon and skin cancer. Our aim was to extend the study of its chemoprotective features to the promotion of hepatocarcinogenesis.
