Impacts of dose and length of exposure to boldenone and stanazolol on enzymatic antioxidant systems, myeloperoxidase and NAGase activities, and glycogen and lactate levels in rat liver.

We investigated the adverse effects of the anabolic androgenic steroids (AAS) boldenone (BOL) and stanazolol (ST) on the enzymatic antioxidant systems of the rat liver. Male Wistar rats were divided in three protocols (P): PI, 5 mg/kg BOL or ST once a week for 4 weeks; PII, 2.5 mg/kg BOL or ST once a week for 8 weeks; PIII, 1.

Resveratrol as a Therapy to Restore Neurogliogenesis of Neural Progenitor Cells Infected by Toxoplasma gondii.

The intracellular protozoan Toxoplasma gondii may cause congenital toxoplasmosis and serious brain damage in fetus. However, the underlying mechanism of neuropathogenesis in brain toxoplasmosis remains unclear. For this study, neural progenitor cells (NPCs) were obtained from embryo telencephalons (embryonic day 13) and induced to proliferation in the presence of growth factors (GFs).

Cattle naturally infected by Eurytrema coelomaticum: Relation between adenosine deaminase activity and zinc levels.

The enzyme adenosine deaminase (ADA) is critical for modulating the immune system, and in the presence of zinc, its activity is catalyzed. The aim of this study was to evaluate the ADA activity in pancreas of cattle naturally infected by Eurytrema coelomaticum in relation to the results of zinc levels, pathological findings and parasite load. For this study 51 slaughtered cattle were used.

Supplementation with copper edetate in control of Haemonchus contortus of sheep, and its effect on cholinesterase's and superoxide dismutase activities.

The aim of this study was to evaluate the effect of copper edetate on biochemical parameters, oxidative profile, cholinesterase's activities, as well as its capacity to control gastrointestinal parasites in infected sheep. Thus, Lacaune sheep (n = 18) infected by Haemonchus contortus were used and divided into three groups of six animal each: the group A was composed of untreated animals (the control group), the group B was formed by animals treated with 0.3 mg/kg of copper edetate, and the group C was composed of animals treated with 0.

Social Jetlag Among Night Workers is Negatively Associated with the Frequency of Moderate or Vigorous Physical Activity and with Energy Expenditure Related to Physical Activity.

This cross-sectional study analyzed the association between physical activity (PA) and social jetlag (SJL) among shift workers. We evaluated 423 employees, aged between 18 and 60 years, who worked in a poultry-processing company in Brazil. Physical activity levels (PAL) were determined by the short form of the International Physical Activity Questionnaire (IPAQ-SF).

Hepatic cholinesterase of laying hens naturally infected by Salmonella Gallinarum (fowl typhoid).

Salmonella is a facultative intracellular pathogen that may cause foodborne gastroenteritis in humans and animals consisting of over 2000 serovars. The serovar Salmonella Gallinarum is an important worldwide pathogen of poultry. However, little is known on the mechanisms of pathogenesis of Salmonella in chickens.

Imidocarb dipropionate in the treatment of Anaplasma marginale in cattle: Effects on enzymes of the antioxidant, cholinergic, and adenosinergic systems.

Anaplasmosis is a worldwide hemolytic disease in cattle caused by a gram-negative obligatory intracellular bacterium, characterized by anemia and jaundice. Among the treatments used for anaplasmosis is a drug called imidocarb dipropionate, also indicated as an immunomodulator agent. However, it causes side effects associated with increased levels of acetylcholine.
