Factors associated with accidents involving biological material among health professionals.

Introduction: Accidents with biological material and cuting/piercing instruments among health professionals have led to increased rates of hospital infection and subsequent patient contamination.

Objectives: To compare factors associated with accidents involving biological material among health workers.

Methods: This cross-sectional epidemiological study, conducted in 2019-2020, included 229 physicians and non-physicians.

Effect of ovariectomy and high-fat diet on the expression of estrogen receptors and adipose tissue metabolism in wistar rats.

This study addresses the increasing prevalence of obesity, especially among postmenopausal. Estrogen plays a crucial role in regulating adipose tissue in women, with its absence after menopause associated with metabolic complications. The study aimed to determine the lipolytic activity in different adipose tissue depots of ovariectomized rats submitted to a high-fat diet.

Arterial stiffness indices, pulse wave velocity and central systolic blood pressure, are able to discriminate between obese and non-obese children.

Unlabelled: The objectives of this study were to verify, first, if arterial stiffness indices can discriminate between obese and healthy children. Second, to evaluate arterial stiffness index predictors and hemodynamic parameters in obese children. Arterial stiffness indices evaluated were pulse wave velocity (PWV), central systolic blood pressure (SBPc), and central pulse pressure (PPc).

The effect of angiotensin-converting enzyme inhibition throughout a superovulation protocol in ewes.

Many studies identified new components of the renin–angiotensin system (RAS), such as Angiotensin-(1-7) [Ang-(1–7)] and Angiotensin-converting enzyme type 2 (ACE2), in mammalian ovaries.We previously showed Angiotensin-Converting Enzyme (ACE) inhibition, which increases the level of Ang-(1–7), stimulated ovarian estradiol output in ewe after estrous synchronization. Considering that Ang-(1–7) stimulates ovarian function and elevated estradiol before ovulation is associated with increased chance of achieving pregnancy, the present study investigated whether ACE inhibition throughout a superovulation protocol in ewe might improve ovulation outcome.

Sepsis induced by Staphylococcus aureus: participation of biomarkers in a murine model.

Background: This study aimed to evaluate the role of biomarkers in the pathophysiological process induced by a Staphylococcus aureus strain obtained in a hospital environment. For this, we intraperitoneally inoculated groups of male BALB/c mice with S. aureus, using a clinical isolate (CI) of S.

Natriuretic peptide system: a link between fat mass and cardiac hypertrophy and hypertension in fat-fed female rats.

The present study was designed to develop an animal model of hypertension and cardiac hypertrophy associated with obesity in female rats. Furthermore, we studied the involvement of the natriuretic peptide system in the mechanisms of these conditions. Obesity was induced in Wistar rats by a high fat diet and ovariectomy.
