Dietary Egg White Hydrolysate Prevents Male Reproductive Dysfunction after Long-Term Exposure to Aluminum in Rats.

Aluminum (Al) is a non-essential metal omnipresent in human life and is considered an environmental toxicant. Al increases reactive oxygen production and triggers immune responses, contributing to chronic systemic inflammation development. Here, we have tested whether an egg white hydrolysate (EWH) with potential bioactive properties can protect against changes in reproductive function in rats exposed to long-term Al dietary levels at high and low doses.

Oxidative Stress Induced by 30 Days of Mercury Exposure Accelerates Hypertension Development in Prehypertensive Young SHRs.

Mercury is considered a risk factor for the development of hypertension and other cardiovascular diseases. We investigated whether the effects of mercury exposure on haemodynamic parameters of young Wistar rats and prehypertensive SHRs might alter the time course of hypertension development. Young (4 weeks) male Wistar rats and SHRs were randomly assigned to four groups: untreated Wistar rats (Wistar Ct), Wistar rats exposed to mercury chloride for 30 days (Wistar Hg), untreated SHRs (SHR Ct) and SHRs exposed to mercury chloride (SHR Hg) for 30 days.

ROS Suppression by Egg White Hydrolysate in DOCA-Salt Rats-An Alternative Tool against Vascular Dysfunction in Severe Hypertension.

This study aimed to evaluate the potential for lowering blood pressure and beneficial effects on mesenteric resistance arteries (MRA) and conductance vessels (aorta) produced by dietary supplementation of an egg white hydrolysate (EWH) in rats with severe hypertension induced by deoxycorticosterone plus salt treatment (DOCA-salt), as well as the underlying mechanisms involved. The DOCA-salt model presented higher blood pressure, which was significantly reduced by EWH. The impaired acetylcholine-induced relaxation and eNOS expression observed in MRA and aorta from DOCA-salt rats was ameliorated by EWH.

Immunonutrition in ovarian cancer: clinical and immunological impact?

Objective: Malnutrition is frequent in ovarian cancer (OC) patients and may compromise post-operative outcomes. The aim of this study is to evaluate the impact of pre-operative immunonutrition on the surgical outcome of OC patients, and on their nutritional, inflammatory and peripheral blood immune status.

Methods: A prospective study was performed between September 2016 and April 2020.

The History of the Post-Graduate Medical and Nursing Officers (PGMNO) course in the British Army.

Military medicine has been evolving for over 5000 years of recorded civilisation and conflict. The Army Medical Services performed poorly during the Crimean War and the British Army introduced a professional training course for medical officers in 1860. The Army Medical School and the predecessor of today's Post-Graduate Medical and Nursing Officers (PGMNO) course have had to adapt to changes in British foreign policy and military requirements.

Copper exposure for 30 days at a daily dose twice the recommended increases blood pressure and cardiac contractility.

Unlabelled: Copper is an essential factor for the body's homeostasis. However, excess copper compromises organic functions.

Aims: We investigated the effects of copper exposure for 30 days on blood pressure (BP) and cardiac contractility and the putative involvement of nitric oxide (NO) and reactive oxygen species.

Chronic mercury exposure induces oxidative stress in female rats by endothelial nitric oxide synthase uncoupling and cyclooxygenase-2 activation, without affecting oestrogen receptor function.

Mercury has been shown to be a significant health risk factor and is positively associated with cardiovascular diseases. Evidence reveals that men are more likely to develop cardiovascular diseases than women during reproductive age. However, the effects of mercury in females remain poorly investigated, despite the finding that female hormones demonstrate a cardioprotective role.

Post-weaning protein malnutrition induces myocardial dysfunction associated with oxidative stress and altered calcium handling proteins in adult rats.

Hypercaloric low-protein diet may lead to a state of malnutrition found in the low-income population of Northeastern Brazil. Although malnutrition during critical periods in the early life is associated with cardiovascular diseases in adulthood, the mechanisms of cardiac dysfunction are still unclear. Here we studied the effects of post-weaning malnutrition due to low protein intake induced by a regional basic diet on the cardiac contractility of young adult rats.

Chronic Low-Level Lead Exposure Increases Mesenteric Vascular Reactivity: Role of Cyclooxygenase-2-Derived Prostanoids.

Lead (Pb) exposure causes hazardous effects as hypertension and other cardiovascular diseases. We evaluated whether chronic Pb exposure alters the peripheral vascular resistance measuring the vascular reactivity of mesenteric resistance arteries in rats to identify the underlying mechanisms that are associated to the development of Pb-induced hypertension. Mesenteric resistance arteries from lead-treated and untreated Wistar rats (1st dose: 10 μg/100 g; subsequent doses: 0.

Changes in the renal function after acute mercuric chloride exposure in the rat are associated with renal vascular endothelial dysfunction and proximal tubule NHE3 inhibition.

Mercury is an environmental pollutant and a threat to human health. Mercuric chloride (HgCl)-induced acute renal failure has been described by several reports, but the mechanisms of renal dysfunction remain elusive. This study tested the hypothesis that HgCl directly impairs renal vascular reactivity.

Lead and mercury 28 day exposure at small concentrations reduces smooth muscle relaxation by decreasing cGMP.

Cardiovascular diseases are among the main causes of mortality in the world. There is evidence of cardiovascular harm after exposure to low lead or mercury concentrations, but the effects of chronic exposure to the association of low doses of these toxic metals are still unknown. This work evaluated after 4 weeks, the association effects of low concentrations of lead and mercury on blood pressure and vascular resistance reactivity.
