The Effect of High-Salt Diet on Oxidative Stress Production and Vascular Function in Tff3-/-/C57BL/6N Knockout and Wild Type (C57BL/6N) Mice.

Introduction: It is well documented that high-salt (HS) diet increases systemic and vascular oxidative stress in various animal models and in humans, leading to impairment of vascular reactivity. The present study examined the interaction of genotype and HS diet intake and the potential effects of oxidative stress - antioxidative system balance on the flow-induced dilation (FID) in pressurized carotid arteries of normotensive Tff3-/-/C57BL/6N knockout mice and their wild-type (WT) controls.

Methods: Male, ten-week-old transgenic Tff3-/-/C57BL/6N (Tff3-/-) knockout mice and WT/C57BL/6N (WT) (parental strain) healthy mice were divided in LS (0.

Knock-Out Mice with Altered Lipid Metabolism Exhibit a Lower Level of Inflammation following the Dietary Intake of Sodium Chloride for One Week.

A high salt intake causes hemodynamic changes and promotes immune response through cell activation and cytokine production, leading to pro-inflammatory conditions. Transgenic knock-out mice (TFF3ko) ( = 20) and wild-type mice (WT) ( = 20) were each divided into the (1) low-salt (LS) group and (2) high-salt (HS) group. Ten-week-old animals were fed with standard rodent chow (0.

Low-dose angiotensin II supplementation restores flow-induced dilation mechanisms in cerebral arteries of Sprague-Dawley rats on a high salt diet.

Objective: Salt-induced suppression of angiotensin II contributes to impaired endothelium-dependent vascular reactivity. The present study investigated the effect of chronic low-dose angiotensin II (ANG II) supplementation on the mechanisms of flow-induced dilation (FID) and oxidative stress at the cellular and molecular level in middle cerebral arteries (MCA) of male Sprague-Dawley rats fed high salt diet.

Methods: Rats (10 weeks old) were randomly assigned to a low salt diet group (0.

Effects of n-3 Polyunsaturated Fatty Acid-Enriched Hen Egg Consumption on the Inflammatory Biomarkers and Microvascular Function in Patients with Acute and Chronic Coronary Syndrome-A Randomized Study.

This study aimed to test the effect of n-3 polyunsaturated fatty acid (PUFA)-enriched hen egg consumption on serum lipid and free fatty acid profiles, inflammatory and oxidative stress biomarkers, and microvascular reactivity in patients with coronary artery disease (CAD). Forty CAD patients participated in this study. Of those, 20 patients had acute CAD (Ac-CAD), and 20 patients had chronic CAD (Ch-CAD).

Carnosine, Small but Mighty-Prospect of Use as Functional Ingredient for Functional Food Formulation.

Carnosine is a dipeptide synthesized in the body from β-alanine and L-histidine. It is found in high concentrations in the brain, muscle, and gastrointestinal tissues of humans and is present in all vertebrates. Carnosine has a number of beneficial antioxidant properties.

Angiotensin II type 1 receptor is involved in flow-induced vasomotor responses of isolated middle cerebral arteries: role of oxidative stress.

This study aimed to determine the mechanosensing role of angiotensin II type 1 receptor (ATR) in flow-induced dilation (FID) and oxidative stress production in middle cerebral arteries (MCA) of Sprague-Dawley rats. Eleven-week old, healthy male Sprague-Dawley rats on a standard diet were given the ATR blocker losartan (1 mg/mL) in drinking water (losartan group) or tap water (control group) ad libitum for 7 days. Blockade of ATR attenuated FID and acetylcholine-induced dilation was compared with control group.

Impact of High Salt Diet on Cerebral Vascular Function and Stroke in C57BL/6N Knockout and WT (C57BL/6N) Control Mice.

High salt (HS) dietary intake leads to impaired vascular endothelium-dependent responses to various physiological stimuli, some of which are mediated by arachidonic acid (AA) metabolites. Transgenic gene knockout mice (C57BL/6N) have changes in lipid metabolism which may affect vascular function and outcomes of stroke. We aimed to study the effects of one week of HS diet (4% NaCl) on vascular function and stroke induced by transient occlusion of middle cerebral artery in and wild type (WT/C57BL/6N) mice.
