Effects of obesity on endothelium-dependent reactivity during acute nitric oxide synthase inhibition: modulatory role of endothelin.

Only registered users can translate articles

This study investigated vascular reactivity in response to acetylcholine, in the presence of acute inhibition of nitric oxide synthase, in the carotid artery and aorta of obese C57Bl6/J mice fed on a high-fat diet for 30 weeks, and of control mice. A subgroup of obese animals was also treated with

Monoamine oxidase is a source of oxidative stress in obese patients with chronic inflammation 1.

Only registered users can translate articles

Obesity is an important preventable risk factor for morbidity and mortality from cardiometabolic disease. Oxidative stress (including in visceral adipose tissue) and chronic low-grade inflammation are the major underlying pathomechanisms. Monoamine oxidase (MAO) has recently emerged as an important

Improvement of thoracic aortic vasoreactivity by continuous and intermittent exercise in high-fat diet-induced obese rats.

Only registered users can translate articles

The aim of the present study was to explore the effects of continuous and intermittent exercise on the thoracic aortic vasoreactivity and free radical metabolism in rats fed with a high-fat diet (HD). Sprague-Dawley (SD) rats were randomly divided into four groups (n=8, each group): Conventional

Exendin-4 directly improves endothelial dysfunction in isolated aortas from obese rats through the cAMP or AMPK-eNOS pathways.

Only registered users can translate articles

OBJECTIVE To determine whether exendin-4 might directly improve endothelial dysfunction in aorta isolated from high-fat diet-induced obese rats. METHODS Wistar rats were randomly divided into control and obesity (OB) groups and fed. Vascular segments of obese rats were incubated in organ bath in the

[Color Doppler sonography of focal abdominal lesions].

Only registered users can translate articles

Color Doppler sonography (CDS--spectral, color and power), harmonic imaging techniques (THI, PHI), possibility of 3D analysis of picture, usage of contrast agents, have raised the values of ultrasound as a diagnostic method to a very high level. THI--non-linear gray scale modality, is based on the

Caloric restriction reverses high-fat diet-induced endothelial dysfunction and vascular superoxide production in C57Bl/6 mice.

Only registered users can translate articles

Obesity is frequently associated with endothelial dysfunction. We hypothesized that high-fat feeding dysregulates the balance between endothelial derived nitric oxide and superoxide formation. Furthermore, we examined whether caloric restriction could reverse the detrimental vascular effects related
