Bisphenol A contamination in infant rats: molecular, structural, and physiological cardiovascular changes and the protective role of kefir.

The effects of bisphenol A (BPA) contamination on the cardiovascular function still are not clear. Here, we evaluated the vascular effects of BPA and the protective actions of kefir in infant rats. Animals (25 days old) were treated with BPA (100 μg/Kg/day) for 60 days (BPA group), or administered kefir (0.

Identification of new bioactive peptides from Kefir milk through proteopeptidomics: Bioprospection of antihypertensive molecules.

Kefir, a probiotic beverage prepared from fermented milk, has been associated with antihypertensive activity. However, the bioactive molecules responsible for this activity still remain unclear. Therefore, in this study we aim to evaluate the mechanisms of the antihypertensive effects of Kefir in the two-kidney one-clip hypertension model, and to bioprospect for bioactive peptides identified by proteomic methodologies.

Effects of Kefir on the Cardiac Autonomic Tones and Baroreflex Sensitivity in Spontaneously Hypertensive Rats.

Aims: It has been previously shown that the probiotic kefir (a symbiotic matrix containing acid bacteria and yeasts) attenuated the hypertension and the endothelial dysfunction in spontaneously hypertensive rats (SHR). In the present study, the effect of chronic administration of kefir on the cardiac autonomic control of heart rate (HR) and baroreflex sensitivity (BRS) in SHR was evaluated.

Methods: SHR were treated with kefir (0.

Chronic administration of the probiotic kefir improves the endothelial function in spontaneously hypertensive rats.

Background: The beverage obtained by fermentation of milk with kefir grains, a complex matrix containing acid bacteria and yeasts, has been shown to have beneficial effects in various diseases. However, its effects on hypertension and endothelial dysfunction are not yet clear. In this study, we evaluated the effects of kefir on endothelial cells and vascular responsiveness in spontaneously hypertensive rats (SHR).
