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.

Low Doses of G-CSF Prevent Cerebral Infarction and Maintain Muscle Strength in an Experimental Model of Global Ischemic Stroke.

Background: Stroke is a major cause of severe and long-term disability in adult individuals. Treatment of this disease is limited by the narrow therapeutic window in which intervention is crucial. An alternative therapy for stroke could be cellular growth factors, which participate in several pathways that mediate neuronal cell death.
