Immunological Determinants of Liver Transplant Outcomes Uncovered by the Rat Model.

abstract：BACKGROUND:Arterial hypertension (HT) is common in renal transplant recipients (RTRs). Control of HT is not optimal in this high-risk population despite recommendations for target blood pressure levels under 130/80 mm Hg. METHODS:We performed a cross-sectional analysis of the prevalence of uncontrolled HT, and using a...
