A cohort study of isolated brainstem infarction based on head MR imaging and clinical findings.

Objective: The prognosis of patients with isolated brainstem infarction (BSI) differs on an individual patient basis. This study was undertaken to analyze the influences of different imaging and clinical features with the prognosis of patients with BSI.

Methods: The study population was derived from a multicenter study of intracranial atherosclerosis in China.

DPP-4 inhibitors promote proliferation and migration of rat brain microvascular endothelial cells under hypoxic/high-glucose conditions, potentially through the SIRT1/HIF-1/VEGF pathway.

Background: Vascular disease in diabetes, for example, stroke, presents a significant public health burden. Recently, the dipeptidyl peptidase 4 (DPP-4) inhibitor linagliptin has been found to counteract stroke among diabetic patients, showing great promise in drug repurposing and indication expansion. However, the molecular basis of this protection mechanism remains unknown.
