Studies on the Effects of Hypercholesterolemia on Mouse Ophthalmic Artery Reactivity.

Atherogenic lipoproteins may impair vascular reactivity, leading to tissue damage in various organs, including the eye. This study aimed to investigate whether ophthalmic artery reactivity is affected in mice lacking the apolipoprotein E gene (ApoE-/-), a model for hypercholesterolemia and atherosclerosis. Twelve-month-old male ApoE-/- mice and age-matched wild-type controls were used to assess vascular reactivity using videomicroscopy.

Effects of Resveratrol on Vascular Function in Retinal Ischemia-Reperfusion Injury.

Ischemia-reperfusion (I/R) events are involved in the development of various ocular pathologies, e.g., retinal artery or vein occlusion.

Sulodexide Prevents Hyperglycemia-Induced Endothelial Dysfunction and Oxidative Stress in Porcine Retinal Arterioles.

Diabetes mellitus may cause severe damage to retinal blood vessels. The central aim of this study was to test the hypothesis that sulodexide, a mixture of glycosaminoglycans, has a protective effect against hyperglycemia-induced endothelial dysfunction in the retina. Functional studies were performed in isolated porcine retinal arterioles.

Sleeve gastrectomy morphology and long-term weight-loss and gastroesophageal reflux disease outcomes.

Background: The relationship between sleeve gastrectomy (SG) morphology and long-term weight-loss and gastroesophageal reflux disease (GERD) outcomes is unknown.

Methods: All patients (n = 268) undergoing SG performed by 3 surgeons at a single academic institution from January 1, 2010 to December 31, 2012 were included. Long-term weight-loss and GERD outcomes were available for 90 patients which were incorporated in analyses.

Independent association of preoperative Hill grade with gastroesophageal reflux disease 2 years after sleeve gastrectomy.

Background: The sleeve gastrectomy (SG) is associated with postoperative gastroesophageal reflux disease (GERD). Higher endoscopic Hill grade has been linked to GERD in patients without metabolic surgery. How preoperative Hill grade relates to GERD after SG is unknown.
