Intravitreous Anti-VEGF vs. Vitrectomy for Vitreous Hemorrhage in PDR
Vitreous hemorrhage in proliferative diabetic retinopathy (PDR) is a common cause of vision loss in diabetic patients. This clinical research protocol compares the efficacy and safety of intravitreous anti-VEGF injections with vitrectomy for treating vitreous hemorrhage. It aims to evaluate visual acuity outcomes over time and characterize the follow-up course for each treatment regimen. The study involves a multi-center randomized clinical trial with a primary outcome of Visual Acuity Area Under the Curve over 6 months for eyes meeting specific criteria.

Fatty Liver and Kidney Syndrome (FLKS) Fatty Liver and Kidney Syndrome (FLKS)
Fatty Liver and Kidney Syndrome (FLKS) in young flocks : Is a manifestation of a failed metabolic process allowing accumulation of fat in the liver and kidneys. Fatty liver in adult poultry flocks is commonly caused by the inadequate addition of biotin and/or choline chloride in the feed.
Morbidity: affected chickens and is followed quickly by death. Mortality : Morbidity: Occurs rapidly in Mortality : May vary from May vary from 5 5- -35 35% . % .
