purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...

Differential stretch of a retinal surface with an initially uniform cell density has been repeatedly implicated as one of the developmental mechanisms that produces the topographic organization of cell density in the adult retina, notably the area centralis or visual streak versus peripheral regions. It is known that intraocular pressure is required to produce the normal conformation and thinni...

Background: Low Back Pain (LBP) is one of the most prevalent problems associated with sport activities. The present study aimed to investigate the relationship between pain and plantar pressure variables. In addition, we compared these variables in male and female athletes with LBP. Methods: In this study, 47 participants with the age range of 18 to 25 years w...

PURPOSE The bugeye mutant has an enlarged eye phenotype, presumably because of elevated intraocular pressure. Since elevated intraocular pressure is a significant risk factor for glaucoma, the bugeye zebrafish mutant may be a model organism for the disease. METHODS The optomotor response (OMR) was used to assess visual responsiveness in both larval and adult zebrafish. Electroretinograms (ERG...

The objectives of this study were to Investigate the changes in blood pressure ( systolic and diastolic) , serum lipids , glucose, electrolytes, blood cell count and weight during Ramadan fasting in apparently healthy muslem men. Eighty male college students or staffs were followed in 3 stages during the month of Ramadan. Blood pressure, weight and height were measured on day one ( baseline) ,a...

  Abstract   Meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal   melanocytes. The locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. The manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that c...

background the transjugular intrahepatic portosystemic stent-shunt (tipss) builds a shortcut between the portal vein and a liver vein, and represents a sophisticated alternative to open surgery in the management of portal hypertension or its complications. objectives to describe clinical experiences with a low-profile nitinol stent system in tipss creation, and to assess primary and long-term s...
