pulmonary hypertension syndrome (ascites) is a metabolic disorder in fast-growing broilers. inconsistency of oxygen requirement and the cardiovascular ability make the birds susceptible to ascites. incidence of ascites was accompanied by right ventricular hypertrophy, fluid accumulation in the abdominal cavity and finally mortality. the objective of the current study was to review the genetic b...

INTRODUCTION This study aimed to describe the morphology of age-related macular degeneration (AMD) as well as to obtain an estimate of the population-based incidence rate in Singapore. METHODS This is a retrospective hospital-based study of AMD cases seen in 1991 and 1992 at the Singapore National Eye Centre (SNEC), a tertiary eye centre. All case notes recorded with the International Classif...

PURPOSE Exudative age-related macular degeneration (exudative AMD) is a common vision-threatening disease, with both environmental and genetic factors contributing to its development. Recently, homozygosity for the 72Met variant of the pigment epithelium-derived factor (PEDF) Met72Thr gene polymorphism (rs1136287) was identified as a novel risk factor for exudative AMD in Chinese patients from ...

BACKGROUND The exact pathogenetic mechanisms of Coats' disease remain unknown. In this report, we show two cases of Coats' disease that achieved a favorable prognosis with the combined treatment of intravitreal bevacizumab (IVB) injection prior to photocoagulation, although both initially resisted photocoagulation therapy. CASE PRESENTATIONS Case 1 was a 15-year-old boy with initial visual ac...

BACKGROUND Effective therapeutic options are limited for the management of chronic central serous chorioretinopathy (CSCR) complicated by exudative retinal detachments (RD). The authors describe the resolution of one such case following partial thickness scleral resection with mitomycin C. CASE PRESENTATION This 39-year-old male presented with a unilateral inferior exudative RD in the right e...

The eyes of 47 subjects with exudative age-related macular degeneration in the fellow eye were tested with a battery of visual function tests at baseline and followed for at least 18 mo. Fundus photographs also were obtained at baseline. These photographs were used to verify the absence of exudative lesions in the 47 eyes tested. Functional and funduscopic baseline data each were compared again...

BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...

purpose: to determine the correlation between body mass index (bmi) and exudative age-related macular degeneration (armd). methods: this case-control study was conducted on 60 patients with exudative armd and 60 controls, both aged over 50. age, sex, cigarette smoking and blood pressure were evaluated beside bmi. data analysis was performed by spss software, version 9.0 using pearson chi square...

Six hundred 1-d old male broilers (Ross 308) were assigned into four experimental groups; each was composed of 5replications of 30 birds including control (0), 10, 20 and 40 mg/kg nano-ZnO in the basal diets. Birds were exposed to low ambient temperature (15 to 18 ˚C) to induce ascites. Blood parameters including; activity of aspartate transferase (AST), alanine transferase (ALT), lactate dehyd...

The increasing susceptibility of broiler chickens to ascites syndrome has coincided with a continuing genetic and nutritional improvement in their feed efficiency and growth rate. Ascites is multifactorial and interactions between environmental and endogenous factors play a particularly important role. The selection of fast growing broilers for high feed efficiency, which is characterized by hy...
