conclusion the incidence of rop is relatively high in this region. risk factors for rop among very premature infants include hypoxia, severe hyperoxia, relatively low blood spo2, gestational age, birth weight, and apgar score. results the incidence of rop was 26.2%. significant differences between the rop and control groups were observed, these include; gestational age, sex, birth weight, apgar...

purpose : to evaluate the efficacy of autologous plasmin in pediatric vitrectomy and to report the anatomic outcomes of autologous plasmin assisted pediatric vitrectomy methods : in an interventional prospective study, thirty-four pediatric patients with vitreoretinal disorders who needed vitrectomy during 2008 to 2010, included in the study. the patients were divided into two groups: the retin...

PURPOSE Recent studies have reported that loss of bone mass is associated with renal function decline and increased fracture risks in chronic kidney disease (CKD) patients. The aim of this study was to investigate the best estimated glomerular filtration rate (eGFR) equation to detect osteopenia in CKD patients. MATERIALS AND METHODS This was a cross-sectional study, and 780 patients aged 50 ...

it has been estimated that each year 50,000 newborns born prematurely and underweight and are candidates to have retinopathy of prematurity (rop) .1 in the developing countries where we see most of the blind children, rop is accused to be one of the essential causes of blindness.2 rop and its consequences (impaired vision and blindness) could be prevented in most cases by an early ocular examin...

osteoporosis is a metabolic disease characterized by reduction in bone density and susceptibility to deformity and fracture. some studies show that osteoblasts can create inter-cellular free radicals that lead to cellular death. superoxide dismutase (sod) plays an essential role in cell defense against reactive oxygen metabolites. the purpose of this study was to measure the plasma sod activiti...

BACKGROUND Globally, prematurity is the leading cause of death in children under the age of 5. Many efforts have focused on clinical approaches to improve the survival of premature babies. There is a need, however, to explore psychosocial, sociocultural, economic, and other factors as potential mechanisms to reduce the burden of prematurity. Women's empowerment may be a catalyst for moving the ...

This document is an overview of formal models for AOP. It covers most existing formalisms. Instead of explaining the technical details of each work, we identify key concepts for AOP, and mention how they are modeled.
