There is a lack of representative samples to provide reliable and accurate seroprevalence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) as well as behavioural information among men who have sex with men (MSM) in Singapore. We used respondent driven sampling (RDS) to recruit MSM. Participants completed a survey used by Asian Internet MSM Sex Survey (AIMSS) and ...

This paper explores bias in the estimation of sampling variance in Respondent Driven Sampling (RDS). Prior methodological work on RDS has focused on its problematic assumptions and the biases and inefficiencies of its estimators of the population mean. Nonetheless, researchers have given only slight attention to the topic of estimating sampling variance in RDS, despite the importance of varianc...

In the context of the Community Programme in the field of Health, the European Commission financed a series of initiatives to support the development and use of indicators for planning health services for Rare Diseases (RDs). The European Project for Rare Disease National Plans Development (EUROPLAN) elaborated a set of 59 process and outcome indicators, for monitoring the implementation and fo...

Radial distribution systems (RDS) require special load flow methods to solve power flow equations owing to their high R/X ratio. Increasing use of power electronic devices and effect of magnetic saturation cause harmonics in RDS. This paper proposes a novel algorithm to compute the power flow solution of a RDS accounting for all the harmonic components. It uses a recursive solution technique. T...

The incidence of respiratory distress syndrome (RDS) among singleton infants of Cardiff residents was greater during 1970-4 than in the preceding five years. This was consistent with changes in the distribution of gestational age and birth weight. Case fatality rates among infants with RDS fell only slightly during the period examined. Detailed examination of secular trends during 1965-75 sugge...

Respiratory distress syndrome (RDS) is the leading cause of neonatal respiratory distress in our country and is the commonest disorder requiring assisted ventilation all over the world(l,2), Exogenous surfactant administration is now an established mode of therapy in neonatal RDS (hyaline membrane disease, HMD). Ever since the first report of successful surfactant replacement therapy in neonate...

Introduction: The aim of study was to compare umbilical cord blood selenium levels in respiratory distress syndrome (RDS) and non RDS preterm babies.    Methods: Umbilical cord blood selenium levels of all preterm newborn born during a 6-month period were enrolled in the study. They were divided into two groups: RDS and non RDS. Selenium level was assessed by using electro-thermal atomic ab...

Retinal degeneration slow (RDS/PRPH2) is critical for the formation of the disc/lamella rim in photoreceptor outer segments (OSs), but plays a different role in rods vs. cones. Without RDS, rods fail to form OSs, however, cones lacking RDS (in the rds(-/-)/Nrl(-/-)) exhibit balloon-like OSs devoid of lamellae. We show that distribution of most proteins in the lamella and PM domains is preserved...

Fetal lung maturity assessment in twin pregnancy has been discussed, but is still controversial. The purpose of this study is to predict the occurrence of respiratory distress syndrome (RDS) using lamellar body count (LBC) and analyze the validity of LBC for fetal lung maturity assessment in twin pregnancy. Three-hundred two amniotic fluid samples were obtained at cesarean section from 29 to 38...

The inherited retinal dystrophies represent a large and heterogenous group of hereditary neurodegenerations, for many of which, the molecular defect has been defined. However, the mechanism of cell death has not been determined for any form of retinal degeneration. The retinal degeneration slow (rds-/-) mutation of mice is associated with nondevelopment of photoreceptor outer segments and gradu...
