OBJECTIVE To evaluate the yield of a routine voluntary HIV testing program compared with traditional provider-referred voluntary counseling and testing (VCT) in a hospital-affiliated outpatient department (OPD) in Durban, South Africa. DESIGN AND METHODS In a prospective 14-week "standard of care" period, we compared OPD physician logs documenting patient referrals to the hospital VCT site wi...

BACKGROUND To determine if expenditures for dentistry (DENT) correlate with severity of chronic kidney disease (CKD). METHODS A total of 10,457 subjects were enrolled from January 2008 to December 2010, divided into three groups: healthy control (HC) group (n = 1,438), high risk (HR) group (n = 3,392), and CKD group (n = 5,627). Five stages were further categorized for the CKD group. OPD util...

BACKGROUND Organophosphorus hydrolase (OPH) is a type of organophosphate-degrading enzyme which is widely used in the bioremediation process. OBJECTIVES In this study, the periplasmic and cytoplasmic productions and the activity of recombinant OPH in Escherichia coli were investigated and compared using two pET systems (pET21a and pET26b). MATERIALS AND METHODS The sequence encoding the opd...

INTRODUCTION The prevalence of oropharyngeal dysphagia (OPD) in children with cerebral palsy (CP) is estimated to be between 19% and 99%. OPD can impact on children's growth, nutrition and overall health. Despite the growing recognition of the extent and significance of health issues relating to OPD in children with CP, lack of knowledge of its profile in this subpopulation remains. This study ...

Background: Prevalence of undernutrition in developing countries, though on the declining trend, is still a cause for alarm.The prevalence in India is among the highest in the world. In such a scenario,this study was undertaken to find out the nutritional status of under five children attending the pediatric OPD of a tertiary care hospital of North East india. Methodology: The study was an OPD ...

Particle filters are widely used in mobile robot localization and mapping. It is well-known that choosing an appropriate proposal distribution plays a crucial role in the success of particle filters. The proposal distribution conditioned on the most recent observation, known as the optimal proposal distribution (OPD), increases the number of effective particles and limits the degeneracy of filt...

Large stellar telescope is indispensable for astronomy. Aperture synthesis is a well-known technique to simulate a large space telescope by an array of small telescopes. Condition for aperture synthesis is that the light of the telescopes have to be combined coherently. Therefore, an interferometric Fringe Sensor (FS) to detect and stabilize the Optical Path Difference (OPD) between light from ...

UNLABELLED Vascular endothelial growth factor (VEGF) is a protein that increases vascular permeability and induces the proliferation, migration and survival of endothelial cells. Bisphosphonates (BPs) are antiresorptive drugs that are widely used in the treatment of bone metabolism diseases and bone metastases. Since 2003, cases of bisphosphonate-related osteonecrosis of the jaw (BRONJ) have be...

We developed a new method to identify the separate cellular compartments in the optical path delay (OPD) maps of un-labeled spermatozoa. This was conducted by comparing OPD maps of fixed, un-labeled spermatozoa to bright field images of the same cells following labeling. The labeling enabled us to identify the acrosomal and nuclear compartments in the corresponding OPD maps of the cells. We the...

Online professional development (OPD) for teachers is an increasingly popular and viable alternative to face-to-face professional development. While OPD can be effective, little is known about OPD’s design and implementation features that maximize its impact. Using data from a large-scale OPD initiative, this correlational study (N = 1231) investigates antecedents of selfreported changes in te...
