This paper describes the development, content, and capabilities of the online Global HIV Archive (GHA). With the goal of facilitating widespread adaptation and appropriate use of efficacious HIV prevention programs throughout the globe, GHA has: first, expanded and updated the search for HIV prevention programs originating in low-resource countries; second, identified those meritorious HIV prev...
Acetophenone 2’, 4’dihydroxy semicarbazone [A24DHS], a new analytical reagent is proposed as a sensitive and selective spectrophotometric reagent for Vanadium (V). The reagent A24DHS is synthesized in the laboratory and characterized by NMR, IR and elemental analysis. A selective spectrophotometric method is presented for the trace determination of Vanadium using A24DHS as spectrophotometric re...
In 136 normal growing children between the ages of 1 and 18 yr, bone mineral content (BMC) at the level of the lumbar spine (L2-L4) was determined with a commercial dual-photon absorptiometer. BMC was calculated as BML (BMC per unit length) and BMD (BMC per unit surface). The mean lumbar spine BML of the studied children (2.53 +/- 0.86 gHA/cm) was significantly lower than the spinal mineral con...
PURPOSE To assess the incidence rate of endophthalmitis after 25-gauge pars plana vitrectomy and to compare it with the endophthalmitis rate after 20-gauge pars plana vitrectomy. DESIGN Retrospective, interventional, comparative cohort study. PARTICIPANTS Eight thousand six hundred one consecutive pars plana vitrectomy surgery patients. METHODS Surgeries performed at a single institution ...
This study investigates the effect of cooking, storage, and reheating conditions on the formation of cholesterol oxidation products (COPs) in pork loin. Samples of pork loin procured 24 h postmortem were initially processed and assessed for total fat and cholesterol content. The cooking methods evaluated were pan roasting, steaming, oven grilling, and microwaving. Cooked pork loin samples were ...
We present a comparison of three neural PCA techniques: the GHA by Sanger, the APEX by Kung and Diamataras, and the { APEX rst proposed by the present authors. Through numerical simulations and computational complexity evaluations we show the {APEX algorithms exhibit superior capability and interesting features.
G lobal Health Action (GHA) has published more than 550 articles since its launch in May 2008. GHA was truly the first Open Access global health journal. From 2008 till date, the journal has remained true to its aim to 'contribute to fuelling a more concrete, hands-on approach to global health challenges' (1). Published content fulfills the founders' expectation of addressing a global health ag...
Climate-related environmental and humanitarian crisis are important challenges in the Great Horn of Africa (GHA). In the absence of long-term past climate records in the region, tree-rings are valuable climate proxies, reflecting past climate variations and complementing climate records prior to the instrumental era. We established annually resolved multi-century tree-ring chronology from Junip...
In adult female monkeys, serum concentrations of insulin-like growth factor I (IGF-I) are decreased by estradiol replacement, whereas levels of IGF-binding protein-3 (IGFBP-3) are increased. Furthermore, chronic IGF-I supplementation elevates serum IGFBP-3 despite a suppression of GH. To better understand how estradiol and IGF-I affect the IGF-I axis, a series of three studies was conducted to ...
abstract i the purpose of this study was to launch a thorough investigation concerning the possibility of differing orientations to the writing proficiency construct by native and non-native english speaking teacher raters. it mainly revolved around the international english language testing system (ielts) that is widely administered and employed as a measure of general proficiency in englis...
