PURPOSE OF REVIEW The present review discusses current concepts of HIV-associated neurocognitive disorders (HAND) in the era of antiretroviral therapy (ART). As the HIV epidemic enters its fourth decade (the second decade of ART), research must address evolving factors in HAND pathogenesis. These include persistent systemic and central nervous system (CNS)(More)
Seroprevalence, clinical findings, and lesions of contagious caprine pleuropneumonia (CCPP) in Beetal goats were recorded during an outbreak. The overall seroprevalence of CCPP was 32.50%. Confirmation of Mycoplasma mycoides in serum was carried out using counter immunoelectrophoresis (CIE) technique. The highest CIE-positive cases were recorded in the(More)
This study describes the effect of dietary levels of aflatoxin B1 (AFB1) and age of the birds upon the residue level in liver and muscles of broiler chicks. In three different experiments broiler chicks of 7, 14 and 28 days of age were kept for 7 days on contaminated rations having 1600, 3200 and 6400 μg/kg AFB1. AFB1 residues were detected earlier in(More)
OBJECTIVE To determine the histological grading and muscle invasion in Transitional Cell Carcinomas of the Urinary Bladder; and to evaluate whether any correlation exists between tumour grade and muscle invasion. METHOD A Retrospective study of all consecutive cases of Transitional Cell Carcinomas of the Urinary Bladder diagnosed at Aga Khan University(More)
Ninety 1-day old broiler chicks of mixed gender (as hatched) procured from a local hatchery were randomly divided into five equal groups. All the treatments were given through crop tubing. Groups 1-4 received cypermethrin (CY) (600mgkg(-1)b. wt.) daily for 30 days. In addition to CY (group 1), groups 2-4 received Vit E (150mgkg(-1)b. wt.), Se(More)
Deoxynivalenol (DON) has been recently documented to deteriorate intestinal morphology in chickens at dietary doses that are regarded as safe for this species. The present trial was conducted to explore the significance of these morphological changes in relation to intestinal absorptive functionality and DON metabolism. Ross broilers at 7 d of age were fed(More)
A total of 125 (ready to eat) processed food samples (70 intended for infant and 55 for adult intake) belonging to 20 different food categories were analyzed for aflatoxins contamination using Reverse Phase High Performance Liquid Chromatography (RP-HPLC) with fluorescent detection. A solvent mixture of acetonitrile-water was used for the extraction(More)
Broiler chicks were kept on feeds amended by the addition of 240 mg monensin and 15 mg selenium with or without 200 mg vitamin E/kg. After 12 days, birds in different groups were orally administered three doses of 250 mg monensin and 5 mg selenium/kg body weight. In the second experiment, after four weeks of adaptation on amended feeds, similar groups were(More)
