Evaluating the BED capture enzyme immunoassay to estimate HIV incidence among adults in three countries in sub-Saharan Africa
Serological assays for estimating HIV-1 incidence are prone to misclassification, limiting the accuracy of the incidence estimate. Adjustment factors have been developed and recommended for estimating assay-based HIV-1 ...
Microscopic studies on the Aspergillus flavus infected kernels of commercial peanuts in Georgia
This article describes the use of microscopy to prove the presence of the aflatoxin producing pathogen, Aspergillus flavus Link ex Fries in commercially available edible peanuts in Georgia. Light microscopy in combination ...
Selective lysis of erythrocytes infected with the trophozoite stage of Plasmodium falciparum by polyene macrolide antibiotics
The continuous increase in strains of the human malaria parasite Plasmodium falciparum resistant to most front-line antimalarial compounds is reason for grave clinical concern. The search for new drugs led us to investigate ...

Lack of interaction between α2-adrenoceptors and dopamine D2-receptors in mediating their inhibitory effects on [3H]dopamine release from rat nucleus accumbens slices
The α2-adrenoceptor agonist, UK14304, dose-dependently inhibited the electrically stimulated release of dopamine (DA) from rat nucleus accumbens slices. This effect was antagonized by idazoxan, confirming that it was an ...
Effects of α2- and β-adrenoceptor agonists on growth hormone secretion following lesion of the noradrenergic system of the rat
The aim of the present investigation was to lesion the noradrenergic system and to measure the effect on growth hormone (GH) secretion following peripheral administration of α2- and β-adrenoceptor agonists. Direct injection ...
Tioconazole in the treatment of vaginal candidosis
A 3-day treatment with tioconazole vaginal tablets (Gyno-Trosid; Pfizer) was used in 30 patients with vaginal candidosis during a prospective, mycologically controlled study. Candida yeasts were identified by microscopy ...
The effect of prebiotics on production of antimicrobial compounds, resistance to growth at low pH and in the presence of bile, and adhesion of probiotic cells to intestinal mucus
Aims: Screening of five bile salt-resistant and low pH-tolerant lactic acid bacteria for inhibitory activity against lactic acid bacteria and bacterial strains isolated from the faeces of children with HIV/AIDS. Determining ...
Screening for the production of extracellular hydrolytic enzymes by non-Saccharomyces wine yeasts
Aims: The objective of this study was to investigate what types of enzymes are being produced by non-Saccharomyces yeasts isolated from grapes in South Africa vineyards and clarified grape juice. These enzyme profiles could ...
Optimization of a rapid method for studying the cellular location of β-glucosidase activity in wine yeasts
Aims: To improve a method for determining β-glucosidase activity and to apply it in yeasts isolated from wine ecosystems from 'La Mancha' region and to know its cellular location. Methods and Results: A total of 82 wine ...
