Intensive short course chemotherapy in the management of tuberculous meningitis
SETTING: Short course chemotherapy for tuberculous meningitis (TBM) is advocated by several groups, but relatively few children have been so treated and followed up. METHODS: A prospective, observational study of isoniazid ...
Isoenzymes of adenosine deaminase in pleural effusions: A diagnostic tool?
SETTING: Tygerberg Hospital, an academic teaching hospital, Republic of South Africa. OBJECTIVE: To identify the adenosine deaminase (ADA) isoenzymes as a diagnostic tool for tuberculosis in pleural effusions with increased ...
Sequence variation and subtyping of human and simian T-cell lymphotropic virus type I strains from South Africa
We report on the subtyping of South African primate T-cell lymphotropic virus type I (PTLV-I) strains by investigating the LTR region using sequence analysis and restriction fragment length polymorphism (RFLP) techniques. ...
Dynamics of respiratory gas exchange during exercise after correction of congenital heart disease
In pediatric exercise testing, conventional measures of aerobic exercise function such as maximal O2 uptake or the ventilatory anaerobic threshold (VAT) use only one value for the assessment of exercise capacity. We studied ...
G-protein regulation of the solubilized human zona pellucida-mediated acrosome reaction and zona pellucida binding
Purpose: The study aimed to evaluate the (i) regulatory role of G(i)- like protein during the acrosome reaction (AR) of normal sperm donors and (ii) the role of intact acrosomes during sperm-zone binding. Methods: The ...
Use of failed-fertilized oocytes for diagnostic zona binding purposes after sperm binding improvement with a modified medium
Purpose: Because the availability of prophase oocytes for zona binding testing is limited, we compared sperm binding to the zona of failed- fertilized intracytoplasmic sperm injection (ICSI) and in vitro fertilization (IVF) ...
Defining bioassay conditions to evaluate sperm/zona interaction: Inhibition of zona binding mediated by solubilized human zona pellucida
Objective: Our goal was to study the influence of solubilized human zonae pellucidae on zona binding potential and acrosome reaction. Materials and Methods: Zona pellucida (ZP) solutions were prepared by dissolving zona ...
Fertilization and pregnancy using metaphase I oocytes in an intracytoplasmic sperm injection program
Purpose: In this study we investigated whether metaphase I oocytes collected in an intracytoplasmic sperm injection program could successfully be matured and fertilized by injecting aged (>20-hr) spermatozoa. Materials and ...

Smoking and alcohol use during pregnancy affects preterm infants' docosahexaenoic acid (DHA) status
This study investigated the effect of alcohol consumption and smoking during pregnancy on the fatty acid composition of the infants. A total of 40 very-low-birth-weight (VLBW) infants, weighing between 750 and 1500g, were ...
