782 It is estimated that half or more of sexually transmitted infection (STI) care episodes in the South African formal health sector are treated by private general practitioners (GPs). Poorquality STI care has been well documented in this setting and has been the subject of some debate and policy responses. In the Department of Health’s HIV/AIDS and STD Strategic Plan for 2000 2005, the first ...

October 2005, Vol. 95, No. 10 SAMJ Great strides were made during the last century in the management of diabetes in pregnancy. Before the discovery of insulin in 1921 the outlook for the diabetic mother and her fetus was abysmal. With the advent of insulin, an emphasis on a team approach to care, improved methods of fetal surveillance, and a focus on metabolic normalisation brought about by int...

The gene, pixJ1 (formerly pisJ1), is predicted to encode a phytochrome-like photoreceptor that is essential for positive phototaxis in the unicellular cyanobacterium Synechocystis sp. PCC 6803 [Yoshihara et al. (2000) Plant Cell Physiol. 41: 1299]. The PixJ1 protein was overexpressed as a fusion with a poly-histidine tag (His-PixJ1) and isolated from Synechocystis cells. A zinc-fluorescence ass...

The enzymes of naphthalene metabolism are induced in Pseudomonas putida ATCC 17484, PpG7, NCIB 9816, and PG and in Pseudomonas sp. ATCC 17483 during growth on naphthalene or salicylate; 2-aminobenzoate is a gratuitous inducer of these enzymes. The meta-pathway enzymes of catechol metabolism are induced in ATCC 17483 and PPG7 during growth on naphthalene or salicylate or during growth in the pre...

The complex polar lipids of the hot spring cyanobacterial mat in the 50 to 55 degrees C region of Octopus Spring, Yellowstone National Park, and of thermophilic bacteria cultivated from this or similar habitats, were compared in an attempt to understand the microbial sources of the major lipid biomarkers in this community. Intact complex lipids were analyzed directly by fast atom bombardment ma...

Brown-rot decay results in rapid reduction in degree of polymerization of holocellulose, with concomitant strength loss without removing lignin. Development of new methods of wood protection will require focusing on early events in the sequence of fungal attack during colonization. Pit membranes (sapwood) of wood cell walls represent a readily available source of nonlignified carbohydrate, i.e....

Great strides were made during the last century in the management of diabetes in pregnancy. Before the discovery of insulin in 1921 the outlook for the diabetic mother and her fetus was abysmal. With the advent of insulin, an emphasis on a team approach to care, improved methods of fetal surveillance, and a focus on metabolic normalisation brought about by intensive insulin regimens and home gl...

November 2005, Vol. 95, No. 11 SAMJ Uncertainty as to the cause or causes of sudden and unexpected infant death and difficulty in excluding the possibility of infanticide, even after the performance of a ‘complete’ autopsy, was graphically illustrated in the London courts recently. A mother wrongly convicted of killing her two sons had her conviction quashed, and the eminent paediatrician who h...
