Innovative technologies and concepts will emerge as we move towards a more dynamic, service-based, market-driven infrastructure, where energy efficiency and savings can be facilitated by i nteractive distribution networks. A new g eneration of fully interactive Information and Communication Technologies (ICT) infrastructure has to be developed to support(More)
The preservation or reconstitution of a normal external auditory canal with the obliteration of or maintenance of an aerated maistoid cavity is possible by reconstruction of the lateral attic wall and posterior canal wall. Conserved homograft cartilage and autograft cartilage or bone are considered suitable. Connective tissue and lyophilised dura are not(More)
Heme oxygenase (HO)-1 is a stress response protein that is regulated by oxidative stress. HO-1 catalyzes the generation of biliverdin, carbon monoxide, and iron from heme. Lipopolysaccharide (LPS) and interleukin (IL)-1beta induce HO-1 through the binding of nuclear proteins to AP-1 motifs in enhancer regions upstream from the transcription start site. The(More)
Major depression is underdiagnosed by general practitioners, but the reasons for this are not clear. This study aimed to establish the prevalence of major depression and coexisting generalised anxiety disorder in a rural general practice in the Orange Free State. It also assessed the predictive value of a screening questionnaire for use by general(More)
A mixed oligonucleotide probe containing sequences encoding a septapeptide found in yeast, Drosophila and human DNA topoisomerase II was used to screen a genomic library of Trypanosoma brucei. A positive was obtained, and nucleotide sequencing shows that the entire gene encoding DNA topoisomerase II of this organism, TbrTOP2, resides within the T. brucei(More)
We observed the course of diabetes in 23 genetically diabetic mice (C 57 BL/KSJ mdb) and in 25 controls (C 57 BL/KSJ). Diabetes was not treated. Histological changes of pancreas, aorta, kidneys, and inner ear vessels were noted. Auditory function was tested by means of the pinnal reflex of Preyer for a frequency range between 4000 and 20000 cps. The(More)
An examination of 1300 students between the ages of 10 and 20 who had not yet been exposed to industrial noise was performed in order to establish to what extent general environmental noise influences hearing. The fact that there was no age-dependent increase of high tone hearing loss, as well as the small correlation between hearing loss and total noise(More)
Testicular temperature highly correlates with scrotal temperature. It has been postulated that cycling is associated with increased scrotal temperatures with time and consecutively with impaired semen quality. The aim of this study was to evaluate the influence of moderate cycling on scrotal temperature during highly standardized conditions in an(More)
