The aim of the present study was to examine the selectivity of descending control of nociceptive information in the spinal dorsal horn following neuronal activation at "pressor" sites in the anterior hypothalamus. Extracellular single-unit activity was recorded from 11 dorsal horn neurons in the lower lumbar spinal cord of anesthetized rats. Neurons(More)
AIM To review post-anaesthetic hepatitis in a South African population, given that halothane use is restricted in other countries because of the high mortality and morbidity of its associated type II (idiosyncratic) hepatitis, even though it is still widely used in South Africa. STUDY DESIGN Descriptive, retrospective analysis. PATIENTS AND METHODS(More)
Magnesium (Mg) alloys are promising scaffolds for the next generation of cardiovascular stents because of their better biocompatibility and biodegradation compared to traditional metals. However, insufficient mechanical strength and high degradation rate are still the two main limitations for Mg materials. Hydrofluoric acid (HF) treatment and collagen(More)

BACKGROUND Skin biopsy reports of basal cell carcinoma and squamous cell carcinoma are often accompanied by comments on the margins. A physician's management can be influenced by such reports, particularly when the margins are reported as clear and no further interventions are pursued. OBJECTIVE To retrospectively review pathology margins on Mohs(More)
