The impact of insulin resistance, gender, genes, glucocorticoids and ethnicity on body fat distribution
Item type: Journal Article • Journal: Journal of Endocrinology, Metabolism and Diabetes of South Africa • Authors: NJ Crowther --- Department of Chemical Pathology, National Health Laboratory Service, South Africa WF Ferris --- Department of Medicine, Faculty of Health Sciences, South AfricaThe metabolic consequences of obesity are highly dependent on body fat distribution and total body fat mass. Visceral adipose tissue in particular has been found to play an important aetiological role in obesity-related disorders. The contrasting fat distribution between genders,... -
Adrenal insufficiency in critically ill septic patients at Dr George Mukhari Hospital
Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia • Authors: MJ Mpe --- Department of Intensive Care, South Africa NC Muleba --- Department of Intensive Care, South Africa EM Selepe --- Department of Intensive Care, South Africa TG Mothabeng --- Department of Intensive Care, South AfricaRationale: Adrenal insufficiency occurs with varying frequency in critically ill patients. It is usually associated with a high mortality and poor clinical outcome. Objective: To determine the incidence of adrenal failure in patients with severe sepsis and septic shock admitted... -
The use of clove oil to induce anaesthesia, and its effects on blood chemistry, in Lates niloticus from Lake Victoria, Uganda
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: D Kahwa --- Department of Wildlife and Aquatic Resources, College of Veterinary Medicine, Animal Resources and Biosecurity, Uganda J Rutaisire --- Aquaculture Research and Development Centre, Uganda H Kaiser --- Department of Ichthyology and Fisheries Science, South AfricaThe efficacy of clove oil as an anaesthetic and its effects on blood parameters in Nile perch Lates niloticus were evaluated in 2010. Clove oil concentrations of 49.3, 73.9 and 98.5 mg l−1 induced anaesthesia in <3 min, while the average recovery... -
Cortisol stress response and histopathological alteration index in Clarias gariepinus exposed to sublethal concentrations of Qua Iboe crude oil and rig wash
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: JK Saliu --- Ecotoxicology Unit, Department of Zoology, Nigeria SA Oluberu --- Ecotoxicology Unit, Department of Zoology, Nigeria II Akpoke --- Ecotoxicology Unit, Department of Zoology, Nigeria UD Ukwa --- Ecotoxicology Unit, Department of Zoology, NigeriaThe histological effect on and stress response of post juvenile Clarias gariepinus exposed to Qua Iboe crude oil and rig wash were investigated. Fish weighing 60–90 g and measuring 16–18 cm were exposed for 7–28 days to 8.00 ml−1 Qua... -
Physiological response to angling of Africa’s premier freshwater angling species, the tigerfish Hydrocynus vittatus
Item type: Journal Article • Journal: African Zoology • Authors: Ruan Gerber --- Water Research Group, Unit for Environmental Sciences and Management, South Africa Glyn Howatson --- Water Research Group, Unit for Environmental Sciences and Management, South Africa Richard Greenfield --- Centre for Aquatic Research, Department of Zoology, South Africa Ina Wagenaar --- Centre for Aquatic Research, Department of Zoology, South Africa Nico Smit --- Water Research Group, Unit for Environmental Sciences and Management, South AfricaAngling fraternities widely promote catch-and-release (C&R) as a fisheries management tool. This study aimed to determine the physiological response of Africa’s premier freshwater angling species, the tigerfish Hydrocynus vittatus, to C&R angling in the Okavango Delta, Botswana. Standard angling techniques... -
Non-invasive assessment of adrenocortical activity as a measure of stress in leopards Panthera pardus
Item type: Journal Article • Journal: African Zoology • Authors: Andrea B Webster --- Endocrine Research Laboratory, Department of Anatomy and Physiology, South Africa Richard EJ Burroughs --- Department of Production Animal Studies. Faculty of Veterinary Science, South Africa Peter Laver --- Endocrine Research Laboratory, Department of Anatomy and Physiology, South Africa André Ganswindt --- Endocrine Research Laboratory, Department of Anatomy and Physiology, South AfricaLeopards Panthera pardus are classified in the IUCN Red List as Vulnerable, primarily due to habitat loss, natural prey base depletion and exploitation caused by various anthropogenic activities. Although protected areas are important for leopard conservation, the majority of suitable... -
Physiological stress response and recovery of an important estuarine fishery species, dusky kob Argyrosomus japonicus, after a simulated catch-and-release event
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: NK Arkert --- , South Africa A-R Childs --- , South Africa MI Duncan --- , South Africa M Farthing --- , South Africa WM Potts --- , South AfricaCatch and release (C&R) angling is a popular pastime the world over; however, studies have found that fish can experience considerable stress during a C&R event. To determine the effect of a C&R event on angled fishes, the physiological stress... -
The utility of serial prolactin sampling in healthy adult volunteers
Item type: Journal Article • Journal: Journal of Endocrinology, Metabolism and Diabetes of South Africa • Authors: Reinhardt Dreyer --- , South Africa Amanda Beukes --- , South Africa Mariza Hoffmann --- , South Africa Wessel Meyer --- , South Africa Ankia Coetzee --- , South AfricaBackground: Stress hyperprolactinemia is a common cause of elevated prolactin (PRL) and often leads to additional investigation and radiation exposure. The results of PRL serial sampling in healthy adult volunteers to determine the utility of delayed collection are reported.
