Hypertension affects one billion people and is a principal reversible risk factor for cardiovascular disease. Pseudohypoaldosteronism type II (PHAII), a rare Mendelian syndrome featuring hypertension, hyperkalaemia and metabolic acidosis, has revealed previously unrecognized physiology orchestrating the balance between renal salt reabsorption and K(+) and(More)
C57BL/10 female mice were primed to the male specific antigen H-Y, either by grafting with syngeneic male tail skin or by i.p. injection of syngeneic male spleen cells. Primed female spleen cells, either unseparated or filtered through nylon wool to remove most of the B lymphocytes, were then cultured for 5 days in vitro with irradiated syngeneic male(More)
Once considered rare, primary aldosteronism (PAL) is now regarded as the commonest potentially curable and specifically treatable form of hypertension. At Greenslopes Hospital Hypertension Unit (GHHU), the decision in 1991 to screen all (and not just hypokalemic or resistant) hypertensives by aldosterone/renin ratio (ARR) testing led to a 10-fold increase(More)
Physiological and mood state parameters were monitored during a 6-month swimming season in an attempt to determine markers of overtraining and recovery. Fourteen elite male and female swimmers were tested early-, mid-, and late-season and shortly before and after major competition. Training details and subjective ratings of well-being were compiled by the(More)
This study investigated the role of the complement activation fragment C5a in secondary pathology following contusive spinal cord injury (SCI). C5ar(-/-) mice, which lack the signaling receptor for C5a, displayed signs of improved locomotor recovery and reduced inflammation during the first week of SCI compared with wild-type mice. Intriguingly, the early(More)
Familial hyperaldosteronism type II (FH-II) is characterized by autosomal dominant inheritance and hypersecretion of aldosterone due to adrenocortical hyperplasia or an aldosterone-producing adenoma; unlike FH type I (FH-I), hyperaldosteronism in FH-II is not suppressible by dexamethasone. Of a total of 17 FH-II families with 44 affected members, we studied(More)
Plasma renin concentrations are extremely low, requiring high sensitivity methods to detect low renin hypertensive states. Moreover, plasma prorenin must not cryoactivate to renin to avoid falsely high values. The enzyme kinetic plasma renin activity (PRA) test has the required sensitivity, whereas direct renin assays and PRA tests with short incubation(More)
Huntington's disease (HD) is an incurable neurodegenerative condition characterized by progressive motor and cognitive dysfunction, and depletion of neurons in the striatum. Recently, BACHD transgenic mice expressing the full-length human huntingtin gene have been generated, which recapitulate some of the motor and cognitive deficits seen in HD. In this(More)
AIMS Hyponatraemia is one of the major adverse effects of thiazide and thiazide-like diuretics and the leading cause of drug-induced hyponatraemia requiring hospital admission. We sought to review and analyze all published cases of this important condition. METHODS Ovid Medline, Embase, Web of Science and PubMed electronic databases were searched to(More)
