Primary dysmenorrhea is characterized by painful uterine cramps, near and during menstruation, that have an impact on personal life and productivity. The effect on sleep of this recurring pain has not been established. We compared sleep, nocturnal body temperatures, and hormone profiles during the menstrual cycle of 10 young women who suffered from primary(More)
Body temperature and sleep change in association with increased progesterone in the luteal phase of the menstrual cycle in young women. The mechanism by which progesterone raises body temperature is not known but may involve prostaglandins, inducing a thermoregulatory adjustment similar to that of fever. Prostaglandins also are involved in sleep regulation(More)
BACKGROUND The 4-variable Modification of Diet in Renal Disease (4-v MDRD) and Cockcroft-Gault (CG) equations are commonly used for estimating glomerular filtration rate (GFR); however, neither of these equations has been validated in an indigenous African population. The aim of this study was to evaluate the performance of the 4-v MDRD and CG equations for(More)
Point-of-care (POC) blood testing is intended to provide results more rapidly than can be obtained from a central laboratory. Precision and accuracy of the CardioChek PA and Cholestech LDX analysers were compared to clinical diagnostic laboratory methods. In 100 patients, total cholesterol (TC), triglycerides (TG), HDL cholesterol (HDL-C) and LDL(More)
Adhesion of leukocytes to endothelial cells via cell adhesion molecules (CAMS) is thought to be pivotal in the initiation of atherosclerosis. As patients with familial hypercholesterolaemia (FH) are known to develop severe, premature coronary artery disease (CAD), we investigated the usefulness of soluble forms of CAMS namely vascular cellular adhesion(More)
Alkaline phosphatase (ALP) is expressed in 3T3-L1 preadipocytes, and its activity increases during adipogenesis. The purpose of this study was to determine whether ALP activity could be used as a measure of intracellular lipid accumulation in human preadipocytes and 3T3-L1 cells and which of the factors that induce adipogenesis are responsible for(More)
OBJECTIVE As alkaline phosphatase may play a role in cell differentiation, our aim was to study the possible role of this enzyme in the differentiation of preadipocytes (3T3-L1 cells) into adipocytes. RESEARCH METHODS AND PROCEDURES 3T3-L1 cells were grown in medium containing insulin, dexamethasone and IBMX to induce adipogenesis. Adipogenesis was(More)
BACKGROUND A previous study has demonstrated that alkaline phosphatase (AP) may play a role in the control of intracellular lipid accumulation in the rodent preadipocyte cell line, 3T3-L1. The present study investigated whether AP may have a similar function in preadipocytes isolated from human mammary gland tissue. METHODS Preadipocyte maturation was(More)
AIM To determine whether high-quality nurse-recorded auscultatory blood pressure (BP) values obtained at a single visit predict cardiovascular target organ changes as closely as ambulatory BP measurements. METHODS In a randomly selected population sample (n = 458, 21% receiving antihypertensive treatment; approximately 40% hypertensive), we compared(More)
In high-Na(+), low-K(+) diets, which suppress renin release in salt-sensitive groups, the mechanisms maintaining increases in renin-angiotensin-aldosterone system activation downstream from renin and renin-angiotensin-aldosterone system-induced effects on blood pressure (BP) are uncertain. Whether circulating angiotensinogen concentrations (AGT) or its(More)
