The effect of lower body weight support on arterial wave reflection in healthy adults.

Body weight support (WS) during treadmill exercise is used to rehabilitate orthopedic/neurological patients. WS lowers musculoskeletal strain and load. It compresses the lower body and increases intrathoracic volume.

Psoas abscess secondary to Pott's disease--an unusual presentation in a young child.

Psoas abscess in neonates and infants are rare. Primary psoas abscesses are said to be more common in young children. Limping, fever and abdominal pain has been described to be the way psoas abscesses usually present.

Cardiovascular health knowledge and behavior in patient attendants at four tertiary care hospitals in Pakistan--a cause for concern.

Background: Knowledge about coronary heart disease (CHD) and its risk factors is an important pre-requisite for an individual to implement behavioral changes leading towards CHD prevention. There is scant data on the status of knowledge about CHD in the general population of Pakistan. The objective of this study was to assess knowledge of CHD in a broad Pakistani population and identify the factors associated with knowledge.

G-protein beta-3 subunit gene 825C>T dimorphism is associated with left ventricular hypertrophy but not essential hypertension.

Background: The human G-protein beta 3 subunit gene (GNB3) and some of its variants are known to be important genetic influences involved in essential hypertension (EH). Left ventricular hypertrophy (LVH) has long been thought to be an end point of EH, rather than a separate entity, though it is influenced by a unique set of hormonal, vascular and genetic factors.

Methods/materials: We carried out a retrospective, case-control study of a GNB3 825 C>T dimorphism among nationals from the United Arab Emirates (Emirati), an ethnic group characterized by no alcohol intake and no cigarette smoking, for putative correlations with EH and LVH.
