Molecular link between membrane cholesterol and Na+/H+ exchange within human platelets.

Incubation of human platelets with cholesterol-poor, cholesterol-normal and cholesterol-rich liposomes revealed that: (i) acquisition or depletion of platelet membrane cholesterol was highly selective; (ii) variation in membrane cholesterol was highly selective. Variation in membrane cholesterol content (cholesterol-to-phospholipid molar ratio from 0.15-1.

Total hip arthroplasty after McMurray's osteotomy.

Total hip arthroplasty (THA) was done as a secondary procedure after McMurray's osteotomy in 15 cases, with a time lapse of 14-132 months between the two operations. Marked improvement in pain and function was achieved in 14 cases, although hip stiffness was greater than that in primary THA cases. It was noted that delay in THA enhanced the operative difficulties and decreased the overall improvement obtained.

Histomorphological criteria for prognosis in breast cancer.

One hundred cases of carcinoma breast were analysed with regard to histological features and clinical follow-up. Bad prognostic factors included tumour size larger than 5cms; absent or minimal intraduct component in the tumour and absent or minimal periductal elastosis. Conversely significant intraduct component in the tumour and periductal elastosis were associated with better survival.

Metal inhibition of calmodulin activity in monkey brain.

Studies were conducted to investigate the effect of vanadium (V5+), cadmium (Cd2+), mercury (Hg2+), aluminium (Al3+), lead (Pb2+) and manganese (Mn2+) ions on calmodulin (CaM)-related Ca2+-ATPase activity in rhesus monkey (Macaca mulatta) brain (RMB). The cerebral cortex of RMB was dissected and homogenized in 10% sucrose buffer, and synaptic plasma membranes (SPM) were prepared. Ca2+-ATPase activity was determined by the inorganic phosphate method.
