This study collected data on rates of cigarette smoking in the following Pacific Islands: Cook Islands, Fiji, Kiribati, Nauru, New Caledonia, Niue, Tuvalu, and Western Samoa. The data were collected in 1975-81 as part of a diabetes-cardiovascular diseases survey. A large variation in the prevalence of smoking was found in the populations surveyed. 90%(More)
Incubation of washed human sperm with [3H]- or [14C]arachidonic acid allowed a major incorporation of the label into phospholipids, provided that the final concentration of the fatty acid did not exceed 20 microM. A further challenge with calcium ionophore A23187 of spermatozoa suspended in a calcium-containing medium led to phospholipid hydrolysis, which(More)
The metabolic effects of four oral contraceptives with different estrogen/progestogen profiles (monophasic nonalkylated estrogen/norethindrone, low-dose monophasic ethinyl estradiol (EE2)/norethindrone, progestogen only treatment with norethindrone, and triphasic EE2/levonorgestrel) were examined in insulin-dependent diabetic women. During the 6-month study(More)
Human sperm lysates were incubated in the presence of 1-[14C]stearoyl-2-acyl-sn-glycero-3-phosphocholine, 1-[14C]stearoyl-2-acyl-sn-glycero-3-phosphoethanolamine or 1-[14C]stearoyl-2-acyl-sn-glycero-3-phosphoinositol. Only the latter substrate was hydrolyzed to a significant extent, with a concomitant formation of 1-[14C]stearoyl-2-acyl-sn-glycerol.(More)
PCR and culturing were compared for the routine diagnosis of Chlamydia trachomatis infections. Two laboratories experienced in both techniques participated in the study, which included 513 specimens. Both techniques were performed on each specimen; the portion of the specimen used for PCR was divided in two, and each half was sent to one of the two(More)
BACKGROUND Of all of the lower-extremity injuries with multifactorial causes, heel pain represents the most frequent reason for visits to health-care professionals. Managing patients with heel pain can be very difficult. The purpose of this research was to identify key variables that can influence foot health in patients with heel pain. METHODS A(More)
An electrical and physical design power optimization methodology and design techniques developed to create an ARM 1136SF-S microprocessor in 9Onm standard CMOS are presented. A 40% reduction in power dissipation has been achieved while maintaining a 355 MHz operating clock rate under typical conditions. Functional and electrical design requirements were(More)
We have devised a new enzymatic determination of sn-glycero-3-phosphocholine (GPC) in human seminal plasma. This is based on GPC hydrolysis by a phosphodiesterase (PDE), free choline being then determined by the choline oxidase method. The whole procedure involves a first incubation in the presence of choline oxidase and catalase, to eliminate the excess of(More)
