The authors’ purpose in this study was to identify social structural predictors of receiving emotional support from parents early in life and structural factors responsible for variations in the associations between early parental support and adult health status. Data from a US representative sample of 2,786 adults aged 25–74 years suggest that men, non-Whites, and individuals from socioeconomi...

7 9As. The 7 9As was prepared by irradiating metalic Se (enriched to 97 .8% in 8 0Se) in the linear accelerator of the C.B.P.F. The maximum energy of the bremsstrahlung beam was 22 MeV and irradiations were performed using up to 600 mg samples with irradiation times up to 30 min. The gamma-ray spectra were detected by a 2 cm 3 Ge(Li) diode. The pulses were fed via an O R T E C 1 0 9 preamplifie...

Reactive oxygen species are known to be potentially dangerous, but are also needed for signal-transduction pathways. Tumor cells have relatively low amounts of superoxide dismutase (SOD), which quenches superoxide anion (O2 •), and as a result of a higher level of aerobic metabolism, higher concentrations of O2 •, compared to normal cells. But this may not be true of all tumor cells. Some tumor...

The effect of mechanical damage on the composition of the essential oil obtained from eugenol-rich Ocimum minimum leaves was determined over 48 hours. Changes in the levels of five oil-constituents were detected in the first post-wounding day but only one of those components (camphor) exhibited the same behaviour the day after. The levels of eugenol (-4.8%) and linalool (+2.5%) were affected th...

The incidence of pyogenic arthritis is less than that of transient synovitis and varies substantially (from 1/100,000 to 37/100,000 children) depending on the population studied. Although pyogenic arthritis occurs in all age groups, the peak incidence of disease is in children under 3 years of age. A history of trauma temporally related to the onset of arthritis caused by Staphylococcus aureus ...
