longitudinal sleep patterns during pubertal growth: four-year follow up.there were little or no indications of differences in sleep outcomes between the sexes. results indicate a disturbance of sleep on initial laboratory nights relative to later nights. the results reported here clearly document the persistence of these effects from year to year. for the most part, sleep characteristics during the 4 years immediately after onset of puberty appear to represent a typical phase in the gradual patterns of changes across all ages. total sleep time decreased markedly fro ...1990171619
increased risk of endometrial carcinoma among users of conjugated estrogens.the possibility that the use of conjugated estrogens increases the risk of endometrial carcinoma was investigated in patients and a twofold age-matched control series from the same population. conjugated estrogens (principally sodium estrone sulfate) use was recorded for 57 per cent of 94 patients with endometrial carcinoma, and for 15 per cent of controls. the corresponding point estimate of the (instantaneous) risk ratio was 7.6 with a one-sided 95 per cent lower confidence limit of 4.7. the r ...1990171569

analysis of 1089 cases of head injury.1089 patients treated for head injuries at the unversity of nigeria teaching hospital, enugu, are analysed. seventy-two percent of them were males. the age group 20-30 years was most vulnerable, accounting for 32% of the total. road traffic accidents were responsible for a staggering 80% of the total. most of the children in this group were pedestrians hit by vehicles on the roads. about 42% of the head injuries were complicated, but the incidence of intracranial haematoma was only 1.3%. the mor ...200197952
exercise and asthma: overview and clinical impact.the question of the relationship between exercise and asthma dates back to the second century a.d. and was not resolved until r.s. jones and co-authors in 1962 reported that there were in reality two effects on the asthmatic patient from exercise depending on the duration of the exercise. short-term exercise of less than four minutes resulted in bronchodilatation, whereas longer-term exercise resulted in bronchoconstriction. exercise-induced bronchospasm occurs in all ages but is more common in ...20021187272
conservative management of low back pain.with the apparent indefinite postponement of the release of chymopapain for lumbar disk disorders, it seems appropriate to review critically the proliferation of proposed methods of management of this common complaint, particularly the numerous exercise regimens which have been set forth as helpful. a critical review of these regimens quickly reveals that the majority are propounded with considerably more confidence than statistical proof of their efficacy. the following is a delineation of the ...2002130680
gtp-binding membrane proteins in activated and differentiating t cells.we have earlier reported changes in the gtp binding of several membrane proteins including gs alpha and gi alpha during thymic differentiation of t cells. using an [alpha-32p]gtp-photoaffinity labeling technique we have studied the pattern of gtp binding proteins in activated and resting t lymphocytes and in t cells induced to differentiate by tpa. the gtp binding proteins in mitogen-activated t cells resembled those seen in leukemia t cell lines. treatment of jurkat, but not of ccrf-cem, t cell ...20021906270
