current issues in perinatal epidemiology.the main national data sources for perinatal epidemiology are birth and death certificates, yet routinely linked birth and death certificate data are still not available in the u.s. completeness and quality of the reporting of perinatal events should be considered in examining trends over time and between jurisdictions. the u.s. has experienced a marked decline in its infant mortality rate, but only a very modest decline in the rate of low birth weight. research must focus more on studies of pre ...20123660860
[effect of body position on the ability to initiate paroxysmal supraventricular reentry tachycardias and on the conduction system properties of the reentry circuit].the obtainability as well as the maintenance and termination of paroxysmal supraventricular reentry tachycardias depend upon the interaction of the individual components of the reentry circle, in which cases the properties of the pathway are influenced by the changing preponderance of the sympathetic and parasympathetic tonus and thus also by the body position. in 29 investigations by means of highly frequent and programmed transoesophageal atrial stimulation the influence of the body position o ...20133660882
influence of nifedipine on arterial baroreflex modulation of heart rate control during dynamic increases in arterial pressure: studies in normal man.studies in animals have demonstrated that calcium channel blocking agents exert important influences on autonomic mechanisms in addition to their direct vascular effects. previous studies in our laboratory showed that clinical doses of nifedipine sensitized baroreceptor-mediated control of peripheral vascular resistance in normal human subjects. however, baroreflex control of vascular tone does not necessarily imply parallel control of heart rate. a series of experiments was therefore performed ...19873661368
[volatile anesthetics and n-alcohols inhibit the uptake of noradrenaline in pheochromocytoma cells].studies with perfused animal organs did not show a significant inhibition of the norepinephrine uptake by volatile anesthetics however, the uptake of norepinephrine into isolated chromaffin granules proved to be halothane-sensitive , and there is indirect evidence for an inhibition of norepinephrine uptake by halothane in the dog saphenous vein. so far no literature is available on norepinephrine uptake into cultured cells in the presence of volatile anesthetics. the rat pheochromocytoma cell li ...19873661947

swimming experiences and abilities of nine year olds.as part of a longitudinal study of children, 941 mothers were asked to report on their childrens' swimming experiences and abilities. at age nine, twenty-nine per cent of the children could swim only a few strokes or not at all. a disproportionate number of children who could swim more than a few strokes came from high socio-economic backgrounds, from families where one or more of the parents could swim, and which scored higher on an index of active recreational orientation. there were no signif ...20133697602
spinal cord serotonin release and raised blood pressure after brainstem kainic acid injection.the recently developed technique of in vivo dialysis has permitted us to make direct measurements of serotonin release in a specific region of the spinal cord and to relate this to changes in blood pressure elicited by chemical stimulation of the brainstem. in the present experiments we have shown that chemical stimulation of bulbospinal neurons in the region of the b3 cell group in the ventromedial medulla, causes an increase in the release of serotonin in the thoracic spinal cord and that this ...19863697690
evidence for the presence of a novel biosynthetic pathway for norspermidine in vibrio.enzymatic studies of the cell extracts of vibrio alginolyticus and v. parahaemolyticus provided evidence that there exists a novel biosynthetic pathway for norspermidine (nh2(ch2)3nh(ch2)3nh2), a major polyamine species. in this pathway, the schiff base formed between aspartic beta-semialdehyde and 1,3-diaminopropane is first reduced by a nadph-dependent enzyme to yield "carboxynorspermidine" (nh2(ch2)3nh(ch2)2ch(nh2)cooh), which is in turn decarboxylated by a pyridoxal phosphate dependent enzym ...19863697846
rate of incorporation of [3h]thymidine in various tissues of the mouse. a basis for the evaluation of genotoxic effects of chemicals.[3h]thymidine has been extensively used as a selective precursor to dna in studies on the kinetics of cell proliferation. we have become interested in measuring early inhibition of the dna synthesis in various organs of intact animals for detecting genotoxic properties of chemicals. such experiments should, for convenience and to achieve a large capacity, be performed in the simplest way possible. the present paper deals with some practical aspects on the use of [3h]thymidine in vivo.
