AIMS To estimate the prevalence of passive smoking at work in the whole workforce in Hong Kong (population 6.8 million), the characteristics of the passive smokers, any extra use of health care among passive smokers, and who pays for that health care. METHODS A random sample of 14,325 households was contacted by telephone; 6,186 responding adults who worked full time were asked about their em...

the effect of anti-follicular stimulating hormone (fsh) on testicular lipid and the specific activity of testicular enzymes of the isocitrate dehydrogenase (icdh), pyruvate/malate dehydrogenase (mdh) and malic enzyme involved in lipogenesis were studied in mature bonnet monkeys, macaca radiata. immunization of monkey with anti-fsh for 24 days did not produce any significant changes in the body ...

introduction: cholinergic systems are involved in learning and memory. scopolamine, a muscarinic acetylcholine receptor antagonist, is used as a standard/ reference drug for inducing cognitive deficits in healthy humans and animals. the purpose of this study was to evaluate the effects of scopolamine on avoidance memory and number of neurons in rat’s hippocampus. . methods: thirty five male alb...

background: it has been reported that epilepsy is a disorder of the central nervous system that causes memory impairment. this study examines the role of the aqueous extract of boswellia on the learning disability of the pentylenetetrazol (ptz)‑induced kindled rats. methods: in this experimental study, 64 male rats were used. kindling seizures were induced by three injections of 25 mg/kg of ptz...

introduction:with increasing threats of weapons of mass destruction (wmd) in future war especially biological threats against our country necessity of using novel technologies in crisis management against new warfare’s is very important. passive defense as a peaceful and preventive strategy without any warfare is able to not only monitor the prospect of new warfare specially biological warfare ...

in this paper, the electrochemical behaviour of passive films formed on aisi 321 stainless steel (aisi 321)immersed in 0.1 m naoh + 0.1 m koh solution was evaluated by different electrochemical techniques. forthis purpose, passive films were formed at open circuit potential for 1 to 12 hours and then electrochemicalmeasurements were done. the polarization curves suggested that aisi 321 showed e...

This study was aimed at understanding the relationship among menstrual pattern, dysmenorrhea, life style and working conditions in nurses. The nurses were randomly selected from a medical center in Northern Taiwan. Each subject completed daily records including life and working conditions during the study period. The study showed that there were statistically significant differences in work yea...

ATP repletion following exhaustive exercise is approximated to be 90-95% complete in 3 minutes, and is crucial in the performance of short duration, high intensity work. Few studies appear to have used this 3-minute interval in the investigation of recovery modes, blood lactate accumulation and power output. Thus, our aim was to investigate changes in peak power (PP), average power (AP) and blo...

BACKGROUND The isokinetic dynamometer has been considered the gold-standard measurement of muscle performance. However, the reliability for the passive mode in children has not been reported to date. OBJECTIVES The purpose was to evaluate the reliability of the isokinetic dynamometer in passive mode in children. METHOD Twenty-one healthy children (ten girls, eleven boys), aged 5 to 12 years...
