Effect of sustained typing work on changes in scapular position, pressure pain sensitivity and upper trapezius activity.
We observed that sustained computer work changed the scapular position in the stretched upper trapezius. To prevent musculoskeletal problems in the shoulder region, posture reeducation during computer work should be considered in terms not only of neck and trunk posture, but also of scapular positio...
Associations of work hours and actual availability of weekly rest days with cardiovascular risk factors.
We used data from checkups conducted in 1999 and 2006 for 30,194 men who worked for a local public institution in Japan. We calculated the cumulative incidence rates of onset of obesity, hypertension, hyperglycemia, hypertriglyceridemia and low HDL cholesterol over this 7-year period and performed a...
Occupational exposure to phenolic compounds at coke plants--urinary excretion of methoxyphenols as an indicator of exposure to methoxyphenol...
The time-weighted average concentrations (median) of methoxyphenols in the breathing zone air were as follows: 9.9 ng/m(3), 15.4 ng/m(3) and 92.5 ng/m(3) for 2-methoxyphenol, 2-methoxy-4-methylphenol and 1-(4-hydroxy-3-methoxyphenyl)ethanone, respectively. The median values of urinary concentrations...
Change in coping strategies following intensive intervention for special-service military personnel as civil emergency responders.
With the combined use of modular contents and procedural methods, our intervention not only led to fewer choices of immature coping strategies like fantasy, escape and rationalization, but also raised the use of mature coping strategies such as problem-solving and help-seeking. Accordingly, the inte...
Cell injuries of the blood-air barrier in acute lung injury caused by perfluoroisobutylene exposure.
I epithelial cells, alveolar type II epithelial cells and pulmonary microvascular endothelial cells were observed at 30 min post PFIB exposure. Some injuries were similar to apoptosis. Compared with control, more serious injuries were observed in PFIB-exposed rats after 30 min. At 8 h, some signs of...
Prevalence and associated factors for thoracic spine pain in the adult working population: a literature review.
The high median prevalence rates suggest TSP may be a significant occupational health problem. The multiple domains of associated factors point to the need for prospective research encompassing these domains to inform targeted occupational interventions....
Effects of chronic noise exposure on spatial learning and memory of rats in relation to neurotransmitters and NMDAR2B alteration in the hipp...
The purpose of this study was to examine the effects of noise exposure on spatial learning and memory and associated mechanisms in the hippocampus (HIP). Forty-eight male SD rats were grouped as: A, control; B, Morris water maze (MWM) training group; C, noise exposure group; and D, noise exposure fo...
Effect of nursing assistance tools on preventing musculoskeletal pain among staff in schools for disabled children.
We investigated the one-month prevalence of low back pain and the degree of burden on the lower back using a questionnaire at the baseline and at the end point 4 to 6 months later. The prevalence of low back pain did not change significantly in either group. In the intervention group, the prevalence...
Reliability and validity of the Japanese version of the Stanford Presenteeism Scale in female employees at 2 Japanese enterprises.
Detection of mutant p53 protein in workers occupationally exposed to benzidine.
We detected mutant p53 protein by immuno-PCR assay in the serum of 331 benzidine-exposed healthy workers, while we classified exfoliated urothelial cells in urine samples with Papanicoloau's grading (PG). The Papanicoloau's grading classified exfoliated urothelial cells of the subjects from grade I...
