We studied the expression of peripheral myelin protein 22 (PMP22) gene in the human central nervous system (CNS). Northern blot analysis was performed with polyA+ RNA blots containing several parts of the human brain and the spinal cord using human PMP22 cDNA as a probe. As two alternative PMP22 transcripts have been reported and since exon 1A-containing(More)
Several proximate factors of masting have been provided. Here, I focus on the role of internal factors, especially the relationship between internal carbon resources and modular structures in trees. I summarize various studies of carbon resource allocation for reproduction during masting events in terms of the proximate factors of masting and discuss the(More)
A dramatic rise in the incidence of obesity in the U.S. has accelerated the search for interventions that may impact this epidemic. One recently recognized target for such intervention is adipose tissue, which secretes a variety of bioactive substances including prostaglandins. Prostaglandin E₂ (PGE₂) has been shown to decrease lipolysis in adipocytes, but(More)
To clarify the effects of whole-body vibration (WBV) on visual performance, visual acuity and a self-rated assessment of difficulties in visible perception were determined after various frequencies of vibration in six healthy males. Two different sitting postures, an erect posture and a muscle-relaxed posture, were used. Sinusoidal vertical vibrations at(More)
OBJECTIVES To clarify the mechanism of a human reaction to vibration stress by palmar sweating in relation to the autonomic nerve tone. METHODS The autonomic nerve tone was divided into four types by using digital photoelectroplethysmography (PTG) with auditory stimuli: normal (N), hyperreactive (I and D), and hyporeactive (P) types. Palmar sweating and(More)
Seedling genotype is one of the major factors affecting seedling survival when the rate of damage by natural enemies depends on a host genotype. However, to our knowledge, no previous study has examined the mortality of seedlings adjacent to conspecific adults, considering intraspecific variation in seedling genotypes. On the basis of the assumption that(More)
A Japanese male patient presented with an enormously disfigured penis and scrotum. The penis was swollen and distorted rightward, and the skin was hard and lumpy. The patient had had a subdermal abscess for 6 years. The current condition was considered secondary lymphoedema of the penis and scrotum resulting from chronic skin infection. Wide excision of the(More)
Dendrochronological approaches enable us to understand forest stand dynamics by estimation of disturbance history and age structure. The present study was conducted in an old-growth beech forest in a forest reserve in western Japan. Increment cores were taken for tree ring analysis from all canopy trees in a 50 m × 130 m study plot. Radial growth release(More)
Air embolism is a rare, but occasionally fatal complication of peripheral and central venous catheterization. We present a case of an 89-year-old female, who had a central venous catheter placed in her right jugular vein during the perioperative period for right femoral subtrochanteric fracture. On the day following her operation, level of consciousness(More)
