— To extend an available period of wireless sensor networks, transmission power control is regarded as one of the promising schemes. In most of the previous studies on the transmission power control, it is assumed that a transmitter has power consumption of O(d n), where d and n denote a maximum communication distance and a pass loss factor. This assumption(More)
The recessive mutant mouse jumonji (jmj), obtained by a gene trap strategy, shows neural tube defects in approximately half of homozygotes with a Balb/cA and 129/Ola mixed background. Here, we show that no neural tube defects are observed with a Balb/cA background. We also found hypoplasia of the liver, thymus and spleen with full penetrance with a Balb/cA(More)
The recessive mutant mouse jumonji (jmj), obtained by a gene trap strategy, shows neural tube defects in approximately half of homozygous embryos with a BALB/cA and 129/Ola mixed background, but no neural tube defects with BALB/cA, C57BL/6J, and DBA/2J backgrounds. Here, we show that neural tube and cardiac defects are observed in all embryos with a C3H/HeJ(More)
We examined the anti-stress action of the essential oils of lavender, rose, and lemon using an elevated plus-maze task (EPM), a forced swimming task (FST), and an open field task (OFT) in mice. Lemon oil had the strongest anti-stress effect in all three behavioral tasks. We further investigated a regulatory mechanism of the lemon oil by pre-treatments with(More)
To determine whether docosahexaenoic acid (DHA) affects stress responses in rats, we investigated its influence on several behavioral tests. Female rats were fed a diet deficient in (n-3) fatty acid from mating through pregnancy and lactation. Male pups fed the same diet as their dams were used for experiments. The effects of dietary (n-3) fatty acid(More)
IMPORTANCE No highly effective interventions to prevent delirium have been identified. OBJECTIVE To examine whether ramelteon, a melatonin agonist, is effective for the prevention of delirium. DESIGN, SETTING, AND PARTICIPANTS A multicenter, rater-blinded, randomized placebo-controlled trial was performed in intensive care units and regular acute wards(More)
During development of the mouse central nervous system (CNS), most neural progenitor cells proliferate in the ventricular zone (VZ). In many regions of the CNS, neural progenitor cells give rise to postmitotic neurons that initiate neuronal differentiation and migrate out of the VZ to the mantle zone (MZ). Thereafter, they remain in a quiescent state. Here,(More)
Prosaposin (PSAP) is as a trophic factor and an activator protein for sphingolipid hydrolase in lysosomes. We generated a specific antibody to PSAP and examined the spatiotemporal distribution of PSAP-immunoreactive (PSAP-IR) cells in the lymphatic tissues of Wistar rats. Immunoblots of tissue homogenates separated electrophoretically showed a single band(More)
Lactoferrin (LF) is known as an iron-binding glycoprotein. It has been shown that bovine LF (bLF) is transported into cerebrospinal fluid via blood although its physiological effects in the central nervous system (CNS) are still unclear. In this study, a suppressive effect of bLF on psychological distress was investigated in adult rats. Intraperitoneal(More)
A typical oxidative DNA damage, 8-hydroxydeoxyguanosine (8-OHdG), was evaluated in human polymorphonuclear leukocytes (PMN) and mononuclear leukocytes (MN) by an anaerobic determination method. The mean 8-OHdG values were the lowest level ever reported [PMN, 3.07 +/- 1.45; MN, 2.37 +/- 1.21 8-OHdG/10(6) deoxyguanosine molecules (dG); n = 92]. According to a(More)
