L-theanine partially counteracts caffeine-induced sleep disturbances in rats.

L-theanine has been reported to inhibit the excitatory effects of caffeine. The present study examined the effects of L-theanine on caffeine-induced sleep disturbances in rats. Rats received the following drug pairings: saline and saline (Control), 7.5 mg/kg caffeine and saline, or 7.5 mg/kg of caffeine followed by various doses of L-theanine (22.5, 37.5, 75, or 150 mg/kg). Vigilance states wer...

Heterozygote Detection

saemia in a British hospital, with emphasis on heterozygote detection. Results are reported of a screening programme for galactosaemia covering a period of 2A years and 6415 births. The gene frequency for galactosaemia estimated from the data of the screening programme was 0-002. This conflicted with the known livebirth incidence of at least 1: 50,000 during this same period. 2 of the 4 galacto...

Dietary supplementation with l-arginine partially counteracts serum metabonome induced by weaning stress in piglets.

Arginine plays an important role in preventing intestinal dysfunction and metabolic disorders caused by early weaning stress. However, little is known about how arginine mitigates early weaning stress. This study was conducted to evaluate the effects of weaning stress and dietary arginine supplementation on the metabonome in the serum of piglets using (1)H NMR spectroscopy in conjunction with m...

Large Lepton Mixings Induced by Sterile Neutrino

We assume that the mass matrix of active neutrinos has hierarchical form with small mixings, similar to quark mass matrix. We show that the large mixings between ν µ and ν τ as well as between ν e and certain combination of ν µ and ν τ required by the present data can appear due to the presence of a sterile neutrino state. Two realizations of this possibility are considered: (i) Large flavor mi...
