INTRODUCTION The purpose of this study was to investigate the efficacy and safety of L-theanine as an aid to the improvement of objectively measured sleep quality in a population of 98 male children formally diagnosed with attention-deficit/hyperactivity disorder (ADHD). METHODS A randomized, double-blind, placebo-controlled trial was conducted involving boys, ages 8-12 years, who had been pr...

a liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for k ion in transport while diethylene glycol dibutyl ether (1) was selective for na over k . as an extractant, ligand 2 exhibited pronounced extraction selectivity for k over na in comparison with ligand 1

Gabapentin is an anticonvulsant widely used in the treatment of epilepsy. No peculiar chromophore is available on the gabapentin moiety for direct analysis by absorption spectrophotometry. A sensitive spectrophotometric method for the determination of gabapentin in bulk, pharmaceutical formulations and human plasma has been developed. In this method, gabapentin directly derivatized with vanilli...

We report diffusion coefficients of micron-scale liquid domains in giant unilamellar vesicles of phospholipids and cholesterol. The trajectory of each domain is tracked, and the mean square displacement grows linearly in time, as expected for Brownian motion. We study domain diffusion as a function of composition and temperature and measure how diffusion depends on domain size. We find mechanis...

Hollow fiber liquid phase micro-extraction (LPME) of linear alkylbenzene sulfonates (LAS) from aqueous samples was studied. Ion pair extraction of C10, C11, C12 and C13 homologues was facilitated with trihexylamine as ion-pairing agent, using di-n-hexylether as solvent for the supported liquid membrane (SLM). Effects of extraction time, acceptor buffer concentration, stirring speed, sample volu...

l-Theanine is a nonprotein amino acid with much beneficial efficacy. We found that intraperitoneal treatment of the mice l-theanine (100 mg/kg/day) enhanced adaptive thermogenesis and induced browning inguinal white adipose tissue (iWAT) elevated expression Prdm16, Ucp1, other thermogenic genes. Meanwhile, administration increased energy expenditure. In vitro studies indicated development brown...

Tea (Camellia sinensis) is widely considered to promote feelings of calming and soothing. This effect attributed L-theanine (L-?-glutamylethylamide) in tea, a non-protein amino acid mainly derived from tea leaves. As naturally occurring structural analogue glutamate, competes for the receptors with glutamate able pass blood-brain barrier exert its relaxation effect. review focuses on L-theanine...
