Prediction of strength and strain of the proximal femur by a CT-based finite element method.
Hip fractures are the most serious complication of osteoporosis and have been recognized as a major public health problem. In elderly persons, hip fractures occur as a result of increased fragilityExpand

Decreased serum levels of D-serine in patients with schizophrenia: evidence in support of the N-methyl-D-aspartate receptor hypofunction hypothesis of schizophrenia.
BACKGROUND The hypofunction of the N-methyl-D-aspartate (NMDA) subtype of glutamate receptors has been implicated in the pathophysiology of schizophrenia. Several lines of evidence suggest thatExpand

Emergence of d-aspartic acid in the differentiating neurons of the rat central nervous system
The rat embryonic brain was probed with anti-d-aspartic acid (d-Asp) antiserum at different stages of development. At gestational day (E) 12, weak immunoreactivity (IR) of d-Asp was apparent at theExpand

Amelioration of vascular endothelial dysfunction in obstructive sleep apnea syndrome by nasal continuous positive airway pressure--possible involvement of nitric oxide and asymmetric NG,
BACKGROUND Asymmetric NG,NG-dimethylarginine (ADMA) is an endogenous inhibitor of endothelial nitric oxide (NO) synthase and its plasma concentration is elevated in patients with cardiovascular riskExpand

Fluorimetric determination of secondary amino acids by 7-fluoro-4-nitrobenzo-2-oxa-1,3-diazole
The fluorigenic reaction of proline with 7-fluoro-4-nitrobenzo-2-oxa-l,3-diazole (NBD—F) is superior, in terms of reactivity and fluorescence yield, to the reactions with the analogous 7-chloro andExpand

Determination of serum d-lactic and l-lactic acids in normal subjects and diabetic patients by column-switching HPLC with pre-column fluorescence derivatization
Abstractd-Lactic and l-lactic acids were simultaneously determined by means of a column-switching high-performance liquid chromatography (HPLC) with fluorescence detection. As a fluorescence reagent,Expand

An HPLC assay of hydroxyl radicals by the hydroxylation reaction of terephthalic acid.
An HPLC assay for hydroxyl radicals is described. The hydroxyl radical was trapped by terephthalic acid (non-fluorescent), and 2-hydroxyl terephthalic acid (fluorescent) was quantitated byExpand

Determination of fluoxetine and norfluoxetine in rat plasma by HPLC with pre-column derivatization and fluorescence detection.
Both fluoxetine (FLX) and its N-demethylated metabolite, norfluoxetine (NFLX), have been reported to be potent serotonin-reuptake inhibitors. A sensitive and reliable method that allows simultaneousExpand

Inactivation and morphological changes of avian influenza virus by copper ions
The infectivity of the H9N2 virus to MDCK cells was time-dependently inhibited by Cu2+ at concentrations of 2.5–250 μM. In 25 μM Cu2+ solution, the virus titer decreased by approximately 3 and 4 logExpand
