Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a heterogeneous enzyme abnormality with high frequency in tropical areas. We performed population screening and molecular studies of G6PD variants to clarify their distribution and features in Southeast Asia. A total of 4317 participants (2019 males, 2298 females) from 16 ethnic groups in Myanmar, Lao(More)
Urinary metabolites of α-pyrrolidinovalerophenone (α-PVP) in humans were investigated by analyzing urine specimens obtained from abusers. Unambiguous identification and accurate quantification of major metabolites were realized using gas chromatography–mass spectrometry and liquid chromatography-tandem mass spectrometry with newly synthesized authentic(More)
OBJECT The Matrix detachable coil is a new bioactive, bioabsorbable coil used in the endovascular embolization of intracranial aneurysms. It has a platinum core covered with a bioactive, bioabsorbable polymer (polyglycolic acid/lactide). The authors report on their initial midterm clinical experience with the first-generation Matrix detachable coil. (More)
Experimental Angiostrongylus costaricensis infection was carried out in inbred strains of mice (C57BL/6 BALB/c, DBA/2 and C3H/He). All strains became infected with this parasite. Marked differences in mortality and in worm burden were found among inbred strains of mice tested. A significant reduction was shown in worm length from mice compared to that from(More)
PURPOSE Estrogen receptor-alpha (ER-alpha) and -beta (ER-beta) play important roles in the carcinogenesis of breast tumors. Similarly, there have been several reports of ER expression in lung cancers, but the results have not been consistent, and the receptors' prognostic value remains unclear. Our goal was to investigate ER expression in non-small cell(More)
The aim of this review is to present the chemical aspects, pharmacology, acute toxicities, and metabolisms of α-pyrrolidinophenone derivatives, a new group of synthetic cathinones. Compared to other synthetic cathinones, α-pyrrolidinophenone derivatives have high lipophilicity due to the pyrrolidine ring substitution at the nitrogen atom, resulting in(More)
BACKGROUND The aim of the present study was to determine the prognostic significance of the combined overexpression of epidermal growth factor receptor (EGFR) and estrogen receptor a (ER-alpha) in non-small cell lung cancer (NSCLC). PATIENTS AND METHODS An immunohistochemical assessment of EGFR and ER-alpha expression was carried out in tumor specimens(More)
We applied remote sensing using satellite images capable of obtaining data over a broad range, transcending national borders, as a method of rapidly, precisely, and safely increasing our understanding of the potential distribution of malaria. Our target region was the so-called Mekong malaria region on the Indochina Peninsula. As a malaria index, we used(More)
We have used functional magnetic resonance imaging to study the neural correlates of motivation, concentrating on the motivation to learn and gain monetary rewards. We compared the activation in the brain obtained during reported high states of motivation for learning, with the ones observed when the motivation was based on monetary reward. Our results show(More)
Mass spectrometric differentiation of the six isomers of mono-methoxyethylamphetamines (MeO-EAs) and mono-methoxydimethylamphetamines (MeO-DMAs) by gas chromatography–electron ionization–tandem mass spectrometry (GC–EI–MS–MS) was investigated. Based on their EI-mass spectra, the fragment ions at m/z 121 and 72 were selected as precursor ions for their(More)
