The association between elevated levels of low-density lipoprotein (LDL) cholesterol and an increased risk of premature coronary heart disease (CHD) is well documented. Most clinical laboratories estimate LDL cholesterol concentrations according to the Friedewald formula. It provides a relatively reliable estimate of LDL cholesterol concentration, provided(More)
Reductive N,N-dialkylation of daunorubicin with 2,2'-oxydiacetaldehyde and NaBH3CN occurred in two steps without interruption and with cyclization to form 3'-(4-morpholinyl)-3'-deaminodaunorubicin. This derivative retained the antitumor efficacy of doxorubicin against mouse leukemia P388 but at one-fortieth the dose; hence, it is the most potent(More)
According to recent genome-wide association studies, a number of single nucleotide polymorphisms is reported to be associated with diseases or several clinical markers. Among them, adiponectin (ADIPOQ) and perilipin (PLIN) polymorphisms are major factors of obesity. However, the association between lifestyle factor, these polymorphisms and obesity-related(More)
Synthetic approaches to anthracyclines bearing novel 9-acyl substituents were investigated. Reaction of the lithium enolate of N-(trifluoroacetyl)daunorubicin (9) with methyl iodide in tetrahydrofuran afforded only the 9-propionyl derivative 10 in high yield. Reaction of 10 under identical conditions cleanly afforded the 9-isobutyryl derivative 11.(More)
It has been reported that the existing direct method of high density lipoprotein (HDL) cholesterol measures particles enriched with apolipoprotein E (apoE). The aim of our study was to investigate a new analytical protocol to directly measure HDL cholesterol that eliminates apoE-rich particles. The interactions of four lipoproteins (HDL(3), HDL(2), LDL, and(More)
OBJECTIVE To identify dietary patterns in the current Japanese diet and evaluate the associations between these patterns and Na and K intakes. DESIGN Dietary patterns were extracted by factor analysis from the intakes of food groups assessed with a validated self-administrated diet history questionnaire. Na and K intakes and urinary Na:K were assessed by(More)
A man in his 40s was referred to our hospital with abdominal pain. A gastric submucosal tumor (SMT) was diagnosed nine years previously, but the patient was lost to follow-up. Upon our evaluation, the SMT had enlarged, as demonstrated by esophagogastroduodenoscopy and abdominal computed tomography. Endoscopic ultrasonography revealed a hypoechoic and(More)
