The CYP17 gene encodes the enzyme cytochrome P450c17alpha, which mediates both 17alpha-hydroxylase and 17,20-lyase activity in the steroid biosynthesis pathway. A T-->C polymorphism in the 5' promoter region of CYP17 has been described. To examine the association between recurrent pregnancy loss (RPL) and a polymorphism in CYP17, a case-control study of 117(More)
The etiology of recurrent pregnancy loss (RPL) remains unclear, but it may be related to a possible genetic predisposition together with involvement of environmental factors. We examined the relation between RPL and polymorphisms in four genes, human aryl hydrocarbon (Ah) receptor, cytochrome P450 (CYP) 1A1, CYP1A2 and CYP1B1, which are involved in the(More)
The purpose of the present study was to report cases of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI)-naïve patients carrying a mutation associated with acquired resistance to the drug. Gene alterations in 77 lung carcinoma patients were analyzed by collecting and studying curette lavage fluid at the time of diagnosis. PCRs were(More)
To examine the relationship between dose distribution and tumor shrinkage of acoustic neurinomas, correlation coefficients between distribution probabilities of some dose areas and residual tumor ratios of 21 cases were studied at 2 years. Approximating a dose-volume histogram to beta-distribution, two essential dose areas for tumor control were extracted:(More)
An 18-month-old boy was diagnosed as having a hypothalamic hamartoma. When he was 1 year old, he developed precocious puberty, and at 18 months old, endocrinological tests revealed abnormally high follicle-stimulating hormone, luteinizing hormone, and testosterone levels. The center of the hamartoma was subtotally excised, as confirmed on the postoperative(More)
