In this study, we performed a screening of the specificities of rat cytochrome P450 (CYP) isoforms for metabolic reactions known as the specific probes of human CYP isoforms, using 13 rat CYP isoforms expressed in baculovirus-infected insect cells or B-lymphoblastoid cells. Among the metabolic reactions studied, diclofenac 4-hydroxylation (DFH),(More)
The growth of plants depends on continuous function of the meristems. Shoot meristems are responsible for all the post-embryonic aerial organs, such as leaves, stems and flowers. It has been assumed that the phytohormone cytokinin has a positive role in shoot meristem function. A severe reduction in the size of meristems in a mutant that is defective in all(More)
Recent studies of highly branched mutants of pea, Arabidopsis and rice have demonstrated that strigolactones (SLs) act as hormones that inhibit shoot branching. The identification of genes that work downstream of SLs is required for a better understanding of how SLs control the growth of axillary buds. We found that the increased tillering phenotype of fine(More)
Sex-determining mechanisms are diverse among animal lineages and can be broadly divided into two major categories: genetic and environmental. In contrast to genetic sex determination (GSD), little is known about the molecular mechanisms underlying environmental sex determination (ESD). The Doublesex (Dsx) genes play an important role in controlling sexual(More)
In rice panicle development, new meristems are generated sequentially in an organized manner and acquire their identity in a time- and position-dependent manner. In the panicle of the panicle phytomer2-1 (pap2-1) mutant, the pattern of meristem initiation is disorganized and newly formed meristems show reduced competency to become spikelet meristems,(More)
BACKGROUND We showed previously that subclinical low-risk papillary thyroid microcarcinoma (PTMC) could be observed without immediate surgery. Patient age is an important prognostic factor of clinical papillary thyroid carcinoma (PTC). In this study, we investigated how patient age influences the observation of low-risk PTMC. METHODS Between 1993 and(More)
Regional activation of the brain was studied in humans using functional magnetic resonance imaging during whole body cooling that produced thermal comfort/discomfort. Eight normal male subjects lay in a sleeping bag through which air was blown, exposing subjects to cold air (8 degrees C) for 22 min. Each subject scored their degree of thermal comfort and(More)
The cribriform-morular variant (CMV) of papillary thyroid carcinoma (PTC) is a rare histologic subtype of PTC that shows a combination of growth patterns including cribriform and spindle cell areas. The thyroid cancer with this unique histology was originally reported in patients with familial adenomatous polyposis (FAP), although it was later found in(More)
OBJECTIVES SLCO1B1*5 and SLCO1B1*15 have been reported to reduce the clearance of pravastatin in healthy volunteers. However, there remains controversy in the effects of SLCO1B1*5 on the activity of OATP1B1 in vitro. In addition, the effect of SLCO1B1*15 on the function of OATP1B1 has not been studied using cDNA-expression systems. Object of the present(More)
The recent prevalence of ultrasound-guided fine-needle aspiration biopsy has resulted in a marked increase in the number of patients with papillary microcarcinoma (maximum diameter, </= 10 mm) of the thyroid detected by this sophisticated tool. On the other hand, it is debatable whether patients with papillary microcarcinoma should always undergo surgery(More)
