The class IV semaphorin Sema4A provides a costimulatory signal to T cells. To investigate the possible developmental and regulatory roles of Sema4A in vivo, we generated Sema4A-deficient mice. Although Sema4A-deficient mice develop normally, DCs and T cells from knockout mice display poor allostimulatory activities and T helper cell (Th) differentiation,(More)
Serum PGI2 stabilizing factor (PSF) was purified from human serum to a single protein with a molecular weight of 28,000 D by SDS-PAGE. Analyses of NH2-terminal sequence (32 residues), COOH-terminal sequence (3 residues) and the composition of amino acids disclosed its homology with human apolipoprotein A-I (Apo A-I), a major apolipoprotein of HDL.(More)
Antioxidant activity and biological properties of ferulic acid (FA) are well recognized. This study was designed to estimate the potential utility of FA administered orally at low dosage for improvement of hyperglycemia in diabetes. With this aim we have evaluated the hypoglycemic effect of FA in two type diabetic animal models: (1) streptozotocin(More)
Mice that lack caspase-3, which functions in apoptosis, were generated by gene targeting and shown to undergo hearing loss. The ABR threshold of the caspase-3(-/-) mice was significantly elevated compared to that of caspase-3(+/+) mice at 15 days of age and was progressively elevated further by 30 days. Distortion product otoacoustic emissions were not(More)
BACKGROUND The aim of this study was to investigate the efficacy and safety of high-dose chemotherapy (HDCT) for the treatment of patients with advanced testicular cancer. METHODS Fourteen patients were treated with high-dose carboplatin, etoposide and cyclophosphamide (with or without THP-adriamycin) followed by peripheral blood stem cell(More)
Female rats at 5 days of age were given a single subcutaneous injection of varying doses of danazol or vehicle. Rats treated with 300 micrograms of danazol showed significant (P < 0.01, respectively) advancement in the day of vaginal opening (37.50 +/- 0.49 days vs. 25.20 +/- 0.19 days; mean +/- S.E.M.), first estrus (38.19 +/- 0.62 days vs. 29.10 +/- 0.26(More)
FLT3 is a member of receptor tyrosine kinases expressed in leukemia cells, as well as in hematopoietic stem cells. Recently, a somatic alteration of the FLT3 gene was found in acute myeloid leukemia, as an internal tandem duplication (FLT3/ITD) which caused elongation of the juxtamembrane (JM) domain of FLT3. Here we characterized the FLT3/ITD and(More)
To investigate the prostaglandin I2 (PGI2) half-life regulated by high density lipoprotein (HDL) in patients with coronary artery disease (CAD), we determined the stability of PGI2 and serum apolipoprotein A-I (Apo A-I) and apolipoprotein A-II (Apo A-II) levels in four age-matched groups of patients: controls (n = 17), angina pectoris (n = 18), unstable(More)
BACKGROUND Although laparoscopic technique has become popular in the surgical field, the value of laparoscopy in the removal of adrenal gland is unknown. The objective of this study was to examine the feasibility of laparoscopic adrenalectomy. METHODS Between January 17, 1992, and March 16, 1993, 10 patients (four men, six women; mean, 48.2 years of age)(More)
From January 17, 1992 to January 16, 1993, laparoscopic adrenalectomy was performed in 7 patients (3 men, 4 women) with primary aldosteronism ranging in age from 35 to 65 years (mean 48.7 years). Five of the adrenal lesions were on the left side and two were on the right. Five to six trocar-sheath units were used, and adrenal tumors were successfully(More)
