BACKGROUND Human chorionic gonadotropin/luteinizing hormone (hCG/LH) function in the male is mediated by the LH receptor (LHR) and is crucial for the normal development of internal and external genitalia. We report a 46, XY patient who presented at the age of 16 with a female phenotype and delayed puberty. Gonads were located bilaterally in the inguinal canal, removed surgically and showed hypo...

We have isolated mutants responsible for an oversecretion phenotype in Saccharomyces cerevisiae, using a promoter of SUC2 and the gene coding for alpha-amylase from mouse as a marker of secretion. These mutations defined two complementation groups, designated as ose1 (over secretion) and rgr1 (resistant to glucose repression). The ose1 mutant produced an oversecretion of amylase by 12- to 15-fo...

background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...

Dermatofibrosarcoma protuberans (DFSP) is an aggressive PDGFB-dependent cutaneous sarcoma characterized by infiltrative growth and frequent local recurrences. Some DFSP progress to a higher-grade fibrosarcomatous form, with rapid growth and increased risk of metastasis. Imatinib provides clinical benefit in approximately 50% of patients with unresectable or metastatic DFSP. However, efficacious...

BACKGROUND AND PURPOSE There is a rapid worldwide emergence of multidrug-resistant pathogens, especially in nosocomial isolates. This study compared the in vitro activities of levofloxacin, ciprofloxacin, ceftazidime, cefepime, imipenem, and piperacillin-tazobactam against 208 aerobic bacterial pathogens that caused 197 nosocomial infections in 184 patients. METHODS Antimicrobial susceptibili...

PURPOSE Although 80~90% of patients with lung cancer are smokers, only 11% of smokers develop lung cancer. Genetic susceptibility according to the polymorphism of the epoxide hydrolase (mEPHX) gene and homozygous deletion of GSTM1 (M1 subunit of Glutathione S transferase) was studied in this case control study. MATERIALS AND METHODS Genomic DNA from 76 subjects with lung cancer (40 squamous c...

Although most inbred mouse strains are highly susceptible to mouse hepatitis virus (MHV) infection, the inbred SJL line of mice is highly resistant to its infection. The principal receptor for MHV is murine CEACAM1 (mCEACAM1). Susceptible strains of mice are homozygous for the 1a allele of mCeacam1, while SJL mice are homozygous for the 1b allele. mCEACAM1a (1a) has a 10- to 100-fold-higher rec...
