BACKGROUND Several molecular-genetic alterations in breast cancer, including aneuploidy, aberrant expression of p53, c-erbB-2, and EGFR have been associated with poor prognosis in breast cancer particularly in lymph node negative patients. To determine the importance of molecular-genetic factors relative to more traditional surgical-pathologic prognostic(More)

BACKGROUND GST is a family of enzymes that are important in protection of the body against oxidative stress. OBJECTIVES Investigate the association between GSTT1 and GSTM1 polymorphism and hypertension. MATERIALS AND METHODS GSTT1 and GSTM1 genotypes were detected by PCR. The fragments were then analyzed by agarose gel electrophoresis. RESULTS There(More)
The enzyme 5 alpha-reductase (5 alpha R), by virtue of its peripheral 5 alpha-reduction of testosterone (T) to dihydrotestosterone (DHT), is believed to play a major role in the differentiation and the subsequent growth of the penis. However, recent studies have reported 5 alpha R deficiency (5 alpha RD) in patients with isolated micropenis and hypothesized(More)
The X-linked androgen insensitivity syndrome (AIS) encompasses a heterogeneous group of defects in the androgen receptor (AR) that result in varying degrees of undermasculinization. In the current study, we characterize the R840S mutation on exon 7 of the AR ligand-binding domain. The Egyptian patient, who had been reared as female, presented ambiguous(More)
