BACKGROUND Preclinical data indicate that p-53 gene mutations predict resistance to doxorubicin (A) but not to docetaxel (Taxotere) (T). In the TAX 303 trial, A and T have been compared with advanced breast cancer patients. PATIENTS AND METHODS Primary tumor samples from patients participating in the TAX 303 trial were collected. p-53 gene mutations were evaluated by denaturing high-performan...
PURPOSE PAX6 mutations cause aniridia as well as other various congenital eye abnormalities. Aniridia can be due to both point mutations and chromosomal deletions/rearrangements. Therefore, a complete search for PAX6 gene alterations in aniridia subjects requires a technically complex approach involving the comprehension of fluorescence in situ hybridization (FISH) analysis. In the present stud...
Denaturing High-Performance Liquid Chromatography (DHPLC) is a recently developed technique forthe detection of single nucleotide polymorphisms (SNPs) and mutations. It involves the comparisonbetween two or more DNAs as a mixture of denatured and reannealed PCR products. The methodologyis based on the principle of reversed phase liquid chromatography and uses a unique DNA sepa...
OBJECTIVES To establish the prevalence and diversity of clinically significant extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae harbouring bla(CTX-M) in the West Midlands region of the UK. METHODS During a 2 month period, 370 consecutive, non-duplicate isolates were collected from 13 laboratories. Isolates were screened for the presence of bla(CTX-M) by multiplex PCR and geno...
