BACKGROUND Numerous clinical studies have shown that anti-EGFR therapies are effective only in a subset of patients with colorectal cancer. Mutations in the KRAS and BRAF genes have been confirmed as negative predictors of the response to EGFR-targeted therapies.In this study we evaluated KRAS and BRAF status in 159 colorectal cancer samples obtained from(More)
Other investigations have demonstrated that pressure, exerted by fluid contained within the lumen of the closed neural tube, plays an important role in the morphogenesis of cranial regions of chick embryos. In this study, we investigated whether this pressure is involved also in the formation of the secondary portion of the neural tube--the portion formed(More)
UNLABELLED Neuroendocrine carcinoma of the urinary bladder is a rare entity, accounting less then 1% of urinary bladder malignancies. The vast majority of the neuroendocrine carcinoma of the urinary bladder is represented by small cell neuroendocrine carcinoma while just few cases of large cell neuroendocrine carcinoma (LCNEC) have been reported. In this(More)
Non-small cell lung cancer (NSCLC) is a major public health problem, accounting for more cancer-related deaths than any other cancer. Both immunotherapy, based on the expression of tumor-specific antigens, and targeted therapy, based on the presence of oncogenic mutations, are under development for NSCLC. In this study, we analyzed the expression of MAGE-A,(More)
Fluconazole inhibition of Saccharomyces cerevisiae S288c growth was evaluated in media containing ammonia, L-proline or L-leucine as a nitrogen source. Growth inhibition by fluconazole was maximum when L-proline was used as a nitrogen source, while rhodamine 6G accumulation and fluconazole resistance were the highest when ammonia was the sole nitrogen(More)
Molecular structural characteristics of thyroid hormones which influence binding to the erythrocyte membranes were investigated by competitive binding experiments. The ability of thyroid hormone analogs to displace 131 I-L-thyroxine and 131 I-L-triiodothyronine from the membranes was considered evidence of their competitive binding. The diphenyl ether(More)
Severe mycotic infections are a source of concern in immunocompromised patients or in those who receive chemotherapy for hematological malignant diseases. One of the causes is referred to the appearance of antimycotic resistant microorganisms. Fluconazole is one of the antimycotic used for invasive mycoses treatment. Therefore it is necessary to evaluate(More)
