The involvement of Aurora-A and p53 in oxaliplatin-resistant colon cancer cells.

Resistance to chemotherapy is the deadlock in cancer treatment. In this study, we used wild-type LOVO (LOVO ), a human colon cancer cell line, and the oxaliplatin-resistant sub-clone LOVO cells to investigate the molecular mechanisms of the development of drug resistance in colon cancer. Compared with LOVO cells, LOVO cells had a high proliferation capacity and a high percentage on the G2/M phase.

Incidental finding of situs ambiguus in a middle-aged woman.

Situs ambiguus is a rare congenital abnormality with outcomes ranging from asymptomatic to fatal. Here we present a woman with an incidental finding of situs ambiguus hinted by her chest radiograph. This case highlights the importance of actively seeking diagnosis when right sub-diaphragmic air is noted when viewing a chest radiograph.

Pharmacogenetic study of methadone treatment for heroin addiction: associations between drug-metabolizing gene polymorphisms and treatment efficacy.

Objectives: Opioid dependence is currently one of the most serious problems affecting the social norms and public health system. Methadone maintenance therapy (MMT) is being widely used in treating heroin-dependent patients. The mechanism of methadone metabolism and disposition has been shown to involve cytochrome P450 (CYP450) and P-glycoprotein.

Construction of evolutionary tree models for nasopharyngeal carcinoma using comparative genomic hybridization data.

Nasopharyngeal carcinoma (NPC) is a malignancy associated with remarkable racial and geographic factors. The development and progression of NPC may involve the accumulation of multiple genetic alterations over a long time. For understanding the putative order of genetic alteration in NPC tumorigenesis, we used evolutionary tree models (branching and distance-based tree models) to analyze comparative genomic hybridization (CGH) data of previously published NPC cases (n = 103).
