Controversy is an integral part of scientific research and is often a precursor to the truth. However, this lesson has been learned in a very hard way in the case of the structurefunction relationship of adenylate kinase (AK),' which catalyzes the interconversion between MgATP + AMP and MgADP + ADP. While this small kinase has been considered a " model(More)
We conducted a case-control study to assess the LIG4 and XRCC4 genes polymorphisms and development of glioma. A case-control study including 162 glioma cases and 324 controls was conducted in a Chinese population. Genotypes of rs10131 and rs1805388 in LIG4 and rs2075685 and rs1805377 in XRCC4 were conducted by polymerase chain reaction restriction fragment(More)
Studies on the relationship of HAP1 polymorphisms (−141 T > G; 1349 T > G) and lung cancer risk to date indicated controversial results. This study was devised to clarify whether the polymorphisms predispose to lung cancer. We searched Embase and PubMed up to March 2014 to identify relevant studies. Data from the eligible studies were independently(More)
, has been retracted by the authors request. The authors have recently obtained new results conflicting with those presented in the pubb lished article. Careful analysis showed that some published results were obtained using inappropriate methods and wrong statistical analysis. The authors apologize and ask readers to ignore the results published in this(More)
Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. Leptin is a pleiotropic hormone with antiapoptotic and proliferative roles involved in several systems. However, there is no known antiapoptotic mechanism of leptin in non-small cell lung cancer (NSCLC). So, we investigated the antiapoptotic mechanism of leptin in(More)
In order to investigate the biological mechanisms underlying the clinical efficacy of clozapine, 200 mg/day of clozapine was added to the drug regimens of 19 patients with chronic, anti-psychotic-resistant schizophrenia, and the plasma homovanillic acid (HVA), clozapine concentrations, anti-dopamine D2 and anti-serotonin 5-HT2 receptor activities were(More)
