Curcumin, a major component of the Curcuma species, is known to have antioxidant, anti-inflammatory properties and induce apoptosis of cancer cells, however, the precise molecular mechanisms of apoptosis in vitro are unclear. In this study, we showed that curcumin, a plant product containing the phenolic phytochemical, caused DNA damage and endoplasmic(More)
Overexpression of ribonucleotide reductase M2 (hRRM2) and p53-dependent RR small subunit (p53R2) has been correlated with tumor malignancy and progression in several types of cancer. The aim of this study was to determine the association of p53R2/hRRM2 expression with clinicopathological characteristics of stage I and II non-small cell lung cancer (NSCLC).(More)
There is good evidence that endotoxemia, sepsis, and septic shock are associated with the generation and release of reactive oxygen species (ROS) such as superoxide anion (O2), indicating that oxygen-derived free radicals play an important role in the pathogenesis of sepsis/shock. Studies on the application of free oxygen radical scavengers to limit the(More)
PURPOSE Inhibitors of antiapoptosis protein (IAP) have been implicated in the resistance to cisplatin. Therefore, verifying which pathway is involved in cIAP2 upregulation may be helpful in finding a feasible pathway inhibitor to increase the chemotherapeutic efficacy in human papillomavirus (HPV)-infected lung cancer. EXPERIMENTAL DESIGN Specific(More)
The pathogenesis of multiple organ dysfunction syndrome (MODS) in septic shock is complicated and not fully understood. Some studies show that an overproduction of nitric oxide (NO) leads to the refractory hypotension and multiple organ failure, while other studies suggest that free radicals, e.g. superoxide (O(2)(-)), contribute to the detrimental effect(More)
It is generally accepted that bacterial endotoxin (lipopolysaccharide, LPS) acts via endogenous mediators leading to endotoxicity. Among these endogenous mediators, tumor necrosis factor-alpha (TNF-alpha) seems to induce all characteristics for endotoxemia. Inhibition of TNF-(alpha production by cAMP-elevating agents has been well documented. Terbutaline(More)
BACKGROUND Our recent report indicated that MGMT hypermethylation is more common in squamous cell carcinomas (SCC) in males, and smokers than in adenocarcinomas (ADC) in females, and nonsmokers. More interestingly, MGMT hypermethylation in SCC and ADC was pronouncedly influenced by gender factor, not by smoking status. We questioned whether 17beta-estradiol(More)
BACKGROUND O(6)-methylguanine-DNA methyltransferase (MGMT) promoter methylation has been demonstrated to associate with the G:C-->A:T transition mutation in the p53 gene of lung tumors. The purpose of this study is to clarify whether MGMT promoter methylation is not only associated with the shift from the G:C-->A:T mutation in the p53 gene but also whether(More)
The purpose of this study was to develop a web-based short messaging service (SMS) system in the operating room (OR). At the same time, we integrated and analyzed the limits of SMS in the OR. A cross-sectional study with quantitative methods and convenience sampling was used to gather data in this study. In the SMS project, we approached the content of SMS(More)
BACKGROUND Inconsistency in the prevalence of infection by human papillomavirus (HPV) in lung cancer patients was found between different countries with racial and geographic variations. Our previous reports have indicated that a high-risk HPV 16/18 DNA was frequently detected in Chinese lung cancer patients living in Taichung, Taiwan (Cheng et al. Cancer(More)
