Methamphetamine (METH), a commonly abused psychostimulant, has been shown to induce neuronal damage by causing reactive oxygen species (ROS) formation, apoptosis and autophagy. Taurine (2-aminoethanesulfonic acid) is involved in several physiological actions in the brain, including neuroprotection, osmoregulation and neurotransmission. In this study, we(More)
The mechanism of tamoxifen action in the treatment of breast cancer is believed to be via active metabolites that act as potent estrogen receptor antagonists. Attempts to identify relationships between active metabolite concentrations and clinical outcomes have produced mixed results. Since anti-estrogenic effects may be brought about not only by estrogen(More)
The peripheral conversion of testosterone to estradiol by aromatase is the primary source of endogenous estrogen in postmenopausal women. Studies indicating that placental aromatase is able to metabolize methadone to its primary metabolite, 2-ethylidene-1, 5-dimethyl-3, 3-diphenylpyrrolidin (EDDP), led us to test the hypothesis that methadone is able to act(More)
Aberrant expression of DJ-1 has been proven to be associated with tumorigenesis in many carcinomas. However, its role in pancreatic cancer is unknown. The aims of this study were to investigate whether the serum DJ-1 might be a potential biomarker for pancreatic cancer and to determine the biologic function of DJ-1 expression in gemcitabine-induced(More)
BACKGROUND We systematically reviewed and performed a meta-analysis of the available data regarding neoadjuvant chemo- and/or radiotherapy with special emphasis on tumor response/progression rates, toxicities, and clinical benefit, i.e. resection probabilities and survival estimates. METHODS AND FINDINGS Trials were identified by searching PUBMED,(More)
The biomarker identification of human esophageal cancer is critical for its early diagnosis and therapeutic approaches that will significantly improve patient survival. Specially, those that involves in progression of disease would be helpful to mechanism research. In the present study, we investigated the distinguishing metabolites in human esophageal(More)
Rectal cancer is one of the most prevalent tumor types. Understanding the metabolic profile of rectal cancer is important for developing therapeutic approaches and molecular diagnosis. Here, we report a metabonomics profiling of tissue samples on a large cohort of human rectal cancer subjects (n = 127) and normal controls (n = 43) using 1H nuclear magnetic(More)
Several approximate dynamic programming (ADP) algorithms have been developed and demonstrated for the model-free control of continuous and discrete dynamical systems. However, their applicability to hybrid systems that involve both discrete and continuous state and control variables has yet to be demonstrated in the literature. This paper presents an ADP(More)
This paper introduces the research progress related to the antioxidant activity of bamboo leaf flavonoid (EOB-f) and its pharmacological activity of heart and cerebral vessels. The paper studied what role EOB-f played in the diagnosis of heart and cerebral vessels, based on the in vitro, in vivo and animal model as well as the pharmacological research(More)
We propose and demonstrate a novel test structure to characterize the electrical properties of nano-scale metal–semiconductor contacts. The structure is in essence a two-port transmission line model (TLM) with contacts in the nanometer regime. Unlike the conventional TLM, two types of Kelvin measurements are possible. When performed on devices with(More)
