[Effects of propiconazole on physiological and biochemical properties of Panax notoginseng and dietary risk assessment].

To study the residue and dietary risk of propiconazole in Panax notoginseng and the effects on physiological and bioche-mical properties of P. notoginseng, we conducted foliar spraying of propiconazole on P. notoginseng in pot experiments.

Rapid determination and dietary intake risk assessment of 249 pesticide residues in Panax notoginseng.

UPLC-MS/MS and GC-MS/MS were used to establish a method to simultaneously determine various pesticide residues in Panax notoginseng. Results showed that the limits of detection of 249 pesticides were all 5-10 μg/kg. The detection rate of pesticides in 121 P.

Mechanistic Insight into the Chemiluminescent Decomposition of Dioxetanone and the Chemiluminescent, Fluorescent Properties of the Light Emitter of Bioluminescence.

bioluminescence has been increasingly used in bioimaging, bioanalysis, and biomedicine, due to high quantum yield and high signal-to-noise ratio. However, there is still no consensus regarding different aspects of the chemiluminescent mechanism of this system, which impairs the development of new applications. Herein, we have used a theoretical DFT and TD-DFT approach to (i) determine the identity of the dioxetanone species responsible for efficient chemiexcitation and (ii) identify the bioluminescent emitter and determine if light-emission occurs from the fluorescent or chemiluminescent state.

Study of miR-143 expression in stomach cancer.

The present study was planned to investigate miR-143 expression during stomach cancer. The study explored the relationship between miR-143 expression and clinicopathological characteristics including proliferation, migration and apoptosis of stomach cancer cells. Sixty-three samples from each of stomach cancer tissue and surrounding tissue were obtained.

Association of mRNA expression level of IP-10 in peripheral blood mononuclear cells with HBV-associated acute-on-chronic liver failure and its prognosis.

HBV-associated acute-on-chronic liver failure is prevalent in mainland China. The prognosis of HBV-ACLF is poor. The mortality of HBV-ACLF is approximately 80%.

Vitamin D deficiency and the risk of tuberculosis: a meta-analysis.

Background And Aim: To conduct meta-analyses of all published studies on various aspects of association between vitamin D and tuberculosis (TB).

Methods: PubMed and Web of Knowledge were searched for all properly controlled studies on vitamin D and TB. Pooled odds ratio, mean difference or standardized mean difference, and its corresponding 95% confidence interval were calculated with the Cochrane Review Manager 5.

A Computational Investigation of the Equilibrium Constants for the Fluorescent and Chemiluminescent States of Coelenteramide.

In spite of recent advances in understanding the mechanism of coelenterate bioluminescence, there is no consensus about which coelenteramide specie and/or state are the light emitter. In this study, a systematic investigation of the geometries and spectra of all possible light emitters has been performed at the TD ωB97XD/6-31+G(d) level of theory, including various fluorescent and chemiluminescent states in vacuum, in a hydrophobic environment and in aqueous solution. To deduce the most probable form of the fluorescent and chemiluminescent coelenteramide emitter, the equilibrium constants for the fluorescent and chemiluminescent states connecting the various species have been calculated.

Role of ERCC1 variants in response to chemotherapy and clinical outcome of advanced non-small cell lung cancer.

Excision repair cross-complementation group 1 (ERCC1) and xeroderma pigmentosum-F (XPF) in the nucleotide excision repair pathway have been effectively repairing DNA damage induced by chemotherapeutic agents. We conducted a cohort study to assess the associations of ERCC1 and XPF polymorphisms with response to platinum-based chemotherapy and clinical outcome of non-small-cell lung cancer (NSCLC). One hundred eighty-seven NSCLC cases treated with platinum-based chemotherapy were prospectively analyzed.

Correlation of -31G/C polymorphisms of survivin promoter to tumorigenesis of gastric carcinoma.

Background & Objective: Survivin, a bifunctional protein that regulates cell division and suppresses apoptosis, may play an important role in tumorigenesis. This study was to determine the correlations of survivin gene 31-GC polymorphisms to the occurrence of gastric carcinoma and survivin mRNA expression.

Methods: The -31G/C single nucleotide polymorphism (SNP) of survivin promoter in peripheral blood samples from 96 gastric carcinoma patients and 67 healthy subjects was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and gene sequencing.
