BACKGROUND: Anticoagulant rodenticides have been widely used in rodent control in China for over 30 years and resistant Norway rats have been reported. Mutations in the vitamin K epoxide reductase complex, subunit 1 (Vkorc1) gene can cause anticoagulant resistance in rodents. In this study, we analyzed the Vkorc1 polymorphisms of 681 Norway rats collected in Zhanjiang and Harbin City in China from 2008 to 2015 and evaluated the warfarin resistance frequency. RESULTS: Analysis revealed 4 mutations including 3 not previously reported...

Xingang Zhang, Lun An, Yu-Lan Xiao, Shu Zhang
Although iron-catalyzed cross-coupling of Grignard reagents with alkyl halides has been well established, the adoption of the reaction for fluoroalkylations has not been reported because traditional catalytic systems often lead to defluorination reactions. Here, we describe our investigation of an iron-catalyzed cross-coupling between arylmagnesium and difluoroalkyl bromides with steric modified N,N,N',N'-tetramethyl-ethane-1,2-diamine (TMEDA) (L4) as a ligand. The use of a bulky diamine ligand (L4), in which a butylene is substituted at one carbon atom of ethylene backbone in TMEDA, enables the iron-catalyzed difluoroalkylation under mild reaction conditions with a wide range of difluoroalkyl bromides including vulnerable bromodifluoromethane, thus providing a general and cost-efficient route for application in medicinal chemistry...

Temporal and spatial variations in landfill gas generations and emissions have been observed and reported by others. Real-time gas data between 2008 and 2014 from a municipal landfill located in a cold, semi-arid climate were consolidated to fit a linear-interpolated form of LandGEM. Seasonal variations in gas collection were observed in the landfill. LandGEM's default decay rate k was not applicable for this Canadian landfill due to significant overestimation (32.2% error). Optimal seasonal k and Lo collection parameters had 8...

2-Phenylethanol (2-PE) is a kind of advanced aromatic alcohol with rose fragrance, which is wildly used for the deployment of flavors and fragrances. Microbial transformation is the most feasible method for the production of natural 2-PE. But a bottleneck problem is the toxicity of 2-PE on the cells. The molecular mechanisms of the toxic effect of 2-PE to Saccharomyces cerevisiae are not well studied. In this study, we analyzed the transcriptomes of S. cerevisiae in the media with and without 2-PE, respectively, using Illumina RNA-Seq technology...

The budgerigar ( Melopsittacus undulatus ) is one of the most widely studied parrot species, serving as an excellent animal model for behavior and neuroscience research. Until recently, it was unknown how sexual differences in the behavior, physiology, and development of organisms are regulated by differential gene expression. MicroRNAs (miRNAs) are endogenous short non-coding RNA molecules that can post-transcriptionally regulate gene expression and play a critical role in gonadal differentiation as well as early development of animals...

PURPOSE: B-cell lymphoma-2 (BCL-2), an anti-apoptotic protein often dysregulated in B-cell lymphomas, promotes cell survival and provides protection from stress. A recent Phase I first-in-human study of the BCL-2 inhibitor venetoclax in non-Hodgkin lymphoma showed an overall response rate of 44%. These promising clinical results prompted our examination of the biological effects and mechanism of action underlying venetoclax activity in aggressive B-cell lymphoma, including mantle cell lymphoma (MCL) and diffuse large B cell lymphoma (DLBCL)...

Tumor angiogenesis is mainly regulated by vascular endothelial growth factor (VEGF), produced by cancer cells. It is active on the endothelium via VEGF receptor 2 (VEGFR-2). G-quadruplexes are DNA secondary structures formed by guanine-rich sequences, for example, within gene promoters where they may contribute to transcriptional activity. The proximal promoter of vegfr-2 contains a G-quadruplex, which has been suggested to interact with small molecules that inhibit VEGFR-2 expression and thereby tumor angiogenesis...

BACKGROUND: Metformin (Met) is a widely available diabetic drug and shows suppressed effects on renal cell carcinoma (RCC) metabolism and proliferation. Laboratory studies in RCC suggested that metformin has remarkable antitumor activities and seems to be a potential antitumor drug. But the facts that metformin may be not effective in reducing the risk of RCC in cancer clinical trials made it difficult to determine the benefits of metformin in RCC prevention and treatment. The mechanisms underlying the different conclusions between laboratory experiments and clinical analysis remains unclear...

Immunotherapy has become a promising cancer therapy, but only works for a subset of cancer patients. Immunogenic photodynamic therapy (PDT) can prime cancer immunotherapy to increase the response rates, but its efficacy is severely limited by tumor hypoxia. Here we report a nanoscale metal-organic framework, Fe-TBP, as a novel nanophotosensitizer to overcome tumor hypoxia and sensitize effective PDT, priming non-inflamed tumors for cancer immunotherapy. Fe-TBP was built from iron clusters and porphyrin ligands and sensitized PDT under both normoxic and hypoxic conditions...
