Previously, we reported the discovery of several dysregulated circRNAs including circPABPC1 (polyadenylate-binding protein 1) in human hepatocellular carcinoma (HCC), although their roles in HCC development remained unclear.

    1997-6-30 · Bioremediation is being used or proposed as a treatment option at many hydrocarbon-contaminated sites. One such site is a former bulk-fuel storage facility near Barrow, AK, where contamination persists after approximately 380 m3 of JP-5 was spilled in 1970. The soil at the site is primarily coarse sand with low organic carbon (<1%) and low moisture (1−3%) contents. We …

  • Effect of grassland degradation on soil quality and soil ...

    2020-11-11 · Effect of grassland degradation on soil quality index. Grassland degradation significantly influenced plant biomass (Table 1), with lower aboveground biomass observed in the degraded grassland (DG) than that in meadow steppe (MG) and the grassland from forest-steppe ecotone (TG), but the root biomass did not differ among three grassland types (Table 1).

    2021-3-30 · Microcystins (MCs) are extremely hazardous to the ecological environment and public health. How to control and remove MCs is an unsolved problem all over the world. Some microbes and their enzymes are thought to be effective in degrading MCs. Microcystinase can linearize microcystin-leucine-arginine (MC-LR) via a specific locus. However, linearized MC-LR is also very toxic and needs to be …

    2021-2-24 · Periodontitis is a common chronic inflammatory disease driven by the interaction between a dysbiotic oral microbiome and the dysregulated host immune-inflammatory response. Naturally derived nutraceuticals, such as resveratrol and its analogs, are potential adjunctive therapies in periodontal treatment due to their antimicrobial and anti-inflammatory properties.

    2020-11-2 · Carbon dot (CD) and palladium nanoparticle (Pd NP) composites are semiconducting materials having tremendous applications in catalysis with suitable band gaps. However, their combination with a suitable polymer matrix in sonophotocatalysis has not been explored. Herein, we have synthesized and characterized a new nanohybrid catalyst from a polyamide cross-linked CD-polymer …

  • China Land Policy Reform for Sustainable Economic

    Heat‐shock proteins (Hsps) protect proteins, membranes, and other cellular components during heat stress, and facilitate repair and degradation of denatured proteins following a stressful event (Parsell and Lindquist 1993; Wang et al. 2004).In spite of the ubiquitous nature of Hsps, and their central role in thermotolerance, there is substantial variation in the suite, magnitude, and ...
