Highly efficient nano-Fe/Cu bimetal-loaded mesoporous silica Fe/Cu-MCM-41 for the removal of Cr(VI): Kinetics, mechanism and performance.

J Hazard Mater 2021 Jun 8;418:126344. Epub 2021 Jun 8.

Shaanxi provincial Center for Disease Control and Prevention, Xian 710054, China. Electronic address:

Zero valent iron (Fe) can reduce Cr(VI) in water, where Fe and Fe(Ⅱ) are possible electron donors, but passivation and aggregation easily occur to Fe. To improve the performance of Fe, a new hybridization strategy of Fe/Cu bimetal and silica-based mesoporous molecular sieve MCM-41 for the removal of Cr(VI) from water has been proposed. The results show that the two-dimensional mesoporous structure of MCM-41 can provide skeleton support for Fe, improve the mass transfer rate, and overcome the aggregation bottleneck of Fe. Read More

Tumor progress intercept by intervening in Caveolin-1 related intercellular communication via ROS-sensitive c-Myc targeting therapy.

Biomaterials 2021 Jun 7;275:120958. Epub 2021 Jun 7.

College of Pharmaceutical Science, Zhejiang University, Hangzhou, 310058, China. Electronic address:

Tumor-associated macrophages (TAMs) in the tumor microenvironment (TME) play an important role in the development of tumors by secreting a variety of cytokines or directly communicating with tumor cells, making TAMs-targeted therapeutic strategies very attractive. It has been reported that oncogene c-Myc is related to every aspect of the oncogenic process of tumor cells and the alternative activation of macrophages. Hence, we constructed a glycolipid nanocarrier containing ROS-responsive peroxalate linkages (CSOPOSA) for ROS-triggered release of drugs and further modified it with Ex 26 (Ex 26-CSOPOSA), a selective sphingosine 1-phosphate receptor 1 (S1PR1) antagonist, to achieve the dual-targeted delivery of the c-Myc inhibitor JQ1 via S1PR1, which is overexpressed on both tumor cells and TAMs, thereby inducing apoptosis of tumor cells, and blocking M2 polarization of macrophages.

Groundwater bacterial communities evolve over time in response to recharge.

Water Res 2021 May 26;201:117290. Epub 2021 May 26.

Aquatic Geomicrobiology, Institute of Biodiversity, Friedrich Schiller University Jena, Germany; German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, Germany. Electronic address:

Time series analyses are a crucial tool for uncovering the patterns and processes shaping microbial communities and their functions, especially in aquatic ecosystems. Subsurface aquatic environments are perceived to be more stable than surface oceans and lakes, due to the lack of sunlight, the absence of photosysnthetically-driven primary production, low temperature variations, and oligotrophic conditions. However, periodic groundwater recharge should affect the structure and succession of groundwater microbiomes. Read More

Laboratory of Protein and Peptide Pharmaceuticals & Laboratory of Proteomics, institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China; University of Chinese Academy of Sciences, Beijing 100049, China. Electronic address:

Many small open reading frames (smORFs) embedded in lncRNA transcripts have been shown to encode biologically functional polypeptides (smORFs-encoded polypeptides, SEPs) in different organisms. Despite significant advances in genomics, bioinformatics and proteomics that largely enabled the discovery of novel SEPs, their identification across different biological samples is still hampered by their poor predictability, diminutive size and low relative abundance. Here, we take advantage of NONCODE, a repository containing the most complete collection and annotation of lncRNA transcripts from different species, to build a novel database that attempts to maximize a collection of SEPs from human and mouse lncRNA transcripts.
