Accumulated evidence demonstrated that long non-coding RNAs (lncRNAs) play a pivotal role in tumorigenesis. However, it is still largely unknown how these lncRNAs were regulated by small ncRNAs, such as microRNAs (miRNAs), at the post-transcriptional level. We here use lncRNA HOTTIP an example to study miRNAs impact expression and its biological significance hepatocellular carcinoma (HCC). LncRNA vital oncogene HCC, one of deadliest cancers worldwide. In current study, we identified miR-192...
Copper nanostructures represent an important class of materials in CO2 electrocatalytic reduction (CO2ER) reactions, but deciphering their molecular structures, especially those with multiple and irregular organic–inorganic interfaces, remains a grand challenge.

Manipulating the interfacial/surface structure of ligand-stabilized atomically precise metal nanoclusters (NCs) is one central tasks in nanoscience because surface motifs are directly related to key properties nanomaterials. Although great progress has been made engineering gold and silver nanoclusters, parallel studies on lighter copper analogues hitherto remain unexplored. In this work, we report design, synthesis, a new class featuring virtually identical kernels but different motifs. The...

High-dose (HD) tigecycline is often required for severe multidrug-resistant gram-negative infections in liver failure patients, despite package recommendations to halve the dose those with impairment. This study evaluated efficacy and safety of different doses this population. A retrospective cohort 192 patients Child-Pugh grade C was divided into label-dose (LD), standard-dose (SD), HD groups. Primary secondary outcomes included microbial eradication, mortality, adverse effects. The SD...
Spherical nanoparticles as a classic delivery vehicle for anticancer drugs have been extensively investigated, but study on the shape of has received little attention until now.

This paper proposes a two-step method for phosphogypsum (PG) decomposition by circulating various atmospheres instead of single atmosphere. To achieve high concentration CaO in the final product, PG was decomposed reducing atmosphere with CO (99.99%) at rising temperature until mass loss changes stably first step reaction. For second-step reaction, changed from to an oxidizing one air constant temperature. With different temperatures, analysis thermogravimetric analyzer (TGA) and Factsage6.1...

Atomically precise copper nanoclusters have emerged as a promising class of catalysts for driving chemical reactions. However, the exploration nanocluster has been slow, likely due to their complex synthetic process, limited stability, and low activity under mild conditions.
