Effects of Ultrashort Wave Therapy on Inflammation and Macrophage Polarization after Acute Lung Injury in Rats.

Bioelectromagnetics 2021 Jun 15. Epub 2021 Jun 15.

Rehabilitation Medicine Center, The First Affiliated Hospital of University of South China, Hengyang, People's Republic of China.

Acute lung injury (ALI) features dysregulated pulmonary inflammation. Ultrashort waves (USWs) exert anti-inflammatory effects but no studies have evaluated their activity in ALI. Herein, we used an in vivo lipopolysaccharide (LPS)-induced ALI model to investigate whether the anti-inflammatory activity of USWs is mediated by altering the polarization of M1 to M2 macrophages.

Deeply Mining a Universe of Peptides Encoded by Long Noncoding RNAs.

Mol Cell Proteomics 2021 Jun 12:100109. Epub 2021 Jun 12.

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.

Visible-Light Photocatalytic Oxidation of DMSO for RAFT Polymerization.

Photochem Photobiol 2021 Jun 15. Epub 2021 Jun 15.

University of Maryland, Department of Chemistry and Biochemistry, College Park, MD, USA, 20942.

The solvent is an important, yet often forgotten part of a reaction mechanism. Many photochemical polymerizations are carried out using dimethyl sulfoxide (DMSO) as a way to promote the solubility of both the reactants and products, but its reactivity is rarely considered when initiation mechanisms are proposed. Herein, the oxidation of DMSO by an excited state quinone is used to form initiating radicals resulting in the polymerization of methacrylate monomers, and the polymerization can be controlled with the addition of a chain transfer agent.
