Decorating Biaxially Oriented PVDF Nanocomposites with Ultralow Contents of Functionalized BNNSs for Excellent Energy Storage.

Poly(vinylidene fluoride) (PVDF) polymers are considered as promising high energy density capacitor dielectrics because of their high dielectric constants and melt processability. However, their industrialization and practicalization suffer from low breakdown strengths and high leakage conduction losses. Hence, it is of great necessity to develop dielectrics with a high energy storage capability.

Objectives: The incidence of peripheral arterial disease (PAD) in China is increasing. We aim to conduct a comprehensive analysis of the burden of PAD.

Methods: We collected information from 1990 to 2019 in the Global Burden of Disease (GBD 2019) study.

Inhibiting intracellular CD28 in cancer cells enhances antitumor immunity and overcomes anti-PD-1 resistance via targeting PD-L1.

Deciphering mechanisms for cancer immune escape may provide targets for improving immunotherapy efficacy. By in vivo genome-wide CRISPR loss-of-function screening in a mouse model of triple negative breast cancer (TNBC), we uncovered a non-classical function of Cd28 in cancer cells to promote immune escape. Knocking out Cd28 in cancer cells increased infiltration of type I conventional DC (cDC1) and activated tumor-specific CD8 T cells, and pharmaceutical inducible knockdown of Cd28 inhibited pre-established tumor growth and overcame anti-PD-1 resistance in vivo.

Fetal hepatocytes protect the HSPC genome via fetuin-A.

The maintenance of genomic integrity in rapidly proliferating cells is a substantial challenge during embryonic development. Although numerous cell-intrinsic mechanisms have been revealed, little is known about genome-protective effects and influences of developmental tissue microenvironments on tissue-forming cells. Here we show that fetal liver hepatocytes provide protection to haematopoietic stem and progenitor cell (HSPC) genomes.

[Pharmacovigilance guidelines for clinical application of traditional Chinese medicine injections].

In 2019, the newly revised Drug Administration Law of the People's Republic of China was issued and implemented,clearly proposing that China should establish a pharmacovigilance system. As a new traditional Chinese medicine(TCM) dosage form created in China, TCM injections have been widely used in clinic, and its pharmacovigilance has attracted much attention. In response to this situation, the project team convened a group of clinical, pharmaceutical and evidence-based medicine experts from all over the country to form an expert group, which formulated the Pharmacovigilance guidelines for clinical application of traditional Chinese medicine injections in strict accordance with the requirements of the group standards of the Chinese Association of Chinese Medicine.

Complete mitochondrial genome and phylogenetic analysis of Dollfustrema vaneyi (Trematoda: Bucephalidae).

Background: The Bucephalidae is a large family of digenean trematodes but most previous analyses of its phylogenetic position have relied on a single mitochondrial gene or morphological features. Mitochondrial genomes (mitogenomes) remain unavailable for the entire family. To address this, we sequenced the complete mitogenome of Dollfustrema vaneyi and analyzed the phylogenetic relationships with other trematodes.

Popliteal Artery Entrapment Syndrome: Updates for Evaluation, Diagnosis, and Treatment.

Popliteal artery entrapment syndrome remains difficult to diagnose. Meanwhile, our limited knowledge and understanding make treatment decisions complex. The list of differential diagnoses for exertional leg pain is broad.

Entropy-Driven Catalytic G-Quadruple Cycle Amplification Integrated with Ligases for Label-Free Detection of Single Nucleotide Polymorphisms.

G-Quadruplex/thioflavin (G4/THT) has become a very promising label-free fluorescent luminescent element for nucleic acid detection due to its good programmability and compatibility. However, the weak fluorescence efficiency of single-molecule G4/THT limits its potential applications. Here, we developed an entropy-driven catalytic (EDC) G4 (EDC-G4) cycle amplification technology as a universal label-free signal amplification and output system by properly programming classical EDC and G4 backbone sequences, preintegrated ligase chain reaction (LCR) for label-free sensitive detection of single nucleotide polymorphisms (SNPs).

Lewis-Acid-Promoted Visible-Light-Mediated C(sp)-H Bond Functionalization of Arylvinylpyridines via Diradical Hydrogen Atom Transfer.

A visible-light-induced intramolecular diradical-mediated hydrogen atom transfer (DHAT) of primary, secondary, and tertiary C(sp)-H bonds and subsequent cyclization is described. This transformation is enabled by triplet energy transfer upon Lewis acid coordination to alkyl-substituted arylvinylpyridines and gives access to a variety of benzocyclobutenes (>40 examples, 32-96% yield). Notably, tri- and tetrasubstituted olefins with tertiary C(sp)-H bonds effectively delivered sterically hindered products with adjacent all-carbon quaternary centers.

Simultaneous quantification of baloxavir marboxil and its active metabolite in human plasma using UHPLC-MS/MS: Application to a human pharmacokinetic study with different anticoagulants.

Baloxavir marboxil (BXM) is a cap-dependent nucleic acid endonuclease inhibitor, which exerts its antiviral effects after being metabolized to its active form baloxavir acid (BXA). Ethylenediamine tetra-acetic acid (EDTA) and heparin are the two most used anticoagulants in clinical blood sample collection to estimate drug levels in plasma. However, compared to heparin plasma, there is a lack of clinical pharmacokinetic data of BXA using EDTA anticoagulant tubes for blood collection.
