The Autophagosomes Containing Dengue Virus Proteins and Full-Length Genomic RNA Are Infectious.

Autophagic machinery is involved in selective and non-selective recruitment as well as degradation or exocytosis of cargoes, including pathogens. Dengue virus (DENV) infectioninduces autophagy that enhances virus replication and vesicle release to evade immune systemsurveillance. This study reveals that DENV2 induces autophagy in lung and liver cancer cells andshowed that DENV2 capsid, envelope, NS1, NS3, NS4B and host cell proinflammatory high mobilitygroup box 1 (HMGB1) proteins associated with autophagosomes which were purified by gradientcentrifugation.

Preoperative Evaluation of V-Y Flap Design Based on Computer-Aided Analysis.

V-Y flap is widely used in plastic surgery as an important technique for reconstructing deformities and improving appearance. In this paper, a geometrical parameter model and finite element analysis were used to study the rationale of the proposed V-Y flap design and the preoperative evaluation of the V-Y flap design. First, a geometric parameter model of the V-Y flap was established to analyze the five key geometric relationships affecting the flap structure and obtain a reasonable plan for the V-Y flap design through the crossing constraint relationship.

An optimized method for neurotransmitters and their metabolites analysis in mouse hypothalamus by high performance liquid chromatography-Q Exactive hybrid quadrupole-orbitrap high-resolution accurate mass spectrometry.

Neurotransmitters (NTs) and their metabolites are known to play an essential role in maintaining various physiological functions in nervous system. However, there are many difficulties in the detection of NTs together with their metabolites in biological samples. A new method for NTs and their metabolites detection by high performance liquid chromatography coupled with Q Exactive hybrid quadruple-orbitrap high-resolution accurate mass spectrometry (HPLC-HRMS) was established in this paper.

Design, synthesis and biological evaluation of novel arylpiperazine derivatives on human prostate cancer cell lines.

A series of novel arylpiperazine derivatives was synthesized. The in vitro cytotoxic activities of all synthesized compounds against three human prostate cancer cell lines (PC-3, LNCaP, and DU145) were evaluated by a CCK-8 assay. Compounds 10, 24 and 29 exhibited strong cytotoxic activities against LNCaP cells (IC50 <3μM).

An optimized method for corticosterone analysis in mouse plasma by ultra-performance liquid chromatography-full-scan high-resolution accurate mass spectrometry.

A simple method based on liquid chromatography-full-scan high-resolution accurate mass spectrometry (LC-HRMS) using a quadrupole time-of-flight (TOF) mass spectrometry was developed and optimized for corticosterone quantification in mouse plasma. Mouse plasma (100 μL) was extracted with methyl tert-butyl ether using prednisone as internal standard. Separation was performed on a short C18 column using a methanol-water gradient.

The Wnt5a/Ror2 noncanonical signaling pathway inhibits canonical Wnt signaling in K562 cells.

Wnt5a has been shown to be involved in cancer progression in a variety of tumor types, and regulates multiple intracellular signaling cascades; it is a representative ligand that activates a noncanonical Wnt signaling pathway. The mechanism governing how Wnt5a determines the specificity of these pathways and the relationship with tumorigenesis is still unknown. In this study, we aimed to clarify the tumor suppressor role of Wnt5a in leukemogenesis.

The C-terminal aqueous-exposed domain of the 45 kDa subunit of the particulate methane monooxygenase in Methylococcus capsulatus (Bath) is a Cu(I) sponge.

The crystal structure of the particulate methane monooxygenase (pMMO) from Methylococcus capsulatus (Bath) has been reported recently [Lieberman, R. L., and Rosenzweig, A.
