Anti-adipogenesis and anti-obesity potential of alliin mediated by modulating glycolipid metabolism via activating PPARγ signaling.

Garlic exhibits hypolipidemic, hypoglycemic, and cardiovascular benefits. The inconsistent results of garlic preparations on adipogenesis have caused more confusion in the public and academia. The compounds responsible for the anti-adipogenesis effect of garlic remain unknown.

Metastatic clear cell sarcoma of the pancreas: A rare case report.

Background: Clear cell sarcoma (CCS) is a rare soft-tissue sarcoma. The most common metastatic sites for CCS are the lungs, bones and brain. CCS is highly invasive and mainly metastasizes to the lung, followed by the bone and brain; however, pancreatic metastasis is relatively rare.

IL-17A/p38 Signaling Pathway Induces Alveolar Epithelial Cell Pyroptosis and Hyperpermeability in Sepsis-Induced Acute Lung Injury by Activating NLRP3 Inflammasome.

Sepsis is a syndrome with poor prognosis. Nucleotide-binding domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome and T helper 17 (Th17) cells are involved in the pathogenesis of inflammatory diseases. This study aims to explore their roles and underlying mechanisms in sepsis.

The clinical effect evaluation of multidisciplinary collaborative team combined with palliative care model in patients with terminal cancer: a randomised controlled study.

Objective: To evaluate the clinical effect of a multidisciplinary collaboration team combined with a palliative care model in patients with terminal cancer.

Multi-Layered Branched Surface Fluorination on PVDF Membrane for Anti-Scaling Membrane Distillation.

Membrane distillation (MD) has emerged as a promising technology for hypersaline wastewater treatment. However, membrane scaling is still a critical issue for common hydrophobic MD membranes. Herein, we report a multi-layered surface modification strategy on the commercial polyvinylidene fluoride (PVDF) membrane via plasma treatment and surface fluorination cycles.

Identification of the major photodegradant in metronidazole by LC-PDA-MS and its reveal in compendial methods.

Metronidazole in aqueous solution is sensitive to light and UV irradiation, leading to the formation of N-(2-hydroxyethyl)-5-methyl-l,2,4-oxadiazole-3-carboxamide. This is revealed here by liquid chromatography with tandem photo diode array detection and mass spectrometry (LC-PDA-MS) and further verified by comparison with the corresponding reference substance and proton nuclear magnetic resonance (H-NMR). However, in current compendial tests for related substances/organic impurities of metronidazole, the above photolytic degradant could not be detected.

CircRNA_0084927 promotes colorectal cancer progression by regulating miRNA-20b-3p/glutathione S-transferase mu 5 axis.

Background: Colorectal cancer (CRC) is the third most common cancer and the second most common cause of cancer-related death worldwide. The 5-year survival rate of patients with early-stage CRC could reach 90%, but it is very low in patients with advanced-stage CRC. Recent studies have shown that circular RNAs play important roles in regulating the migration and invasion of CRC cells.

Antimicrobial Secondary Metabolites from the Seawater-Derived Fungus SW9.

Marine-derived fungi are considered to be valuable producers of bioactive secondary metabolites used as lead compounds with medicinal importance.

Their structures were determined by extensive 1D/2D NMR and mass spectrometric data, and the absolute configurations of and were assigned by the analysis of ECD spectra aided by quantum chemical computations.

The 24-Hour Intensivists Staffing Model Improves the Outcome for Nighttime Admitted Patients: A Matched Historical Control Study.

Introduction: We previously showed that a "10-hour daytime on-site" and "nighttime (NT) on-call" staffing strategy was associated with higher mortality for intensive care unit (ICU) patients admitted during NT than it was for patients admitted during office hours (OH). In here, we evaluated the clinical effects of a 24-hour intensivist staffing model.

Methods: We formed an intervention group of 3034 consecutive ICU patients hospitalized from January 2013 to December 2015, and a control group of 2891 patients from our previous study (2009-2011).

Resemblance in Corrosion Behavior of Selective Laser Melted and Traditional Monolithic β Ti-24Nb-4Zr-8Sn Alloy.

Distinct corrosion behavior was reported in multiphased titanium alloys prepared by additive manufacturing and by traditional technologies because of different phase constituents formed during processing. An open question is therefore raised: is there always different corrosion behavior of materials prepared by different methods? This work reports resemble corrosion behavior of selective laser melted and wrought single β-phase Ti-24Nb-4Zr-8Sn (Ti2448) in both NaCl solution and Hank's solution. The electrochemical measurements showed that both samples have close calculated polarization resistance and corrosion potential in NaCl solution, i.

Compelling Rejuvenated Catalytic Performance in Metallic Glasses.

Metallic glasses (MGs) with the metastable nature and random atomic packing structure have attracted large attention in the catalytic family due to their superior catalytic performance. In contrast, their crystalline counterparts are restricted by the highly ordered packing structure, fewer surface active sites, and crystallographic defects for catalytic activity. The uncertainty of the different catalytic mechanisms and the intrinsic characteristics correlated to MGs and their crystalline counterparts become a major impediment to promote their catalytic efficiencies and widespread applications.

Non-invasive ventilation in acute respiratory failure: a meta-analysis.

Non-invasive positive-pressure ventilation (NPPV) has assumed an important role in the management of respiratory failure because it provides ventilatory support without the need for an invasive airway. However, its effectiveness remains unclear. We performed this meta-analysis to investigate the utility of NPPV intervention in patients with acute respiratory failure (ARF).

[Screening potential DNA barcode regions of genus Papaver].

DNA barcoding is an effective technique in species identification. To determine the candidate sequences which can be used as DNA barcode to identify in Papaver genus, five potential sequences (ITS, matK, psbA-trnH, rbcL, trnL-trnF) were screened. 69 sequences were downloaded from Genbank, including 21 ITS sequences, 10 matK sequences, 8 psbA-trnH sequences, 14 rbcL sequences and 16 trnL-trnF sequences.

Synthesis and evaluation of trehalose-based compounds as novel inhibitors of cancer cell migration and invasion.

As a continuous research for the discovery of trehalose-based anti-invasive agents, we developed a convenient synthetic approach for the preparation of 6,6'-dideoxy-6,6'-bis(acylamino)-α,α-D-trehaloses. A series of trehalose-based amides were prepared through the trityl protection of the two primary hydroxyls of α,α-D-trehalose, benzoylation, the removal of the trityl protective group, mesylation, azidation, catalytic hydrogenation in the presence of hydrochloride, coupling reaction with a variety of acids, and subsequent debenzoylation and deacetylation in some cases. Compound 8b, 6,6'-dideoxy-6,6'-bis(2-hydroxybenzamide)-α,α-D-trehalose, was just as potent as the natural brartemicin against the invasion of murine colon 26-L5 cells.

To discuss the pathogenesis of Alzheimer's disease (AD), we summarized the mechanisms of treating AD animal models by acupuncture from literatures in recent years as follows. Senile dementia rats' cognitive capabilities and memory could be improved by reduction of beta-amyloid protein, attenuation of excessive phosphorylation of tau protein, regulation of center neurotransmitter dysmetabolism, oxidation of anti-free radicals, reduction of neuron apoptosis in the cortex and the hippocampus, inhibition of glial cells' differentiation, adjustment of G protein signaling transduction, and improvement of the mitochondrial dysfunction, thus providing experimental evidence for treating AD by acupuncture.
