An Inflammatory Response Related Gene Signature Associated with Survival Outcome and Gemcitabine Response in Patients with Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive tumors with an extremely low 5-year survival rate. Accumulating evidence has unveiled that inflammatory response promotes tumor progression, enhances angiogenesis, and causes local immunosuppression. Herein, we aim to develop an inflammatory related prognostic signature, and found it could be used to predict gemcitabine response in PDAC.

Comparing the efficacy of bag-valve mask, endotracheal intubation, and laryngeal mask airway for subjects with out-of-hospital cardiac arrest: an indirect meta-analysis.

Background: For subjects with out-of-hospital cardiac arrest (OHCA), bag-valve mask (BVM), endotracheal intubation (ETI), and laryngeal mask airway (LMA) are the most common methods of ventilatory support; however, the best choice remains controversial.

Methods: A comprehensive search of online databases was performed. A traditional meta-analysis was performed to determine the risk ratio of BVM LMA and ETI LMA.

Layer-by-layer nanoparticles co-loading gemcitabine and platinum (IV) prodrugs for synergistic combination therapy of lung cancer.

Purpose: Cisplatin plus gemcitabine (GEM) is a standard regimen for the first-line treatment of advanced non-small cell lung cancer. The aim of this study was to prepare biocompatible and biodegradable polymeric prodrugs and construct nanoparticles (NPs) with layer-by-layer (LbL) technique.

Methods: Platinum (Pt) (IV) complex with a carboxyl group was conjugated to the amino group of chitosan (CH), resulting in a CH-Pt conjugation with positive charge.

Development and validation of a liquid chromatography/tandem mass spectrometry assay for the simultaneous determination of dabigatran etexilate, intermediate metabolite and dabigatran in 50μL rat plasma and its application to pharmacokinetic study.

A simple, rapid and specific high performance liquid chromatography-electrospray ionization tandem mass spectrometry method was developed for simultaneous determination of dabigatran etexilate (BIBR 1048 MS), the intermediate metabolite (BIBR 1087 SE) and dabigatran (BIBR 953 ZW). In this method, a stacked protein precipitation with methanol was performed in Sirocco 96-well filtration plates to extract analytes using only 50μL plasma. The analysis was performed on an Ultimate TM XB-C18 (4.

Simultaneous determination of amlodipine and bisoprolol in rat plasma by a liquid chromatography/tandem mass spectrometry method and its application in pharmacokinetic study.

A sensitive, specific liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was established for the quantitative determination of amlodipine and bisoprolol, using clenbuterol as the internal standard (IS). The analytes and IS were isolated from 100μL plasma samples by a simple liquid-liquid extraction (LLE). Reverse-phase high performance liquid chromatography (RP-HPLC) separation was accomplished on a Diamonsil C(18) column (50mm×4.
