Eribulin Induction of Immunogenic Cell Death (ICD): Comparison With Other Cytotoxic Agents and Temporal Relationship of ICD Biomarkers.

Background/aim: Preclinical studies were undertaken to investigate whether eribulin's known cytotoxic antimitotic effects are characterized by immunogenic cell death (ICD) as assessed by three established ICD biomarkers: extracellular released ATP, released HMGB1 and cell surface calreticulin.

Materials And Methods: Using BT-549, Hs578T and MCF-7 breast cancer cell lines, antiproliferative IC's of eribulin, five other microtubule targeting agents (MTAs; ER-076349, vinblastine, vinorelbine, paclitaxel, docetaxel) and three DNA damaging agents (DDAs; doxorubicin, cisplatin, oxaliplatin) were determined.

Results: Treatment of cells with 10×IC concentrations of all drugs in serum-free media resulted in time-dependent induction of cytotoxicity over DMSO controls.

An in situ reactive zone approach using calcium peroxide for the remediation of benzene and chlorobenzene in groundwater: A field study.

There is a gap in understanding the different contributions of biodegradation and free radical oxidation using calcium peroxide (CaO) for the remediation of mixed contaminants of benzene and chlorobenzene in groundwater. In this study, the remedial efficiency and mechanisms of benzene and chlorobenzene co-contaminants using CaO were explored by an integrated approach of field study and laboratory validation. It was found that in the field demonstration program, the radius of influence for each injection point using Geoprobe direct-push was larger than the designed value of 0.

A CRISPR/Cas12a-based direct transverse relaxation time biosensor via hydrogel sol-gel transition for Salmonella detection.

This research developed a magnetic relaxation switching (MRS) biosensor based on hydrogel sol-gel transition and the CRISPR/Cas12a system (MRS-CRISPR) to detect Salmonella. Herein, the alkaline phosphatase (ALP) labeled with streptavidin was captured by the biotin-modified DNA on magnetic nanoparticles (MNPs) surface, which generated an acidic environment via enzymatic reaction to release Ca and induced the transformation of alginate sol to hydrogels. In contrast, Salmonella activated the trans-cleavage activity of the CRISPR/Cas12a system, interrupting the capture of ALP and the subsequent sol-gel transition.

Obesity-induced activation of NADPH oxidase 2 prolongs cardiac repolarization via inhibiting K+ currents.

Obesity is associated with abnormal repolarization manifested by QT interval prolongation, and oxidative stress is an important link between obesity and arrhythmias. However, the underlying electrophysiological and molecular mechanisms remain unclear. The aim of this study is to evaluate the role of obesity in potassium current in ventricular myocytes and the potential mechanism of NADPH oxidase 2 (Nox2).
