Engineering Electronic and Morphological Structure of Metal-Organic-Framework-Derived Iron-Doped NiP/NC Hollow Polyhedrons for Enhanced Oxygen Evolution.

The rational design of an oxygen electrocatalyst with low cost and high activity is greatly desired for realization of the practical water-splitting industry. Herein, we put forward a rational method to construct nonprecious-metal catalysts with high activity by designing the microstructure and modulating the electronic state. Iron (Fe)-doped NiP hollow polyhedrons decorated with nitrogen-doped carbon (Fe-NiP/NC HPs) are prepared by a sequential metal-organic-framework-templated strategy.

Replacing Oxygen Evolution with Hydrazine Borane Oxidation for Energy-Saving Electrochemical Hydrogen Production.

Electrochemical water splitting is a green strategy for hydrogen (H) production but is severely hindered by the sluggish anodic oxygen evolution reaction (OER). Therefore, replacing the sluggish anodic OER with more favorable oxidation reactions is an energy-saving approach for hydrogen production. Hydrazine borane (HB, NHBH) is considered a potential hydrogen storage material due to its easy preparation, nontoxicity, and high chemical stability.

Particle size optimization of metal-organic frameworks for superior capacitive deionization in oxygenated saline water.

Pyrolysis-free metal-organic frameworks (MOFs) with optimized particle sizes were used as capacitive deionization (CDI) materials in oxygenated saline water. Upon decreasing the particle size of the MOFs, excellent cycling stability and higher CDI performance were achieved. This was possibly due to the improvement in charge transfer and electrolyte permeation, uncovering the significance of particle size control in improving CDI performance.

Lactate regulators contribute to tumor microenvironment and predict prognosis in lung adenocarcinoma.

Background: Lactic acid, as a product of glycolysis, increases tumor cell migration and the invasion of tumor cells in the tumor microenvironment. Besides this, lactic acid promotes the expression of programmed death-1 expression (PD-1) in regulatory T cells, which could cause the failure of PD-1 blockade therapy. However, the implications of lactic acid in the tumor microenvironment of lung adenocarcinoma (LUAD) remain largely unclear.

Ultrasensitive and Selective Detection of Glutathione by Ammonium Carbamate-Gold Platinum Nanoparticles-Based Electrochemical Sensor.

Determining the concentration of glutathione is crucial for developing workable medical diagnostic strategies. In this paper, we developed an electrochemical sensor by electrodepositing amino-based reactive groups and gold-platinum nanomaterials on the surface of glassy carbon electrode successively. The sensor was characterized by cyclic voltammetry (CV), field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), and electrochemical impedance spectra (EIS).

Ligustilide counteracts carcinogenesis and hepatocellular carcinoma cell-evoked macrophage M2 polarization by regulating yes-associated protein-mediated interleukin-6 secretion.

Cross-communication between cancer cells and macrophages within the tumor microenvironment fulfills the critical roles in the progression of cancers, including hepatocellular carcinoma (HCC). Ligustilide exerts anti-inflammation, anti-injury, and anti-tumor pleiotropic pharmacological functions. Nevertheless, its roles in HCC cells and tumor microenvironment remain elusive.

LncRNA GAS5-mediated miR-1323 promotes tumor progression by targeting TP53INP1 in hepatocellular carcinoma.

MiR-1323 was identified in 2006. Until now, the roles and mechanisms of miR-1323 in the progression of cancers including hepatocellular carcinoma (HCC) remain unknown. The aim of this study was to investigate the expressions, roles and mechanisms of miR-1323 in HCC development.

Erratum: Downregulation of ubiquitin-specific peptidase 39 suppresses the proliferation and induces the apoptosis of human colorectal cancer cells.

[This corrects the article DOI: 10.3892/ol.2018.

Downregulation of ubiquitin-specific peptidase 39 suppresses the proliferation and induces the apoptosis of human colorectal cancer cells.

Ubiquitin-specific peptidase 39 (USP39) has been reported to participate in the mitotic spindle checkpoint and the process of cytokinesis. and has been identified as a therapeutic target for various types of cancer. However, the effect of USP39 in colorectal cancer (CRC) has not been investigated.

Copious Irrigation Versus Suction Alone During Laparoscopic Appendectomy for Complicated Appendicitis in Adults.

Objective: The objective of this study was to determine whether copious irrigation of peritoneal cavity during laparoscopic appendectomy for complicated appendicitis effectively reduces the incidence of postoperative complications and improves the postoperative recovery in adults compared with suction alone.

Methods: In this prospective randomized trial, adult patients with complicated appendicitis were randomized to "irrigation and suction"(IS) group or "suction only"(SO) group. All surgery was performed with a standardized 3-port laparoscopic approach.

HMGB1 knockdown effectively inhibits the progression of rectal cancer by suppressing HMGB1 expression and promoting apoptosis of rectal cancer cells.

Rectal cancer is a malignant gastrointestinal tumor, which is associated with high morbidity and mortality. High‑mobility group protein 1 (HMGB1) is widely present in the nucleus of eukaryotic cells, and is highly conserved between humans and rodents. Recently, HMGB1 has been reported to be involved in the progression and metastasis of human cancer; however, its role in the development and metastasis of human rectal cancer remains unclear.
