Activation of sulfite by metal-organic framework-derived cobalt nanoparticles for organic pollutants removal.

Sulfite (SO) activation is one of the most potential sulfate-radical-based advanced oxidation processes, and the catalysts with high efficiency and low-cost are greatly desired. In this study, the cobalt nanoparticles embedded in nitrogen-doped graphite layers (Co@NC), were used to activate SO for removal of Methyl Orange in aqueous solution. The Co@NC catalysts were synthesized via pyrolysis of Co-based metal-organic framework (Co-MOF), where CoO was firstly formed at 400℃ and then partially reduced to Co nanoparticles embedded in carbon layers at 800℃.

The lncRNA Promotes Hepatocellular Carcinoma Cell Cycle Progression by Regulating the HuR/CDK4 Axis.

Long noncoding RNAs (lncRNAs) represent promising therapeutic targets associated with hepatocellular carcinoma (HCC). lncRNA VPS9D1 antisense RNA 1 () regulates colon and prostate cancer, but its relevance in HCC remains to be clarified. Using microarray data from the NCBI Gene Expression Omnibus (GEO) database (GSE65485) and The Cancer Genome Atlas (TCGA) database, expression in HCC and normal liver tissue sample HCC were compared.

PKMYT1 Promotes Gastric Cancer Cell Proliferation and Apoptosis Resistance.

Background: Abnormal expression of protein kinase membrane associated tyrosine/threonine 1 (PKMYT1) is closely associated with multiple types of cancers. In the present study, we examined the roles of PKMYT1 in gastric cancer (GC) progression.

Methods: We examined the expression status of PKMYT1 in GC tissues and cell lines.

Multimodal therapy and twenty years of valid management of a patient with chronic hepatitis B in a less developed Western Region in China---case report and review of the literature.

Background: For patients with chronic hepatitis B and cirrhosis in less developed western regions in China, due to constraints of local economic conditions, the choice of treatment measures is often limited. However if patients recieved valid management and effective treatment, they were able to maintain their health and benign prognosis.

Case Presentation: This study narrates the long-term treatment and careful follow-up of a patient with chronic hepatitis B and cirrhosis in a less developed western region in China, and analyzes the prognosis of the disease and countermeasures.

Cobalt nanoparticles encapsulated in nitrogen-rich carbon nanotubes as efficient catalysts for organic pollutants degradation via sulfite activation.

The activation of sulfite by heterogeneous catalysts displays a great potential in the development of new sulfate radials based technologies for wastewater treatment. Herein, cobalt nanoparticles embedded in N-doped carbon nanotubes (Co@NC) were prepared by a simple pyrolysis method. Due to the synergistic effects of the cobalt nanoparticles and N-doped carbon nanotubes, the Co@NC catalyst intrinsically shows an outstanding efficiency, excellent reusability and high stability in the catalytic oxidation of methyl orange (MO) in the presence of sulfite and dioxygen.

4-(4-Pyrid-yl)pyridinium perchlorate methanol solvate.

In the cation of the title hydrated molecular salt, C(10)H(9)N(2) (+)·ClO(4) (-)·CH(3)OH, the dihedral angle formed by the pyridine rings is 28.82 (15)°. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯N hydrogen bonds and π-π stacking inter-actions, with centroid-to-centroid distances of 3.
