[Preparation of Iron-modified Biochar and Its Application in Arsenic Contaminated Soil Remediation].

Biochar has a range of advantages including large porosity, high specific surface area, and strong adsorption capacity. It has been widely used in environmental pollution remediation, soil improvement, and carbon sequestration and emission reduction. Arsenic (As) is a highly toxic pollutant widely distributed throughout the soil.

Circular RNA circ_0000423 promotes gastric cancer cell proliferation, migration and invasion via the microR-582-3p/Disheveled-Axin domain containing 1 axis.

For humans, gastric cancer (GC) is a common malignancy. Multiple circular RNAs (circRNAs) have been confirmed to be important cancer-promoting or tumor-suppressive factors. The present study discusses the roles and mechanisms of circ_0000423 in GC development.

[Application of numerical taxonomy in study of Dao-di herbs and their producing areas].

As a treasure of traditional Chinese medicine culture,Dao-di herbs are famous for their high quality and good effect.However,traditional characteristics of Dao-di herbs and their producing areas are mostly confined to qualitative description,lacking objective evaluation indicators. Numerical taxonomy,which uses mathematical methods to improve the research of taxonomy from qualitative description to quantitative comprehensive analysis,is objective and accurate,so is widely used in the field of biology and medicine.

Hydrogen sulfide treatment promotes glucose uptake by increasing insulin receptor sensitivity and ameliorates kidney lesions in type 2 diabetes.

Aims: To examine if hydrogen sulfide (H2S) can promote glucose uptake and provide amelioration in type 2 diabetes.

Results: Treatment with sodium hydrosulfide (NaHS, an H2S donor) increased glucose uptake in both myotubes and adipocytes. The H2S gas solution showed similar effects.

Hydrogen sulphide inhibits cardiomyocyte hypertrophy by up-regulating miR-133a.

Hydrogen sulphide (H(2)S) has been shown to play a crucial role in cardiovascular physiology and disease. However, there is no information about the possible role of H(2)S in cardiomyocyte hypertrophy (CH). Our results showed that pretreatment with NaHS, an H(2)S donor, significantly reduced [(3)H]-leucine incorporation, cell surface area, mRNA expression of brain natriuretic peptide (BNP), intracellular reactive oxygen species (ROS), miR-21 and increased atrial natriuretic peptide (ANP) and miR-133a expression in hypertrophic cardiomyocytes.

[Inhibitory effect of hydrogen sulfide on cardiac fibroblast proliferation].

The aim of the present study was to investigate the role of hydrogen sulfide (H(2)S) in the proliferation of neonatal rat cardiac fibroblasts (NRCFs). Proliferation of NRCFs was induced by the presence of fetal bovine serum (FBS) or angiotensin II (Ang II) at various concentrations. The concentration-dependent effect of NaHS (donor of H(2)S) on NRCFs proliferation was examined.
