First-principles study of hydrogen sulfide decomposition on Sc-TiCO single-atom catalyst.

Context: Hydrogen sulfide gas poses significant risks to both human health and the environment, with the potential to induce respiratory and neurological effects, and a heightened fatality risk at elevated concentrations. This article investigates the catalytic decomposition of HS on a Sc-TiCO single-atom catalyst(SAC) using the density functional theory-based first-principles calculation approach. Initially, the adsorption behavior of HS on TiCO-MXene was examined, revealing weak physical adsorption between them.

Excellent Catalytic Performance of ISOBAM Stabilized Co/Fe Colloidal Catalysts toward KBH Hydrolysis.

Recently, developing a cost-effective and high-performance catalyst is regarded as an urgent priority for hydrogen generation technology. In this work, ISOBAM-104 stabilized Co/Fe colloidal catalysts were prepared via a co-reduction method and used for the hydrogen generation from KBH hydrolysis. The obtained ISOBAM-104 stabilized CoFe colloidal catalysts exhibit an outstanding catalytic activity of 37,900 mL-H min g-Co, which is far higher than that of Fe or Co monometallic nanoparticles (MNPs).

The combination of aerobic and microaerobic promote hydrolysis and acidification of rice straw and pig manure: Balance of insoluble and soluble substrate.

Separated hydrolysis and acidification is an effective pretreatment method for anaerobic digestion of lignocellulose. However, excess consumption of soluble substrates remains a problem. Rice straw and pig manure were used as substrates with biogas slurry as the inoculum, combined with aerobic and microaerobic conditions in the 14-day hydrolysis and acidification.

Upregulation of BCAM and its sense lncRNA BAN are associated with gastric cancer metastasis and poor prognosis.

Patients with metastatic gastric cancer (GC) have a poor prognosis; however, the molecular mechanism of GC metastasis remains unclear. Here, we employed bioinformatics to systematically screen the metastasis-associated genes and found that the levels of basal cell adhesion molecule (BCAM) were significantly increased in GC tissues from patients with metastasis, as compared to those without metastasis. The upregulation of BCAM was also significantly associated with a shorter survival time.

The effect of a rehabilitation nursing intervention model on improving the comprehensive health status of patients with hand burns.

Aims And Objectives: To observe the effect of a rehabilitation intervention on the comprehensive health status of patients with hand burns.

Background: Most studies of hand-burn patients have focused on functional recovery. There have been no studies involving a biological-psychological-social rehabilitation model of hand-burn patients.

Reduced miR-125a-5p expression is associated with gastric carcinogenesis through the targeting of E2F3.

Emerging evidence suggests that altered expression of microRNAs (miRNAs) is involved in cancer progression. However, the role of miR-125a-5p in gastric carcinogenesis remains unknown. Quantitative real-time PCR analysis revealed that the expression of miR-125a-5p was significantly decreased in >80% of gastric cancer tissues compared with their adjacent non-tumor tissues, and was markedly reduced in ~95% of intestinal-type gastric cancer tissues.

Snail-regulated MiR-375 inhibits migration and invasion of gastric cancer cells by targeting JAK2.

MicroRNAs (miRNAs) have been reported to play a critical role in cancer invasion and metastasis. Our previous study showed that miR-375 frequently downregulated in gastric cancer suppresses cell proliferation by targeting Janus kinase 2 (JAK2). Here, we further found that the expression level of miR-375 is significantly decreased in metastatic gastric cancer tissues compared with the non-metastasis controls.

MiR-215 modulates gastric cancer cell proliferation by targeting RB1.

Growing evidence indicates that miRNAs play critical roles in tumorigenesis and cancer progression. Here, we report that miR-215 is significantly up-regulated in gastric cancer tissues from either gastrectomy or gastroscopy. Receiver Operator Characteristic (ROC) curve analysis indicated that miR-215 may be a candidate biomarker for gastric cancer diagnosis.

Biochemical evaluation of a synthesized isoflavone-selenium complex by molecular spectra.

A coordination compound of 5, 7-dihydrox-4'-methoxyisoflavone and selenium was synthesized and its structure was identified by IR, LC-MS and (1)H-NMR. Its biochemical effects were investigated using bovine serum albumin (BSA) as a target protein molecule, in which process three-dimensional (3D) fluorescence spectra, ultraviolet spectra, circular dichroism (CD) spectra and fluorescence probe techniques were employed. The interaction of SEIF and BSA was discussed by fluorescence quenching method and Förster non-radiation energy transfer theory.

Erythroid 5-aminolevulinate synthase mediates the upregulation of membrane band 3 protein expression by iron.

Iron deficiency leads to abnormal expression and function of band 3 protein in erythrocytes, but the underlying mechanisms remain elusive. The mRNA of erythroid-specific 5-aminolevulinate synthase (eALAS) contains an iron response element and the eALAS protein is an important mediator of iron utilization by erythrocytes. In this study, we investigated the effect of short hairpin RNA (shRNA) mediated silencing of eALAS on the expression of band 3 protein induced by iron.
