The rapid acceleration of global warming has led to an increased burden of high temperature-related diseases (HTDs), highlighting the need for advanced evidence-based management strategies. We have developed a conceptual framework aimed at alleviating the global burden of HTDs, grounded in the One Health concept. This framework refines the impact pathway and establishes systematic data-driven models to inform the adoption of evidence-based decision-making, tailored to distinct contexts.

Theoretical studies on the effect of bimetallic Au-based alloy catalysts on initial N electroreduction pathways at the present simulated electrode/aqueous interfaces based on DFT calculations are conducted in this work. The calculated results indicate that the alloying of Au with the transition metals Ni, Pd, Pt, Ru and Ta can facilitate the activation of N molecules in the presence of the electrode/aqueous interface, which may be derived from the kinetic overpotential of the outer Helmholtz plane. The N reduction pathway may be adsorption strength-dependent on N, in which the incorporation of transition metals with a strong chemical affinity for N molecules may lead to a dissociative mechanism the initial NN bond cleavage pathway, whereas the incorporation of transition metals with medium N binding strength may make N reduction proceed by the associative mechanism the initial NH formation pathway.

DNA-STR analysis is widely used in the forensic science field and obtaining results in shorter time is highly demanded. The developed forensic STR Kit, referred to as Expressmarker 16+10Y (EX16+10Y) and Expressmarker 16+18Y (EX16+18Y), could amplify the common autosomal and Y chromosome STR loci simultaneously. The kits are validated by a series of tests, including DNA mixtures, stutter ratios, PCR based studies, species specificities, inhibitors, sensitivity, sizing precision, reproducibility and parallel tests.

DNA-STR analysis is widely used in the forensic science field and has important requirements on the analysis time to obtain faster inspections. The developed forensic STR kit, referred to as Expressmarker 16 (EX16), could shorten the amplification time to a minimum of 35min. It enables 16 STR loci to be co-detected, including 13 CODIS loci, D2S1338, D6S1043 and Amelogenin loci.

Cas9/CRISPR has been reported to efficiently induce targeted gene disruption and homologous recombination in both prokaryotic and eukaryotic cells. Thus, we developed a Guide RNA Sequence Design Platform for the Cas9/CRISPR silencing system for model organisms. The platform is easy to use for gRNA design with input query sequences.

Objective: To explore the application value of Expressmarker 22 STR loci direct PCR amplification kit.

Methods: One thousand nine hundred and forty-eight samples (including samples spotted on FTA cards, filter papers and case samples) were tested using Expressmarker 22 STR loci direct PCR amplification kit. At the same time, all were tested using Sinofiler kit, Identifiler kit and PowerPlex 16 kit respectively for comparison.

Objective: To search for a method for increasing therapeutic effect on vitiligo.

Methods: One hundred and sixteen cases were randomly divided into a treatment group and a control group, 58 cases in each group. The treatment group were treated with electro-plum-blossom needle therapy plus catgut implantation at local acupoints under TDP radiation, and the control group with external application of sicorten.

Background & Objective: Recent studies have shown that overexpression of Fas associated phosphatase-1 (FAP-1) can been detected in human ovarian cancer cell line SKOV3, suggesting that this overexpression may play an important role in the tumorigenesis and drug resistance of ovarian cancer. This study was designed to explore the effects of fas associated phosphatase-1 antisense oligonucleotide (FAP-1 ASODN) combined with carboplatin on the apoptosis of ovarian cancer cell SKOV3.

Methods: Antisense oligonucleotide technique was used to transfect FAP-1 ASODN into SKOV3 cells.

Article Synopsis
  • - The study aimed to clone and express the PID domain of human DOC-2 (nDOC-2) in E. coli DH5alpha.
  • - Researchers used RT-PCR to amplify the nDOC-2 cDNA from ovarian tissue, cloned it into a vector, and confirmed the expression of the protein using SDS-PAGE.
  • - Successful expression of the PID domain in bacteria paves the way for future research on DOC-2's function and the development of antibodies against its protein.
