Esophageal cancer is a highly prevalent gastrointestinal tumor in China, resulting in a significant number of deaths annually. In this paper, we investigated the regulatory role and therapeutic potential of aberrant ST7-AS1 expression in esophageal cancer. The presence of ST7-AS1 in 125 esophageal cancer tissues was identified through RT-qPCR assays.

Comprehending the spatial-temporal characteristics, contributions, and evolution of driving factors in agricultural non-CO greenhouse gas (GHG) emissions at a macro level is pivotal in pursuing temperature control objectives and achieving China's strategic goals related to carbon peak and carbon neutrality. This study employs the Intergovernmental Panel on Climate Change (IPCC) carbon emissions coefficient method to comprehensively evaluate agricultural non-CO GHG emissions at the provincial level. Subsequently, the contributions and spatial-temporal evolution of six driving factors derived from the Kaya identity were quantitatively explored using the Logarithmic Mean Divisia Index (LMDI) and Geographical and Temporal Weighted Regression (GTWR) methods.

Objective: Mucosal immunization was an effective defender against pathogens. Nasal vaccines could activate both systemic and mucosal immunity to trigger protective immune responses. However, due to the weak immunogenicity of nasal vaccines and the lack of appropriate antigen carriers, very few nasal vaccines have been clinically approved for human use, which was a major barrier to the development of nasal vaccines.

Direct compaction (DC) is considered to be the most effective method of tablet production. However, only a small number of the active pharmaceutical ingredients (APIs) can be successfully manufactured into tablets using DC since most APIs lack adequate functional properties to meet DC requirements. The use of suitable modifiers and appropriate co-processing technologies can provide a promising approach for the preparation of composite particles with high functional properties.

Large-scale measurements of soil moisture play a critical role in many fields, such as agriculture, hydrology, and engineering. The distributed temperature sensing (DTS) technology, based on a dual-probe heat pulse (DPHP), is a novel approach to realizing large-scale soil moisture estimation. However, the application of the method is limited by the complex optical cable layout, calculation algorithm, and lack of standardized heating strategy.

Article Synopsis
  • Celangulin V, a natural sesquiterpene polyester, has shown anti-insect activity through a unique mechanism targeting the H subunit of V-ATPase in insect midguts.
  • Researchers synthesized thirty-two benzene sulfonamide derivatives to find cost-effective insecticides, with several compounds (C2, C4, C5, C6, and C8) demonstrating significantly higher efficacy than Celangulin V, with lower LC50 values.
  • Molecular docking studies suggest that these new sulfonamide compounds effectively interact with the H subunit of V-ATPase, making them promising candidates for developing efficient insecticidal agents.

This paper examines the effects of different loading patterns on the static characteristics of continuous concrete beams reinforced with external prestressed carbon fiber-reinforced polymer tendons (EPCFRPT) and qualitatively analyzes the results for two continuous concrete beams: SB-1 under symmetrical loading, and SB-2 under asymmetrical loading. Then, a finite element analysis model is introduced and calibrated by tests conducted at Southeast University and data collected from a literature review. Based on the FEA model, the initial prestress, cross-section area, and eccentricity of CFRP tendons as well as the steel reinforcement configuration were selected by a parametric study.

Microplastics (MPs), which are widely present in the natural environment, may be harmful to the growth and health of aquatic organisms, though studies in this area are lacking. In this study, the crucian carp (), a type of omnivorous freshwater fish, was chosen as the target, which was fed with fish food containing different concentrations of MPs for a 30-day food exposure experiment to study the effects of MPs on crucian growth, liver damage, and gut microbiome composition. Compared with that in the control group, the body length of the crucians in the environmental groups did not change significantly.

Despite the apparent improvement in air quality in recent years through a series of effective measures, the concentration of PM and O in Chengdu city remains high. And both the two pollutants can cause serious damage to human health and property; consequently, it is imperative to accurately forecast hourly concentration of PM and O in advance. In this study, an air quality forecasting method based on random forest (RF) method and improved ant colony algorithm coupled with back-propagation neural network (IACA-BPNN) are proposed.

In our previous studies, a kind of novel benzenesulfonamides was found to be a candidate insecticidal compounds. It was shown that propargyloxy and sulfonamide groups are pharmacodynamic groups. One hundred and twenty-six (126) naphthalenesulfonamides derivatives with propargyloxy functionality were designed and synthesized, and their insecticidal activities were determined.

Cardiac dysfunction in severe sepsis is associated with increased mortality. However, the molecular mechanisms underlying septic heart dysfunction remain unclear. Expression of peroxisome proliferator-activated receptor-γ coactivator 1α (Pgc-1α), concentrations of inflammatory factors, and activation of the nuclear factor kappa-B (NF-κB) signaling pathway were examined in H9c2 cells after a 24-h lipopolysaccharide (LPS) stimulation period using qPCR, enzyme-linked immunosorbent assays (ELISAs), and western blots (WBs), respectively.

The present study aimed to investigate the expression of inflammatory markers and mitochondrial function-related genes, as well as their temporal relationship with cardiac myocyte injury in a rat model of sepsis. The sepsis model was constructed using cecal ligation and puncture (CLP). Two hours after CLP, the levels of inflammatory cytokines (interleukin [IL]-1β, IL-6, and TNFα) and myocardial function markers (serum brain natriuretic peptide [BNP], cardiac troponin-I [cTNI], and procalcitonin [PCT]) were increased significantly, falling from around 9 hours postoperatively.
