The domestic and international research status was reviewed, analyzing the explosion characteristics of inert powders, active powders, and composite powder explosion suppressants from the perspectives of maximum explosion pressure and flame propagation properties. The explosion suppression mechanisms of powder suppressants were also summarized. Analysis found that the inert powder is mainly from the physical aspects of heat absorption, oxygen dilution, and the formation of physical barriers to inhibit gas explosions; the active powder is mainly from the chemical aspects of the capture of free radicals to interrupt the explosion chain reaction inhibition of gas explosions; the composite powder is through the physical-chemical aspects of synergistic inhibition of gas explosions.

Here, we investigate the diversity, distribution, and metabolic potential of MGII archaea in the Eastern Indian Ocean using high-throughput sequencing and metagenomic analyses. We identified 37 MGII operational taxonomic units(OTUs), with surface and deep chlorophyll maximum (DCM) layers dominated by clade O1, O3, and P, and deeper waters by O4 and H, reflecting depth-specific ecological niches shaped by environmental gradients.

Adding L-Lys to the PPI emulsion resulted in a decrease in particle size and uniform distribution, the stability of emulsion was increased, and the gel exhibited higher elastic (G'), better stability and more compact microstructure was formed. Especially when 0.

The Hengduan Mountains region is sensitive to climate change. Although many dendrochronological studies have been conducted in this region, few researches examined seasonal variations of stem radial growth and their responses to environmental factors of subalpine coniferous tree species. We monitored stem radial variations of four dominant coniferous species .

Mandibular advancement devices are effective in treating mild or moderate obstructive sleep apnea (OSA), but such devices that are commonly used in clinical settings require further improvement. In this study, we evaluated the clinical effects of personalized adjustable mandibular advancement devices on mild or moderate OSA. Forty patients with mild or moderate OSA were randomly divided into experimental (personalized adjustable device) and control (traditional device) groups.

However, the precise molecular mechanisms through which signaling pathways regulate key transcription factors controlling erythropoiesis and megakaryopoiesis remain partially understood. Herein, we identified heat shock cognate B (HSCB), which is well known for its iron-sulfur cluster delivery function, as an indispensable protein for friend of GATA 1 (FOG1) nuclear translocation during erythropoiesis of K562 human erythroleukemia cells and cord-blood-derived human CD34+CD90+hematopoietic stem cells (HSCs), as well as during megakaryopoiesis of the CD34+CD90+HSCs.

The findings indicate that the variations in creep primarily stem from temperature changes, whereas humidity changes have little influence on fluctuations in both basic creep and total creep. The influence of humidity on creep is more strongly reflected in the magnitude of creep.

Background And Objective: Lung cancer is the most fatal malignant tumor in the world. Since the discovery of driver genes, targeted therapy has been demonstrated to be superior to traditional chemotherapy and has revolutionized the therapeutic landscape of non-small cell lung cancer (NSCLC). The remarkable success of tyrosine kinase inhibitors (TKIs) in patients with epidermal growth factor receptor () mutations and anaplastic lymphoma kinase () fusions has shifted the treatment from platinum-based combination chemotherapy to targeted therapy.

Phosphoinositide-3 kinases δ/γ (PI3Kδ/γ) play an important role in the maintenance of effective immunity, especially for Tregs homeostasis and stability. In the present study, superoxide dismutase A (SodA) stimulation was used to establish the sarcoidosis mouse model.

Human urine-derived stem cells (hUSCs) process self-renewal and multilineage differentiation ability. Due to their non-invasive and easily available clinical source, hUSCs represent a promising alternative source of mesenchymal stem cells (MSCs) for application potential in cytotherapy. However, technical limitations, such as stemness property maintenance, have hindered hUSCs' clinical application.

Because of the high drought sensitivity of tomatoes, water stress inhibits their nutrient uptake, leading to a decrease in tomato quality and yield. Therefore, the rapid, accurate and non-destructive detection of water status is important for scientifically and effectively managing tomato water and fertilizer, improving the efficiency of water resource utilization, and safeguarding tomato yield and quality.

Deep generative modeling, aiming to learn complex data distributions, is a promising approach to tackle the conformation generation problem. Here, inspired by stochastic dynamics and recent advances in generative modeling, we developed SDEGen, a novel conformation generation model based on stochastic differential equations.

In recent years, the prevention and control of water pollution has received extensive attention. There is a need to develop simple and effective strategies for the rapid detection of metal ions and dissolved organic matter (DOM) in order to improve water quality. To this end, the first copper nanoclusters (CuNCs)-based fluorescent sensor array was done to identify 12 metal ions (Pb, Fe, Cu, Cd, Cr, Co, Ni, Zn, Ag, Fe, Hg, and Al) and DOM (humic substances, lipids, fatty acids, amino acids, and lignans).

Autologous hematopoietic stem cell transplantation (AHSCT) has been a novel strategy for patients with new-onset T1D, but not for those with a later diagnosis. Disturbance of regulatory T cells (Tregs) likely contributes to poor response after transplantation in later-stage T1D.

Unlabelled: Demand-responsive technologies are rapidly changing the transportation landscape. The City of Belleville, Ontario has recently replaced its evening and nighttime fixed route bus service with an on-demand transit (ODT) service. Preliminary reports have found a 300% increase in nighttime bus ridership since the implementation of this service, yet to fully understand the social return on the investment in on-demand services, we must also quantify whether and for whom these new services have enabled time savings and increased levels of activity participation.

Subterranean estuaries, the mixing zone between terrestrial groundwater and coastal seawater, are important biogeochemical hotspots. In the present study, organic carbon cycling and related drivers, including the characterization of different organic carbon pools and sediment microbial community, were investigated in a subterranean estuary seepage face. Within the first 20 cm depth seepage face sediments, both production and removal of dissolved organic carbon (DOC) were observed, mainly driven by heterotrophic microbes.
