Spatiotemporal variation and transport of Cs in the Beibu Gulf.

The temporal variation and transport of Cs in the Beibu Gulf (BG) are still poorly understood. Here we measured Cs concentrations in the BG water column and surface sediments during 2022. We found that Cs in the BG water column was controlled by the movement and mixing of local water masses.

Recent progress in understanding the role of bacterial extracellular DNA: focus on dental biofilm.

Dental biofilm is a highly complicated and dynamic structure comprising not only microbial communities but also the surrounding matrix of extracellular polymeric substances (EPS), including polysaccharides, proteins, extracellular DNA (eDNA) and other biopolymers. In recent years, the important role of bacterial eDNA in dental biofilms has gradually attracted attention. In this review, we present recent studies on the presence, dynamic conformation and release of oral bacterial eDNA.

Deciphering regulatory patterns in a mouse model of hyperoxia-induced acute lung injury.

Background: Oxygen therapy plays a pivotal role in treating critically ill patients in the intensive care unit (ICU). However, excessive oxygen concentrations can precipitate hyperoxia, leading to damage in multiple organs, with a notable effect on the lungs. Hyperoxia condition may lead to hyperoxia-induced acute lung injury (HALI), deemed as a milder form of acute respiratory distress syndrome (ARDS).

Unraveling the Origin of the Repulsive Interaction between Hydrogen Adsorbates on Platinum Single-Crystal Electrodes.

Hydrogen adsorption on platinum (Pt) single-crystal electrodes has been studied intensively in both experiments and computations. Yet, the precise origin and nature of the repulsive interactions observed between hydrogen adsorbates (H) have remained elusive. Here, we use first-principles density functional theory calculations to investigate in detail the interactions between H on Pt(111), Pt(100), and Pt(110) surfaces.

Site-specific bioorthogonal regulation of bone morphogenetic protein 2 expression for effective bone regeneration.

Growth factor holds great promise for bone regeneration, and spatiotemporal control of their expressing through site-specific reactions is crucial but challenging for on-demand therapy. In this study, we present the development of a novel unnatural amino acids (UAAs)-triggered therapeutic switch (UATS) system, composed of an orthogonal aminoacyl-tRNA-synthase (aaRS)-tRNA pair and a bone morphogenetic protein 2 (BMP2) gene harboring premature stop codon, which enable in situ and on-demand initiation of the expression of BMP2. The resulting UATS system allowed specifically control of base expressing on the BMP2 mRNA that switched to the BMP2 protein with complete structure and function to facilitate bone regeneration.

Daily dynamics of ground-dwelling invertebrate communities during and following an extreme high-temperature event in summer 2022, China.

The recent increase in the frequency of extreme weather events and declining soil biodiversity in global agricultural ecosystems make it crucial to assess the daily dynamics of soil communities in fields.

The aim of this study was to retrospectively analyze the clinical features and prognostic significance of CD117 in APL.

Advances in Circular RNA in the Pathogenesis of Epilepsy.

Recent studies evidenced the involvement of circular RNA (circRNA) in neuroinflammation, apoptosis, and synaptic remodeling suggesting an important role for circRNA in the occurrence and development of epilepsy. This review provides an overview of circRNAs considered to be playing regulatory roles in the process of epilepsy and to be involved in multiple biological epilepsy-related processes, such as hippocampal sclerosis, inflammatory response, cell apoptosis, synaptic remodeling, and cell proliferation and differentiation. This review covers the current research status of differential expression of circRNA-mediated seizures, m6A methylation, demethylation-mediated seizures in post transcriptional circRNA modification, as well as the mechanisms of m5C- and m7G-modified circRNA.

Shooting area of infrared camera traps affects recorded taxonomic richness and abundance of ground-dwelling invertebrates.

Ground-dwelling invertebrates are vital for soil biodiversity and function maintenance. Contemporary biodiversity assessment necessitates novel and automatic monitoring methods because of the threat of sharp reductions in soil biodiversity in farmlands worldwide. Using infrared camera traps (ICTs) is an effective method for assessing richness and abundance of ground-dwelling invertebrates.

Crosstalk of disulfidptosis-related subtypes identifying a prognostic signature to improve prognosis and immunotherapy responses of clear cell renal cell carcinoma patients.

Background: Disulfidptosis is a novel form of programmed cell death induced by high SLC7A11 expression under glucose starvation conditions, unlike other known forms of cell death. However, the roles of disulfidptosis in cancers have yet to be comprehensively well-studied, particularly in ccRCC.

Methods: The expression profiles and somatic mutation of DGs from the TCGA database were investigated.

Clinical Efficacy Analysis of Circumferential Upper Arm Liposuction with Double Incision: A Study of 496 Cases.

Background: In cases where the upper arm exhibits an irregular cylindrical appearance with subcutaneous fat concentrated primarily in the posterior lateral aspect, traditional localized fat suction techniques may lead to uneven or disharmonious results when addressing this concern. Many practitioners have turned to circumferential fat suction methods using multi-incision approaches to ensure effective results and fat removal. However, these methods often involve numerous incisions and complex procedures, necessitating the development of new, more efficient surgical techniques.

Background: Epilepsy's pathogenesis and progression are significantly influenced by neuroinflammation, blood-brain barrier function, and synaptic remodeling function. Matrix metalloproteinase 9 (MMP-9), as a critical factor, may contribute to the development of epilepsy through one or more of the above-mentioned pathways. This study aims to evaluate and quantify the correlation between MMP-9 levels and epilepsy.

Imbalanced EphB4/EphrinB2 Signaling Modulates Bone Resorption in Periodontitis Induced by .

Periodontitis, a chronic infectious disease in periodontal tissues, is characterized by an imbalance of alveolar bone resorption and remodeling, which eventually results in tooth loosening and even tooth loss. The etiology of periodontitis is polymicrobial synergy and dysbiosis, in which () is one of the primary pathogens responsible for periodontitis progression. The interplay of EphrinB2/EphB4 is crucial for osteoblast-osteoclast communication during bone remodeling and healing.

Associations of hyperthyroidism with epilepsy: a Mendelian randomization study.

Prior studies have revealed an increased susceptibility to epilepsy in hyperthyroid individuals, but the genetic basis of the hyperthyroidism-epilepsy relationship is not fully comprehended, prompting this study to explore this potential association. We conducted a two-sample Mendelian randomization (TSMR) study to explore the relationship between hyperthyroidism and epilepsy by utilizing aggregated statistics from Genome-Wide Association Studies (GWAS). Data for hyperthyroidism were derived from a GWAS encompassing 462,933 participants, while epilepsy data were sourced from the International League Against Epilepsy (ILAE) consortium.

Association between periodontitis and inflammatory comorbidities: The common role of innate immune cells, underlying mechanisms and therapeutic targets.

Periodontitis, which is related to various systemic diseases, is a chronic inflammatory disease caused by periodontal dysbiosis of the microbiota. Multiple factors can influence the interaction of periodontitis and associated inflammatory disorders, among which host immunity is an important contributor to this interaction. Innate immunity can be activated aberrantly because of the systemic inflammation induced by periodontitis.
