Theory of Pressure Dependence of Superconductivity in Bilayer Nickelate La_{3}Ni_{2}O_{7}.

A recent experiment showed the superconducting transition temperature in the Ruddlesden-Popper bilayer La_{3}Ni_{2}O_{7} decreases monotonically with increasing pressure above 14 GPa. In order to unravel the underlying mechanism for this unusual dependence, we performed theoretical investigations by combining the density functional theory (DFT) and the unbiased functional renormalization group (FRG). Our DFT calculations show that the Fermi pockets are essentially unchanged with increasing pressure (above 14 GPa), but the bandwidth is enlarged, and particularly the interlayer hopping integral between the nickel 3d_{3z^{2}-r^{2}} orbitals is enhanced.

World and Human Action Models towards gameplay ideation.

Generative artificial intelligence (AI) has the potential to transform creative industries through supporting human creative ideation-the generation of new ideas. However, limitations in model capabilities raise key challenges in integrating these technologies more fully into creative practices. Iterative tweaking and divergent thinking remain key to enabling creativity support using technology, yet these practices are insufficiently supported by state-of-the-art generative AI models.

Hunting for heroes: Brain neurons mediating GLP-1R agonists in obesity treatment.

Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RAs) have proven to be highly effective in reducing obesity across species and ages, gaining unmet popularity in clinical treatments against obesity. Although extensive research efforts have been made to explore how the brain regulates body weight homeostasis including the effect brought up by GLP-1 and its synthetic analogs GLP-1RAs, the identity of neurons and neural pathways that are responsible for the observed anti-obesity effect of GLP-1RAs remain largely elusive. Excitingly, three recent high-profile studies presented compelling evidence that each argues for the importance of GLP-1Rs in the dorsomedial hypothalamus, hindbrain, or lateral septum, respectively, in mediating the anti-obesity effect of GLP-1RAs.

Renal Tubular Epithelial Cell-Derived hsa_circ_0008925 From Urine Is Related to Chronic Renal Fibrosis.

Renal fibrosis (RF) is a crucial pathological factor in the progression of chronic kidney disease (CKD) to end-stage renal failure, and accurate and noninvasive assays to monitor the progression of renal fibrosis are needed. Circular RNAs (circRNAs) are noncoding RNAs that can be used as diagnostic biomarkers and therapeutic targets for human diseases. In this study, we analysed the expression of hsa_circ_0008925 in human urinary renal tubular cells and investigated its role in renal fibrosis.

Exosomes derived from TREM-2 knocked-out macrophages alleviated renal fibrosis via HSPa1b/AKT pathway.

Macrophages are recognized as vital players in renal fibrosis, with a high degree of heterogeneity and plasticity, and the triggering receptor expressed on myeloid cell-2 (TREM-2) is highly expressed on macrophages and participates in the progression of tissue fibrosis. However, the mechanism by which TREM-2 mediates the progression of renal fibrosis is still unclear. Our study revealed that exosomes derived from TREM-2-deficient (TREM-2) macrophages suppressed the progression of fibrosis, as indicated by a greater matrix metalloproteinase-9 (MMP-9)/tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) ratio at the protein level in secreted exosomes than in exosomes from wild-type (WT) macrophages in the fibrotic microenvironment.

Dynamic formation mechanism of persistent free radicals driven by water-phase oxidation-dependent heterogeneity of the carbon-silicon coupling structure in biochar.

The formation of persistent free radicals (PFRs) in biochar (BC) is closely related to the structural characteristics and reactivity of BC, which have toxic effects on the environment. However, the mechanisms driving PFRs formation through structural evolution during oxidative aging of BC remain unclear. Herein, we propose a novel dynamic mechanism for BC-PFRs formation driven by oxidation-dependent heterogeneity in carbon-silicon coupling structures by evaluating their heterogeneous correlations, sequential responses, and synergistic relations.

Melatonin attenuates hepatic oxidative stress by regulating the P62/LC3 autophagy pathway in PCOS.

The elevated level of hepatic oxidative stress (OS) in polycystic ovary syndrome (PCOS) is one of the important causes of liver abnormalities. Therefore, decreasing the level of hepatic OS in PCOS is beneficial to reduce the risk of PCOS-related liver diseases. Melatonin (MT), recognized as a potent antioxidant.

Construction and analysis of protein-protein interaction network for esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is a prevalent malignant tumor of the digestive tract. Clinical findings reveal that the five-year survival rate for mid-to late-stage ESCC patients is merely around 20 %, whereas those diagnosed at an early stage can achieve up to a 95 % survival rate. Consequently, early detection is paramount to improving ESCC patient survival.

[Association of metal/metalloids exposure with abnormal liver function among occupational population in a mining area of Hunan Province:a prospective study].

Objective: To investigate the association of metals/metalloids exposure with risk of liver disfunction among occupational population in Hunan Province, and to explore the potential dose-response relationship.

Methods: In 2017, a mining area in Hunan Province was chosen as the research site, and eligible workers were recruited as study subjects. General demographic characteristics, levels of 23 metals/metalloids in plasma and urine, and liver function index(total bilirubin(TBIL), alanine amino transferase(ALT), globulin(GLB) and γ-glutamyl transferase(GGT)) were obtained by questionnaire, physical examination and laboratory tests.

Exposure risks of lead and other metals to humans: A consideration of specific size fraction and methodology.

Particle size is a critical influencing factor in assessing human exposure risk as fine particles are generally more hazardous than larger coarse particles. However, how particle composition influences human health risk is only poorly understood as different studies have different utilised different definitions and as a consequence there is no consensus. Here, with a new methodology taking insights of each size fraction load (%GSF), metal bioaccessibility, we classify which specific particle size can reliably estimate the human exposure risk of lead and other metals.

Ticagrelor regulates the differentiation of MDSCs after acute myocardial infarction to reduce cardiac injury.

Myeloid-derived suppressor cells (MDSCs) are important participants after acute myocardial infarction (AMI), but the role of their different subtypes in AMI remains controversial. The anti-inflammatory effect of ticagrelor in AMI has been discovered. However, the detailed anti-inflammatory mechanism has not been fully demonstrated.

Molecular-level insights into the temperature-dependent formation dynamics and mechanism of water-soluble dissolved organic carbon derived from biomass pyrolysis smoke.

Herein, we explored the molecular-level formation mechanism of pyrolytic smoke-derived WSOC in water to explain the evolution, heterogeneous correlations, and sequential responses of molecules and functional groups to increasing pyrolysis temperature.

Herein, we explored a molecular‒level formation mechanism for polystyrene MP (MP)‒derived DOM (PSDOM) during the photoaging of MPs to explain the evolution, heterogeneity, and sequential response of molecules to irradiation.

Emerging Signaling Regulation of Sinoatrial Node Dysfunction.

Purpose Of Review: The sinoatrial node (SAN), the natural pacemaker of the heart, is responsible for generating electrical impulses and initiating each heartbeat. Sinoatrial node dysfunction (SND) causes various arrhythmias such as sinus arrest, SAN block, and tachycardia/bradycardia syndrome. Unraveling the underlying mechanisms of SND is of paramount importance in the pursuit of developing effective therapeutic strategies for patients with SND.
