Early life experience modulates resilience to stress in later life. Previous research implicated maternal care as a key mediator of behavioral responses to the adversity in adolescence, but details of molecular mechanisms remain elusive. Here, we show social stress activates transcription factor C/EBPβ in mPFC neurons of adolescent mice, which transcriptionally upregulates Dnm1l and promotes mitochondrial dysfunction, thereby conferring stress susceptibility in adolescent mice.

The novelty of this study lies in providing the first large-scale real-world clinical data to evaluate the effectiveness and safety of CRT on chronic glomerulopathy and to explore potential molecular mechanisms.
Methods: This is a single-arm retrospective study in the real-world.
Background: Immune checkpoint blockade (ICB) inhibits tumor immune escape and has significantly advanced tumor therapy. However, ICB benefits only a minority of patients treated and may lead to many immune-related adverse events. Therefore, identifying factors that can predict treatment outcomes, enhance synergy with ICB, and mitigate immune-related adverse events is urgently needed.

Molecular dynamics simulations are a valuable tool for studying the behavior of mixed surfactant systems at the air-water interface. We have conducted molecular dynamics simulations to investigate the interfacial behavior of a mixed cationic-anionic surfactant system, including -[3-(dimethylamino)propyl]perfluorobutanesulfonamide hydrochloride (PFB-MC) and 1-octanesulfonic acid (1-OA).

With the development of artificial intelligence technology and the growing demand for minimally invasive surgery, the intelligentization of minimally invasive surgery has become a current research hotspot. Surgical instrument segmentation is a highly promising technology that can enhance the performance of minimally invasive endoscopic imaging systems, surgical video analysis systems, and other related systems. This article summarizes the semantic and instance segmentation methods of minimally invasive surgical instruments based on deep learning, deeply analyzes the supervision methods of training algorithms, network structure improvements, and attention mechanisms, and then discusses the methods based on the Segment Anything Model.

However, the factors that regulate α-Syn pathology and nigrostriatal dopaminergic degeneration remain poorly understood. Previous studies demonstrate cholesterol 24-hydroxylase (CYP46A1) increases the risk for PD.

The purpose of this study is to investigate their differences in intratumoral microvessels, related angiogenic factors and important stromal cells.
Methods: Thirty patients (15 paired patients only with GGO or SN) diagnosed with pathological stage 0-I lung adenocarcinoma who underwent surgical treatment were included into this study.
Purification of soot particles from automobile exhaust has closely to do with the synergistic effect between catalyst metals. Here, several binary Ni-Fe oxide catalysts were elaborately prepared via a modified solvothermal method. A non-noble-metal (Ni)-modified hexagonal FeO nano-sheet catalyst (Ni-FeO) was prepared.
View Article and Find Full Text PDFA series of 3DOM LaKSrCoO catalysts were synthesized using colloidal crystal templating and citric acid complexation methods. The substitution of K ions for A-site La ions was found to markedly enhance the catalysts' intrinsic activity, with the LaKSrCoO catalyst showing exceptional performance comparable to commercial precious metal catalysts. The LaKSrCoO catalyst demonstrated the highest catalytic activity, with T, T, and T values of 280 °C, 335 °C, and 387 °C, respectively.

Objectives: To elucidate the dose-response relationship between lipids and all-cause mortality in the dialysis population.
Methods: Computer searches of PubMed, Embase, Web of Science, CNKI, and Wanfang.
Background: Differentiation between ulcerative colitis (UC) and other intestinal inflammatory diseases is difficult, and the precise etiology of UC is poorly understood. Thus, there is a need for novel diagnostic and prognostic biomarkers for UC.
Methods: Intestinal mucosal biopsy tissue specimens of inflamed (ulcerative colitis-inflamed, UC-I) and non-inflamed (ulcerative colitis-noninflamed, UC-N) tissue were obtained simultaneously during colonoscopy from newly diagnosed UC patients prior to any treatments.
Background: Macrophages play a crucial role in the pathological process after myocardial infarction (MI). However, pharmacological therapy targeting this pathway remains undefined. Curcumol, a natural compound extracted from the Curcumae Rhizoma, has demonstrated anti-tumor and anti-inflammatory activities.

Identifying drug targets, especially within complex systems such as the p53 pathway, remains a formidable task. The regulation of this pathway by myriad stress signals and regulatory elements adds layers of complexity to the discovery of effective p53 pathway activators.

In contrast to transcriptional dynamics during liver repair, its metabolic dependencies remain poorly defined. Here, we screened metabolic genes differentially regulated during liver regeneration, and report that SLC13A2, a transporter for TCA cycle intermediates, is decreased in rapid response to partial hepatectomy in mice and recovered along restoration of liver mass and function.

Herein, the high-dispersion CuO clusters supported on the well-defined CeO nanorods were prepared using the complex deposition slow method. The formation of heteroatomic Cu-O-Ce interfacial structural units as active sites can capture electrons to achieve activation of the NO and O molecules.

For numerical simulation, one three-dimensional thoracic aortic geometry model with an LSA stent graft retrograde curved orientation was reconstructed from post-TEVAR computed tomography angiography (CTA) images, and four potential LSA graft configurations were modified and reconstructed: three straight (0, 2, and 10 mm aortic extension) and one anterograde configuration. The blood perfusion of the LSA, flow field, and hemodynamic wall parameters were analyzed.
