The mechanism-specific injury mortality burden associated with heatwave in China in a warming world.

Numerous studies have investigated the impact of heatwaves on non-accidental mortality, yet the association and burden of heatwaves on mechanism-specific injury mortality remain underexplored. This study collected 257,267 injury-related fatalities and corresponding daily maximum temperatures (DMT) across seven Chinese provinces from 2013 to 2023. A heatwave was characterized by two or more successive days where the DMT surpassed its 92.

Arbuscular mycorrhizal fungi mitigate cadmium stress in maize.

Soil cadmium (Cd) pollution poses a significant environmental threat, impacting global food security and human health. Recent studies have highlighted the potential of arbuscular mycorrhizal (AM) fungi to protect crops from various heavy metal stresses, including Cd toxicity. To elucidate the tolerance mechanisms of maize in response to Cd toxicity under AM symbiosis, this study used two maize genotypes with contrasting Cd tolerance: Zhengdan958 (Cd-tolerant) and Zhongke11 (Cd-sensitive).

Metastatic sites of baseline as predictors in recurrent or metastatic nasopharyngeal carinoma treated with PD-L1 inhibitor: a secondary analysis of multicenter, single-arm, phase II study (KL-A167).

Background: Immune checkpoint inhibitors (ICIs) show optimal treatment effects on recurrent or metastatic nasopharyngeal carcinoma(R/M NPC). Nonetheless, whether metastatic sites impact ICIs efficacy remains unclear.

Methods: We performed a secondary analysis of R/M NPC patients treated with KL-A167, a programmed cell death-ligand 1(PD-L1) inhibitor, based on a multicenter, single-arm, phase II study from China between 2019 and 2021 years, which represents the first and most comprehensive analysis of the effectiveness of a PD-L1 inhibitor in patients who have been previously treated.

Endo 180 participates in collagen remodeling of the periodontal ligament during orthodontic tooth movement.

Background: Orthodontic tooth movement (OTM) relies on the remodeling of periodontal tissues, including the periodontal ligament (PDL) and alveolar bone. Collagen remodeling plays a crucial role during this process, allowing for the necessary changes in the PDL's structure and function. Endo180, an urokinase plasminogen activator receptor-associated protein, is a transmembrane receptor regulated collagen remodeling.

Comparative efficacy of multiple non-invasive brain stimulation to treat major depressive disorder in older patients: A systematic review and network meta-analysis study based on randomized controlled trials.

Background: Major depressive disorder (MDD) is prevalent among older patients and is frequently associated with cognitive decline and a reduced quality of life. Non-invasive brain stimulation (NIBS) techniques show promise for treating MDD, but their comparative efficacy and safety older populations remain unclear. This study aimed to compare the efficacy and cognitive effects of various NIBS techniques in treating MDD in older patients.

Sphk1/S1P pathway promotes blood-brain barrier breakdown after intracerebral hemorrhage through inducing Nlrp3-mediated endothelial cell pyroptosis.

Intracerebral hemorrhage (ICH) is a severe stroke subtype with high mortality and limited therapeutic options. The blood-brain barrier (BBB) breakdown post-ICH exacerbates secondary brain injury, highlighting the need for targeted therapies to preserve the BBB integrity. We aim to investigate the role of the Sphk1/S1P pathway in BBB breakdown following ICH and to evaluate the therapeutic potential of Sphk1 inhibition in mitigating this breakdown.

The role of mitochondrial DNA copy number in female infertility: a bidirectional two-sample Mendelian randomization study.

Background: Previous studies on the impact of mitochondrial DNA (mtDNA) copy number on female infertility were limited and inconsistent.

Methods: The causal relationship between mtDNA copy number and female infertility was evaluated using a bidirectional 2-sample Mendelian randomization (MR) method. Inverse variance weighted (IVW) method was applied for principal analysis, and MR-Egger, weighted median, simple mode, weighted mode method for secondary analyses.

Comprehensive analysis of the value of angiogenesis and stemness-related genes in the prognosis and immunotherapy of ovarian cancer.

Tumor angiogenesis and the presence of cancer stem cells (CSCs) are critical characteristics of tumors. Previous research has demonstrated that cancer stem cells promote tumor angiogenesis, while increased vascularity, in turn, fosters the growth of cancer stem cells. This creates a detrimental cycle that contributes to tumor progression.

Individual and joint associations between sleep duration and physical activity with cognitive function: A longitudinal analysis among middle-aged and older adults in China.

Introduction: Studies using cross-sectional data or with a short follow-up period fail to distinguish whether the associations between sleep duration and physical activity with cognitive function result from reverse causation.

Methods: The longitudinal study examined the individual and joint associations, with specific temporality, between sleep duration and physical activity with cognitive function, using time-lagged linear mixed models and generalized additive mixed models.

Results: A total of 14,694 participants aged ≥ 50 years were included, with an average lagged time of 4.

Phase angle as a prognostic factor in patients with cancer: a systematic review of the existing evidence via a meta-analysis.

Background: the phase angle (PA) is expressed via bioelectrical impedance and an indicator of cell membrane health, integrity, hydration, and nutritional status. The associations between PA and cancer survival are inconsistent and unclear. This study aimed to assess PA's role as a prognostic marker of cancer survival.

Differences in Gut Microbial Composition and Characteristics Among Three Populations of the Bamboo Pitviper ().

The gut microbiota contributes to host health by facilitating nutrient uptake, digestion, energy metabolism, intestinal development, vitamin synthesis, and immunomodulation, and plays an important role in the growth and reproduction of the animal itself. Considering the paucity of research on the gut microbiota of wild snakes, this study focused on bamboo pitviper () populations from Anhui, Guizhou, and Hunan, with multiple fecal samples collected from each population (six, five, and three, respectively). Total microbial DNA was extracted from the fecal samples using metagenomic next-generation sequencing and differences in gut microbial composition, abundance, and carbohydrate-active enzymes (CAZymes) were analyzed and compared among the three populations.

Decidualization-associated recruitment of cytotoxic memory CD8T cells to the maternal-fetal interface for immune defense.

Decidual CD8T (dCD8T) cells are pivotal in the maintenance of the delicate balance between immune tolerance towards the fetus and immune resistance against pathogens. The endometrium and decidua represent the uterine environments before and during pregnancy, respectively, yet the composition and phenotypic alterations of uterine CD8T cells in these tissues remain unclear. Using flow cytometry and analysis of transcriptome profiles, we demonstrated that human dCD8T and endometrial CD8T (eCD8T) cells exhibited similar T cell differentiation statuses and phenotypes of tissue infiltrating or residency, compared to peripheral CD8T (pCD8T) cells.
