Morphological and Physiological Resource Trade-Offs Affect the Response of Poa pratensis to Urban Shading

The shading of urban buildings and understory space has a severe impact on cold-season turfgrass urban greening. To explore the effect of shading stress on the typical cold-season turfgrass of Poa pratensis, the six shading gradients of 0% (full light, CK, 6 × 104 lux), 20% (1-la...

Integrative identification and preliminary validation of senescence-associated secretory phenotype-related candidate biomarkers in type 2 diabetes

Senescence-associated secretory phenotype (SASP)-related inflammatory programs have been implicated in type 2 diabetes mellitus (T2DM), yet blood-based candidates have not been systematically screened and validated across independent cohorts. We adopted standardized senescence si...

Heterogeneities by Age and Sex in Associations Between Electronic Device Use Frequency and Comorbid Mental Health Symptoms: The Roles of Self-Efficacy and Social Support

Objectives: This study aims to examine age and sex disparities in the relationships between the weekly frequency of electronic device use and mental health comorbidities (anxiety symptoms, depressive symptoms, and stress), and the roles of self-efficacy and social support. Method...

Fetal hypoxia causes oocyte oxidative stress damage via the Sirt3/Sod2 pathway and can be alleviated by nicotinamide mononucleotide.

Environmental hypoxia exerts detrimental effects on the reproductive capabilities of both humans and animals. A fetal hypoxia model was established in which fetal mice were kept in a high-plateau hypoxic setting from embryonic day (E) 0 to 16.5. In our previous research, we found...

A multi-channel modal fusion hypergraph convolutional neural network for Tibetan medicinal material classification

The key to the digital and intelligent development of Tibetan medicine lies in the accurate identification of Tibetan medicinal plants. To address the challenges in Tibetan medicine identification—such as the susceptibility of small image targets to occlusion, interference from s...

Beyond Recanalization: Neurovascular Unit Protection and Precision Adjunctive Therapy for Ischemic Stroke in the Reperfusion Era

Intravenous thrombolysis and endovascular thrombectomy (EVT) have increased large-vessel recanalization in acute ischemic stroke, yet macrovascular reopening does not ensure tissue reperfusion or functional recovery. Microvascular no-reflow, blood–brain barrier failure, oxidative...

Solar‐Driven Photocatalytic H 2 O 2 Production: Mechanistic Foundations, Catalyst Design, Performance Benchmarking, and Sustainable Applications

ABSTRACT Hydrogen peroxide (H 2 O 2 ) is a clean oxidant, disinfectant, and candidate liquid energy carrier, yet its industrial manufacture remains dominated by the energy‐intensive anthraquinone process. Solar photocatalytic H 2 O 2 synthesis offers a decentralized alternative t...

Topological Reinforcement of Rhizosphere Microbial Networks Facilitates the Invasive Superiority of Spartina anglica

Rhizosphere microbial interaction patterns underpin the resilience and dominance of invasive plants in fluctuating coastal salt marshes. We compared the rhizosphere microbial communities of the invasive Spartina anglica and the native Spartina maritima across varying distances fr...

Triple primary cancer with concurrent detection of two tumor components in a lung biopsy specimen: a case report

Multiple primary cancers (MPCs) are uncommon, and triple primary cancers are particularly rare. Their diagnosis and treatment are challenging because they can be mistaken for recurrence or distant metastasis, resulting in missed or incorrect diagnoses. A 70-year-old Chinese man u...

Cooling Architecture Optimization and PUE Modelling for Hyperscale AI Data Centres in High-Altitude Low-Pressure Environments: A Case Study on the Qinghai–Tibetan Plateau

Preprint of a modelling study on cooling architecture selection for hyperscale AI data centres located at high altitude, where atmospheric pressure is only 70-80 kPa and air density falls to about 80% of its sea-level value. The rapid scaling of artificial-intelligence (AI) compu...

The hypoxia–gut microbiota–bile acid axis: mechanistic crosstalk and therapeutic opportunities

Hypoxia is a central feature of a wide range of pathological conditions; however, the metabolic regulatory networks underlying hypoxic adaptation remain incompletely understood. In recent years, accumulating evidence suggests that bile acids, traditionally regarded as metabolic e...

Small mammalian herbivores at moderate densities facilitate livestock growth by improving vegetation composition in grasslands

Small mammals and large herbivores have co-evolved in grasslands for millions of years, yet how they interplay remains unclear. Although large herbivores can significantly affect the smaller ones, the reversal effect is largely unknown. On the Qinghai–Tibetan Plateau, plateau pik...

Identifying the influencing factors of lake surface greenhouse gas concentrations using sentinel-2 remote sensing and machine learning: A case study of bird Island, Qinghai Lake

Alpine lakes on the Qinghai-Tibet Plateau are important regions for studies of the regional carbon cycle and are highly sensitive to climate change. However, the variation patterns of lake surface greenhouse gases and their environmental regulation mechanisms remain unclear. In t...

Mn-Modified MIL-100(Fe)-Derived FeOx to Boost Toluene Photothermal Catalytic Degradation

The development of highly efficient catalysts is important for the photothermal catalytic oxidation of volatile organic compounds (VOCs). Herein, MIL-100(Fe) was used as the sacrificial template to prepare MnFeOx catalysts with different Mn contents through the impregnation–calci...

Multiscale mechanical characteristics and slope protection effects of herbaceous roots in the loess region of the Qinghai–Tibet Plateau

Abstract Background The Xining Basin, located at the confluence of the northeastern Qinghai–Tibet Plateau and the western Loess Plateau, where extensive loess deposits are found, is densely inhabited. Major transport corridors, encompassing the Qinghai–Tibet Railway and the Lanzh...

The transcriptome construction and microbial succession pattern in the intestinal tract of 3–5 month-old yak calves

Abstract This study investigated age-dependent intestinal development in yak calves by integrating intestinal morphology, 16S rRNA sequencing, and jejunal transcriptome analyses across 3, 4, and 5 months of age. Results demonstrated progressive intestinal maturation characterized...

First Isolation and Genomic Characterization of BVDV-1c in Przewalski’s Gazelle (Procapra przewalskii) from the Qinghai–Tibet Plateau, China

Przewalski’s gazelle (Procapra przewalskii) is an endangered ungulate endemic to the Qinghai–Tibet Plateau of China. Increasing habitat alteration and close contact with domestic livestock have raised concerns about cross-species pathogen transmission, yet infectious disease stud...

Temporal Variations in Runoff and Seasonal Climatic Associations in Selected Headwater Catchments of the Yangtze and Yellow Rivers

The source regions of the Yangtze and Yellow Rivers on the Tibetan Plateau provide vital water resources for downstream ecosystems and populations, yet their runoff responses to climate warming remain insufficiently understood. Based on daily runoff data from six hydrological sta...
