In heterogeneous tumors, adjacent CpG sites form methylation haplotype blocks (MHBs), genomic regions where methylation status reflects local epigenetic concordance. While MHBs have been implicated in gene dysregulation, their pan-cancer dynamics and clinical relevance remain unclear. We profiled 110 primary tumors across 11 common solid cancer types, identifying 81,567 MHBs.

Aerosol oxidative potential (OP), as a key indicator characterizing its ability to generate reactive oxygen species (ROS), is directly related to the health effects of particulate matter. After a systematic review of global studies, it was found that the sensitivity of major OP measurement assays to chemical components varies significantly, and the regional pollution characteristics show a sharp contrast, which is mainly driven by biomass combustion, industrial emissions, and secondary transformation, etc. The mechanism of OP generation is complex, involving transition metal catalysis, redox of organics, such as Humus-like substances (HULIS), the synergistic effect of metal-organic complexation, and endotoxin (LPS) stimulation of inflammatory response.

Crop selenium uptake, influenced by complex factors, has prompted extensive research to predict the Se content in crop grains, leading to the development of various prediction methods. However, the practical application of these models is limited by geographical constraints and variations in independent variables. This study selected two distinct regions in Guangdong Province, China: the Pearl River Delta (PRD), a Quaternary plain region, and Heyuan, a hilly region characterized by outcrops of clastic rocks.

Vitis rupestris metacaspase 5, tethered to microtubules, drives grapevine. Hypersensitive response via calcium-dependent auto-processing, linking cytoskeletal dynamics to defence activation by elicitors. Metacaspase 5 is a key player for the hypersensitive response of grapevine against biotrophic pathogens and must be activated rapidly as to prevent colonisation.

Background: Accurate measurement of endometrial thickness (ET) using transvaginal ultrasound (TVUS) imaging is essential for diagnosing various gynecological conditions. However, manual ET measurement remains challenging, especially for junior physicians, due to variability in image quality and patient characteristics.

Methods: A prospective observational study was performed using a dataset of 976 uterine ultrasound videos (82,063 images) measured in 2014-2019 in Tongji Hospital, Huazhong University of Science and Technology.

Uterine sarcomas are rare and aggressive tumors with heterogeneous outcomes, making accurate risk stratification crucial for personalized treatment. This study introduced a novel semi-supervised clustering approach, survival-guided adaptive Kmeans (SGAKmeans), for enhanced mortality risk stratification in early-stage uterine sarcoma patients. SGAKmeans uniquely integrated clinical characteristics and survival information, leveraging domain knowledge and soft pairwise constraints to adaptively adjust distance calculations.

Timely diagnosis of endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) is crucial, yet traditional hysteroscopy faces accuracy challenges. This study introduces ECCADx, a deep learning-based computer-aided diagnosis system utilizing contrastive learning for hysteroscopic identification of AEH and EC. This is the system to integrate contrastive learning for this specific differentiation.

Objectives: Interstitial lung diseases (ILDs) and pulmonary sarcoidosis represent a group of disorders characterized by diffuse parenchymal lung damage and chronic inflammation, leading to impaired lung function and gas exchange. These conditions may ultimately result in progressive respiratory failure and increased mortality. This study aimed to assess the global, regional, and national burden of ILDs and pulmonary sarcoidosis.

Many patients with chronic prostatitis (CP)/chronic pelvic pain syndrome (CPPS) also experience depression, although the pathogenesis was unclear. Some studies have shown that gut microbiota disorder might be related to both prostatitis and depression. Therefore, we investigated the alteration of the gut microbiota in autoimmune CP/CPPS complicated with depression in a rat model.

Zinc (Zn) is an essential micronutrient that regulates plant growth, immunity and antiviral defence mechanisms. However, its limited bioavailability often necessitates excessive application, resulting in inefficiencies in production and environmental stress. In response, we propose an environmentally friendly and sustainable approach to enhance the utilization of Zn.

Micro- & nano-plastics (MNPs) have been considered an emerging persistent pollutant in the environment. Most of the works focus on the potential toxicity of pristine, rather than photoaged, MNPs, let alone the underlying mechanisms of toxicity. To address this gap, we exposed human liver cancer cells (HepG2) to polystyrene nanoplastics (PS-NPs) with varying degrees of photodegradation, including pristine PS-NPs and photoaged PS-NPs irradiated with UV for 8 days (short-term) and 32 days (long-term).

With the intensification of global warming, there is an urgent need to develop crops with enhanced heat tolerance. Pearl millet, as a typical C4 heat-tolerant crop, has mechanisms of heat tolerance at the cellular level which remain unclear. Constructed single-cell transcriptomic landscape of pearl millet leaves under heat stress and normal conditions, comprising 20 589 high-quality cells classified into five cell types.

Triptolide (TP) is a promising anti-tumor candidate derived from the herb Tripterygium wilfordii, but its poor water solubility and multi-organ toxicity limit its application. Here, we developed novel nanoparticles (TP-SP@NPs) modified with dextran sulfate and RGD peptide for double-targeted delivery of TP to both tumor cells and pro-tumor macrophages in pancreatic cancer treatment. TP-SP@NPs exhibited suitable particle size (about 98 nm), good stability and controlled release performance.

Size and shape are critical discriminators between molecular species and states. We describe a microchip-based high-throughput imaging approach offering rapid and precise determination of molecular properties under native solution conditions. Our method detects differences in molecular weight across at least three orders of magnitude and down to two carbon atoms in small molecules.

Methods: In MSU-induced mice, 36 male C57BL/6 mice were randomly divided into 6 groups of 8 mice each group, including the control group, model group, RUT low-, medium-, and high-doses groups, and prednisone acetate group. The mice in each group were orally administered the corresponding drugs or vehicle once a day for 7 consecutive days.

Fatty acyl desaturases (Fads) are known to play critical roles in the biosynthesis of long-chain polyunsaturated fatty acids (LC-PUFAs) in fish species. To date, research on Fads in fish has predominantly focused on Fads2, while studies on Fads1 have been rarely reported. Acipenseriformes, commonly known as Chondrostei, are an ancient fish lineage with unique evolutionary history.
