Gaudichaudione H (GH) is a naturally occurring small molecular compound derived from Garcinia oligantha Merr. (Clusiaceae), but the full pharmacological functions remain unclear. Herein, the potential of GH in disulfidptosis regulation, a novel form of programmed cell death induced by disulfide stress is explored.

Dissemination of genes associated with antibiotic resistance and bacterial virulence during ecosystem succession in two Tibetan glacier forefields.

The release of pathogens and DNA from the cryosphere (glacier, permafrost, and, sea ice) has become a new threat to society and environment. Due to enhanced glacier retreat, the size of glacier forefields has greatly expanded. Herein, we used a combination of metagenomic and metatranscriptomic methods and adopted a sequence-based approach to investigate the distribution and changing patterns of virulence factor genes (VFGs) and antibiotic resistance genes (ARGs) in two glacier forefields.

Regional-specific trends of PM and O temperature sensitivity in the United States.

Climate change poses direct and indirect threats to public health, including exacerbating air pollution. However, the influence of rising temperature on air quality remains highly uncertain in the United States, particularly under rapid reduction in anthropogenic emissions. Here, we examined the sensitivity of surface-level fine particulate matter (PM) and ozone (O) to summer temperature anomalies in the contiguous US as well as their decadal changes using high-resolution datasets generated by machine learning.

Serologic detection of regenerating protein I alpha by time-resolved fluoroimmunoassay and its clinical value in gastric cancer.

Background: Regenerating protein I alpha (REG Iα) plays a key role in the progression of gastric cancer (GC). However, the clinical application value of serum REG Iα in GC remains largely unknown.

Methods: Serum REG Iα levels were analyzed through time-resolved fluoroimmunoassay (TRFIA) in healthy controls (HCs) and patients with benign gastric disease (BGD) and GC.

The economic consequences of local gas leaks with evidence from Massachusetts housing market.

This study provides the first empirical evidence of the impact of leaks in natural gas distribution pipelines on nearby home prices. Using high-resolution property transaction data in Massachusetts and a difference-in-differences approach, we find that gas leaks significantly reduce nearby home prices by 2.61% ($11,700) on average.

Mate-Pair Sequencing Enables Identification and Delineation of Balanced and Unbalanced Structural Variants in Prenatal Cytogenomic Diagnostics.

Background: Mate-pair sequencing detects both balanced and unbalanced structural variants (SVs) and simultaneously informs in relation to both genomic location and orientation of SVs for enhanced variant classification and clinical interpretation, while chromosomal microarray analysis (CMA) only reports deletion/duplication. Herein, we evaluated its diagnostic utility in a prospective back-to-back prenatal comparative study with CMA.

Methods: From October 2021 to September 2023, 426 fetuses with ultrasound anomalies were prospectively recruited for mate-pair sequencing and CMA in parallel for prenatal genetic diagnosis.

Mechanical Force-Induced cGAS Activation in Carcinoma Cells Facilitates Splenocytes into Liver to Drive Metastasis.

Liver metastasis is the main cause of cancer-related mortality. During the metastasis process, circulating carcinoma cells hardly pass through narrow capillaries, leading to nuclear deformation. However, the effects of nuclear deformation and its underlying mechanisms on metastasis need further study.

Assessing inequities in electrification via heat pumps across the US.

Heat pumps are an energy-efficient and increasingly cost-effective solution for reducing greenhouse gas emissions in the building sector. However, other clean energy technologies, such as rooftop solar, are less likely to be adopted in underserved communities, and thus policies incentivizing their adoption may funnel support to well-resourced communities. Unlike previously studied technologies, the effects of heat pumps on household energy bills may be positive or negative depending on local climate, energy costs, building features, and other factors.

Surgical effect of the medial wall resection of the cavernous sinus for functional pituitary adenomas.

Background: The surgical treatment of pituitary adenomas (PAs) is aimed at achieving maximal tumor resection, relieving the compression, and correcting the disorders of pituitary hormones. Parasellar dural invasion is a primary factor in the failure of the surgery. By comparing the two operations of tumor excision combined with resection of the medial wall of the cavernous sinus (MW) and simple tumor excision, we further confirmed the clinical effectiveness and safety of the resection technique of the MW.

The mechanism of all-trans retinoic acid-induced cleft palate may be related to the novel ENSMUST00000159153-miR-137-5p-Wnt7a and ENSMUST000000236086-miR-34b-3p-EphA10/TRPM2 ceRNA crosstalk.

Cleft palate is the most prevalent congenital condition. Cleft palate is brought on by an exogenous chemical called all-trans retinoic acid (atRA). In order to indirectly control gene expression, long chain non-coding RNAs (lncRNAs) act as competitive endogenous RNA (ceRNA) sponges.

Deciphering endocrine function of adipose tissue and its significant influences in obesity-related diseases caused by its dysfunction.

Current research has found that adipose tissue is not only involved in energy metabolism, but also a highly active endocrine organ that secretes various adipokines, including adiponectin, leptin, resistin and apelin, which are involved in the regulation of physiology and pathology of tissues and organs throughout the body. With the yearly increasing incidence, obesity has become a risk factor for a variety of pathological changes, including inflammation and metabolic syndrome in various system (endocrine, circulatory, locomotor and central nervous system). Thus these symptoms lead to multi-organ dysfunctions, including the heart, liver, kidneys, brain and joints.

Lycopene's therapeutic mechanisms in epididymitis: a network pharmacology and experimental study.

Background: Epididymitis, a common disease of the male reproductive system, is often caused by nonspecific infections. Antibiotics alone cannot reverse histopathological changes or prevent long-term reproductive issues. Lycopene (LYC), a potent antioxidant, has shown potential in alleviating epididymitis, yet its specific mechanisms remain unclear.

CuP/CoP Heterostructure for Efficient Electrosynthesis of Ammonia from Nitrate Reduction Reaction.

Electrocatalytic nitrate reduction (ENORR) for ammonia production is one of the potential alternatives to Haber-Bosch technology for the realization of artificial ammonia synthesis. However, efficient ammonia production remains challenging due to the complex electron transfer process in ENORR. In this study, we fabricated a CuP/CoP heterostructure on carbon cloth (CC) by electrodeposition and vapor deposition, which exhibits an exceptional ENORR performance in alkaline medium, and showcases a Faradaic efficiency of ammonia (FE) and an ammonia yield rate as high as 97.

Modeling the Global Impact of Chlorine Chemistry on Secondary Organic Aerosols.

Simulation of secondary organic aerosol (SOA) in models has been an uncertain component in determining the impacts of atmospheric aerosols on air quality and climate. Recent studies have shown that reactive chlorine can rapidly oxidize volatile organic compounds (VOCs), trigger SOA formation, and alter other oxidants, thus having a potentially significant effect on SOA, which has not been thoroughly investigated at the global scale. Here, we developed a chlorine-SOA simulation within a global chemical transport model along with updated anthropogenic continental chlorine emissions.

Diversity of primary vegetation species of lake shore impacts largely carbon emissions in thermokarst lakes on the Qinghai-Tibet plateau.

Terrestrial organic matter from surrounding primary vegetation is critical for carbon cycling in thermokarst lakes. However, the characteristics and contribution of this vegetation in shaping microbial community and affecting carbon emissions in thermokarst lakes remain poorly understood. This study quantifies the influence of lakeshore primary vegetation characteristics on microbial community and carbon emissions across lakes with different vegetation types on the Qinghai-Tibet Plateau (QTP).

New mechanisms of PM induced atherosclerosis: Source dependent toxicity and pathogenesis.

Exposure to fine particulate matter (PM) is recognized to induce atherosclerosis, but the underlying mechanisms are not fully understood. This study used ambient PM samples collected in one of the highly polluted regions of Guanzhong Plain in China (2017-2020) and an ApoE mouse model to investigate the association between exposure to PM and atherosclerosis. Despite a substantial decrease in the ambient concentration of PM from 266.

Effect of carrageenan on stability and 3D printing performance of high internal phase pickering emulsion stabilized by soy protein isolate aggregates under neutral condition.

High internal phase Pickering emulsion (HIPPE) stabilized by heat induced soy protein isolate aggregates (HSPI) alone had limited stability and poor 3D printing performance. While there is few research about HIPPE stabilized by HSPI and polysaccrides at neutral pH condition, where HSPI and ĸ-carrageenan (CG) were combined to fabricate HIPPE in this research. It was found that the incorporation of CG significantly decreased the droplet size and improved the storage stability of the resulting HIPPE.
