Targeting ferroptosis: a promising approach for treating lung carcinoma.

Lung carcinoma incidence and fatality rates remain among the highest on a global scale. The efficacy of targeted therapies and immunotherapies is commonly compromised by the emergence of drug resistance and other factors, resulting in a lack of durable therapeutic benefits. Ferroptosis, a distinct pattern of cell death marked by the buildup of iron-dependent lipid peroxides, has been shown to be a novel and potentially more effective treatment for lung carcinoma.

Bisphenol F (BPF) exposure impairs sperm quality and offspring development in male zebrafish.

Background: Bisphenol F (BPF), a substitute for bisphenol A (BPA), is widely used in consumer products, increasing the potential for environmental exposure. Our study investigated the reproductive effects of BPF on adult male zebrafish and explored its toxicological mechanisms, as well as its intergenerational effects.

Methods: Adult male zebrafish were exposed to BPF concentrations of 0, 50, 500, 2500, and 5000 nM for 21 days.

The brain-gut microbiota network (BGMN) is correlated with symptom severity and neurocognition in patients with schizophrenia.

The association between the human brain and gut microbiota, known as the "brain-gut-microbiota axis", is involved in the neuropathological mechanisms of schizophrenia (SZ); however, its association patterns and correlations with symptom severity and neurocognition are still largely unknown. In this study, 43 SZ patients and 55 normal controls (NCs) were included, and resting-state functional magnetic resonance imaging (rs-fMRI) and gut microbiota data were acquired for each participant. First, the brain features of brain images and functional brain networks were computed from rs-fMRI data; the gut features of gut microbiota abundance and the gut microbiota network were computed from gut microbiota data.

Degradation of antibiotic pollutants and simultaneous CO capture over hollow MnO/light/peroxymonosulfate (PMS)-CaO system.

Antibiotic organic pollutants not only pose a significant threat to human health but also generate a large amount of carbon dioxide (CO) during the treatment process of advanced oxidation processes (AOPs). Herein, the antibiotics aqueous solution was firstly degraded and mineralized by light-assisted peroxymonosulfate (PMS) activation over hollow manganese dioxide (MnO) catalyst and then the corresponding released CO was effectively captured by calcium oxide (CaO) particles in the same sealed reactor, achieving wastewater treatment with zero carbon releasing. Under simulated light conditions, hollow MnO is excited to generate electron-hole pairs.

Role of Leucine-Rich Repeat-Containing G-Protein-Coupled Receptors 4-6 (LGR4-6) in the Ovary and Other Female Reproductive Organs: A Literature Review.

Leucine-rich repeat-containing G-protein-coupled receptors regulate stem cell activity and tissue homeostasis within female reproductive organs, primarily through their interaction with the Wnt/β-catenin signaling pathway. LGR4-6 are increasingly recognized for their roles in organ development, regeneration, and cancer. This review aims to provide a comprehensive overview of the roles of LGR4-6 in female reproductive organs, highlighting their significance in normal physiology and disease states, specifically in the context of ovarian cancer.

Superstrong Lightweight Aerogel with Supercontinuous Layer by Surface Reaction.

Breaking the thermal, mechanical and lightweight performance limit of aerogels has pivotal significance on thermal protection, new energy utilization, high-temperature catalysis, structural engineering, and physics, but is severely limited by the serious discrete characteristics between grain boundary and nano-units interfaces. Herein, a thermodynamically driven surface reaction and confined crystallization process is reported to synthesize a centimeter-scale supercontinuous ZrO nanolayer on ZrO-SiO fiber aerogel surface, which significantly improved its thermal and mechanical properties with density almost unchanged (≈26 mg cm). Systematic structure analysis confirms that the supercontinuous layer achieves a close connection between grains and fibers through Zr─O─Si bonds.

Stromal architecture and fibroblast subpopulations with opposing effects on outcomes in hepatocellular carcinoma.

Dissecting the spatial heterogeneity of cancer-associated fibroblasts (CAFs) is vital for understanding tumor biology and therapeutic design. By combining pathological image analysis with spatial proteomics, we revealed two stromal archetypes in hepatocellular carcinoma (HCC) with different biological functions and extracellular matrix compositions. Using paired single-cell RNA and epigenomic sequencing with Stereo-seq, we revealed two fibroblast subsets CAF-FAP and CAF-C7, whose spatial enrichment strongly correlated with the two stromal archetypes and opposing patient prognosis.

Enhancing Electron Donor-Acceptor Complex Photoactivation with a Stable Perylene Diimide Metal-Organic Framework.

Electron donor-acceptor complexes are commonly employed to facilitate photoinduced radical-mediated organic reactions. However, achieving these photochemical processes with catalytic amounts of donors or acceptors can be challenging, especially when aiming to reduce catalyst loadings. Herein, we have unveiled a framework-based heterogenization approach that significantly enhances the photoredox activity of perylene diimide species in radical addition reactions with alkyl silicates by promoting faster and more efficient electron donor-acceptor complex formation.

Radiographic Soft Tissue Thickness is not a Risk Factor for Infection after Primary Total Ankle Arthroplasty.

As the incidence of total ankle arthroplasty (TAA) for the management of end-stage arthritis is on the rise, identification of risk factors for periprosthetic joint infection (PJI) is essential. There has been limited research exploring the use of radiographic soft tissue thickness in TAA despite its predictive value in other forms of arthroplasty. This study evaluated the predictive capabilities of radiographic soft-tissue thickness for PJI following TAA.

Obstructive sleep apnea and structural and functional brain alterations: a brain-wide investigation from clinical association to genetic causality.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.

Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

Physical unclonable in-memory computing for simultaneous protecting private data and deep learning models.

Fluorescence-enhanced detection of sulfide ions through tuning the structure-activity relationship of gold nanoclusters.

The concentration of S is a vital environmental indicator for evaluating the quality of source water, surface water, and wastewater, and it has a significant impact on biological systems, particularly human health. Therefore, it is crucial to detect S selectively and sensitively.

Ultrasensitive Chemiresistive Gas Sensors Based on Dual-Mesoporous Zinc Stannate Composites for Room Temperature Rice Quality Monitoring.

The integration of dual-mesoporous structures, the construction of heterojunctions, and the incorporation of highly concentrated oxygen vacancies are pivotal for advancing metal oxide-based gas sensors. Nonetheless, achieving an optimal design that simultaneously combines mesoporous structures, precise heterojunction modulation, and controlled oxygen vacancies through a one-step process remains challenging. This study proposes an innovative method for fabricating zinc stannate semiconductors featuring dual-mesoporous structures and tunable oxygen vacancies via a direct solution precursor plasma spray technique.

Tannic Acid Modulates Voltage-gated K+ Channels to Promote Neuritogenesis in Neuronal N2A Cells.

In a previous report, we showed that voltage-gated K+ (Kv) Kv1 and Kv2 channels are involved in cAMP-induced neuritogenesis of mouse neuronal N2A cells. In this report, we examined the effects of tannic acid (TA) on Kv channels and neuritogenesis in N2A cells. TA (15 μM) mildly enhanced Kv currents at -30 to -20 mV but strongly inhibited Kv currents at higher voltages, causing a preferential activation of currents at low voltages.
