Gender Disparities and Lung Cancer Screening Outcomes Among Individuals Who Have Never Smoked.

Importance: Lung cancer in individuals who have never smoked (INS) is a growing global concern, with a rapidly increasing incidence and proportion among all lung cancer cases. Particularly in East Asia, opportunistic lung cancer screening (LCS) programs targeting INS have gained popularity. However, the sex-specific outcomes and drawbacks of screening INS remain unexplored, with data predominantly focused on women.

The role of mTOR activation in steroid-resistant asthma: insights from particulate matter-induced mouse model and patient studies.

Particulate matter (PM) exposure has been proposed as one of the causes of steroid resistance. However, studies investigating this using patient samples or animals are still lacking. Therefore, in this study, we aimed to investigate the changes in cytokines and mTOR (mammalian target of rapamycin) activation in patients with steroid resistant asthma and the role of mTOR in a mouse model of steroid resistant asthma induced by PM.

Effect of romosozumab on bone mineral density and trabecular bone score in premenopausal women with low bone mass.

Unlabelled: We investigated the efficacy of romosozumab in premenopausal women with low bone mass. Romosozumab substantially increased bone mineral density and trabecular bone score in these women, aligning with its proven therapeutic benefits for postmenopausal osteoporosis.

Purpose: Romosozumab, an anti-sclerostin antibody, is a promising anabolic agent that increases bone formation and decreases bone resorption.

The Road to Commercializing Optical Metasurfaces: Current Challenges and Future Directions.

Optical metasurfaces, components composed of artificial nanostructures, are recognized for pushing boundaries of wavefront manipulation while maintaining a lightweight, compact design that surpasses conventional optics. Such advantages align with the current trends in optical systems, which demand compact communication devices and immersive holographic projectors, driving significant investment from the industry. Although interest in commercialization of optical metasurfaces has steadily grown since the initial breakthrough with diffraction-limited focusing, their practical applications have remained limited by challenges such as, massive-production yield, absence of standardized evaluation methods, and constrained design methodology.

Mesoporous Boron-Doped Carbon with Curved BC Active Sites for Highly Efficient HO Electrosynthesis in Neutral Media and Air-Supplied Environments.

Hydrogen peroxide (HO) electrosynthesis via the 2e oxygen reduction reaction (ORR) is considered as a cost-effective and safe alternative to the energy-intensive anthraquinone process. However, in more practical environments, namely, the use of neutral media and air-fed cathode environments, slow ORR kinetics and insufficient oxygen supply pose significant challenges to efficient HO production at high current densities. In this work, mesoporous B-doped carbons with novel curved BC active sites, synthesized via a carbon dioxide (CO) reduction using a pore-former agent, to simultaneously achieve excellent 2e ORR activity and improved mass transfer properties are introduced.

Aerosol CVD Carbon Nanotube Thin Films: From Synthesis to Advanced Applications: A Comprehensive Review.

Carbon nanotubes (CNTs) produced by the floating-catalyst chemical vapor deposition (FCCVD) method are among the most promising nanomaterials of today, attracting interest from both academic and industrial sectors. These CNTs exhibit exceptional electrical conductivity, optical properties, and mechanical resilience due to their binder-free and low-defect structure, while the FCCVD method enables their continuous and scalable synthesis. Among the methodological FCCVD variations, aerosol CVD' is distinguished by its production of freestanding thin films comprising macroscale CNT networks, which exhibit superior performance and practical applicability.

Mice deficient in TWIK-1 are more susceptible to kainic acid-induced seizures.

TWIK-1 belongs to the two-pore domain K (K2P) channel family, which plays an essential role in the background K conductance of cells. Despite the development of exon 2-deleted knockout (KO) mice, the physiological role of TWIK-1 has remained largely unknown. Here, we observed that the exon 2-deleted KO mice expressed an internally deleted TWIK-1 (TWIK-1 ΔEx2) protein, which unexpectedly acts as a functional K channel.

ETV2/ER71 regulates hematovascular lineage generation and vascularization through an H3K9 demethylase, KDM4A.

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Neoadjuvant chemoradiotherapy up-regulates PD-L1 in radioresistant colorectal cancer.

Background: Combining radiotherapy (RT) with immune checkpoint inhibitors (ICIs) is a promising strategy that can enhance the therapeutic efficacy of ICIs. However, little is known about RT-induced changes in the expression of immune checkpoints, such as PD-L1, and their clinical implications in colorectal cancer (CRC). This study aimed to investigate the association between responsiveness to RT and changes in PD-L1 expression in human CRC tissue and cell lines.

Utilization of refuse-derived fuel in industrial applications: Insights from Uttar Pradesh, India.

Urbanization and population growth in India have quickened, leading to an annual generation of around 62 million tonnes of municipal solid waste (MSW). Improper management of organic waste presents a major environmental problem due to air and water pollution, soil contamination and greenhouse gas production. This research aims to develop refuse-derived fuel (RDF) as a viable option, converting waste into a high-calorific energy carrier for industrial use.

Optimizing Linezolid: Transforming It into a Selective MAO-B Inhibitor via a Toxicity-to-Activity Optimization Approach.

Linezolid, a widely used oxazolidinone antibiotic, exhibits potent activity against resistant bacterial infections but is associated with serotonergic toxicity, primarily due to its inhibition of monoamine oxidase (MAO). MAOs, consisting of MAO-A and MAO-B isoforms, play crucial roles in neurotransmitter metabolism, with implications for neurodegenerative disorders like Parkinson's and Alzheimer's diseases. This study aims to optimize Linezolid's structure to transform it into a selective MAO-B inhibitor.

Stoichiometric experiments and crystallographic studies characterize the catalytically relevant Ni complexes.

Multi-target-directed therapeutic strategies for Alzheimer's disease: controlling amyloid-β aggregation, metal ion homeostasis, and enzyme inhibition.

Alzheimer's disease (AD) is the most prevalent neurodegenerative dementia, marked by progressive cognitive decline and memory impairment. Despite advances in therapeutic research, single-target-directed treatments often fall short in addressing the complex, multifactorial nature of AD. This arises from various pathological features, including amyloid-β (Aβ) aggregate deposition, metal ion dysregulation, oxidative stress, impaired neurotransmission, neuroinflammation, mitochondrial dysfunction, and neuronal cell death.

A study on the measurement of the reference range of the whole blood viscosity in Thoroughbred horses.

This study aimed to measure the whole blood viscosity (WBV) in racehorses using a new viscometer and establish reference values, as well as to investigate the correlation between the WBV and the haematological parameters and serum chemistry. WBV measurements were conducted on 51 Thoroughbred horses using a novel U-shaped scanning capillary-tube viscometer. The reference values for the WBV were determined at various shear rates ranging from 1 s to 1 000 s.

Renal Outcomes With Renin-Angiotensin System Blockers After Unilateral Nephrectomy.

Introduction: Despite the benefits of renin-angiotensin system (RAS) blockers, their immediate use after nephrectomy has been limited because of concerns about impaired renal adaptation. We aimed to evaluate the effect of RAS blockers immediately after unilateral nephrectomy on renal adaptation.

Methods: This single-center retrospective cohort study included 580 patients who underwent elective unilateral nephrectomy between 2010 and 2020 and had preexisting hypertension with antihypertensive medications.
