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.

Molecular H as the Reducing Agent in Low-Temperature Oxide Reduction Using Calcium Hydride.

Low-temperature synthesis is crucial for advancing sustainable manufacturing and accessing novel metastable phases. Metal hydrides have shown great potential in facilitating the reduction of oxides at low temperatures, yet the underlying mechanism─whether driven by H, H, or atomic H─remains unclear. In this study, we employ electrical transport measurements and first-principles calculations to investigate the CaH-driven reduction kinetics in epitaxial α-FeO thin films.

Activation of Immune Responses Through the RIG-I Pathway Using TRITC-Dextran Encapsulated Nanoparticles.

Pathogen-associated molecular patterns (PAMPs) are highly conserved motifs originating from microorganisms that act as ligands for pattern recognition receptors (PRRs), which are crucial for defense against pathogens. Thus, PAMP-mimicking vaccines may induce potent immune activation and provide broad-spectrum protection against microbes. Dextran encapsulation can regulate the surface characteristics of nanoparticles (NPs) and induces their surface modification.

Clinical Outcomes of Patients With Newly Diagnosed Acute Myeloid Leukemia Receiving Treatment in a Safety-Net Hospital System.

Background: 'Standard of care' therapies for adult acute myeloid leukemia (AML) have yielded 5-year overall survival (OS) rates of 30%-45 %. Risk stratification and novel targeted therapies have improved 5-year OS rates to >75 % for certain groups in specialized centers.

Patients And Methods: This is a retrospective cohort analysis of outcomes in patients ≥18 years with newly diagnosed AML treated between 2005 and 2019 in the Harris Health County, Safety-Net Hospital System in Houston, TX.

One-Step Synthesis of 2-Arylquinolin-4(1)-Ones from 1-(2-Aminoaryl)-3-Arylpropan-1-Ones via Pd(II)-Catalyzed Dehydrogenative Cyclization.

In this study, we developed palladium-catalyzed dehydrogenative cyclization to transform 1-(2-aminoaryl)-3-arylpropan-1-ones into 2-arylquinolin-4(1)-ones, also known as aza-flavones which are the bioisosteres of flavones, in an atom-economic manner. This method exhibited excellent chemical compatibility with a broad substrate scope, accommodating up to 25 derivatives. Additionally, kinetic studies were performed to elucidate the reaction mechanism.
