A Composite Pulse Excitation Technique for Air-Coupled Ultrasonic Detection of Defects in Wood.

To overcome the problems of the low signal-to-noise ratio and poor performance of wood ultrasonic images caused by ring-down vibrations during the ultrasonic quality detection of wood, a composite pulse excitation technique using a wood air-coupled ultrasonic detection system is proposed. Through a mathematical analysis of the output of the ultrasonic transducer, the conditions necessary for implementing composite pulse excitation were analyzed and established, and its feasibility was verified through COMSOL simulations. Firstly, wood samples with knot and pit defects were used as experimental samples.

Pd/Cu Catalyzed Asymmetric Allylation for Stereodivergent Synthesis of Glutamic Acid Derivatives.

A synergistic Pd/Cu catalyst system has been developed for stereodivergent transformation of Morita-Baylis-Hillman (MBH) carbonates and Schiff bases derived from simple amino acids to afford a series of optically active β-branched γ-methyleneglutamic acid derivatives with adjacent tertiary/tertiary and quaternary/tertiary stereocenters in high yields (up to 96 %) with excellent diastereo- and enantioselectivities (>20/1 dr and >99 % ee in most cases) under mild conditions. The use of SKP ligand is disclosed to be crucial for the success of the transformation, and in particular allowing the reaction to proceed at low catalyst loading (0.02 mol % for Pd and 0.

Association of Lactate with Risk of Cardiovascular Diseases: A Two-Sample Mendelian Randomization Study.

Purpose: Studies consistently show abnormally high levels of lactate acid in cardiovascular disease patients, suggested that targeting lactate production may serve as potential strategies for the treatment in the future. However, observational results may be subject to residual confounding and bias.

Methods: This study used the dataset from GWAS database to examine confounding in epidemiologic associations between lactate and cardiovascular diseases.

Lovastatin enhances humoral and cellular immune responses to H1N1 influenza vaccine.

The Swine Influenza Virus (SIV) is a major respiratory pathogen in swine, causing acute, febrile, and highly transmissible infections. This virus is widespread globally and poses significant risks to human health and social development. Traditional prevention strategies for SIV rely on the use of inactivated vaccines combined with Alum adjuvants.

Ruthenium-Catalyzed Carbocycle-Selective Hydrogenation of Fused Heteroarenes.

The homogeneous catalytic hydrogenation of benzo-fused heteroarenes generally provides partially hydrogenated products wherein the heteroaryl ring is preferentially reduced, such as quinoline hydrogenation, leading to 1,2,3,4-tetrahydroquinoline. Herein, we report a carbocycle-selective hydrogenation of fused -heteroarenes (quinoline, isoquinoline, quinoxaline, etc.) using the Ru complex of a chiral spiroketal-based diphosphine (SKP) as the catalyst, affording the corresponding 5,6,7,8-tetrahydro products in high chemoselectivities.

Artificial intelligence algorithms for real-time detection of colorectal polyps during colonoscopy: a review.

Colorectal cancer (CRC) is one of the most common cancers worldwide. Early detection and removal of colorectal polyps during colonoscopy are crucial for preventing such cancers. With the development of artificial intelligence (AI) technology, it has become possible to detect and localize colorectal polyps in real time during colonoscopy using computer-aided diagnosis (CAD).

Elucidating the mechanism of action of astragalus polysaccharide on ionizing radiation-induced myocardial damage based on network pharmacology and experimental research.

Due to the unavoidable impact of ionizing radiation on the heart located near the mediastinum, varying degrees of myocardial damage may occur. As a result, the clinical application of radiotherapy in cancer treatment is significantly limited. However, the molecular mechanisms underlying radiation-induced heart disease (RIHD) are not yet fully understood, and there is a lack of disease-specific treatment strategies.

Reconstituting the immune killing functions and improving the pharmacokinetics of nanobodies by rhamnolipid conjugation.

Nanobodies (Nbs) hold great promise as next-generation cancer immunotherapies, but their efficacy is hindered by their poor pharmacokinetics and the inability to trigger Fc-mediated immune killing functions. To address these limitations, we designed and synthesized rhamnolipid-modified Nbs as a type of antibody-recruiting molecule by site-specifically conjugating EGFR-targeting Nb 7D12 to a series of rhamnolipid derivatives, and their biological profiles were evaluated in vitro and in vivo. Investigation of the structure-activity relationship revealed that the number of rhamnose (Rha) units and the length of the PEG linker in the conjugates affected anti-tumor activities.

Associations Between Heavy Metal Exposure from Milk and Steroid Hormones in Mothers.

[Spatial-temporal Distribution and Ecological Risk of Antibiotics in the Soils of a Typical Agricultural Watershed in the Three Gorges Reservoir Area].

In order to understand the spatial-temporal distribution and ecological risk of antibiotics in the soil of an agricultural watershed in the Three Gorges Reservoir area, the topsoil samples were collected at 26 sites in the Wangjiagou small watershed, Fuling District, Chongqing in spring, summer, autumn, and winter of 2022, and 21 antibiotics with five classes were determined using solid phase extraction and ultra-performance liquid chromatography-tandem mass spectrometry. The content levels and spatial-temporal distribution of antibiotics were analyzed, the correlations between antibiotic contents and soil physicochemical factors were discussed, and the potential ecological risk of antibiotics in the soil was evaluated using the risk quotient method. The results showed that the detection rates of 21 antibiotics were 0-100% with the range of ND-219.

Ferroptosis in Osteoarthritis: Towards Novel Therapeutic Strategy.

Osteoarthritis (OA) is a chronic, degenerative joint disease primarily characterised by damage to the articular cartilage, synovitis and persistent pain, and has become one of the most common diseases worldwide. In OA cartilage, various forms of cell death have been identified, including apoptosis, necroptosis and autophagic cell death. Ever-growing observations indicate that ferroptosis, a newly-discovered iron-dependent form of regulated cell death, is detrimental to OA occurrence and progression.
