Omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties.

Due to the outbreak of global public health emergency, antibacterial fabrics such as face masks are in great demand. However, common antibacterial fabrics cannot kill bacteria in minutes and they are easy to be contaminated and lost biological activity. In this work, omnipotent antibacterial cotton fabrics with superhydrophobic and photothermal properties are developed by the combination of dopamine with copper sulfide (CuS) and silver nanoparticles on cotton fabrics, and post-modification with PDMS.

TDP1 represents a promising therapeutic target for overcoming tumor resistance to chemotherapeutic agents: progress and potential.

Tyrosyl-DNA phosphodiesterase 1 (TDP1) is an enzyme that plays a crucial role in repairing DNA lesions caused by the entrapment of DNA topoisomerase IB (TOP1)-DNA break-associated crosslinks. TDP1 inhibitors exhibit synergistic effects with TOP1 inhibitors in cancer cells, effectively overcoming resistance to TOP1 inhibitors. Therefore, this approach presents a promising strategy for reversing tumor resistance to TOP1 inhibitors.

Advances in genetically modified neural stem cell therapy for central nervous system injury and neurological diseases.

Neural stem cells (NSCs) have increasingly been recognized as the most promising candidates for cell-based therapies for the central nervous system (CNS) injuries, primarily due to their pluripotent differentiation capabilities, as well as their remarkable secretory and homing properties. In recent years, extensive research efforts have been initiated to explore the therapeutic potential of NSC transplantation for CNS injuries, yielding significant advancements. Nevertheless, owing to the formation of adverse microenvironment at post-injury leading to suboptimal survival, differentiation, and integration within the host neural network of transplanted NSCs, NSC-based transplantation therapies often fall short of achieving optimal therapeutic outcomes.

Solvent-responsive covalent organic framework membranes for precise and tunable molecular sieving.

Membrane-based nanofiltration has the potential to revolutionize the large-scale treatment of organic solvents in various applications. However, the widely used commercial membranes suffer from low permeability, narrow structural tunability, and limited chemical resistance. Here, we report a strategy for fabricating covalent organic framework (COF) membranes with solvent-responsive structural flexibility.

The Distributions and Dependences of 3D Particle Morphology Characteristics for Crushed and Natural Sands by X-Ray uCT Investigations.

The morphology of an individual particulate refers to its shape characteristics and size properties, which both play important roles for granular matter in physics, mechanics, chemistry, and biology. In this study, ellipsoidality is defined as a 3D shape index for evaluating particle roundness, and an explicit calculation method is applied. The dependences of 3D shape characteristics (aspect ratios, sphericity, and ellipsoidal degree) on particle size (ranges from 0.

Classification of Chicken Carcass Breast Blood-Related Defects Using Hyperspectral Imaging Combined with Convolutional Neural Networks.

For chicken carcass breast blood-related defects (CBDs), which occur with high frequency, the visual features are approximated in terms of the similarity of the composition of these defects, making it challenging to classify them, either manually or automatically, using conventional machine vision. The aim of this paper was to introduce a method of CBD classification based on hyperspectral imaging combined with Convolutional Neural Networks (CNNs). To process hyperspectral data, the Improved Firefly Band Selection Algorithm was constructed with the 1-D CNN CBD classification model as the objective function, achieving a reduction in the dimensionality of hyperspectral data.

Wearable Temperature Sensor Enhanced Volatilomics Technique for Swift and Convenient Detection of Latrogenic Botulism.

Accurately assessing potential side effects following botulinum neurotoxin (BoNT) injection remains a formidable challenge. To address this issue, an innovative approach is developed that combines a wearable temperature sensor with a sophisticated volatilomics technique, aimed at facilitating the rapid and convenient prediction of potential physical discomfort related to latrogenic botulism. The investigation identifies five volatile organic compounds (VOCs)-acetone, styrene, ethanol, 2-pentanone, and n-butano-as promising markers indicative of BoNT poisoning.

General anesthesia induces acute cell-free DNA methylation changes in peripheral blood.

Background: Short-term and long-term adverse events could occur after general anesthesia (GA) and the specific mechanism driving these effects has not yet been well-characterized. In this study, we aimed to evaluate the global effect of GA on DNA methylation in the cell-free DNA (cfDNA) of surgical lung-nodule patients.

Methods: This large retrospective cohort study enrolled 1,006 surgical lung nodule patients (529 pre-anesthesia, and 477 post-anesthesia).

Comparative Proteomics and -Glycoproteomics Reveal the Effects of Different Plasma Protein Enrichment Technologies.

Human plasma proteomic and glycoproteomic analyses have emerged as an alternate avenue to identify disease biomarkers and therapeutic approaches. However, the vast number of high-abundance proteins in plasma can cause mass spectrometry (MS) suppression, which makes it challenging to detect low-abundance proteins (LAP). Currently, immunoaffinity-based depletion methods and strategies involving nanomaterial protein coronas have been developed to remove high-abundance proteins (HAP) and enhance the depth of plasma protein identification.

Willingness to Pay for Antiretroviral Drugs Covered by Medical Insurance among People Living with HIV in 18 Chinese Cities.

Objective: Antiretroviral drugs covered by medical insurance have been gradually used by people living with human immunodeficiency virus (PLWH) in recent years in China. This study aimed to analyze their willingness to pay (WTP) for antiretroviral drugs.

Methods: A mixed-methods study design involving a cross-sectional survey and in-depth interviews was conducted.

The ternary complex of Mn, synthetic decapeptide DP1 (DEHGTAVMLK), and orthophosphate is a superb antioxidant.

Mn coordinated by orthophosphate (Pi), metabolites, or peptides acts as a superoxide dismutase (SOD), and these Mn antioxidant complexes are universally accumulated in extremely radiation-resistant cell types across the tree of life. This behavior prompted design of decapeptide DP1 (DEHGTAVMLK) as a Mn ligand, and development of a highly potent Mn-antioxidant (MDP) containing [Pi] = 25 mM, and [DP1] = 3 mM, the ratio found in the radioresistant bacterium , with [Mn] = 1 mM. MDP is an exceptional antioxidant, both in vitro and in vivo, and has reinvigorated the development of radiation-inactivated whole-cell vaccines.

Gut microbiota/metabolites not only participate in the food and energy metabolism but also contribute to the host immune response and homeostasis. The alternation of gut microbiota/metabolites has been widely related to intestinal and extra-intestinal disorders such as intestinal bowel diseases (IBDs). Bactericidal substances from gut epithelial cells can regulate the composition of gut microbiota.

Non-immunoglobin scaffold binders as efficient affinity ligands for purification of broad-spectrum serum albumins.

Although non-immunoglobin scaffold binders with high affinity and broad spectrum for albumin are attractive for lab-scale albumin purification, affinity chromatography based on these binders has not been developed. Here, the albumin-binding capabilities of representative binders, including protein G-derived albumin binding domain (ABD), albumin binding nanofitins (ABNF), and human serum albumin affimer 31 (HSA31) were predicted by interaction structure analysis and verified by experimental assays. Interaction structure prediction suggested that ABD possessed great potential to bind human (HSA), rhesus monkey (RhSA), mouse (MSA), and rat serum albumin (RSA), whereas ABNF might only bind HSA and bovine serum albumin (BSA), and HSA31 might not bind any of the tested albumins.
