Alzheimer's disease risk ABCA7 p.A696S variant disturbs the microglial response to amyloid pathology in mice.

The adenosine triphosphate-binding cassette transporter A7 (ABCA7) gene is ranked as one of the top susceptibility loci for Alzheimer's disease (AD). While ABCA7 mediates lipid transport across cellular membranes, ABCA7 loss of function has been shown to exacerbate amyloid-β (Aβ) pathology and compromise microglial function. Our family-based study uncovered an extremely rare ABCA7 p.

Effect of NaCl stress germination on microstructure and physicochemical properties of wheat starch.

Germination can enhance the nutritional properties of wheat and improve its bioavailability, while simultaneously altering the microstructure of wheat starch, which further impacts its physicochemical characteristics. This work investigated the synergistic effects of germination and NaCl on the microstructure and physicochemical properties of wheat starch by applying a 60 mmol/L NaCl solution. The results indicated that germination significantly influenced both the chemical composition and microstructure of wheat starch, as evidenced by cracks and pores, variations in size, crystallinity, lamellar order, hydrogen bond disruption, branching degree, and molecular weight distribution.

Survival and early outcomes following lung transplantation for interstitial lung disease associated with non-scleroderma connective tissue disease: a national cohort study.

Objectives: The progressive decline in interstitial lung disease associated with non-scleroderma connective tissue disease (ILD-NSCTD) is linked to poor prognosis and frequently results in respiratory failure. Lung transplantation (LTx) offers a viable treatment option, yet its outcomes in ILD-NSCTD remain contentious, particularly across different subtypes.

Methods: This retrospective cohort study included patients with idiopathic pulmonary fibrosis (IPF) (n=11,610) and ILD-NSCTD (n=610) listed in the United Network for Organ Sharing (UNOS) database who underwent lung transplantation between May 5, 2005, and December 31, 2022.

The Multiple Roles of Na Ions in Highly Efficient CZTSSe Solar Cells.

Sodium (Na) doping is a well-established technique employed in chalcopyrite and kesterite solar cells. While various improvements can be achieved in crystalline quality, electrical properties, or defect passivation of the absorber materials by incorporating Na, a comprehensive demonstration of the desired Na distribution in CZTSSe is still lacking. Herein, a straightforward Na doping approach by dissolving NaCl into the CZTS precursor solution is proposed.

Association of cancer information seeking behavior with cigarette smoking and E-cigarette use among U.S. adults by education attainment level: A multi-year cross-sectional analysis from a nationally representative sample in 2017-2020.

A multi-year cross-sectional analysis using a pooled data of the Health Information National Trends Survey 5, Cycles 1-4 (2017-2020) was conducted. To examine the association of cancer information seeking behavior with current cigarette smoking (currently smoke every day/some days among individuals who smoked 100+ cigarettes in lifetime) and e-cigarette use (currently use every day/some days among lifetime users) in nationally representative U.

Tailoring particle size of PbI towards efficient perovskite solar cells under ambient air conditions.

PbI films as templates are essential to the quality of perovskite (PVK) film in a two-step sequential deposition process. Herein, we demonstrate that PbI microcrystal powder (P-PbI) of micrometer size is beneficial for preparing higher-quality PbI films in contrast to millimeter-sized PbI crystals (C-PbI) under low relative humidity (RH) conditions. Surprisingly, C-PbI allowed the growth of denser films than P-PbI under heavy RH conditions.

Multifunctional porous poly (L-lactic acid) nanofiber membranes with enhanced anti-inflammation, angiogenesis and antibacterial properties for diabetic wound healing.

With increased diabetes incidence, diabetic wound healing is one of the most common diabetes complications and is characterized by easy infection, chronic inflammation, and reduced vascularization. To address these issues, biomaterials with multifunctional antibacterial, immunomodulatory, and angiogenic properties must be developed to improve overall diabetic wound healing for patients. In our study, we prepared porous poly (L-lactic acid) (PLA) nanofiber membranes using electrospinning and solvent evaporation methods.

MicroRNA-128 suppresses tau phosphorylation and reduces amyloid-beta accumulation by inhibiting the expression of GSK3β, APPBP2, and mTOR in Alzheimer's disease.

Introduction And Aims: Alzheimer's disease (AD) is characterized by the abnormal accumulation of hyperphosphorylated tau proteins and amyloid-beta (Aβ) peptides. Recent studies have shown that many microRNAs (miRNAs) are dysregulated in AD, and modulation of these miRNAs can influence the development of tau and Aβ pathology. The brain-specific miRNA miR-128, encoded by MIR128-1 and MIR128-2, is important for brain development and dysregulated in AD.

Pine Dendritic Bi/BiOBr Photocatalyst for Efficient Degradation of Antibiotics.

Constructing Bi/BiO ( = Cl, Br) heterostructures with unique electron transfer channels enables charge carriers to transfer unidirectionally at the metal/semiconductor junction and inhibits the backflow of photogenerated carriers. Herein, novel pine dendritic Bi/BiO ( = Cl, Br) nanoassemblies with multiple electron transfer channels have been successfully synthesized with the assistance of l-cysteine (l-Cys) through a one-step solvothermal method. Such a pine dendritic Bi/BiOBr photocatalyst shows excellent activity toward the degradation of many antibiotics such as tetracycline (TC), norfloxacin, and ciprofloxacin.

Immunomodulation of MiRNA-223-based nanoplatform for targeted therapy in retinopathy of prematurity.

Retinopathy of prematurity (ROP) is characterized by pathological angiogenesis and associated inflammation in the retina and is the leading cause of childhood blindness. MiRNA-223 (miR-223) drives microglial polarization toward the anti-inflammatory phenotype and offers a therapeutic approach to suppress inflammation and consequently pathological neovascularization. However, miRNA-based therapy is hindered by the low stability and non-specific cell-targeting ability of delivery systems.

Exploration of the strategies to enhance the regeneration of the optic nerve.

In adult mammals, only minimal regeneration of the optic nerve (ON) is possible. Both the low levels of intrinsic regeneration ability of retinal ganglion cells (RGCs) and the inhibitory glial environment of ON contribute to it. To explore the influence of these two factors on the extent of axon regeneration, two ON injury models were established.

Long-term induction of endogenous BMPs growth factor from antibacterial dual network hydrogels for fast large bone defect repair.

Osteoinductive, osteoconductive, and antibacterial properties of bone repair materials play important roles in regulating the successful bone regeneration. In the present work, we developed pH-sensitive gelatin methacryloyl (GelMA)-oxidized sodium alginate (OSA) hydrogels for dual-release of gentamicin sulfate (GS) and phenamil (Phe) to enhance the antibacterial activity and to promote large bone defect repair. Controlled release of GS was achieved through physical blending with GelMA-OSA solution before photo-polymeriaztion, while Phe was encapsulated into mesoporous silicate nanoparticles (MSN) within the hydrogels.

Spatial and temporal super-resolution for fluorescence microscopy by a recurrent neural network.

A novel spatial and temporal super-resolution (SR) framework based on a recurrent neural network (RNN) is demonstrated. In this work, we learn the complex yet useful features from the temporal data by taking advantage of structural characteristics of RNN and a skip connection. The usage of supervision mechanism is not only making full use of the intermediate output of each recurrent layer to recover the final output, but also alleviating vanishing/exploding gradients during the back-propagation.

Hypoxia-mimicking 3D bioglass-nanoclay scaffolds promote endogenous bone regeneration.

Large bone defect repair requires biomaterials that promote angiogenesis and osteogenesis. In present work, a nanoclay (Laponite, XLS)-functionalized 3D bioglass (BG) scaffold with hypoxia mimicking property was prepared by foam replication coupled with UV photopolymerization methods. Our data revealed that the incorporation of XLS can significantly promote the mechanical property of the scaffold and the osteogenic differentiation of human adipose mesenchymal stem cells (ADSCs) compared to the properties of the neat BG scaffold.
