Mannose Promotes β-Amyloid Pathology by Regulating BACE1 Glycosylation in Alzheimer's Disease.

Hyperglycemia accelerates Alzheimer's disease (AD) progression, yet the role of monosaccharides remains unclear. Here, it is demonstrated that mannose, a hexose, closely correlates with the pathological characteristics of AD, as confirmed by measuring mannose levels in the brains and serum of AD mice, as well as in the serum of AD patients. AD mice are given mannose by intra-cerebroventricular injection (ICV) or in drinking water to investigate the effects of mannose on cognition and AD pathological progression.

SchNet_IIA: Potential Energy Surface Fitting by Interatomic Interactions Attention Based on Transfer Learning Analysis.

Machine learning methods for fitting potential energy surfaces and molecular dynamics simulations are becoming increasingly popular due to their potentially high accuracy and savings in computational resources. However, existing application models often rely on basic architectures like artificial neural networks (ANNs) and multilayer perceptron (MLP), lagging behind cutting-edge technologies in the machine learning domain. Furthermore, the complexity of current machine learning frameworks leads to reduced interpretability and challenges for improvement.

Single-Nucleus and Spatial Transcriptome Profiling Delineates the Multicellular Ecosystem in Hepatocellular Carcinoma After Hepatic Arterial Infusion Chemotherapy.

Hepatic arterial infusion chemotherapy (HAIC) has emerged as a promising treatment strategy for hepatocellular carcinoma (HCC), but a detailed understanding of the multicellular ecosystem after HAIC treatment is lacking. Here, we collected tumor samples from treatment-naïve primary and post-HAIC HCC, and integrated single-nucleus RNA sequencing with spatial transcriptomics to characterize the tumor ecosystem in the post-HAIC HCC. Increased fractions and enhanced cellular communication of CD4 T, CD20 B, and dendritic cell subtypes were identified in post-HAIC tumors.

Cost-Effective, Hydrogen-Rich, and Ultramicroporous Metal-Organic Framework for Efficient Separation of SF from N.

It is essential for the industry to create an adsorbent that combines a high capacity with selectivity to achieve the effective separation of SF from gas mixtures. In this study, we prepared a cost-effective nickel-based metal-organic framework (MOF), Ni(BTC)(BPY), which features hydrogen-rich ultramicroporous channels specifically designed for separating SF/N gas mixtures. The findings from the adsorption experiments demonstrated that Ni(BTC)(BPY) achieved a remarkable SF adsorption capacity of 5.

Diagnostic role of the neutrophil‑to‑lymphocyte ratio and the platelet‑to‑lymphocyte ratio in breast cancer: A systematic review and meta‑analysis.

Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) may be indicative of breast cancer (BC); however, this remains inconclusive. With the aim to assess the current literature to evaluate the diagnostic roles of NLR PLR and LMR in BC, a systematic literature search was performed using the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, VIP database and China Biology Medicine disc databases up to August 29, 2023. The standardized mean deviation and 95% confidence intervals (CI) for each outcome was reported, and heterogeneity and publication bias were assessed.

Discovering SnB: a half-sandwich structure with double aromaticity and pathways to molecular machines.

Numerous boron-based molecular fluxional models, such as the Wankel motor, tank treads B and BC, and the Earth-Moon system BeB, have been widely recognized for their potential to develop molecular machines. From a series of tin-doped boron clusters SnB ( = 5-14), the half-sandwich structure SnB is found to possess high relative energy stability, and a HOMO-LUMO gap of 4.33 eV.

Extracellular vesicles derived from mesenchymal stem cells suppress breast cancer progression by inhibiting angiogenesis.

Previous studies have highlighted the antitumor effects of mesenchymal stem cell‑derived extracellular vesicles (MSC‑EVs), positioning them as a promising therapeutic avenue for cancer treatment. However, some researchers have proposed a bidirectional influence of MSC‑EVs on tumors, determined by the specific tissue origin of the MSCs and the types of tumors involved. The present study aimed to elucidate the effects of human placenta MSC‑derived extracellular vesicles (hPMSC‑EVs) on the malignant behavior of a mouse breast cancer model of 4T1 cells and .

Isolation and Characterization of a Novel Phage against Belonging to a New Genus.

causes substantial economic losses in the aquaculture industry. With the rise of multidrug-resistant strains, phages present a promising solution. Here, a novel lytic phage, vB_ValC_RH2G (RH2G), that efficiently infects the pathogenic strain ATCC 17749, was isolated from mixed wastewater from an aquatic market in Xiamen, China.

Electronic Structure, Aromaticity, and Magnetism of Minimum-Sized Regular Dodecahedral Endohedral Metallofullerenes Encapsulating Rare Earth Atoms.

A series of minimally sized regular dodecahedron-embedded metallofullerene REC clusters (RE = Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, and Gd) as basic units of nanoassembled materials with tunable magnetism and UV sensitivity have been explored using density functional theory (DFT). The contribution of the 4f orbital of the rare earth atom at the center of the C cage to the frontier molecular orbital of REC gives the REC cluster additional stability. The AdNDP orbitals of the four REC superatoms that conform to the spherical jellium model indicate that through natural population analysis and spin density diagrams, we observe a monotonic increase in the magnetic moment from Ce to Gd.

The high electron mobility for spin-down channel of two-dimensional spin-polarized half-metallic ferromagnetic EuSiN monolayer.

The two-dimensional (2D) monolayer material MoSiN was successfully synthesized in 2020[Hong et al., Science 369, 670, (2020)], exhibiting a plethora of new phenomena and unusual properties, with good stability at room temperature.
