Evaluation of circadian rhythm and prognostic variability pre-and post-CEA or CAS treatment in patients with carotid artery stenosis.

Objective: Carotid artery stenosis, primarily caused by atherosclerosis, is a major risk factor for ischemic stroke. Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are established interventions to reduce stroke risk and restore cerebral blood flow. However, the effect of these treatments on circadian rhythms, and their influence on stroke recovery, remains underexplored.

Protein Coronation-Induced Cancer Staging-Dependent Multilevel Cytotoxicity: An All-Humanized Study in Blood Vessel Organoids.

The protein corona effect refers to the phenomenon wherein nanomaterials in the bloodstream are coated by serum proteins, yet how protein coronated nanomaterials interact with blood vessels and its toxicity implications remain poorly understood. In this study, we investigated protein corona-related vessel toxicity by using an all-humanized assay integrating blood vessel organoids and patient-derived serum. Initially, we screened various nanomaterials to discern how parameters including size, morphology, hydrophobicity, surface charge, and chirality-dependent protein corona difference influence their uptake by vessel organoids.

Concatemer-assisted stoichiometry analysis: targeted mass spectrometry for protein quantification.

Large multiprotein machines are central to many biological processes. However, stoichiometric determination of protein complex subunits in their native states presents a significant challenge. This study addresses the limitations of current tools in accuracy and precision by introducing concatemer-assisted stoichiometry analysis (CASA).

Effects of dimethylarsenate coprecipitation with ferrihydrite on Fe(II)-induced mineral transformation and the release of dimethylarsenate.

Organoarsenicals are toxic pollutants of global concern, and their environmental geochemical behavior might be greatly controlled by iron (Fe) (hydr)oxides through coprecipitation, which is rarely investigated. Here, the effects of the incorporation of dimethylarsenate (DMAs(V)), a typical organoarsenical, into the ferrihydrite (Fh) structure on the mineral physicochemical properties and Fe(II)-induced phase transformation of DMAs(V)-Fh coprecipitates with As/Fe molar ratios up to 0.0876 ± 0.

Response of ZmPHO1 family members to low phosphorus stress and association of natural variation in ZmPHO1;2a reveal the role of low phosphorus tolerance.

Phosphorus (Pi) is an essential nutrient for plants to sustain normal life processes. In this study, we found that the ZmPHO1 proteins had similar molecular weights and the same conserved domain. Phylogenetic and cis-acting element analysis showed that ZmPHO1s were divided into 4 subgroups, in which ZmPHO1;2a and ZmPHO1;2b were closely phylogenetic with OsPHO1;2b, and the promoter region of ZmPHO1s contained abundant abiotic stress-related elements.

LEF3 phosphorylation attenuates the replication of Bombyx mori nucleopolyhedrovirus by suppressing its interaction with alkaline nuclease.

Late expression factor 3 (LEF3), a multifunctional single-stranded DNA binding protein encoded by baculoviruses, is indispensable for viral DNA replication and plays a pivotal role in viral infection. Our previous quantitative analysis of phosphorylomics revealed that the phosphorylation levels of two serine residues (S8 and S25) located in LEF3 nuclear localization sequence were significantly up-regulated after Bombyx mori nucleopolyhedrovirus (BmNPV) infection, but the underlying mechanism remained unknown. To investigate the impact of phosphorylation on BmNPV infection, site-direct mutagenesis was performed on LEF3 to obtain phosphorylated mimic (S/D) or dephosphorylated mimic (S/A) mutants.

Lactoferrin-modified nanoemulsions enhance brain-targeting and therapeutic efficacy of arctigenin against Toxoplasma gondii-induced neuronal injury.

Toxoplasma gondii, a neurotropic protozoan parasite, affects the central nervous system and causes various neurological disorders. Previous studies have demonstrated that Arctigenin (AG) exhibits anti-T. gondii activity and reduces depression-like behaviors induced by T.

Effects of Peer Video Feedback Based on Cultural Historical Activity Theory in the Operational Training of New Nurses: A Quasi-Experimental Study.

Sodium ferulate attenuates ischaemic stroke by mediating the upregulation of thrombospondin-4 expression and combined treatment with bone marrow mesenchymal stem cells.

Ischaemic stroke is one of the major diseases affecting human health, involving complex and diverse pathological mechanisms, including inflammatory response, oxidative stress and angiogenesis. Sodium ferulate (SF) exerts a protective effect on cerebral ischaemia/reperfusion and when combined with bone marrow mesenchymal stem cells (BMSCs), has a considerable therapeutic effect on brain injury in rats. Here, we speculate that SF also exerts cerebroprotective effects.

The ability of virtual noncontrast images to remove intrinsic and external iodine from the thyroid via dual-layer spectral detector computed tomography.

Background: Virtual noncontrast (VNC) images generated by dual-layer spectral computed tomography (DLCT) remove iodine influence from enhanced images to simulate true noncontrast (TNC) images. Previous research has demonstrated the high comparability of abdominal VNC images with TNC images, suggesting their potential as substitutes. Given the thyroid's significant iodine content, this study evaluated the efficacy of VNC images for removing both intrinsic and extrinsic iodine through an analysis of computed tomography (CT) attenuation and iodine density in TNC and enhanced VNC thyroid images.

Effects of Fermented Soybean Hulls on Reproductive Performance, Blood Physiology and Immune Parameters Along with Fecal Microbiota in Sows.

This study aims to investigate the effects of fermented soybean hulls (FSHS) on reproductive performance, plasma biochemical profiles, immune parameters, and fecal microbiota in sows. A total of 325 sows were randomized into five groups, each fed a diet with varying FSHS proportions: 0% (control), 2% (FSHS2), 4% (FSHS4), 6% (FSHS6), and 8% (FSHS8). Diets were prepared by replacing conventional soybean hulls with FSHS in equal amounts.

Molten salt-assisted synthesis of boron-doped carbon nitride for photocatalytic hydrogen evolution.

In this work, B and K were introduced into the heptazine structure of carbon nitride to synthesize the catalyst kalium-boron doped carbon nitride (KBCN) with a larger light absorption range and improved photogenerated carrier separation rate. Boron atoms are introduced into the carbon nitride heptazine units to optimize the electronic structure within the carbon nitride planes, and the B-N bonds formed by the heptazine units facilitate charge transfer. Potassium atoms are introduced into the carbon nitride interlayer as charge transfer channels to synergistically promote the transfer of photogenerated electrons.

High-Throughput Search for Photostrictive Materials Based on a Thermodynamic Descriptor.

Photostriction is a phenomenon that can potentially improve the precision of light-driven actuation, the sensitivity of photodetection, and the efficiency of optical energy harvesting. However, known materials with significant photostriction are limited, and effective guidelines to discover new photostrictive materials are lacking. In this study, we perform a high-throughput computational search for new photostrictive materials based on simple thermodynamic descriptors, namely, the band gap pressure and stress coefficients.
