To overcome the drawbacks of radiotherapy alone, it is also crucial to design a multifunctional radiosensitizer that simultaneously realizes multimodal treatment and tumor microenvironment modulation. Herein, a multifunctional radiosensitizer based on the CuBiS-BP@PEI nanoheterostructure (NHS) for multimodal cancer treatment is designed.

From Mechanisms to Medicine: Neurovascular Coupling in the Diagnosis and Treatment of Cerebrovascular Disorders: A Narrative Review.

Neurovascular coupling (NVC) refers to the process of local changes in cerebral blood flow (CBF) after neuronal activity, which ensures the timely and adequate supply of oxygen, glucose, and substrates to the active regions of the brain. Recent clinical imaging and experimental technology advancements have deepened our understanding of the cellular mechanisms underlying NVC. Pathological conditions such as stroke, subarachnoid hemorrhage, cerebral small vascular disease, and vascular cognitive impairment can disrupt NVC even before clinical symptoms appear.

We previously developed a strategy to recover rotavirus vaccine strain LLR from 11 cloned plasmids. Here, we report an improved reverse genetics system for LLR by combining two or three transcriptional cassettes in a single plasmid, which substantially enhances rescue efficiency from 66.

Photoexcited CuO/TiO Heterojunction for Photoelectrochemical Sensors for Nonenzymatic Glucose Detection.

Photoelectrochemical sensors have been studied for glucose detection because of their ability to minimize background noise and unwanted reactions. Titanium dioxide (TiO), a highly efficient material in converting light into electricity, cannot utilize visible light. In this regard, we developed a nonenzymatic glucose sensor by using a simple one-step electrospinning technique to combine cupric oxide with TiO to create a heterojunction.

PO Tetrahedron Assisted Chelate Engineering for 10.67%-Efficient Antimony Selenosulfide Solar Cells.

Anisotropic carrier transport and deep-level defect of antimony selenosulfide (Sb(S,Se)) absorber are two vital auses restraining the photovoltaic performance of this emerging thin-film solar cell. Herein, chelate engineering is proposed to prepare high-quality Sb(S,Se) film based on hydrothermal deposition approach, which realizes desirable carrier transport and passivated defects by using tetrahedral PO ion in dibasic sodium phosphate (NaHPO, DSP). The PO Lewis structure, on one hand in the form of [(SbO)(PO)] chelate, can adsorb on the polar planes of cadmium sulfide (CdS) layer, promoting the heterogeneous nucleation, and on the other hand, the tetrahedral PO inhibits horizontal growth of (SbS(e)) ribbons due to size effects, thus achieving desirable [hk1] orientation.

Commercial SiO Encapsulated in Hybrid Bilayer Conductive Skeleton as Stable Anode Coupling Chemical Prelithiation for Lithium-Ion Batteries.

Although Silicon monoxide (SiO) is regarded as the most promising next-generation anode material, the large volume expansion, poor conductivity, and low initial Coulombic efficiency (ICE) severely hamper its commercialization application. Designing a multilayer conductive skeleton combined with advanced prelithiation technology is considered an effective approach to address these problems. Herein, a reliable strategy is proposed that utilizes MXene and carbon nanotube (CNT) as dual-conductive skeletons to encapsulate SiO through simple electrostatic interaction for high-performance anodes in LIBs, while also performing chemical prelithiation.

Assessing the impact of evolocumab on thin-cap fibroatheroma and endothelial function in patients with very high-risk atherosclerotic cardiovascular disease: a study protocol for a randomized controlled trial.

Background: The prevalence of very high-risk atherosclerotic cardiovascular disease (ASCVD) is significant in China, with suboptimal rates of low-density lipoprotein cholesterol (LDL-C) compliance exacerbating plaque instability and causing a higher incidence of major adverse cardiac events (MACEs). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are effective in reducing LDL-C levels, increase the stability of vulnerable plaque, and influence the progression of atherosclerosis through multiple mechanisms as demonstrated in animal studies. However, there is currently a lack of evidence regarding the efficacy and safety of high-intensity statin therapy combined with PCSK9i in the secondary prevention of ASCVD in the Chinese population.

Aberrant neural event segmentation during a continuous social narrative in trauma-exposed older adolescents and young adults.

Post-traumatic stress and major depressive disorders are associated with "overgeneral" autobiographical memory, or impaired recall of specific life events. Interpersonal trauma exposure, a risk factor for both conditions, may influence how symptomatic trauma-exposed (TE) individuals segment everyday events. The ability to parse experience into units (event segmentation) supports memory.

Chemically engineered antibodies for autophagy-based receptor degradation.

Cell surface receptor-targeted protein degraders hold promise for drug discovery. However, their application is restricted because of the complexity of creating bifunctional degraders and the reliance on specific lysosome-shuttling receptors or E3 ubiquitin ligases. To address these limitations, we developed an autophagy-based plasma membrane protein degradation platform, which we term AUTABs (autophagy-inducing antibodies).
