Proteolysis-targeting chimeras (PROTACs) is regarded as an emerging therapeutic strategy with unlimited potential because of its mechanism of inducing target protein degradation though harnessing ubiquitin-proteasome system (UPS). Recently, researchers are combining the advantages of PROTACs and dual-targeted drugs to explore some new types of dual PROTACs degraders. The utilization of dual PROTACs not only enhances the efficiency of selective degradation for two or more distinct proteins, but also facilitates synergistic interactions between target proteins to optimize therapeutic efficacy as well as overcome resistance.

Natural products from marine microorganisms are becoming the hotspots in discovery of new candidate drug entities, especially in the area of cancer. Brefeldin A (BFA) is a natural Arf-GEFs inhibitor, but due to the low aqueous solubility, strong toxicity, and poor bioavailability, it is urgent to conduct structural optimization research.
View Article and Find Full Text PDFFerrous ion accumulation and lethal oxidative stress mediate irreversible retinal pigment epithelial (RPE) cell ferroptosis and subsequent photoreceptor degeneration, a potential key pathogenic factor in the onset of dry age-related macular degeneration (dAMD), causing irreversible vision loss in the global elderly population. However, currently, no effective interventional treatment strategy exists in clinical practice. Herein, lesion site-targeted melanin-like nanoparticles, named ConA-MelNPs, are designed as a novel ferroptosis inhibitor for retinal degenerative diseases.

Behind the drastic springing-up of MTI programs during the decade, MTI teachers' professional development draws the attention of MTI administrators and researchers. This study adopted a mixed-method of a large-scale survey among 514 MTI teachers across China and a qualitative interview study of seven participants and discussed MTI teachers' perceptions of dilemmas and inner-world needs in their professional development.

Excitotoxicity is one of the most important mechanisms involved in the pathophysiological process of depression. In our previous studies, n-butanol extract from maize roots was found to have good neuroprotective effects due to its antioxidative activity.

Objective: To compare the effectiveness of sequential method pure single-port lumpectomy-breast conserving surgery (SMPSL-BCS) in treating early-stage breast cancer patients with tumors in different quadrants.
Methods: A retrospective analysis was conducted on 200 early-stage breast cancer female patients admitted between January 2023 and December 2023. According to the quadrant where the tumor was located, the patients were allocated into the upper outer quadrant group (UO group), lower outer quadrant group (LO group), upper inner quadrant group (UI group), and lower inner quadrant group (LI group), with 50 cases in each group.
Rationale And Objectives: The aim of this study was to develop and validate a nomogram for predicting emergent conversion to general anaesthesia (GA) in stroke patients during thrombectomy.
Methods: In this retrospective study, 458 patients (320 and 138 were randomised into the training and validation cohorts) were enroled. Univariable and multivariable logistic regression analyses were employed to identify risk factors for emergent conversion to GA.
Singer (PCS) has attracted increasing attention as a raw material for medicine and food. Its quality is greatly affected by the accumulation of metabolites, which varies with the applied drying methods. In this study, we utilize an approach based on ultra-high-performance liquid chromatography/Q Exactive mass spectrometry (UHPLC-QE-MS) to reveal the metabolic profiles of PCS from three different drying methods (natural air-drying, NAD; hot-air-drying, HAD; vacuum freeze-drying, VFD).

In response to the growing threat of bacterial infections and the escalating resistance to conventional antibiotics, this research introduces a novel injectable, self-healing antimicrobial hydrogel comprising bioactive aldolized hyaluronic acid (AHA) and quaternized chitosan (QCS). This designed QCS/AHA hydrogel incorporates self-assembling peptide nanofibers (PNFs) and small-sized silver nanoparticles (AgNPs) for tailored functionality.

Assessing the causal relationship between modifiable entertainment activity factors and the risk of Alzheimer's disease is important for developing public health measures, but establishing causal relationships in epidemiological data may be challenging.
Methods: This study using the two-sample Mendelian randomization analysis aimed to investigate the causal effect of entertainment activity factors on the risk of Alzheimer's disease.
Currently, the clinical outcomes of peripheral nerve injuries are suboptimal, highlighting the urgent need to understand the mechanisms of nerve injury to enhance treatment strategies. Muscle-derived stem cells (MDSCs) are a diverse group of multipotent cells that hold promise for peripheral nerve regeneration due to their strong antioxidant and regenerative properties. Our research has revealed that severe ferroptosis occurs in the sciatic nerve and ipsilateral dorsal root ganglion following sciatic nerve injury.

Despite clinical evidence suggesting the antipruritic effects of bright light treatment, the circuit mechanisms underlying the effects of light on itch-related behaviors remain poorly understood. In this study, we demonstrate that bright light treatment reduces itch-related behaviors in mice through a visual circuit related to the lateral parabrachial nucleus (LPBN).

A novel functional polycarbonate (PAGC), characterized by the presence of double bonds within its side chain, was successfully synthesized through a ternary copolymerization of propylene oxide (PO), allyl glycidyl ether (AGE), and carbon dioxide (CO). Polyhedral oligomeric silsesquioxanes octamercaptopropyl (POSS-SH) was employed as a crosslinking agent, contributing to the formation of organic-inorganic hybrid materials. This incorporation was facilitated through thiol-ene click reactions, enabling effective interactions between the POSS molecules and the double bonds in the side chains of the polycarbonate.
