Dynamic Detection of the E3-PROTAC-Target Protein Ternary Complex and Bimolecular Fluorescence Complementation.

Proteolysis-targeting chimeras (PROTACs) have played an important role in the development of protein-targeted degradation drugs. However, effective tools are urgently required for the further development and validation of PROTACs. We developed a high-potency reporter (AKT-PROTAC-Reporter; APR) for PROTACs that specifically targets AKT.

Astragalus polysaccharides alleviate DSS-induced ulcerative colitis in mice by restoring SCFA production and regulating Th17/Treg cell homeostasis in a microbiota-dependent manner.

Natural polysaccharides from Astragalus membranaceus have been shown to relieve ulcerative colitis (UC). However, the mechanism and causal relationship between the gut microbiota and Astragalus polysaccharides (APS) treatment of UC are unclear. The results of the present study showed that APS ameliorated colonic injury and the disruption of the gut microbiota and restored intestinal immune homeostasis in mice with DSS-induced colitis.

The effect of vitamin D2 on lipid profile, anthropometric indices, blood pressure, and inflammatory and glycemic biomarkers in humans: A systematic review and meta-analysis of randomized controlled trials.

Background And Aim: Even though the role of D2 (ergocalciferol) on cardiovascular disease risk components has been studied, conflicting results have been reported. Moreover, no single study has studied all these parameters and the role of vitamin D2 individually has not been assessed; hence, this systematic review and meta-analysis of randomized controlled trials was conducted to assess the effect of vitamin D2 supplementation on lipid profile, anthropometric indices, blood pressure, and inflammatory and glycemic biomarkers in humans.

Methods: Web of Science, Scopus, PubMed/Medline, and Embase were searched from database inception to July 2024, and the random effects model, according to the DerSimonian and Laird method, was used to generate combined estimates of the intervention's effect on the outcomes.

Endosome-microautophagy targeting chimera (eMIATAC) for targeted proteins degradation and enhance CAR-T cell anti-tumor therapy.

Since oncogene expression products often exhibit upregulation or abnormally activated activity, developing a technique to regulate abnormal protein levels represent a viable approach for treating tumors and protein abnormality-related diseases. We first screened out eMIATAC components with high targeted degradation efficiency and explored the mechanism by which eMIATAC induced target protein degradation, and verified the degradation efficiency of the target protein by protein imprinting and flow cytometry. Next, we recombined eMIATAC with some controllable elements to verify the regulatable degradation performance of the target protein.

Cross-contamination and ecological risk assessment of antibiotics between rivers and surrounding open aquaculture ponds.

Antibiotics are causing widespread concern as one of the emerging contaminants. There is the abuse of antibiotics in high-density open aquaculture, and the tailwater is often discharged into surrounding rivers. At the same time, the water replenishment of open aquaculture ponds from nearby rivers containing antibiotic contamination from different sources may result in cross-contamination.

Fluid Multivalent Recognition Accelerating and Boosting Upconversion Luminescence-Activated DNA Nanomachines for Rapid and Sensitive Imaging.

By integrating near-infrared (NIR) light-dependent optical control and DNA walkers-based signal amplification, upconversion luminescence-activated DNA nanomachines hold great potential in conducting an analysis. For the typical DNA nanomachines, the immobile multivalent recognition interface greatly compromised the reaction kinetics and amplification efficiency due to the cleavage-dependent response mode. In this work, novel upconversion luminescence-activated DNA nanomachines with a fluid multivalent recognition interface were reported for rapid and sensitive imaging.

Impact analysis of hydraulic loading rate and antibiotics on hybrid constructed wetland systems: Insight into the response to decontamination performance and environmental-associated microbiota.

Hybrid constructed wetlands (HCWs) are a promising solution for water ecology and environmental treatment, not only for conventional types of water pollution but also for antibiotics. Among the critical parameters for wetlands, the hydraulic loading rate (HLR) is especially important given the challenges of antibiotics treatment and frequent extreme rainfall. To investigate the removal performance of different HLRs on nutrients and antibiotics, as well as the response of antibiotics to nutrient removal, and the impact of HLRs on microbial communities, new HCWs with vertical flow constructed wetlands (VFCWs) and floating constructed wetlands (FCWs) in series were built.

Association between IL10 rs1800896 polymorphism and risk of pediatric asthma: A meta-analysis.

Introduction: Asthma is a common chronic condition in children. Several studies have explored the potential association between IL10 rs1800896 polymorphism and the risk of asthma in children, but the findings have been inconsistent. To address these discrepancies, we conducted a systematic review and meta-analysis to assess the relationship between IL10 rs1800896 polymorphisms and the susceptibility to pediatric asthma.

Association between SCN1A polymorphism and risk of epilepsy in children: A systematic review and meta-analysis.

Epilepsy is a common neurological disorder in children. Numerous studies have demonstrated the association between SCN1A polymorphisms and risk of epilepsy in adults, but their role in epilepsy in children has just gained traction and results have remained inconsistent. In this work, we performed a systematic review and meta-analysis to assess the association between SCN1A polymorphisms and risk for epilepsy in children.

miR-5581 Contributes to Osteoarthritis by Targeting NRF1 to Disturb the Proliferation and Functions of Chondrocytes.

Antibody-based binding domain fused to TCRγ chain facilitates T cell cytotoxicity for potent anti-tumor response.

Chimeric antigen receptor T-cell (CAR-T) therapy has demonstrated potent clinical efficacy in the treatment of hematopoietic malignancies. However, the application of CAR-T in solid tumors has been limited due in part to the expression of inhibitory molecules in the tumor microenvironment, leading to T-cell exhaustion. To overcome this limitation, we have developed a synthetic T-cell receptor (TCR) that targets programmed death-ligand 1 (PD-L1), a molecule that is widely expressed in various solid tumors and plays a pivotal role in T-cell exhaustion.

Shear Adhesion of Ice on Large-Sized Grooved Aluminum Surfaces.

Ice adhesion is important when designing aircraft anti-icing/de-icing systems. Major and minor grooves are common in the skin of aircraft. However, the effects of millimeter-scale grooves on ice adhesive strength have not been given due attention.

Formation Mechanisms of Nitro Products from Transformation of Aliphatic Amines by UV/Chlorine Treatment.

Formation of nitrogenous disinfection byproducts from aliphatic amines is a widespread concern owing to the serious health risks associated with them. However, the mechanisms of transforming aliphatic amines and forming nitro products in the UV/chlorine process have rarely been discussed, which are investigated in this work. Initially, secondary amines (RRNH) are transformed into secondary organic chloramines (RRNCl) via chlorination.

Hypouricemic Actions of the Pericarp of Mangosteen and .

However, available drugs for hyperuricemia in the clinic are limited. Recently, a lot of research has been conducted in order to discover new uric acid-lowering agents from plants and foods.

(±)-Zanthonitidumines A and B: Two new benzophenanthridine alkaloids enantiomers from Zanthoxylum nitidum and their anti-inflammatory activity.

Two new benzophenanthridine alkaloids enantiomers (±)-zanthonitidumines A (1) and B (2), along with seven known analogues (3-9), were isolated from Zanthoxylum nitidium.

Compound 2 exhibited the most significant inhibition of IL-6 generation as well as TNF-α release which suggest that it may be a potential anti-inflammatory agent.

Occurrence, source tracking and removal of antibiotics in recirculating aquaculture systems (RAS) in southern China.

The recirculating aquaculture system (RAS) has attracted much attention in China as a way to rapidly transform and upgrade aquaculture ponds to realize zero-emissions of pollutants in aquaculture tail water. Tail water purification ponds (TWPPs) play an important role in the treatment of aquaculture wastewater. However, until now, there have been few reports on the occurrence of antibiotics in RAS and the removal of antibiotics from the TWPPs of RAS.
