Research Progress on Oil-Water Separation Materials Based on Polyurethane Modification.

Numerous oil-water mixtures produced through industrial production processes and daily activities pollute the ecological environment and pose risks to human health. The development of materials with high oil-water mixture separation efficiency can promote the recycling of oil and water resources and effectively prevent environmental pollution caused by their direct discharge. Most of the current oil-water separation materials consist of foam, aerogel, and other porous materials.

An alternative choice for overweight pediatric patient with femoral shaft fracture when rigid nail is contraindicated due to narrow intramedullary canal: Elastic stable intramedullary nail plus temporary external fixator.

Background: Length unstable femoral shaft fractures in school-aged children usually demand surgical treatment, but the optimal choice remains controversial, especially in overweight adolescents. This study aimed to compare the clinical results of locking compression plates (LCP) and elastic stable intramedullary nails (ESIN) combined with temporary external fixator (TEF) in school-aged children weighing over 50 kg.

Methods: Between January 2010 and January 2018, children over 50 kg with length unstable femoral shaft fracture treated with ESIN & EF in the authors' institute were included in this study.

Polymorphisms in the gene and neuroblastoma risk in Chinese children from Jiangsu province.

Neuroblastoma is the most prevalent extracranial solid tumor among children and exhibits remarkable heterogeneity. The methylation of cytosine to form 5-methylcytosine (m5C) is the primary type of modification found in DNA and RNA. The NOL1/NOP2/sun (NSUN) family, specifically NSUN1, is responsible for the methylation process and has been shown to play a key role in cell differentiation and cancer development.

The study of halogen effect on the reactivity of the serine-targeting covalent warheads.

Halogens favorably contributes to the drug potency and metabolic stability via electrostatic interactions. Herein, the halogen effects on the reactivity of the halogenated 2,2,2-trifluoroacetophenones as serine-targeting covalent warheads were investigated. Our results showed that introducing halogen atoms, especially Cl or Br, into the phenyl scaffold would influence the electron density around the ring, which led to different time-dependent inhibition response to the target serine hydrolase (hCES1A).

Efferocytosis: the resolution of inflammation in cardiovascular and cerebrovascular disease.

Cardiovascular and cerebrovascular diseases have surpassed cancer as significant global health challenges, which mainly include atherosclerosis, myocardial infarction, hemorrhagic stroke and ischemia stroke. The inflammatory response immediately following these diseases profoundly impacts patient prognosis and recovery. Efficient resolution of inflammation is crucial not only for halting the inflammatory process but also for restoring tissue homeostasis.

Comprehensive exploration of isocitrate dehydrogenase (IDH) mutations: Tumorigenesis, drug discovery, and covalent inhibitor advances.

Isocitrate dehydrogenase (IDH) is an enzyme that catalyses the oxidative decarboxylation of isocitrate, producing α-ketoglutarate (α-KG) relative to the hydroxylation of substrates. However, IDH mutants can further reduce α-KG to 2-hydroxyglutarate (2-HG) which competitively inhibits α-KG dependent enzymes, leading to the downregulation of normal hydroxylation pathways. Good IDH mutant inhibitors can effectively reduce the level of 2-HG and therefore disturb cellular malignant transformation.

Classic Vocal Performance Training Through C-VaC Method: Study of Core Muscle Stability Warm-Up Techniques via Computer-Aided Analysis.

Vocal warm-up is essential for achieving optimal vocal performance; however, traditional methods often neglect the role of core muscle stability. This study presents the Combined Vocal and Core Muscle Stability Warm-Up Method (C-VaC), which integrates core stability training with vocal exercises to improve vocal performance. The effectiveness of the C-VaC method was assessed among soprano majors at various stages using computer-assisted audio analysis for objective measurement.

Electrocatalytic conversion of nitrate to ammonia on the oxygen vacancy engineering of zinc oxide for nitrogen recovery from nitrate-polluted surface water.

Nitrate pollution in surface water poses a significant threat to drinking water safety. The integration of electrocatalytic reduction reaction of nitrate (NORR) to ammonia with ammonia collection processes offers a sustainable approach to nitrogen recovery from nitrate-polluted surface water. However, the low catalytic activity of existing catalysts has resulted in excessive energy consumption for NORR.

SREBP1 induction mediates long-term statins therapy related myocardial lipid peroxidation and lipid deposition in TIIDM mice.

Statins therapy is efficacious in diminishing the risk of major cardiovascular events in diabetic patients. However, our research has uncovered a correlation between the prolonged administration of statins and an elevated risk of myocardial dysfunction in patients with type II diabetes mellitus (TIIDM). Here, we report the induction of sterol regulatory element-binding protein 1 (SREBP1) activation, associated lipid peroxidation, and the consequent diabetic myocardial dysfunction after statin treatment and explored the underlying mechanisms.

Targeted protein degradation via cellular trafficking of nanoparticles.

Strategies that selectively bind proteins of interest and target them to the intracellular protein recycling machinery for targeted protein degradation have recently emerged as powerful tools for undruggable targets in biomedical research and the pharmaceutical industry. However, targeting any new protein of interest with current degradation tools requires a laborious case-by-case design for different diseases and cell types, especially for extracellular targets. Here we observe that nanoparticles can mediate specific receptor-independent internalization of a bound protein and further develop a general strategy for degradation of extracellular proteins of interest by making full use of clinically approved components.

Fluorinated aggregated nanocarbon with high discharge voltage as cathode materials for alkali-metal primary batteries.

Due to its exceptionally high theoretical energy density, fluorinated carbon has been recognized as a strong contender for the cathode material in lithium primary batteries particularly valued in aerospace and related industries. However, CF cathode with high F/C ratio, which enables higher energy density, often suffer from inadequate rate capability and are unable to satisfy escalating demand. Furthermore, their intrinsic low discharge voltage imposes constraints on their applicability.

Peptide inhibitors targeting Ras and Ras-associated protein-protein interactions.

Peptides represent attractive molecules for targeting protein-protein interactions, and peptide drug development has made great progress during the last decades. Ras protein, the most promising target in cancer therapy, is one of the major growth drivers in various cancers. Although many small molecule inhibitors have been reported to effectively target Ras protein and some inhibitors (such as MRTX849 and AMG 510) have been translated into clinical application, just a few peptide inhibitors have been reported.
