Therapeutic Targets and Natural Product Screening for Cognitive Impairments Associated with Ferroptosis in Wilson's Disease.

Wilson's disease (WD) is a hereditary condition marked by abnormalities in copper metabolism, which precipitate a spectrum of neurological symptoms and cognitive impairments. Emerging research has highlighted ferroptosis (FPT) as a distinct type of programmed cell death, potentially linked to various cognitive dysfunctions. Nevertheless, the connection between FPT and cognitive impairment in Wilson's disease (WDCI) remains largely enigmatic.

In this work, 4-carboxyphenylboronic acid was grafted onto the side chains of hydroxyethyl cellulose and compounded with inexpensive cornstarch. Upon the introduction of tannic acid, stable and reversible borate ester bond rapidly formed, yielding composite biodegradable plastic films with outstanding mechanical properties and facile recyclability.

Tröger's Base-Embedded Pillararenes─Macrocycles with Both Fixed and Conformational Chirality.

Tröger's base-embedded pillararenes (), which combine Tröger's base () with dialkoxybenzene units, were prepared via a fragment-coupling macrocyclization strategy. The unit in macrocycle provides a fixed chiral source, while 1,4-alkoxybenzene segments flip quickly to change their arrangement, which could provide reversible conformational chirality for those macrocycles. This rare example of macrocycles holding both fixed and conformational chirality lays a good foundation for expanding pillararenes using the fixed chiral source.

Binuclear Enamino-Oxazolinate Rare-Earth Metal Complexes: Synthesis and Their Catalytic Performance in Isoprene Polymerization.

We have synthesized a series of binuclear rare-earth metal complexes bearing the newly designed enamino-oxazolinate ligands that feature bridging -phenyl, -phenyl, 1,5-naphthalenyl, and 1,5-anthracenyl moieties.

Objective: Emerging evidence has shown that gut diseases can regulate the development and function of the immune, metabolic, and nervous systems through dynamic bidirectional communication on the brain-gut axis.

Pillarurilarenes: Glycoluril-Expanded Pillararenes.

Glycoluril-expanded pillararenes composed of glycoluril and dialkoxybenzene units, namely, pillarurilarenes (), were synthesized through a fragment coupling macrocyclization strategy. Partial replacement of dialkoxybenzene with glycoluril endows with polarized equatorial methine protons for derivatization or CH-anion binding. Crystal structures of pillar[2]uril[4]arene and pillar[1]uril[4]arene containing two glycoluril units and one glycoluril unit, respectively, indicated the inward orientation of the glycoluril unit, as also suggested by H nuclear magnetic resonance and density functional theory calculation.

Genetic causal relationship between multiple immune cell phenotypes and Parkinson's disease: a two-sample bidirectional Mendelian randomization study.

The exact etiology of Parkinson's disease (PD), a degenerative disease of the central nervous system, is unclear. It is currently believed that its main pathological basis is a decrease in dopamine concentration in the striatum of the brain. Although many researchers have previously focused on the critical role of the immune response in PD, there has been a lack of valid genetic evidence for a causal association between specific immune cell traits and phenotypes and PD.

Dynasore Alleviates LPS-Induced Acute Lung Injury by Inhibiting NLRP3 Inflammasome-Mediated Pyroptosis.

Application of flipped classroom teaching method based on ADDIE concept in clinical teaching for neurology residents.

Background: As an important medical personnel training system in China, standardized residency training plays an important role in enriching residents' clinical experience, improving their ability to communicate with patients and their clinical expertise. The difficulty of teaching neurology lies in the fact that there are many types of diseases, complicated conditions, and strong specialisation, which puts higher requirements on residents' independent learning ability, the cultivation of critical thinking, and the learning effect. Based on the concept of ADDIE (Analysis-Design-Development-Implementation-Evaluation), this study combines the theory and clinical practice of flipped classroom teaching method to evaluate the teaching effect, so as to provide a basis and reference for the implementation of flipped classroom in the future of neurology residency training teaching.

Evidence for genetic causality between iron homeostasis and Parkinson's disease: A two-sample Mendelian randomization study.

Background: Parkinson's disease (PD) is a degenerative disease of the central nervous system, and its specific etiology is still unclear. At present, it is believed that the main pathological basis is the reduction of dopamine concentration in the brain striatum. Although many previous studies have believed that iron as an important nutrient element participates in the occurrence and development of PD, whether there is a causal correlation between total iron binding capacity(TIBC), transferring saturation(TSAT), ferritin and serum iron in iron homeostasis indicators and PD, there has been a lack of effective genetic evidence.

Interfacial π-p Electron Coupling Prompts Hydrogen Evolution Reaction Activity in Acidic Electrolyte.

The thermodynamically stable 2H-phase MoS is a brilliant material toward hydrogen evolution reaction (HER) owing to its excellent Gibbs free energy of hydrogen adsorption. Nevertheless, the poor intrinsic properties of 2H-MoS limit its electrocatalytic performances toward HER. In this work, graphitic carbon nitride covalently bridging 2H-MoS (MoS/GCN) is proposed to construct robust HER electrocatalysts.

V-ATPase recruitment to ER exit sites switches COPII-mediated transport to lysosomal degradation.

Endoplasmic reticulum (ER)-phagy is crucial to regulate the function and homeostasis of the ER via lysosomal degradation, but how it is initiated is unclear. Here we discover that Z-AAT, a disease-causing mutant of α1-antitrypsin, induces noncanonical ER-phagy at ER exit sites (ERESs). Accumulation of misfolded Z-AAT at the ERESs impairs coat protein complex II (COPII)-mediated ER-to-Golgi transport and retains V0 subunits that further assemble V-ATPase at the arrested ERESs.
