Measuring traveling wave velocity in the basilar membrane as a potential indicator of endolymphatic hydrops in definite Ménière's disease: a narrative review.

Background: The pathological hallmark of Ménière's disease is endolymphatic hydrops, which can lead to an increase in basilar membrane stiffness and, consequently, an acceleration of the traveling wave of sound. The cochlear hydrops analysis masking procedure (CHAMP), which is an auditory brainstem response test masked at various frequencies with high-pass noise masking, uses the principle of the traveling wave velocity theory to determine the presence of endolymphatic hydrops.

Purpose: This study aimed to review the previous results of the CHAMP, expound the principles and key indicators, and discuss its clinical significance in diagnosing Ménière's disease.

Acupuncture for angina post percutaneous coronary intervention: a protocol for systematic review and meta-analysis.

Introduction: Ischaemic heart disease (IHD) is a pathological process characterised by a blockage or non-obstructive accumulation of atherosclerotic plaques in the epicardial arteries. Percutaneous coronary intervention (PCI) is widely used in clinical practice to treat IHD. However, angina post PCI (APPCI) impairs quality of life and portends a worse prognosis.

Acute thrombosis of ductus arteriosus aneurysm causing bilateral pulmonary artery occlusion in a neonate.

A 9-day-old male neonate was found to have a systolic murmur during a routine follow-up for skin jaundice. Imaging revealed a large mass at the bifurcation of the main pulmonary artery, causing significant bilateral stenosis. The patient underwent emergency surgery due to critically compromised pulmonary blood flow.

In vitro digestion of glycoproteins from Porphyra haitanensis: Effects on structure, hypoglycemic activity, and fermentation characteristics.

This study was to investigate the fundamental composition and structure, hypoglycemic activity and fermentation characteristics of Porphyra haitanensis glycoprotein (PG) following in vitro simulate gastrointestinal digestion. After in vitro digestion, PG was degraded into peptides, amino acids, and reducing sugars, and the digested PG structure evolved into functional aggregates that were more favorable for regulating intestinal flora. Such aggregated structure might inhibit the accessibility of digestive enzymes and significantly enhanced its hypoglycemic activity.

Bioinspired Iron Porphyrin Covalent Organic Frameworks-Based Nanozymes Sensor Array: Machine Learning-Assisted Identification and Detection of Thiols.

Given the crucial role of thiols in maintaining normal physiological functions, it is essential to establish a high-throughput and sensitive analytical method to identify and quantify various thiols accurately. Inspired by the iron porphyrin active center of natural horseradish peroxidase (HRP), we designed and synthesized two iron porphyrin covalent organic frameworks (Fe-COF-H and Fe-COF-OH) with notable peroxidase-like (POD) activity, capable of catalyzing 3,3',5,5'-tetramethylbenzidine (TMB) into oxidized TMB with three distinct absorption peaks. Based on these, a six-channel nanozyme colorimetric sensor array was constructed, which could map the specific fingerprints of various thiols.

Comparative Study on the Electrocatalytic Performance of ABO-Based Hexagonal Perovskite Oxides with Different [AO] Layers.

To systematically investigate the influence of the number of [AO] layers in the unit cell of hexagonal perovskite oxide on the oxygen evolution reaction performance, we successfully synthesized the three new hexagonal perovskite oxides 2H-BaCoRuO, 6H-BaCoRuO, and 10H-BaCoRuO with the same element composition but different [BaO] layers via the sol-gel method. Here, 2H, 6H, and 10H refer to the number of [BaO] layers contained in the unit cell of the BaCoRuO system. Experimentally, 10H-BaCoRuO, featuring ten layers of [BaO], exhibits optimal electrochemical activity among the three oxide catalysts, and in situ Raman results under various bias voltages confirm its ability to maintain a high surface crystal structural stability.

Here, a high-quality chromosome-level genome of O.

Associated factors and outcomes for quality of life in children receiving cochlear implantation before seven years of age.

Purpose: To evaluate the relationship of cochlear implant-related factors with quality of life (QOL) outcomes in pediatric cochlear implantation (CI) recipients.

Method: In this cross-sectional study, data from 146 children who received CI before 7 years of age were collected. QOL was measured using the Children using Hearing Implants Quality of Life (CuHI-QoL) questionnaire.

The de-sulfinylation enzyme sulfiredoxin-1 attenuates hepatic stellate cell activation and liver fibrosis by modulating the PTPN12-NLRP3 axis.

Background Aims: Liver fibrosis is characterized by the progressive scarring of liver tissue. Oxidative stress is a critical causal factor of hepatic stellate cell (HSC) activation and the subsequent liver fibrogenesis, but the mechanism is not fully understood. Cysteine sulfinic acid (Cys-SO2H), a modification of reactive cysteine residues, is a unique form of oxidative response that alters the structure and function of proteins.

Electroconvulsive Therapy Regulates the Interhemispheric Functional Connectivity of the Dorsomedial Prefrontal Cortex in Depressive Patients: Evidence from 2 Independent Samples.

Background: The dorsomedial prefrontal cortex (dmPFC) is considered a crucial node in emotional and cognitive processes. Voxel-mirrored homotopic connectivity (VMHC) is a validated methodology for investigating interhemispheric coordination. This study aims to elucidate the effects of electroconvulsive therapy (ECT) on the interhemispheric connectivity of the dmPFC in patients with depression, using VMHC as a measure of bilateral neural coordination.

Super-enhancer-driven ZFP36L1 promotes PD-L1 expression in infiltrative gastric cancer.

Gastric cancer (GC) is a major cause of cancer-related mortality worldwide. Despite the widespread recognition of tumor immunotherapy in treating unresectable GC, challenges, including ineffective immunotherapy and drug resistance, persist. Therefore, understanding the regulatory mechanisms of PD-L1, particularly in the context of super-enhancers (SEs) and zinc finger protein 36 ring finger protein-like 1 (ZFP36L1) RNA-binding protein, is crucial.

Unraveling the nexus of age, epilepsy, and mitochondria: exploring the dynamics of cellular energy and excitability.

Epilepsy, a complex neurological condition marked by recurring seizures, is increasingly recognized for its intricate relationship with mitochondria, the cellular powerhouses responsible for energy production and calcium regulation. This review offers an in-depth examination of the interplay between epilepsy, mitochondrial function, and aging. Many factors might account for the correlation between epilepsy and aging.

A midgut transcriptional regulatory loop favors an insect host to withstand a bacterial pathogen.

Mounting evidence suggests that insect hormones associated with growth and development also participate in pathogen defense. We have discovered a previously undescribed midgut transcriptional control pathway that modulates the availability of 20-hydroxyecdysone (20E) in a worldwide insect pest (), allowing it to defeat the major virulence factor of an insect pathogen (Bt). A reduction of the transcriptional inhibitor (PxDfd) increases the expression of a midgut microRNA (miR-8545), which in turn represses the expression of a newly identified ecdysteroid-degrading glucose dehydrogenase (PxGLD).
