Association between neutrophil to high-density lipoprotein ratio and no-reflow after coronary intervention: A cross-sectional study.

Inflammatory responses and lipid metabolism disorders are key components in the development of coronary artery disease and contribute to no-reflow after coronary intervention. This study aimed to investigate the association between the neutrophil to high-density lipoprotein ratio (NHR) and no-reflow phenomenon in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PPCI). This study enrolled 288 patients with STEMI from September 1st, 2022 to February 29th, 2024, in the Zhengzhou Central Hospital Affiliated to Zhengzhou University.

Discovery of First-in-Class FXR and HSD17B13 Dual Modulator for the Treatment of Metabolic Dysfunction-Associated Fatty Liver Disease.

Metabolic dysfunction-associated steatohepatitis (MASH) is a complex disease driven by diverse metabolic and inflammatory pathways. Farnesoid X receptor (FXR) is a promising target for MASH due to its role in bile acid and lipid metabolism, while HSD17B13 regulates liver lipid droplet homeostasis. However, the existing HSD17B13 inhibitors have several druglike property challenges due to the common phenolic structure, a key pharmacophore for the HSD17B13 inhibitor.

A novel method for detecting intracranial pressure changes by monitoring cerebral perfusion via electrical impedance tomography.

Background: Acute and critical neurological diseases are often accompanied with elevated intracranial pressure (ICP), leading to insufficient cerebral perfusion, which may cause severe secondary lesion. Existing ICP monitoring techniques often fail to effectively meet the demand for real-time noninvasive ICP monitoring and warning. This study aimed to explore the use of electrical impedance tomography (EIT) to provide real-time early warning of elevated ICP by observing cerebral perfusion.

Precise Electron-Withdrawing Strength Regulation of π-Conjugate Bridge-Boosted Specific Detection toward α-Methyltryptamine.

The specific fluorescent detection of α-methyltryptamine (AMT) presents a great challenge because similar amine groups and benzene rings exist in a variety of amines. Here, we show the precise modulation of the electron-withdrawing strength of the π-conjugate bridge in aldehyde-containing Schiff base-based fluorescent probes for ultratrace AMT discrimination. It is found that different electron-withdrawing groups -CH, -CHN, and -CHBr as the π-conjugate bridge of the 2-dicyanomethylidene-3-cyano-4,5,5-trimethyl-2,5-dihydrofuran (TCF)-based probes can classify and identify organic amines with different amine nucleophilicities.

Anti-PD-1 therapy, effective in patients with various advanced tumors, still encounters the challenge of insensitivity in most patients. Here, we demonstrate that PD-L1 on tumor cell-derived extracellular vesicles (TEVs) is critical for anti-PD-1 therapy resistance. Reducing endogenous and transferring exogenous TEVs abrogates and induces anti-PD-1 therapy resistance, respectively.

Surgical options for Evans-Jensen type IV intertrochanteric femur fractures in the elderly over 65: a comparison between total hip arthroplasty and proximal femoral nail antirotation.

Background: Currently, there is no clear standard for the surgical options for Evans-Jensen Type IV intertrochanteric femur fractures in elderly patients over 65 years old. This study aims to retrospectively analyze and compare the early postoperative limb function and quality of life of patients treated with total hip arthroplasty (THA) and proximal femoral nail antirotation (PFNA) for this type of fracture. We hypothesize that there is no significant difference in complications and postoperative recovery between the two surgical methods.

Polycalmagite Coating Enables Long-Term Alkaline Seawater Oxidation Over NiFe Layered Double Hydroxide.

However, severe chlorideions (Cl) and their derivatives tend to corrode anodic catalysts at ampere-level current densities and hinder the application of seawater-to-H systems. Herein, a polycalmagite (PCM)-coated NiFe layered double hydroxide is presented on Ni foam (NiFe LDH@PCM/NF) that exhibits exceptional stability in alkaline seawater.

High-prediction QSAR Modeling Study Based on the Efficacy of a Novel 6-hydroxybenzothiazole-2-carboxamide Targeted Monoamine Oxidase B in the Treatment of Neurodegenerative Diseases.

Background: Neurodegenerative diseases are a group of disorders characterized by progressive neuronal degeneration and death, of which Alzheimer's disease and Parkinson's disease are the most common. These diseases are closely associated with increased expression of monoamine oxidase B (MAO-B), an important enzyme that regulates neurotransmitter concentration, and its overactivity leads to oxidative stress and neurotoxicity, accelerating the progression of neurodegenerative diseases. Therefore, the development of effective MAO-B inhibitors is important for the treatment of neurodegenerative diseases.
