Utilization of Cardiac Magnetic Resonance Imaging for Assessing Myocardial Fibrosis in Prognosis Evaluation and Risk Stratification of Patients with Dilated Cardiomyopathy.

Dilated cardiomyopathy (DCM) is the ultimate manifestation of the myocardial response to various genetic and environmental changes and is characterized mainly by impaired left ventricular systolic and diastolic function. DCM can ultimately lead to heart failure, ventricular arrhythmia (VA), and sudden cardiac death (SCD), making it a primary indication for heart transplantation. With advancements in modern medicine, several novel techniques for evaluating myocardial involvement and disease severity from diverse perspectives have been developed.

A single fluorescent probe to examine the dynamics of mitochondria-lysosome interplay and extracellular vesicle role in ferroptosis.

Ferroptosis is a non-apoptotic form of cell death characterized by iron-dependent lipid peroxidation and glutathione (GSH) depletion. Despite recent advances, challenges remain in understanding the bidirectional interactions or interplay between organelles during ferroptosis. In this study, we aimed to understand the interplay between mitochondria (Mito) and lysosomes (Lyso) in cell homeostasis and ferroptosis.

Association between late gadolinium enhancement and outcome in dilated cardiomyopathy: A meta-analysis.

Application of instantaneous nebulization dispersive liquid-phase microextraction combined with HPLC for the determination of chalcone and isoflavone in traditional Chinese medicines.

A simple and rapid instantaneous nebulization dispersive liquid-phase microextraction method was developed, and combined with high-performance liquid chromatography for determination of the contents of seven analytes in traditional Chinese medicines. In this study, using the sprinkler device to achieve instantaneous synchronous dispersion and extraction, only one spray can rapidly achieve the concentration and enrichment of seven kinds of chalcone and isoflavones. The key factors affecting the extraction efficiency were optimized including the type and volume of extractant, the pH and salt concentration of the sample phase, and the number of dispersion.

(L.) Lam. Fruit Accelerates Healing in Gastric Injury via the Regulation of the NF-B Pathway.

Materials And Methods: The chemical components in the extract of BGF were used in UPLC/Q-Orbitrap analysis. 60 SD rats were randomized into six groups: normal group (MC), ethanol-injured control group (EC), omeprazole group, and three groups with different doses (50, 100, and 200 mg/kg) of BGF.

Isolation and Characterization of a Novel Lytic Halotolerant Phage from Yuncheng Saline Lake.

Halophilic phage are a type of virus that exist in salty environments within halophilic archaeal or bacterial hosts. However, relatively few reports on halophilic bacteriophages exist, and our overall understanding of halophilic bacteriophages is quite limited. We used SYBR Green I fluorescent staining to detect the abundance of viruses in Yuncheng Saline Lake, China.

Metabolomics and integrated network pharmacology analysis reveal attenuates cardiac hypertrophic mechanisms of HuoXin pill.

Ethnopharmacological Relevance: Cardiac hypertrophy (CH) is maladaptive and contributes to the pathogenesis of heart failure. Huoxin pill (HXP), a Chinese herbal prescription, is widely applied in the treatment of cardiovascular disease (CAD). Its mechanism, however, is unclear.

Simultaneous imaging of hypochlorous acid and nitric oxide in live cells based on a dual-channel fluorescent probe.

Both reactive oxygen species (ROS) and reactive nitrogen species (RNS) are inevitably produced during normal human metabolism. Various ROS and RNS together form tangled networks that play important roles in many physiological and pathological processes. Here we used 1,8-naphthalene diamine as a reactive group to develop a fluorescent probe, N-[2-(6-phenylethynyl)quinolinylmethyl]-1,8-diamino naphthalene (QBN), for HOCl and NO.

[Effect of density and directional cultivation on yield, quality and benefit of Nuomi yam].

A split-plot experiment was conducted to study the optimum planting density of Nuomi yam in directional groove shallow cultivation. Nuomi yam was the main local cultivar of Dioscorea. The study of this paper may help to give valuable instructions of local production.

Matrix Metalloproteinases (MMPs) in Targeted Drug Delivery: Synthesis of a Potent and Highly Selective Inhibitor against Matrix Metalloproteinase- 7.

Background: Matrix metalloproteinases (MMPs) are a family of zinc endopeptidases that play a key role in both physiological and pathological tissue degradation. MMPs have reportedly shown great potentials in the degradation of the Extracellular Matrix (ECM), have shown great potentials in targeting bioactive and imaging agents in cancer treatment. MMPs could provoke Epithelial to Mesenchymal Transition (EMT) of cancer cells and manipulate their signaling, adhesion, migration and invasion to promote cancer cell aggressiveness.

The crucial role of metabolic regulation in differential hepatotoxicity induced by furanoids in Dioscorea bulbifera.

Diterpenoid lactones (DLs), a group of furan-containing compounds found in Dioscorea bulbifera L. (DB), have been reported to be associated with hepatotoxicity. Different hepatotoxicities of these DLs have been observed in vitro, but reasonable explanations for the differential hepatotoxicity have not been provided.

Design and synthesis of α-naphthoflavone chimera derivatives able to eliminate cytochrome P450 (CYP)1B1-mediated drug resistance via targeted CYP1B1 degradation.

Extrahepatic cytochrome P450 1B1 (CYP1B1), which is highly expressed in various tumors, is an attractive and potential target for cancer prevention, therapy, and reversal of drug resistance. CYP1B1 inhibition is the current predominant therapeutic paradigm to treating CYP1B1-mediated malignancy, but therapeutic effect has little success. Herein, we reported CYP1B1 degradation in place of CYP1B1 inhibition for reversing drug resistance toward docetaxel in CYP1B1-overexpressing prostate cancer cell line DU145 using a PROTAC strategy.

Integration of transcriptomics and metabolomics profiling reveals the metabolic pathways affected in dictamnine-induced hepatotoxicity in mice.

However, the underlying mechanisms remain unknown. Using the integrated transcriptomic and metabolomics method, in this study we investigated the global effect of EEA exposure on the transcriptomic and metabolomic profiles in mice.

Salisbury screen optical color filter with ultra-thin titanium nitride film.

Titanium nitride (TiN) is a metal-like refractory material that can be used as a substitution for metals in many applications. In this paper, we report the use of an ultra-thin TiN film in the Salisbury screen structure to spectral selectively absorb visible light for forming an optical color filter. The ultra-thin TiN film functions as a partial reflector as well as a protection capping layer in the structure.

Rapid detection of PAH gene mutations in Chinese people.

Background: Phenylketonuria (PKU) is an autosomal recessive genetic disease, caused by the phenylalanine hydroxylase (PAH) deficiency in the metabolic pathway, which prevents phenylalanine from being converted into tyrosine, leading to a large amount of phenylalanine discharged from the urine. Therefore, it is necessary to establish a simple, fast, accurate and reliable PKU molecular diagnostic method for clinical diagnosis.

Methods: We established a novel diagnostic method by combining a single-tube multiplex PCR technique with molecular hybridization technique.

The Modulatory Role of CYP3A4 in Dictamnine-Induced Hepatotoxicity.

Dictamni Cortex (DC) has been reported to be associated with acute hepatitis in clinic and may lead to a selective sub-chronic hepatotoxicity in rats. Nevertheless, the potent toxic ingredient and the underlying mechanism remain unknown. Dictamnine (DTN), the main alkaloid from DC, possesses a furan ring which was suspected of being responsible for hepatotoxicity via metabolic activation primarily by CYP3A4.
