Resveratrol alleviates heart failure by activating foxo3a to counteract oxidative stress and apoptosis.

Resveratrol has been extensively studied for its multifaceted health benefits. Nonetheless, the pharmacological mechanisms of resveratrol for heart failure remain elusive, especially the cardioprotective effects.

To address this knowledge gap, we investigated the effects of high-temperature stress on the transcriptomic landscape of the tilapia heart.

Reduced transcriptome analysis in zebrafish uncovers disruptors of spliceosome and ribosome biosynthesis.

Abnormal biosynthesis of spliceosomes and ribosomes can lead to their dysfunction, which in turn disrupts protein synthesis and results in various diseases. While genetic factors have been extensively studied, our understanding of how environmental compounds interfere with spliceosome and ribosome biosynthesis remains limited. In the present study, we employed a Reduced Transcriptome Analysis (RTA) approach, integrating large-scale transcriptome data sets of zebrafish and compiling a specific zebrafish gene panel focusing on the spliceosome and ribosome, to elucidate the potential disruptors targeting their biosynthesis.

Unveiling the Potential of Migrasomes: A Machine-Learning-Driven Signature for Diagnosing Acute Myocardial Infarction.

Background: Recent studies have demonstrated that the migrasome, a newly functional extracellular vesicle, is potentially significant in the occurrence, progression, and diagnosis of cardiovascular diseases. Nonetheless, its diagnostic significance and biological mechanism in acute myocardial infarction (AMI) have yet to be fully explored.

Small Peptides Isolated from Enzymatic Hydrolyzate of Bone Promote Sleep by Regulating Circadian Rhythms.

Due to the high addiction and side effects of medicines, people have increasingly inclined to natural and healthy peptides to improve sleep. Herein, we isolated novel peptides with sleep-promoting ability from bone peptides (PBPs) and constructed an insomniac zebrafish model as a demonstration, incorporating behavioral and transcriptomic approaches to reveal the sleep-promoting effect and mechanism of PBPs. Specifically, a sequential targeting isolation approach was developed to refine and identify a peptide with remarkable sleep-promoting activity, namely TG7 (Tyr-Gly-Asn-Pro-Trp-Glu-Lys).

This study aimed to investigate the immunological correlation and function of PTP1B in liver cancer.

Postural Control of Patients with Low Back Pain Under Dual-Task Conditions.

Low back pain is a major global public health problem, but the current intervention effect is not ideal. A large body of previous literature suggests that patients with chronic low back pain may have abnormal postural control, which is more evident in the dual task situation. In recent years, research on postural control in patients with low back pain under dual-task conditions has gradually become a hot topic.

Ultrasonography Comparison of Diaphragm Morphological Structure and Function in Young and Middle-Aged Subjects with and without Non-Specific Chronic Low Back Pain: A Case-Control Study.

Background: It is reported that impaired postural control in patients with non-specific chronic low back pain (NCLBP) was associated with "core" trunk muscle incoordination. However, as the diaphragm is an important component of the "core" deep trunk muscle group, we still know little about the potential relationship between diaphragm dysfunction and NCLBP.

Objectives: This case-control study is intended to investigate the changes of diaphragm morphological structure and function in young and middle-aged subjects with and without NCLBP by ultrasound evaluation and its possible validity in predicating the occurrence of NCLBP.

The etiologies and pathogenesis of dilated cardiomyopathy (DCM) with heart failure (HF) remain to be defined. Thus, exploring specific diagnosis biomarkers and mechanisms is urgently needed to improve this situation. In this study, three gene expression profiling datasets (GSE29819, GSE21610, GSE17800) and one single-cell RNA sequencing dataset (GSE95140) were obtained from the Gene Expression Omnibus (GEO) database.

Low-Cost and Rapid Method of DNA Extraction from Scaled Fish Blood and Skin Mucus.

PCR-based DNA amplification has been one of the major methods in aquaculture research for decades, although its use outside the modern laboratory environment is limited due to the relatively complex methods and high costs. To this end, we investigated a swabbing and disc protocol for the collection of DNA samples from fish which could extract DNA from fish skin mucus by a non-invasion technique costing only $0.02 (USD) and requiring less than 30 seconds.

Molecular Characterization and Chemotactic Function of CXCL8 in Northeast Chinese Lamprey ().

Chemokine-induced chemotaxis of leukocytes is an important part of the innate immunity and has been shown to mediate inflammation in all groups of jawed vertebrates. For jawless vertebrates, hagfish leukocytes are known to show chemotaxis toward mammalian complement anaphylotoxin and Gram-negative bacteria lipopolysaccharide. However, whether chemokines mediate chemotaxis of leukocytes in jawless vertebrates has not been conclusively examined.
