Cardiotoxicity of polystyrene nanoplastics and associated mechanism of myocardial cell injury in mice.

Aims: Nanoplastics (NPs) are emerging organic pollutants generated by plastic degradation and are ubiquitous in the environment. They can be accumulated through the food webs and enter the human body through dietary intake, posing health risks. The main target organs of NP accumulation are the lungs, liver, heart, and kidneys.

Rh-relaxin-2 attenuates oxidative stress and neuronal apoptosis via ERK-nNOS-NO pathway after germinal matrix hemorrhage in rats.

Oxidative stress and neuronal apoptosis could be an important factor leading to post-hemorrhagic consequences after germinal matrix hemorrhage (GMH). Previously study have indicated that relaxin 2 receptor activation initiates anti-oxidative stress and anti-apoptosis in ischemia-reperfusion injury. However, whether relaxin 2 activation can attenuate oxidative stress and neuronal apoptosis after GMH remains unknown.

METTL14 Promotes the Osteogenic Differentiation of Human Bone Marrow Stromal Cells via m6A-Dependent Stabilization of USP7 mRNA.

Osteoporosis (OP) is a common clinical bone disease that can cause a high incidence of non-stress fractures and is one of the main degenerative diseases that endangers the health and life of middle-aged and older women. The mechanism underlying the abnormal differentiation and function of human bone marrow stem cells (hBMSCs) remains to be elucidated. Cell proliferation and differentiation were determined using 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay, alkaline phosphatase (ALP) staining, and Alizarin Red Staining.

Integrating single-cell RNA-Seq and bulk RNA-Seq data to explore the key role of fatty acid metabolism in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a predominant cause of cancer-related mortality globally, noted for its propensity towards late-stage diagnosis and scarcity of effective treatment modalities. The process of metabolic reprogramming, with a specific emphasis on lipid metabolism, is instrumental in the progression of HCC. Nevertheless, the precise mechanisms through which lipid metabolism impacts HCC and its viability as a therapeutic target have yet to be fully elucidated.

Targeting FOXM1 condensates reduces breast tumour growth and metastasis.

Identifying phase-separated structures remains challenging, and effective intervention methods are currently lacking. Here we screened for phase-separated proteins in breast tumour cells and identified forkhead (FKH) box protein M1 (FOXM1) as the most prominent candidate. Oncogenic FOXM1 underwent liquid-liquid phase separation (LLPS) with FKH consensus DNA element, and compartmentalized the transcription apparatus in the nucleus, thereby sustaining chromatin accessibility and super-enhancer landscapes crucial for tumour metastatic outgrowth.

Protective effects of wogonin in the treatment of central nervous system and degenerative diseases.

Wogonin, an O-methylated flavonoid extracted from Scutellaria baicalensis, has demonstrated profound neuroprotective effects in a range of central nervous system (CNS) diseases. This review elucidates the pharmacological mechanisms underlying the protective effects of wogonin in CNS diseases, including ischemic stroke, hemorrhagic stroke, traumatic brain injury, epilepsy, anxiety, neurodegenerative diseases, and CNS infections. Wogonin modulates key signaling pathways, such as the MAPK, NF-κB, and ROS pathways, contributing to its anti-inflammatory, antioxidant, and antiapoptotic properties.

Androgen deficiency-induced loss of Lactobacillus salivarius extracellular vesicles is associated with the pathogenesis of osteoporosis.

Male osteoporosis is primarily caused by a decrease in testicular testosterone production. Male osteoporosis remains a disease with insufficient diagnosis and treatment, and its consequences are severe, especially in older patients. The gut microbiota plays a crucial role in its occurrence and development.

The impact of metabolic syndrome on hepatocellular carcinoma: a mendelian randomization study.

Traditional epidemiological studies are susceptible to confounding factors. To clarify the impact of metabolic syndrome and its diagnostic components on hepatocellular carcinoma, we conducted a preliminary mendelian randomization analysis with metabolic syndrome and its diagnostic components as exposures and hepatocellular carcinoma as the outcome. Another set of genetic data related to hepatocellular carcinoma was used as a validation cohort, repeating the mendelian randomization analysis and combining the two groups for a meta-analysis.

The value of metagenomic next-generation sequencing in the diagnosis of fever of unknown origin.

Fever of unknown origin (FUO) caused by infection is a disease state characterized by complex pathogens and remains a diagnostic dilemma. Metagenomic next-generation sequencing (mNGS) technology is a promising diagnostic tool for identifying pathogenic microbes of FUO caused by infection. Little is known about the clinical impact of mNGS in the etiological diagnosis of FUO.

Differentiation between multiple sclerosis and neuromyelitis optic spectrum disorders with multilevel fMRI features: A machine learning analysis.

The conventional statistical approach for analyzing resting state functional MRI (rs-fMRI) data struggles to accurately distinguish between patients with multiple sclerosis (MS) and those with neuromyelitis optic spectrum disorders (NMOSD), highlighting the need for improved diagnostic efficacy. In this study, multilevel functional metrics including resting state functional connectivity, amplitude of low frequency fluctuation (ALFF), and regional homogeneity (ReHo) were calculated and extracted from 116 regions of interest in the anatomical automatic labeling atlas. Subsequently, classifiers were developed using different combinations of these selected features to distinguish between MS and NMOSD.

Rapamycin protects glucocorticoid-induced glaucoma model mice against trabecular meshwork fibrosis by suppressing mTORC1/2 signaling.

Systemic or local use of glucocorticoids (GCs) can induce pathological elevation of intraocular pressure (IOP), potentially leading to permanent visual loss. Previous studies have demonstrated that rapamycin (Rapa) inhibits the activation of retinal glial cells (RGC) and the production of neuroinflammation, achieving neuroprotective goals. However, there has been little research on the effect of Rapa on the trabecular meshwork (TM).

The sucrase-isomaltase (SI) enzyme is the primary target of acarbose. This study aims to investigate the impact of genetic polymorphisms in the SI gene on the pharmacodynamics of acarbose.

Characterization and genomic insights into bacteriophages Kpph1 and Kpph9 against hypervirulent carbapenem-resistant .

The increasing incidence of infections attributed to hypervirulent carbapenem-resistant (Hv-CRKp) is of considerable concern. Bacteriophages, also known as phages, are viruses that specifically infect bacteria; thus, phage-based therapies offer promising alternatives to antibiotic treatments targeting Hv-CRKp infections. In this study, two isolated bacteriophages, Kpph1 and Kpph9, were characterized for their specificity against the Hv-CRKp NUHL30457 strain that possesses a K2 capsule serotype.
