Exploration of Key Regulatory Factors in Mesenchymal Stem Cell Continuous Osteogenic Differentiation via Transcriptomic Analysis.

Background/objectives: Mesenchymal stem cells (MSCs) possess the remarkable ability to differentiate into various cell types, including osteoblasts. Understanding the molecular mechanisms governing MSC osteogenic differentiation is crucial for advancing clinical applications and our comprehension of complex disease processes. However, the key biological molecules regulating this process remain incompletely understood.

Injectable DMM/GelMA hydrogel for diabetic wound healing via regulating mitochondrial metabolism and macrophage repolarization.

The chronic diabetic wounds represented by diabetes foot ulcers (DFUs) are a worldwide challenge. Excessive production of reactive oxygen species (ROS) and persistent inflammation caused by the impaired phenotype switch of macrophages from M1 to M2 during wound healing are the main culprits of non-healing diabetic wounds. Therefore, an injectable DMM/GelMA hydrogel as a promising wound dressing was designed to regulate the mitochondrial metabolism of macrophages via inhibiting succinate dehydrogenase (SDH) activity and to promote macrophage repolarization towards M2 type.

Celastrol ameliorates lipopolysaccharide (LPS)-induced acute lung injury by improving mitochondrial function through AMPK/PGC-1α/Nrf1-dependent mechanism.

Acute lung injury (ALI) is a devastating clinical syndrome without effective therapy. Celastrol, as a natural anti-inflammatory compound, has showed therapeutic potential against inflammatory diseases. In this study, we have investigated the potential effect of Celastrol on lipopolysaccharide (LPS)-induced ALI.

Reliable and precise lipoprotein detection based on a self-priming hairpin-triggered Cas12a/crRNA based signaling strategy.

Cardiovascular disease, intimately linked to dyslipidemia, is one of the leading global causes of mortality. Dyslipidaemia often presents as an elevated concentration of low-density lipoprotein (LDL) and a decreased concentration of high-density lipoprotein (HDL). Therefore, accurately measuring the levels of LDL and HDL particles is crucial for assessing the risk of developing cardiovascular diseases.

Imbalance of intestinal flora activates inflammatory response contributing to acute lung injury.

Background: Seawater drowning is a leading cause of accidental injury and death, and the resulting acute lung injury (ALI) is a serious clinical syndrome for which there are no effective treatments. This study aims to investigate the potential mechanism of seawater drowning-induced ALI.

Methods: Seawater drowning mouse models were constructed to assess lung injury.

Prediction of intraoperative press-fit stability of the acetabular cup in total hip arthroplasty using radiomics-based machine learning models.

Background: Preoperative prediction of the acetabular cup press-fit stability in total hip arthroplasty is necessary for clinical decision-making. This study aims to establish and validate machine learning models to investigate the feasibility of predicting the intraoperative press-fit stability of the acetabular cup in total hip arthroplasty (THA).

Methods: 226 patients who underwent primary THA from 2018 to 2022 in our hospital were retrospectively enrolled.

Case Report: A case of rapamycin-eluting stent for the treatment of refractory stenosis of arteriovenous fistula stenosis.

For patients with repeated stenosis of autologous arteriovenous fistula, percutaneous transluminal angioplasty (PTA) or bare metal stent placement had limited efficacy. Rapamycin was reported to inhibit neointimal hyperplasia and keep blood vessels patent. In this study, we reported a case with refractory stenosis, i.

Early short-term hypoxia promotes epidermal cell migration by activating the CCL2-ERK1/2 pathway and epithelial-mesenchymal transition during wound healing.

Background: Due to vasculature injury and increased oxygen consumption, the early wound microenvironment is typically in a hypoxic state. We observed enhanced cell migration ability under early short-term hypoxia. CCL2 belongs to the CC chemokine family and was found to be increased in early hypoxic wounds and enriched in the extracellular signal-regulated kinase (ERK)1/2 pathway in our previous study.

The Effect of Coenzyme Q10 Supplementation on Bile Acid Metabolism: Insights from Network Pharmacology, Molecular Docking, and Experimental Validation.

Scope: Bile acids play a crucial role in lipid absorption and the regulation of lipid, glucose, and energy homeostasis. Coenzyme Q10 (CoQ10), a lipophilic antioxidant, has been recognized for its positive effects on obesity and related glycolipid metabolic disorders. However, the relationship between CoQ10 and bile acids has not yet been evaluated.

Prelimbic cortex-nucleus accumbens core projection positively regulates itch and itch-related aversion.

Itch is one of the most common clinical symptoms in patients with diseases of the skin, liver, or kidney, and it strongly triggers aversive emotion and scratching behavior. Previous studies have confirmed the role of the prelimbic cortex (Prl) and the nucleus accumbens core (NAcC), which are reward and motivation regulatory centers, in the regulation of itch. However, it is currently unclear whether the Prl-NAcC projection, an important pathway connecting these two brain regions, is involved in the regulation of itch and its associated negative emotions.

Post-marketing safety surveillance of dalfampridine for multiple sclerosis using FDA adverse event reporting system.

To investigate and analyze the post-marketing adverse event (AE) data of multiple sclerosis (MS) therapeutic drug dalfampridine using the US Food and Drug Administration Adverse Event Reporting System (FAERS) for its clinical safety application. Use OpenVigil2.1 platform to obtain AE data of dalfampridine from FAERS from February 2010 to September 2022.

The preferences for the telemedicine and standard health care services from the perspective of the patients with schizophrenia.

Background: With the rapid development of telemedicine, has enabled new and various ways to deliver health care services for patients with schizophrenia. However, it is not clear that the newly emerged is better than the standard or not from the perspective of patients with schizophrenia. This study aims to explore their preferences between telemedicine and standard health care services and their associated factors.

Phytic acid-modified manganese dioxide nanoparticles oligomer for magnetic resonance imaging and targeting therapy of osteosarcoma.

Osteosarcoma is the most common malignant tumor in the skeletal system with high mortality. Phytic acid (PA) is a natural compound extracted from plant seeds, which shows certain antitumor activity and good bone targeting ability. To develop a novel theranostics for magnetic resonance imaging (MRI) and targeting therapy of osteosarcoma, we employed PA to modify manganese dioxide nanoparticles (MnO@PA NPs) for osteosarcoma treatment.

Exploring the Antibacterial and Biosensing Applications of Peroxidase-Mimetic NiCuS Nanoflower.

Nanozymes, as artificial enzymes with the biological action of natural enzymes, have enormous potential in the fields of disease diagnosis, bacteriostasis, biosensing, etc. In this work, the NiCuS nanoflower was successfully synthesized through a one-step hydrothermal method.
