Background: Diallyl trisulfide (DATS) has a direct antioxidant capacity and emerges as a promising neuroprotective agent. This study was designed to investigate the role of DATS in traumatic brain injury (TBI).

Methods: TBI mouse models were established using the controlled cortical impact, followed by DATS administration.

In recent years, stem cells and their secretomes, notably exosomes, have received considerable attention in biomedical applications. Exosomes are cellular secretomes used for intercellular communication. They perform the function of intercellular messengers by facilitating the transport of proteins, lipids, nucleic acids, and therapeutic substances.

This study focused on unravelling the role of PCAT-1 in wound-healing process, particularly its impact on regenerative and osteogenic abilities of mesenchymal stem cells (MSCs). We delved into how PCAT-1 regulates mitochondrial oxidative phosphorylation (OXPHOS) and interacts with pivotal molecular pathways, especially β-catenin and PKM2, using human bone marrow-derived MSCs. MSCs were cultured under specific conditions and PCAT-1 expression was modified through transfection.

Periodontitis is a prevalent disease and one of the leading causes of tooth loss. Biofilms are initiating factor of periodontitis, which can destroy periodontal tissue by producing virulence factors. The overactivated host immune response is the primary cause of periodontitis.

Over the last two decades, the process of delivering therapeutic drugs to a patient with a controlled release profile has been a significant focus of drug delivery research. Scientists have given tremendous attention to ultrasound-responsive hydrogels for several decades. These smart nanosystems are more applicable than other stimuli-responsive drug delivery vehicles (ie UV-, pH- and thermal-, responsive materials) because they enable more efficient targeted treatment via relatively non-invasive means.

Patients with diabetes frequently suffer from periodontitis, which progresses rapidly and is difficult to cure. Mesenchymal stem cell (MSC) transplantation may effectively treat periodontitis, but high glucose limits its therapeutic effect in diabetes. Nerve growth factor (NGF) has the functions of cell protection, anti-apoptosis and immune regulation, and may have potential application in diabetic periodontitis.

The aim of the present study was to determine whether IL-6 polymorphisms correlate with sepsis. According to the inclusion criteria, the association of IL-6 polymorphisms with sepsis was searched in databases and analysed using comprehensive meta-analysis software. A total of 16 studies were included in this meta-analysis.

Atherosclerosis (AS) is an inflammatory disease that occurs in the arterial wall and is characterized by progressive lipid accumulation within the intima of large arteries, leading to the dysfunction of endothelial cells and further destruction of the endothelial barrier and vascular tone. Arterial intima injury accelerates the adhesion and activation of platelets at the injury site. The activation of platelets results in the secretion of growth factors, leading to the migration and proliferation of vascular smooth muscle cells (VSMCs), promoting the formation of plaque, resulting in the formation of thrombus.

The objective was to evaluate the fracture resistance properties of maxillary incisors with flared canals restored with computer aided design and computer aided manufacture (CAD/CAM) integrated glass fiber post-and-core. Thirty prepared flared root canals were selected in vitro and restored with CAD/CAM integrated fiber post-and-core (Group A), prefabricated fiber posts (Group B), and cast gold alloy (Group C), respectively. After submitted to fatigue loading, each specimen was subjected to a static loading until fracture.

The aim of this study was to isolate human mesenchymal stem cells (MSCs) from the gingiva (GMSCs) and confirm their multiple differentiation potentials, including the odontogenic lineage. GMSCs, periodontal ligament stem cells (PDLSCs) and dermal stem cells (DSCs) cultures were analyzed for cell shape, cell cycle, colony-forming unit-fibroblast (CFU-F) and stem cell markers. Cells were then induced for osteogenic and adipogenic differentiation and analyzed for differentiation markers (alkaline phosphatase (ALP) activity, mineralization nodule formation and Runx2, ALP, osteocalcin (OCN) and collagen I expressions for the osteogenic differentiation, and lipid vacuole formation and PPARγ-2 expression for the adipogenic differentiation).

Article Synopsis
  • A new 3D bilayered scaffold (GCH-GCBB) was created for repairing large joint defects in rabbits, mimicking natural cartilage and bone layers.
  • The scaffold's upper layer combines gelatin, chondroitin sulfate, and sodium hyaluronate, while the lower layer includes gelatin and ceramic bovine bone.
  • Results showed significant cartilage formation and bone replacement in the group treated with the scaffold and cells, whereas untreated groups displayed limited progress with fibrous tissue rather than cartilage.

Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia are oral pathogens associated with periodontitis. The association between these three bacteria and periodontal disease has been reported in populations of many countries. However, corresponding data in Chinese populations are still lacking.

An osteoblast-specific transcription factor, core binding factor alpha1 (Cbfalpha1), is critical for osteoblast and odontoblast differentiation. In this study, the role of Cbfalpha1 in human dentin matrix protein1 (DMP1) gene expression in human dental pulp stem cells (HDPSCs) was investigated. The desired promoter fragments were obtained and cloned into the pGL3-basic vector.

Article Synopsis
  • The study aimed to compare the activities of various length segments of the human dentin matrix protein 1 (Dmp1) promoter in three cell types: human dental pulp stem cells (HDPSC), osteoblasts (OC), and HeLa cells.
  • Different lengths of Dmp1 promoter DNA segments were cloned into a luciferase reporter vector, allowing researchers to measure luciferase activity across the different cell types after transfection.
  • Results showed that specific promoter segments had varying luciferase activities, with certain regions being effective in HDPSC and OC, while showing low activity in HeLa cells, indicating potential regulatory roles in mineralized tissue development.
