Progress in Research on Metal Ion Crosslinking Alginate-Based Gels.
Gels
December 2024
State Key Laboratory of Biobased Materials and Green Papermaking, Qilu University of Technology, Jinan 250353, China.
Alginate is an important natural biopolymer and metal ion-induced gelation is one of its most significant functional properties. Alginate-based hydrogels crosslinked with metal ions are commonly utilized in the food, biomedical, tissue engineering, and environment fields. The process of metal ion-induced alginate gelation has been the subject of thorough research over the last few decades.

To investigate the effect of concentrated growth factor (CGF) on the biological performance of human dental pulp stem cells (hDPSCs) under oxidative stress status induced by hydrogen peroxide (HO). The hDPSCs were isolated by using tissue block separation method from healthy permanent teeth extracted for orthodontic reason. hDPSCs surface markers CD34, CD45, CD90 and CD105 were detected by flow cytometry.

The aims of this study were to investigate the localization of non-phosphorylated β‑catenin and Galectin-3 (GAL-3), the regulation of the expression of both proteins by activation of estrogen receptors (ERs) and their role in tumorigenic characteristics of androgen-independent prostate cancer DU-145 cells. DU-145 cells were cultured in the absence (control), and presence of 17β-estradiol (E2). Cells were also untreated or pre-treated with the inhibitor of GAL‑3, VA03, or with a compound that disrupts the complex β-catenin-TCF/LEF transcription factor, PKF 118-310.

Background: Adamantane derivatives, such as memantine (Mem) and amantadine (Ada), have distinct mechanisms and therapeutic applications. Ada is primarily utilized as an antiviral and anti-Parkinson drug without significant pro-cognitive effects, Mem is effective in various clinical conditions characterized by cognitive deficits, including Alzheimer's disease. Recent evidence highlights a neuroprotective role for Aβ monomers, suggesting that preventing their aggregation into toxic oligomers could be a promising therapeutic strategy.

Chemerin, an adipocyte-secreted adipokine, can regulate bone resorption and bone formation and is a promising therapy for postmenopausal osteoporosis. However, the effect of endogenous chemerin on intraosseous vascular remodeling in postmenopausal osteoporosis remains unclear. In this study, we investigated the effect of chemerin on osteogenesis formation and intraosseous vascular remodeling in ovariectomized Rarres2 knockout (Rarres2) mice.
