Discrimination, Drinking to Cope, Protective Behavioral Strategies, and Alcohol-Related Consequences Among University Students.

Objective: University students who experience more discrimination typically report more negative consequences from alcohol use. The study aimed to assess whether drinking to cope and protective behavioral strategies for alcohol use would help explain the relationship between everyday discrimination and alcohol-related consequences among university student drinkers.

Method: Data were collected in Fall 2020, and the sample included 707 undergraduate and graduate students from a large public institution in the Northeast who reported consuming alcohol in the past month.

Regulation of astrocyte activity and immune response on graphene oxide-coated titanium by electrophoretic deposition.

Astrocytes play crucial role in modulating immune response in the damaged central nervous system. Numerous studies have investigated the relationship between immune responses in astrocytes and brain diseases. However, the potential application of nanomaterials for alleviating neuroinflammation induced by astrocytes remains unexplored.

Drinking to cope with COVID-19 anxiety predicts greater alcohol problems for undergraduate students.

Drinking more and drinking to cope increase undergraduates' likelihood of experiencing alcohol-related problems (ARP; e.g., driving intoxicated).

Injectable remodeling hydrogels derived from alendronate-tethered alginate calcium complex for enhanced osteogenesis.

A combination of hydrogel materials, and therapeutic agents have been actively reported to facilitate bone defect healing. However, conventionally hydrogels using cross-linker would result in low stability of the hydrogel itself, loss of agents during cross-linking, and complexity of use. In this study, alendronate was tethered to an AlA to improve its bone healing and drug-loading stability.

Enhanced Effect of Polyethyleneimine-Modified Graphene Oxide and Simvastatin on Osteogenic Differentiation of Murine Bone Marrow-Derived Mesenchymal Stem Cells.

Statin derivatives traditionally have been used for the treatment of hyperlipidemia, but recent studies have shown their ability to regulate bone metabolism and promote bone growth. In this study, simvastatin (Sim), a new therapeutic candidate for bone regeneration, was combined with graphene oxide (GO), which has recently attracted much interest as a drug delivery method, to produce a compound substance effective for bone regeneration. To create a stable and homogenous complex with Sim, GO was modified with polyethylenimine, and the effect of modification was analyzed using Fourier transform infrared spectroscopy, zeta potential, and cytotoxicity testing.

Light-controlled growth factors release on tetrapodal ZnO-incorporated 3D-printed hydrogels for developing smart wound scaffold.

Advanced wound scaffolds that integrate active substances to treat chronic wounds have gained significant recent attention. While wound scaffolds and advanced functionalities have previously been incorporated into one medical device, the wirelessly triggered release of active substances has remained the focus of many research endeavors. To combine multiple functions including light-triggered activation, anti-septic, angiogenic, and moisturizing properties, we have developed a 3D printed hydrogel patch encapsulating vascular endothelial growth factor (VEGF) decorated with photoactive and antibacterial tetrapodal zinc oxide (t-ZnO) microparticles.

Engineered dressing of hybrid chitosan-silica for effective delivery of keratin growth factor and acceleration of wound healing.

Biological dressings composed of multi-components including extracellular matrix (ECM) materials and therapeutic agents for facilitating wound healing have been actively reported. To improve the wound healing ability of chitosan dressing, sol-gel derived silica was incorporated with chitosan and this chitosan-silica hybrid dressing was combined with keratinocyte growth factor (KGF) in this study. Such hybrid dressing showed higher efficacy of KGF adsorption than pure chitosan dressing due to its porous structure and hydrophilic character.

Facile in situ formation of hybrid gels for direct-forming tissue engineering.

Development of bioactive hydrogel as extracellular matrix (ECM) is a very important field for cell-based therapy. In this study, we provided a facile method based on sol-gel process for fabricating bioactive composite hydrogels. The composite hydrogels were composed of sol-gel derived silica and biopolymer.
