Background/objectives: Oral frailty, first identified in Japan in 2014, refers to a state between healthy oral function and severe decline, marked by minor issues, such as tooth loss and chewing difficulties. The oral frailty five-item checklist (OF-5) enables non-dental professionals to evaluate oral frailty using five key indicators: remaining teeth count, chewing difficulties, swallowing difficulties, dry mouth, and articulatory oral skills. Limited studies exist.

As the COVID-19 pandemic began in 2020, plastic usage spiked, and microplastic (MP) generation has increased dramatically. It is documented that MP can transfer from the source to the ocean environment where they accumulate as the destination. Therefore, it is essential to understand their transferring pathways and effective environmental factors to determine the distribution of MPs in the marine environment.

Article Synopsis
  • Chronic and inflammatory diseases often lead to a stiff extracellular matrix (ECM) and abnormal, leaky blood vessel formation, but how these blood vessels react to ECM changes is still unclear.
  • Researchers created a microphysiological chip model to simulate healthy and fibrotic collagen, hypothesizing that perivascular cells (surrounding cells of blood vessels) play a role in this response.
  • Their results showed that when perivascular cells interacted with altered fibrotic collagen, there were issues like cell migration problems, less pericyte differentiation, increased leakage, and more regulation of inflammatory genes, highlighting a new mechanism of how blood vessels respond to ECM changes.

The European Clozapine Task Force is a group of psychiatrists and pharmacologists practicing in 18 countries under European Medicines Agency (EMA) regulation, who are deeply concerned about the underuse of clozapine in European countries. Although clozapine is the most effective antipsychotic for people with treatment-resistant schizophrenia, a large proportion of them do not have access to this treatment. Concerns about clozapine-induced agranulocytosis and stringent blood monitoring rules are major barriers to clozapine prescribing and use.

Breast cancer remains a significant challenge in oncology, highlighting the need for alternative therapeutic strategies that target necroptosis to overcome resistance to conventional therapies. Recent investigations into natural compounds have identified 8,12-dimethoxysanguinarine (SG-A) from Eomecon chionantha as a potential necroptosis inducer. This study presents the first computational exploration of SG-A interactions with key necroptotic proteins-RIPK1, RIPK3, and MLKL-through molecular docking, molecular dynamics (MD), density functional theory (DFT), and molecular electrostatic potential (MEP) analyses.

Evid Based Dent

January 2025

Doctoral Research Fellow and Specialty Trainee (Endodontics), School of Dental Sciences, Faculty of Medical Sciences, Newcastle University, Newcastle Upon Tyne, UK.

Aims: This study aimed to assess the effectiveness of a novel antimicrobial gel, containing copper and silver nanoparticles, for use in root canal disinfection.

Methods: Copper and silver-based gels were created in-house, using a support network of biocompatible polymers, including polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), and polyethylene glycol (PEG). Six experimental groups were created, three containing silver ions and three copper ions, where the PVA, PVP and PEG ratios were also adjusted in each group to test the gel's physical state.

This study describes the potential of the conditioned medium (CM) from adipose-derived mesenchymal stromal cells (ASCs) to affect the response of bone cells and support bone remodeling. This was in particular assessed by an in vitro model represented by a 3D human osteoblast-osteoclast co-culture. It has been reported that the effects of ASCs are predominantly attributable to the paracrine effects of their secreted factors, that are present as soluble factors or loaded into extracellular vesicles.
