Highly porous polycaprolactone microspheres for skeletal repair promote a mature bone cell phenotype .

J Mater Chem B

November 2024

Department of Materials Science and Engineering, The Kroto Research Institute, University of Sheffield, Sheffield, UK.

Article Synopsis
  • The study focuses on creating new biomaterials, specifically degradable polymer microparticles, to improve treatments for skeletal defects.* -
  • Researchers developed round polycaprolactone-based microspheres that support bone cell growth for 30 days and enable the deposition of a bone-like extracellular matrix.* -
  • These microspheres show greater potential as bone graft substitutes due to enhanced cell survival and differentiation, which could lead to better outcomes in bone repair.*

An advanced in silico model of the oral mucosa reveals the impact of extracellular spaces on chemical permeation.

Int J Pharm

December 2024

Department of Mathematical Sciences, University of Liverpool, Liverpool L69 7ZL, United Kingdom; Department of Mathematics, King's College London, London WC2R 2LS, United Kingdom.

Accurately predicting the permeation of chemicals through human epithelial tissues is crucial for pharmaceutical therapeutic design and toxicology. Current mathematical models of multi-layered stratified squamous epithelium such as those in the oral cavity use simplistic 'bricks and mortar' geometries that do not fully account for the complex cellular architecture that may affect chemical permeation in these tissues. Here we aimed to develop a new, advanced mechanistic mathematical model of the human epithelium that more accurately represents chemical tissue permeation.

  • The study investigates the connection between the olfactory system and COVID-19 symptoms like loss of smell (anosmia) and taste (hypogeusia) by examining the role of the nervus terminalis (NT) using ultra-high-field 7T MRI imaging.
  • Researchers evaluated brain images from 45 COVID-19 patients and 29 healthy controls to identify the presence of NT, olfactory bulbs (OB), and signs of brain volume loss or changes in signal intensity.
  • The results showed that NT was visible in all participants, with COVID-19 patients experiencing anosmia or hypogeusia showing significant T2 hyperintensity in NT, OB, and olfactory tract (OT) compared to controls and

Approximately one in five individuals experience alveolar osteitis (AO) following wisdom tooth extraction. AO is characterised by loss of the blood clot from the tooth extraction socket leading to infection and pain, resulting in repeated hospital visits that impose a substantial burden on healthcare systems. Current treatments are sub-optimal; to address this we developed a novel drug-loaded mucoadhesive patch composed of dual electrospun polyvinyl pyrrolidone/Eudragit RS100 (PVP/RS100) and poly(N-isopropylacrylamide) (PNIPAM) fibres protected by a poly(ε-caprolactone) (PCL) backing layer.

A Tissue-Engineered Model of T-Cell-Mediated Oral Mucosal Inflammatory Disease.

J Invest Dermatol

October 2024

School of Clinical Dentistry, University of Sheffield, Sheffield, United Kingdom; Insigneo Institute, University of Sheffield, Sheffield, United Kingdom.

Article Synopsis
  • Scientists developed a tissue-engineered model of oral mucosa to study oral lichen planus (OLP) and its inflammatory properties, addressing the lack of experimental models for this condition.
  • They used activated T-cells to simulate OLP pathogenesis, resulting in increased secretion of inflammatory substances and tissue damage, which was assessed through histological analysis.
  • The study tested treatment options such as JAK inhibitors and clobetasol, showing potential for these methods to reduce cytokine release and prevent tissue damage, paving the way for future therapeutic research.

Introduction: The incidence of Central Nervous System (CNS) disorders, including Parkinson's disease, Alzheimer's disease, stroke, and malignancies, has risen significantly in recent decades, contributing to millions of deaths annually. Efficacious treatment of these disorders requires medicines targeting the brain. The Blood-Brain Barrier (BBB) poses a formidable challenge to effective drug delivery to the brain, hindering progress in CNS therapeutics.

Article Synopsis
  • The study addresses the challenges of placing dental implants correctly due to different shapes of the mandible, which can lead to complications like lingual perforations.
  • By analyzing 96 cone-beam CT images, researchers classified mandibular shapes into U, C, and P types, finding that U-shaped mandibles are the most prone to perforations.
  • The results showed U, P, and C shapes appear in 34.6%, 28.9%, and 36.5% of cases respectively, with significant differences in shape related to gender, age, and tooth type, highlighting the importance of understanding these anatomical variations for safer dental procedures.
