Challenges in Micro-CT Characterization of Composites

, 2019
Studies related to defect investigation of composite materials with x-ray-based micro-computed tomography (micro-CT) mostly focus on the void presence inside materials and its impact on the mechanical behavior of composites. This chapter focuses on the localization and the quantitative investigation of processing related anomalies like pore formation ...

Metronidazole‐Loaded Cyclodextrin Nanogels for Antibacterial Therapy and Microbiota Regulation in Periodontitis

Advanced Healthcare Materials, EarlyView.
A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Vitamin C Prevents Hypogonadal Bone Loss [PDF]

, 2012
Epidemiologic studies correlate low vitamin C intake with bone loss. The genetic deletion of enzymes involved in de novo vitamin C synthesis in mice, likewise, causes severe osteoporosis. However, very few studies have evaluated a protective role of this

An Ultra‐Flexible Neural Electrode with Bioelectromechanical Compatibility and Brain Micromotion Detection

Advanced Healthcare Materials, EarlyView.
Neural electrodes face a mechanical mismatch with brain tissue. This study proposes a bioelectromechanical coupling strategy using an ultra‐flexible electrode designed for synchronized motion. Optimized to match brain tissue stiffness, it achieves dual signal acquisition and micromotion sensing, with characterized interfacial forces and piezoresistive ...

Automated region growing-based segmentation for trabecular bone structure in fresh-frozen human wrist specimens

BMC Medical Imaging
Bone strength depends on both mineral content and bone structure. Measurements of bone microstructure on specimens can be performed by micro-CT. In vivo measurements are reliably performed by high-resolution peripheral computed tomography (HR-pQCT) using

Spherical Skin Model: Stratified Co‐Culture of Fibroblasts and Keratinocytes on Spherical Beads Toward Compound Screening

Advanced Healthcare Materials, EarlyView.
Models of the human skin must combine the relevant biological contents and suitable biomaterials with the correct spatial organization. Performing compound screening on such in vitro models also requires fast and reproducible production methods of the models.
