A critical comparison of methods for the determination of the ageing sensitivity in biomedical grade yttria stabilized zirconia [PDF]
Journal of Biomedical Materials Research 72(2), 239-245 (2005), 2017 Since the recent failure events of two particular series of zirconia femoral heads for total hip replacement prosthesis, a large decrease in the use of zirconia ceramics for orthopaedic implants has been observed. In spite of the biomedical success of this material during the last ten years, this was required for safety reasons, until the cause of the ...

Advanced Healthcare Materials, EarlyView.Volumetric muscle loss (VML) due to trauma or surgery, often leads to physical impairments. Traditional treatments rely on autologous flaps, limited by muscle availability often leading to donor site morbidity. This study presents multimodal bioprinting as an innovative approach for fabricating vascularized muscle flaps with 3D‐printed macrovessels ...

Interleukin 6/gp130 axis promotes neural invasion in pancreatic cancer
Cancer Medicine, Volume 11, Issue 24, Page 5001-5012, December 2022., 2022 Nerve invasion (N‐inv) is an important prognostic factor in pancreatic ductal adenocarcinoma (PDAC). To elucidate circulating stimulators for nerve invasion, the authors evaluated the stimulant activity and the inhibitory effects of IL‐6/gp130 axis. Biological activity of IL‐6/gp130 axis promoted nerve invasion in murine model and was upregulated in ...

A Practical Framework for ROI Detection in Medical Images -- a case study for hip detection in anteroposterior pelvic radiographs [PDF]
arXiv, 2021 Purpose Automated detection of region of interest (ROI) is a critical step for many medical image applications such as heart ROIs detection in perfusion MRI images, lung boundary detection in chest X-rays, and femoral head detection in pelvic radiographs. Thus, we proposed a practical framework of ROIs detection in medical images, with a case study for

Clinical and Experimental Dental Research, Volume 8, Issue 6, Page 1331-1340, December 2022., 2022 Abstract Objectives Bone grafting is commonly used to reconstruct skeletal defects in the craniofacial region. Several bone augmentation models have been developed to evaluate bone formation using novel bone substitute materials. The aim of this study was to evaluate a surgical animal model for establishing a three‐dimensional (3D) grafting environment
