Priority Musculoskeletal Health Research Questions for People With Generalized Joint Hypermobility: An International Delphi Study

Arthritis Care &Research, EarlyView.
Objective This study aimed to identify the top 10 international research priorities for musculoskeletal health of people with generalized joint hypermobility. Methods A three‐round Delphi method using an online survey was implemented. Three participant stakeholder groups were eligible for inclusion: (1) people with lived experience of joint ...

Simultaneous Volar and Dorsal Dislocation of Proximal Inter Phalangeal Joints in Adjacent Fingers - A Case Report

Indian Journal of Plastic Surgery, 1994
Volar dislocation of PIP joint or MCP joint is a rare injury. They are seldom seen acutely and hence literature is sparse on the ideal method of management of these injuries. We had a patient who presented with a rare combination of volar dislocations of

Dislocation climb models from atomistic scheme to dislocation dynamics [PDF]

, 2016
We develop a mesoscopic dislocation dynamics model for vacancy-assisted dislocation climb by upscalings from a stochastic model on the atomistic scale. Our models incorporate microscopic mechanisms of (i) bulk diffusion of vacancies, (ii) vacancy exchange dynamics between bulk and dislocation core, (iii) vacancy pipe diffusion along the dislocation ...

Elastic vs. plastic strain relaxation in coalesced GaN nanowires: an x-ray diffraction study [PDF]

Phys. Rev. Applied 6, 064023 (2016), 2016
The coalescence in dense arrays of spontaneously formed GaN nanowires proceeds by bundling: adjacent nanowires bend and merge at their top, thus reducing their surface energy at the expense of the elastic energy of bending. We give a theoretical description of the energetics of this bundling process.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Determining the Necessity of Post‐Processing Heat Treatment for the 316L Stainless Steel Manufactured by Laser Powder Bed Fusion through Evaluation of Mechanical and Corrosion Properties

Advanced Engineering Materials, EarlyView.
This article examines the effect of postprocessing heat treatment on 316L stainless steel (SS316L) produced via laser powder bed fusion (LPBF). Heat treatment slightly affects property anisotropy, reduces strength, and enhances elongation. However, it increases corrosion susceptibility due to nanoscale precipitations, though overall corrosion ...

Bilateral Asymmetrical Hip Dislocation in a 70-year-old Female: A Rare Case Report

Journal of Orthopedics, Traumatology and Rehabilitation
Traumatic dislocation of the hip joint is a rare injury representing 2%–5% of all dislocations while bilateral hip dislocation accounts for 1.25% of all hip dislocations.

New Mechanics of Spinal Injury [PDF]

, 2008
The prediction and prevention of spinal injury is an important aspect of preventive health science. The spine, or vertebral column, represents a chain of 26 movable vertebral bodies, joint together by transversal viscoelastic intervertebral discs and longitudinal elastic tendons. This paper proposes a new locally-coupled loading-rate hypothesis}, which

Non‐Destructive and Mechanical Characterization of the Bond Quality of Co‐Extruded Titanium‐Aluminum Profiles

Advanced Engineering Materials, EarlyView.
This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Dislocation nucleation and vacancy formation during high-speed deformation of fcc metals [PDF]

Philos. Mag. Lett. 81, 301-309 (2001), 2000
Recently, a dislocation free deformation mechanism was proposed by Kiritani et al., based on a series of experiments where thin foils of fcc metals were deformed at very high strain rates. In the experimental study, they observed a large density of stacking fault tetrahedra, but very low dislocation densities in the foils after deformation.
