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.

A Three-dimensional Printed Low-cost Anterior Shoulder Dislocation Model for Ultrasound-guided Injection Training. [PDF]

, 2018
Anterior shoulder dislocations are the most common, large joint dislocations that present to the emergency department (ED). Numerous studies support the use of intraarticular local anesthetic injections for the safe, effective, and time-saving reduction ...

Posterior dislocation of the sternoclavicular joint

Radiology Case Reports, 2011
Posterior dislocation of the sternoclavicular joint is a rare but serious and life-threatening injury. Case reports describing injury to mediastinal structures including the trachea, esophagus, and the great vessels from posterior displacement of the medial clavicle (1, 2, 3, 4, 5, 6) have been discussed in the literature.

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.

Sequelae of subtalar joint dislocations at two level 1 trauma centers: A case series and literature review

Foot & Ankle Surgery: Techniques, Reports & Cases, 2022
Traumatic incidences of subtalar joint dislocations are rare, occurring in approximately less than 1% of all traumatic dislocations. These injuries, however, often require prompt treatment due to involvement of skin tenting, open injury, and/or ...

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

Towards the grain boundary phonon scattering problem: an evidence for a low-temperature crossover

, 1998
The problem of phonon scattering by grain boundaries is studied within the wedge disclination dipole (WDD) model. It is shown that a specific q-dependence of the phonon mean free path for biaxial WDD results in a low-temperature crossover of the thermal ...

Powder Metallurgy Preparation of Metastable β Ti–Cr–Ge Alloys for Medical Applications

Advanced Engineering Materials, EarlyView.
This study develops metastable β Ti–Cr–Ge alloys using powder metallurgy for biomedical implants. The Ti–10Cr–2Ge alloy exhibits superior mechanical performance with high yield strength (>1100 MPa), low Young's modulus (<85 GPa), and excellent strain hardening behavior.

Effect of solute atoms on dislocation motion in Mg: an electronic structure perspective. [PDF]

, 2015
Solution strengthening is a well-known approach to tailoring the mechanical properties of structural alloys. Ultimately, the properties of the dislocation/solute interaction are rooted in the electronic structure of the alloy. Accordingly, we compute the

Study of the Effect of Process Parameters and Heat Treatment on the Formation and Evolution of Directed Energy Deposition of IN718‐CuCrZr Interface

Advanced Engineering Materials, EarlyView.
Bimetallic structures of Inconel 718 and CuCrZr are fabricated using the laser powder directed energy deposition method. The study reveals a strong dependence of interface characteristics such as width and interfusion on processing and heat treatment strategies.
