X-ray diffraction and X-ray tomography are performed on intermetallic particles undergoing lithiation in a porous electrode. Differences between ensemble phase evolution and that at a single-particle level are explored. It is found that all particles evidence core-shell lithiation; however, particles with internal porosity are more mechanically robust and exhibit less fracture.

Crispant analysis in zebrafish as a tool for rapid functional screening of disease-causing genes for bone fragility.

Heritable fragile bone disorders (FBDs), ranging from multifactorial to rare monogenic conditions, are characterized by an elevated fracture risk. Validating causative genes and understanding their mechanisms remain challenging. We assessed a semi-high throughput zebrafish screening platform for rapid in vivo functional testing of candidate FBD genes.

Objective: To assess the prevalence of changes on computed tomography (CT) in Graves' orbitopathy (GO) and to correlate those changes with disease activity, as well as with clinical and biochemical variables.
Materials And Methods: This was a retrospective study, conducted at a tertiary hospital, of clinical, biochemical, and imaging data from consecutive patients with GO who underwent at least one orbital CT scan between July 2012 and December 2020. A single observer quantified the thickness of the extraocular muscles and the degree of proptosis.

Anterior lumbar interbody fusion (ALIF) is an anterior surgical approach for interbody fusion in the lumbar spine which affords the surgeon unfettered access to the disc space and allows for release of the anterior longitudinal ligament and insertion of a large, lordotic interbody graft. Despite the benefits associated with ALIF when compared with other lumbar interbody fusion techniques, the ALIF approach is associated with a number of unique complications, and certain patient-specific criteria (e.g.

Atlantoaxial rotatory subluxation (AARS) in the adult population is primarily trauma-induced. Conservative and surgical treatments have both been used successfully in treating AARS. In cases where AARS cannot be reduced by conservative measures, open reduction and fusion is the conventional treatment approach.

Background: The objective of this report is to present a case of two cervical spine artificial discs (Bryan Cervical Disk) that completely disappeared within 6 months as a result of a high-energy trauma more than 10 years after the initial surgery. Implant dislocation is a known complication in artificial cervical disc replacement. However, this report presents the case of an exceptional migration path with esophageal ingrowth and rectal excretion, not only for one artificial disc but for two at different times It highlights the need for long-term follow-up examinations after artificial cervical disc arthroplasty (ACDA).
