The effects of severe plastic deformation (SPD) by means of high-pressure torsion (HPT) on the structural properties of the two iron-based metallic glasses FeCuNbSiB and FeCoSiBPCu have been investigated and compared. While for FeCuNbSiB, HPT processing allows us to extend the known consolidation and deformation ranges, HPT processing of FeCoSiBPCu for the first time ever achieves consolidation and deformation with a minimum number of cracks. Using numerous analyses such as X-ray diffraction, dynamic mechanical analyses, and differential scanning calorimetry, as well as optical and transmission electron microscopy, clearly reveals that FeCoSiBPCu exhibits HPT-induced crystallization phenomena, while FeCuNbSiB does not crystallize even at the highest HPT-deformation degrees applied. The reasons for these findings are discussed in terms of differences in the deformation energies expended, and the number and composition of the individual crystalline phases formed. The results appear promising for obtaining improved magnetic properties of glassy alloys without additional thermal treatment.

Repositioning the Posterior Septal Angle in Rhinoplasty: Methods and Outcomes.

Beckman Laser Institute & Medical Clinic, University of California - Irvine, Irvine, California, U.S.A.
Objective: Repositioning and fixation of the posterior septal angle (PSA) relative to the anterior nasal spine (ANS) is a well-known maneuver performed during rhinoplasty. Suture techniques through the periosteum along with transosseous drilling through the spine are the two most common fixation methods. We report on how nasal airway patency varies as a function of technique and patient demographic factors.

Full-arch implant rehabilitation in extremely atrophic edentulous mandibles is still challenging due to the high risk of fracture and the limited bone availability. The approach proposes using short implants with immediate loading for final prostheses as a treatment option, which offers shorter treatment times and fewer invasive procedures. A 66-year-old female patient with an edentulous mandible and severe alveolar bone resorption was treated with four short implants in the interforaminal area.

Background: Hypertrophic scar (HS) is a fibroproliferative disorder resulting from abnormal healing of skin tissue after injury. Although various therapies are currently employed in clinical to treat HSs, there is no widely accepted standard therapy. Micro-plasma radiofrequency (MPR) and autologous chyle fat grafting are emerging treatments for this condition, and they have demonstrated promising therapeutic outcomes in clinical applications.

With the growing demand for aesthetic enhancements, particularly filler injections for nasolabial folds (NLFs), there is a need for more objective and quantitative assessment methods beyond the traditional subjective scales like the Wrinkle Severity Rating Scale (WSRS). This study introduces a novel evaluation method combining 3-dimensional (3D) imaging and grayscale analysis to objectively assess NLF severity and treatment outcomes. A total of 100 healthy participants (86 females, 14 males; mean age 41.
