Published: July 2020

Here we propose that the upper bound marginal stability of proteins is a universal property that includes macro-molecular complexes and is not affected by molecular changes such as mutations and post-translational modifications. We theorize that its existence is a consequence of Afinsen's thermodynamic hypothesis rather than a result of an evolutionary process. This result enables us to conjecture that neutral evolution should also be, with respect to protein stability, a universal phenomenon.

Stabilised hyaluronic acid gel marker versus surgical clips for tumour bed delineation in breast cancer radiotherapy using MRI-simulation.

Radiother Oncol

January 2025

Department of Radiation Oncology Olivia Newton-John Cancer Wellness & Research Centre Austin Health Victoria Australia; Department of Medical Imaging and Radiation Sciences, Monash University Clayton Victoria Australia; Genesis Care, Ringwood Private Hospital Victoria Australia.

Background And Purpose: Compare breast cancer tumour bed (TB) delineation using stabilised hyaluronic acid (sHA) gel and MRI-simulation versus surgical clips and CT-simulation within same patient cohort.

Materials And Methods: Prospective single arm study of patients undergoing breast conserving surgery. Patients had both clips (≥5) and sHA gel markers inserted to define the TB and underwent MRI and CT simulation scans.

Objectives: To investigate whether extractions in adult anterior openbite (AOB) patients lead to improved treatment outcomes and better short-term stability.

Materials And Methods: Records of extraction (EXT) and nonextraction (NE) adult patients were identified from all patients treated with fixed appliances through the National Dental Practice-Based Research Network. Photographic Openbite Severity Index was used to assess treatment success and stability.

Objective: This case report presents the interdisciplinary retreatment of a patient with a worn full-mouth rehabilitation using defect-oriented restorations, horizontal preparations, and vertical dimension of occlusion (VDO) increase.

Clinical Considerations: A 58-year-old woman with a previous full-mouth rehabilitation presented with worn dentition, loss of VDO, and reduced posterior support. Examination revealed signs of parafunctional habits, tetracycline-stained teeth, and compromised aesthetics with exposed discolored teeth and open embrasure spaces.

Aim: To assess hard as well as soft peri-implant tissues within cases having two lost adjacent anterior teeth treated through placing either two implants with two separate crowns or only an implant along with a crown with a cantilever, and evaluating the effect of polyetheretherketone (PEEK) restoration on cantilever design up to 18 months after functional loading.

Materials And Methods: Twenty-seven participants (15 males and 12 females; mean age, 38.6 years; range 20-50 years) with missing two adjacent anterior teeth were treated with implant system (Flotecno implant system, Italy).

Introduction: Aging-related deficits in the physiological properties of skeletal muscles limit the control of dynamic stability during walking. However, the specific causal relationships between these factors remain unclear. This study evaluated the effects of aging-related deficits in muscle properties on dynamic stability during walking.
