Implementing specialised vestibular physiotherapy in an emergency department: a process evaluation.

Background: Dizziness and vertigo-like symptoms, often caused by common peripheral vestibular disorders such as benign paroxysmal positional vertigo (BPPV), may significantly impact function and quality of life. These symptoms often result in emergency department (ED) presentations. Evidence-based clinical practice guidelines strongly recommend using physical assessment and treatment manoeuvres for the assessment, diagnosis and treatment of these symptoms.

Physical integrity of smooth muscle myosin filaments is enhanced by phosphorylation of the regulatory myosin light chain.

Background And Aims: Smooth muscle myosin monomers self-assemble in solution to form filaments. Phosphorylation of the 20-kD regulatory myosin light chain (MLC20) enhances filament formation. It is not known whether the phosphorylated and non-phosphorylated filaments possess the same structural integrity.
