Ejection fraction is commonly used to assess Duchenne muscular dystrophy-associated cardiomyopathy (DMDAC), but it may remain normal (wrongly) despite significant myocardial dysfunction in patients. Therefore, better indicators of myocardial dysfunction are needed for longitudinal (with time) assessment and treatment of DMDAC patients. This study evaluates non-invasive LV PV loop-derived elastance, contractility and efficiency in relation to EF for patients developing DMDAC.

Objective: Study of neuroimaging changes according to MRI morphometry and their comparison with the structure and severity of cognitive impairment (CI) in patients with Alzheimer's disease (AD) and primary open-angle glaucoma (POAG).
Material And Methods: The study involved 90 patients who were divided into two equal groups of 45 people and who early had diagnosis of AD (group 1; median age - 71 [66; 77] years) and POAG (group 2; median age - 68 [64; 77] years). 71] years).

Background: Facial prosthetics are an important means to rehabilitate patients with congenital or acquired facial defects. However, with a time-consuming manual workflow and workforce shortage, access to facial prosthetics is limited in Australia and worldwide, especially for rural and remote patients. Optical 3D scanning has been increasingly integrated in digitizing data.

Increased telomerase activity has been considered as a conspicuous sign of human cancers. The catalytic cores of telomerase involve a reverse transcriptase and the human telomerase RNA (hTR). However, current detection of telomerase is largely limited to its activity at the tissue and single-cell levels.

Optical coherence tomography angiography (OCT-A) is one of the imaging method that enables visualization of tumor vessels.
Purpose: This article examines the features of angioarchitecture, vascular network density, and perfusion density of iris melanoma and progressive iris nevus using OCT-A.
