Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1206-1218, September 2026.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Review on Dynamic Contour Tonometry and Ocular Pulse Amplitude

open access: yes, 2016
Intraocular pressure (IOP) measurement is the cornerstone of the management of glaucoma patients. The gold standard for assessing IOP is Goldmann applanation tonometry (GAT). Recently, the dynamic contour tonometer (DCT) has become available.

Non‐Invasive Assessment of Endothelial Dysfunction and Arterial Stiffness in Fontan Circulation

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 9, September 2026.
The Fontan procedure is the definitive treatment for complex congenital heart disease, creating a circulation without a subpulmonary ventricle. This altered hemodynamic state negatively affects endothelial function, contributing to progressive organ dysfunction and long‐term morbidity.

Diagnóstico de tuberculose ocular

open access: yes, 2016
A tuberculose ocular continua sendo um diagnóstico clínico presuntivo, pois os testes padrão-ouro para diagnosticar a tuberculose ocular geralmente não são úteis: as culturas de Mycobacterium tuberculosis requerem semanas para serem processadas em meio ...

Functional Markers of Vascular Aging: Subendocardial Viability Ratio, Augmentation Pressure, and Augmentation Index as Links to Atherosclerotic Cardiovascular Disease Risk

open access: yesThe Journal of Clinical Hypertension, Volume 28, Issue 9, September 2026.
ABSTRACT This study investigated the correlation of functional hemodynamic parameters, including subendocardial viability ratio (SEVR), augmentation pressure (AP) and heart‐rate‐corrected augmentation index (Aix@75), with age and atherosclerotic cardiovascular disease (ASCVD) risk in a Chinese population.
