Background: Peripapillary blood flow is of diagnostic value in glaucoma.
Material And Methods: We investigated the reproducibility of peripapillary blood flow measurements in healthy individuals and in open-angle glaucoma (OAG) patients with the Nidek laser speckle flowgraphy (LSFG)-NAVI system. Blood flow was calculated as the mean of vascular area (MV), mean of tissue area (MT), and mean of overall flow (MA).
Purpose: Autophagy is an important adaptive process for mechanotransduction, in which Damage-Regulated Autophagy Modulator 1 (DRAM1) has a key function in cell fate determination. This study aimed to analyze the influence of biomechanical loading on DRAM1 expression in periodontal cells and tissues.
Methods: Human periodontal ligament (PDL) fibroblasts were stimulated with different pressure protocols, physiological load and overload, in the presence and absence of autophagy inhibitor 3-methyladenine (3-MA) and compared with untreated cells.
Article Synopsis
- This study compares the image quality and methods for measuring infarct size between a new technique called MT-FIDDLE and the standard bright-blood LGE cardiac MRI in patients who had a heart attack (STEMI).
- The results indicate that MT-FIDDLE provides significantly better subjective image quality, particularly in terms of confidence for infarct segmentation and blood-pool contrast, with a high concordance in infarct volume measurements compared to bright-blood LGE.
- Ultimately, MT-FIDDLE proved to enhance the ability to differentiate between heart injury (myocardial infarction) and surrounding blood, suggesting it could be a superior imaging method for assessing heart damage after a STEMI.
Background: The presence and clinical significance of hepatic tissue alterations as assessed by cardiac magnetic resonance imaging in patients with ST-segment-elevation myocardial infarction (STEMI), are unclear. This study aimed to investigate associations of hepatic T1 patterns with myocardial tissue damage and clinical outcomes in patients suffering from STEMI.
Methods: We analyzed 485 patients with STEMI treated with percutaneous coronary intervention who were enrolled in the prospective MARINA STEMI study (Magnetic Resonance Imaging In Acute ST-Elevation Myocardial Infarction).
: Decreased cerebral oximetry (rSO) in cardiac surgery is associated with postoperative delirium (POD). However, interventions optimizing intraoperative rSO are inconclusive. : In this prospective observational cohort study, the relationship between rSO, middle cerebral artery blood flow velocity (MCAV), and processed EEG was assessed in cardiac surgery patients with and without POD.
