Multiresolution spatiotemporal mechanical model of the heart as a prior to constrain the solution for 4D models of the heart. [PDF]
, 2019 In several nuclear cardiac imaging applications (SPECT and PET), images are formed by reconstructing tomographic data using an iterative reconstruction algorithm with corrections for physical factors involved in the imaging detection process and with ...

Advanced Science, EarlyView.Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

CD11b+CD43hiLy6Clo splenocyte‐derived macrophages exacerbate liver fibrosis via spleen–liver axis
Hepatology, EarlyView., 2022 A population of splenic monocytes migrate into the liver and shift to macrophages, which account for the exacerbation of liver fibrosis. Abstract Background and Aims Monocyte‐derived macrophages (MoMFs), a dominant population of hepatic macrophages under inflammation, play a crucial role in liver fibrosis progression.

Journal of Cardiovascular Magnetic Resonance, 2019 Background Both ischemic and non-ischemic heart disease can cause disturbances in the myocardial blood volume (MBV), myocardial perfusion and the myocardial extracellular volume fraction (ECV). Recent studies suggest that native myocardial T1 mapping can

Noninvasive stress testing of myocardial perfusion defects: head-to-head comparison of thallium-201 SPECT to MRI perfusion [PDF]
, 2018 Background: To evaluate the diagnostic value of magnetic resonance imaging (MRI) of myocardial perfusion in the assessment of flow-limiting epicardial stenosis in a head-to-head comparison with abnormal thallium-201 (201TI) single photon emission ...

Prognostic implications of myocardial perfusion imaging and coronary calcium score in a Macedonian cohort of asymptomatic patients with type 2 diabetes [PDF]
, 2017 Aim: Type 2 diabetes is a risk factor for coronary artery disease; however, a number of studies have shown that patients are asymptomatic for coronary artery disease.

Advanced Science, EarlyView.This study revealed that E50K mutant microglia drive retinal peripapillary vascular density reduction in NTG via the Rpl17/Stat5b/Apoa1 axis and identified Apoa1 as a novel suppressor of retinal vascular endothelial cells. These findings identify a potential therapeutic target for glaucoma and support the clinical potential of EA for protecting RGCs ...

Targeting Histamine H4 Receptor in the Rostral Ventromedial Medulla to Relieve Hypertension
Advanced Science, EarlyView.H4R and its downstream TRPV1 channel mediate the excitatory effect of TMN histaminergic afferent inputs on GABAergic sympathoinhibitory neurons in RVMM. Intranasal delivery of selective H4R agonist VUF 8430 suppresses renal sympathetic outflow and elicits sustained depressor and bradycardia responses in SHRs and CUMS‐induced hypertensive rats ...
