Comparative effect of various drugs upon the coronary circulation

open access: yesJournal of Physiology, 1927
IN a series of recent papers(1,2,3) a method has been developed for registering the outflow of blood from the drained coronary sinus during a single cardiac cycle by means of the hot-wire anemometer. The records already obtained by this method show three

Ischemic Myocardium Targeting Peptide‐Guided Nanobubbles for Multimodal Imaging and Treatment of Coronary Microvascular Dysfunction

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanobubbles functionalized with indocyanine green and ischemic myocardium‐targeting peptide effectively target cardiomyocytes and enable the multimodal (fluorescence, ultrasonic, and photoacoustic) imaging of ischemic myocardium in mice with coronary microvascular dysfunction (CMD).

Network-Based Approach for Modeling and Analyzing Coronary Angiography [PDF]

open access: yes, 2019
Significant intra-observer and inter-observer variability in the interpretation of coronary angiograms are reported. This variability is in part due to the common practices that rely on performing visual inspections by specialists (e.g., the thickness of coronaries). Quantitative Coronary Angiography (QCA) approaches are emerging to minimize observer's

Coronary artery fistulae : 4 cases repaired surgically [PDF]

open access: yes, 2015
Coronary artery fistulae involve a communication between a coronary artery and a heart chamber or part of the pulmonary circulation. Most are asymptomatic and discovered incidentally, whilst larger ones may cause coronary steal syndrome. Fistulae may

Rupture of the arterial wall causes deflection in pressure time course during ex vivo balloon angioplasty [PDF]

open access: yes, 1997
A relation between restenosis and arterial lesions resulting from balloon angioplasty has been suggested in literature. Nevertheless, it is unclear to what extent angioplasty-induced arterial wall lesions contribute to the occurrence of restenosis.

Inorganic Nanomaterials Meet the Immune System: An Intricate Balance

open access: yesAdvanced Healthcare Materials, EarlyView.
Metal nanomaterials influence the immune responses, such as cytokine production and T‐cell activity. Unintended immune modulation can have significant consequences while its fine‐tuning may transform the oncology care. Within this review, a critical analysis is offered regarding the nano/immune‐interaction and suggests the future research directions to

Imaging of the calcium activated potassium channel 3.1 (KCa3.1) in vivo using a senicapoc‐derived positron emission tomography tracer

open access: yesArchiv der Pharmazie, Volume 355, Issue 12, December 2022., 2022
The 18F‐labeled derivative [18F]3 of senicapoc was synthesized using the prosthetic group approach with 1‐azido‐2‐[18F]fluoroethane ([18F]6) in a “click” reaction. The biological activity of the new positron emission tomography tracer was evaluated in vitro and in vivo.

Hyper Association Graph Matching with Uncertainty Quantification for Coronary Artery Semantic Labeling [PDF]

open access: yesarXiv, 2023
Coronary artery disease (CAD) is one of the primary causes leading to death worldwide. Accurate extraction of individual arterial branches on invasive coronary angiograms (ICA) is important for stenosis detection and CAD diagnosis. However, deep learning-based models face challenges in generating semantic segmentation for coronary arteries due to the ...

Regulation of Coronary Blood Flow [PDF]

open access: yes, 2017
The heart is uniquely responsible for providing its own blood supply through the coronary circulation. Regulation of coronary blood flow is quite complex and, after over 100 years of dedicated research, is understood to be dictated through multiple ...

Functionalized Cerium Oxide Nanoparticles Enhance Penetration into Melanoma Spheroids In Vivo through Angiogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.
