Anatomy of the heart : axial slice with chambers, myocardium, pericardium, left and right coronary arteries and other structures labeled. Anatomy of the human heart and coronaries: how to view anatomical structures This tool provides access to an MDCT atlas in the 4 usual planes, allowing the...
A variation on the theme, the clinical syndrome labeled cholesterol embolization, with small atherosclerotic particles obstructing small arteries, is a rare complication of severe aortic atherosclerosis. Clinical signs include mottled skin and "purple toes" in the lower extremities together with renal insu...

1A) was employed to visualize the distribution of myosin light chain phosphorylation (MLC-p) and SM-α-actin in relation to phalloidin labeled actin filaments in SCAs under a stable level of myogenic tone (Fig. 1B,C). A longitudinal circumferential view of the vessel wall (outer layer view...
Cholesterol esterifying activity, measured with 14C-labeled fatty acids, was fairly low in coronary arteries, but considerable activity was present in heart tissue. Oleic acid substrate esterified cholesterol most effectively, followed by linoleic and elaidic acid. Under the incubation conditions for ...
Pairing the SV/atria portion of transgenic hearts with wild-type (WT) ven- tricle gave rise to labeled coronary ECs on the ventricle surface only in the presence of tamoxifen. As a control, the above pairing did not lead to labeled coronary ECs if tamoxifen was not added (Figure 4A). ...
Resting heart rate, cardiac output, and left atrial and aortic pressures were evaluated before and during a 1-min LCf occlusion. Myocardial blood flow was also measured with radioactively-labeled microspheres injected into the left atrium during the LCf occlusion. Subsequently the dogs were exercised...
Blood flow and pressure calculated using the currently available methods have shown the potential to predict the progression of pathology, guide treatment strategies and help with postoperative recovery. However, the conspicuous disadvantage of these met
in a transgenic CAA type 1 rat model. We discovered that, in CAA, CSF moves more rapidly along the periarterial spaces that serve as influx routes to the glymphatic system. The observation of high-speed CSF flow currents in CAA was unexpected given the build-up of microvascular Aβ. ...
The preferential accumulation of vascular smooth muscle cells (vSMCs) on arteries versus veins during early development is a well-described phenomenon, but the molecular pathways underlying this polarization are not well understood. In zebrafish, the cxc
