Development of Collateral Circulation in Partially Devascularized Feline Sciatic Nerve
A survey of the existing literature in the field of peripheral nerve vascularity has established that nerve function is influenced by vascular supply; however, opinion varies considerably concerning the extent of such dependence. Apparently, influence of vascular supply is unquestioned; its …

The role of fibroblast growth factor-2 (FGF2) in vascular remodeling and adaptation
… that vessel responsiveness is altered in the collateral circulation of the ischemic Fgf2⁻/⁻ limb. This possible identification of FGF2 as a "functional" factor in the collateral circulation suggests a novel, non-mitogenic role for endogenous growth factors. Finally, Fgf2⁻/⁻ mice had altered …

Barbiturate treatment in experimental transient focal cerebral ischaemia
… occlusion and this bloodflow is provided by the collateral circulation. Thus, whether infarction results and the extent of it, becomes a factor of the period of ischaemia and the collateral circulation present. Dujovny et al (1976), Morawetz et al (1978), Ojeman et al (1979), Kieck and Crowell …

ΣΥΓΚΡΙΤΙΚΗ ΜΕΛΕΤΗ ΤΗΣ ΑΟΡΤΟΓΡΑΦΙΑΣ ΚΑΙ ΤΗΣ ΡΑΔΙΟΙΣΟΤΟΠΙΚΗΣ ΥΠΟΛΟΓΙΣΤΙΚΗΣ ΑΓΓΕΙΟΓΡΑΦΙΑΣ (Ρ.Υ.Α.) ΣΤΗΝ ΑΟΡΤΟΛΑΓΟΝΙΟ ΝΟΣΟ
… ANGIOGRAPHY IS BETTER IN SHOWING THE DEGREE OF COLLATERAL CIRCULATION. B. QUANTITATIVE RESULTS: IN ORDER TO ESTIMATE THE QUANTITATIVE RESULTS, WE DEVELOPED A NEW SOFTWARE PROGRAM APPLIED IN MICROCOMPUTER WITH HIGH RESOLUTION GRAPHICS. THE PROGRAM MEASURED SEMIAUTOMATICALLY TWO BLOOD …

Sex Differences in Collateral Remodeling Following Hindlimb Arterial Occlusion
… tissue injury can be naturally mitigated by the collateral circulation, improving patient prognosis. Previous sex-comparison studies describing differences in vascular remodeling are inconsistent. Therefore, the aim of this study was to describe the effect of arterial occlusion on collateral …

Η ΑΠΟΛΙΝΩΣΗ ΤΗΣ ΕΞΩ ΚΑΡΩΤΙΔΑΣ ΣΤΟΝ ΑΝΘΡΩΠΟ ΣΕ ΑΙΜΟΡΡΑΓΙΕΣ ΤΩΝ ΚΛΑΔΩΝ ΤΗΣ
… ASCERTAIN WHETHER THE INTERRUPTION OF THE BLOOD CIRCULATION IN THE EXTERNAL CAROTID A. CONTRIBUTES TO THE CONTROL OF HEMORRHAGE RESULTING FROM A BRANCH OF THIS ARTERY. THIS WAS STUDIED ON 6 MONGREL DOGS ON WHICH WERE SURGICALLY PREPARED THE COMMON AND THE EXTERNAL CAROTID ARTERIES, THE …

Biomechanical regulation of arteriogenesis : defining critical endothelial-dependent events
… remodeling process in which pre-existing collateral arterioles remodel to form large diameter conductance arteries, has received recent attention for its therapeutic potential in treating CHD, but the mechanisms regulating the process remain incompletely understood. In particular, little …

The Impacts of Arterial Occlusion, Sex, and Exercise on Arteriogenesis and Functional Vasodilation
… systemic impairments in vasodilation, but as the collateral circulation is the primary site of resistance to the ischemic zone, impaired collateral vasodilation would have the greatest potential to induce claudication. Collateral function following arterial occlusion is not well defined, but …

Modeling oxygen requirements in ischemic cardiomyocytes
… This level of oxygen could be achieved through collateral circulation. This model of ischemia will also provide future investigations of the reperfusion process to proceed from a known metabolic and molecular state of the cardiomyocytes preceding re-oxygenation.

INVESTIGATION OF GENETIC FACTORS DETERMINING ISCHEMIC STROKE OUTCOME
… of infarct volume, the extent of native collateral circulation and neuroprotection. Using the infarct volume screening panel from 32 inbred strains, we observed that infarct volume is inversely correlated with the native collateral vessel number. However, among these inbred strains, we …

Effekte von Leptin- und MCP-1-Applikation auf funktionelle Parameter der Arteriogenese : eine experimentelle Studie mittels Ultraschallflussmessungen, Mikrosphärperfusion und Proliferationsanalyse
Untersuchungen zur Stimulation des Gefäßwachstums sind seit einigen Jahren Gegenstand intensiver Forschung. Die Methoden zur Erfassung einer verbesserten Gewebsperfusion variieren jedoch beträchtlich. Die verlässliche Erfassung der Arteriogenese ist die wesentliche Voraussetzung bei der Auswahl …
