Highlights The article outlines the modern concept of arterial myocardial revascularization, presents most promising directions for development coronary surgery, and describes results prospects clinical application autogenous grafts using two internal thoracic arteries in various graft configuration situ, making it possible to assess effectiveness procedure. Abstract There are many approaches a...

Abstract Cerebrovascular diseases like atherosclerosis pose a great threat to health and wellbeing of people worldwide. To enable early diagnosis treatment gradually progressing occlusion the carotid arteries, we propose BODYTUNE system. Consisting custom-built auscultation device mobile application, it aims at enabling monitoring blood flow within arteries on regular basis home. In this work, ...

In helically-cut strips of cerebral arteries isolated from dogs, serotonin, tryptamine, 5-hydroxytryptophan and tryptophan caused a dose-related contraction. The potency was in the order of serotonin greater than tryptamine much greater than 5-hydroxytryptophan = tryptophan. In femoral arterial strips, only serotonin and tryptamine produced contractions. In cerebral arteries, the dose-response ...

The stability of arteries is essential to normal arterial functions and loss of stability can lead to arterial tortuosity and kinking. Collagen is a main extracellular matrix component that modulates the mechanical properties of arteries and collagen degradation at pathological conditions weakens the mechanical strength of arteries. However, the effects of collagen degradation on the mechanical...

OBJECTIVES To study the prevalence of arterial diseases in the arteries supplying the lumbar spine and their relation to other vascular diseases, as well as to chronic low back pain. METHODS Five pairs of the lumbar arteries and the middle sacral artery were evaluated from 140 postmortem aortograms, performed in connection with routine medicolegal necropsies on subjects ranging from 16 to 89 ...

Responses to K(+), endothelin-1 (ET-1), and acetylcholine (ACh) of isolated adrenal, femoral, middle cerebral, and renal arteries from fetal [110--145 days gestational age (dGA, term approximately 148 dGA)] and 0- to 24-h newborn (NB) lambs were evaluated using the technique of wire myography. Responses at distinct developmental ages for each vascular bed were compared. In all arteries sensitiv...

in patients requiring coronary artery bypass grafting (cabg), usually at least one of the internal mammary arteries is used. this study evaluates the degree of atherosclerotic involvement of the internal mammary artery (ima) in patients undergoing cabg. during two months period, 79 patients (66 male and 13 female with a medium age of 58 years) undergoing myocardial revascularization had a biops...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

Objective(s) Diabetes related dysfunction of resistance vessels is associated with vascular occlusive diseases. Vasorelaxant agents may have a role in control of diabetic cardiovascular complications. Gamma aminobutyric acid (GABA) has demonstrated to cause vasorelaxation. The present study was designed to determine i) the vasorelaxatory effect of GABA on diabetic vessels and ii) the role of e...

BACKGROUND Extracellular nucleotides play an important role in the regulation of vascular tone and may be involved in cerebral vasospasm after subarachnoidal haemorrhage. This study was designed to characterise the contractile P2 receptors in endothelium-denuded human cerebral and omental arteries. The isometric tension of isolated vessel segments was recorded in vitro. P2 receptor mRNA express...
