DO HUMAN BEINGS HAVE THE AGE OF THEIR BLOOD VESSELS?
- Formation of endothelial cell networks. Helminger, Gabriel; Endo, Mitsuhiro; Ferrara, Napoleone; Hlatky, Lynn; Jain, Raskesh K. // Nature;5/11/2000, Vol. 405 Issue 6783, p139
Focuses on a study that shows that vascular endothelial growth factor (VEGF) can stimulate the elongation, network formation and branching of non-proliferating endothelial cells in culture that are deprived of oxygen and nutrients. Details of the study; Vascular sprouting and remodelling.
- Development of a Wearable System Module for Monitoring Physical and Mental Workload. Sinbae Kim; Hiromi Nakamura; Toshihiko Yoshida; Masamichi Kishimoto; Yohsuke Imai; Noriaki Matsuki; Takuji Ishikawa; Takami Yamaguchi // Telemedicine & e-Health;Nov2008, Vol. 14 Issue 9, p939
A wearable computer with a simple electrocardiogram monitoring device and an accelerometer to measure femoral artery pulse was developed and deployed in the homes of 8 healthy individuals. These individuals participated in a variety of physical and mental tasks, and measurements were taken with...
- Brachial Artery Differential Characteristic Impedance: Contributions from Changes in Youngâ€™s Modulus and Diameter. John Li // Cardiovascular Engineering: An International Journal;Mar2009, Vol. 9 Issue 1, p11
AbstractÂ Â This examination of brachial artery (BA) differential characteristic impedance, Î”Z c, illustrates that changes in Z c can occur from changes in either BA wall stiffness (Youngâ€™s modulus, E) and/or its diameter, D. Furthermore, we assessed how changes in both E and D...
- Endothelium. // Encyclopedic Reference of Cancer;2001, p292
A definition of the term "endothelium" is presented, referring to a single sheet of highly flattened cells that forms the lining of all blood vessels.
- Article amendments. // Journal of Clinical Investigation;Jul2009, Vol. 119 Issue 7, p2113
Corrections to articles that were published in the previous issues including "Curcumin prevents and reverses murine cardiac hypertrophy," "Currying favor for the heart" and "The FGF system has a key role in regulating vascular integrity" are presented.
- Endothelial progenitor cells, endothelial cell dysfunction and much more: observations from cardiac syndrome X. Goon, Patrick K. Y.; Lip, Gregory Y. H. // Heart;Sep2007, Vol. 93 Issue 9, p1020
The author reflects on the medical observation from cardiac syndrome X (CSX), particularly on endothelial progenitor cells (EPCs) and endothelial cell dysfunction. He mentions that the presentation of EPCs as an experimental tool in vascular research helps in understanding the various health...
- Blood Flow Measurement in Patients With Intermittent Claudication. Davies, W. Tudor // Angiology;Mar1980, Vol. 31 Issue 3, p164
Modified isotope clearance tests for the objective investigation of intermittent claudication of the lower limb were performed in 14 normal subjects with clinically patent arteries and 9 patients with calf claudication and arteriographically confirmed peripheral vascular occlusion. The tests...
- Endothelial Progenitor Cells May Reduce Cardiovascular Disease. Ninger, Laura J. // Life Extension;Apr2009, Vol. 15 Issue 4, p23
The article reports on the significant part of endothelial progenitor cells (EPCs) in normal blood vessel function. It notes that EPCs, which circulate in the blood stream, may be reduced and a potential treatment to cardiovascular disease. Moreover, EPCs are cited to help create and repair...
- The association of arterial shear and flow-mediated dilation in diabetes. Gibbs, Bethany Barone; Dobrosielski, Devon A.; Lima, Michael; Bonekamp, Susanne; Stewart, Kerry J.; Clark, Jeanne M. // Vascular Medicine;Aug2011, Vol. 16 Issue 4, p267
While adjusting flow-mediated dilation (FMD), a measure of vascular function, for shear rate may be important when evaluating endothelial-dependent vasodilation, the relationship of FMD with shear rate in study populations with cardiovascular risk factors is unclear. We aimed to investigate the...
