Synthesis of Ge1−x Sn x Alloy Thin Films Using Ion Implantation and Pulsed Laser Melting (II-PLM)
Ge1−x Sn x thin films are interesting for all-group-IV optoelectronics because of a crossover to a direct bandgap with dilute Sn alloying. However, Sn has vanish...

Survival, neuron-like differentiation and functionality of mesenchymal stem cells in neurotoxic environment: the critical role of erythropoietin
Mesenchymal stem cells (MSCs) can ameliorate symptoms in several neurodegenerative diseases. However, the toxic environment of a degenerating central nervous system (CNS) characterized by hypoxia, glutamate (G...

247 Contractile Endothelin B Receptors on the Smooth Muscle Cells of the Human Umbilical Vein
Background: Endothelin triggers vasoconstriction via activation of endothelin A (ETA) and endothelin B2 (ETB2) receptors on vascular smooth muscle cells and vasodilation by stimulating the release of nitric ox...

Connective Tissue: More Than Just a Matrix for Cells
The general function of connective and supporting tissues consists, as the term implies, in the association of cells, the connection of the different tissues within the organs, the interrelation between the or...

Vascular Smooth Muscle
Smooth Muscle Tissue. The visceral mesenchyma (splanchnopleura) is the principal source for smooth muscle tissue. It also forms the layer-shaped muscle and connective tissue strata of the vessel ...

The Effect of Prostacyclin Analogs on Vascular K Channels
Drugs such as pinacidil, nicorandil, minoxidil sulphate and cromakalim effect vasodilatation by membrane hyperpolarization of the vascular smooth muscle cells, which in some tissues raises the membrane potenti...

Potassium Channel Activation in Vascular Smooth Muscle
K+ channel opening causing membrane hyperpolarization in vascular smooth muscle and thereby vasodilatation, cannot be rated as the ‘newly discovered’ action principle of certain pharmacological substances but ...

NMR Studies of Cation Induced Conformational Changes in Anionic Biopolymers at the Endothelium-Blood Interface
In the vessel walls, the connective tissue components surrounding the smooth muscle cells display a high binding capacity for small cations which has been ascribed to the presence of polyanionic proteoglycans. 23

Autorhythmicity in Blood Vessels: Its Biophysical and Biochemical Bases
The rhythmogenic properties of vascular smooth muscle are closely linked to the intact circulation. The electrical and mechanical oscillations, which can be traced back to rhythmic activity of the active, elec...

Role of EDHF, PGI2, and Norepinephrine in Hypoxic Vasorelaxation and Vasoconstriction
In the following chapter we will discuss an aspect of peripheral chemoreception, that is oxygen sensing by peripheral blood vessels. The reaction of blood vessels to a lowering of the oxygen partial pressure i...

Vascular Smooth Muscle Reactivity in Hypoxia
Arterial as well as tissue hypoxia induces vasodilation and a subsequent increase of blood flow in several organs [2,5,7,11,13]. In brain tissue regional blood flow increases significantly if the arterial oxyg...

Membrane Hyperpolarization in Hypoxic Vasorelaxation
Shortly after the discovery of endothelium-dependent relaxation of smooth muscle cells in blood vessels (1) it became apparent that endothelial cells also could generate vasoconstrictor signals (2). Both endot...

On the Convergence of Types for Radon Probability Measures in Banach Spaces
A Radon probability measure v on a Banach space F belongs to the same type as a measure μ on a Banach space E provided that v = T(μ) * δ y for some linear operator T ...

The Interaction Between Oxygen and Vascular Wall
During the last decade the important role of endothelium in the local control of vascular smooth muscle function has become more and more evident. In response to various chemical and physical stimuli, vascular...

PO2-Induced Changes of Membrane Potential and Tension in Vascular Smooth Musculature
That a decrease in oxygen tension leads to vasodilatation has been known from the literature for a long time. Mechanical measurements demonstrate that hypoxia effects relaxation of vascular strips [8, 9,10, 33...

The Influence of Oxygen Tension on Membrane Potential and Tone of Canine Carotid Artery Smooth Muscle
During arterial hypoxia the brain blood flow rate increases when oxygen tensions below approximately 60 mmHg are attained (Betz, 1972; Grote and Schubert, 1982; Kuschinsky, and Wahl, 1978). Tissue PO2 measurement...
