One such pathway, the hypoxic response pathway, is activated by reduced local oxygen concentrations at the tumor site. Hypoxia-driven gene and protein changes enhance epithelial-to-mesenchymal ...

Serotonin can promote both pulmonary vasoconstriction and pulmonary vascular remodeling and is thought to be involved in the pathobiology of PAH. A polymorphism in the serotonin transporter (SERT ...

However, the term "hypoxia," if it means a deficiency of oxygen supply to the body, is quite a different thing from hypoxemia. The term hypoxia should probably not be used so commonly or so glibly.

Maximal vasodilation can increase cutaneous blood flow to 3000 ml/minute (average flow is 300-500 ml/minute). 2. Vasoconstriction - decreases blood flow to periphery, decreases heat loss. Maximal ...
