If you have glaucoma, don’t use eye drops with vasoconstrictors --decongestantsthat makebloodvessels in your eye smaller. That will boost your eye pressure. Herpes simplexeye infection:Early symptoms of this virus may include a painful sore on your eye surface or eyelid, and an inflamed cor...
The heart, blood vessels, and kidney are all effectors of arterial blood pressure. The equilibrium or stability of the internal environment of organisms in a changing external environment, maintained by many physiological adjustment mechanisms. A group of chemicals (co-transmitters) that facilitate ...
As a comparison, this is lower than physiological blood pressure which in humans is 10–20 kilopascals. Abrupt or large changes in the solute concentration can lead to changes in cortical stress and hydrostatic pressure gradients, resulting in water flux across the cell. In the next section, we...
At other times it pours out very fast as huge amounts of pressure force it from the volcano. During these times, it moves almost as quickly as water moving down the side of a mountain.When the lava from Kilauea reaches the ocean, its fierce heat produces great amounts of steam that ...
Dengue viruses are the most important arboviral pathogens in the world, which have adapted to human transmission and replication over several hundred years and were initially recognized to cause outbreaks of clinical disease in tropical and subtropical c
Adrift on the dark ocean of delirium, he had held on to this alluring force, a distant drumming in time with his pulse, an atavistic summons from the heart of the jungle. When his illness was driven out, his wide-eyed, distant stare remained. Some mornings, we would find him awake ...
uteroplacental blood flowLow levels of maternal estrogens are commonly regarded as indicators of fetal stress. We continuously monitored distal aortic blood flow by flowmeter, fetal heart rate, and amniotic fluid pressure in seven pregnant baboons near term. Four of the animals received a constant ...

Some common symptoms of this poisoning include low blood pressure (hypotension), vomiting, nausea, and death resulting from hypotensive shock (Lee, 2008). In southern Chile, Gracilaria species are used as manure in the form of powder, liquid, or whole decomposing plants to cultivate potatoes (...
