Sentences with phrase «osmotic pressure»

have demonstrated that extreme changes in osmotic pressure and pH can destabilize the viral envelope.

Concentrated syrups have a high osmotic pressure which prevents micro-organisms growing and reproducing.

The new procedure may lead to a cheap and easy way to create cow «drug factories» that reliably produce human proteins — such as albumin, which restores osmotic pressure after major blood loss — in their milk.

This may be because pregnant women require slightly more salt to maintain osmotic pressure (or fluid balance) as their blood volume expands.

Interestingly, it has the same osmotic pressure as that of blood plasma, and has even been safely administered as an intravenous fluid.

Active sieving also has the potential to filter molecules based on movement dynamics, opening up a whole new avenue in the field of membrane science based on the ability to tune osmotic pressure.

(If you're a science geek, you probably know that sugar creates osmotic pressure, and if you're not, you probably don't care.)

Specifically, he studied how crayfish in Lake Tahoe reacted to various osmotic pressures — that is, the difference between salt concentrations in two bodies of water.

Carbs increase cellular osmotic pressure (cellular hydration) and therefore cell volume.

He generated osmotic pressure curves, and his competency included being able to present them and field questions to his peers.

Studies have demonstrated that extreme changes in osmotic pressure and pH can destabilize the viral envelope.

Robl and Stice, in collaboration with the biotech company Genzyme of Cambridge, Massachusetts, have already created embryos that contain the human gene for albumin protein, which helps restore the blood's osmotic pressure after blood loss.

Point - of - care lab capabilities, including blood gas analysis, chemistries, prothrombin time, activated partial thromboplastin time, colloid osmotic pressure, troponin, ketone and lactate levels.

Caffeine and alcohol dehydrate the body, sugar raises the osmotic pressure inside your veins.

To understand what causes edema, you have to know about two terms: hydrostatic and osmotic pressure.

Consuming too much salt can increase the osmotic pressure inside the veins.

Similar effects will follow if the osmotic pressure falls in the veins or rises in the cells.

Osmotic pressure is generated by proteins and the blood plasma.

The compression technology helps balance the osmotic pressure, which in turn removes the excess fluids.

A layer of live «parenchyma» cells that surrounds the xylem helps tropical trees by storing water and mediating the osmotic pressure so that water can be redistributed to where it is most needed.

The «osmotic pressure» of a filter is critical for molecules to move through the nanopores, but actively changing pores alters the osmotic pressure and changes the status quo.

This suggests that the tuning of the osmotic pressure could be harnessed to further evolve sieving techniques.

FO takes advantage of the osmotic pressure difference between a concentrated «draw» solution and a raw water stream to drive water through a semipermeable membrane.

They showed that the cascade of events culminating in the condensation of the reflectins causes the osmotic pressure inside the lamellae to change drastically due to the expulsion of water, which shrinks and dehydrates the lamellae and reduces their thickness and spacing.

To counter the osmotic pressure that arises between the solutions and force water back through the membrane, desalinization plants must utilize high pressures of 7,000 to 8,300 kilopascals (71 to 86.5 kilogram - force per square centimeter or 1,000 to 1,200 pounds per square inch), he notes.

On June 27th, he spoke to students [at the Lindau Nobel Laureate Meeting] about what he learned from his thesis research, which involved developing a new method to measure the osmotic pressures of mixes of proteins:

«Here's my osmotic pressure measurement.

Biophysics also grew out of investigations on diffusion gradients and osmotic pressure — two forces responsible for the passive flow of matter in living organisms.

Osmotic pressure, the pressure that develops in a solution separated from a solvent by a membrane permeable only to solvent, was first described by Abbé J.A. Nollet, who became professor of experimental physics at the College of Navarre.

In higher plants, most of a cell's volume is taken up by a central vacuole, which primarily maintains its osmotic pressure.

It might be a sign of the «peripheral sink» mechanism, through which the capture of AS in the circulation creates a kind of «osmotic pressure» that draws the more concentrated AS on the other side of the «membrane» of the blood - brain barrier (Figure 3, middle).

High sodium diets are commonly used to study diet induced hypertension, since increasing levels of circulating sodium cause cells to release water (due to osmotic pressure) which elevates the pressure on blood vessel walls.

An effective concentration is not likely to be the same in the body, particulary due to conditions such as osmotic pressure and dilution factors.

Sodium helps regulate water balance and osmotic pressure.

Circulating calcium also plays a part in keeping your pet's body fluids in their proper place (by contributing to osmotic pressure).
