Cryoprecipitate, also called cryo for short, or Cryoprecipitate Antihemophilic factor (AHF), is a frozen blood product prepared from blood plasma. [1] To create cryoprecipitate, Plasma is slowly thawed to 1–6 °C. A cold-insoluble precipitate is formed, which is collected by centrifugation, resuspended in a small amount of residual plasma ...
Fresh frozen plasma is made up of a complex mixture of water, proteins, carbohydrates, fats, and vitamins. [1] When frozen it lasts about a year. [1] Plasma first came into medical use during the Second World War. [1] It is on the World Health Organization's List of Essential Medicines. [7] In the United Kingdom it costs about £30 per unit. [8]
By implementing rapid sorption-desorption kinetics and operating 14–24 cycles per day, this technique produced an equivalent water yield of 5.8–13.3 L kg −1 of sustainable raw materials, demonstrating the potential for low-cost, scalable atmospheric water harvesting.
The term cryosupernatant (also called cryo-poor plasma, cryoprecipitate depleted, cryoprecipitate reduced plasma) refers to plasma from which the cryoprecipitate has been removed. It is used to treat thrombocytopenic purpura .
Vapor surrounds the planet but is unevenly distributed. The image loop on the right shows monthly average of water vapor content with the units are given in centimeters, which is the precipitable water or equivalent amount of water that could be produced if all the water vapor in the column were to condense. The lowest amounts of water vapor (0 ...
Vapor pressure is measured in the standard units of pressure. The International System of Units (SI) recognizes pressure as a derived unit with the dimension of force per area and designates the pascal (Pa) as its standard unit. [1] One pascal is one newton per square meter (N·m −2 or kg·m −1 ·s −2).
Tubes of biological samples being placed in liquid nitrogen. One early theoretician of cryopreservation was James Lovelock.In 1953, he suggested that damage to red blood cells during freezing was due to osmotic stress, [9] and that increasing the salt concentration in a dehydrating cell might damage it.
Also called heat content per unit mass. In the approximation of ideal gases, lines of constant enthalpy are parallel to lines of constant WBT. Enthalpy is given in (SI) joules per kilogram of air, or BTU per pound of dry air. Specific volume is the volume of the mixture (dry air plus the water vapor) containing one unit of mass of "dry air".
