The signs of REM sleep (muscle paralysis, EEG desynchrony, eye movements) occur in mammals. Did sleep evolve to keep our ancestors away from predators? Indus Dolphins sleep even though it's dangerous. These dolphins exist in muddy water and through natural selection have become blind because it served no purpose. Why then do they still sleep?
Sweat chloride measurements are used in the laboratory diagnosis of cystic fibrosis. Chloride Titration. The ChloroChek Chloridometer is a coulometric titrator designed to determine chloride ion concentrations in sweat samples with just 10 microliters of sweat. It displays the concentration directly in mmol/L Cl-. The sweat sample is added to an acid buffer/stabilizer working solution.
Guide. A sweat test measures the amount of salt chemicals (sodium and chloride) in sweat. It is done to help diagnose cystic fibrosis. Normally, sweat on the skin surface contains very little sodium and chloride.People with cystic fibrosis have 2 to 5 times the normal amount of sodium and chloride in their sweat.During the sweat test, medicine that causes a person to sweat is applied to the skin (usually on the arm or thigh).The sweat is then collected on a paper or a gauze pad, and the amount of salt chemicals in the paper or gauze is measured in a lab. Generally, chloride (sweat chloride) is measured.eople with cystic fibrosis have 2 to 5 times the normal amount of sodium and chloride in their sweat. During the sweat test, medicine that causes a person to sweat is applied to the skin (usually on the arm or thigh).
