Plasma osmolarity and osmolality measure the concentration of dissolved particles in a fluid, affecting water passage in and out of cell membranes. Changes in osmolarity can indicate dehydration, illness, or other medical problems. Antidiuretic hormone regulates water reabsorption, and significant changes in osmolarity can interfere with cell function. An increase in plasma osmolarity can cause […]
Plasma electrolytic oxidation (PEO) coats metal objects with a ceramic oxide layer, providing resistance to corrosion and wear. PEO uses higher electrical potentials than anodizing, creating plasma discharges that form thick oxide layers. The process dates back to the 1950s and involves inducing metals to form a protective oxide coating under the correct conditions. PEO […]
A plasma engraver uses plasma to create circuit paths on a silicon wafer by depositing or removing silicon dioxide. The plasma is created by superheating a gas containing oxygen or fluorine, and the process is controlled to create precise conductive paths for integrated circuits. A plasma engraver is a device that uses plasma to create […]
To donate plasma, individuals must meet certain criteria and follow specific rules. Donors must be in good health, have no history of high-risk behaviors, and meet age and weight requirements. Testing involves a physical exam, blood pressure check, and sometimes a blood test. Donors with low blood pressure may be ineligible, and those with high […]
Blood plasma centers collect plasma donations for medical treatment of blood disorders. Unlike blood donation, plasma donation is often a for-profit enterprise. Donors must meet certain requirements and are paid a small stipend. It’s important to ensure the center is licensed and adhere to donation frequency requirements. A blood plasma center is a type of […]
Plasma cell dyscrasia is a rare cancer of plasma cells, often caused by exposure to radiation or chemicals. Symptoms include anemia, fatigue, and bleeding. Treatment involves chemotherapy and possibly a bone marrow transplant, but the cancer may recur. Patients should discuss treatment options with multiple oncologists. Plasma cell dyscrasia is a cancer of the plasma […]
