The ICD-11 Beta Draft discusses the syndrome under “LD50.P1 CATCH 22 phenotype". [61] However, since this syndrome is caused by the deletion of a small piece of chromosome 22, some recommend that the name "22q11.2 deletion syndrome (22q11.2DS)" be used.
P1PK blood group system. P1PK (formerly: P) is a human blood group system (International Society of Blood Transfusion system 003) based upon the A4GALT gene on chromosome 22. The P antigen (later renamed P1) was first described by Karl Landsteiner and Philip Levine in 1927. [1] The P1PK blood group system consists of three glycosphingolipid ...
Feb 11, 2018 · Median Lethal Dose Definition. The median lethal dose, or LD50, is a term used in toxicology as a measurement of a lethal dose of a substance (e.g., pathogen, medication, toxic substance, etc.). Specifically, the LD50 represents the dose at which a substance is lethal for 50% of tested subjects. This value is then used as an indicator of a ...
Lethal dose. In toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or type of radiation. Because resistance varies from one individual to another, the "lethal dose" represents a dose (usually recorded as dose per kilogram of subject body weight) at which a given percentage of subjects will die.
LD 50/60: the dose which will kill 50% of the exposed population within 60 days. LD 50/60 in this curve is about 450 cGy as measured in free air, without significant medical intervention. With timely, aggressive, appropriate, continuing medical support, the curve will be shifted to the right, and the LD 50/60 can be significantly higher than ...

Water (Also known as: Dihydrogen Oxide, Purified Water) appears as a clear, nontoxic liquid composed of hydrogen and oxygen, essential for life and the most widely used solvent. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. It can be absorbed via ingestion, inhalation ...
