World Blood Donor Day falls on the birthday of Karl Landsteiner
(June 14, 1868).
The Day June 14th is the birthday of Karl Landsteiner
(1863-1943), who was a biologist and physician and was the founder of modern blood transfusion.
In the early 1900s, Karl Landsteiner
was the first to demonstrate the phenotypic differences of the blood group system, later known as the ABO blood group system.
is well known for the discovery of ABO blood group in 1901 AD.
At the turn of the 20th century, Karl Landsteiner
first described the existence of serological differences between individuals and stated that people of the world, irrespective of their race can be divided into four groups depending on the substances present on the surface of their red blood cells.
A research project recently initiated at Karl Landsteiner
University of Health Sciences aims to produce organ models with realistic material properties.
Transfusion, by now with human blood, only thrived after Karl Landsteiner
understood in 1901 that there were blood groups, and that mixing them could be fatal.
Nobel medicine laureates have included scientific greats such as Alexander Fleming, the discoverer of penicillin, and Karl Landsteiner
, whose identification of separate blood types opened the way to carrying out safe transfusions.
Its prevalence is increasing in adolescents because of sedentary and unhealthy lifestyle and increasing trends towards obesity in children and teenagers.2 Previous researches have shown that high blood pressure is associated with many genetic markers and familial patterns.1 There are empirical evidences suggesting its linkage with blood groups.1 The International Society of Blood Transfusion has identified thirty-three various blood group systems.3 Clinically, the most important system is ABO system4 which was discovered by Karl Landsteiner
The "(https://www.ncbi.nlm.nih.gov/pubmed/20406014) MNS blood group antigens " were discovered in the 1920s by Karl Landsteiner
(the same scientist who discovered the ABO system).
An important part of the history of blood banking occurred in 1901, when an Austrian physician by the name of Karl Landsteiner
, made reference of the first three human blood groups namely A, B and O.
De todos los sistemas el grupo sanguineo ABO, descubierto hace mas de 100 anos en 1900 por Karl Landsteiner
constituidos por antigenos del tipo carbohidratos, y el factor Rh con antigenos del tipo proteico descubierto en 1939, han sido los mas estudiados debido a su importancia en medicina transfusional, en ginecologia y neonatologia, y en trasplantes de organos solidos, ademas del hecho de que estos poseen un patron de herencia genetico, ha permitido su uso como marcadores geneticos en estudios familiares y sobretodo poblacionales estableciendo fenomenos de mestizaje al determinar la distribucion de los mismos en diferentes poblaciones (2,3).
