The human immune system recognizes these molecules and, upon encountering a molecule different from the type regularly present in the body, treats it as a foreign element that should be attacked. For example, if a person with type O blood receives a type A blood donation, his body will recog...
Macrocyticanemiais a kind of anemia in which the erythrocytes (red blood cells) are abnormally big, a condition called macrocytosis or macrocythemia. The size of these red blood cells (RBCs) makes them more likely to rupture prematurely. However, like with all types of anemia, macrocytic anem...
Glucose is a form of monosaccharide which is found to be the source of energy in living organisms such as humans. In humans, glucose is found in blood, which is why it's referred to as "blood sugar"Answer and Explanation: The most common form of glucose is d-glucose. It is naturally...
Red blood cells are one of the formed elements of the blood other than platelets and white blood cells. The production of red blood cells from hemocytoblasts in the red bone marrow is regulated by the hormone erythropoietin.Answer and Explanation: The molecule in the red bloo...

DNA is the molecule that contains all of the information required to build and maintain the cell; RNA has several roles associated with expression of the information stored in DNA. Of course, nucleic acids alone aren't responsible for the preservation and expression of genetic material: Cells ...
Therefore, estimation of the accumulated internal dose and the exposure from such electrophilic, short-lived compounds and metabolites is easier through measurement of Hb adducts than of DNA adducts. Compared to white blood cells, required to obatin DNA, red blood cells (RBC) may also be easier...
in the body in the structure of cell membranes. It is also a precursor to the formation of hormones, including estrogen and testosterone, which also are steroids. However, high levels of LDL cholesterol can lead to plaque deposits in blood vessels and potentially to high blood pressure and ...
What Is the Best Way to Isolate Naïve Cells? Isolating pure cell populations from peripheral blood using standard venipuncture methods is often not a scalable source for the demands of cellular research. Leukopaks, an apheresis product, is ahuman peripheral blood mononuclear cells(PBMC) rich mat...
