Porosimetry is an analytical technique used to determine various quantifiable aspects of a material's porous structure, such as pore diameter, total pore volume, surface area, and bulk and absolute densities. The technique involves the intrusion of a non-wetting liquid (often mercury) at high pressure into a material through the use of a ...

Hemoglobin Lepore syndrome is typically an asymptomatic hemoglobinopathy, which is caused by an autosomal recessive genetic mutation.The Hb Lepore variant, consisting of two normal alpha globin chains (HBA) and two delta-beta globin fusion chains which occurs due to a "crossover" between the delta (HBD) and beta globin (HBB) gene loci during meiosis and was first identified in the Lepore ...
Sickle cell disease is a group of inherited blood disorders, caused by a genetic abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [57] Under certain circumstances, this leads to the red blood cells adopting an abnormal sickle -like shape; with this shape, they are unable to deform as they pass through capillaries ...
Whereas normal adults have less than 1% of hemoglobin F, patients with only one disease gene have 5-30%. Patients with two disease copies can have hemoglobin F in up to 100% of red blood cells. [31] As other diseases such as sickle cell disease could also cause a higher level of hemoglobin F to be present, it can sometimes be misdiagnosed. [32]
Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are generally single-gene disorders and, in most cases, they are inherited as autosomal recessive traits. [2] [3]
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
