Iodine deficiency iodate as dough conditioner in bread and baked goods was gradually replaced by the use of other conditioning agents such as bromide. Iodine deficiency resulting in goiter occurs in 187 million people globally (2.7% of the population). It resulted in 2700 deaths in 2013 up from 2100 deaths in 1990. A low amount of thyroxine (one of the two thyroid hormones) in the blood, due to lack of dietary iodine to make it, gives rise to high levels of thyroid stimulating hormone (TSH), which stimulates the thyroid gland to increase many biochemical processes; the cellular growth and proliferation can result
Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde Merthiolate-Iodine-Formaldehyde (MIF) is a solution used in biomedical laboratories for concentration of stool samples prior to microscopic investigation for parasites. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non-concentrated samples the likelihood of finding equivalents of actually present parasites is too low. MIF enables separation of different strata of stool matter, and sedimentation of stool particles that contain parasites (usually parasite eggs). After application of MIF, usually centrifugation is used for acceleration of sedimentation. The term "Merthiolate" indicates presence of thiomersal in the solution. Due to the hazardous qualities of thiomersal, it is
