Demineralization (physiology)
Demineralization - it is the opposite process of mineralization, a process to reduce the content of mineral substances in tissue or organism, such as bone demineralization, of teeth. Demineralization can lead to serious diseases such as osteoporosis or tooth decay. Usually, treatment involves administration of appropriate dietary supplements to help restore the remineralization In biogeochemistry, remineralisation (or remineralization) refers to the breakdown or transformation of organic matter (those molecules derived from a biological source) into its simplest inorganic forms. These transformations form a crucial link ... of human tissues and their physiological state. References {{Reflist Physiology ...

Bone Mineralization
Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, often to harden or stiffen existing tissues. Such tissues are called mineralized tissues. It is an extremely widespread phenomenon; all six taxonomic kingdoms contain members that are able to form minerals, and over 60 different minerals have been identified in organisms. Examples include silicates in algae and diatoms, carbonates in invertebrates, and calcium phosphates and carbonates in vertebrates. These minerals often form structural features such as sea shells and the bone in mammals and birds. Organisms have been producing mineralized skeletons for the past 550 million years. Calcium carbonates and calcium phosphates are usually crystalline, but silica organisms (sponges, diatoms...) are always non crystalline minerals. Other examples include copper, iron and gold deposits involving bacteria. Biologically formed minerals often have special uses such as magnetic ...

Remineralisation Of Teeth
Tooth remineralization is the natural repair process for non-cavitated tooth decay, tooth lesions, in which calcium, phosphate and sometimes fluoride ions are deposition (chemistry), deposited into crystal voids in demineralised Tooth_enamel, enamel. Remineralization can contribute towards restoring strength and function within tooth structure. Demineralization is the removal of minerals (mainly calcium) from any of the hard tissues: Tooth enamel, enamel, dentine, and cementum.Li X, Wang J, Joiner A, Chang J. The remineralization of enamel: a review of the literature. Journal of dentistry. 2014 Jun 30;42:S12-20. It begins at the surface, and may progress into either cavitation (tooth decay) or erosion (tooth wear). Tooth decay demineralization is caused by acids from bacteria in the dental plaque biofilm whilst tooth wear is caused by acids from non-bacterial sources. These can be extrinsic in source, such as carbonated drinks, or intrinsic acids, usually from stomach acid coming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demineralizing (silk Worm Cocoon)
Demineralizing has the potential to be used in the silk sector enabling wet reeling of Wild Silk moth cocoons by removing the mineral layer present in these cocoons. This technique is not like degumming where the gum of the fibroin fibres is removed what would lead to a tangled cocoon. With "demineralizing" the gum and structure of the cocoon is kept intact enabling the cocoons to be wet reeled. This could allow a new silk industry in areas which have not the conditions or infrastructure for raising the domesticated silk worm '' Bombyx mori'', possibly generating a revolutionary new income stream. Standard demineralizing solution An aqueous 1 M solution of ethylenediaminetetraacetic acid (EDTA) is used adjusted to pH 10 with saturated sodium hydroxide solution. The cocoons are immersed in this solution for 72 h at 40 °C and gently stirred. During the process, the cocoons are kept under the surface of the solution by means of a plastic mesh, using a partial vacuum to encourage p ...

Deionization
Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Distilled water was, formerly, the most common form of purified water, but, in recent years, water is more frequently purified by other processes including capacitive deionization, reverse osmosis, carbon filtering, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodeionization. Combinations of a number of these processes have come into use to produce ultrapure water of such high purity that its trace contaminants are measured in parts per billion (ppb) or parts per trillion (ppt). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities. It is also used in the commercial beverage industry as the primary ingredient of any given trademarked bottling formula, in order to maintain product consistency. It can be produced on-site for imme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desalination
Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in Soil salinity control, soil desalination, which is an issue for agriculture. Saline water, Saltwater (especially Seawater, sea water) is desalinated to produce water suitable for Drinking water, human consumption or irrigation. The by-product of the desalination process is brine. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water resources. Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, Reclaimed water, water recycling and water conservation. However, these alternatives are not always available and depletion of reserve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
