What vitamin D does or doesn’t do for a body that is salt/SCNâ» deficient
Vitamin D isnât just a bone booster, itâs a metabolic amplifier, and its effects shift dramatically depending on the integrity of the terrain. In a body deficient in salt (sodium) and thiocyanate (SCNâ»), vitamin Dâs usual benefits may be blunted, misdirected, or even destabilizing. đ What Vitamin D Does in a Coherent Terrain In a…

Asynchronous Muscles
Asynchronous muscles are muscles in which there is no one-to-one relationship between electrical stimulation and mechanical contraction. These muscles are found in 75% of flying insects and have convergently evolved 7-10 times.[1] Unlike their synchronous counterparts that contract once per neural signal, mechanical oscillations trigger force production in asynchronous muscles. Typically, the rate of mechanical contraction is an order of magnitude…

Weddellite and Whewellite
Weddellite (CaC2O4·2H2O) is a mineral form of calcium oxalate named for occurrences of millimeter-sized crystals found in bottom sediments of the Weddell Sea, off Antarctica. Occasionally, weddellite partially dehydrates to whewellite, forming excellent pseudomorphs of grainy whewellite after weddellite’s short tetragonal dipyramids. It was first described in 1936 but only named in 1942. Structural properties Weddellite, or calcium oxalate dihydrate, crystallises in a tetragonal system: the classic crystal…

Agrin is a large chimeric proteoglycan, a heparan sulfate and chondroitin proteoglycan, whose best-characterised role is in the development of the neuromuscular junction during embryogenesis
Agrin was originally found in the electric organ of Tarpedo california and in the basal lamina at the neuromuscular junction as a protein that directs the aggregation of acetylcholine receptors (AChR) and acetylcholinesterase (AChE) at synaptic sites. Tetronarce californica also known as the Pacific electric ray is a species of electric ray in the family Torpedinidae, endemic to the coastal waters of the northeastern Pacific Ocean from Baja California to British Columbia. It generally inhabits sandy flats, rocky reefs, and kelp forests from the surface…

The chief cells of the parathyroid glands sense the amount of calcium in the blood, and release the calcium-increasing hormone parathyroid hormone (PTH) accordingly
Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are one of the two cell types of the parathyroid glands, along with oxyphil cells. The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells. It is perceived that oxyphil cells may be derived from chief cells at puberty, as they are not present at…

The hyperventilation syndrome: a neurosis or a manifestation of magnesium imbalance? (1985)
It has been proven with clinical, psychological and electromyographic tests that the hyperventilation (HV) syndrome cannot be separated from so-called genuine tetany. Tetanic patients with and without HV are characterized by a significant hypocalcemia; but a significant hypomagnesemia is exclusively found in tetanic patients with HV attacks. Possible pathogenic mechanisms are discussed which may explain…

Latent tetany and anxiety, marginal magnesium deficit, and normocalcemia (1975)
The identification of marginal magnesium deficit, such as we have detected in a patient with anxiety, depression, and psychomatic complaints, is a difficult diagnostic problem. Electromyography of a limb, rendered acutely ischemic either just before or after hyperventilation, can elicit latent tetany in this condition, as well as in calcium deficiency. We have demonstrated iterative…

Moulting was known as mewing in medieval times
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle. In medieval times it was also…

Ryania speciosa, Ryanodine and Ryanoids
Ryania speciosa is a species of plant in the family Salicaceae. The species is significant partly because the ryanoid insecticides are derived from, and have the same mode of action as the alkaloid ryanodine, which was originally extracted from this South American plant, which is also used as a piscicide (fish poison). M. Vahl, 1797 In: Eclog. Am. 1: 51, t. 9 (1796) [1797] The Plant list Roskov…

Cadherin-1
Cadherin-1 or Epithelial cadherin(E-cadherin), (not to be confused with the APC/C activator protein CDH1) is a protein that in humans is encoded by the CDH1gene.[5] Mutations are correlated with gastric, breast, colorectal, thyroid, and ovarian cancers. CDH1 has also been designated as CD324 (cluster of differentiation 324). It is a tumor suppressor gene.[6][7] History The discovery of cadherin cell-cell adhesion proteins is attributed to Masatoshi Takeichi, whose experience…

Anti-lymphocyte globulin (ALG)
Anti-lymphocyte globulin (ALG) is an infusion of animal- antibodies against human T cells which is used in the treatment of acute rejection in organ transplantation. Its use was first reported by Thomas Starzl in 1966.[1] Its use in transplant was supplanted by thymoglobulin between 1984 and 1999.[2] It has also been used in the treatment of aplastic anemia.[3][4][5] It is less commonly used than the similar anti-thymocyte globulin (ATG), and like ATG it is…

Calcitonin
Calcitonin is a 32 amino acid peptide hormone secreted by PARAFOLLICULAR CELLS (also known as C cells) of the thyroid (or endostyle) in humans and other chordates in the ultimopharyngeal body. It acts to reduce blood calcium (Ca2+), opposing the effects of PARATHYROID HORMONE (PTH). Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the…
