Valproate has a broad spectrum of anticonvulsant activity, although it is primarily used as a first-line treatment for tonic–clonic seizures, absence seizures and myoclonic seizures and as a second-line treatment for partial seizures and infantile spasms.
A calcium channel is an ion channel which shows selective permeability to calcium ions. It is sometimes synonymous with voltage-gated calcium channel, [1] which are a type of calcium channel regulated by changes in membrane potential. Some calcium channels are regulated by the binding of a ligand.
An L-type calcium channel with its subunits labeled along with some drugs known to inhibit the channel. The L-type calcium channel (also known as the dihydropyridine channel, or DHP channel) is part of the high-voltage activated family of voltage-dependent calcium channel. [2] "L" stands for long-lasting referring to the length of activation.
Valproic acid, and its derivatives such as sodium valproate and divalproex sodium, causes cognitive deficit in the child, with an increased dose causing decreased intelligence quotient and use is associated with adverse neurodevelopmental outcomes (cognitive and behavioral) in children.
This gene encodes Ca v 3.2, a T-type member of the α 1 subunit family, a protein in the voltage-dependent calcium channel complex. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization and consist of a complex of α 1, α 2 δ, β, and γ subunits in a 1:1:1:1 ratio.
When calcium ions (Ca 2+) are depleted from the endoplasmic reticulum (a major store of Ca 2+) of mammalian cells, the CRAC channel is activated to slowly replenish the level of calcium in the endoplasmic reticulum. The Ca 2+ Release-activated Ca 2+ (CRAC) Channel (CRAC-C) Family (TC# 1.A.52) is a member of the Cation Diffusion Facilitator (CDF ...
Calcium SOCs are especially important for the cell because they are the major source of intracellular calcium; and calcium itself is involved in a wide array of vital cellular functions. SOCs are so called because they are activated by intracellular calcium (particularly the endoplasmic reticulum (ER)) stores depletion by both physiological or ...
For example, a typical ER fluid can go from the consistency of a liquid to that of a gel, and back, with response times on the order of milliseconds. [1] The effect is sometimes called the Winslow effect after its discoverer, the American inventor Willis Winslow, who obtained a US patent on the effect in 1947 [ 2 ] and wrote an article ...
