Iodopyridones

D007469 |
[Iodinated pyridine derivatives that are often used as contrast media.

|
Iodoquinol
|
D004103 |
[One of the halogenated 8-quinolinols widely used as an intestinal antiseptic, especially as an antiamebic agent. It is also used topically in other infections and may cause CNS and eye damage. It is known by very many similar trade names world-wide.

|
Iofetamine
|
D020367 |
[An amphetamine analog that is rapidly taken up by the lungs and from there redistributed primarily to the brain and liver. It is used in brain radionuclide scanning with I-123.

|
Ioglycamic Acid
|
D007471 |
[A radiopaque medium. It is a mixture of its meglumine and sodium salts and is used to visualize the biliary tract.

|
Iohexol
|
D007472 |
[An effective non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality.

|
Ion Channel Gating
|
D015640 |
[The opening and closing of ion channels due to a stimulus. The stimulus can be a change in membrane potential (voltage-gated), drugs or chemical transmitters (ligand-gated), or a mechanical deformation. Gating is thought to involve conformational changes of the ion channel which alters selective permeability.

|
Ion Channels
|
D007473 |
[Gated, ion-selective glycoproteins that traverse membranes. The stimulus for ION CHANNEL GATING can be due to a variety of stimuli such as LIGANDS, a TRANSMEMBRANE POTENTIAL DIFFERENCE, mechanical deformation or through INTRACELLULAR SIGNALING PEPTIDES AND PROTEINS.

|
Ion Exchange
|
D007474 |
[Reversible chemical reaction between a solid, often one of the ION EXCHANGE RESINS, and a fluid whereby ions may be exchanged from one substance to another. This technique is used in water purification, in research, and in industry.

|
Ion Exchange Resins
|
D007475 |
[High molecular weight, insoluble polymers which contain functional groups that are capable of undergoing exchange reactions (ION EXCHANGE) with either cations or anions.

|
Ion Mobility Spectrometry
|
D000075663 |
[Techniques for separation and identification of ionized molecules based on their drift through a gas phase after being accelerated by an electric field. Their mobilities will be effected by their shape, size, and charge.

|
Ion Pumps
|
D016623 |
[A general class of integral membrane proteins that transport ions across a membrane against an electrochemical gradient.
] |
|
Ion Transport
|
D017136 |
[Ion transport that derives its energy from the concentration gradient of the ion itself.
, The movement of ions across energy-transducing cell membranes. Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.
, Transport of ions down a concentration gradient at greater rates than would occur through passive diffusion through a pore.
, Ion transport that is coupled to an energy-yielding process. When proteins such as ION PUMPS couple transport directly to a chemical or photochemical reaction such as ATP hydrolysis the process is considered primary active transport pumps. Secondary active transport utilizes the voltage and ion gradients produced by the primary transport to drive the cotransport of other ions or molecules. SYMPORTERS may use secondary active transporters to transport ions in the same direction (symport). ANTIPORTERS may use secondary active transporters to transport ions in the opposite direction (antiport).

Ion-Selective Electrodes
|
D017736 |
[Electrodes which can be used to measure the concentration of particular ions in cells, tissues, or solutions.
] |
|
Ionic Liquids
|
D052578 |
[Salts that melt below 100 C. Their low VOLATILIZATION can be an advantage over volatile organic solvents.
] |
|
Ionomycin
|
D015759 |
[A divalent calcium ionophore that is widely used as a tool to investigate the role of intracellular calcium in cellular processes.
] |
|
Ionophores
|
D007476 |
[Chemical agents that increase the permeability of biological or artificial lipid membranes to specific ions. Most ionophores are relatively small organic molecules that act as mobile carriers within membranes or coalesce to form ion permeable channels across membranes. Many are antibiotics, and many act as uncoupling agents by short-circuiting the proton gradient across mitochondrial membranes.

|
Ions
|
D007477 |
[An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.
] |
|
Iontophoresis
|
D007478 |
[Therapeutic introduction of ions of soluble salts into tissues by means of electric current. In medical literature it is commonly used to indicate the process of increasing the penetration of drugs into surface tissues by the application of electric current. It has nothing to do with ION EXCHANGE; AIR IONIZATION nor PHONOPHORESIS, none of which requires current.

Iopamidol
|
D007479 |
[A non-ionic, water-soluble contrast agent which is used in myelography, arthrography, nephroangiography, arteriography, and other radiological procedures.
