Lyodura was introduced in 1969 as a product of B. Braun Melsungen AG , a leading hospital supply co... | https://en.wikipedia.org/wiki/Lyodura |
Lyoluminescence refers to the emission of light while dissolving a solid into a liquid solvent . It is a form of chemiluminescence . The most common lyoluminescent effect is seen when solid samples which have been heavily irradiated by ionizing radiation are dissolved in water. The total amount of light emitted by the... | https://en.wikipedia.org/wiki/Lyoluminescence |
Lyotropic liquid crystals result when amphiphiles , which are both hydrophobic and hydrophilic , dissolve into a solution that behaves both like a liquid and a solid crystal . This liquid crystalline mesophase includes everyday mixtures like soap and water. [ 1 ] [ 2 ]
The term lyotropic comes from Ancient Greek λύω (... | https://en.wikipedia.org/wiki/Lyotropic_liquid_crystal |
Lysergic acid , also known as D -lysergic acid and (+)-lysergic acid , is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and found in the seeds of Argyreia nervosa ( Hawaiian baby woodrose ), and Ipomoea species ( morning glories , ololiuhqui , tlitliltzin ).

A field lysimeter (from Greek λύσις (loosening) and the suffix -meter ) is a cylindrical container filled with soil , which can be used to study the transport of water and material through the soil. This type of lysimeter can be equipped with different measuring probes at different depths (e.g., soil temperature, tensi... | https://en.wikipedia.org/wiki/Lysimeter |
Lysis ( / ˈ l aɪ s ɪ s / LY -sis ; from Greek λῠ́σῐς lýsis 'loosening') is the breaking down of the membrane of a cell , often by viral , enzymic , or osmotic (that is, "lytic" / ˈ l ɪ t ɪ k / LIT -ik ) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate . In mole... | https://en.wikipedia.org/wiki/Lysis |
A lysis buffer is a buffer solution used for the purpose of breaking open cells for use in molecular biology experiments that analyze the labile macromolecules of the cells (e.g. western blot for protein, or for DNA extraction ). Most lysis buffers contain buffering salts (e.g. Tris-HCl ) and ionic salts (e.g. NaCl ) t... | https://en.wikipedia.org/wiki/Lysis_buffer |
A lysochrome is a soluble dye used for histochemical staining of lipids , which include triglycerides , fatty acids , and lipoproteins . Lysochromes such as Sudan IV dissolve in the lipid and show up as colored regions. The dye does not stick to any other substrates, so a quantification or qualification of lipid prese... | https://en.wikipedia.org/wiki/Lysochrome |
The lysocline is the depth in the ocean dependent upon the carbonate compensation depth (CCD), usually around 5 km, below which the rate of dissolution of calcite increases dramatically because of a pressure effect. While the lysocline is the upper bound of this transition zone of calcite saturation, the CCD is the low... | https://en.wikipedia.org/wiki/Lysocline |
The lysophosphatidic acid receptors ( LPARs ) are a group of G protein-coupled receptors for lysophosphatidic acid (LPA) that include:

Lysophosphatidylinositol ( LPI , lysoPI ), or L -α-lysophosphatidylinositol , is an endogenous lysophospholipid and endocannabinoid neurotransmitter . [ 1 ] LPI, along with its 2-arachidonoyl- derivative, 2-arachidonoyl lysophosphatidylinositol (2-ALPI), have been proposed as the endogenous ligands of GPR55 .
