  2. Orexin - Wikipedia

    en.wikipedia.org/wiki/Orexin

    Orexin (/ ɒ ˈ r ɛ k s ɪ n /), also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. [5] It exists in the forms of orexin-A and orexin-B.The most common form of narcolepsy, type 1, in which the individual experiences brief losses of muscle tone ("drop attacks" or cataplexy), is caused by a lack of orexin in the brain due to destruction of the cells ...

  3. Reporter gene - Wikipedia

    en.wikipedia.org/wiki/Reporter_gene

    In molecular biology, a reporter gene (often simply reporter) is a gene that researchers attach to a regulatory sequence of another gene of interest in bacteria, cell culture, animals or plants. Such genes are called reporters because the characteristics they confer on organisms expressing them are easily identified and measured, or because ...

  4. Manganese deficiency (plant) - Wikipedia

    en.wikipedia.org/wiki/Manganese_deficiency_(plant)

    Structure of the Mn 4 O 5 Ca core of the oxygen-evolving site in plants, illustrating one of many roles of the trace mineral manganese. [1] Manganese (Mn) deficiency is a plant disorder that is often confused with, and occurs with, iron deficiency. Most common in poorly drained soils, also where organic matter levels are high.

  5. Plant tissue test - Wikipedia

    en.wikipedia.org/wiki/Plant_tissue_test

    With most types of plant stress, this variable fluorescence can be used to measure the level of plant stress. The most commonly used protocols include: Fv/Fm, a dark adapted protocol, Y(II) or ΔF/Fm’ a light adapted test that is used during steady state photosynthesis, and various OJIP, dark adapted protocols that follow different schools of ...

  6. Orexin receptor - Wikipedia

    en.wikipedia.org/wiki/Orexin_receptor

    Both orexin receptors exhibit a similar pharmacology – the 2 orexin peptides, orexin-A and orexin-B, bind to both receptors and, in each case, agonist binding results in an increase in intracellular calcium levels. However, orexin-B shows a 5- to 10-fold selectivity for orexin receptor type 2, whilst orexin-A is equipotent at both receptors ...

  7. GUS reporter system - Wikipedia

    en.wikipedia.org/wiki/GUS_reporter_system

    The GUS reporter system (GUS: β-glucuronidase) is a reporter gene system, particularly useful in plant molecular biology [1] and microbiology. [2] Several kinds of GUS reporter gene assay are available, depending on the substrate used. The term GUS staining refers to the most common of these, a histochemical technique.

  9. SB-334867 - Wikipedia

    en.wikipedia.org/wiki/SB-334867

    SB-334867 is an orexin antagonist.It was the first non-peptide antagonist developed that is selective for the orexin receptor subtype OX 1, with around 50x selectivity for OX 1 over OX 2 receptors. [1]
