Alpha-7 Nicotinic Receptor
The alpha-7 nicotinic receptor, also known as the α7 receptor, is a type of nicotinic acetylcholine receptor implicated in long-term memory, consisting entirely of α7 subunits.Pharmacology, (Rang, Dale, Ritter & Moore, , 5th ed., Churchill Livingstone 2003) p. 138. As with other nicotinic acetylcholine receptors, functional α7 receptors are pentameric .e., (α7)5 stoichiometry">stoichiometry.html" ;"title=".e., (α7)5 stoichiometry">.e., (α7)5 stoichiometry It is located in the brain, spleen, and lymphocytes of lymph nodes where activation yields Excitatory postsynaptic potential, post- and excitatory presynaptic potential, presynaptic excitation, mainly by increased Ca2+ permeability. Further, recent work has implicated this receptor as being important for generation of adult mammal neurons in the retina. Functional α7 receptors are present in the submucous plexus neurons of the guinea-pig ileum. Medical relevance Recent work has demonstrated a potential role in red ...

CHRNA7
Neuronal acetylcholine receptor subunit alpha-7, also known as nAChRα7, is a protein that in humans is encoded by the ''CHRNA7'' gene. The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAchR). Function The nicotinic acetylcholine receptors (nAChRs) are members of a superfamily of ligand-gated ion channels that mediate fast signal transmission at synapses. The nAChRs are thought to be hetero-pentamers composed of homologous subunits. The proposed structure for each subunit is a conserved N-terminal extracellular domain followed by three conserved transmembrane domains, a variable cytoplasmic loop, a fourth conserved transmembrane domain, and a short C-terminal extracellular region. The protein encoded by this gene forms a homo-oligomeric channel, displays marked permeability to calcium ions and is a major component of brain nicotinic receptors that are blocked by, and highly sensitive to, alpha-bungarotoxin. Once this receptor binds acety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpha 7 (Power Rangers)
''Power Rangers Wild Force'' is the 2002 Power Rangers season that tells the story of the Wild Force Power Rangers and their fight against the Orgs. Wild Force Power Rangers The Wild Force Rangers are granted mystical powers and charged to protect the Earth from pollution-created creatures called Orgs. More specifically, they defend the fictional city of Turtle Cove, and are stationed aboard a flying island called the Animarium. Their mentor is Princess Shayla, and her mentor is Animus (an ancient Megazord). The Rangers represent the Ancient Animarium Warriors who also fought to destroy the Orgs and saved the Earth. The Rangers morph using devices known as Growl Phones, which can also act as regular cell phones for communication purposes. Each Ranger is also armed with a Crystal Saber (into which an Animal Crystal is inserted to call a Wild Zord). In addition to piloting their Wild Zords, the Rangers pilot other vehicles, like the Soul Bird and the Savage Cycles. When the Rangers ...

Alpha 7 (Minolta)
The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and had a longer flange focal distance making old manual lenses incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before. The Minolta A-mount system was at first marketed as Maxxum in North America and α (Alpha) in Japan and the rest of Asia. In Europe, early Minolta A-mount cameras were initially identi ...

Alpha-7 Digital
The Maxxum 7D, labelled Dynax 7D in Europe/Hong Kong and α-7 Digital in Japan and officially named "DG-7D", is a 6.1 megapixel digital single-lens reflex camera, or DSLR, produced by Konica Minolta. It was the top model of their DSLR range; the Maxxum/Dynax 5D consumer-grade model was the other. The 7D was first announced on 2004-02-12 at the PMA show, with full details released just before the 2004 photokina show on 2004-09-15. The production camera was released in late 2004. Production ceased when Konica Minolta announced their exit from the camera business in January 2006. Regardless of its high specification (for the time) and innovative feature set, it came with a very high price tag. The 7D was available as body only, but also with a kit lens; a 17-35mm 2.8. Like the Nikon 18-70 kit lens found with many Nikon DSLRs, this lens was regarded as of high enough quality to do justice to the sensor within the body, unlike the cheap zoom kit lenses found with many DSLRs.

Alpha (uppercase , lowercase ; grc, ἄλφα, ''álpha'', or ell, άλφα, álfa) is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph , which is the West Semitic word for " ox". Letters that arose from alpha include the Latin letter A and the Cyrillic letter А. Uses Greek In Ancient Greek, alpha was pronounced and could be either phonemically long ( ː or short ( .
