Nerve Growth Factor
Nerve growth factor (NGF) is a neurotrophic factor and neuropeptide primarily involved in the regulation of growth, maintenance, proliferation, and survival of certain target neurons. It is perhaps the prototypical growth factor, in that it was one of the first to be described. Since it was first isolated by Nobel Laureates Rita Levi-Montalcini and Stanley Cohen in 1956, numerous biological processes involving NGF have been identified, two of them being the survival of pancreatic beta cells and the regulation of the immune system. Structure NGF is initially in a 7S, 130-kDa complex of 3 proteins – Alpha-NGF, Beta-NGF, and Gamma-NGF (2:1:2 ratio) when expressed. This form of NGF is also referred to as proNGF (NGF precursor). The gamma subunit of this complex acts as a serine protease, and cleaves the N-terminal of the beta subunit, thereby activating the protein into functional NGF. The term ''nerve growth factor'' usually refers to the 2.5S, 26-kDa beta subunit of the protein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Gunfire Support
Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics NGFS is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines due to a predictable and steady (non-evasive) cou ...

Northern Group Of Forces
The Northern Group of Forces (; ) was the military formation of the Soviet Army stationed in People's Republic of Poland, Poland from the end of World War II, Second World War in 1945 until 1993 when they were withdrawn in the aftermath of the fall of the Soviet Union. Although officially considered Polish allies under the Warsaw Pact treaty, they were seen by some Poles as a Soviet occupation force. History Early years Soviet forces entered Poland as they were advancing towards Nazi Germany in the course of the Red Army's Operation Bagration in the summer of 1944. Following the Vistula-Oder Offensive in early 1945, all of Poland was liberated from Nazi occupation by Soviet forces. While formal Polish sovereignty was almost immediately restored, the territory of Poland fell under ''de facto'' Soviet control as the Soviet military and security forces acted to ensure that Poland would be ruled by the Soviet-installed Polish Committee of National Liberation, communist puppet govern ...

National Golf Foundation
The National Golf Foundation (NGF) provides golf-business research and consulting services. Founded in 1936 by golf writer Herb Graffis and his brother Joe, who nearly went bankrupt in the process, its original mission was to publish authoritative research useful to investors developing the game of golf. it had 6000 member companies.

Folliculogenesis
:''Although the process is similar in many animals, this article will deal exclusively with human folliculogenesis.'' In biology, folliculogenesis is the maturation of the ovarian follicle, a densely packed shell of somatic cells that contains an immature oocyte. Folliculogenesis describes the progression of a number of small ''primordial follicles'' into large '' preovulatory follicles'' that occurs in part during the menstrual cycle. Contrary to male spermatogenesis, which can last indefinitely, folliculogenesis ends when the remaining follicles in the ovaries are incapable of responding to the hormonal cues that previously recruited some follicles to mature. This depletion in follicle supply signals the beginning of menopause. Overview The primary role of the follicle is oocyte support. From the whole pool of follicles a woman is born with, only 0.1% of them will rise ovulation, whereas 99.9% will break down (in a process called follicular atresia). From birth, the ovaries of ...

North German Federation
The North German Confederation (german: Norddeutscher Bund) was initially a German military alliance established in August 1866 under the leadership of the Kingdom of Prussia, which was transformed in the subsequent year into a confederated state (a ''de facto'' federal state) that existed from July 1867 to December 1870. A milestone of the German Unification, it was the earliest continual legal predecessor of the modern German nation-state known today as the Federal Republic of Germany. The Confederation came into existence following the Prussian victory in the Austro-Prussian War of 1866 over the lordship of two small Danish duchies (Schleswig-Holstein) resulting in the Peace of Prague, where Prussia pressured Austria and its allies into accepting the dissolution of the existing German Confederation (an association of German states under the leadership of the Austrian Empire), thus paving the way for the Lesser German version of German unification in the form of a federa ...
