HLA-B51
HLA-B51 (B51) is an HLA- B serotype. The serotype identifies the more common HLA-B*51 gene products. B51 is a split antigen of the broad antigen B5, and is a sister serotype of B52. There are many alleles within the B*51 allele group. B51 is associated with several diseases, including Behçet's disease. Serotype Alleles There are 71 alleles, 57 amino acid sequence variants in B51 of which 4 are nulls. Of these only 9 are frequent enough to have been reliably serotyped. B*5101 is the most common, but others have a large regional abundance. Disease associations By serotype Bw51 was associated with Behçet's disease, in endemic (versus epidemic) mucocutaneous lymph node syndrome, susceptibility to the virus that causes German measles infection. In Behçet's disease Behçet's disease is an inflammation of the wall of blood vessels that can involve the eyes, skin, and the rest of the body. Several alleles of B51 (B*5101, B*5108, B*5105, and B*5104) are found in disea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesstraße 51

Martin XB-51
The Martin XB-51 was an American trijet ground-attack aircraft. It was designed in 1945 and made its maiden flight in 1949. It was originally designed as a bomber for the United States Army Air Forces under specification V-8237-1 and was designated XA-45. The "A" ground-attack classification was eliminated the next year, and the XB-51 designation was assigned instead. The requirement was for low-level bombing and close support. The XB-51 lost out in evaluation to the English Electric Canberra which - built by Martin - entered service as the Martin B-57 Canberra. Design and development This unorthodox design, first flying on 28 October 1949, was fitted with three General Electric J47 engines - an unusual number for a combat aircraft - two underneath the forward fuselage in pods, and one at the extreme tail with the intake at the base of the tailfin. The innovative, variable incidence wings, swept at 35° and with 6° anhedral, were equipped with leading edge slats and full-w ...

Sicilian Defence
The Sicilian Defence is a chess opening that begins with the following moves: :1. e4 c5 The Sicilian is the most popular and best-scoring response to White's first move 1.e4. Opening 1.d4 is a statistically more successful opening for White because of the high success rate of the Sicilian defence against 1.e4. '' New In Chess'' stated in its 2000 Yearbook that, of the games in its database, White scored 56.1% in 296,200 games beginning 1.d4, but 54.1% in 349,855 games beginning 1.e4, mainly because the Sicilian held White to a 52.3% score in 145,996 games. 17% of all games between grandmasters, and 25% of the games in the Chess Informant database, begin with the Sicilian. Grandmaster John Nunn attributes the Sicilian Defence's popularity to its "combative nature": "in many lines Black is playing not just for equality, but for the advantage. The drawback is that White often obtains an early initiative, so Black has to take care not to fall victim to a quick attack." Gra ...
