deCODE discovers cause of major subtype of glaucoma
...pear to account for virtually all cases of a major subtype
of glaucoma. The SNPs are located in the LOXL1 gene on chromosome 15, and confer respectively 26-fold and 8-fold increases in risk of exfoliation glaucoma compared to the low-risk versions of the same markers. Approximately 25% of those in the Icelan...

H5N1 was first detected in poultry in November 1996 in south-east China. The virus subsequently dispersed throughout most of Asia, and also to Africa and Europe. From mid-2005, migratory wild birds have been widely considered to be the primary source...
