Nori (æµ·è) is the Japanese name for edible seaweed species of the red algae genus Porphyra, including P. yeeziensis and P. tenera.Nori is familiar in the United States and other countries as an ingredient of sushi, being referred to as nori (as the Japanese do) or simply as seaweed.Finished products are made by a shredding and rack-drying process that resembles papermaking. common secondary product is toasted and flavored nori (ajitsuke-nori), in which a flavoring mixture (variable, but typically soy sauce, sugar, sake, mirin, and seasonings) is applied in combination with the toasting process. It is also eaten by making it into a soy sauce-flavored paste, nori no tsukudani (æµ·èã®ä½ç®).
There are two major types of the human immunodeficiency virus. HIV-1, which was discovered first, is the most widespread type worldwide. HIV-2 is more than 55% genetically different from HIV-1.IV-1 and HIV-2. 1  HIV-1 and HIV-2 are the two main types of HIV. 2  HIV-1 is the most widespread type worldwide. 3  Large genetic differences between HIV-1 and HIV-2 mean that tests keyed to one will not reliably detect the other.
The HIV virus infects cells with CD4 surface proteins, and as a result, depletes the number of immune system cells (T cells, B cells, natural killer cells, monocytes) in the individual's blood. Most of the damage to an AIDS patient's immune system is done by the virus' destruction of CD4+ lymphocytes.IDS is the advanced form of infection with HIV virus. This virus may not cause recognizable symptoms for a long period after the initial exposure (latent period). As of early 2009, no vaccine was available to prevent HIV infection.
