Trichophyton concentricum causes Malabar itch, a skin infection consisting of an eruption of a number of concentric rings of overlapping scales forming papulosquamous patches.
Nigiri sushi is a type of Japanese dish made with sushi rice and fresh fish. The sushi rice is hand formed into a small clump, and the fish is sliced and pressed on top of it. In some cases, nigiri sushi uses a small strip of toasted seaweed called nori to bind the whole mixture together, although this is not obligatory.
Nori (æµ·è) is the Japanese name for edible seaweed species of the red algae genus Pyropia, including P. yezoensis and P. tenera. It is used chiefly as an ingredient (wrap) of sushi. Finished products are made by a shredding and rack-drying process that resembles papermaking.
