(FceRI) on the cell surface which plays a pivotal role in the development of allergic inflammation. FceRI is mainly expressed on mast cells and basophils as a tetramer of one a , one b and g chain homodimers. Aggregation of the FceRI on mast cells by bound IgE and multivalent antigens induces rapid release of preformed intragranular mediators such as histamine and heparin, newly synthesis of ar...

Fungal nitric-oxide reductase (NOR) is a heme enzyme that catalyzes the reduction of NO to N(2)O through its ferric-NO complex, the first intermediate of the catalysis. Crystal structures of the ferric-NO forms of wild type (WT) fungal NOR, and of the Ser(286) --> Val and Ser(286) --> Thr mutant enzymes were determined to 1.7-A resolution at cryogenic temperature (100 K). This shows a slightly ...

Since Grice (1952) published his report of subtalar extra-articular arthrodesis, and later (1955) described his results in fifty-two cases, this operation has been widely used. In 1957 Westin and Hall published a preliminary report of sixty-two extra-articular arthrodeses in patients from three to twelve years of age with paralytic pes planus and pes calcaneo-valgus. Malvarez (1957) reported hi...
