The reactive cysteines in H-ras are subject to oxidative modifications that potentially alter the cellular function of this protein. In this study, purified H-ras was modified by thiol oxidants such as hydrogen peroxide (H(2)O(2)), S-nitrosoglutathione, diamide, glutathione disulphide (GSSG) and cystamine, producing as many as four charge-isomeric forms of the protein. These results suggest tha...

This is an article about children's deafness, it's ethiology, diagnosis, treatment, and educa­tional treatment. Here I have given a brief account about the deafness itself and it's in­dividual and social complications, also it's im­pression on the psychological well baing of the child. Then I have discussed, rather in detail, the ethiology of .children's deafness and I have given some statistic...

In this paper, we have dened and studied a generalized form of topological vector spaces called s-topological vector spaces. s-topological vector spaces are dened by using semi-open sets and semi-continuity in the sense of Levine. Along with other results, it is proved that every s-topological vector space is generalized homogeneous space. Every open subspace of an s-topological vector space is...
