Multivalued SK-contractions with respect to b-generalized pseudodistances

A new class of multivalued non-self-mappings, called SK-contractions with respect to b-generalized pseudodistances, is introduced and used to investigate the existence of best proximity points by using an appropriate geometric property. Some new fixed point results in b-metric spaces are also obtained. Examples are given to support the usability of our main result

Study of HLA-A, B, C alloantigens in a population of the Isfahan province

A random panel of 500 healthy unrelated subjects from Isfahan province were HLA typed for A, B and C locus antigens. The lymphocytes were separated from 5 ml of whole peripheral blood and HLA-A, B, C typing were performed on them, using the standard two stage microlymphocytotoxic NIH technique. The antigens HLA-A1, A2, A3, A9, HLA-B5, B35, HLA-CW4 had the higher frequency than other HLA antigens among the population studied. The distribution of HLA class I antigens in Isfahan is similar with their distribution in Tehran and Mashhad
