In this paper we investigate the automorphisms of a family small (q,8)-graphs order 2q3 − 2q which are obtained as induced subgraphs incidence graph classical generalized quadrangle q. We show that for q an odd prime power, automorphism group has four orbits on set vertices, thus investigated graphs cannot be Cayley or lifts dipole.

Oguchi disease is a rare autosomal recessive form of congenital stationary night blindness. The condition is associated with fundus discolouration and abnormally slow dark adaptation. Earlier studies suggested that the 48 kD protein S antigen may be involved in the recovery phase of light transduction. Previous cytogenetic and linkage studies have localised the S antigen gene (SAG) to chromosom...

OBJECTIVE To search for genetic association between microsatellite marker loci and sibling pairs with nodal osteoarthritis (NOA). METHODS Using the affected sibling pair method of analysis, genomic DNA from 66 sib pairs with NOA was analysed for association with highly polymorphic microsatellite marker loci. The microsatellite markers were amplified using polymerase chain reaction and typed o...

this case report presents a case of fanconi’s anemia with an unusual thumb polydactyly in a 2-year old boy. the extra thumb had no nail, nail bed and distal phalanx. the extra thumb had no active motion.the duplication of the thumb occurred at the carpometacarpal joint but its morphology did not match with any classification described for thumb polydactyly. although his thumb polydactyly was ap...

introduction: the secondary genetic changes other than the pml-rara fusion gene may contribute to the acute promyelocytic leukemogenesis. chromosomal alterations and mutation of flt3 tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia (aml). however, the prognostic significance of flt3 mutations in acute promyelocytic leukemia (apl) is not firmly established....

In a path-breaking paper last year Pat and Betty O'Neil and Gerhard Weikum proposed a self-tuning improvement to the Least Recently Used (LRU) buuer management algorithmm15]. Their improvement is called LRU/k and advocates giving priority to buuer pages based on the kth most recent access. (The standard LRU algorithm is denoted LRU/1 according to this terminology.) If P1's kth most recent acces...

In this work, we investigate the transfer of some homological properties from a ring $R$ to its amalgamated duplication along some ideal $I$ of $R$ $Rbowtie I$, and then generate new and original families of rings with these properties.

We report a female infant diagnosed shortly after birth as having Smith-Lemli-Opitz syndrome. Despite previously reported normal G banded karyotypes, a high resolution banded chromosome analysis identified 46,XX,2q+. The importance of attention to established features of clinical syndromes, as well as persistence in investigation when diagnostic uncertainties exist, are discussed.
