The role of the male factors during the process of recurrent miscarriage has not been known and need further discussing. The male factors involved in the occurrence of adverse pregnancy outcomes may include: chromosom...

The TOPINV, Topological Inversion algorithm (or TGS, Topological Grid Search) initially developed for the inversion of highly non-linear redundant systems of equations, can solve a wide range of underdetermined systems of non-linear equations. This approach is a generalization of a previous conclusion that this algorithm can be used for the solution of certain integer ambiguity problems in Geod...

Morphological abnormalities of the X chromosome are well documented and have been extensively reviewed and discussed by Ferguson-Smith (1965). They include isochromosome of the long arm, deletions of the long and short arms, ring chromosomes, and chromosomal fragments. Other types of abnormality are rare. Engel and Forbes (1965) described a chromatin negative girl (Patient No. 27) with a mosaic...
