Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...

background: previous studies have revealed significant differences between populations for genotypic frequencies of glutathione s-transferase t1 ( gstt1 ) and m1 ( gstm1 ) polymorphisms. in order to find the frequency of the null genotypes of gstm1 and gstt1 in iranian populations, the present study was carried out. methods: the total study subjects consisted of 1340 unrelated healthy muslims/i...

as this is an editorial, don't need the abstract.

Neutrosophic Genetics is the study of genetics using neutrosophic logic, set, probability, statistics, measurement, and other tools procedures. In this paper, based on Theory Evolution (that includes degrees Evolution, Neutrality (or Indeterminacy), Involution) – as an extension Darwin’s we show applicability neutrosophy in genetics, present within frame following concepts: mutation, speciation...

spherical equivalent (se) has not been linked to increased cardiovascular morbidity. methods: 132 hungarian twins (age 43.3±16.9 years) underwent refraction measurements (huvitz mrk-3100 premium autorefractokeratometer) and oscillometry (tensiomed arteriograph). results: heritability analysis indicated major role for genetic components in the presence of right and left se (82.7%, 95%ci, 62.9 to...

introduction: pathophysiology of cancer is based on genetic instabilities. this can explain recent important role of genetic studies in such diseases. defects can be large (on molecular scale) at the level of chromosomal or small in nucleotide level, which eventually causes to irreversible change in the cell. conventional technical methods in cancer genetics are generally based on molecular or ...

background: essential hypertension tends to a familial mode. its pattern of inheritance is heterogeneous, but the frequencies of different mode of inheritance vary in different populations. determining of the mode of inheritance in each family is the basic information that is needed for the risk estimation in those family members. determination of pattern of inheritance in families with at leas...
