Linear energy transfer (LET) is an important parameter for ion beam mutagenesis. We irradiated rice seeds with carbon ions (LET: 23, 30, 50, or 57 keV µm−1), neon 63 70 argon 290 µm−1). subsequently isolated 56 mutants and analyzed the mutations in responsible genes mutant phenotypes to evaluate effects of different LETs rice. Mutations were classified as single nucleotide variants, small delet...

Sexual ambiguity commonly known as intersexuality, is a condition of imperfect sexual differentiation between male and female. The present study was aimed at analyzing the chromosomal abnormalities of intersex subjects in Coimbatore city, India Of the 30 intersex cases studied, 10 of them were genetically male (46,XY) but phenotypically females, 8 of them were genetically female (46,XX) with ma...

this study determines the value of linkage analysis using six rflp markers for carrier detection and prenatal diagnosis in familial dmd/bmd cases and their family members for the first time in the iranian population. we studied the dystrophin gene in 33 unrelated patients with clinical diagnosis of dmd or bmd. subsequently, we determined the rate of heterozygosity for six intragenic rflp marker...

We describe a criterion for showing that the equation s2+y2p = α3 has no non-trivial proper integer solutions for specific primes p > 7. This equation is a special case of the generalized Fermat equation xp + yq + zr = 0. The criterion is based on the method of Galois representations and modular forms together with an idea of Kraus for eliminating modular forms for specific p in the final stage...

background: wide range of disorders ranging from genetic disorders to coital difficulties can influence male fertility. in this regard, genetic factors are highlighted as the most frequent, contributed to 10-15%, of male infertility causes. objective: to investigate the influence of genetic abnormalities on semen quality and reproductive hormone levels of infertile men from northeast china. mat...
