HE genome in Escherichia coli K-12 exists normally as one ring of doublestranded DNA (CAIRINS 1963). The fertility factor, F, is responsible for the ability of certain strains to act as genetic donors. F may exist as an autonomously replicating element (in Ff strains) or be integrated into and replicate with bacterial genome (in Hfr strains) (WOLLMAN, JACOB, and HAYES 1956). Multiplication of t...

This paper discusses about the solution of fuzzy Volterra integral equation of first-kind (F-VIE1) using spectral method. The parametric form of fuzzy driving term is applied for F-VIE1, then three classifications for (F-VIE1) are searched to solve them. These classifications are considered based on the interval sign of the kernel. The Gauss-Legendre points and Legendre weights for arithmetics ...

Chromosomal defects are relatively frequent in infertile men however, translocations between the Y chromosome and autosomes are rare and less than 40 cases of Y-autosome translocation have been reported. In particular, only three individuals has been described with a Y;21 translocation, up to now. We report on an additional case of an infertile man in whom a Y;21 translocation was associated wi...

Genetic factors influence renal disease progression, and several loci have been linked to the spontaneous development of proteinuria and glomerulosclerosis in animal models. However, the role of genetic susceptibility in glomerulonephritis-induced progressive glomerulosclerosis is unknown. In a rat model of mesangial proliferative glomerulonephritis, anti-Thy-1 glomerulonephritis (antiThy1GN), ...

Rett syndrome (RTT), caused by mutations in MECP2 (encoding methyl CpG binding protein 2), and Angelman syndrome (AS), caused by maternal deficiency of chromosome 15q11-13, are autism-spectrum neurodevelopmental disorders. MeCP2 is a transcriptional repressor of methylated genes, but MECP2 mutation does not directly affect the imprinted expression of genes within 15q11-13. We tested a potential...

infertility affects approximately 15% of couples worldwide. within 50% of cases, man provides reproductive function disorders (1). the cause of infertility in men with oligospermia and azoospermia seems to be due to underlying genetic abnormalities (2). chromosomal abnormalities are one of the causes of human infertility as they interfere with spermatogenesis. the frequency of chromosomal aberr...
