Nickel Increases Chromosomal Abnormalities by Interfering with the Initiation of DNA Repair Pathways

Background: Nickel is a carcinogenic, heavy metal released through industrial activities and via natural resources. It is able to cause DNA damages by reducing the efficiency of DNA repair mechanisms. However, the exact time point at which it is able to interfere with these mechanisms is not yet clearly understood. Methods: To find the most nickel-vulnerable time of repair mechanisms, human de...

Quality assessment of conventional X-ray diagnostic equipment by measuring X-ray exposure and tube output parameters in Great Khorasan Province, Iran

Introduction: Regular implementation of quality control (QC) program in diagnostic X-ray facilities may affect both image quality and patient radiation dose due to the changes in exposure parameters. Therefore, this study aimed to investigate the status of randomly selected conventional radiographic X-ray devices installed in radiology centers of Great Khorasan Province, Iran, to produce the da...

Induced Changes in Female Germ Cells of Drosophila. VII. Exchanges Induced in Different X Chromosome Regions after X-Raying Oocytes and Oogonia.

OME of the earlier papers in this series (HERSKOWITZ and ABRAHAMSON 1957; S H ~ ~ ~ ~ ~ ~ ~ ~ ~ 1959) were concerned with the detection of X-ray-induced exchanges in germ cells of female Drosophila melanogaster. It was found in the proximal portion of the X chromosome, i.e., the region between the right end of the chromosome and the locus of carnation, that X-ray exposure induced exchanges both...

Integrin Linked Kinase (X-ILK) Function during Embryonic Development and within Adult Tissues of Xenopus laevis

Integrin linked kinase (ILK) is a serine/threonine protein kinase implicated in the phosphatidylinositol 3’kinase (PI3’K) pathway. Integrin linked kinase has been investigated in different organisms such as mammalian systems (human, mice, rat), insects (Drosophila) and nematodes (Cenorhabditis elegans), however to date little data regarding ILK research on amphibians has been reported. In...
