Aim: The objective of this study was to develop a simplified, efficient, and accurate protocol for sexing of cattle meat based on the amelogenin (AMELX/AMELY) gene using PCR technique which is superior to earlier work in terms of band patterns. Materials and Methods: Based on the amelogenin gene located on the conservation region of X and Y chromosomes, a pair of primers was designed and the sy...

DNA repair efficiency varies among individuals, with reduced repair capacity as a risk factor for various cancers. This variability could be partly explained by allelic variants for different DNA repair genes. We examined the role of a common polymorphism in the XRCC3 gene (codon 241: threonine to methionine change) and bladder cancer risk. This gene plays a role in the homologous recombination...

A panel of monoclonal antibodies (MAbs) to P-glycoprotein was developed by immunization of mice with multidrug-resistant human neuroepithelioma and neuroblastoma cells. All the anti-P-glycoprotein MAbs reacted with the extracellular portion of P-glycoprotein. The MAbs were examined for their ability to enhance accumulation of actinomycin D, vincristine, vinblastine, and doxorubicin in the human...

Obtaining Pu background data in the environment is essential for contamination source identification and assessment of environmental impact of Pu released from the Fukushima Daiichi nuclear power plant (FDNPP) accident. However, no baseline information on Pu isotopes in Fukushima Prefecture has been reported. Here we analyzed 80 surface soil samples collected from the central-eastern Japan duri...

A detailed and comprehensive map of the distribution patterns for both natural and artificial radionuclides over Antarctica has been established. This work integrates the results of several decades of international programs focusing on the analysis of natural and artificial radionuclides in snow and ice cores from this polar region. The mean value (37+/-20 Bq m(-2)) of (241)Pu total deposition ...

Abstract The industrial production of 3D printing is known as additive manufacturing (AM), in which a computer controls the process producing objects. Although x-ray computed radiography (XCT) extensively used quality control and testing products, gamma-ray capabilities for these applications still need to be investigated. This study aimed evaluate performance using americium-241 (Am-241) gamma...
