Broken rice (BR) is one of the important by-products of rice production, which is produced in large scales in northern provinces of Iran. An experiment was conducted to investigate the effect of different levels of BR on egg quality and performance of laying hen, with 5 levels of BR (0, 10, 20, 30 and 40%) in a completely randomization design (CRD) on 90 Hy-line W36 egg-type laying hens f...
THE advance of scientific knowledge is a combined early differentiation of the Drosophila egg chamber in product of both the contributions of the individual the 1960s. Through painstaking three-dimensional (3D) scientist and the acceptance and authentication of his reconstructions of serially sectioned egg chambers, they or her work over time by the larger scientific community. deciphered the p...
Supernumerary centrosomes are a key cause of genomic instability in cancer cells. New centrioles can be generated by duplication with a mother centriole as a platform or, in the absence of preexisting centrioles, by formation de novo. Polo-like kinase 4 (Plk4) regulates both modes of centriole biogenesis, and Plk4 deregulation has been linked to tumor development. We show that Plx4, the Xenopus...
Global warming has substantially changed the environment, but the mechanisms to cope with these changes in animals, including the role of maternal effects, are poorly understood. Maternal effects via hormones deposited in eggs, have important environment-dependent effects on offspring development and fitness: thus females are expected to adjust these hormones to the environment, such as the amb...
