Background: In avian species, the germ line stem cell population arises outside of the embryonic gonad and proceeds on a circuitous migration to the germinal epithelium. Specifically, in the avian embryo, the process of germ line stem cell migration proceeds through a series of active and passive migratory phases. The germline stem cells or primordial germ cells (PGCs) located in the epiblast o...
On the real number line, a point is represented by a real number x if x is finite. Infinity in this setting could be represented by the symbol ∞. However, it is more difficult to calculate with infinity. One way to resolve this issue is through a different coordinate system call homogeneous coordinate. For the real line, this looks a lot like fractions. Instead of using one number x ∈ R, we wil...
In order to investigate the combining ability of sunflowers lines under normal conditions and drought stress, a study was conducted at the Seed and Plant Improvement Institute, Karaj, Iran in 2006. A total of 41 treatments including 2 CMS and 13 restorer lines as well as their 26 corresponding hybrids were evaluated in two irrigation conditions, in a line x tester approach. The analysis of va...
Background: All To enhance the curative effect of radiotherapy, we established a radio-resistant cell line, CNE-2R from CNE-2, a radio-sensitive type of CNE, through repeated irradiation. The developed cell line provides a basis for further studies on the radio-resistance of CNE and the molecular mechanism of radiotherapy sensitization drugs. Materials and Methods: The CNE-2 cell line was selec...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
