rooster`s eye has been used a lot in shahnameh and other contexts. poets and authors, following their ancestors, have talked about it as a symbol of beautification, purity, and redness however rooster`s eye doesn’t have any of these features, nor are these features important enough to be noticed by poets. researchers have mentioned some opinions to match these features with rooster`s eye, and...

Composition and thermotropic phase behavior of sperm membrane lipids from species ranging in sensitivity to cold shock were determined. Lipids from whole sperm and sperm plasma membrane were fractionated into neutral lipid, glycolipid, and phospholipid fractions. Compositional analyses were completed for free sterols, phospholipids and phospholipid-bound fatty acids. Phase transition temperatur...

The "cock-a-doodle-doo" crowing of roosters, which symbolizes the break of dawn in many cultures, is controlled by the circadian clock. When one rooster announces the break of dawn, others in the vicinity immediately follow. Chickens are highly social animals, and they develop a linear and fixed hierarchy in small groups. We found that when chickens were housed in small groups, the top-ranking ...

Collagen associated hydrolysates have desirable characteristics for various industrial applications [1,2]. They have been used as important biomaterial in medical applications because of their biodegradability and weak antigenicity [3]. In addition, intracellular and extra-cellular self-assembly of polypeptide chains and the cross-links between adjacent molecules help collagen fibrils to withst...

Sixteen meat and bone meal (MBM) samples were obtained and selected from various company plants to provide a wide range in pepsin nitrogen digestibility values. Pepsin digestibility was determined using either 0.02 or 0.002% pepsin. Amino acid (AA) digestibility of the 16 MBM samples was then determined using a precision-fed cecectomized rooster assay. The 0.02% pepsin digestibility values were...

We have previously shown that in vivo estradiol-dependent dephosphorylation of MDBP-2-H1 (a member of the histone H1 family) correlates with the loss of in vitro preferential binding to methylated DNA. To study the effects of the phosphorylation/dephosphorylation of MDBP-2-H1 on the expression of the avian vitellogenin II gene, we optimised an in vitro transcription system using HeLa nuclear ex...

This study was conducted to determine caeca micro flora and tannin effects on amino acid availability (AAA) values for different grain sorghum cultivars (GSC). Three GSCs including low tannin (0.09%, LTS), medium tannin (0.19%, MTS) and high tannin (0.37%, HTS) were selected to determine AA availability compare to the corn by using the true metabolizable energy (TME) assay with both intact (INT...
