The structural characterization of proteins using electrospray ionization mass spectrometry (ESI-MS) has become an important method for understanding protein structural dynamics. The correlation between the structures of proteins in solution and gas phase needs to be understood for the application of ESI-MS to protein structural studies. Hen egg white lysozyme (Lyz) is a small protein with a st...

A study was conducted to determine the effect of live weight of partridges on egg production and egg quality characteristics. A total of 144 Rock Partridges were divided into control, heavy, middle, and light BW groups at 32 wk of age. Live weights averaged 512.78 g for the control group, 576.18 g for the heavy group, 523.49 g for the middle group, and 473.83 g for the light group. Egg producti...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Recently, a novel environmental stress index (ESI) which is composed from commonly used meteorological variables: ambient temperature (T(a)), relative humidity (RH), and solar radiation (SR) was suggested as follows: ESI = 0.63T(a)-0.03RH+0.002SR+0.0054(T(a) x RH)-0.073(0.1+SR)(-1); (degrees C) The purpose of the present study was to evaluate and validate the ESI for hot dry and hot wet climati...

Eggs are an important and convenient source of protein for those living in rural regions. In addition, eggs from local hens popular traded a fair price. As result, the primary goal this study was to evaluate egg laying quality parameters Sakini (Gallus gallus domesticus) Nepal order better understand chicken’s reproductive fitness relationship between parameters. For this, total 120 different w...

an experiment employing a factorial arrangement of three levels (0, 8 and 16%) of canola meal (cm), two levels (0.15 and 0.25%) of nonphytate phosphorus (npp), and two levels (0 and 450 unit/kg; as fed basis) of microbial phytase was conducted using 216 hy-line w36 laying hens from 39 to 47 weeks of age. the birds receiving cm consumed more (p < 0.05) feed than birds receiving corn-soybean meal...

Egg yolk phospholipids from seven different species were purified (purity > 96%) using SPE columns, and subsequently the phospholipid profiles identified quantified by ultra-high-performance liquid chromatography-electrospray ionization-triple time-of flight mass spectrometry (UHPLC-ESI-Triple TOF-MS). Eight classes 87 molecular characterized. Principal component analysis showed that concentrat...

the aim of the present research is to study scientometric indicators (the number of articles and citations, the mean citation per paper, h-index, y-index, and the national and international collaboration) of medical and non-medical highly cited papers of iran in the essential science indicators (esi). the research population is all highly cited articles of iran in esi during 2005 to 2015. data ...
