effects of condensed tannins (ct) on crude protein availability in sainfoin hay was investigated according to most popular ruminant feeding systems. different treatments including polyethylene glycol (6000 mw), sodium hydroxide, sodium bicarbonate, potassium permanganate, wood ash, water and urea, were applied for deactivation of ct crude protein fractioning was determined using nylon bag techn...

this study was carried out to determine the protein and carbohydrate molecular structure of sorghum cultivars using fourier transform infrared spectroscopy (ftir) with multivariate molecular spectroscopy analyses. sorghum cultivars included: 1- kimia, 2- sepideh, 3- m2 and 4- m8. protein and carbohydrate molecular functional groups studied included: peak area and height amide i, amide ii, α-hel...

Jujube (Ziziphus jujuba Mill.) fruit is an important medicinal plant in Iran. The harvesting time is a crucial for jujube fruit quality. Several characteristics of jujube fruit when harvested at four development stages; white mature (light green), crisp mature (white-red), fully mature (red) and fully ripe (dehydrated brown) were evaluated. Fruit weight, diameter, volume, pulp to stone ratio, f...

background: leishmania major lmsti1 is a conserved protein among different species of leishmania, and expressed in both amastigote and promastigote forms of l. major life cycle. it has previously been expressed in bacterial systems. m aterials and methods: to express lmsti1 in the methylotrophic yeast         pichia pastoris ( p. pastoris ), the shuttle vector ppicza containing gene lmsti1 was ...

Background: Iran is one of the major consumers of opium and opiate substances in the world. Addiction has become a very important issue in the 21st century and an urgent one in Iran. The consumption of this substance leaves a variety of impacts on the human body. The goal of this study is to investigate the changes of the biochemical parameters derived from opiate substances in addicts during t...

To explore the function of light-harvesting complex protein (LHCP) in Arabidopsis growth and development, the Leclere and Bartel seed collection was screened. In this collection randomly cloned cDNAs are expressed under the CaMV35S promoter. A pale green line has been identified and characterized in more details. Analysis of the inserted cDNA in the pale green line showed it encodes LHCB1 prote...

the study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of japanese quails. a total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (crd) replicated six times. a factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

a proteomic approach was conducted to further understand the mechanism of plant responses to salinity in hordeum bulbosom. three-week-old seedlings were treated with 300 mm of nacl for 21 days. total proteins of fourth leaf were extracted and separated by two-dimensional gel electrophoresis. more than 500 protein spots were reproducibly detected, including 46 spots that were up-regulated and 16...
