The objective of this study was to estimate genetic parameters for milk protein fraction contents, milk protein composition, and milk coagulation properties (MCP). Contents of α(S1)-, α(S2)-, β-, γ-, and κ-casein (CN), β-lactoglobulin (β-LG), and α-lactalbumin (α-LA) were measured by reversed-phase HPLC in individual milk samples of 2,167 Simmental cows. Milk protein composition was measured as...

BACKGROUND The cn/cn dwarf mouse is caused by a loss-of-function mutation in the natriuretic peptide receptor 2 (NPR-2) gene which helps positively regulate endochondral longitudinal bone growth. The gene mutation corresponds to that in the human skeletal dysplasia Acromesomelic Dysplasia Maroteaux type (AMDM). This study assesses histomorphometric, ultrastructural and radiographic correlates o...

Alpha s1-, alpha s2-, beta- and kappa-caseins from Somali camels (Camelus dromedarius) were purified by acid precipitation at pH 4.4, crudely separated into an alpha-CN and a beta-CN fraction and further purified by reversed-phase HPLC. Fragments of tryptic digests were sequenced. Amino acid patterns obtained were used to screen a cDNA library constructed from mRNA from lactating udder tissue. ...

Cyanoborane adducts of the Lewis acids B(CN)3, BF(CN)2, and BH(CN)2 with pyridine 4-cyanopyridine have been obtained in high yields. The syntheses were accomplished by oxidation readily available potassium salts cyano(hydrido)borate anions [BH(CN)3]− (MHB), [BFH(CN)2]− (FHB), [BH2(CN)2]− (DHB) bromine presence respective derivative C5H5N or 4-CN-C5H4N as starting material. All six cyanoborane c...

A new fast and reliable reversed-phase high-performance liquid chromatographic method is proposed for quantifying all the major casein fractions during cheese proteolysis as an alternative to more complex methodologies. Excellent separation of caseins, para-κ-casein (ρ-κ-CN), αs1-casein (αs1-CN), αs1-I-casein (αs1-I-CN), αs2-casein (αs2-CN), β-casein (β-CN) was achieved, in terms linearity, rep...

the main goal of this paper is to propose a new practical method for hydrologic soil group estimation in surface runoff process based on geomorphology facieses and slop. the determination of cn based on this method can reduce the time and cost of project. in this research the upstream rivers of glinak watershed have been used as a case study to examine the efficiency of proposed method with a c...
