HgII interacting with a naturally ZnII-containing Rad50 protein interface yields HgS4 species, the strongest metal–protein interaction known to date. It also introduces novel manifestation of mechanism prokaryotic and eukaryotic cells. Furthermore, substitution occurring ZnII possibly has an impact on quaternary structure assembly process, thus disrupting DNA-repair mechanisms that engage Mre11...

A general single-step approach is introduced for the green fabrication of hybrid biosensors from water dispersion. The resulting device integrates semiconducting properties a carbon nanotube (CNT) and functionality protein. In initial aqueous phase, protein (viz., lysozyme [LZ]) disperses (6,5)CNT. Drop-casting dispersion on test pattern (a silicon wafer with interdigitated Au source drain elec...

An experiment was carried out to compare the milk production of Friesian cows grazing perennial ryegrass pastures when fed an energy supplement or supplements with high levels of undegradable protein. Eighty-seven cows were blocked on the basis of calving date and milk yield and allocated to one of three treatments. The treatments consisted of 1.25 kg/day of concentrates based predominantly on ...

the aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (pbpm) fed during late gestation on the performance, blood metabolites, and colostrum composition of holstein dairy cows. sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1) 14% and 2) 16% crude protein. the cow’s bcs was 3.56 ...

in order to evaluation of genotype by environment interactions in holstein cows, iran was divided into cold, middle cold, temperate and hot climate regions. for this purpose used from 39570, 35813 and 18955 records for milk, fat and protein yields, respectively, to progeny test for 35 sires that have 50 daughters in each climate. the data were collected by the centre of breeding and improvement...
