the aim of this study was to estimate the genetic and phonotypic trends of somatic cell score in iranian holstein cows. also, the environmental factors affecting this trait are investigated. a total of 375351 test day records of somatic cells take from 54374 animals between year 2002 and 2007 were used in this study. the breeding values were estimated by fitting animal model in asreml software....

in this study test-day records of milk (kg), fat (g), and protein (g) yields, somatic cell score (scs, cells/ml) collected by animal breeding center of iran during 2007 and 2009 were used to estimate genetic parameters using random regression model. models with different order of legendre polynomials were compared using bayesian information criterion (bic).for milk, fat yield and scs genetic an...

the effect of in planta tiba and proline on in vitro seedlings and cell culture of sugar beet was investigated. sterilized seeds were grown in vitro on ½ strength ms medium supplemented with 0 or 3 mg/l tiba. calli obtained on young leaves cultured on ms medium containing 1 mg/l bap, were used for the intiation of cell suspension cultures using ms basal composition supplemented with 0 or 50 m m...

Background: For several years, mammalian cloning by splitting an early embryo or nuclear transfer into oocytes method has been successfully performed. Cloning is now also possible using adult somatic cells. Although it has now been 15 years since the first cloned mammals were generated from somatic cells using nuclear transfer (NT), the success rate for producing live offspring by cloning is lo...

background: inverse relationship between helminths infection and immune-mediated diseases has inspired researchers to investigate therapeutic potential of helminths in allergic asthma. helminth unique ability to induce immunoregulatory responses has already been documented in several experimental studies. this study was designed to investigate whether excretory/secretory (es) and somatic produc...

background: epigenetic reprogramming of differentiated cells can modify somatic cells into pluripotential state. pluripotency can be induced in somatic cells by several approches. one of the easy ways to induce pluripotency is the exposure of the somatic cells to the embryonic stem cell (esc) extract. objective: the objective of this study was to increase the efficiency of reprogramming of gran...
