in recent years most activities of rice research institute, has been focused on introduction of high yielding as well as high quality rice cultivars. in 1994, 185 lines introduced from international rice research institute (irri) to rice research institute of iran (rrii), were evaluated in observational and statistical experiments in rrii for two years, and eight lines were selected. these line...
X inactivation makes females mosaics for 2 cell populations, usually with an approximate 1:1 distribution. Skewing of this distribution in peripheral blood cells is more common among elderly women. The depletion of hematopoietic stem cells followed by random differentiation may explain the acquired skewing with age. However, an animal model suggests that selection processes based on X-linked ge...
This paper considers the problem of estimating the population mean Ybar of the study variate Y using information on different parameters such as population mean $(bar{X})$, coefficient of variation $(C_x)$, kurtosis $beta_{2(x)}$, standard deviation $(S_x)$ of the auxiliary variate x and on the correlation coefficient, $rho$, between the study variate $Y$ and the auxiliary variate $...
optimization of gene transfection in murine myeloma cell lines using different transfection reagents
purification and isolation of cellular target proteins for monoclonal antibody (mab) production is a difficult and time-consuming process. immunization of mice with murine cell lines stably transfected with genes coding for xenogenic target molecules is an alternative method for mouse immunization and mab production. here we present data on transfection efficiency of some commercial reagents us...
A better understanding of the mechanism of chromosomal aberration formation could be obtained by using DNA repair inhibitors. Immortalized normal human (MRC 5 SVI) and ataxia telangiectasia ( AT 5 BIV A ) fibroblastic cell lines were treated with adenosine arabinoside (ara-A) and cytosine arabinoside (ara-C), both potent inhibitors of DNA dsb repair, alone or in combination with x-rays at ...
The experiment was arranged based on a completely randomized block design, with two replicates in hydroponic conditions at The University of Zabol in 2013.In present study, 72 barley double haploid lines along with two parents were experimented. The measured traits including: fresh and dry weight of root and shoot and their ratio, length of root and shoot and their ratio, length of the lar...
general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...
