Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...
the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...
Evaluation of sterility stability between male sterile lines for favorite lines selection is necessary to production of hybrid rice program. So that in present research utilization of 7 cytoplasmic male sterile lines (A line) and 33 male sterile lines product of 7th backcrosses of Iranian varieties with IRRI standard male sterility lines. Experiment was based on a split plot to time design in R...
Structural steel sections are mainly used in beams and columns of building frames. Iran National Steel IndustrialGroup is among the oldest and largest producers of beams in Iran. It has two beam production lines, namely Line630 and Line 650. In this study, the mechanical properties of manufactured beams in these production lines werecompared. Based on the t-test results, the e...

fumonisins, a family of mycotoxins, are mainly toxic and carcinogenic. the present study was carried out to evaluate fumonisin b1 (fb1) effects on the production of inflammatory cytokines by gastric and colon cell lines. the study was performed on two cell lines under in vitro condition, including gastric epithelial cell line (ags) and human colon adenocarcinoma cell line (sw742). lipopolysacch...
the best method of fish breeding is the isolation of pure lines having high-producing hybrids. the decline in heterosis (dih) resulted from inbreeding, maternal effects, general combining ability (gca) and specific combining ability (sca) on reproductive traits (e.g., egg production, number of hatched egg, and hatchability of pure lines and crosses) of tiger, green, and albino barbie hybrids we...
The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...
This paper presents a software tool, called PLAT (Production Lines Analysis Tool), which computes exact stochastic solutions of models for reliable production lines. The user interface accepts the following parameters of serial production lines: the number of reliable stations (K), the service rate of each station (μi) and the buffer slots in front of each station (Bi). In the case of a transie...
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...
