background: as we all know, sperm has the capacity to take up foreign dna, therefore, sperm mediated gen transfer can be an inexpensive and simple method in animal transgenesis in various species. however, there is not sufficient evidence of dna uptake by ovine spermatozoa. objectives: the purpose of the present study was to examine the uptake of human lysozyme gene contained plasmid (pegfp-ire...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...

to study the response of pinto-bean yield and yield components in intercropping with maize and naked-pumpkin under weed competition, two similar experiments were conducted in rasht and roudsar separately each in a randomized complete block design with 3 replications on factorial arrangements experiment in 2013. the treatments of first factor consisted of  pinto bean (100 and 75%) sole cropping,...

the aim of this research was to evaluate the effect of one session of exhaustive exercise with low intensity (55-65% vo2max), moderate intensity (65-75% vo2max) and high intensity (75-85% vo2max) on adiponectin in active women. for this purpose, 30 healthy women (mean age 21.6 years, weigh 59.7+3.35 kg, vo2max 39.1+0.58 ml/kg/min, no history of cardiovascular diseases and diabetes) were selecte...

earthworms are an important part of food chain in soil ecosystem. in polluted soils, heavy metals are consumed by earthworms and transferred to other organisms through food chain, resulting in many adverse health impacts. due to the benefits of earthworms for soil fertility, it is important to assess the effects of soil pollution on population, biomass and functions of earthworms. to determine ...

in order to determine the lipids and lipoproteins profiles in iranian khouzestanian arab horses, blood samples were collected from the jugular vein of 77 horses(47 female, 30 male) from different age groups(< 6, 7-12, 12-36, 37-60, 61- 69 and > 96 months). serum cholesterol and triglyceride were measured by enzymatic methods and lipoproteins by precipitation methods. the results were analyzed b...

to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...

introduction today, with the increasing population and the need for strategic and industrial crops the farmers are simulated to grow these kinds of crops. thus, this subject has now been caused the inappropriate use of land and natural resources. on the other hand, the natural environment resources have limited the ability to use its resources and the climate change intensifies this limit abili...
