in this research psedomonas fluorescens as a probiotic, sodium chloride, plant extract (terminalia catappa), malachite green and formalin as antifungal agents were used daily for 19 days on rainbow trout fertilized eggs in order to compare their survival with untreated fertilized eggs in control group. results showed that the percent of live eggs (eyed) after 19 days treatment with p. fluoresce...
1.0 overview it seems that grammar plays a crucial role in the area of second and foreign language learning and widely has been acknowledged in grammar research. in other words, teaching grammar is an issue which has attracted much attention to itself, and a lot of teachers argue about the existence of grammar in language teaching and learning. this issue will remind us a famous sentence f...
Polygalacturonase (PG) is one of the cell wall hydrolytic enzymes involving in pectin degradation. A comparison of two highly conserved duplicated PG genes, namely, Brassica campestris Male Fertility 26a (BcMF26a) and BcMF26b, revealed the different features of their expression patterns and functions. We found that these two genes were orthologous genes of At4g33440, and they originated from a ...
The effects of different cell monolayers on in vitro development of early bovine embryos derived from in vitro maturation and fertilization were examined in this study. Early embryos (four to eight cells) were randomly allocated to bovine granulosa cell (GC), oviductal cell (OC), or uterine cell (UC) monolayers in Exp. 1 and to GC, skin cell (SC; from 10-d-old chicken embryos), testicular cell ...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Plant pollens and fungal spores are massively produced in natural habitats large-scaled agricultural areas, the airborne transported biomass can be accumulated on relatively large crop surfaces. A pollen grain contains a specific chemical composition quantity quality, highly varied among plant species. So, could provide species-specific nutrient supply for initial development trap. Thus, this i...
introduction: the incidence of sperm and oocyte premature chromosome condensation (pcc) in the failed fertilized oocytes that were taken after routine in viro fertilization (ivf) and intracytoplasmic sperm injection (icsi) programs were investigated. materials and methods: in this study, 364 air-dried preparations of failed fertilized oocytes after either ivf or ocsi procedures were analyzed. t...
Allergic diseases have been increasing in industrialized countries. The environment is thought to have both direct and indirect modulatory effects on disease pathogenesis, including alterating on the allergenicity of pollens. Certain plant proteins known as pathogenesis-related proteins appear to be up-regulated by certain environmental conditions, including pollutants, and some have emerged as...
