Invertebrates were traditionally thought to rely on the innate arm of the defense system to fight against pathogens [1,2], and adaptivity or memory of immune responses were previously considered the hallmark of a highly evolved immune system, only present in vertebrates [3]. However, there are now evidences indicating that invertebrates have immunological specificity and memory of a kind that i...

Because of limitations of production of unicellular green algae (especially in large volumes), this study aimed to culture Artemia using three sources of cheap agricultural by-products that were coupled with small amounts of unicellular algae Dunaliella salina. The results of growth and survival, biomass production, Individual wet weight, wet and ash percent, FCR and SGR and nutritional value o...

BACKGROUND Artemia (brine shrimp) is used as feed for fish fry and shrimp in aquaculture. Two employees in a Norwegian aquaculture research farm reported having chest symptoms when working in an Artemia hatch room. AIMS To determine the presence and prevalence of Artemia sensitization at the farm and the extent of any Artemia-related respiratory and hand skin symptoms and to identify the alle...

The article presents the analysis of biological parameters parthenogenetics Artemia crustaceans hypergaline reservoirs Kazakhstan. In lakes under study there are shown changes total crustacean biomass decreasing from high-productive to low-productive. Most with in Kazakhstan characterized by presence parthenogenetic populations absence or extremely small males. aggregation males significant num...

The fate of parthenogenetic cells was investigated during development of fetal and early postnatal chimeras. On day 13 of embryonic development, considerable contribution of parthenogenetic cells was observed in all tissues of chimeric embryos, although selection against parthenogenetic cells seemed to start before day 13. Between days 13 and 15 of development, parthenogenetic cells came under ...

We tested whether Artemia abd-A could repress limbs in Drosophila embryos, and found that although abd-A transcripts were produced, ABD-A protein was not. Similarly, developing Artemia epidermal cells showed expression of abd-A transcripts without accumulation of ABD-A protein. This finding in Artemia reveals a new variation in Hox gene function that is associated with morphological evolution. ...
