| life cycle characteristics of six artemia populations from iran. | the present study was conducted to achieve the life cycle characteristics of six artemia populations (one bisexual and five parthenogenetic) from iran. the cysts of parthenogenetic strains were collected from maharlu, incheh, varmal and qom salt lakes and lagoons at the periphery of lake urmia. cysts of the bisexual artemia urmiana were collected from the lake urmia. all cysts strains were hatched using the standard procedures and the nauplii from all populations were reared at 80 g l(-1) at lab ... | 2008 | 18814646 |
| effects of yeast probiotic (thepax) enrichment on biochemical parameters of a. urmiana nauplii. | nauplii artemia urmiana was enriched with thepax--a commercial product containing yeast cells of saccharomyces cerevisiae. the thepax-induced changes in biochemical parameters such as crude protein, fat, fiber, ash and energy were determined in the nauplii enriched at different times (6, 12 and 18 h) after hatching. to identify these changes, each group of nauplii (6, 12 and 18 h post-hatching) was enriched with 10(7) colony forming units (cfu ml(-1)) for a 24 h period. enrichment with thepax in ... | 2008 | 18817141 |
| use of probiotic bacillus spp. in rotifer (brachionus plicatilis) and artemia (artemia urmiana) enrichment: effects on growth and survival of pacific white shrimp, litopenaeus vannamei, larvae. | this study was to evaluate the effect of a preparation of bacillus probiotic (bacillus licheniformis and b. subtilis, 1:1) on growth and survival rate of pacific white shrimp, litopenaeus vannamei larvae. the larvae were fed on artemia urmiana nauplii and brachionus plicatilis enriched with the probiotic preparation at 1 × 10(6) cfu ml(-1) rate. the experimental setup was completely randomized design comprised of six treatments, namely solo artemia nauplii (a) or rotifer (r), artemia nauplii and ... | 2015 | 25721675 |
| artemin protects cells and proteins against oxidative and salt stress. | artemin is an abundant thermostable protein in artemia encysted embryos under environmental stresses. it is confirmed that high regulatory expression of artemin is relevant to stress resistance in this crustacean. here, the protective role of artemin from artemia urmiana has been investigated on survival of bacterial cells under salt and oxidative shocks. also, for continuous monitoring of the effect of artemin in prevention of proteins aggregation/inactivation, co-expression of artemin and luci ... | 2017 | 27894826 |
| real-time monitoring of artemin in vivo chaperone activity using luciferase as an intracellular reporter. | artemin is an abundant thermostable protein in artemia encysted embryos and considered as a stress protein, as its highly regulated expression is associated with stress resistance. artemin cdna was previously isolated and cloned from artemia urmiana and artemin was found as an efficient molecular chaperone in vitro. here, co-transformation of e. coli was performed with two expression vectors containing artemin and firefly luciferase for in vivo studies. the time-course of luciferase inactivation ... | 2016 | 27693039 |
| effect of artemin on structural transition of β-lactoglobulin. | encysted embryos of artemia are exceptionally resistant to severe environmental stress. this resistance is thought to depend in part on the existence of a protein termed artemin. there is only little information about the function of artemin. it has been reported artemin is a thermostable protein with rna-binding ability. in addition, it reduces the extent of aggregation significantly and enhances the efficiency of refolding and activity recovery of carbonic anhydrase and horseradish peroxidase. ... | 2013 | 23291197 |
| physiological characteristics and stress resistance of great sturgeon (huso huso) juveniles fed with vitamins c, e, and hufa-enriched artemia urmiana nauplii. | this study was carried out to examine the effect of artemia urmiana nauplii enriched with hufa, and vitamins c and e on stress tolerance, hematocrit, and biochemical parameters of great sturgeon, huso huso juveniles. cod liver oil (epa 18% and dha 12%), ascorbyl-6-palmitate and alpha-tocopherol acetate were used as lipid, and vitamin c and e sources, respectively. beluga juveniles at the stage of first feeding (69.7 +/- 5.9 mg body weight) were randomly divided into five treatments and three tan ... | 2010 | 19459059 |
| mitochondrial genome sequences of artemia tibetiana and artemia urmiana: assessing molecular changes for high plateau adaptation. | brine shrimps, artemia (crustacea, anostraca), inhabit hypersaline environments and have a broad geographical distribution from sea level to high plateaus. artemia therefore possess significant genetic diversity, which gives them their outstanding adaptability. to understand this remarkable plasticity, we sequenced the mitochondrial genomes of two artemia tibetiana isolates from the tibetan plateau in china and one artemia urmiana isolate from lake urmia in iran and compared them with the genome ... | 2013 | 23633076 |
