Developing an optimal diet for rearing endangered white-clawed crayfish Austropotamobius pallipes is important captive breeding success prior to wild release. Four ex situ , 40-day experiments assessed survival and growth of fed different treatment diets. Two (A B) were undertaken with hatchlings, determine if live food was essential dietary component during the first few weeks after hatching. ...

Maculalactone A (1) constitutes a promising antifouling agent, inhibiting the formation of biofilms in marine and freshwater systems. In this study, we developed a new route, based on a late-stage formation of the butenolide core, leading to the total synthesis of maculalactone A (three steps, overall yield of 45%) and delivering material on a gram scale. In addition, analogues of the title com...

This study aimed to evaluate the effects of using Artemia franciscana enriched with cod liver oil and vitamins C and E on the growth, survival and stress resistance of juvenile Sepia pharaonis (Pharaoh cuttlefish). Twenty-five days after hatching, the larvae of S. pharaonis were transferred into culture tanks with an average length of 15.97±0.15 mm and average body weight of 3.53±0.03 g, in ele...

Increasing marine microplastic pollution has detrimentally impacted organismal physiology and ecosystem functioning. While previous studies document negative effects of microplastics on coral reef animals, the potential responses organisms such as large benthic foraminifera (LBF) are largely unknown. Here, we impact heterotrophic feeding behavior LBF. Specimens Amphistegina gibbosa were incubat...

different opinions exit in histological typing of bone cysts. epidermoid cysts are very rare as the small numbers of published cases indicate. they arises following preceding trauma exclusively in distal phalanges and skull. the roentgenogram shows a round osteolytic resion with no trabecular pattern. we observed 2 cases of epidermoid cyst of finger in imam khomeini hospital central path depart...

Feeding farmed Artemia with yeast heat shock proteins is a novel way to protect them from stress conditions during the culture.  In this study, the effect of feeding with stressed new identified Saccharomyces cerevisiae strain YG3-1 yeasts (containing induced heat shock proteins) on the survival of Artemia in stress conditions, was evaluated. For this purpose, heat shock proteins 82 (Hsps 82) o...

in this study the optimal amount of enriching artemia franciscana with a synbiotic combination of pediococcus acidilactici and fructooligosaccharide (fos( was investigated. the experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics p. acidilactici (1×109, 1×108 and 1× 107 cfu per l) and multi-level enriched prebiotic fos (1, 2 and 5) g per l of solu...
