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...

Lantana camara Linn is a family of Verbenaceae which grows wild and widespread in various both tropical sub-tropical countries. Isolation essential oil the L. leaves extracted by hydrodistillation were analyzed Gas Chromatography-Mass Spectrometry (GC-MS). The results GC-MS analysis show isocaryophyllene (14.39%), ρ-cymene (8.17 %), β-cubebene (7.8 α-pinene (7.64 β-elemene (5.51 %) as main comp...

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...

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...

This is the first study on phylogenetic relationships in the genus Artemia Leach, 1819 using the pattern and sequence of secondary structures of internal transcribed spacer 1 (ITS1). Significant intraspecific variation in the secondary structure of ITS1 rRNA was found in Artemia tibetiana. In the phylogenetic tree based on joined primary and secondary structure sequences, Artemia urmiana and pa...
