Polymeric alkylpyridinium salts (poly-APS) isolated from the marine sponge Reniera sarai act as antifouling and anticholinesterase agents. They also show moderate haemolytic and cytotoxic activities against different cell lines. The haemolytic activity of poly-APS is due to their detergent-like structure and behaviour in aqueous solutions. In this work, the lytic activity of poly-APS against fr...
Magnetic tunnel junction nanopillar with interfacial perpendicular magnetic anisotropy (PMA-MTJ) becomes a promising candidate to build up spin transfer torque magnetic random access memory (STT-MRAM) for the next generation of non-volatile memory as it features low spin transfer switching current, fast speed, high scalability, and easy integration into conventional complementary metal oxide se...
The carbon metabolism of two marine sponges, Haliclona oculata and Dysidea avara, has been studied using a 13C isotope pulse-chase approach. The sponges were fed 13C-labeled diatoms (Skeletonema costatum) for 8 h and they took up between 75 and 85%. At different times, sponges were sampled for total 13C enrichment, and fatty acid (FA) composition and 13C enrichment. Algal biomarkers present in ...
نمونه‌های اسفنج با گشت زنی در منطقه بین جزر ومدی جزیره هنگام در زمان بیشینه جزر از ایستگاه آب شیرین کن در شمال غربی جزیره به مختصات جغرافیایی N˝55΄40˚26 و E˝17΄52˚55 در مرداد ماه سال 1388 جمع‌آوری گردید. نمونه‌برداری در یک نوبت و بدون استفاده از تجهیزات خاص انجام گرفت. برای شناسایی نمونه‌های اسفنج از روش هضم اسیدی و برش‌گیری ساختار اسکلتی استفاده گردید. همه نمونه‌های اسفنج شناسایی شده، از رده ...

Bacteriocins are attracting increased attention as an alternative to classic antibiotics in the fight against infectious disease and multidrug resistant pathogens. Bacillus subtilis strain MMA7 isolated from the marine sponge Haliclona simulans displays a broad spectrum antimicrobial activity, which includes Gram-positive and Gram-negative pathogens, as well as several pathogenic Candida specie...
Sponge-microbe symbioses underpin the ecological success of sponges in many aquatic benthic ecosystems worldwide. These are often described as mutually beneficial, but identifying positive symbiotic interactions and quantifying contribution partners to physiological processes is challenging. For example, our understanding relative sponge cells their microbial symbionts uptake exchange dissolved...
