To support the use of marine demosponges for collagen production in integrated culture settings, we investigated a low–cost, easily applicable and sustainable method Chondrosia reniformis Nardo, 1847 ( Demospongiae , Chondrosiida Chondrosiidae ). Novel methods were tested to this collagen-rich demosponge three consecutive trials, during which recovery, survival growth rates explants monitored c...

Background: Poorly educated people in some parts of Iran use burned mantles as a wound healing medicine. Materials and Methods: To perform surface area measurement, twenty rats were divided randomly into two groups of 10 animals each. The first group received topical burned radioactive lantern mantle powder on the first to third days after making excision wounds. The second group rece...

Abstract: For increasing the efficiency of omega-3 production, effect span-85 surfactant as a hydrophobic agent (0, 1, 2, 3 and 4 wt%) on formation porous structure in sub-layer PVDF membrane was studied. Also, cross-sectional morphology membranes analyzed using scanning electron microscopy (SEM) surface property evaluated contact angle test. The capacity to concentrate examined by filtration l...
