متن کاملA mono-sited transferrin from a representative deuterostome: the ascidian Pyura stolonifera (subphylum Urochordata).
An iron-binding protein has been found in the plasma of Pyura stolonifera. This protein has a molecular weight of about 41,000 +/- 2,000 and binds 1 mol iron/mol protein. The absorption maxima are lambda = 280 and lambda = 429 nm (E429/E280 = 0.044). Bicarbonate is bound concomitantly with high affinity and is necessary for optimal color formation at lambda = 429 nm. The protein showed a neglig...
متن کاملBaleen Hydrodynamics and Morphology of Cross-Flow Filtration in Balaenid Whale Suspension Feeding
The traditional view of mysticete feeding involves static baleen directly sieving particles from seawater using a simple, dead-end flow-through filtration mechanism. Flow tank experiments on bowhead (Balaena mysticetus) baleen indicate the long-standing model of dead-end filtration, at least in balaenid (bowhead and right) whales, is not merely simplistic but wrong. To recreate continuous intra...
متن کاملRecent introduction of the dominant tunicate, Pyura praeputialis (Urochordata, Pyuridae) to Antofagasta, Chile.
The large sessile tunicate Pyura stolonifera (Pleurogona: Stolibranchiata: Pyuridae), has been regarded as a complex taxon with disjointed distributions, including Australia (Pyura stolonifera praeputialis), South Africa (Pyura stolonifera stolonifera) and South America (Chile, Antofagasta: Pyura sp., the 'piure de Antofagasta'), and has been cited under at least five taxonomic combinations. Th...
متن کاملDesign and fabrication of an effective micromixer through passive method
Micromixer is a significant component of microfluidics particularly in lab-on-chip applications so that there has been a growing need for design and fabrication of micromixers with a shorter length and higher efficiency. Despite most of the passive micromixers that suffer from long mixing path and complicated geometry to increase the efficiency, our novel design suggests a highly efficient micr...
