We compare the nutrient-dependent photosynthetic efficiencies of the chlorophyte, Dunaliella tertiolecta, with those of the marine diatom, Thalassiosira weissflogii. Despite considerable evolutionary and physiological differences, these two species appear to use nearly identical growth strategies under a wide range of nutrient limitation. Using a variety of physiological measurements, we find ...

Whole blood or RBC transfusions are highly significant, clinically, for blood replacement therapies in traumatic injuries, pre-surgical conditions and anemias. However, natural RBC-based products suffer from limited shelf-life due to pathological contamination, and also present risks of refractoriness, graft-versus-host disease, immunosuppression and acute lung injury. These issues can be only ...

The pathogenesis of systemic lupus erythematosus (SLE) entails a complex interaction between the different arms of the immune system. While autoantibodies production and immune complex deposition are cornered as hallmark features of SLE, there is growing evidence to propose the pathogenic role of cytokines in this disease. Examples of these ...

The epidemiology of vector transmitted plant diseases is highly influenced by dispersal and the host-plant range of the vector. Widening the vector's host range may increase transmission potential, whereas specialization may induce specific disease cycles. The process leading to a vector's host shift and its epidemiological outcome is therefore embedded ...
