How red blood cells behave in tiny tubes

How old are dense red blood Cells? The dog's tale.

How do red blood cells know when to die ?

Human red blood cells (RBCs) are normally phagocytized by macrophages of splenic and hepatic sinusoids at 120 days of age. The destruction of RBCs is ultimately controlled by antagonist effects of phosphatidylserine (PS) and CD47 on the phagocytic activity of macrophages. In this work, we introduce a conceptual model that explains RBC lifespan as a consequence of the dynamics of these molecules...

How Tropicbirds Behave at Sea

28 fledged per nest in the native habitat, but only 1.0 per nest in the wheatgrass, Lloyd and Martin reported in 2005 (Condor 107:363–374). These significantly different success rates resulted primarily from greater nest predation in the wheatgrass. The odds of a nest surviving a given day were 17 percent higher in the native-prairie patches than in the wheatgrass plots. Nestlings in the native...

Optimizing Red Blood Cells Consumption Using Markov Decision Process

In healthcare systems, one of the important actions is related to perishable products such as red blood cells (RBCs) units that its consumption management in different periods can contribute greatly to the optimality of the system. In this paper, main goal is to enhance the ability of medical community to organize the RBCs units’ consumption in way to deliver the unit order timely with a focus ...
