Scopo di questo saggio è la discussione di alcune proprietà dei numeri primi che hanno trovato importantissime applicazioni pratiche con l’avvento della crittografia a chiave pubblica negli anni ’70 e con la diffusione di Internet e del commercio elettronico di questi ultimi anni. Ci occuperemo di alc...

Is the neutrophil a ‘prima donna’ in the procoagulant process during sepsis?

Activation of the coagulation system is a fundamental host defense mechanism. Microorganisms that have invaded the body are trapped and disposed of in clots. Monocytes/macrophages are widely accepted as the main players in the procoagulant process; however, recent evidence suggests that neutrophils also play important roles. Tissue factor, which initiates the extrinsic coagulation cascade, is r...

Although it is widely believed that mental simulations enhance future behavior, virtually nothing is known about how memory for these simulations changes over time or whether simulations of emotional experiences are especially well remembered.

Association of DNA methylation with imprinting, embryonic development and human diseases is discussed. Furthermore, besides considering changes in DNA methylation as mechanisms of disease, the role of epigenetics in general and DNA methylation in particular in tr...
