Revisiting Epithelial Carcinogenesis por Méndez López, Luis Fernando

“…This paper presents a hypothesis for the origin of carcinomas in which cellular aging and inflammation enable the recovery of cellular plasticity, which may ultimately result in cancer. The hypothesis describes carcinogenesis as the result of the dedifferentiation undergone by epithelial cells in hyperplasia due to replicative senescence towards a mesenchymal cell state with potentially cancerous behavior. …”

The use of immune-stimulants in fish and shellfish feeds por Raa, Jan

“…The most promising group of immune-stimulants are the b-1,3/1,6-glucans, because theyhave a well-defined chemical structure and mode of action on the immune system, described in a greatnumber of scientific papers. In addition, b-1,3/1,6-glucans are non-toxic universal “alarm signals”which activate the immune system by the same basic mechanism in all animal groups, from the simplestinvertebrates to man. b-1,3/1,6-Glucans are active not only when injected, but also when administered inthe feed, or on mucosal surfaces. …”
