In this study the composition of the stevia extracts obtained in different stages of the process in a pilot unit of extraction and purification was monitored by high performance chromatography (HPLC) analyzes. The permeate from the nanofiltration ste

Samples of commercial Stevia Extracts from different countries (USA, China, Japan, France, Brazil and Paraguay) were analyzed quantitatively and qualitatively by HPLC and UHPLC-MS-MS-QTOF. Extract 03 (Japan) presented the lowest value of total glycos

Stevia leaves (Stevia rebaudiana Bert.), that present high-intensity natural sweeteners (steviol glycosides), also has a series of secondary metabolites for which have been reported biological effects such as antioxidants, antihyperglycemic and insul

Some years ago a cellular automata model was proposed to describe the evolution of the immune repertoire of B cells and antibodies based on Jerne's immune network theory and shape-space formalism. Here we investigate if the networks generated by this

In this paper we review the trajectory of a model proposed by Stauffer and Weisbuch in 1992 to describe the evolution of the immune repertoire and present new results about its dynamical behavior. Ten years later this model, which is based on the ide

We use a cellular automata model to study the evolution of HIV infection and the onset of AIDS. The model takes into account the global features of the immune response to any pathogen, the fast mutation rate of the HIV and a fair amount of spatial lo

The immune system can be thought as a complex network of different interacting elements. A cellular automaton, defined in shape-space, was recently shown to exhibit self-regulation and complex behavior and is, therefore, a good candidate to model the

The dynamics of human immunodeficiency virus infection under antiretroviral therapy is investigated using a cellular automata model where the effectiveness of each drug is self-adjusted by the concentration of CD4 + T infected cells present at each t

In this paper, we study the dynamics of a multi-connected network which has been used recently to simulate the evolution of the immune repertoire. In particular, we used this model to reproduce experimental results about immunization and aging perfor

Cellular automata are very simple systems that can exhibit complex dynamics on its time evolution. Over the last decade there have been many applications of cellular automata to modeling of biological systems. Those applications have been stimulated
