The term stress was introduced into the biomedical field by Hans Selye (1936) in reference to
a General Adaptation Syndrome which would consist of all non-specific systemic reactions
that occur during an intense and chronic exposure to a stressor (e.g., pressure at work and
poor diet). This syndrome would be different from the specific adaptive reactions (such as
muscle hypertrophy caused by exercise performed on a regular basis) and immune
responses (Selye, 1936).

New approaches to tailor-made cellulose/starch/lignin-synthetic polymer graft copolymers with precise control over molecular weight, degree of substitution, backbone-graft linkage, and the overall grafting process are being studied. Cross-linked graft copolymers with exactly defined polymer chain segments between crosslink points have been prepared. The graft copolymers exhibit a two-phase morphology and can function effectively as compatibilizers/interfacial agents to alloy cellulosic and lignocellulosic materials with synthetic polymers.
Brain morphology is in constant change from the very beginning of the neurodevelopment in human beings. The characterization of the brain morphology and its biological implications on a specific subject is a complex task which requires efficient computational approaches. Radiology has traditionally assessed the main brain changes in different alterations from a macroscopic point of view, thus, not considering subtle changes as a results of neuronal plasticity.
