The multi-objective optimization problem could be generally formulated as minimization of vector objectives subject to a number of constraints and bounds. Among the non-derivative problems, genetic algorithms have been proved to be a good solution in addressing ill-posed problem. We applied the multi-objective optimization to fuzzy controller design in order to obtain a optimal solution that is often a compromise between different objectives.

Magnesium deficit produce neuromuscular hyper-reactivity, psychic reactions, functional hypoparathyroidism, increase of K+ channels membranes permeability, while hypermagnesemia decrease Ach release from neuromuscular synapsis, with post-synaptic excitability decreasing. Using BEROCCA (Hoffman la Roche) 1 cp/day, 30 days at the teenagers with behaviour troubles and at a goup of pregnant women (trimester I-III) with paresthesia, irritability, sleeplessness, we observed an improve of clinical signs, increasing plasma Ca2+ and Mg2+.

In many medical fields the recovery of muscular activity or its improvement up to the level of the optimal parameters is required. Apart from the classical solution for rehabilitation (physical exercises) the use of electrical stimulation has become quite frequent of late. The paper presents an interface that detects the electromyographic (EMG) activity, assesses it, and generates appropriate electrical stimuli, by means of a specific type of fuzzy control system, in order to control the dynamics of the EMG.

Thus pharmacological blockade of the endogenous opioid system by mu or delta opioid receptor antagonists prevents ethanol's activation of the dopamine system and reduces ethanol consumption. The role of genetic factors in alcohol dependency is recognized.

Cytokines can act on the some membrane receptor like the neurotransmitters, and they can produce diverse biological effects. Pro-inflammatory, anti-inflammatory or haematopoetic cytokines as those in the central nervous system can be identified by immunoassay and bioassay methods.
