Synergistic interaction between 4-allyl-1-hydroxy-2-methoxybenzene (eugenol) and diclofenac: An isobolograpic analysis in Wistar rats.

Clinical and preclinical research that contributes pain palliation has suggested that drugs favor the expected effects and minimize the adverse effects. Among the most widely used strategies is the combination of analgesic drugs among those in the same group, with those in another group of analgesics or with co-adjuvants (nonanalgesic drugs or elements of traditional medicine). This work aims to evaluate the interaction between eugenol (EUG) and diclofenac (DFC) on nociception in the presence of a noxious stimulus through the formalin test and isobolographic analysis.

Influence of Background Noise Produced in University Facilities on the Brain Waves Associated With Attention of Students and Employees.

As a consequence of noise exposure, lack of attention badly affects directly the academic and work performance. The study of the brain and the waves that it produces is the most objective way to evaluate this process. Attentional improvement is associated with increases of the amplitude in both beta and theta bands.

Forced synchronization of autonomous dynamical Boolean networks.

We present the design of an autonomous time-delay Boolean network realized with readily available electronic components. Through simulations and experiments that account for the detailed nonlinear response of each circuit element, we demonstrate that a network with five Boolean nodes displays complex behavior. Furthermore, we show that the dynamics of two identical networks display near-instantaneous synchronization to a periodic state when forced by a common periodic Boolean signal.

[Pioglitazone hydrochloride a instrumental analytical perspective by Raman spectroscopy and HPLC].

Introduction: The thiazolidinediones (pioglitazone) increases the action of insulin and produces the glycemic control in the patients with type 2 diabetes mellitus. Also, the pharmacological effect may be affected by the purity and pioglitazone plasma concentration. Therefore, the instrumental techniques offer a tool for characterization, identification and/or quantification of the pioglitazone; Raman spectroscopy offers several advantages due to its easy application methodology and structural analysis and the HPLC technique is the gold standard vs.

Forced synchronization of a self-sustained chaotic oscillator.

This work presents a forced synchronization phenomenon like the asymptotic correlated behavior between chaotic oscillators forced by an external signal. Different kinds of forced synchronization are presented and given a theoretical justification explaining why it is possible to find some of them. Numerical results are presented for different cases such as antisymmetric, lag, phase, and identical forced synchronization.
