1. Opto-electronic Properties of Nano-electronic Materials
Nanoelectronic is nanotechnology applied in the context of electronic circuits and systems. Molecular electronic, which is supposed to replace silicon electronic in the future, is an incipient branch of Nanotechnology which focusing on the organic molecules. Since recognizing and examining this family of Nanostructures needs a long time and very expensive, a

2. Glial scar-modulation as therapeutic tool in spinal cord injury in animal models
Abstract Purpose: Spinal Cord injury represents, in veterinary medicine, most of the neurological attendances and may result in permanent disability, death or euthanasia. Due to inflammation resulting from trauma, it originates the glial scar, which is a cell interaction complex system. Its function is to preserve the healthy circuits, however, it creates

3. Análise de genes envolvidos no modelo de epilepsia de lobo temporal induzido pela pilocarpina / Analysis of genes involved in the temporal lobe epilepsy induced by pilocarpine
The epilepsies affect approximately 1% of the population worldwide. Temporal lobe epilepsy (TLE) is the most frequent and commonly resistant to clinical treatment. Animal models have been widely used in order to study the mechanisms underlying TLE, especially those induced by chemical agents or electrical stimulation. It is believed that these models present

4. Learning about brain physiology and complexity from the study of the epilepsies
The brain is a complex system, which produces emergent properties such as those associated with activity-dependent plasticity in processes of learning and memory. Therefore, understanding the integrated structures and functions of the brain is well beyond the scope of either superficial or extremely reductionistic approaches. Although a combination of zoom-i

6. EVOLUTIONARY SYNTHESIS IN NANOTECHNOLOGY / SÍNTESE EVOLUCIONÁRIA EM NANOTECNOLOGIA
The first Nanotechnology concepts were introduced by the American physicist Richard Feynman in 1959, in his famous lecture entitled There´s plenty of room at the bottom. Computational Intelligence has been successfully used in various areas in the academic and industrial worlds. This work investigates the potential of Genetic Algorithms in the optimization

7. Gap junction modulation by extracellular signaling molecules: the thymus model
Gap junctions are intercellular channels which connect adjacent cells and allow direct exchange of molecules of low molecular weight between them. Such a communication has been described as fundamental in many systems due to its importance in coordination, proliferation and differentiation. Recently, it has been shown that gap junctional intercellular commun

8. A caracterização de laser de diodo para espectroscopia de alta resolução
In the last decade the diode lasers became the most important in economics. The use of diode lasers in Physics and Technology has expanded rapidly. This has occurred because their low cost, reliability , durability and possibility of integrating with electronic components to form integrated optoeletronic circuits. The development of novel techniques to contr

9. Nonlinear protein degradation and the function of genetic circuits
The functions of most genetic circuits require a sufficient degree of cooperativity in the circuit components. Although mechanisms of cooperativity have been studied most extensively in the context of transcriptional initiation control, cooperativity from other processes involved in the operation of the circuits can also play important roles. In this work, w

10. Increase in Syntaxin 1B mRNA in Hippocampal and Cortical Circuits During Spatial Learning Reflects a Mechanism of Trans-synaptic Plasticity Involved in Establishing a Memory Trace
It has long been proposed that the cellular and molecular mechanisms responsible for LTP may well involve the mechanisms that lead to the type of synaptic modification that occurs during learning. However, it is also known that a single memory trace is encoded in spatially distributed networks; implying that alterations of synaptic strength occur at multiple

11. Muscarinic acetylcholine receptor expression in memory circuits: Implications for treatment of Alzheimer disease
Cholinergic transmission at muscarinic acetylcholine receptors (mAChR) has been implicated in higher brain functions such as learning and memory, and loss of synapses may contribute to the symptoms of Alzheimer disease. A heterogeneous family of five genetically distinct mAChR subtypes differentially modulate a variety of intracellular signaling systems

12. Circuits and programmable self-assembling DNA structures
Self-assembly is beginning to be seen as a practical vehicle for computation. We investigate how basic ideas on tiling can be applied to the assembly and evaluation of circuits. We suggest that these procedures can be realized on the molecular scale through the medium of self-assembled DNA tiles. One layer of self-assembled DNA tiles will be used as the prog
