1. Genetic basis of triatomine behavior: lessons from available insect genomes
Triatomines have been important model organisms for behavioural research. Diverse reports about triatomine host search, pheromone communication in the sexual, shelter and alarm contexts, daily cycles of activity, refuge choice and behavioural plasticity have been published in the last two decades. In recent times, a variety of molecular genetics techniques h

2. Bases cognitivas da expectativa temporal. / The cognitive basis of temporal expectations.
The ability to anticipate future events is essential for behavior. On the present work, we investigated how different forms of temporal expectations can modulate stimuli processing. In four psychophysical experiments (two of them with EEG) we studied how voluntary action and temporal attention can influence processing at different stages. Our results suggest

3. TMEM16 proteins: the long awaited calcium-activated chloride channels?
Currents mediated by calcium-activated chloride channels (CaCCs), observed for the first time in Xenopus oocytes, have been recorded in many cells and tissues ranging from different types of neurons to epithelial and muscle cells. CaCCs play a role in the regulation of excitability in neurons including sensory receptors. In addition, they are crucial mediato

4. Análise dos eventos tônicos e fásicos do sono dessincronizado em ratos Wistar com lesão medular contusa / Análise dos eventos tônicos e fásicos do sono dessincronizado em ratos Wistar com lesão medular contusa
After a spinal cord injury (SCI), structural reorganization occurs locally and at multiple levels of the central nervous system (CNS). Compromising of sensory motor functions and significant alterations of other neural functions are normally related after a SCI. The circardians rhythms, specially the sleep-wake cycle are frequently affected after a trauma or

5. Uso da ropivacaína ou levobupivacaína na anestesia epidural toraco-lombar em cães
Based on current progress of the anesthetic techniques, it is necessary to experiment with new local anesthetics. Ropivacaine and levobupivacaine are recent formulations of long duration, the amide group, which have lower toxicity that bupivacaine. The thoracic epidural anesthesia is still little explored in Veterinary Medicine today. The purpose of this stu

6. Doctrine and Method in Forensic Medicine. An Epistemological Essay on a Bio-Psycho-Social Science / Da doutrina e do método em medicina legal. Ensaio epistemológico sobre uma ciência bio-psico-social
This essay begins with an overview of a bibliographic research on Forensic Medicine, from its early onset with Ambroise Paré, in 1532, up to the present. This research played an important role on the planning of this thesis (it is important to emphasize that the proper concept of Forensic Medicine, however, appears only in 1621 with Paolo Zacchia,-Quaestion

7. CaracterizaÃÃo fisica, fisico-quÃmica e enzimÃtica de frutos de seis cultivares de coqueiro anÃo em diferentes estadios de desenvolvimento / Phisical phisic-chemical, and enzimatic characterization of fruits of six dwarf coconut cultivars at different stages of development
This study aimed at characterizing in fruit and physico-chemical, and sensory enzyme in the coconut water the of six dwarf coconut cultivars at seven stages of development. The studied cultivars were: Green dwarf from Jequi (GDJ), yellow dwarf from Gramame (YDG), yellow dwarf from Malaysia (YDM), Red dwarf from Cameroon (YDC), Red dwarf from Malaysia (RDM),

8. Uso de película comestível, cloreto de cálcio e ácido ascórbico para a conservação do melão Amarelominimamente processado / Application of edible coating, calcium chloride and ascorbic acid for conservation of minimally processed melon
This work aims to evaluate the effect of the use of edible film, ascorbic acid and calcium chloride on the conservation of minimally processed melon. In order to obtain a convenient product, the microbiological aspects have been studied in order to evaluate the effect of the treatments on the respiratory rate and ethylene production of melons during the refr

9. Efeitos da estimulação elétrica do córtex motor na modulação da dor: análise comportamental e eletrofisiológica em ratos / Effects of electrical stimulation of motor cortex on pain modulation: behavior and electrophysiological study in rats.
Background. The motor function has been associated to sensory and pain attenuation, before during and shortly after the muscle activity. How ever the anatomical and functional basis of this phenomenon is not yet defined. The present study was designed to set an animal model and investigate the effect of subthreshold electrical stimulation of motor cortex (MC

10. Laranja 'Pêra' (Citrus sinensis L. Osbeck) minimamente processada: efeito de cloreto de cálcio e película de alginato de sódio na fisiologia e conservação / Minimally processed 'Pera' Orange (Citrus sinensis L. Osbeck): effect of calcium chloride and sodium alginate film on physiology and conservation
Changes in the profile of the consumer interested in healthier nutrition, associated with the practicality and convenience, have led to a new branch of food technology: minimal processing. In citrus, this processing will contribute to increased consumption of the fruit in natura, enabling the product to have added value and giving the consumer a new option.

12. Effects of maturity stage and temperature management on postharvest physiology and quality of red strawberry guava. / Efeitos do estádio de maturação e do manejo da temperatura sobre a fisiologia e qualidade pós-colheita de araçá-vermelho.
Red strawberry guava (Psidium cattleianum Sabine) has a high potential for in natura fruit commercialization. However, this requires the characterization of fruit postharvest physiology to improve its storage potential and to preserve its physical and chemical attributes. This research was carried out to study the effects of fruit maturity at harvest and sto
