1. Difference of brain-derived neurotrophic factor expression and pyramid cell count during mastication of food with varying hardness
Abstract Previous studies suggested that mastication activity can affect learning and memory function. However, most were focused on mastication impaired models by providing long-term soft diet. The effects of chewing food with various hardness, especially during the growth period, remain unknown. Objective: To analyze the difference of hippocampus function

2. Desenvolvimento e estudo de materiais termoluminescentes baseados em óxido de alumínio para aplicação em dosimetria / Development and study of thermoluminescent materials based on aluminum oxide for dosimetry application
The aluminum oxide was one of the former compounds investigated with a view to detecting and measuring radiation by means of the thermoluminescence (TL). Commonly referred to as \"alumina\", aluminum oxide has interesting features for the development of materials for dosimetry. Its effective atomic number has an intermediate value between the bone and soft t

3. Formas farmacêuticas monolíticas como sistemas multiparticulados / Monolithic dosage form as a multiple unit particulate system
Sistemas multiparticulados revestidos, tais como grânulos (pellets), têm ganhado crescente atenção nos últimos anos. Eles apresentam melhorias na biodisponibilidade e na segurança da liberação do fármaco. A possível utilização destes sistemas como constituintes de cápsulas e comprimidos traz, como principal vantagem, a divisibilidade da forma fa

4. Síntese, sinterização e caracterização de ferritas à base de Ni-Zn
Were synthesized different ferrites NixZn1-xFe2O4 (0,4 ≤ x ≤ 0,6) compositions by using citrate precursor method. Initially, the precursors citrates of iron, nickel and zinc were mixed and homogenized. The stoichiometric compositions were calcined at 350C without atmosphere control and the calcined powders were pressed in pellets and toroids. The

6. Synthesis and characterization of bismuth zinc niobate pyrochlore nanopowders
Bismuth zinc niobate pyrochlores Bi1.5ZnNb1.5O7 (alpha-BZN), and Bi2(Zn1/3Nb2/3)2O 7 (beta-BZN) have been synthesized by chemical method based on the polymeric precursors. The pyrochlore phase was investigated by differential scanning calorimetry, infrared spectroscopy, and X ray diffraction. Powder and sintered pellets morphology was examined by scanning el

7. Forecasting disruptions Instabilities by artificial neural networks / Previsão das Instabilidades de Disruptura através de Redes Neurais Artificiais
Two-layer feedforward neural network has been used in this work to forecast the disruptive instabilities that occur in the TEXT tokamak plasma discharges. For this task, soft X-ray experimental signals were used with very promising results. It was verified that a neural net with an architecture of the type m:2m:m:1, where m is the embedding dimension of the

8. The possible relation between mastication and parotid secretion in the rabbit.
Salivary flow has been recorded from conscious rabbits during 1 min periods whilst continuously chewing standard laboratory dry pellets or pieces of carrot and, in some animals, a mash of pellets with water. Flow was measured using contact drop recorders or a continuous flow recorder via Polythene tubes permanently inserted into one or both parotid ducts. La

9. Colonic motility and transit of digesta during hard and soft faeces formation in rabbits.
Rabbits produce hard and soft faeces in a circadian rhythm. This study was undertaken in order to examine the motor function of the colon in relation to the formation of these two types of faeces. Colonic motility was measured in unanaesthetized rabbits using strain-gauge transducers and simultaneous radiography. Three types of contractions were found in the

10. OP-1 Augments Glucocorticoid-inhibited Fracture Healing in a Rat Fracture Model
Glucocorticoids inhibit bone remodeling and fracture healing. We sought to determine whether osteogenic protein 1 (OP-1) can overcome this inhibition in a closed fracture model in the rat. Time-released prednisolone or placebo pellets were implanted subcutaneously; closed femoral fractures were created 2 weeks later in rats. Fractures received sham, OP-1 an

11. Expression of Q227L-Gαs in MCF-7 human breast cancer cells inhibits tumorigenesis
The effects of expression of mutant (Q227L)-activated Gαs and elevation of cAMP on mitogen-activating protein kinase (MAPK) activity and the transformed phenotype were studied in the MCF-7 human mammary epithelial cell line. Elevation of cAMP partially inhibited the epidermal growth factor-stimulated DNA synthesis and the intrinsic MAPK (ERK-1 and ERK-2) of
