Empatia: ferramenta pró-social explorada num grupo terapêutico

Introdução: A empatia é um conceito multi- dimensional que engloba a capacidade de in- ferir um estado emocional e responder a emo- ções vivenciadas pelo outro, podendo ser assim categorizada em empatia cognitiva e emocional. É uma capacidade que se desenvolve pre- cocemente através, sobretudo, da interação com as figuras parentais. Não é exclusiva dos seres humanos e tem sido conservada evolutivamente, c...

Análise comparativa da postura ortostática entre mulheres fisicamente activas e...

Foi objectivo deste trabalho comparar a postura ortostática entre mulheres fisicamente activas e sedentárias. Foram estudados 60 sujeitos do sexo feminino, saudáveis e não grávidas. Trinta mulheres incluíram o grupo das fisicamente activas (GFA) e outras trinta no grupo das sedentárias (GS). Os sujeitos foram fotografados nos planos sagital direito e esquerdo, frontal anterior e posterior na posição ortostática...

Kinetics of vinyl acetate emulsion polymerization in a pulsed tubular reactor: ...

A new reactor, the pulsed sieve plate column (PSPC), was developed to perform continuous emulsion polymerization reactions. This reactor combines the enhanced flexibility of tubular reactors with the mixing behavior provided by sieved plates and by the introduction of pulses that is important to prevent emulsion destabilization. The main objective of this work is to study the kinetics of vinyl acetate (VA) emul...

ZapA, a possible virulence factor from Proteus mirabilis exhibits broad proteas...

The opportunistic bacterium Proteus mirabilis secretes a metalloprotease, ZapA, considered to be one of its virulence factors due to its IgA-degrading activity. However, the substrate specificity of this enzyme has not yet been fully characterized. In the present study we used fluorescent peptides derived from bioactive peptides and the oxidized ß-chain of insulin to determine the enzyme specificity. The bradyk...

Development of an operational substrate for ZapA, a metalloprotease secreted by...

The protease ZapA, secreted by Proteus mirabilis, has been considered to be a virulence factor of this opportunistic bacterium. The control of its expression requires the use of an appropriate methodology, which until now has not been developed. The present study focused on the replacement of azocasein with fluorogenic substrates, and on the definition of enzyme specificity. Eight fluorogenic substrates were te...

ALARM PHEROMONES AND THE INFLUENCE OF PUPAL ODOR ON THE AGGRESSIVENESS OF Polyb...

Field bioassays were used to demonstrate that aggressive behavior of Polybia paulista (Ihering) workers is elicited by alarm pheromones present in the venom reservoirs of nest defenders and that the brood care pheromone (pupal odor) produced by the young inside the nest also plays an important defensive role. Pupal odor was extracted from the surface of pupa bodies with methanol. When bioassayed alone, the pupa...

PHOSPHOLIPASE A2 FROM HYMENOPTERAN VENOMS:BIOCHEMICAL CHARACTERIZATION

BIOINSECTICIDE ACTION OF THE VENOM OF AFRICANIZED BEES Apis mellifera LINNAEUS ...

The present paper aimed at testing the action of non-lyophilized venom of Africanized bees Apis mellifera through topical applications on Diatraea saccharalis egg masses. The CL50, DL50 and the most susceptible age of eggs to the venom topic application were also determined. Three-day-old eggs were the most susceptible to the venom action with CL50 equal to 8.6 mg/ml and DL50 equal to 0.173 mg/mass. The venom l...

CHEMICAL COMMUNICATION IN Apis mellifera: TEMPORAL MODULATION OF ALARM BEHAVIORS

The effect of pheromones and their chemical analogues in honeybee alarm behaviors was studied in observation boxes. Defensive behaviors, as follows: a) attraction to scent source, b) elevation of wings in "V", c) abdomen elevation, d) abdomen elevation and pumping and e) first leg pair elevation had been temporarily registered when the following compounds were presented: isoamyl alcohol, octyl alcohol, benzyl a...
