A thermostable lipase was partially purified from the culture supernatant of a thermophilic Bacillus sp. The enzyme is optimally active at 60ºC and pH 8.0. The enzyme showed enhancement in activity in presence of benzene or hexane (30% v/v each). The activity (assayed by determining the release of pNP from pNP laurate) was stimulated up to 60% of these solvents in enzyme reaction mixture. The catalytic properties of this thermostable enzyme can be further improved via the use of different immobilization techniques and reaction conditions. Enzyme was immobilized on different solid supports and their enzyme activity and stability was compared. The enzyme was adsorbed on silica and HP-20 beads followed by cross-linking with gluteraldehyde on HP-20,... |

Una marea negra provocada por el vertido deliberado o accidental de crudos de petróleo, aceite combustible, fangos o residuos petrolíferos y productos refinados, provoca un gran impacto sobre los ecosistemas marinos y costeros. En este trabajo, se desarrolla un producto compuesto por bacterias marinas inmovilizadas por atrapamiento en k- carragenina semirrefinada y en cuya formulación no se incluyen nutrientes. Los resultados muestran que la variante de inmovilización más ventajosa se obtuvo cuando fue empleada la κ-carragenina al 1% gelificada con una solución de KCL 1.5 M. Mediante análisis de Cromatografía Gaseosa de Alta Resolución y de espectroscopia (FTIR), se demostró la alta capacidad de degradación del bioproducto frente a petróleo del Yacimiento... |

The objective of the present study was to propose an orthosis of light material that would be functional for the animal and that would maintain only the ankle joint immobilized. Male Wistar rats (3 to 4 months old, 250-300 g) were divided into 2 groups (N = 6): control and immobilized for 7 days. Rats were anesthetized with sodium pentobarbital (40 mg/kg weight) and the left hindlimb was immobilized with the orthoses composed of acrylic resin model, abdominal belt and lateral supports. The following analyses were performed: glycogen content of the soleus, extensor digitorum longus, white gastrocnemius, red gastrocnemius, and tibialis anterior muscles by the phenol sulfuric method, and the weight, fiber area and intramuscular connective tissue of the soleus... |

Em solos com elevado grau de intemperismo, a imobilização temporária de fósforo pela biomassa microbiana do solo (BMS) pode ser um mecanismo de retardamento das reações de adsorção. O objetivo do presente trabalho foi avaliar a amplitude no fósforo microbiano (Pm) em um Argissolo em pastagem nativa submetida à roçada, introdução de forrageiras exóticas e adubadas com fertilizantes fosfatados. O estudo foi desenvolvido a partir de um experimento instalado em 1997 que constava de cinco tratamentos de fosfato e calagem (testemunha sem fósforo; hiperfosfato de gafsa; superfosfato triplo; superfosfato triplo + calcário e superfosfato simples + calcário), distribuídos em quatro blocos ao acaso. Em junho de 2002, a pastagem nativa remanescente foi roçada, semeada... |

The objective of the present study was to determine to what extent, if any, swimming training applied before immobilization in a cast interferes with the rehabilitation process in rat muscles. Female Wistar rats, mean weight 260.52 ± 16.26 g, were divided into 4 groups of 6 rats each: control, 6 weeks under baseline conditions; trained, swimming training for 6 weeks; trained-immobilized, swimming training for 6 weeks and then immobilized for 1 week; trained-immobilized-rehabilitated, swimming training for 6 weeks, immobilized for 1 week and then remobilized with swimming for 2 weeks. The animals were then sacrificed and the soleus and tibialis anterior muscles were dissected, frozen in liquid nitrogen and processed histochemically (H&E and mATPase).... |

The aim of the present study was to evaluate the effect of joint immobilization on morphometric parameters and glycogen content of soleus muscle treated with clenbuterol. Male Wistar (3-4 months old) rats were divided into 4 groups (N = 6 for each group): control, clenbuterol, immobilized, and immobilized treated with clenbuterol. Immobilization was performed with acrylic resin orthoses and 10 µg/kg body weight clenbuterol was administered subcutaneously for 7 days. The following parameters were measured the next day on soleus muscle: weight, glycogen content, cross-sectional area, and connective tissue content. The clenbuterol group showed an increase in glycogen (81.6%, 0.38 ± 0.09 vs 0.69 ± 0.06 mg/100 g; P < 0.05) without alteration in weight,... |
