Qualidade da água para a irrigação de plantas em viveiros: utilização de descargas elétricas sem efeito térmico e de campos de energia no controle de Meloidogyne incognita Raça 1

The effect of electrical discharges without thermic effect and of energy field on Meloidogyne incognita Rara 1 larvae elimination in weir water was tested. on an average, 63,22% of larvae were killed by electrical discharges, in comparison with 53,12% of dead larvae in the control (water that received only ammonium sulphate) as an electrolyte. Water exposed to energy fields presented higher percentages of dead larvae (50,01% for electromagnetic field, 43,78% for variable electric field and 40,48% for static electric field) in comparison with control, represented by water without exposition to any energy field and without ammonium sulphate (34,27%).

Myosin heavy chain expression and atrophy in rat skeletal muscle during transition from cardiac hypertrophy to heart failure

The purpose of this investigation was to determine whether changes in myosin heavy chain (MHC) expression and atrophy in rat skeletal muscle are observed during transition from cardiac hypertrophy to chronic heart failure (CHF) induced by aortic stenosis (AS). AS and control animals were studied 12 and 18 weeks after surgery and when overt CHF had developed in AS animals, 28 weeks after the surgery. The following parameters were studied in the soleus muscle: muscle atrophy index (soleus weight/body weight), muscle fibre diameter and frequency and MHC expression. AS animals presented decreases in both MHC1 and type I fibres and increases in both MHC2a and type IIa fibres during late cardiac hypertrophy and CHF. Type IIa fibre atrophy occurred during CHF. In conclusion, our data demonstrate that skeletal muscle phenotype changes occur in both late cardiac hypertrophy and heart failure; this suggests that attention should be given to the fact that skeletal muscle phenotype changes occur prior to overt heart failure symptoms.

Determinação bromatológica de Pleurotus ostreatus cultivado em resíduos de diferentes cultivares de bananeira

The objective of this work was to evaluate the nutritional composition (raw protein, ether extract, raw fiber, FDA, FDN and ash) of the POS 09/100 strain of Pleurotus ostreatus grown in three combinations of residues (pseudo-stem, leave and pseudo-stem + leaf) and four banana tree cultivars (Thap maeo, Prata ana, Pelipita and Caipira). The basidiomata harvested were submitted to dehydration in a forced ventilation stove with temperature adjusted to 40 degrees C until reaching constant weight, being then grinded in a knife mill. The method proposed by Kjeldahl (1883) was used to determine total nitrogen. The Weende method (AOAC, 1997) was employed to determine crude fiber, acid-detergent fiber (ADF) and neutral detergent fiber (NDF). According to the results obtained, crude protein, ash, ADF and NDF contents varied with the kind of residue and banana tree cultivar; the substrate prepared with leaves of banana tree (Prata Ana cultivar) yielded the highest crude protein (35.4%) and ash (6.7%) contents in the basidiomata of P. streams; the substrate prepared with pseudo-stein of banana tree (Prata Ana cultivar) provided the highest ADF (31.6%) and NDF (41.9%) contents in the basidiomata of P. ostreatus. Ether extract and crude fiber contents of P. ostreatus didn't vary in function of the treatments, with averages of 2.45 and 11.27%, respectively.

Viabilidade de crescimento micelial de Coprinus comatus em meio de cultura à base de resíduos orgânicos

The objective of this work was to evaluate the mycelial growth of the Coprinus comatus strain CCO 01/01 in culture based on organic residues of Saccharum officinarum (sugarcane bagasse), Citrus sinensis (orange bagasse), Ananas comosus (pineapple residues) and Musa sp. (banana leaf), supplemented with wheat bran in the proportions of 0, 10 and 20%, kept at 27 degrees C. The mycelial growth of C. comatus was evaluated daily by measurement of the diameter of the colony during seven days of incubation. The banana leaf was considered the best residue for the cultivation of the C. comatus even without supplementation, meaning lower production costs. The supplementation of pineapple residues with 10% of wheat bran favored fungi growth. Sugar-cane bagasse was suitable for the growth of the C. comatus provided it is enriched with wheat bran. The orange bagasse, without pH correction, was not appropriate for the mycelial growth of C. comatus.
