Uso de resíduos de madeiras e frutos da amazônia para o cultivo in vitro do cogumelo comestível shiitake

Local abundant residues with low or without commercial value with potential to make the production of edible mushrooms economically viable in any region of Brazil must be employed for cultivation. Thus, the radial mycelial growth of LED 20 strain of Lentinula edodes (Berk.) Pegler was verified in culture media prepared with extract of regional residues by using substrates based on Protium puncticulatum, Cariniana micrantha and Caryocar glabum sawdust, supplemented with 20% of grinded residues from the barks of the fruits of Astrocaryum aculeatum and Theobroma grandiflorum. Residues from eucalyptus (Eucalyptus spp) sawdust and wheat bran (Triticum aestivum L) were used as witness because they are commonly used in the cultivation of L. edodes. The experimental design used was totally randomized, in 4x3 factorial scheme, totalizing 12 treatments with five repetitions, being that each repetition corresponded to a Petri dish, adding up a total of 60 dishes, which were incubated under 25 degrees C. The diameter of the colony was daily evaluated during seven days of incubation. After that period, it was verified that media prepared with P. puncticulatum extract, whose supplementation with both brans was favorable for fungic development, presented some of the highest averages of mycelial growth of LED 20 strain of L. edodes, confirming the potential of those residues.

Lethal effect of high concentrations of Parecoxib and Flunixin meglumine on the in vitro culture of bovine embryos

Since cyclooxygenase (COX) inhibitors have been pointed out as potential treatments to increase pregnancy rates after embryo transfer, the present experiment aimed to evaluate the effects of flunixin meglumine (FM) and parecoxib (P), a COX-1 and 2 or COX-2 specific inhibitor, respectively, on the development of bovine embryos until the hatched blastocyst stage. In vitro produced bovine embryos were cultured in media with different concentrations of FM (0.14; 1.4; 14; 140 or 1400 mu g/ml) or P (0.09; 0.9; 9; 90 or 900 mu g/ml) and the production rates were evaluated. Concentrations of FM <= 14 mu g/ml and P <= 90 mu g/ml did not impair embryo development, although compiled data from non-lethal FM concentrations (<= 14 mu g/ml) indicated a toxic effect enough to decrease the hatching rate of blastocysts. Concentrations of FM at 140 and 1400 mu g/ml and P at 900 mu g/ml were lethal as no cleavage was detected on presumptive zygotes.

Influência da luz LED na cultura celular de Mieloma múltiplo murino–NS1 in vitro

A monoclonal antibody (mAb) is an important tool in medical biotechnology and the production of biopharmaceuticals, especially for disease diagnosis and treatment of infections, because the antibodies have a significant advantage over chemical agents used in conventional therapies . The last thirty years the technology of production of monoclonal antibodies developed mainly the technique of obtaining in vitro, but also of their production is laborious, the cost is high. A major element of the high cost of production is the fact that the long-term culture consumes a large amount of imported inputs with high added value. A major contribution of this work is to promote cell growth more quickly and efficiently. Currently, a great race to discover new technologies and techniques to synthesize new antibodies and significantly increase the production of murine mAbs. New technologies such as laser and LED are innovations and widespread in modern life, so much so that its use has proliferated worldwide, primarily in the medical field. Recent studies show a series of results from the influence of the LED light in biological tissues such as: increasing the rate of cell proliferation, increased production rate of fibroblasts, increasing the rate of synthesis of RNA and DNA synthesis of ATP, etc. To assess the contribution of the LED in the culture of Myeloma NS1murino compared to the standard procedure. - NS1 cells were provided and followed the criteria of culture medium of the Laboratory of Cellular Engineering Center of Botucatu (POPs). The same amount of cells was grown in bottles of 25 cm2 polystyrene Tissue Culture Treated, specifically marked and kept in special medium RPMI 1640 Gibco BRL  supplemented with fetal bovine serum 10%, essential amino acids and non-essential, glucose, insulin and antibiotics. It was used in LEDs Cromatek wavelength of 630nm, 475nm and 530nm. The groups were... (Complete abstract click electronic access below)
