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.

Divergência genética de genótipos de feijoeiro a infestação de Zabrotes subfasciatus (Bohemann) (Coleoptera: Bruchidae)

The aim of this work was to evaluate the genetics divergence of bean genotypes in relation to the oviposition, feeding and development of Zabrotes subfasciatus, determining the degrees of resistance to the weevil. The genotypes used were: IAC Carioca-Tybata, IAC Fortaleza, IAPAR 81, IAC Carioca-Ete, IAC Galante, IAC Harmonia, IAC Una, IAC Diplomata, BRS Supremo and RAZ 49. Tests were performed in laboratory under controlled humidity, temperature and photophase conditions. In free choice test, 10 g of bean genotypes seeds were distributed in circular openings placed equidistant from each other in aluminum trays, where 70 couples were released. The attractiveness was evaluated 24 hours and seven days after the experiment started, and then the number of eggs was evaluated. In non choice test, 10 g of seeds were used where seven couples of Z. subfasciatus, 24 hours-old, were released, remaining seven days, and after the adults retreat, the total number of eggs, viable and unviable eggs, the number and percentage of emerged adults, weight, longevity and period from egg to adult of males and females, sex ratio, dry mass and dry mass consumed by insect were evaluated. In the genotype IAC Harmonia was observed the lower oviposition; RAZ 49 was the most non preference-type resistant for feeding and/or antibiosis-type resistant; BRS Supremo, IAC Carioca-Ete and IAPAR 81 are no preference for feeding and/or antibiosis-type moderate resistant; IAC Galante is susceptible and the other genotypes are highly susceptible to Z. subfasciatus.

Acúmulo de silício na parte aérea de cultivares de arroz de terras altas afetado pela aplicação de silicato e carbonato no solo

Even the element silicon being the most uptake by rice plant, many benefit effect like: increase of pest and disease tolerance, decrease of lost of water by transpiration and better the leaf architecture becoming the leafs more erect, resulting as well at the better photosynthesis efficacy. There is not too much knowledge about the uptake march in upland rice plants. This study aimed to evaluate the content of silicon in two upland rice cultivars by the influence of the application of silicate and limestone at the soil. The experiment was carried in Hapludox soil in a completely randomized experimental design in 2x2x7 factorial scheme in four replications. The treatments were consisted of calcium silicate fertilizer and limestone in interaction with seven period of physiological stage, using the upland rice cultivars Caiapo and Maravilha. At the cultivar Maravilha Si accumulation begin from tillering and achieve it better value at the microsporogenesis, while the Caiapo cultivar, occurs between tillering until the mily grain. Caiapo shows efficient Si accumulation when it was supplied to the soil. Plant organs that more accumulated silicon in both upland rice cultivars followed decreased order: stem > leaf > panicle.

Influência ao consumo crônico de álcool no fêmur de ratos machos e fêmeas

Considering that alcohol has been identified, in the literature, as an evident risk factor for osteoporosis development, inducing loss of bone mass, the aim of this study was to evaluate the effect of the alcohol on the femur of male and female rats. For this purpose, 35 male and 35 female rats, divided into seven groups of five animals per genera were included. The groups were: control group that received food and water as much as they wished; alcohol group in the concentrations of 10, 20 and 30% and the isocalorie: groups corresponding to the concentration of alcohol. After 8 weeks, the animals were sacrificed and evaluated regarding to the body weight and nutritional conditions. Unilateral femurs were removed and analyzed in relation to the length, width, and thickness of the bone cortical, trabeculae percentage and optical density. Data obtained were analyzed by ANOVA (Tukey; p<0.05). Regarding to the weight, loss of weight was observed in the animals of the group alcohol 20% among females and 30% among the males. In relation to the nutritional conditions, the females with the dosages of 10, 20 and 30% of alcohol swallowed a mean of 25, 39 and 53% of Kcall and the males 22, 36 and 45 Kcal Jday coming from the alcohol. Alcohol reduced the length of the femur only in the group MG6. Mesio-distal width was higher in the group FG6 although the antero-posterior width was not modified. The cortical thickness among males and females was not altered however the percentage of trabeculae bone was reduced among females alcohol 30% and among males with the three alcoholic concentrations. Optical density was reduced in the concentration of 30% among the males and females. Under the experimental conditions, it could be concluded that the effect of alcohol was more evident among the males and in the trabeculae bone, and that the alcoholic concentration of 30% was the most harmful for the bone tissue, ....

Quantificação da desintegração de comprimidos por fluxo ótico em seqüências de imagens de biosusceptometria AC

AC Biosusceptometry (ACB) is a low-cost biomagnetic tool that has been successfully applied on pharmaceutical research to evaluate performance of solid dosage forms. The aim of this work was to evaluate the Horn & Shunck method to access tablet disintegration. To evaluate the HS results was record on video a test with a objet moving in a rail with a constant velocity. The desintegration was recorded on video and ACB, which used have seven pairs of detection coils and a pair of excitation coils to mensure the magnetic ux variation. The signals were ampli ed and digitalized to create images, which were restored by Wiener lter, while the video images are converted to gray scale, both are normalized and binarized and had the optical ow estimation calculated by Horn & Schunck (HS) algorithm. All signals and images are processed and developed algorithm on Matlab. During the tests the ve tablets (500mg ferrite, 375mg excipients, compression 10 to 50 kN) were on a becker between of the ACB system and of the video system, and only touching the surface of the water. With all OF maps calculated was realized the sum of the resultants of each, to get a disintegration process resultant for each compression. Whit that was possible observed the disintegration behaves. For the compression force study the HS components of each sequence was sum, take mean and normalized for sequence's max modulo, therefore can be observed a high growing on less compression tablets. We can conclude the HS algorithm is viable to tablets disintegration data collection and whit that was possible to create a tablets disintegration analyzes protocol, which would be useful on desintegration kinetics study
