Valor nutricional da soja integral tostada e extrusada para poedeiras comerciais

An experiment was conducted to determine the apparent nitrogen-corrected metabolizable energy (AMEn) values and the coefficients' metabolization of the: dry matter, ether extract, calcium and phosphorus availabilities of experimental layer diets containing toasted (TSB) and extruded (ESB) soybeans. The soybean meal (SBM) was substituted at 0, 50, and 100% by TSB and ESB whole soybeans. The whole soybeans utilization in layer diets did not adversely affect calcium and phosphorus availability. The SBM and ESB, in diets with crude protein at 17%, showed the best ether extract coefficients of metabolization. When TSB replaced all SBM in the diets, it was observed the worst value for AMEn.

O EEG na insuficiencia renal cronica. III. Valor prognostico

In 1983 and 1984 we performed a longitudinal 1-year follow-up study of 15 patients with chronic renal failure, 8 of whom were on hemodialysis and 7 on peritoneal dialysis. The EEG abnormalities of these patients were catalogued and filed and the patients' medical records were examined 5 years later for an analysis of their clinical evolution. Old age EEG findings were detected in young patients with chronic renal failure who died. We conclude that old age EEG findings in patients of any age with chronic renal failure represent a poor prognosis. In contrast, EEG asynchronies are associated with severe uremic encephalopathy but are reversible, since these phenomena were fully reversed together with all clinical alterations in a patient who later received a renal transplant.

Valor nutricional do farelo de algodão para alor a tilśpia do nilo (Oreochromis niloticus)

Cottonseed meals (CSM) with different protein levels (35, 39 and 40%) were evaluated to determine their chemical composition and measure apparent digestibility coefficients (ADC) of dry matter, protein, amino acids, energy, lipid and minerals for Nile tilapia. Apparent digestibility coefficients were determined using a reference purified diet containing 0.1% of chromic oxide indicator, and test diets contained 60% of reference diet and 40% of test ingredients. Results showed that apparent digestibility coefficients of cottonseed meals were different (p < 0.05). The apparent digestibility coefficients were: dry matter, 53.45-54.32%; crude protein, 71.56-74.81%; energy, 53.80-58.60%; lipid, 85.37-89.11%; phosphorus, 33.75-34.50%; calcium, 41.21-43.75%; iron, 62.02-79.85%; zinc, 0-67.41%; copper, 13.37-14.27%; essential amino acids, 71.39-79.17%; and non-essential amino acids, 77.08-82.58%. The ADC of protein did not reflect the majority of amino acids ADC showing variation in individual digestibility of amino acids and among cottonseed meals. Cottonseed meal can be used as protein succedaneum in Nile tilapia diets.

Valor preditivo do potencial de implantação embrionário pela análise do perfil químico de meios de cultivo por espectrometria de massas (ESI-Q-ToF)

Objective: This case-control study analyzed mass spectrometry fingerprinting patterns of culture media samples used for embryo culture to predict embryo implantation. Methods: The culture medium harvested after embryo transfer of 22 embryos from 13 patients was used for the experiments. After embryo transfer, the remaining culture media were collected and samples were split in positive (n=8) and negative (n=14) implantation groups according to implantation outcomes (100% or 0% of implantation). Samples were individually diluted and injected directly to the Electrospray ionization (ESI) MS coupled to a Quadrupole Time-of-flight MS (Q-ToF-MS).Ions relative intensities of each spectrum were considered. Data analysis was conducted in MatLab 7.0 version using Partial Least Squares - Discriminant Analysis toolbox. Results: There were 3027 observed ions at 100% and 0% implantation groups by ESI-Q-ToF-MS. The statistical model could categorize the samples in two clusters, based on their positive and negative implantation outcomes. Less intense ions present in the mass spectra with statistical significance have contributed to the major differences to group distinction. Conclusions: Positive and negative implantation embryos showed a specific biochemical pattern present in culture media, which could be detected as a fast, simple and non-invasive way. This biochemical profile could help the selection of the most viable embryo, improving single embryo transfer and thus eliminating the risk and undesirable outcomes of multiple pregnancies. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.

O uso do pool de plasma caseiro interfere no valor da rni?

Introduction: The prothrombin time (PT) test is commonly used to monitor anticoagulant levels in patients undergoing oral anticoagulant therapy. Currently, anticoagulation levels have been assessed through the international normalized ratio (INR) value. Objective: The objective of this study was to determine if inhouse preparations of polled plasma, containing five (P5) and 20 (P20) samples, respectively, may be used as normal control of PT and to assess its interference in INR values. Material and methods: The experiment was performed in 32 days. Both polled plasma preparations were analyzed in comparison with a commercial control (PC). PT was performed for PC, P5 and P20 daily and the INR value for PC, P5 and P20 was assessed in patients undergoing oral anticoagulant therapy. The applied statistical tools were mean value (X), analysis of variance and Tukey test. Results: There were no statiscally significant differences in PT and INR for PC, P5 and P20. Conclusion: In-house polled plasma (P5 and P20) may be applied as normal control of PT and it does not interfere in the INR value.
