1. Suplementação com análogo de metionina HMB (2-Hidroxi-4-(Metil) ácido Butânico) em dieta de bovinos da raça Nelore terminados em confinamento / Supplementation with HMB (2-hydroxy-4-(methyithio) Butanoic acid) methionine analog in diet of Nellore cattle finished in feedlot
Two experiments were conducted to evaluate the inclusion of levels of HMB (DL, 2-hydroxy-4-(methyl) botanical acid) methionine in diets of Nellore beef cattle finished in feedlot. In Experiment 1, 128 male, unneutered Nellore animals, with initial weight of 290 kg ( 20,50), were housed for 111 days (21 days of adaptation and 90 days of experiment) in 16 pens

2. "Multivariate calibration and differential kinetic analysis in flow systems with spectrophotometric detection" / "Calibração multivariada e cinética diferencial em sistemas de análises em fluxo com detecção espectrofotométrica"
Differential kinetic analysis can be implemented in a flow system analyser, and this was demonstrated in designing an improved spectrophotometric catalytic determination of iron and vanadium in Fe-V alloys. The method relied on the influence of Fe2+ and VO2+ on the rate of the iodide oxidation by Cr2O7 under acidic conditions; therefore the Jones reductor wa

3. Diferentes quantidades de soro de leite na alimentaÃÃo de vacas secas / Different amount of liquid whey in the dry cows diets
O presente trabalho foi dividido em trÃs experimentos distintos para facilitar a organizaÃÃo dos resultados. O primeiro experimento teve como objetivo de criar alternativa simples e barata para os laticÃnios minimizarem a fraude do leite com soro. Foram avaliados o soro doce de leite, obtido pela fabricaÃÃo de queijo tipo GruyÃre e o Ãcido, coletado

4. Efeitos da concentração de matéria seca e do uso de inoculante bacteriano-enzimático, na silagem de tifton 85 (Cynodon spp.), sobre a digestão de nutrientes, parâmetros ruminais e comportamento ingestivo em novilhos de corte em crescimento. / Effects of the dry matter concentration and use of bacterial-enzymatic inoculant, in tifton 85 (Cynodon spp.) silage, on the nutrient digestion, ruminal parameters and ingestive behavior in growing beef steers.
The present trial aimed to study the effects of forage wilting associated or not with a bacterial-enzymatic inoculant on ensiling Tifton 85 grass. Front panel of experimental silos (325 kg square wrapped bales) were daily scored for fungi development and weekly sampled for chemical composition analysis and particle chop length measurements. In a randomized 7

5. Virulence and the Role of Iron in Pseudomonas aeruginosa Infection
The virulence of Pseudomonas aeruginosa can be enhanced by passage in mice or rabbits. Enhanced virulence has some specificity for the host in which the passage is done. Experimental infection in the peritoneal cavity of cannulated rabbits has shown that the injection of iron compounds can lead to a rapid and fatal growth of an otherwise nonlethal dose of ba

6. Effect of methylprednisolone on entry of ampicillin and gentamicin into cerebrospinal fluid in experimental pneumococcal and Escherichia coli meningitis.
The influence of methylprednisolone on the passage of ampicillin and gentamicin into and activity within cerebrospinal fluid was examined in two models of experimental meningitis. Steroid pretreatment reduced the concentrations of these drugs in purulent cerebrospinal fluid of rabbits with experimental pneumococcal and Escherichia coli meningitis (P less tha

7. Studies of the Mechanism of the Antidiarrheal Effect of Codeine
To determine whether the antidiarrheal action of opiate drugs in humans is due to enhanced intestinal absorption rates, as suggested by recent experiments in animals, or is due to altered intestinal motility, as traditionally thought, we studied the effect of therapeutic doses of codeine on experimental diarrhea and on the rate of intestinal absorption of wa

8. Inactivation of Viruses in Bubbling Processes Utilized for Personal Bioaerosol Monitoring
A new personal bioaerosol sampler has recently been developed and evaluated for sampling of viable airborne bacteria and fungi under controlled laboratory conditions and in the field. The operational principle of the device is based on the passage of air through porous medium immersed in liquid. This process leads to the formation of bubbles within the filte

9. Binding of Ferric Enterobactin by the Escherichia coli Periplasmic Protein FepB
The periplasmic protein FepB of Escherichia coli is a component of the ferric enterobactin transport system. We overexpressed and purified the binding protein 23-fold from periplasmic extracts by ammonium sulfate precipitation and chromatographic methods, with a yield of 20%, to a final specific activity of 15,500 pmol of ferric enterobactin bound/mg. Peripl

10. Transplacental pharmacokinetics of dideoxyinosine in pigtailed macaques.
To determine whether dideoxyinosine is actively transported across the placenta, four pregnant macques (Macaca nemestrina) near term and their fetuses were infused intravenously in random order with simultaneous doses of dideoxyinosine (42.5 micrograms/min/kg of body weight) and antipyrine (41.7 micrograms/min/kg) for 30 h. The infusions took place after the

11. Peripheral metabolism of insulin, proinsulin, and C-peptide in the pregnant rat.
To clarify alterations in carbohydrate metabolism which occur in pregnancy, metabolic clearance rates of insulin, proinsulin, and C-peptide were measured by the constant infusion technique in term-pregnant rats and in virgin littermates. In addition, placental permeability to these peptides was evaluated by simultaneous determination of their concentration i

12. Circulating and intra-articular immune complexes in patients with rheumatoid arthritis. Correlation of 125I-Clq binding activity with clinical and biological features of the disease.
The correlation between the incidence and level of immune complexes in serum and synovial fluid and the various clinical and biological manifestations of rheumatoid arthritis has been studied. Immune complexes were quantitated using a sensitive radioimmunoassay, the 125I-Clq binding test, in unheated native sera and synovial fluids from 50 patients with sero
