Andréia Dalla Rosa, Nelson G. Golynski, Mário L. Teixeira
Advances in Microbiology (AiM) , 2014, DOI: 10.4236/aim.2014.49054

The degradation of industrial residues is of great importance for the maintenance of the environment. Therefore, the objective of this study is to verify the proteases production for bacteria of the gender isolated Bacillus of soil. The samples of skin residue were collected in industries of the area west of Santa Catarina, using residue of skin rude swine and residue of skin processed swine. The verification of the biotechnological potential consisted of the use of these residues in middle of culture and inoculation of the respective species of bacteria. The results were more expressive in the samples of skin processed swine, where it showed a degradation average around 43.55% (p/p). While, in the samples of residue of skin rude swine, an average of degradation of 20.60% (p/p) happened. In this way, the residue of skin processed swine is more sensitive than the catalytic activity of the bacterial enzymes.

Abstract: thyrotoxicosis is confirmed by high serum total or free triiodothyronine (t3/ft3) and thyroxine (t4/ft4) and low serum thyrotropin (tsh) concentrations. in endemic areas, a predominant increase of t3 with normal or low t4 and ft4 can be found, referred to as "t3-thyrotoxicosis". one variant, known as "free t3-toxicosis" has recently been described presenting subnormal serum tsh, normal ft4 and total t3 concentrations, but high serum ft3. thyrotoxicosis increases bone turnover, especially resorption, with bone loss and increases fracture rates; involves the cardiovascular system both in systemic hemodynamics and t3-mediated effects on cardiac myocite-specific gene expression. detecting t3- thyrotoxicosis is important because of the high morbidity, increased risk of osteoporosis and arrythmias. thus, the early diagnosis and treatment of the hyperthyroidism can prevent complications. we studied three patients with criteria for t3-toxicosis - one of them with ft3 toxicosis. they live in areas with adequate iodine intake and all three present with diffuse goiter. because the screening for thyroid diseases only measures ft4 and tsh, we suggest that patients with subnormal tsh levels and normal ft4 should be worked up with measurement of total t3. if normal, a ft3 can be obtained to identify ft3 toxicosis. the study of such cases must continue to provide valuable insights into the thyrotoxicosis.

Abstract: in the present work three ferroin reagents were studied for the simultaneous spectrophotometric determination of iron and copper: 1,10-phenanthroline, 2,2'-bipyridine and 2,4,6-tri(2-pyridyl)-1,3,5-triazine. effect of ph, conditions, order reagent addition, interferences, amount of reagents, lineal range, sensitivity and stability of each system were compared. the 2,4,6-tri(2-pyridyl)-1,3,5-triazine can be used for determination of iron in the presence of copper with a detection limit of 5 μg l-1 and coefficient of variation of 2.0%; however it was not possible to determine directly copper in the presence of iron with this reagent. 1,10-phenanthroline can be used for simultaneous determination of the metallic ions with detection limits of 7 and 8 mg l-1 and coefficients of variation of 1.8 and 2.3% in the determination of iron and copper, respectively. the results showed also that 2,2'-bipyridine can be used for simultaneous determination of the metallic ions with detection limits of 11 and 32 μg l-1 and coefficients of variation of 1.9 and 2.5% in the determination of iron and copper, respectively. the reagents were used for spectrophotometric determination of iron and copper in ethanol fuel.

Abstract: in a field trial involving 68 rubber tree (hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth a and for age 7 to 12 (mature period) for girth b and for age 7 to 12 (production of latex) for yield. rank correlation coefficients between all immature ages of girth (girth a), all ages of mature girth (girth b) and all annual rubber production (yield) were significant for the three traits, with the coefficients decreasing with increasing age. selection of the sets of best 30, 15, 10 and 5 clones from the available 68 clones at a given age was generally accompanied by a descending order of percentage success. it was suggested: (a) to have the best 30 clones of age 6, select the set of best 36 clones at age 2, (b) to have the best 15 clones of age 6, select the set of best 20 clones at age 3, (c) to have the best 5 clones of age 6, select the set of best 8 clones at age 4, and (d) to have the best 3 clones of age 6, select the set of best 3 clones at age 5. more than 80% of the targeted clones on girth a or girth b basis and more than 76.7% clones on yield basis were found to get selected at steps (a) through (d). for achieving early multiplication of the most productive clone for deployment, multiplication should be started with the best 36 (i.e. 60%) clones selected at age 2.

Abstract: the aims of this work were to estimate the coefficient of relatedness within families and the genetic parameters for growth related traits in a progeny test from an open-pollinated variety of pinus caribaea morelet hondurensis barret & golfari, established in mato grosso do sul state, brazil. the experimental design was the triple 10 x 10 lattice, with 96 families, three replicates, and ten plants per plot. fourteen years after planting, the trial was measured for the following traits: total height, diameter at breast height (dbh), and true volume. the estimation of coefficients of relatedness within family from microsatellite loci indicated that families are true half-sibs (^rxy = 0.253). thus, the additive genetic variance (σ2a) can be estimated assuming that the genetic variance among progenies (σ2p) accounts for ? of additive genetic variance (^σ2a = 4^σ2p). the estimative of heritability coefficients at individual level (hi2) was relatively high (0.28 for dbh and 0.44 for height). the heritability coefficient considering the average families (hm2) was also high, ranging among the traits from 0.50 to 0.58. these results suggest that the population can be improved by both massal and among families selection. additionally, the estimated genetic gains with sequential selection among and within families were high (ranging from 8.92% for height to 37.56% for volume), demonstrating that this method of selection can generate high genetic improvement.

Abstract: the objective of this study was to assess genotype-year interaction and determine temporal stable genotypes across six years of rubber yield evaluation. stability analyses were performed by eberhart and russell method for rubber yield. twenty-five genotypes were analyzed in a randomized complete block design with three replications. the best genotype in one year was not same always in the other year. the genotype components were partitioned into linear (genotypes within year) and nonlinear (pooled deviations) components. significant mean square for linear components was predictable. this indicated that the performance of genotypes across the years for rubber yield could be predicted. among the analyzed genotypes the iac 40 also was considered highly productive and vigorous, with suitable adaptation.
