Study of different structures of additive genetic groups to increase the efficiency of genetic selection in beef cattle

G. A. Oliveira Junior, “Study of different structures of additive genetic groups to increase the efficiency of genetic selection in beef cattle”, vol. 13. pp. 115-116, 2014.

The structure of genetic groups is a technique that allows animals with unknown pa­ternity to be included in genetic evaluation programs. The ways these groups are formed are still arbitrary, making it important to study different formation strategies for genetic groups, aiming for a suitable framework for the genetic evaluation of seedstock in animal breeding programs.

Correlation of serum high-sensitivity C-reactive protein and interleukin-6 in patients with acute coronary syndrome

X. H. Wang, Liu, S. Q., Wang, Y. L., and Jin, Y., “Correlation of serum high-sensitivity C-reactive protein and interleukin-6 in patients with acute coronary syndrome”, vol. 13, pp. 4260-4266, 2014.

Serum high-sensitivity C-reactive protein (hs-CRP) is a sensitive indicator of inflammation, which is closely related with the progress of plaque formation. Interleukin-6 (IL-6) is one of the inflammatory markers of local coronary plaque and the peripheral blood cycle, promoting the occurrence of atherosclerosis development and plaque rupture. In this study, the correlation of hs-CRP and IL-6 was investigated in patients with acute coronary syndrome (ACS).

Variations in genotype-phenotype correlations in phenylketonuria patients

L. L. Santos, Fonseca, C. G., Starling, A. L. P., Januário, J. N., Aguiar, M. J. B., Peixoto, M. G. C. D., and Carvalho, M. R. S., “Variations in genotype-phenotype correlations in phenylketonuria patients”, vol. 9, pp. 1-8, 2010.

Phenylalanine hydroxylase deficiency is a trait inherited in an autosomal recessive pattern; the associated phenotype varies considerably. This variation is mainly due to the considerable allelic heterogeneity in the phenylalanine hydroxylase enzyme locus. We examined the genotype-phenotype correlation in 54 phenylketonuria (PKU) patients from Minas Gerais, Brazil. Two systems were used. The first was a phenotype prediction system based on arbitrary values (AV) attributed to each mutation and the second was a correlation analysis.

RAPD-based genetic diversities and correlation with morphological traits in Camellia (Theaceae) cultivars in China

X. F. Wang, Zheng, H. Y., Zheng, W. H., Ao, C. Q., Jin, H. Y., Zhao, L. H., Li, N., and Jia, L. R., “RAPD-based genetic diversities and correlation with morphological traits in Camellia (Theaceae) cultivars in China”, vol. 10, pp. 849-859, 2011.

Camellia is an economically important ornamental plant that has many uses, such as in beverages, foods and medicines. We examined 15 Camellia cultivars in Wenzhou, China, using RAPD markers and measurements of three traits (petal color, flower diameter, blooming period). PCR amplification with 15 random primers produced 1935 bands, observed at 88 amplification loci; 77% of the amplified loci were polymorphic, with a mean of 4.5 polymorphic loci per primer.

Estimation of genetic parameters and variance components for growth traits in Romosinuano cattle in the Colombian humid tropics

R. M. Sarmiento and Garcia, J. P., “Estimation of genetic parameters and variance components for growth traits in Romosinuano cattle in the Colombian humid tropics”, vol. 6, pp. 482-491, 2007.

(Co)variance components and genetic parameters were estimated for body weights of a Romosinuano herd located in Sinú Valley, Cordoba, Colombia. Restricted maximum likelihood methods were used with a univariate animal model for birth weight, weaning weight (270 days), 16-month weight (480 days), weaning daily gain, and post-weaning daily gain. Models included random animal direct and maternal genetic effects, maternal permanent environmental effect (c2), and sex-year-month of birth and age of dam, as fixed effects.
