The effect of divergent selection for ewe multiple-rearing ability over a 15-year period on mutton quality was examined on the M. longissimus dorsi and M. semimembranosus of entire rams (R) and ewes (E) derived from two Merino lines. The selection of these two lines was based on maternal ranking values for multiple-rearing ability in a positive (P) and negative (N) line. In the negative line th...

Journal of Lipid Research Volume 52, 2011 245 Copyright © 2011 by the American Society for Biochemistry and Molecular Biology, Inc. Essential fatty acids, i.e., linoleic (C18:2n-6) and -linolenic acid (C18:3n-3), which are prerequisites for normal growth, development, and function in mammals, cannot be synthesized de novo and, as such, have to be derived from diet ( 1 ). Subsequently, the C18:2...

BACKGROUND Sporadic and sometimes contradictory studies have indicated changes in satellite cell behaviour associated with the progressive nature of human Duchenne muscular dystrophy (DMD). Satellite cell proliferation and number are reportedly altered in DMD and the mdx mouse model. We recently found that satellite cells in MSVski transgenic mice, a muscle hypertrophy model showing progressive...

The starvation effects on the fatty acids composition of the digestive gland of the scallop Flexopecten glaber were underwent in this study. Results show that food deprivation induces a diminution of the amounts of the EPA (C20:5n-3) and the DHA (C22:6n-3) as well as the n-3/n-6 ratio. Meanwhile, a selective retention, in terms of increase of percentage, of the AA (C20:4n-6) in unfed specimens ...

The breakdown of the Bretton Woods system and the adoption of generalized ‡oating exchange rates ushered in a new era of exchange rate volatility and uncertainty. This increased volatility lead economists to search for economic models able to describe observed exchange rate behavior. The present is a technical Appendix to Cerrato et al. (2009) and presents detailed simulations of the proposed m...

Materials and methods: In Experiment One, a total of 880 pigs (PIC L337 × C22; initially 106.5 ± 0.5 kg) were allotted to four treatments, including doses of 0, 5.0, 7.5, and 10.0 ppm of RAC for 21 days before slaughter. In Experiment Two, 1035 gilts (initially 103.2 ± 0.62 kg) were allotted to nine treatments. Treatments included doses of 5 or 10 ppm RAC for 7, 14, 21, or 28 days before slaugh...

The paper is dedicated to deriving a gaussian procedure to test for cointegration. We consider four alternative specifications, depending on the form adopted by the deterministic terms. We then define the test statistic and derive its asymptotic behaviour under both the null and the alternative hypotheses. We show that, under the null hypothesis, the test procedure follows a Standard-Normal dis...

Employing a probit, logit and gompit model this paper demonstrates that small firm development, represented by a group of structural, behavioral and performance variables determines regional location in Poland. The paper uses original data that samples the small firm stratum in two contrasting regions, Pomorskie and Lubelskie. The following variables were shown to be significantly correlated wi...
