Genetic diversity analysis of two commercial breeds of pigs using genomic and pedigree data.

Background: Genetic improvement in livestock populations can be achieved without significantly affecting genetic diversity if mating systems and selection decisions take genetic relationships among individuals into consideration. The objective of this study was to examine the genetic diversity of two commercial breeds of pigs. Genotypes from 1168 Landrace (LA) and 1094 Large White (LW) animals from a commercial breeding program in Brazil were obtained using the Illumina PorcineSNP60 Beadchip.

[True capsular exfoliation: report of two cases].

We report two cases of true capsular exfoliation occurring in elderly patients with no known history of prolonged heat exposure or intraocular inflammation. The biomicroscopic aspects, histopathologic findings and possible surgical implications are discussed.
