The genome sequence of a strain of Vibrio parahaemolyticus holds 11 copies of rRNA operons (rrn) with identical 16S rRNA genes (rrs). Conversely, the species type strain contains two rrs classes differing in 10....

Polymorphism in gene coding for ACE determines different development of myocardial fibrosis in rats

Ocaranza, María Paz;Díaz Araya, G.;Carreño, J. E.;Muñoz, David;Riveros, Juan Pablo;Jalil Milad, Jorge;Lavandero, Sergio (2004-02-01)

In humans, the effect of angiotensin-converting enzyme (ACE) gene polymorphisms in cardiovascular disease is still controversial. In the rat, a microsatellite marker in the ACE gene allows differentiation of th....

Polymorphisms in the mitochondrial aldehyde dehydrogenase gene (Aldh2) determine peak blood acetaldehyde levels and voluntary ethanol consumption in rats.

Quintanilla, María Elena;Tampier, Lutske;Sapag, Amalia;Israel, Yedy (2005)

Regulatory T cells (Treg) are important in the development of immune tolerance under normal physiological conditions. However, in pathological situations such as cancer, Treg increases have been correlated wi....

Polynomial time recognition of unit circular-arc graphs

Durán, Guillermo;Gravano, Agustín;McConnell, Ross M.;Spinrad, Jeremy;Tucker, Alan (2006-01)

We present an efficient algorithm for recognizing unit circular-arc (UCA) graphs, based on a characterization theorem for UCA graphs proved by Tucker in the seventies. Given a proper circular-arc (PCA) graph G,....

Poly(N-phenylmaleimide-co-acrylic acid)-copper(II) and poly(N-phenylmaleimide-co-acrylic acid)-cobalt(II) complexes: Synthesis, characterization, and thermal behavior
