TL;DR: The findings indicate that a more comprehensive seroprevalence study is needed to determine the prevalence of HTLV-I1 infection among Brazil’s diverse and distinct populations, and nationwide screening of blood donors should be continued.
Journal ArticleDOI
Interleukin 8 as a vaso-occlusive marker in Brazilian patients with sickle cell disease
Marilda Souza Goncalves,I. L. Queiroz,S. A. Cardoso,A. Zanetti,A.C. Strapazoni,Elisângela Vitória Adorno,A. Albuquerque,Alexandre J. Santana,M.G. dos Reis,Aldina Barral,M. Barral Netto +10 more
TL;DR: It is concluded that in the studied population, IL-8 concentration may be a useful VOC marker, although the mechanism of the pathogenic process of sickle cell VOC syndromes remains unclear.
Journal ArticleDOI
The Homotopy Type of Lie Semigroups in Semi-Simple Lie Groups
TL;DR: In this article, it was shown that there exists a compact and connected subgroup of a semi-simple Lie group such that the subgroup is isomorphic to the original Lie group.
Journal ArticleDOI
Controllability Properties and Invariance Pressure for Linear Discrete-Time Systems
TL;DR: In this paper, a unique control set with non-void interior and bounded in the hyperbolic case is presented, and a formula for the invariance pressure of this control set is proved.
Journal ArticleDOI
Invariance Pressure for Control Systems
TL;DR: In this paper, the equivalence between inner invariance pressure based on spanning sets of controls and on invariant open covers has been shown for a class of linear systems, and a number of properties of invariance pressures are derived.
