The study aimed at obtaining basic information about estrous cycle in rats treated with dexamethasone, for polycystic ovaries, induced by constant illumination. It was used 30 female rats (Rattus norvegicus albinus) from the lineage Wistar, with 90 days years old, divided according the following groups: Group I rats maintained in a light/dark cycle for 12/12 hours, and after 100 days submitted ...

Molecular descriptors are essential in mathematical chemistry for studying quantitative structure–property relationships (QSPRs), and topological indices a valuable source of information about molecular properties, such as size, cyclicity, branching degree, symmetry. Graph theory has played crucial role the development dominating parameters descriptors. A molecule graph, under graph isomorphism...

Addressing a long-standing question of Albert dating back to 1965, we show that every division algebra has an isotope contains cyclic cubic subfield.

The main question addressed in this paper focuses on the frequency with which the reductions modulo primes of a rational elliptic curve give rise to cyclic groups. This question is part of a broad theme of investigations about the distribution of Frobenius in an infinite family of division fields defined by an elliptic curve over a global field (or in variations of such families in other arithm...

Neonatal seizures pose a high risk for adverse outcome in survived infants. While the prognostic value of amplitude-integrated electroencephalogram (aEEG) is well established in neonates with encephalopathy and asphyxia, neonatal seizure studies focusing on the direct correlation between early aEEG measurement and subsequent neurologic outcome are scarce. In this study, the prognostic value of ...
