Upside-Down and Inside-Out Signs in Uterine Inversion
Uterine inversion is a rare condition that is accompanied by massive hemorrhaging and shock, resulting in a maternal emergency. The diagnosis of uterine inversion is often difficult due to massive postpartum hemorrhaging. Ultrasonography is useful for the diagnosis in such conditions, but we do not often encounter typical ultrasonographic images in uterine inversion because it occurs rarely. In...
متن کاملAlzheimer's disease: inside, outside, upside down.
Neurotoxicity of beta-amyloid peptide (A beta) in Alzheimer's disease (AD) is usually thought to arise from the nonspecific effects of high concentrations of A beta on vulnerable neurons, resulting in membrane destabilization and increasing intracellular calcium concentration. This review advances the hypothesis that at early stages of AD, when A beta is present in lower amounts, its ability to...
متن کاملRamanujan Series Upside-down
We prove that there is a correspondence between Ramanujan-type formulas for 1/π and formulas for Dirichlet L-values. Our method also allows us to reduce certain values of the Epstein zeta function to rapidly converging hypergeometric functions. The Epstein zeta functions were previously studied by Glasser and Zucker.
متن کاملUpside-down deduction
Over the recent years, several proposals were made to enhance database systems with automated reasoning. In this article we analyze two such enhancements based on meta-interpretation. We consider on the one hand the theorem prover Satchmo, on the other hand the Alexander and Magic Set methods. Although they achieve different goals and are based on distinct reasoning paradigms, Satchmo and the A...
متن کاملCommunity Ecology: Top-Down Turned Upside-Down
Within African savannas, elephants often damage individual trees to the extent that they influence tree density. New research shows that mutualistic ants inhabiting certain species of Acacia protect trees from catastrophic herbivory by elephants. Protection by the ants stabilizes tree cover across savannas in what is otherwise a highly dynamic biome.
