To investigate the molecular deficiency in MMR genes associated to Lynch syndrome.

Migration causes temporal and energetic constraints during plumage development, which can compromise feather structure and function. In turn, given the importance of a good quality of flight feathers in migratory movements, selection may have favoured the synthesis of feathers with better mechanical properties than expected from a feather production constrained by migration necessities. However, n

Three novel tetracyclic terpenoids, of which two possess potent cytotoxic activities towards various mammalian cell lines, were isolated front extracts of the fermentation broth of the ascomycete Dasayscyphus niveus. The structures of the compounds, named dasyscyphins A-C, were determined with spectroscopic techniques. (c) 2005 Elsevier Ltd. All rights reserved.

We present some results on the existence of bounded positive solutions to a class of nonlinear second order ordinary diferential equations by using the Schauder-Ekhonov fixed point theorem. An application to the existence of bounded positive solutions to certain quasilinear elliptic equations in two-dimensional exterior domains is also given.

A rare fossiliferous site in Willacy County, Texas, contains a mass concentration of fossil Giant Gopher Tortoises (Gopherus hexagonatus). The site southeast of Raymondville was exposed in the late 1980s during archaeological surveys for drainage canal improvements. Numerous large adults with complete shells were recovered along with partial limb, cranial, and vertebral elements. Especially remark

The dolphin-like ichthyosaurs – also known as ‘fish lizards’ – are extinct marine reptiles that roamed the Mesozoic oceans for some 160 million years. As for most ancient vertebrates, our knowledge of these iconic animals largely derives from biomineralized hard parts (teeth and bones). However, soft tissues are also known from a number of Lagerstätte specimens, and have opened up new avenues for

In many application domains, critical systems must comply with safety standards. This involves gathering safety evidence in the form of artefacts such as safety analyses, system specifications, and testing results. These artefacts can evolve during a system's lifecycle, creating a need for impact analysis to guarantee that system safety and compliance are not jeopardised. Although extensive resear

Världen över ställs stater inför ett växande cyberhot och antalet mellanstatliga cyberoperationer har ökat markant. Idag är inte enbart datorer och mobiltelefoner beroende av en uppkoppling utan även transaktioner, pacemakers, bilar, flygplan och otaliga tillbehör i vår vardag. Därutöver styrs en stor del av samhällets infrastruktur såsom sjukhus, banker och energisektorn av särskilda informationsAround the world states are facing a growing cyber threat and the number of intergovernmental cyberoperations is significantly increased. Today, not only computers and mobile phones are dependent on a connection, even transactions, pacemakers, cars, airplanes and innumerable accessories in our daily lives depend upon it. Furthermore, a considerable part of society’s infrastructure, like hospitals,

In this paper we call into question the relationship between development, inequality and territory in the current context of globalization and within the framework of public policies designed, supposedly, to benefit those social actors with fewer resources. In order to do this, we focus on a case study in the northeast of the province of Misiones, Argentina. Here tobacco production, forestry and a
