Repeated Quaternary glaciations have significantly shaped the present distribution and diversity of several European species in aquatic and terrestrial habitats. To study the phylogeography of freshwater invertebrates, patterns of intraspecific variation have been examined primarily using mitochondrial DNA markers that may yield results unrepresentative of the true species history. Here, popula...

From 1977 (index case) to 2006, 87 cases of visceral leishmaniasis were confirmed in the municipality of Rio de Janeiro, Brazil, in periurban areas on the continental and coastal slopes of the Pedra Branca massif and the continental slopes of the Gericinó massif. The majority (65.5%) of the patients were more than five years old, predominantly males (61.5%), but without any difference between t...

Geological similarity between Hercynian zones from Brittany and the Iberian Peninsula has led various authors [l-31 to propose that these zones were once continuous. Bard et ai. [3], for example, reconstmct the Hercynian 1bero.Armorican belt to find the position of the Iberian peninsula before the opening of the Bay of Biscay (1 50 to 200 my ago). They assume continuity of Hercynian structures ...

The Garonne is the largest river in the south-west of France, and its drainage basin stretches between the Pyrénées and the Massif Central mountains. Until now, no water stable isotope study has been performed on the whole Garonne river basin which is composed of different geological substrata, and where the water resources are limited during the dry summer period. This study focuses on the Gar...

Considerable effort is dedicated to evaluating macromolecular crystals at synchrotron sources, even for well established and robust systems. Much of this work is repetitive, and the time spent could be better invested in the interpretation of the results. In order to decrease the need for manual intervention in the most repetitive steps of structural biology projects, initial screening and data...

Purpose. To perform a critical analysis of approaches to determining the stress-strain state "horizontal working – layered massif" system. Obtain informed decisions for applying specific approach case massif. substantiate metric finite element models system massif". Methodology. achieve purpose, peculiarities rock were analyzed. It has been proven that layering is most important structural feat...

PATIENTS Seventeen ambulatory adult males with wellestablished diagnoses of chronic ulcerative colitis were studied. Rectal biopsies were compatible in each case. Patients were chosen who were in clinical remission, and without friable or ulcerating mucosa at the time of the investigation. Fifteen patients had been taking salicylazosulphapyridine (Azulfidine) for six to 24 months. None had been...

We derive new, very precise estimates for averages of arithmetic functions over friable integers from analytic information on their associated Dirichlet series. These yield significant improvements upon available results in classical cases, in particular concerning the effective expansion of “abstract” main terms of de Bruijn type. These results also permit new applications, linked to the solub...

Urinary bladder rhabdomyosarcoma from a 9-month-old female Labrador retriever dog is described. Grossly reddish black multiple friable multinodular masses filled the lumen of the urinary bladder. Histologically, the masses consisted of round, fusiform and polygonal cells with various consistencies. There were also some strap-like cells with chained nuclei and cross-striations. It was diagnosed ...

Xanthogranulomatous inflammation (XGI) is a rare phenomenon and can involve any organ system. The involvement of colon is rarely described in the literature. We herein report a case of XGI in a 60 year-old male who presented with friable ulceroinfiltrative mass in colon. Right hemicolectomy was performed with clinical and radiological suspicion of malignancy. This is the first reported case of ...
