Aquatic invasive alien rodents in Western France: Where do we stand today after decades of control?

Two aquatic invasive alien rodents, the coypu (Myocastor coypus) and muskrat (Ondatra zibethicus), have taken over a significant amount of wetlands in France. Pays de la Loire is an administrative region of about 32 000 km2 in the Western France with 6.3% of its area in wetlands (excluding the Loire River).

Behavioral changes in preterm children during nasogastric tube feeding. Comparative study of manual administration by parents versus mechanical administration via electric syringe pump.

Introduction: Manual feeding by parents using a syringe, a widespread practice in Sweden since the 1980s, favors parents' involvement in childcare tasks. This approach is used in our neonatal unity since 2007.

Objective: To study the behavioral changes of preterm children during nasogastric tube feeding: manual milk administration by parents (MAP) versus electric syringe administration (ESA) over a 30-minute period.

Image analysis software for automatic DNA ploidy assessment of archival solid tumours.

Background: Image cytometry has proved to provide a good alternative to flow cytometry for DNA ploidy measurement of archival tumors. However, when interactively done this technique is unable to give statistically valuable results within an acceptable time for clinical oncology.

Methods: An image cytometer was developed for fully automatic DNA ploidy quantitation, focusing efforts on speed and accuracy.

[Neighborhood graphs and image processing. Contribution to images of immunohistochemical staining].

Devising an image analyzer dedicated to the automatic quantification of immunohistochemical staining for clinical oncology implies developing a method for the delimitation of tumoral cell nests, setting aside tumoral stroma, while accounting for the topology of the staining. The representation of images by neighborhood graphs can bring an answer to both requirements. In this paper, a methodological approach is presented.
