The role of international organisations in controlling invasive species and preserving biodiversity.
Invasive alien species spread through the environment and threaten native biodiversity, assisted by the absence of natural enemies. Alien species may also carry pathogens, which can be transmitted to native species. About half of the known endangered species are under threat from invasive alien species. The Conference of the Parties to the Convention on Biological Diversity in 2008 invited rele...
Hypervelocity collisions with space debris (SD, natural meteoroids and man-made artifacts) can significantly affect the performance of spacecraft. Here, I use an adaptivemesh Eulerian hydrodynamic code, Mie-Grüneisen solid-mechanics, and a simple material-failure model, running on a modern PC, to analyze the protection afforded by a nominal two-plate aluminum shield to hypervelocity collisions ...
About 40 years ago, invasive prenatal diagnosis techniques were introduced in obstetrics. Initially, amniocentesis was performed followed by placentacentesis, fetoscopy, fetal blood sampling (FBS), and chorionic villus sampling (CVS). These procedures, while invading the uterine environment, have made it possible to proceed with the retrieval of biological tissue of fetal origin for analysis an...

Invasive aspergillosis (IA) is one of the most common life-threatening complications in immunocompromised patients. Voriconazole is currently the drug of choice for IA treatment. However, some patients with IA suffer clinical deterioration despite voriconazole therapy. Management of voriconazole-refractory IA remains challenging; no useful recommendations have yet been made. Voriconazole-refrac...
Distinction between non-invasive and invasive thymomas is almost impossible by histologic examination alone, because the morphology of invasive thymoma does not significantly differ from that of non-invasive thymoma [1,2]. However, tumor invasiveness is regarded as the most important factor affecting survival in thymoma [3]. In the present study, we examined the expression of some cancer-relate...
