A 35 month old girl had suffered from painful joint contractures of the whole body since a few months after birth, and she gradually developed numerous periarticular and subcutaneous nodules, hoarseness, swallowing difficulty with recurrent respiratory infections, nystagmus, and mental and developmental retardation. She was misdiagnosed as having juvenile rheumatoid arthritis at several univers...

Foamy viruses are retroviruses of the spumavirus family that are often isolated from primary cultures of primate cells. We previously constructed vectors based on human foamy virus (HFV) and found that they were able to transduce a wide variety of vertebrate cells by integration of the vector genome. Here we show that several types of hematopoietic cells are efficiently transduced by an HFV vec...

Xanthogranulomatous inflammation is a form of chronic inflammatory process with collection foamy macrophages in sheets, often presence giant cell reaction. Here, we present case xanthogranulomatous osteomyelitis tibia 43 years old patient, which rare pathological entity and possibly was reported first 1984. The histopathological sections revealed dense lympho-plasmacytic infiltrate the marrow s...

Chimpanzee (Pan troglodytes) agonistic screams are graded vocal signals that are produced in a context-specific manner. Screams given by aggressors and victims can be discriminated based on their acoustic structure but the mechanisms of listener comprehension of these calls are currently unknown. In this study, we show that chimpanzees extract social information from these vocal signals that, c...

Human foamy virus can establish persistent infections in human hematopoietic cell lines, such as H92.1.7 (erythroblastoid cells), Jurkat (CD4+ T cells), and U937 (myeloid-monocytic cells). The infection is characterized by constant production of infectious viruses (for > 2 1/2 years) with no cytopathic effects on the host cells. Electron microscopy of the infected cells showed a viral morpholog...

Foam-based materials are promising micro-structured materials with interesting thermal and acoustical properties. The control of the material morphology requires counteracting all the destabilizing mechanisms during their production, starting with the drainage process, which remains to be understood in the case of the complex fluids that are commonly used to be foamed. Here we perform measureme...
