[Desmoplastic tumors with multiple differentiation. A new entity. Six cases]. Desmoplastic tumours with divergent differentiation are principally located in the abdomen and develop locally or regionally. They occur in adolescents or young adults and are characterized at histology by a proliferation of undifferentiated small cells surrounded by a dense stroma. Only immuno–histo–chemistry provides the diagnosis. Since their chemosensitivity …

Nanoplasmonic quantitative detection of intact viruses from unprocessed whole blood. Infectious diseases such as HIV and hepatitis B pose an omnipresent threat to global health. Reliable, fast, accurate, and sensitive platforms that can be deployed at the point-of-care (POC) in multiple settings, such as airports and offices, for detection of infectious pathogens are essential for …

Complex impedance spectroscopy for monitoring tissue responses to inserted neural implants. A series of animal experiments was conducted to characterize changes in the complex impedance of chronically implanted electrodes in neural tissue. Consistent trends in impedance changes were observed across all animals, characterized as a general increase in the measured impedance magnitude at 1 kHz. …

Isolation, characterization and investigation of differentiation potential of human periodontal ligament cells and dental follicle progenitor cells and their response to BMP-7 in vitro. The aim of this study was to assess the factors, mechanisms and the differences between periodontal ligament (PDL) cells and denta l follicle (DF) progenitor cells towards the osteoblastic/cementoblastic differentiation and …
