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 …

[Low grade fibromixoid sarcoma: a purpose of 3 cases and review of the bibliography]. BACKGROUND Low grade fibromyxoid sarcoma or tumor Evans is a variety of soft tissue sarcoma that represents 1% of all malignancies. More common in limbs and trunk (50%), we present 3 new cases of retroperitoneal reviewing their characteristics and performing a …
