Neuronal death and vacuolation are characteristics of the CNS degeneration found in prion diseases. Relatively few cultured cell lines have been identified that can be persistently infected with scrapie prions, and none of these cells show cytopathologic changes reminiscent of prion neuropathology. The differentiated neuronal cell line GT1, established from gonadotropin hormone releasing-hormon...

Swinepox virus was successfully adapted to the PK-15 cell line, but not the MDBK cell line. Virus titers obtained in the PK-15 host cell system were comparable to diploid swine kidney cell cultures.

this article reviews will focus on the concept and formation of micro particles (mps) in circulation and their role in transfusion medicine and immune system. mps are cell membrane derived vesicles which express markers of their parent cells and are found in circulation at low levels. exact functions of mps are unclear. in here, physiological almost all types of circulating mps including platel...

PURPOSE Although all contact lenses (CLs) are applied initially to the eye directly from a packaging solution, little is known about the effects of these solutions on human corneal epithelial cells (HCECs). Due to the porous nature of CL materials, they have the potential to sorb components of the packaging solution during storage, which could then be subsequently released upon insertion of the...

Introduction: Previous studies have shown that the ultra-high molecular weight polyethylene (UHMWPE) used in total disc replacement (TDR) will oxidize during shelf storage and following implantation1 for components gamma sterilized in air and in first-generation barrier packaging. Specifically, the areas that readily have access to bodily fluids and tissues (i.e. the rim of the Charité TDR) oxi...

Neuropeptide Y (NPY) is a 36 amino acid peptide found throughout the central and peripheral nervoussystem of rat and human. NPY has been proposed to play an important role in satiety. The aim of this studywas to produce cell lines that secrete high levels of bioactive NPY. For this purpose, the complementaryDNA (cDNA) that encodes NPY was isolated by PCR. The cDNA was then clo...
