Intrahepatic virus-specific CD8(+) T cells are thought to be important for the control of hepatitis C virus (HCV) infection, yet the precise kinetics for the expansion of epitope-specific T cells over the course of infection are difficult to determine with currently available methods. We used a real-time PCR assay to measure the frequency of clonotypic HCV-specific CD8(+) T cells in peripheral ...

The monoclonal antibody termed SN10 (IgG1-k) which was generated and characterized in the present study shows a highly selective reactivity with fresh (uncultured) human leukemia-lymphoma cells. The antigen defined by SN10 is a cell surface glycoprotein composed of a single polypeptide chain of Mr 36,000 and designated as gp36. The primary reactivity of SN10 is against mature B-lineage leukemia...

Pluripotent hemopoietic progenitors (CFU-GEMM) give rise to multilineage hemopoietic colonies in culture. We have examined the erythropoietin requirements of CFU-GEMM-derived erythroid progeny in patients with polycythemia vera (PV) and studied their proliferative activity by short-term exposure to 3HTdR. Mixed colonies with erythroid components were observed in all bone marrow and peripheral b...

the presence of a low level of m protein in the peripheral blood

Background and Objectives: The mesenchymal stem cells derived from peripheral blood (PB) have been recognized as a promising source for allogeneic cell therapy. The aim of this study was to investigate the isolation, growth and differentiation ability of peripheral blood-isolated mesenchymal stem cells. Methods: The mononuclear cells were purified from fr...

We studied 228 consecutive stem cell transplant recipients, screened for reactivation of human herpesvirus-6 (HHV-6) in peripheral blood and other specimens as clinically indicated by means of qualitative polymerase chain reaction. Among them, 197 received an allograft and 31 autograft. Ninety-six of 228 patients (42.1%) showed HHV-6 reactivation in peripheral blood and 129 of 228 (56.6%) demon...

The functions of different regulatory T cell (Treg) types in cancer progression are unclear. Recently, expression of the transcription factor Helios was proposed as a marker for natural (non-induced) Tregs. The present study investigated the clinical significance of Helios expression in patients with non-small cell lung cancer (NSCLC). We enrolled 64 patients with NSCLC, of whom 45 were treated...

Fentanyl is a potent synthetic narcotic analgesic available through the prescription of various formulations; intravenous injection, transmucosal lollipops and lozenges, as well as transdermal patches. Over the years, fentanyl has been a steadily increasing topic of discussion in the literature with pharmacokinetic studies, postmortem case studies, antemortem case studies, comparison of postmor...
