Transplantation of bone marrow mesenchymal stem cells (MSCs) promotes functional recovery in multiple sclerosis (MS) patients and in a murine model of MS. However, there is only a modicum of information on differentiation of grafted MSCs into oligodendrocyte-like cells in MS. The purpose of this study was to transplant neurotrophin-3 (NT-3) and retinoic(More)
Severe spinal cord injury often causes temporary or permanent damages in strength, sensation, or autonomic functions below the site of the injury. So far, there is still no effective treatment for spinal cord injury. Mesenchymal stem cells (MSCs) have been used to repair injured spinal cord as an effective strategy. However, the low neural differentiation(More)
Cholera toxin B subunit (CTB) has been extensively used in the past for monosynaptic mapping. For decades, it was thought to lack the ability of transneuronal tracing. In order to investigate whether biotin conjugates of CTB (b-CTB) would pass through transneurons in the rat spinal cord, it was injected into the crushed left sciatic nerve. For experimental(More)
In glass bottle inspection, the defects detection is of first importance. For online system detection, high speed and robust detection of faults are highly required. Neural networks have recently, and successfully, been applied to fault detection in many manufacturing processes. In this study, a Gaussian neural network, an extension of the RBF network,(More)
Human immunodeficiency virus (HIV) IIIB expression and Epstein-Barr virus (EBV) B95.8-induced transformation were studied during coinfection. Coinfection of peripheral blood lymphocyte (PBL) cultures with HIV and EBV resulted in down-regulation of HIV expression. EBV-induced and spontaneous transformation were markedly reduced in PBL cultures exposed to HIV(More)
The production of the dihydrofolate reductase-thymidylate synthase (DHFR-TS) bifunctional protein of Plasmodium falciparum was measured in the wild type, pyrimethamine sensitive strain, FCR3, and in a pyrimethamine resistant mutant, FCR3-D7, which contains a DHFR-TS gene duplication that overproduces a mutant enzyme. The DHFR-TS content in both strains(More)
CR2 (CD21), the EBV receptor, was detected on three of four CD4-positive cell lines by indirect fluorescent labeling, and its corresponding mRNA was found by use of the reverse transcription-based polymerase chain reaction. To determine whether CR2 on CD4-positive cells was functional, their ability to be infected by EBV was analyzed. EBV DNA, EBV nuclear(More)
CD4+ and CD8+ T lymphocytes purified from normal adult donors by flow cytometry could be infected with Epstein-Barr virus (EBV) as measured by the accumulation of components of the EBV replicative cycle, viral DNA and viral transcripts encoding EBER1 and BRLF1. EBV infection resulted in enhanced replication of human immunodeficiency virus type 1 (HIV-1)(More)
