Based on the type of cells or tissues they tend to harbor or attack, many of the viruses are characterized. But, in case of neurotropic viruses, it is not possible to classify them based on their tropism because many of them are not primarily neurotropic. While rabies and poliovirus are considered as strictly neurotropic, other neurotropic viruses involve nervous tissue only secondarily. Since ...

When prescribing intensive care to an unconscious patient, it is important determine the etiological factor of critical condition. The distribution patients by neurotropic or vasotropic mechanism disturbance consciousness extremely for successful treatment and prevention complications. Determination autoantibodies brain tissue diagnostic criterion adequacy care. Administration substances with s...

background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...

Neurophysiology. Nerve growth factor (NGF) is a neurotropic factor essential for the survival and maintenance of NGF-dependent neurons. NGF-dependent neurons include NGF-dependent primary afferents and sympathetic postganglionic neurons in the peripheral nervous system (PNS). NGF-dependent neurons in the PNS form an interface between the nervous system and the body-proper (the organism minus th...

Cell-intrinsic innate immune responses mediated by the transcription factor interferon regulatory factor 3 (IRF-3) are often vital for early pathogen control, and effective responses in neurons may be crucial to prevent the irreversible loss of these critical central nervous system cells after infection with neurotropic pathogens. To investigate this hypothesis, we used targeted molecular and g...

Novel approaches attempt to provide an alternative to autologous nerve graft. Nerve guidance conduit (NGC) have been designed to bridge the gap and provides guidance for sprouting axon and provide a place for diffusion of neurotropic factors and endogenous/transplanted cells at the lesion site [2]. It is believed that an ideal nerve conduit should provide not only structural support for damaged...

PURPOSE To develop, by specific genetic modification, a differentiated human retinal pigment epithelial (RPE) cell line with an extended life span that can be used for investigating their function in vitro and for in vivo transplantation studies. METHODS Primary human RPE cells were genetically modified by transfecting with a plasmid encoding the simian virus (SV)40 large T antigen. After cha...

some lie algebra analogues of schur's theorem and its converses are presented. as a result, it is shown that for a capable lie algebra l we always have dim l=z(l)  2(dim(l2))2. we also give give some examples sup- porting our results.
