The plasticity of dental pulp stem cells (DPSCs) has been demonstrated by several studies showing that they appear to self-maintain through several passages, giving rise to a variety of cells. The aim of the present study was to differentiate DPSCs to mature neuronal cells showing functional evidence of voltage gated ion channel activities in vitro. First,(More)
The effects of KCl-treatment on the survival and proliferation of NE-4C self-renewing neural progenitor cells were investigated during early phases of in vitro induced neurogenesis. NE-4C cells, derived from the anterior brain vesicles of embryonic mouse (E9), divided continuously under non-inducing conditions, but acquired neuronal features within 6 days,(More)
The effects of GYKI 52466, a new 2,3-benzodiazepine with muscle relaxant and anticonvulsant properties, were investigated and compared to those of midazolam in electrophysiological experiments. The effects of the drugs on the reflex potentials evoked by afferent nerve stimulation and recorded from the spinal roots in unanesthetized spinal cats were studied.(More)
The inflammatory response associated with Staphylococcus aureus osteomyelitis results in extensive bone damage characterized by apparent increases in bone resorption and formation. These results suggest an increased local release of agents capable of modulating bone remodelling. Tumor necrosis factor alpha (TNF-alpha) is a proinflammatory cytokine proposed(More)
NE-4C, a p53-deficient, immortalized neuroectodermal progenitor cell line, was used to investigate the role and importance of cellular interactions in neural commitment and differentiation. NE-4C cells give rise to neurons and astrocytes in the presence of all-trans retinoic acid, if they can establish intercellular contacts. Aggregation per se, however,(More)
This paper reviews the recent data on the role of vitamin D (VD) in the genesis of various immunological disorders. It inhibits immune reactions in general, but it enhances the transcription of 'endogenous antibiotics' such as cathelicidin and defensins. VD inhibits the genesis of both Th1- and Th2-cell mediated diseases. The pleiotropic character(More)
The extracellular pH, sodium and divalent cation concentrations influence the ATP-induced changes in cytosolic Ca(2+) concentration ([Ca(2+)](i)). This elevation of [Ca(2+)](i) and activation of Ca(2+)-dependent Cl(-) channels represent a possible therapeutic approach in cystic fibrosis (CF). We investigated the changes of [Ca(2+)](i) in different external(More)
In the present study, the pharmacological effects of etiprednol dicloacetate (BNP-166; ethyl-17alpha-dichloroacetoxy-11beta-hydroxyandrosta-1,4-diene-3-one-17beta-carboxylate), a new soft steroid, intended to use for the treatment of asthma, were investigated in an animal model of allergen sensitized and challenged Brown Norway rats using local treatment.(More)
In the first part of this series of papers (Székely and Pataki, 102) the pathogenesis of asthma was approached as a pathological antigen-antibody complex induced vago-vagal axon reflex. In the next part (103) the contribution of individual hormonal predisposition, the environmental and the most frequent allergizing factors have been reviewed. In the first(More)
