INTRODUCTION The authors present recent results in the Hungarian hantavirus ecology and epidemiology. Most of the research was done between 1992-2000. AIM To determine the presence and geographic distribution of hantaviruses and to get more detailed information of human and small-mammal infection with these viruses in Hungary. METHODS For diagnostic(More)
The majority of the viral hepatitis cases is caused by five hepatitis viruses (A,B,C,D,E). In 1997, TT virus was discovered. It was supposed that a number of the unknown hepatitis cases was caused by the TT virus. The aim of this study was to characterize TT viruses carried by healthy individuals and patients suffering from hepatitis of unknown origin in(More)
We examined the diversity of HIV-1 subtypes in 11 adults from Hungary, using the heteroduplex mobility assay (HMA) and DNA sequencing. HMA results showed that HIV-1 gp120 sequences from 10 patients were of subtype B, whereas 1 patient, infected in Africa, carried a subtype C strain. DNA sequencing confirmed the HMA results and revealed a high intrasubtype(More)
The aim of this study was to investigate the genetic diversity of HIV-1 strains circulating in Slovenia. Proviral DNA isolated from peripheral blood mononuclear cells (PBMCs) of 20 randomly selected HIV-1-infected individuals was classified into subtypes by sequence-based phylogenetic analysis of the env (C2V3) and gag (p24) regions of the viral genome. The(More)
The lentiviral protein Nef recruits cellular signalling proteins to lipid rafts at the cell membrane and acts thereby as a master regulator affecting the transcription of a series of cellular genes. By activating resting T cells, Nef creates an optimal environment for lentivirus replication. In human immunodeficiency virus (HIV) infected macrophages and(More)
Since methylcytosine is relatively unstable, a deficiency of CpG dinucleotides and accumulation of mutations that manifest as TpG (and its complement CpA) is a diagnostic feature of higher eukaryotic DNA sequences subjected to methylation by DNA (cytosine-5) methyltransferases. Latent viral genomes may also be affected by DNA methylation in their host(More)

During the last two decades there has been a resurgence of arguments against physicalism and for varieties of metaphysical dualism. The conclusion of these arguments is that phenomenal consciousness is absent from a world that is purely physical. Many contemporary philosophers of mind have found some of these arguments to be persuasive and have opted for(More)
Proponents of non-conceptual content have recruited it for various philosophical jobs. Some epistemologists have suggested that it may play the role of “the given” that Sellars is supposed to have exorcised from philosophy. Some philosophers of mind (e.g., Dretske) have suggested that it plays an important role in the project of naturalizing semantics as a(More)
HIV-1 was isolated from a child at 6 and 9 months of age, proving the vertical transmission of infection from the mother with AIDS. The p24 antigen test of the plasma at 9 months of age was positive as well. A positive PCR reaction was detected in J34 cells, infected with the supernatant of the peripheral blood lymphocytes of the child. According to(More)
