In the present study, we demonstrate that the terminal inverted repeats of the Escherichia coli insertion sequence IS30 are functional target sites for the transposition of the (IS30)2 dimer, which represents an intermediate structure in the transposition of IS30. Comparative analysis of various target regions revealed that the left and right ends differ in their "attractivity." In our experiments, the joined left and right ends, i.e., the (IS30)2 intermediate structure, was found to be the most preferred ...

Gill necrosis is a widespread disease of common carp in Europe. Much effort has been concentrated in the investigation of its aetiology during the last 15 years. The results of a three-year research project are presented here and the role of bacteria is demonstrated. This paper shows the development of the disease and the relationship between environmental stress and bacterial invasion. Both healthy and diseased carp populations were monitored for the presence of Flexibacter columnaris. Gill necrosis ...

A similarity-search system is described for proton-NMR spectroscopy. In order to achieve fast retrieval of reference compounds, the 1H-NMR spectra of the data base and of the unknown are encoded in a bitsring. The individual bits of the binary signature describe different features of the spectra. Part of the coupling information is coded in such a way that effects of magnetic field strength are taken into account. The encoding thus permits a fast search for identical and structurally similar reference ...

A female, adult ornate box turtle (Terrapene ornata ornata) with fatty liver was submitted for virologic examination in Hungary. Signs of an adenovirus infection including degeneration of the liver cells, enlarged nuclei and intranuclear inclusion bodies were detected by light microscopic examination. The presence of an adenovirus was later confirmed by obtaining partial sequence data from the adenoviral DNA-dependent DNA-polymerase. Phylogenetic analyses revealed that this novel chelonian adenovirus ...

High-order harmonic generation by few-cycle 800 nm laser pulses in neon gas in the presence of a strong terahertz (THz) field is investigated numerically with propagation effects taken into account. Our calculations show that the combination of THz fields with up to 12 fs laser pulses can be an effective gating technique to generate single attosecond pulses. We show that in the presence of the strong THz field only a single attosecond burst can be phase matched, whereas radiation emitted during other ...

Malignant melanoma represents the third common cause of brain metastasis, having the highest propensity to metastasize to the brain of all primary neoplasms in adults. Since the central nervous system lacks a lymphatic system, the only possibility for melanoma cells to reach the brain is via the blood stream and the blood-brain barrier. Despite the great clinical importance, mechanisms of transmigration of melanoma cells through the blood-brain barrier are incompletely understood. In order to investigate ...

Recently described forkhead box protein 3 (FoxP3) transcription factor is a key molecule in CD4+ CD25hi+ T-cell characterization. Invariant NK T (iNKT) cells are also characterized as regulatory cells modulating the immune response by rapidly producing T(h)1 and T(h)2 cytokines. We aimed to analyze cellular markers important in regulatory features of human iNKT cells and to study their role in functional assays. iNKT cells were single cell sorted from peripheral mononuclear cells of healthy individuals ...

Abstract Unilateral facial nerve transection induces plastic reorganization of the somatotopic order in the primary motor cortex area (MI). This process is biphasic and starts with a transient disinhibition of connections between cortical areas in both hemispheres. Little is known about the underlying mechanisms. Here, cortical excitability has been studied by paired pulse electrical stimulation, applied either within the MI or peripherally to the trigeminal nerve, while the responses were recorded ...

A rapid cyanobacterial bloom of Cylindrospermopsis raciborskii (3.2 × 104 filaments/mL) was detected early November, 2012, in the Fancsika pond (East Hungary). The strong discoloration of water was accompanied by a substantial fish mortality (even dead cats were seen on the site), raising the possibility of some toxic metabolites in the water produced by the bloom-forming cyanobacteria (C. raciborskii). The potential neuronal targets of the toxic substances in the bloom sample were studied on identified ...

The characterization of microcline in the particle size ranges of 1−71 μm and 71−315 μm gained by sieving was proved using X-ray diffraction (XRD) and scanning electron microscopy combined with energy-dispersive detector (SEM-EDS) in powder form, over laser diffraction measurements in aqueous suspension. The optimum dosage of adsorbent was 13.5 g/L in ...

Abstract Graphene oxide (GO) is not only an intermediate in top-down graphene preparation, but it is also acknowledged for its convenient application when the hydrophobicity of graphene is a drawback. Its preparation through the wet exfoliation of graphite inevitably leads to a product lacking several of the outstanding features of graphene. The destroyed graphene structure can be at least partially reconstructed by thermal and/or wet chemical reduction. Thermally reduced graphene oxide (TRGO) was ...

Solvent-free radiofrequency (RF) nitrogen plasma treatment was applied to incorporate nitrogen atoms in relatively high concentration. Graphene oxide (GO) and two reduced GOs of different O-content were used as target substrates to reveal the influence of the functional groups decorating the graphene lattice on the quantity and quality of nitrogen incorporation. Despite the relatively high oxygen content of the samples no N–O bonds develop but three kinds of different N–C bonds of very similar concentration ...

SEA0400 is a recently developed inhibitor of the Na+/Ca2+ exchanger (NCX) shown to suppress both forward and reverse mode operation of NCX. Present experiments were designed to study the effect of partial blockade of NCX on Ca handling and contractility in Langendorff-perfused guinea pig hearts loaded with the fluorescent Ca-sensitive dye fura-2. Left ventricular pressure and intracellular calcium concentration ([Ca2+]i) were synchronously recorded before and after cumulative superfusion with 0.3 and ...

We constructed an in vivo system to detect transpositional rearrangements induced by the insertion sequence IS30. The transposase protein expressed from the transposase producer plasmids catalyzed rearrangements on different target sequences presented in trans. High yields, up to 83%, of transpositional frequencies were observed. The frequency of rearrangements correlated with the amount of transposase protein produced and the attractivity of the target sequences. Alteration in the frequency of ...

The kinetics of garnet formation by solid state reactions were reinvestigated by sintering the mixtures of Y2O3 and Fe2O3 powders at several temperatures from 800 to 1400°C for 3–12 h in air. Among the reaction products of mixtures sintered at 800–1300°C YFeO3 was always found by X-ray diffraction methods. The temperature region of orthoferrite stability depends on the grain size of the starting materials. According to SEM and electron probe microanalysis investigations, the reaction is controlled ...

This article provides an overview of IEEE 802.1aq shortest path bridging and outlines some application scenarios that will benefit from the new capabilities SPB offers. SPB is built on the IEEE 802.1 standards, and inherits unaltered the existing OAM and data plane scalability enhancements, such as the MAC-in-MAC forwarding paradigm. SPB introduces link state control for bridge networks, thus improving control plane scalability, network bandwidth utilization, and control of the forwarding paths. ...
