Abstract
On 27 December 2004, a giant gamma flare from the Soft Gamma-Ray Repeater 1806-20 saturated many satellite gamma-ray detectors, being the brightest transient event ever observed in the Galaxy. AMANDA-II was used to search for down-going muons indicative of high-energy gammas and/or neutrinos from this object. The data revealed no significant signal, so upper limits (at 90% C.L.) on the normalization constant were set: 0.05(0.5) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the gamma flux and 0.4(6.1) TeV-1 m;{-2} s;{-1} for gamma=-1.47 (-2) in the high-energy neutrino flux.

Abstract
We demonstrate optical tuning of the scattering length in a Bose-Einstein condensate as predicted by Fedichev et al. [Phys. Rev. Lett. 77, 2913 (1996)]. In our experiment, atoms in a 87Rb condensate are exposed to laser light which is tuned close to the transition frequency to an excited molecular state. By controlling the power and detuning of the laser beam we can change the atomic scattering length over a wide range. In view of laser-driven atomic losses, we use Bragg spectroscopy as a fast method to measure the scattering length of the atoms.

Abstract
We present the results of a search for point sources of high-energy neutrinos in the northern hemisphere using AMANDA-II data collected in the year 2000. Included are flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic-ray-induced atmospheric neutrinos and misreconstructed downgoing cosmic-ray muons reveals no statistically significant neutrino point sources. We show that AMANDA-II has achieved the sensitivity required to probe known TeV gamma-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and gamma-ray fluxes are equal.

Abstract
Data from the AMANDA-B10 detector taken during the austral winter of 1997 have been searched for a diffuse flux of high energy extraterrestrial muon neutrinos. This search yielded no excess events above those expected from background atmospheric neutrinos, leading to upper limits on the extraterrestrial neutrino flux measured at the earth. For an assumed E-2 spectrum, a 90% classical confidence level upper limit has been placed at a level E2Phi(E)=8.4 x 10(-7) cm(-2) s(-1) sr(-1) GeV (for a predominant neutrino energy range 6-1000 TeV), which is the most restrictive bound placed by any neutrino detector. Some specific predicted model spectra are excluded. Interpreting these limits in terms of the flux from a cosmological distributions of sources requires the incorporation of neutrino oscillations, typically weakening the limits by a factor of 2.

Abstract
Neutrinos are elementary particles that carry no electric charge and have little mass. As they interact only weakly with other particles, they can penetrate enormous amounts of matter, and therefore have the potential to directly convey astrophysical information from the edge of the Universe and from deep inside the most cataclysmic high-energy regions. The neutrino's great penetrating power, however, also makes this particle difficult to detect. Underground detectors have observed low-energy neutrinos from the Sun and a nearby supernova, as well as neutrinos generated in the Earth's atmosphere. But the very low fluxes of high-energy neutrinos from cosmic sources can be observed only by much larger, expandable detectors in, for example, deep water or ice. Here we report the detection of upwardly propagating atmospheric neutrinos by the ice-based Antarctic muon and neutrino detector array (AMANDA). These results establish a technology with which to build a kilometre-scale neutrino observatory necessary for astrophysical observations.

Abstract
BACKGROUND Soluble interleukin 4 receptors (sIL-4R) are present in biological fluids. In contrast to mice, in man no distinct mRNA coding for sIL-4R has been described, suggesting that human sIL-4R is exclusively produced by proteolytic cleavage of the cell surface receptor. It is not known whether human sIL-4R is actively produced during an immune response. METHODS Human purified T cells, CD4+, CD8+, CD45RA+ and CD45R0+ T cell subpopulations were activated in vitro. sIL-4R was determined in the supernatants, cell surface IL-4R was measured by flow cytometry and RT-PCR. RESULTS Recombinant sIL-4R inhibited IL-4-mediated proliferation and IL-5 upregulation by T cells. sIL-4R could be detected at low levels in supernatants of nonactivated T cells, but at high levels following TCR engagement. This response was paralleled by enhanced transcription and de novo synthesis of the human cell surface IL-4R. Both, activated naive CD45RA+ and memory CD45R0+ T cells, produced sIL-4R with long-lasting kinetics. IL-4 increased sIL-4R production by activated CD45RA+, but there was less of an increase by CD45R0+ T cells. In addition, interferon-gamma enhanced sIL-4R production. Cycloheximide and dexamethasone inhibited sIL-4R production by activated T cells, but did not abolish constitutive release of sIL-4R. Phosphoramidon and 1,10-phenanthroline dose-dependently inhibited shedding of the IL-4R, even in nonactivated T cells. CONCLUSION The production of human sIL-4R by T cells is regulated by TCR stimuli, IL-4 and IFN-gamma and needs the activity of metalloproteinases. Thus, sIL-4R should be regarded as inducible and due to its IL-4-antagonizing activity an immunoregulatory molecule.

Abstract
Alpha-subunits of the voltage-gated potassium channel (Kv) subfamily Kv9 show no channel activity after homomultimeric expression in heterologous expression systems. This report shows that heteromultimeric expression of rKv9.1 and rKv9.3 specifically suppresses the currents mediated by alpha-subunits of the Kv2 and Kv3 subfamilies but does not affect currents mediated by alpha-subunits of the Kv1 and Kv4 subfamilies. To understand the molecular basis of the electrical silence of Kv9 homomultimeric channels, crucial functional domains (amino and carboxy terminus, S4 segment, and pore region) were exchanged between Kv9 alpha-subunits and rKv1.3. Electrophysiological studies of these chimeras revealed that the pore region is involved in determining the nonconductive behavior of homomultimeric Kv9 channels. This analysis was extended by protein interaction assays, aiming to identify the region of Kv9 subunits responsible for the specific suppression of rKv2.1- and rKv3.4-mediated currents. We could show that the amino-terminal domain of Kv9 alpha-subunits does not support homomultimeric assembly but interacts specifically with the rKv2.1 amino-terminal region. Conversely, the specific intersubfamily assembly of rKv3.4 with rKv9.1 or rKv9.3 is governed by the hydrophobic core and not the amino-terminal domain.

Abstract
OBJECTIVES To investigate whether DNA damage increased in subjects possibly exposed to high amounts of antineoplastic agents. METHODS The level of genetic damage was determined in peripheral mononuclear blood cells with the sister chromatid exchange test, the alkaline elution technique, and the cytokinesis block micronucleus test. RESULTS The supposed increased exposure of the study subjects was caused by a malfunction of a safety hood resulting in leakage of air during preparation of an infusion of an antineoplastic drug. Two months after a new safety hood was installed, the frequencies of micronuclei and sister chromatid exchanges of exposed nurses (n = 10) were still significantly increased when compared with a matched control group (p < 0.01 and p < 0.05, one sided Wilcoxon test, respectively). In a second examination seven months later, the frequency of micronuclei had significantly decreased to control values (p < 0.05, one sided Wilcoxon test, n = 6). Moreover, the study subjects who smoked (n = 8) had significantly increased frequencies of micronuclei and sister chromatid exchanges (p < 0.01 and p < 0.05, one sided U test, respectively). No differences in the rate of DNA damage could be detected with the alkaline elution technique. CONCLUSIONS Control measures on the level of biological effect should be performed regularly to ensure maximum safety precautions for workers potentially exposed to genotoxic agents.

Abstract
A specific polyclonal antiserum was prepared against a gel-purified 60 kDa extracellular protein of Listeria monocytogenes ATCC 19111 corresponding to protein p60 previously detected in culture broths of L. monocytogenes strains Mackaness and EGD [Kuhn, M. & Goebel, W. (1989), Infection and Immunity 57, 55-61]. Indirect immunogold labelling combined with transmission electron microscopy and high-resolution scanning electron microscopy were used to investigate the location and distribution of p60 on the bacterial cell surface. In bacteria grown to the early stationary phase about 25% of the extracellular protein was estimated to be associated with the cell surface. The anti-p60 antiserum proved to be Listeria-specific. In an indirect immunofluorescence test the antiserum reacted with Listeria strains representing all species and different serotypes, except L. seeligeri, L. welshimeri, L. grayi and L. murrayi. No immunological cross-reactions were observed with 27 strains of bacteria from 16 other genera. The value of the anti-p60 antiserum in developing a diagnostic assay for Listeria cells in environmental samples and foods is discussed.

Abstract
Synthetic sewage containing phenol, acetone, and alkanols plus 4-chlorophenol or a mixture of isomeric chlorophenols is completely degraded by a defined mixed culture with Pseudomonas sp. strain B13 as a chlorocatechol-dissimilating member of the community. Total degradation of the organic carbon was indicated by release of stoichiometric amounts of chloride and low content of dissolved organic carbon in the cell-free effluents. During adaptation to high loads of chlorophenols the initial meta-cleavage activity was completely replaced by ortho-cleavage activity of type I and II. In the fully acclimated culture, hybrid strains such as Alcaligenes sp. strain A7-2 were detected, which are more competitive than Pseudomonas sp. strain B13 with respect to chlorophenol degradation.

Abstract
Naphthalenesulfonate-degrading bacteria were obtained by continuous enrichment from a naphthalene-degrading population from sewage. In addition to naphthalene,
Pseudomonas
sp. A3 can utilize 2-naphthalenesulfonate (2NS) and
Pseudomonas
sp. C22 can utilize both 1-naphthalenesulfonate (1NS) and 2NS as sole carbon sources. In a mixture of 1NS and 2NS, the former substrate is utilized by strain C22 only after complete consumption of 2NS. During exponential growth, approximately 10% of the organic carbon of naphthalenesulfonates is temporarily excreted. These unidentified metabolites can readily be used by other bacteria, which, by supplying strain C22 with vitamins, allow optimal growth in stable mixed cultures. The degradative capability of
Pseudomonas
sp. A3 for 2NS was irreversibly lost under nonselective growth conditions and could be transferred from the wild type to a distinguishable cured strain of the wild type.

Abstract
3-Chlorobenzoate-grown cells of
Pseudomonas
sp. B13 readily cometabolized monofluorobenzoates. A catabolic pathway for the isomeric fluorobenzoates is proposed on the basis of key metabolites isolated. Only 4-fluorobenzoate was utilized and totally degraded after a short period of adaptation. The isoenzymes for total degradation of chlorocatechols, being found during growth with 3-chlorobenzoate or 4-chlorophenol, were not induced in the presence of fluorobenzoates. Correspondingly, only the ordinary enzymes of the benzoate pathway were detected in 4-fluorobenzoate-grown cells. Ring cleavage of 3-fluorocatechol was recognized as a critical step in 3-fluorobenzoate degradation. 2-Fluoro-
cis,cis
-muconic acid was identified as a dead-end metabolite from 2- and 3-fluorobenzoate catabolism. During 2-fluorobenzoate cometabolism, fluoride is eliminated by the initial dioxygenation.

Abstract
Pseudomonas sp. B13 was grown in continuous culture on 4-chlorophenol as the only carbon source. Maximum growth rate of 0.4 h(-1) was observed at a substrate concentration of greater than 0.01 mM and less than 0.15 mM. In addition to the enzymes of phenol catabolism, high specific 1,2-dioxygenase activities with chlorocatechols as substrates were found. The isomeric monochlorinated phenols were also totally degraded by 4-chlorophenol grown cells. (+)-2,5-Dihydro-4-methyl- and (+)-2,5-dihydro-2-methyl-5-oxo-furan-2-acetic acid were formed in high yield as dead-end catabolites from cooxidation of cresoles. Several dichlorophenols except 2,6-dichlorophenol were removed from the culture fluid by chlorophenol grown cells. Ring cleavage of chlorinated catechols were shown to be one of the critical steps in chlorophenol catabolism. A catabolic pathway for isomeric chlorophenols is discussed.
