Die Rot‐Eiche (Quercus rubra L., Fagaceae) als stark mykotrophe Gehölzart – ein Vergleich der Makromyzetenflora unter Rot‐Eichen und einheimischen Eichen in der Umgebung von Potsdam, Deutschland
Authors: Sammler P. 
Published: May 2004

AbstractIn den Jahren 1998–2002 wurde die Fruktifikation von Makromyzeten in Rot‐Eichen‐Reinbeständen auf fünf ausgewählten Parzellen untersucht und mit derjenigen unter einheimischen Eichen (Q. petraea, Q. robur) auf angrenzenden Parzellen verglichen. Unter Rot‐Eichen bzw. einheimischen Eichen fruktifizierten insgesamt 50/63 Ektomykorrhiza‐Pilzarten, 40/52 terrestrische Saprophyten und 47/32 lignikole Pilzarten. Die Abundanz der Fruchtkörperbildung war bei den terrestrischen Makromyzeten unter Quercus robur/Q. petraea größer als unter Q. rubra. Als eine wesentliche Ursache für die höhere Artenanzahl und Abundanz von Makromyzeten unter einheimischen Eichen wird das unterschiedliche Alter der Bestände [durchschnittlich (60)–80 > 80 Jahre bei Q. petraea/Q. robur und 30–60 (80) Jahre bei Q. rubra] vermutet.Die erhaltenen Ergebnisse hinsichtlich der Artendiversität bei der Ektomykorrhiza‐Bildung zeigen aber auch, dass die Rot‐Eiche auf sauren und schwach sauren, nährstoffärmeren Standorten in Brandenburg ein annähernd gleich hohes Potential wie die einheimischen Eichen aufweist.

Kommentiertes Verzeichnis der Flechten und flechtenbewohnenden Pilze Brandenburgs, Deutschland – zweite Fassung
Authors: Otte V. , Rätzel S. 
Published: May 2004

AbstractFünf Jahre nach Erscheinen der ersten wird eine neue Zusammenstellung der in Brandenburg (einschließlich Berlins) nachgewiesenen Flechten und lichenicolen Pilze vorgelegt. Die Gefährdung der Sippen wird eingeschätzt und erstmals ihre Verbreitung in den Naturräumen dargestellt. Die Zahl der Taxa ist gegenüber der letzten Liste um 20 % gestiegen. Zahlreiche verschollene Sippen konnten wiederaufgefunden werden. Viele säureempfindliche Epiphyten sind infolge verbesserter Luftqualität in Wiederausbreitung. Nicht gebessert hat sich die Situation bei typischen Alleebaumflechten, vielen Arten der Agrarlandschaft und Besiedlern alter Gemäuer. Die für Brandenburg typischen Erdflechten sind z.T. noch weit verbreitet, aber tendenziell rückläufig und einige Arten hochgradig gefährdet oder verschwunden. (© 2004 WILEY‐VCH Verlag GmbH & Co.

Glechoma hederacea (Lamiaceae) in North America: invasion history and current distribution
Authors: Scholler M. , Böllmann J. 
Published: May 2004

AbstractGlechoma hederacea L. (Ground‐ivy, Lamiaceae), a perennial mat‐forming herb, is native to the temperate regions of Eurasia and was introduced elsewhere (South East Asia, New Zealand and North America). Based on data obtained from herbaria, literature, online and other data bases and field studies, we documented the invasion history and current distribution of this plant in North America. At present, the plant is recorded from all but two continental states of the USA and all southern provinces of Canada. There are two main ranges: the larger one covers mainly the eastern part of the U.S.A. and a smaller one stretches along the West Coast. While published records of Glechoma hederacea date from 1814, the oldest specimen is from 1829. During the 19th century the species spread westwards at a rate of approximately 30 km/year. The spread and present range of G. hederacea can only be explained by climatic factors (degree of oceanicity) and considering human activity. Especially long distance propagation of vegetative parts of the plants and the change of the environment that accompanies human settlements may have had a major influence on these processes.

Nonlinearity of FMRI responses in human auditory cortex
Authors: Talavage Thomas M. , Edmister Whitney B. 
Published: May 2004

AbstractAn investigation was made into the nature of the nonlinearity observed in auditory functional magnetic resonance imaging (fMRI) experiments associated with increases in total duration of acoustic imaging noise [e.g., Edmister et al., 1999; Shah et al., 1999]. A two‐stimulus, four‐condition paradigm was used to evaluate four acoustic conditions involving: (1) the presence or absence of a desired broadband music stimulus; and (2) two possible durations of trains of acoustic noise associated with image acquisition. Responses observed while increasing the duration of acoustic imaging noise were consistent with previous work (Talavage et al. [1999]: Hum Brain Mapp7:79–88) but the response to combined stimulation did not exhibit variation as a function of the acoustic imaging noise duration. These results suggest that spectral overlap of the stimuli produced colocalized responses that did not add linearly. This conclusion has implications for conducting both blocked and rapid‐presentation event‐related auditory fMRI experiments. The cortical activity induced by the stimulus may not reflect the activation, in spatial extent or magnitude of signal change, occurring in the absence of other acoustic noise. Hum.

Published: May 2004

AbstractThe immunosuppressive effect of cytotoxic drugs, basic therapeutic agents in the treatment of childhood acute leukemias, requires monitoring of the immune system following cessation of therapy. The cytokines are soluble proteins that play a key role in the immunoregulation of the lymphocyte function. The cytokines regulate growth, differentiation and function of various cells in normal conditions. The aim of our study was to estimate serum levels of IL‐2, IL‐6, IL‐8, IL‐10 and TNF‐alpha in children with acute lymphoblastic leukemia (ALL) after cessation of chemotherapy. The study involved 150 children with ALL. This group consisted of: 30 children 1 month after treatment cessation; 30 children, 3 months later; 30 children 6 months later; 30 children, 9 months later and 30 children, 12 months later. The control group consisted of 30 healthy children. The levels of the cytokines under study were assayed using the immunoassay kits (R&D Systems, USA). During the study significant differences in TNF‐alpha, IL‐2 and IL‐8 serum concentrations were observed among treated children and controls. However there were no differences in IL‐6 and IL‐10 concentrations. Copyright © 2004 John Wiley & Sons, Ltd.

Published: May 2004

AbstractThis article provides an overview of issues related to the development and evaluation of competency in psychological assessment. Specifically, we delineate the goals, ideas, and directions identified by the psychological assessment work group in the Competencies Conference: Future Directions in Education and Credentialing in Professional Psychology. This is one of a series of articles published in this issue of the Journal of Clinical Psychology. Several other articles that resulted from the Competencies Conference will appear in Professional Psychology: Research and Practice and The Counseling Psychologist. The psychological assessment group was charged with the tasks of: (a) identifying the core components of psychological assessment competency; (b) determining the central educational and training experiences that will aid competency development; (c) explicating strategies for evaluating competence; and (d) establishing future directions for furthering the identification, training, and evaluation of competence in psychological assessment. We present a set of eight core competencies that we deemed important for achieving psychological assessment competency and discuss four guidelines for training in the domain of psychological assessment. A variety of methods for evaluating competencies in this domain are suggested, with emphasis on using a collaborative model of evaluation. Recommendations for future directions include strengthening the academic prerequisites for graduate school training; increasing training in culturally sensitive measures; incorporating innovative assessment‐related technologies into training; and addressing discontinuities between academic training, internship, and practice environments. © 2004 Wiley Periodicals, Inc.

Published: May 2004

AbstractWe report the design of a unique two‐plasmid production system for the first lentiviral vector to be evaluated in humans, VRX496. VRX496 is an optimized VSV‐G pseudotyped vector derived from HIV‐1 that expresses antisense to the HIV envelope gene. We found that a two‐plasmid approach to production resulted in higher vector production titers when compared with a three‐plasmid approach, which is particularly important for vector production at the large scale. Therefore, we carefully designed a single packaging construct, VIRPAC, for safety by reducing its homology with VRX496 and by insertion of functionally validated genetic elements designed to reduce the risk of generation of a replication‐competent lentivirus (RCL). A native cis‐acting ribozyme is used to prevent read through into the envelope gene from the upstream gag‐pol genes in the packaging vector, thus preventing RNAs containing gag‐pol and env together for comparable safety to a three‐plasmid system. We demonstrate that there is no significant in vivo vector mobilization using a primary SCID‐hu mouse transplantation model, which correlates with the presence of an anti‐HIV payload and suggests that inclusion of antisense may be a useful tool to restrict mobilization in other vector constructs. Gene transfer is achieved using a one‐step transduction procedure that is simple and clinically translatable, which reaches stable transduction efficiencies of >99% in CD4+ T lymphocytes within 3 days of culture initiation.

Evaluation of a new solid‐phase cartridge for the preconcentration of phenolic compounds in water
Authors: Sirvent Gemma , Hidalgo Manuela , Salvadó Victòria 
Published: May 2004

AbstractThe aim of this study is to evaluate the efficiency of a new solid‐phase extraction cartridge, Spe‐ed Advanta, in the extraction and preconcentration of four phenolic compounds (phenol, 2‐chlorophenol, 2‐nitrophenol, and 2,4‐dichlorophenol) from water. The solid phase is a polystyrene‐divinylbenzene resin modified with carboxylic groups, these polar groups improve the contact between the matrix and the aqueous solutions in the extraction of polar analytes. We studied several elution solvents in order to find the most efficient one. Sample concentration, sample volume, and sample pH are also investigated as well as the best method for drying the cartridge. Recoveries achieved with the new phase are compared with those obtained with Isolute ENV+, a non‐modified polystyrene‐divinylbenzene stationary bed. The best experimental conditions were then used for determination of the phenols in spiked environmental waters.
Definite peak identification of (R)‐and (S)‐methadone and (R)‐ and (S)‐EDDP using established HPLC and CE methods
Authors: Trkulja Sandra , Kovar Karl‐Artur 
Published: May 2004

AbstractMethadone is widely used for the treatment of opioid dependence. HPLC and CE are widespread methods for drug monitoring and metabolism studies. Although the methods are widely used for methadone and its main metabolite EDDP [1, 2], a definite direct peak identification for EDDP enantiomers is not described. This study describes a method for specific identification of each peak in the chromatogram and electropherogram of methadone analysis. The result of the study demonstrates differences in the elution order of the enantiomers of methadone and EDDP due to the technique used for analysis. The elution order of EDDP using HPLC is interchanged with respect to the order of the peaks in the electropherogram.
Quantitative analysis of caffeic acid phenethyl ester in crude propolis by liquid chromatography‐electrospray ionization mass spectrometry
Authors: Del Boccio Piero , Rotilio Domenico 
Published: May 2004

AbstractCaffeic acid phenethyl ester (CAPE), an active component of propolis from honeybee hives, is known to have antimitogenic, anticarcinogenic, antinflammatory, and immunomodulatory properties. The paper describes a rapid and simple liquid chromatography‐electrospray ionisation mass spectrometry method for qualitative and quantitative determination of CAPE. The chromatographic separation was performed with a Luna RP‐C18 column using a water‐acetonitrile linear gradient. The method was linear over a 0.125–80 ng/mL range (LOD = 62.5 pg/mL). The method was applied for the quantitation of caffeic acid phenethyl ester in crude propolis samples, which were analysed directly after extraction with ethyl acetate solution.

Published: May 2004

AbstractTwo Wall Coated Open Tubular capillary columns, coated with poly(cyanopropylphenyl‐dimethyl)siloxane and poly(diphenyl‐dimethyl)siloxane stationary phases, have been selected for use in the COmetary SAmpling and Composition space experiment for the separation and identification of the wide range of volatile organic compounds which could be present in cometary nuclei. This article presents the main characteristics of the tandem column system for the analysis of solutes of cometary interest within the constraints of space instrumental operating conditions. The high efficiency of the columns is demonstrated and the influence of the operating conditions on their separation properties are investigated. The studied columns exhibit complementary retention pattern: their use in a dual column system makes it possible to achieve the separation and the identification of the compounds of interest. Finally, the good analytical behavior of the columns when analyzing samples which include large amounts of water, the main presumed volatile in comets, is demonstrated. The presented results thus show the suitability of the selected tandem columns system for the desired analyses, and their performance on adaptation to in‐situ cometary chemical investigation.
Characterization of alkyl‐cobalamins formed on trapping of epoxide metabolites of 1,3‐butadiene

Published: May 2004

AbstractAnalytical methods facilitating studies of electrophilically reactive and genotoxic compounds in vitro and in vivo are needed. The strong nucleophile, cob(I)alamin, formed by reduction of Vitamin B12 [cob(III)alamin], may be used for trapping and analysis of 1,2‐epoxides and other electrophiles. In the present study, cob(I)alamin is evaluated as an analytical tool for 1,2‐epoxide metabolites (oxiranes) of 1,3‐butadiene. Products of reaction of cob(I)alamin with 1,2‐epoxy‐3‐butene (EB), 1,2:3,4‐diepoxybutane (DEB), and 1,2‐epoxy‐3,4‐butanediol (EBdiol) have been analyzed by reversed phase high performance liquid chromatography (HPLC) coupled on‐line to electrospray ionization mass spectrometry (ESI‐MS) and ultraviolet diode array detection (UV‐DAD). It was shown that a specific alkyl‐Cbl complex is formed for each metabolite and that it was possible to discriminate between the products by HPLC‐UV and by LC‐MS. Quantification of DEB with the method by use of another 1,2‐epoxide as an internal standard was successfully performed. The possibility of using cob(I)alamin for trapping and analysis of the three oxirane metabolites of 1,3‐butadiene will facilitate quantitative comparisons of species in vitro with regard to metabolism of 1,3‐butadiene.
