Abstract: An analysis is presented of inclusiveπ 0 production inZ 0 decays measured with the DELPHI detector. At low energies,π 0 decays are reconstructed by using pairs of converted photons and combinations of converted photons and photons reconstructed in the barrel electromagnetic calorimeter (HPC). At high energies (up to $$x_p = 2 \cdot p_\pi /\sqrt s = 0.75$$ ) the excellent granularity of the HPC is exploited to search for two-photon substructures in single showers. The inclusive differential cross section is measured as a function of energy forqq andbb events. The number ofπ 0’s per hadronicZ 0 event isN(π 0)/Z 0 =9.2±0.2(stat)±1.0(syst) and forbb events the number ofπ 0’s is N(π 0)/bb=10.1±0.4(stat)±1.1(syst). The ratio of the number ofπ 0’s inbb events to hadronicZ 0 events is less affected by the systematic errors and is found to be 1.09±0.05±0.01. The measuredπ 0 cross sections are compared with the predictions of different parton shower models. For hadronic events, the peak position in theξ p=ln(1/xp) distribution isξ* p =3.90 −0.14 +0.24 . The average number ofπ 0’s from the decay of primary B hadrons is found to be N(B→π 0 X)/B hadron=2.78±0.15(stat)±0.60(syst).

Abstract: Two-particle angular correlations in jet cones have been measured in e(+)e(-) annihilation into hadrons at LEP energies (root s = 91 and 183 GeV) and are compared with QCD predictions using the LPHD hypothesis. Two different functions have been tested. While the differentially normalized correlation function shows substantial deviations from the predictions, a globally normalized correlation function agrees well. The size of alpha(s)(eff) land other QCD parameters) and its running with the relevant angular scale, the validity of LPHD, and problems due to non-perturbative effects are discussed critically.

Abstract: Bose-Einstein correlation between pairs of like-sign charged particles produced in e+e- annihilations near the Z0 peak have been studied using data taken with the DELPHI detector at LEP. An enhancement is found in the production of pairs of identical pions of similar moments, with respect to a reference sample. Under the hypothesis that the pions are emitted by a spherically symmetrical source with gaussian density, the data indicate a radius of the source of r = 0.62±0.04(stat.)±0.20(syst.) fm. The large systematic uncertainty reflects the sensitivity of r to the choice of the reference sample, 0, info:eu-repo/semantics/published

Abstract: The constantly occurring cases of environmental pollution of water by chemicals and pharmaceuticals and their degradation products show the importance of a close surveillance of potential bioactive substances in water. Common chemical sensors detect known substances with high sensitivity, but their bioactivity remains unknown. The innovative cell based sensor technology uses eukaryotic cells as the sensitive layer for an online cytotoxicity sensor. Therefore this technology may be used for evaluation of the cytotoxic and bioactive potential of water. To prove the usability of eukaryotic cells as sentinels for water pollution we show the cultivation, their vitality and metabolic activity of several cell types growing on the silicon surface of the metabolic chip (Micronas) using the Bionas 2500 analyzing system (Bionas). With the most feasible cell type a close to application trial was performed.

Abstract: BACKGROUND Aim of this study was to assess the direct costs of Parkinson's disease (PD) within a 3-month period (i.e. the accounting period for the German statutory health insurance) in 12 neurological outpatient practices in Berlin during 2006. MATERIAL AND METHODS A total of 425 patients (age 69.1+/-9.3 years, 185 females) were recruited, and sociodemographic and clinical data were obtained by a specific questionnaire. The distribution of costs was analyzed based on several clinical and patient parameters. The costs were calculated with different approaches: (1) prospectively, with the practices' accounting according to German uniform scales (GoA, EbM) and (2) retrospectively, with questionnaires for the Parkinson's patients. Costs were calculated according to current German guidelines of the statutory health insurance. Clinical parameters were assessed with a questionnaire for physicians. RESULTS The direct medical costs totaled 1,667 EUR (range 1,436-1,995 EUR, CI 95%) per patient per 3 months. Charges by physicians were 42 EUR (39-45 EUR, CI 95%) for patients with statutory health insurance and 135 EUR (106-177 EUR, CI 95%) for those with private insurance. Disease severity and disease duration correlated with higher direct medical costs. Motor fluctuations and depression also were major factors influencing cost. CONCLUSION Our study emphasizes the large economic burden caused mainly by PD medication and hospitalization. For the first time a direct comparison between costs and actual physicians' reimbursement was possible. In combination with further economic studies, this comparison will help to define shortcomings and excesses in PD health care services.

Abstract: In order to avoid dyskinesias, de novo Parkinson patients are preferentially treated with dopamine agonists. Dopamine agonists can be classified into ergot- and non-ergot derivatives. Most recent investigations indicate that dopamine agonists of the ergot type carry an increased risk of restrictive valvular heart disease. This is particularly the case for pergolide and cabergoline. On average, about 18 % of individuals over the age of 50 with risk factors such as arterial hypertension, diabetes mellitus or nicotine abuse also present with a vavulopathy, whilst 25 % of patients treated with pergolide and cabergoline show such abnormalities. The clinical relevance of these restrictive heart valve abnormalities is limited, because only 1 % of all patients present with indicative clinical symptoms such as shortness of breath or edema. Nevertheless, pergolide and cabergoline have now been downgraded to second-line treatment of Parkinson's disease.

Abstract: In this work cell adhesion and cellular response to metal compounds classified as cytotoxic and carcinogenic are assessed by electrical impedance measurement in a 96-well plate prototype. This system integrates at the bottom of each well interdigitated electrodes to monitor in real time the electrical impedance changes at the electrode/culture medium interface due to cell adhesion, considered as a index of cell viability. The cytotocixity of sodium arsenite, cadmium chloride and cis-platinum is assessed on-line on BALB/3T3 A-31-1-1 cell line, a well known model to evaluate cytotoxicity and carcinogenic potential of chemicals. The inhibitory half concentration (IC50) is calculated from the impedance data normalized to the control and compared with conventional methods used to study basal cytotoxicity of chemicals in BALB/3T3 cell line model, such as colony forming efficiency (CFE) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays. The results suggest similar behavior of cytotoxicity induced by tested chemicals assessed by the three tests compared even if CFE remains the more sensitive. However, the impedance-based on-line measuring 96-well plate method is, on our point of view, the less laborious and easier test. The cytotoxicity of cobalt as micron and nanoparticles is also evaluated revealing the possibility for the system to monitor on-line and with high throughput new chemicals.

Abstract: Practical resistance to sterol demethylation inhibitor (DMI) fungicides among populations of Blumeriella jaapii, the cherry leaf spot (CLS) pathogen, was documented in 2005. In the present study, strategies to reduce selection for DMI-resistant strains of B. jaapii and adapt to possible restrictions on the use of chlorothalonil are described. Ten field trials were conducted on the sour cherry cultivars Balaton and Montmorency to test the efficacy of integrating respiration-inhibitor and copper-based fungicides into spray programs. Programs that included up to three sprays of copper-based fungicides were among the most effective for controlling CLS, although leaf phy-totoxicity was sometimes observed. Under high disease pressure, eliminating chlorothalonil compromised CLS control. ‘Balaton’ and ‘Montmorency’ did not differ in the percentage of leaves with CLS or defoliation resulting from CLS. The physical modes of action of representative DMI, QoI, and copper-based fungicides were evaluated in a leaf disk assay. Trifloxystrobin, a QoI fungicide, provided the best protection against infection by B. jaapii. All fungicides were more effective than water when applied 46 h postinfection, although differences were not statistically significant in one of two trials. Tebuconazole, a DMI, was the only fungicide that was more effective than water in preventing resporulation from existing lesions in both trials. Isolates of B. jaapii, which varied in DMI-sensitivity, all were sensitive to copper in vitro.

Abstract: Reliable, language-independent, short screening instruments to test for cognitive function in patients with multiple sclerosis (MS) remain rare, despite the high number of patients affected by cognitive decline. We developed a new, short screening instrument, the Faces Symbol Test (FST), and compared its diagnostic test characteristics with a composite of the Digit Symbol Substitution Test (DSST) and the Paced Auditory Serial Addition Test (PASAT), in 108 MS patients and 33 healthy controls. An Informant-Report Questionnaire, a Self-Report Questionnaire, and a neurologist's estimation of the Every Day Life Cognitive Status were also applied to the MS patients. The statistical analyses comprised of a receiver operating characteristic analysis for test accuracy and for confounding variables. The PASAT and DSST composite score estimated that 36.5% of the MS patients had cognitive impairment. The FST estimated that 40.7% of the MS patients were cognitively impaired (sensitivity 84%; specificity 85%). The FST, DSST and PASAT results were significantly correlated with the patients' physical impairment, as measured by the Expanded Disability Status Scale (EDSS). The results suggest that the FST might be a culture-free, sensitive, and practical short screening instrument for the detection of cognitive decline in patients with MS, including those in the early stages.

10. Occurrence, Distribution, and Polymerase Chain Reaction-Based Detection of Resistance to Sterol Demethylation Inhibitor Fungicides in Populations of Blumeriella jaapii in Michigan

Abstract: The intensive use of site-specific fungicides in agricultural production provides a potent selective mechanism for increasing the frequency of fungicide-resistant isolates in pathogen populations. Practical resistance occurs when the frequency and levels of resistance are great enough to limit the effectiveness of disease control in the field. Cherry leaf spot (CLS), caused by the fungus Blumeriella jaapii, is a major disease of cherry trees in the Great Lakes region. The site-specific sterol demethylation inhibitor fungicides (DMIs) have been used extensively in the region. In 2002, CLS control failed in a Michigan orchard that had used the DMI fenbuconazole exclusively for 8 years. That control failure and our observations from around the state suggested that practical resistance had developed in B. jaapii. Field trial data covering 1989 to 2005 for the DMIs fenbuconazole and tebuconazole supported observations of reduced efficacy of DMIs for controlling CLS. To verify the occurrence of fungicide-resistant B. jaapii, monoconidial isolates were collected in two surveys and tested using a fungicide-amended medium. In one survey, 137 isolates from sites with different DMI histories (no known history, mixed or alternated with other fungicides, and exclusive use) were tested against 12 concentrations of fenbuconazole, tebuconazole, myclobutanil, and fenarimol. Isolates from sites with no prior DMI use were DMI sensitive (DMIS = no colony growth at 0.2 μg/ml a.i.) whereas the isolates from the site with prior exclusive use showed growth at DMI concentrations 3 to >100 times higher, and were rated as DMI resistant (DMIR). A second survey examined 1,530 monoconidial isolates, including 1,143 from 62 orchard sites in Michigan, where DMIs had been used to control CLS. Resistance to fenbuconazole was detected in 99.7% of the orchard isolates. All isolates from wild cherry trees were sensitive and isolates from feral and dooryard trees showed a range of sensitivities. A polymerase chain reaction (PCR)-based detection method for identifying B. jaapii and DMIR was developed and tested. The species-specific primer pair (Bj-F and Bj-R) based on introns in the CYP51 gene of B. jaapii, and the DMIR-specific primer pair (DMI-R-Bj-F and DMI-R-Bj-R) based on an insert found upstream of CYP51 in all DMIR isolates, provided an accurate and rapid method for detecting DMIR B. jaapii. The PCR-based identification method will facilitate timely decision making and continued monitoring of DMIR subpopulations in response to management programs.

Abstract: ZusammenfassungBei Parkinson sind zunehmend nicht motorische Symptome von Bedeutung. Deshalb sollte durch die dopaminerge Therapie neben guter motorischer Wirksamkeit ein möglichst positiver Einfluss auf nicht motorische Symptome erreicht werden. Der Non-Ergot Dopaminagonist (DA) Piribedil besitzt ein spezifisches Rezeptorprofil mit D2/D3-Agonismus und α2-Antagonismus. Bei einer 67-jährigen Patientin mit Tagesmüdigkeit unter PramipexolVormedikation traten unter Therapie mit Ropinirol, L-Dopa und Rasagilin motorische Probleme auf. Zudem bestanden leichte Beinödeme und ein deutliches depressives Syndrom. Der DA wurde auf Piribedil gewechselt. Nach Therapieumstellung und weiterer Dosisanpassung besserte sich die Motorik ohne Auftreten von Tagesmüdigkeit. Die Ödeme gingen zurück und bei deutlich gebesserter Stimmungslage konnte der eindosierte SSRI abgesetzt werden. Ein DA-Wechsel kann bei Auftreten spezifischer Probleme günstig sein. Bei guter motorischer Wirksamkeit zeigte Piribedil in dieser Kasuistik Vorteile in Bezug auf Tagesmüdigkeit und Ödeme mit zusätzlich antidepressiver Wirkung.

Abstract: Due to their amphiphilic properties, detergents readily disrupt cellular membranes and cause rapid cytolysis. In this study we demonstrate that treatment of cells with sublytic concentrations of detergents such as Triton X-100, Nonidet P-40, n-octylglucoside and the bile salt sodium deoxycholate induce typical signs of apoptosis including DNA fragmentation and cleavage of poly(ADP-ribose) polymerase molecules. The detergent concentration required for apoptosis was below the critical micellar concentration. Induction of apoptosis was not restricted to human cells but similarly occurred in a variety of other vertebrate cell lines. Unstimulated peripheral blood mononuclear cells were susceptible to apoptosis induction by detergent suggesting that apoptosis in this circumstance is not mediated by CD95. Cell death was not due to influx of calcium from the medium. Apoptosis was blocked and cytolysis prevented by treatment with peptide inhibitors of caspases. These findings suggest a process of apoptosis that is initiated upon nonspecific alterations at the cell membrane level. Physiologic correlates of this process still have to be defined.

Abstract: The pH in the cellular microenvironment (pH(M)) is an important regulator of cell-to-cell and cell-to-host interactions. Additionally the extracellular acidification rate of a cell culture is an important indicator of global cellular metabolism. In a new approach a biocompatible ion-sensitive field effect transistor (ISFET)-array was developed to measure the pH(M) close to a surface and the global extracellular acidification rate at the same time. This ISFET-array is part of a new multiparametric microsensor chip. The paper highlights some basic applications of this method for in-vitro measurements. Using a fluid perfusion system for cell culture media, it is possible to measure the pH(M) of few (five to ten) adherent tumor cells in a distance of 10-100 nm from the cell plasma membrane. Experiments showed a pH(M)-value of 6.68 +/- 0.06 pH. Further experiments suggest that both the low pH, and the extracellular acidification rate of the examined tumor cell line are mainly built up by glycolysis.

Abstract: Zusammenfassung Eine prazise Charakterisierung des physiologischen Reaktionsverhaltens von Zellen ist entscheidend fur die Beantwortung einer Vielzahl zellbiologischer, pharmakologischer und medizinischer Fragestellungen. Bei Standard-Testverfahren gehen zumeist wertvolle Informationen zum dynamischen Verlauf der zellularen Reaktionen verloren. Auserdem wird fast immer nur ein einziger Testparameter erfast, obwohl sich zellulare Reaktionen stets in einer Vielzahl verschiedener Teilaspekte ausern. Eine Signalanalyse mit mikrosensorischen Systemen eignet sich dank des ruckwirkungsfreien und kontinuierlichen Mesvorgangs gut zur Gewinnung und Analyse funktionsrelevanter Signale an kultivierten Zellen und Gewebepraparationen. Daher haben wir mit verschiedenen Mikrosensoren bestuckte Testsysteme entwickelt, die ihre Anwendung in zahlreichen Gebieten der biomedizinischen und zellbiologischen Forschung finden konnten. Aufbauend auf den in-vitro eingesetzten Versionen werden auch Konzepte zu sensorgestutzten Ansatzen in der Tumortherapie vorgestellt.

Abstract: Living cells can be considered as complex biochemical plants. Biochemical and biophysical processes enable a cell to maintain itself, to grow, to reproduce and to communicate with the environment. Getting more information about the multifunctional cellular processing of input- and output-signals in different cellular plants is essential for basic research as well as for various fields of biomedical applications. For in-vitro investigations on living cells, the cellular environment differs from the native environment found in vivo. As a first approach for on-line monitoring of cellular reactions under well controlled experimental conditions we have developed the so called Cell Monitoring System (CMS ® ). It allows parallel and non-invasive measurement of different parameters from cellular systems by the use of microsensors. Microelectronic sensors are the adequate choice for the non-invasive measurement of environmental—as well as in- and output—parameters of cells. In this paper we present a measurement system with pH-sensitive ISFETs (ionsensitive fieldeffect transistors) for the measurement of extracellular pH-related signals on cells and tissues.

Abstract: The total and the differential cross sections for the reaction e+e− → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb−1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ− > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10−5, 5.5 × 10−5, 8.0 × 10−5, and 1.7 × 10−5 respectively. All the limits are at the 95% confidence level.

Abstract: A search for stable or long-lived heavy charged particles in e+e− interactions at energies of 130–136, 161 and 172 GeV has been performed using the data taken by the DELPHI experiment at LEP. The search is based on particle identification provided by the Time Projection Chamber and the Ring Imaging Cherenkov detector. Upper limits at 95% confidence level are derived on the cross-section for heavy long-lived pair-produced charge ±e and View the MathML source particles in the range of 0.4–2.3 pb for masses from 45 to 84 GeV/c2. Within supersymmetric extensions of the Standard Model, long-lived charginos with masses from 45 to 84 (80) GeV/c2 for high (low) sneutrino masses can be excluded at 95% confidence level. Left-handed (right-handed) long-lived or stable smuons and staus with masses between 45 and 68 (65) GeV/c2 can be excluded at 95% confidence level.

Abstract: We have searched for excited states of charged and neutral leptons, e∗, μ ∗ , τ ∗ and ν ∗ , in e+e− collisions at s =130 using the OPAL detector at LEP. No evidence for their existence was found. With the most common coupling assumptions, the final states from excited lepton pair production include l+l−γγ and l+l−WW (with the subsequent decay of the virtual W bosons). From the analysis of these final states, 95% confidence level lower mass limits of 66.5 GeV for e∗, 66.8 GeV for μ ∗ , 65.3 GeV for τ ∗ , 66.2 GeV for ν e ∗ , 66.5 GeV for ν μ ∗ and 64.7 GeV for ν τ ∗ are inferred. From the analysis of γγ final states with missing energy and using alternative coupling assignments which permit photonic ν ∗ decays, a 95% confidence level lower mass limit of 65.0 GeV for each ν ∗ flavour is inferred. From the analysis of the l+l−γ, acoplanar lepton pair, and single γ final states expected from excited lepton single production, upper limits on f Λ (ratio of the coupling to the compositeness scale) are determined for excited lepton masses up to the kinematic limit.

Author: R. Ehret
Subjects: Neurology (clinical), Family Practice
Abstract: ZusammenfassungBei fortschreitender Erkrankung können bei Parkinson-Patienten hypo- und hyperkinetische, oft fluktuierende Komplikationen auftreten, die in der Arztkonsultation meist nicht sichtbar sind und eine nicht unerhebliche Herausforderung an die Therapie darstellen. Seit kurzem wird ein System der ambulanten Videoüberwachung speziell für die Beobachtung von Parkinson-Patienten zu Hause angeboten. Im Beitrag werden erste Erfahrungen aus einer Berliner Facharztpraxis mit Schwerpunkt in der Versorgung von Parkinson-Patienten dargestellt.

Abstract: Using data accumulated by DELPHI during the November 1995 LEP run at 130–136 GeV, searchs have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.

Abstract: During the last 1995 data acquisition period at LEP, the DELPHI experiment collected an integrated luminosity of 5.9 pb−1 at centre-of-mass energies of 130 GeV and 136 GeV. Radiative leptonic events (e, μ, τ) with high energy photons were studied and compared to Standard Model predictions. The data were used to search for charged excited leptons decaying through an electromagnetic transition. No significant signal was found. From the search for pair produced excited leptons, the limits View the MathML source, View the MathML source and View the MathML source at 95% confidence level were established. For single excited lepton production, upper limits on the ratio View the MathML source of the coupling of the excited charged lepton to its mass were derived.

Abstract: From the data collected by DELPHI at LEP in autumn 1995, the multiplicity of charged particles at a hadronic energy of 130 GeV has been measured to be 〈nch〉 = 23.84 ± 0.51 (stat) ± 0.52 (syst). When compared to lower energy data, the value measured is consistent with the evolution predicted by QCD with corrections at next-to-leading order, for a value αs(130 GeV) = 0.105 ± 0.003 (stat) ± 0.008 (syst).

Abstract: The MSSM distinguishes itself from other GUT's by a successful prediction of many unrelated phenomena with a minimum number of parameters. Among them: a) Unification of the couplings constants; b)Unification of the masses; c) Proton decay; d) Electroweak symmetry breaking. A combined fit of the free parameters in the MSSM to these low energy constraints shows that the MSSM model can satisfy these constraints simultaneously. From the fitted parameters the masses of the as yet unobserved superpartners of the SM particles are predicted. The 2nd order QCD coupling constant is required to be between 0.108 and 0.132. It is shown that a top mass of $174\pm16$ GeV, as suggested recently by the CDF Collaboration, constrains the mixing angle between the Higgs doublets in the MSSM to: $1.2

Abstract: A measurement of B meson lifetimes is presented using data collected from 1991 to 1993 by the DELPHI detector at the LEP collider. Samples of events with a D meson and a lepton in the same jet are selected where$\bar D^{^0 } \ell ^ + $ and D*l+ events originate mainly from the semileptonic decays of B+ and B0 mesons, respectively. From the reconstructed B decay length and the estimated B momentum, taking into account the dilution due to B decays into$\bar D^{^{**} } \ell ^ + v$, the following B meson lifetimes and lifetime ratio are measured: $$\begin{gathered} \tau (B^ + ) = 1.61_{ - 0.16}^{ + 0.16} (stat.) \pm 0.12(syst.) ps \hfill \\ \tau (B^0 ) = 1.61_{ - 0.13}^{ + 0.14} (stat.) \pm 0.08(syst.) ps \hfill \\ \tau (B^ + )/\tau (B^0 ) = 1.00_{ - 0.15}^{ + 0.17} (stat.) \pm 0.10(syst.) \hfill \\ \end{gathered} $$ and an average lifetime of B+ and B0 mesons is obtained: $$\tau (B) = 1.61_{ - 0.07}^{ + 0.08} (stat.) \pm 0.05(syst.) ps$$

Abstract: A sample of events enriched in bb̄ quark pairs was selected in the data recorded by the DELPHI experiment at LEP during 1992 and 1993, by the presence of secondary decay vertices from short-lived particles. Using this sample, the average multiplicities of Ks0, K±, p(p̄), Λ(View the MathML source) and of charged particles in bb̄ events have been measured, distinguishing the component from fragmentation and the component coming from the decay of b-hadrons. The measurement of the average charge multiplicity in bb̄ events was used to compute the mean fractional beam energy carried by the primary b-hadron, and the difference in charged particle multiplicity between bb̄ events and light quark (uū, dd̄, ss̄) events.

Abstract: Experimental evidence for the existence of orbitally excited B meson states is presented in an analysis of the BÏ and B*Ï distribution of Q = m(B**) - m(B(*)) - m(Ï) using Z0decay data taken with the DELPHI detector at LEP. The mean Q-value of the decays B**â B(*)Ï is measured to be 284 Â± 5 (stat.) Â± 15 (syst.) MeV/c2, and the Gaussian width of the signal is 79 Â± 5 (stat.) Â± 8 (syst.) MeV/c2. This signal can be described as a single resonance of mass m = 5732 Â± 5 (stat.) Â± 20 (syst.) MeV/c2and full width Î = 145 Â± 28 MeV/c2. The observed shape is also consistent with the production of several broad and narrow states as predicted by the quark model and partly observed in the D-meson sector. The production rate of B**per b-jet is found to be 0.27 Â± 0.02 (stat.) Â± 0.06 (syst.). Â© 1995.

Abstract: The production of multihadronic states in γγ collisions at LEP has been studied with the DELPHI detector. The analyzed data correspond to an integrated luminosity of about 32pb−1, collected in the LEP runs of 1990–1992. Minimum bias data and a sample of events with jets at highpT have been selected under the requirement that no scattered electron or positron is observed. The two data sets have been compared to Monte Carlo predictions. The non-perturbative contribution described by the vector meson dominance Model and direct$q\bar q$ production from pointlike photons described by the quark parton model were found to be insufficient to reproduce the data. It has been necessary to include a third interaction component, which is due to perburbative hard scattering of the partonic constituents of the photon. Several parametrisations of the quark and gluon densities of the photon have been tested. The interplay with the cut in jet transverse momentum, which is necessary for the separation of the perturbative and non-perturbative regions, is discussed. The data favour parametrisations with rather soft partonic content of the photon.

Abstract: The total and the differential cross sections for the reaction e+e− → γγ(γ) have been measured with the DELPHI detector at LEP using an integrated luminosity of 36.9 pb−1. The results agree with the QED predictions and consequently there is no evidence for non-standard channels with the same experimental signature. The lower limits obtained on the QED cutoff parameters are Λ+ > 143 GeV and Λ− > 120 GeV, and the lower bound on the mass of an excited electron with an effective coupling constant λγ = 1 is 132 GeV/c2. Upper limits on the branching ratios for the decays Z0 → γγ, Z0 → π0γ, Z0 → ηγ and Z0 → γγγ have been determined to be 5.5 × 10−5, 5.5 × 10−5, 8.0 × 10−5, and 1.7 × 10−5 respectively. All the limits are at the 95% confidence level.

Abstract: An analysis of the production of the Λ baryon in the hadronic decays of the Z0 is presented, based on about 993K multihadronic events collected by the DELPHI detector at LEP during 1991 and 1992. The differencial cross section of the Λ and the correlations between Λ and View the MathML source produced in the same event are compared to current models, based both on string fragmentation and on cluster decay. The predictions of the string fragmentation model are found to give satisfactory agreements with the data, clearly better than those of the cluster model.

Abstract: A study of inclusive production of the meson resonances ρ0, K*0 (892), f{hook}0 (975) and f{hook}2 (1270) in hadronic decays of the Z0 is presented. The measured mean meson multiplicity per hadronic event is 0.83 ± 0.14 for the ρ0 0.64 ± 0.24 for the K*0 (892), 0.10 ± 0.04 for the f{hook}0 (975) in the momentum range p > 0.05pbeam (xp > 0.05) and 0.11 ± 0.05 for the f{hook}2 (1270) for xp > 0.1. These values and the corresponding differential cross sections ( 1 σhadr) dσ dxp for the vector mesons are in good agreement with the predictions of the JETSET 7.3 PS and HERWIG 5.4 models. The f{hook}2 (1270) production is overestimated by HERWIG but its xp-shape is correctly reproduced. The measured ratios of the production cross sections σ(f{hook}2(1270)) σ(ρ0) = 0.22 ± 0.08 and σ(f{hook}2(1270)) σ(f{hook}0(975)) = 3-1 +7 for xp > 0.1 are consistent with the results obtained in hadronic reactions. © 1993.

Abstract: Phytoestrogens are naturally occurring, plant-derived, nonsteroidal phytochemicals with anticarcinogenic potential. The aim of this study was to isolate phytoestrogens from the flax root of Linum usitatissimum and to test their effect on cellular metabolism in the human mammalian carcinoma cell line MCF-7 using the Bionas 2500 analysis system.Metabolically relevant parameters such as acidification, oxygen consumption and cell adhesion were registered continuously over 8 and 24 hours on six sensor chips in parallel at different concentrations of flax root extracts.The extracts from flax roots of L. usitatissimum reduced extracellular acidification, respiration and adhesion in a concentration-dependent manner.The Bionas 2500 analysis system allows multiparametric online monitoring of cellular processes and can be used to detect the mode of action of anticarcinogenic compounds in cellular metabolism.

Abstract: Aim of this study was to assess the direct costs of Parkinson's disease (PD) within a 3-month period (i.e. the accounting period for the German statutory health insurance) in 12 neurological outpatient practices in Berlin during 2006.A total of 425 patients (age 69.1+/-9.3 years, 185 females) were recruited, and sociodemographic and clinical data were obtained by a specific questionnaire. The distribution of costs was analyzed based on several clinical and patient parameters. The costs were calculated with different approaches: (1) prospectively, with the practices' accounting according to German uniform scales (GoA, EbM) and (2) retrospectively, with questionnaires for the Parkinson's patients. Costs were calculated according to current German guidelines of the statutory health insurance. Clinical parameters were assessed with a questionnaire for physicians.The direct medical costs totaled 1,667 EUR (range 1,436-1,995 EUR, CI 95%) per patient per 3 months. Charges by physicians were 42 EUR (39-45 EUR, CI 95%) for patients with statutory health insurance and 135 EUR (106-177 EUR, CI 95%) for those with private insurance. Disease severity and disease duration correlated with higher direct medical costs. Motor fluctuations and depression also were major factors influencing cost.Our study emphasizes the large economic burden caused mainly by PD medication and hospitalization. For the first time a direct comparison between costs and actual physicians' reimbursement was possible. In combination with further economic studies, this comparison will help to define shortcomings and excesses in PD health care services.

Abstract: Drug resistance interpretation systems are used to select the optimal antiretroviral therapy in HIV-infected patients. It is unclear how the systems perform in predicting therapy success and failure and in how far the interpretations are affected by insufficient drug levels.The accuracy of nine different interpretation systems in predicting therapy outcomes was evaluated using virological, immunological, pharmacological, and clinical data of 130 patients treated at 13 outpatient centers. Individual susceptibility scores of the interpretation systems were converted into active drug scores (ADS) and correlated with therapy success and failure, defined as viral load reduction of equal to or more (n=66) and less than 1 log10 copies/ml (n=64) at three months after drug resistance testing.Three interpretation systems considered the respective therapies as more active compared to the other interpretation systems (p0.01). These systems predicted therapy success better than the other systems, while the others performed better in predicting therapy failure. Thus, the overall rate of correctly predicted treatment outcomes was comparable between the different systems (73.1-80.0 %). Univariate and multivariate regression analysis revealed significant correlations between the ADS of all interpretation systems and virological therapy outcomes (p0.0001). In contrast, only three interpretation systems were significantly correlated with immunological therapy outcomes in univariate and just one in multivariate models (p0.05). Among 128 determinations of drug levels in 64 patient samples, 19.4 % revealed no detectable drug levels. The consideration of insufficient drug levels significantly improved the prediction accuracy of all interpretation systems (p0.005).Differences between interpretation systems in predicting therapy failures and success need to be considered for future consensus algorithms. The prediction accuracy of interpretation systems can be improved by consideration of plasma drug levels.

Abstract: A multiparametric chip-based system was employed to measure cell adhesion, metabolism, and response to metal compounds previously classified as cytotoxic in immortalized mouse fibroblasts (BALB/3T3 cell line). The system measures in parallel, online, and in label-free conditions the extracellular acidification rates (with pH-sensitive field effect transistors [ISFETs]), the cellular oxygen consumption (with amperometric electrode structures [Clark-type sensors]), and cell adhesion (with impedimetric interdigitated electrode structures [IDESs]). The experimental protocol was optimized to monitor metabolism and adhesion of the BALB/3T3 cell line. A total of 70,000 cells and a bicarbonate buffer-free running low-glucose Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal clone serum III and 1mM Hepes were selected to maintain cells in good conditions on the chip during the measurements performed under perfusion conditions. Cells were exposed to sodium arsenite, cadmium chloride, and cis-platinum at concentrations ranging from 1 to 100 microM. The kinetics of cell response to these compounds was analyzed and suggests that the Clark-type sensors can be more sensitive than IDESs and ISFETs in detecting the presence of high chemical concentration when short exposure times (i.e., 2h) are considered. The cytotoxicity data obtained from the online measurements of acidification, respiration, and adhesion at 24h compare well, in terms of half-inhibition concentration values (IC(50)), with the ones obtained using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test and colony-forming efficiency (CFE) assay. The results show a good sensitivity of the system combined with the advantages of the online and label-free detection methods that allow following cell status before, during, and after the treatment in the same experiment.
