Abstract: Autophagy is usually a pro-survival mechanism in cancer cells, especially in the course of chemotherapy, thus autophagy inhibition may enhance the chemotherapy-mediated anti-cancer effect. However, since autophagy is strongly involved in the immunogenicity of cell death by promoting ATP release, its inhibition may reduce the immune response against tumors, negatively influencing the overall outcome of chemotherapy. In this study, we evaluated the in vitro and in vivo anti-cancer effect of curcumin (CUR) against Her2/neu overexpressing breast cancer cells (TUBO) in the presence or in the absence of the autophagy inhibitor chloroquine (CQ). We found that TUBO cell death induced by CUR was increased in vitro by CQ and slightly in vivo in nude mice. Conversely, CQ counteracted the Cur cytotoxic effect in immune competent mice, as demonstrated by the lack of in vivo tumor regression and the reduction of overall mice survival as compared with CUR-treated mice. Immunohistochemistry analysis revealed the presence of a remarkable FoxP3 T cell infiltrate within the tumors in CUR/CQ treated mice and a reduction of T cytotoxic cells, as compared with single CUR treatment. These findings suggest that autophagy is important to elicit anti-tumor immune response and that autophagy inhibition by CQ reduces such response also by recruiting T regulatory (Treg) cells in the tumor microenvironment that may be pro-tumorigenic and might counteract CUR-mediated anti-cancer effects.

Abstract: In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.

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: Resume Les donnees experimentales, epidemiologiques et cliniques suggerent que l’on puisse prevenir la survenue de cancer du sein chez la femme saine par prescription medicamenteuse, en particulier les anti-estrogenes. Cinq essais incluant plus de 25 000 femmes comparant l’efficacite du tamoxifene a un placebo, ont ete publies. Les resultats de ces essais, a premiere vue, ne concordent pas. L’essai de l’American National Surgical Adjuvant Breast and Bowel P-1 Project a tire au sort 13 000 femmes pour prescrire soit 20 mg de tamoxifene, soit un placebo. Une diminution du risque de survenue d’un cancer du sein de 49 % a ete objectivee. Cette reduction est associee a une diminution du risque de fractures, une augmentation du risque de cancers de l’endometre, de cataractes et d’accidents thrombœmboliques. Une analyse intermediaire de deux essais, l’un britannique (2500 femmes), l’autre italien (5000 femmes) n’a pas montre d’effet benefique sur le risque de cancer du sein. Un travail recent international objective une reduction du risque. Aucun de ces essais n’est assez puissant pour mettre en evidence une diminution de la mortalite due au cancer du sein. Ces etudes ne permettent pas de montrer clairement un benefice clinique de la prescription systematique de tamoxifene a toutes les femmes probablement en bonne sante, mais pour certaines femmes a risque le benefice pourrait surpasser les inconvenients des effets secondaires.

Abstract: A new precise measurement of |V_{cb}| and of the branching ratio BR(\bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell}) has been performed using a sample of about 5000 semileptonic decays \bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell}, selected by the DELPHI detector at LEP I by tagging the soft pion from D^{*+} -> D^0 \pi^+. The results are: V_{cb}=(39.0 +/- 1.5 (stat.) ^{+2.5}_{-2.6} (syst. exp.) +/- 1.3 (syst. th.)) x 10^{-3} BR(\bar{B^0} -> D^{*+} \ell^- \bar{\nu_\ell})=(4.70 +/- 0.13 (stat.) ^{+0.36}_{-0.31} (syst. exp.))% The analytic dependences of the differential cross-section and of the Isgur Wise form factor as functions of the variable w = v_{B^0}.v_{D^*} have also been obtained by unfolding the experimental resolution.

Abstract: Endometriosis is characterised by the presence of abnormally located tissue resembling the endometrium with glands and stroma. Several hypotheses have attempted to explain the development of such tissue. The oldest theory, that of metaplasia, suggests that under diverse influences coelomic tissue could be transformed into endometrium. The most often cited theory, that of implantation, proposes that the physiological phenomenon of endometrial reflux in the fallopian tubes during menstruation may, in certain conditions, overcome local defense mechanisms, implant, and proliferate. The peritoneal fluid in unaffected women possesses the capacity to prevent endometriotic tissue from becoming established. The reasons for the occurrence of endometriosis and its consequences (pain, sterility, adhesions) are probably numerous and involve the endometrium, the immune system (macrophages, natural killer cells), the peritoneum, and fallopian tubes. The failure to clear the peritoneal cavity of fragments of endometrium could cause a state of local inflammation with hyperactivation of macrophages secreting a variety of different compounds. Some of these compounds may bring about metaplasia of the peritoneum or the development of Mullerian residues.

Abstract: Searches for pair production of gauginos and squarks in e+e- collisions at a centre-of-mass energy of 189 GeV have been performed on data corresponding to an integrated luminosity of 158 pb^{-1} collected by the DELPHI detector at LEP. The data were analyzed under the assumption of non-conservation of R-parity through a single dominant Ubar Dbar Dbar coupling between squarks and quarks. Typical final states contain between 4 and 10 jets with or without additional leptons. No excess of data above Standard Model expectations was observed. The results were used to constrain domains of the MSSM parameter space and derive limits on the masses of supersymmetric particles. The following mass limits at 95% CL were obtained from these searches: neutralino mass: m_{\tilde{\chi^0_{1}}} \geq 32 GeV chargino mass: m_{\tilde{\chi^+_{1}}} \geq 94 GeV stop and sbottom mass (indirect decay) with \Delta M > 5 GeV: m_{\tilde{t_1}} \geq 74 GeV, for \Phi_{mix}=0 rad m_{\tilde{t_1}} \geq 59 GeV, for \Phi_{mix}=0.98 rad m_{\tilde{b_1}} \geq 72 GeV, for \Phi_{mix}=0 rad. The angle \phi_{mix} is the mixing angle between left and right handed quarks.

Abstract: A test of the QED process e+e- -> gamma gamma (gamma) is reported. The data analysed were collected with the DELPHI detector in 1998 and 1999 at the highest energies achieved at LEP, reaching 202 GeV in the centre-of-mass. The total integrated luminosity amounts to 375.7 pb^{-1}. The differential and total cross-sections for the process e+e- -> gamma gamma were measured, and found to be in agreement with the QED prediction. 95% Confidence Level (C.L.) lower limits on the QED cut-off parameters of Lambda+ > 330 GeV and Lambda- > 320 GeV were derived. A 95% C.L. lower bound on the mass of an excited electron of 311 GeV/c^2 (for lambda_gamma = 1) was obtained. s-channel virtual graviton exchange was searched for, resulting in 95% C.L. lower limits on the string mass scale, M_S: M_S > 713 GeV/c^2 (lambda = 1) and M_S > 691 GeV/c^2 (lambda = -1).

Abstract: The rapidity-rank structure of p pbar pairs is used to analyze the mechanism of baryon production in hadronic Z0 decay. The relative occurrence of the rapidity-ordered configuration p M pbar, where M is a meson, and that of p pbar adjacent pairs is compared. The data are found to be consistent with predictions from a mechanism producing adjacent-rank p pbar pairs, without requiring `string-ordered' p M pbar configurations. An upper limit of 15% at 90% confidence is determined for the p M pbar contribution.

Abstract: Searches for charginos, neutralinos and sleptons at LEP2 centre-of-mass energies from 130 GeV to 189 GeV have been used to set lower limits on the mass of the Lightest Supersymmetric Particle and other supersymmetric particles within the MSSM framework. R-parity conservation has been assumed. The lightest neutralino was found to be heavier than 32.3 GeV/c^2 independent of the m_0 value. The lightest chargino, the second-to-lightest neutralino, the next-to-heaviest neutralino, the heaviest neutralino, the sneutrino and the right-handed selectron were found to be heavier than 62.4 GeV/c^2, 62.4 GeV/c^2, 99.9 GeV/c^2, 116.0 GeV/c^2, 61.0 GeV/c^2, and 87.0 GeV/c^2, respectively. These limits do not depend on m_0 or M_2 and are valid for 1 \leq tan(beta) \leq 40, in the mu region where the lightest neutralino is the LSP. If the sneutrino is heavier than the chargino the lightest neutralino has to be heavier than 32.4 GeV/c^2. The effects of mixings in the third family of sfermions on these limits are discussed. The confidence level of all limits given is 95%.

Abstract: Searches for pair production of supersymmetric particles under the assumption that R-parity is not conserved are presented, based on data recorded by the DELPHI detector in 1998 from e+e- collisions at a centre-of-mass energy of 189 GeV. Only one R-parity violating LL\bar{E} term (i.e. one lambda coupling), which couples scalar leptons to leptons, is considered to be dominant at a time. Moreover, it is assumed that the strength of the R-parity violating couplings is such that the lifetimes can be neglected. The search for pair production of neutralinos, charginos and sleptons has been performed for both direct R-parity violating decays and indirect cascade decays. The results are in agreement with Standard Model expectations, and are used to update the constraints on the MSSM parameter values and the mass limits previously derived at sqrt(s) = 183 GeV. The present 95% C.L. limits on supersymmetric particle masses are: m_{\tilde{\chi}^0} > 30 GeV/c^2 and m_{\tilde{\chi}^\pm} > 94 GeV/c^2; m_{\tilde{\nu}} > 76.5 GeV/c^2 (direct and indirect decays); m_{\tilde{\ell}_R} > 83 GeV/c^2 (indirect decay only).

Abstract: The ratio of the CKM quark-mixing matrix elements |Vub|/|Vcb| has been measured using B hadron semileptonic decays. The analysis uses the reconstructed mass M_X of the secondary hadronic system produced in association with an identified lepton. Since B -> X_u lepton anti-nu transitions are characterised by hadronic masses below those of the D mesons produced in B -> X_c lepton anti-nu transitions, events with a reconstructed value of M_X significantly below the D mass are selected. Further signal enrichments are obtained using the topology of reconstructed decays and hadron identification. A fit to the numbers of decays in the b -> u enriched and depleted samples with M_X above and below 1.6 GeV/c^2 and to the shapes of the lepton energy distribution in the B rest frame gives |Vub|/|Vcb|= 0.103^{+0.011}_{-0.012} (stat.) +/- 0.016 (syst.) +/- 0.010 (model) and, correspondingly, a charmless semileptonic B decay branching fraction of BR(B -> X_u lepton anti-nu) = (1.57 +/- 0.35 (stat.) +/- 0.48 (syst.) +/- 0.27 (model)) x 10^{-3}., 24 pages, 8 figures

Abstract: A search for stable and long-lived heavy charged particles was performed using the data taken by the DELPHI experiment at an energy of 189 GeV. The Cherenkov light detected in the Ring Imaging Cherenkov Detector and the ionisation loss measured in the Time Projection Chamber were used to identify heavy particles passing through the detector. No evidence for the production of such particles has been found, therefore exclusion limits at 95% confidence level were derived on the masses of left and right handed smuons and staus. The results were combined with previous DELPHI searches in this channel. Including previous DELPHI results, masses of left (right) handed stable smuons and staus can be excluded between 2 GeV/c^2 and 88 (87.5) GeV/c^2 at 95% CL.

Abstract: An update of the searches for charginos and gravitinos is presented, based on a data sample corresponding to the 158 pb^{-1} recorded by the DELPHI detector in 1998, at a centre-of-mass energy of 189 GeV. No evidence for a signal was found. The lower mass limits are 4-5 GeV/c^2 higher than those obtained at a centre-of-mass energy of 183 GeV. The (\mu,M_2) MSSM domain excluded by combining the chargino searches with neutralino searches at the Z resonance implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 31.0 GeV/c^2 for tan(beta) \geq 1.

Abstract: A study of b semileptonic decays into D, D pi+- and D* pi+- final states is presented. The D0, D+ and D*+ mesons are exclusively reconstructed in Z decay data recorded from 1992 to 1995 in the DELPHI experiment at LEP. The overall branching fractions are measured to be: BR(b -> D^0 \ell^- \bar{\nu}_{\ell} X) = (7.04 +/- 0.34 (stat) +/- 0.36 (syst.exp) +/- 0.17 (BR_D))% BR(b -> D^+ \ell^- \bar{\nu}_{\ell} X) = (2.72 +/- 0.19 (stat) +/- 0.16 (syst.exp) +/- 0.18 (BR_D))% BR(b -> D^{*+} \ell^- \bar{\nu}_{\ell} X) = (2.75 +/- 0.17 (stat) +/- 0.13 (syst.exp) +/- 0.09 (BR_D))% where the D0 and D+ results include also contributions from D*0 and D*+ decays. A fit to the distribution of the pi+- impact parameter to the primary interaction vertex provides a measurement of the b semileptonic branching fractions into the D0 pi+- X, D+ pi+- X and D*+ pi+- X final states. Assuming that single pion decay modes of B mesons dominate, the partial rates for \bar{B} -> D \pi \ell^- \bar{\nu_{\ell}} and \bar{B} -> D^{*} \pi \ell^- \bar{\nu_{\ell}} have been obtained, corresponding to a total branching fraction: BR(\bar{B} -> D \pi \ell^- \bar{\nu_{\ell}}) + BR(\bar{B} -> D^{*} \pi \ell^- \bar{\nu_{\ell}}) = (3.40 +/- 0.52 (stat) +/- 0.32 (syst))% . This result agrees well with the observed difference between the total B semileptonic branching fraction and the sum of the \bar{B} -> D \ell^- \bar{\nu_{\ell}} and D^* \ell^- \bar{\nu_{\ell}} branching fractions.

Abstract: The longitudinal polarization of the Λb baryon is measured at the LEP e+e− collider by DELPHI. It is determined from the charged lepton and neutrino energy spectra in 249±19 Λb semileptonic decays reconstructed in ≈3.5 million hadronic Z0 decays using Λ0-lepton correlations. The measured polarization is: PΛb=−0.49−0.30+0.32(stat.)±0.17(syst.)

Abstract: Promptly decaying lightest charginos were searched for in the context of scenarios with gravitino LSP. It was assumed that the stau is the next to lightest supersymmetric particle (NLSP). Data collected with the DELPHI detector at a centre-of-mass energy near 183~{~mbox{${mathrm{GeV}}$}}\nwere analysed combining the methods developed in previous searches. No evidence for the production of these particles was found. Hence, limits were derived at 95% confidence level. The mass of charginos was found to be greater than 85.5~GeV/$c^2$ for $m_{ ilde{chi}^+_1}-m_{ ilde{ au}_1}geq 0.3 {mathrm{GeV}}/c^2$, independently of the mass of the gravitino.

Abstract: The rate $Z \rightarrow b\overline{b}b\overline{b}$ was measured using about $2 x 10^6$ hadronic decays collected by the DELPHI experiment in 1994 and 1995. Events were forced into 3-jets with $y_{min} 0.06$ and a b-tag was required for every jet. The rate was measured to be: $R_{4b} = BR(Z \to b\overline{b}b\overline{b}) / BR(Z \to hadrons) = (6.0 +- 1.9(stat) +- 1.4(syst.)) x 10^{-4}$ where the invariant mass of every $b\overline{b}$ system is above twice the b quark mass. Using the value of $R_{4b}$ the probability of secondary production of a $b\overline{b}$ pair from a gluon per hadronic $Z$ decay, $g_{bb}$, was extracted and found to be: $g_{bb} = (3.3+-1.0(stat.) +- 0.8(syst.)) x 10^{-3}$.

Abstract: DELPHI results are presented on the inclusive production of the neutral mesons ρ0, f0(980), f2(1270), KView the MathML source and f′2(1525) in hadronic Z0 decays. They are based on about 2 million multihadronic events collected in 1994 and 1995, using the particle identification capabilities of the DELPHI Ring Imaging Cherenkov detectors and measured ionization losses in the Time Projection Chamber. The total production rates per hadronic Z0 decay have been determined to be: 1.19±0.10 for ρ0; 0.164±0.021 for f0(980); 0.214±0.038 for f2(1270); 0.073±0.023 for KView the MathML source; and 0.012±0.006 for f′2(1525). The total production rates for all mesons and differential cross-sections for the ρ0, f0(980) and f2(1270) are compared with the results of other LEP experiments and with models.

Abstract: A search for events with one jet and at most one isolated lepton used data taken at LEP-2 by the DELPHI detector.These data were accumulated at a center-of-mass energy of 183 GeV and correspond to an integrated luminosity of 47.7 1/pb. Production of single scalar and vector leptoquarks was searched for. Limits at 95% confidence level were derived on the masses (ranging from $134 GeV/c^2$ to $171 GeV/c^2$ for electromagnetic type couplings) and couplings of the leptoquark states.A search for top-charm flavour changing neutral currents($e^+ e^- \to \bar t c$ or charge conjugate) used the semileptonic decay channel. A limit on the flavour changing cross-section via neutral currents was set at 0.55pb (95% confidence level).

Abstract: An update of the searches for charginos and neutralinos is presented, based on a data sample corresponding to the 53.9 pb−1 recorded by the DELPHI detector in 1997, at a centre-of-mass energy of 183 GeV. No evidence for a signal was found. The lower mass limits are 4–5 GeV/c2 higher than those obtained at a centre-of-mass energy of 172 GeV. The (μ,M2) domain excluded by combining the neutralino and chargino searches implies a limit on the mass of the lightest neutralino which, for a heavy sneutrino, is constrained to be above 29.1 GeV/c2 for tanβ≥ 1.

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 novel technique for detecting minimum ionising particles (i.e. m.i.p.) was designed and a first prototype fabricated in a standard CMOS technology, guided by very high vertex detector performances required in future collider experiments. The device architecture resembles CMOS cameras, a recent alternative to CCD sensors for visible light imaging. The performance of the first prototype was evaluated with high energy π − beams at CERN. Preliminary test results demonstrate that the sensors detect m.i.p.s with very high efficiency and signal-to-noise ratio and provide excellent surface resolution.

Abstract: A 36-year-old para 5 patient, was hospitalized in our obstetric department for moderate jaundice associated with vomiting at 8 weeks of gestation. Vomiting appeared 3 weeks before, followed 10 days after by jaundice associated with pain in the right hypochondrium. The four previous pregnancies unfolded without any particularity. This patient had no medical or surgical history. When admitted to hospital, the patient complained of abundant vomiting occurring for 3 weeks. The Ž exam confirmed the jaundice especially conjunc. tival . The abdominal palpation diagnosed an hepatomegaly associated with a sensibility of the right hypochondrium. Moreover the patient signaled colored urine confirming the retentional character of this jaundice. The exam also indiŽ cated an important wasting away 7% of the total . weight . Questioning neither revealed recent travel, nor a recent absorption of medicinal dose, or a recent infectious disease. The biological check-up showed: serum alanine aminotransferase 550 IUrl; serum conjugated bilirubin 106

Abstract: Recent advances in therapeutics have considerably modified the management of ectopic pregnancy. However, surgical management is still indicated in some patients. Laparoscopic procedure is the reference surgical approach for the management of ectopic pregnancy. It reduces length of hospital stay, analgesic requirement, hospital cost, the risk of post-surgical adherence and is also associated with lower morbidity and better esthetic appearance. Laparotomy is now only performed in individuals for whom laparoscopy is contra-indicated. Patients can be treated conservatively, tubotomy with removal of the products of conception or radically, salpingectomy. In order to lower the failure rate and the risk of re-occurrence, some operative procedures are required including regular washing of the abdominal cavity, adhesiolysis and extraction in a protective bag. The choice of treatment is generally guided by the patient's past medical history and the wish to bear future children.

Abstract: Description and evaluation of ligamentopexy techniques using strings and spiral staples.We first describe the ligamentopexy procedure using non-absorbable sutures before comparing this technique to the use of Tacker type staples. We describe the advantages and disadvantages of this procedure in terms of surgical technique, secondary complications and biomechanical strength.For our team, recommendable attitude is to use non-absorbable sutures for the fixation to the prevertebral ligament. The main advantages of the use of staples are the ease and facility for learning the technique. The risk of spondylodiscitis is rare but enhanced by the deeper penetration of the staples into the intervertebral discs. In terms of resistanc, promontofixation using sutures is much stronger compared to staples.The use of sutures for promontofixation, in laparoscopy, is preferred to the utilization of staples type Tacker. These staples should be used when there is a risk of needle stitches for the patient.

Abstract: Breast cancer is certainly not preventable at the same degree as lung cancer is by avoiding cigarette smoking or bladder cancer by avoiding exposure to some specific professional carcinogens. Despite the increased availability of screening mammography and the use of adjuvant chemotherapy, breast cancer remains a major cause of morbidity and mortality in women. Chemoprevention could be one of the possible weapons to decrease the morbidity and the mortality due to breast cancer. Experimental, epidemiological and clinical data suggest that one can prevent occurrence of breast cancer. The results of five trials including more than 25,000 patients comparing the effectiveness of tamoxifen with a placebo were published. The results of these trials, at first sight, do not agree. Only in the USA, the results of the five trials have led to licence tamoxifen for chemoprevention of breast cancer. But the Food and Drug Administration stresses the fact that the noxious side effects are too numerous for this molecule to be prescribed with all the patients. It must be reserved for the women presenting an increased risk. The means of identifying the women at increased risk are not yet perfect.

Abstract: A monolithic active pixel sensor (MAPS) for charged particle tracking based on a novel detector structure was proposed, simulated, fabricated and tested. The detector designed accordingly to this idea is inseparable from the readout electronics, since both of them are integrated onto the same, standard for a CMOS process, low-resistivity silicon wafer. The individual pixel is comprised of only 3 MOS transistors and a photodiode collecting the charge created in a thin undepleted epitaxial layer. This approach provides the whole detector surface sensitive to radiation (100% fill factor) with reduced pixel pitch(very high spatial resolution). This yields a low cost, high resolution and thin detecting device. The detailed device simulations using an ISE-TCAD package have been carried out in order to study a charge collection mechanism and to validate the proposed idea. Consequently, two prototype chips have been fabricated using 0.6 /spl mu/m and 0.35 /spl mu/m CMOS processes. Special radiation tolerant layout techniques were used in the second chip design. Both chips were tested and fully characterised. The pixel conversion gain was calibrated using 5.9 keV photons and prototype devices were exposed to the 120 GeV/c pion beams at CERN. Obtained results preceded by general design ideas and simulation results are reviewed.

Abstract: Heat-shock protein (HSP) 70 is aberrantly expressed in different malignancies and has a cancer-specific cell-protective effect. As such, it has emerged as a promising target for anticancer therapy. In this study, the effect of the HSP70-specific inhibitor (PES), also Pifitrin-μ, on primary effusion lymphoma (PEL) cell viability was analyzed. PES treatment induced a dose- and time-dependent cytotoxic effect in BC3 and BCBL1 PEL cells by inducing lysosome membrane permeabilization, relocation of cathepsin D in the cytosol, Bid cleavage, mitochondrial depolarization with release and nuclear translocation of apoptosis-activating factor. The PES-induced cell death in PEL cells was characterized by the appearance of Annexin-V/propidium iodide double-positive cells from the early times of treatment, indicating the occurrence of an additional type of cell death other than apoptosis, which, accordingly, was not efficiently prevented by the pan-caspase inhibitor Z-VAD-fmk. Conversely, PES-induced cell death was robustly reduced by pepstatin A, which inhibits Bid and caspase 8 processing. In addition, PES was responsible for a block of the autophagic process in PEL cells. Finally, we found that PES-induced cell death has immunogenic potential being able to induce dendritic cell activation.

Abstract: A novel monolithic active pixel sensor for charged particle tracking has been designed and fabricated in a standard CMOS technology. The device architecture is identical to a CMOS camera, recently being proposed as an alternative to CCD sensors for visible light imaging. The partially depleted thin epitaxial silicon layer is used as a sensitive detector volume. The sensor is a photodiode having a special structure, which allows the high detection efficiency required for tracking applications A first prototype was made of four arrays each containing 64×64 pixels, with a readout pitch of 20 μm in both directions. An architecture allowing serial readout of the analogue information from each pixel has been implemented. To evaluate the tracking performance of such a device, series of tests have been performed using a high-energy particle beam. A detailed analysis of the beam test data presented in this work demonstrate close to 100% minimum ionising particle detection efficiency and a good enough signal-to-noise ratio of more than 30.

38. Activation of p53/p21waf1 pathway is associated with senescence during v-Ha-ras transformation of immortal C2C12 myoblasts

Abstract: It has recently been shown that tumor cells can retain the ability to undergo senescence, while the capacity of bypassing senescence has been associated with tumor progression. In this report, we showed that v-Ha-ras-mediated transformation of already immortal C2C12 myoblasts can be associated with senesence, in a low amount during in vitro passages and, to a higher extent, affer cellular stress (cell culture alkalinkation), or DNA damage (doxorubicin treatment). The capacity to undergo replicative senescence is associated with a strong increase of wt-p53 transcriptional activity and p21WAF1 up-regulation. These biochemical activities are down-modulated in the cells that evade the massive replicative senescence after stressing stimuli. Altogether, these findings show that active ras can cause senescence during the transformation of already immortal cells in associaton with p53/p21WAF1 pathway activation and support the hypothesis that p53/p21WAF1 functional activity is important in maintaining the integrity of the senescence pathway during cellular transformation.

Abstract: The DELPHI detector at LEP has collected 54 pb^{-1} of data at a centre-of-mass energy around 183 GeV during 1997, 158 pb^{-1} around 189 GeV during 1998, and 187 pb^{-1} between 192 and 200 GeV during 1999. These data were used to measure the average charged particle multiplicity in e+e- -> b bbar events, _{bb}, and the difference delta_{bl} between _{bb} and the multiplicity, _{ll}, in generic light quark (u,d,s) events: delta_{bl}(183 GeV) = 4.55 +/- 1.31 (stat) +/- 0.73 (syst) delta_{bl}(189 GeV) = 4.43 +/- 0.85 (stat) +/- 0.61 (syst) delta_{bl}(200 GeV) = 3.39 +/- 0.89 (stat) +/- 1.01 (syst). This result is consistent with QCD predictions, while it is inconsistent with calculations assuming that the multiplicity accompanying the decay of a heavy quark is independent of the mass of the quark itself.

Abstract: Searches for HZ production with the Higgs boson decaying into an invisible final state have been performed with the data collected by the DELPHI experiment up to the centre-of-mass energy of 183 GeV. The hadronic and muon pair final states of the Z boson were analysed. From the absence of signal, upper limits on the cross-section and the corresponding Higgs boson mass limits were set at 95% confidence level. The results are interpreted as excluded parameter regions in the framework of the minimal supersymmetric standard model and in the simplest Majoron model with one Higgs doublet and one Higgs singlet field.

Abstract: Measurements of the trilinear gauge boson couplings WWγ and WWZ are presented from data taken by DELPHI in 1997 at an energy of 183 GeV. From a study of the reactions e + e − → W + W − , e + e − → Weν and e + e − → ννγ , values are obtained for Δg 1 Z and Δκ γ , the differences of the WWZ charge coupling and of the WWγ dipole couplings from their Standard Model values, and for λ γ , the WWγ quadrupole coupling. The observations are consistent with the predictions of the Standard Model. (Elsevier)

Abstract: Infrared and collinear safe event shape distributions and their mean values are determined using the data taken at five different centre of mass energies above M-Z with the DELPHI detector at LEP. From the event shapes, the strong coupling alpha(s) is extracted in O(alpha(s)(2)), NLLA and a combined scheme using hadronisation corrections evaluated with fragmentation model generators as well as using an analytical power ansatz. Comparing these measurements to those obtained at M-Z, the energy dependence (running) of alpha(s) is accessible. The logarithmic energy slope of the inverse strong coupling is measured to be d alpha(s)(-1)/d log(E-cm) = 1.39 +/- 0.34 (stat) +/- 0.17(syst), in good agreement with the QCD expectation of 1.27.

Abstract: The events with two photons and missing (transverse) energy collected by the DELPHI detector at centre-of-mass energies between 130~GeV and 183~GeV have been studied to search for processes of the type $\mbox{e}^+\mbox{e}^- \to \mbox{Y} \mbox{Y}$ with the subsequent decay $\mbox{Y} \to \mbox{X} \gamma$, where X is an undetectable neutral particle. Reactions of this kind are expected in supersymmetric models, where the Y particle can be either the lightest neutralino, decaying to a photon and a gravitino, or the next-to-lightest neutralino, decaying to a photon and the lightest neutralino. To study the case of long-lived Y particles, a search for single-photon events with the reconstructed photon axis pointing far from the beam interaction region has also been performed. No evidence for a deviation from Standard Model expectations has been observed in the data and upper limits have been derived on the signal cross-section as a function of the the X and Y masses and of the Y mean decay path.

Abstract: This paper presents results on charged Higgs boson production, based on LEP data collected at √s = 172 GeV, that complement the previous DELPHI results obtained at centre of mass energies up to 161 GeV. The charged Higgs bosons are assumed to be pair produced and to decay either into a quark pair or into τVτ. The three different possible final states are included in the analysis. Data from ring imaging Cherenkov and microvertex detectors are used to identify the quarks as a cs pair. The number of candidates found is compatible with the background expected from standard processes. Combining the results of the present analysis with those of the previous analysis at lower energies, a new lower mass limit for the charged Higgs boson is set at 54.5 GeV/c2. © 1998 Elsevier Science B.V.

Abstract: The value of the b quark mass at the M Z scale defined in the MS renormalization scheme, m b ( M Z ), was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m b (M Z )=2.67±0.25 ( stat. )±0.34 ( frag. )±0.27 ( theo. ) GeV/c 2 . The analysis considers NLO corrections to the three-jet production rate including mass effects, and the result obtained agrees with the QCD prediction of having a running b quark mass at an energy scale equal to M Z . This is the first time that such a measurement is performed far above the b b production threshold. The study also verifies the flavour independence of the strong coupling constant for b and light quarks within 1% accuracy.

Abstract: The data collected by DELPHI in 1996 have been used to measure the average charged particle multiplicities and dispersions in $q\bar{q}$ events at centre-of-mass energies of $\sqrt{s}=161$~GeV and $\sqrt{s}=172$~GeV, and the average charge multiplicity in WW events at $\sqrt{s}=172$~GeV. The multiplicities in $q\bar{q}$ events are consistent with the evolution predicted by QCD. The dispersions in the multiplicity distributions are consistent with Koba-Nielsen-Olesen (KNO) scaling. The average multiplicity of charged particles in hadronic W decays has been measured for the first time; its value, $19.23 \pm 0.74 (stat+syst)$, is consistent with that expected for an $e^+e^-$ interaction at a centre-of-mass energy equal to the W mass. The charged particle multiplicity in W decays shows no evidence of effects of colour reconnection between partons from different W's at the present level of statistics.

Abstract: Trilinear gauge boson couplings are measured using data taken by DELPHI at 161 GeV and 172 GeV, Values for WWV couplings (V = Z,gamma) are determined from a study of the reactions e(+)e(-) --> W+W- and e(+)e(-) --> We nu, using differential distributions from the WW final state in which one W decays hadronically and the other leptonically, and total cross,section data from other channels, Limits are also derived on neutral ZV gamma couplings from an analysis of the reaction e(+)e(-) --> gamma + invisible particles.

Abstract: In an analysis of multihadronic events recorded at LEP by DELPHI in the years 1992 through 1994, charged hadrons are identified using the measurement of their energy loss and their Cherenkov angle. Rapidity correlations of \La-\La, proton-proton, and \La-proton pairs are compared. The agreement with the string and cluster fragmentation models is tested. For those pairs that frame a meson in terms of rapidity the compensation of strangeness is studied. For \La{}$\overline{\mathrm{p}}$ pairs the additional correlation with respect to charged kaons is analysed.
