Background. Chronic alcohol abuse is associated with a wide range of cognitive deficits. However, little is known about memory for real-life events (autobiographical memory) in non-amnesic alcoholic patients. The purpose of this study was to investigate (a) non-amnesic alcoholics' ability to recall specific autobiographical memories and (b) their subjective experience when they access specific memories.Method. Twenty non-amnesic (without Korsakoff syndrome) recently detoxified alcoholics and 20 healthy controls completed the Autobiographical Memory Test (AMT), which assesses the frequency of specific (versus general) memories recalled in response to cue words, and the Memory Characteristics Questionnaire (MCQ), which assesses subjective experience (e.g. the amount of sensory and contextual details experienced) when remembering specific events.Results. Alcoholic patients recalled specific memories less frequently and general memories more frequently than healthy controls. Nevertheless, when a specific past event was accessed, alcoholic patients subjectively experienced as many sensory and contextual details as controls.Conclusions. These findings suggest that non-amnesic alcoholics have difficulties strategically accessing event-specific autobiographical knowledge, which might result from changes in frontal lobe function that are associated with alcoholism.

Numerous studies suggest a cognitive bias for threat-related material in delusional ideation. However, few studies have examined this bias using a memory task. We investigated the influence of delusion-proneness on identity and expression memory for angry and happy faces. Participants high and low in delusion-proneness were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been. Remember/know/guess judgments were asked for both identity and expression memory. Results showed that delusion-prone participants better recognised the identity of angry faces compared to non-delusional participants. Also, this difference between the two groups was mainly due to a greater number of remember responses in delusion-prone participants. These findings extend previous studies by showing that delusions are associated with a memory bias for threat-related stimuli. [less ▲]

The aim of concrete surface preparation prior to repair is to obtain a surface with properties close to that of the bulk concrete. In this paper, the results of an investigation intended to evaluate the mechanical degradation induced by different surface preparation techniques are presented. Optical microscope observations clearly show that more cracking is induced with jack-hammers than with the other investigated techniques and that the cracking density increases with the hammer weight. While more information is needed to evaluate quantitatively the effects of concrete removal operations, it appears from the reported results that techniques such as sandblasting, scarifying and water jetting are preferable, as they clearly leave much less defects in the substrate.

Nowadays, the management of ectopic pregnancy should be codified as often as possible. Two types of treatment are possible. One surgical and the other medical. Our study is concerned with a series of 97 patients hospitalized for suspicion of ectopic pregnancy for whom the risk factors and treatment were analyzed. Our conclusion is that the medical treatment should be more frequently proposed and surgery should prefer the conservative treatment whenever it is still possible. [less ▲]

Background: The aim of this study was to analyze the use of magnetic resonance imaging (MRI) as a modern medical imaging technique in radiotherapy with special emphasis on the integration of MRI and a novel technique in brachytherapy to optimize treatment outcome in cervical cancer. Methods: In addition to the CT based shrinking volume conformal teletherapy in 31 patients with locally advanced cervical cancer, MRI examination with a special adjustable applicator at the treatment site was performed for the brachytherapy planning. To avoid excessive doses to the healthy structures during complex cervical radiotherapy isodose curves were calculated upon the information of the MR image and dose distribution was evaluated. Results: The consecutive application of CT and MRI limited the possibility for overdosage of the critical organs and undertreatment of the advanced tumor spread in all cases. The overall response rate for the complex treatment was 74.2% with complete regression in 25.8% of the cases. Based on the exact information of the three dimensional digital data radiation doses could be optimized without increasing the possibility of acute complications rate. Conclusion: The introduction of 3D treatment planning for teletherapy pelvic and boost irradiation of cervical carcinoma as well as for the brachytherapy part of the complex treatment is to be recommended.

A study is presented on the crystallization of ornithine acetyltransferase from yeast, which catalyzes the fifth step in microbial arginine synthesis. The use of the counter-diffusion technique removes the disorder present in one dimension in crystals grown by either the batch or hanging-drop techniques. This makes the difference between useless crystals and crystals that allow successful determination of the structure of the protein. The crystals belong to space group P4, with unit-cell parameters a = b = 66.98, c = 427.09 angstrom, and a data set was collected to 2.76 angstrom. [less ▲]

We propose a multi-dimensional strategy, associating immunodetection to a protein fractionating two-dimensional liquid chromatography tool, for serological characterization of microbial antigens. The originality of such immunoproteomic approaches resides in their application in large-scale studies for rapid serotyping of micro-organisms, evaluation of immunomes and could be proposed in the development and monitoring of vaccines.

Background. The spectral entropy of the electroencephalogram has been proposed to monitor the depth of anaesthesia. State Entropy (SE) reflects the level of hypnosis. Response Entropy (RE), computed from electroencephalogram and facial muscle activity, reflects the response to nociceptive stimulation. We evaluated the effect of rocuronium on Bispectral Index (TM) (BIS) and entropy responses to laryngoscopy. Methods. A total of 25 patients were anaesthetized with propofol using a target-controlled infusion. At steady state, they randomly received 0.6 mg kg(-1) rocuronium (R) or saline (S). After 3 min, a 20 s laryngoscopy was applied. BIS, RE and SE were recorded continuously and averaged over 1 min during baseline, at steady state, 2 min after R or S administration (R/S+2) and 0, 1, 2 and 3 min after laryngoscopy (L0, L1, L2, L3). Results. At R/S+2, the RE-SE gradient was higher in Group S than in Group R. Laryngoscopy provoked an increase in BIS, RE and SE. Comparing R/S+2 and L0 values in Groups R and S, BIS increased from 43 (6) to 49 (8) and 42 (9) to 51 (15), SE increased from 43 (7) to 50 (8) and 41 (10) to 55 (12), and RE increased from 46 (8) to 54 (9) and 47 (12) to 66 (15), respectively. BIS and SE did not differ between groups. At L0, RE and RE-SE were higher in Group S [66 (15) and 11 (4), respectively] than in Group R [54 (9) and 4 (2), respectively]. Conclusions. Rocuronium alters the RE-SE gradient and the RE and RE-SE responses to laryngoscopy. Muscle relaxation may confound interpretation of entropy monitoring. [less ▲]

Les changements causés par le vieillissement se déroulent à un rythme différent pour chaque personne et dépendent de facteurs comme le style de vie, les activités et l'environnement ainsi que des facteurs comme le bagage génétique et l'état de santé.La presbyphonie est le terme employé pour définir le vieillissement de la voix. Elle s'observe le plus souvent après 60 ans et touche les deux sexes. Ce trouble vocal est la conséquence d'altérations morphologiques et fonctionnelles des systèmes pneumo-phono-articulatoires qui résultent d'une modification hormonale (thyroïdienne et sexuelles), d'une altération de l'état musculaire, vasculaire, nerveux ou respiratoire, ou encore d'un manque d'exercice vocal.

The smallness of the observed neutrino masses might have a radiative origin. Here we revisit a specific two-loop model of neutrino mass, independently proposed by Babu and Zee. We point out that current constraints from neutrino data can be used to derive strict lower limits on the branching ratio of flavour changing charged lepton decays, such as μ→eγ. Non-observation of Br(μ→eγ) at the level of 10^(−13) would rule out singly charged scalar masses smaller than 590 GeV (5.04 TeV) in case of normal (inverse) neutrino mass hierarchy. Conversely, decay branching ratios of the non-standard scalars of the model can be fixed by the measured neutrino angles (and mass scale). Thus, if the scalars of the model are light enough to be produced at the LHC or ILC, measuring their decay properties would serve as a direct test of the model as the origin of neutrino masses.

Successful embryo development requires an extensive endometrial angiogenesis in proximity of implantation site. The glycoprotein hCG is produced even before implantation by trophoblast in normal pregnancy. In this manuscript, we demonstrate an angiogenic effect of hCG in several in vivo (chick chorioallantoic membrane, matrigel plug assay, aortic ring assay) and in vitro experimental models. In contrast, human placental lactogen (hPL) did not display angiogenic properties. LH/hCG receptor was detected in endothelial cells by reverse-transcriptase polymerase chain reaction (RT-PCR) and by Western blotting. In mice aortic ring assay, angiostimulation by hCG was abrogated by deletion of LH/hCG receptor (LuRKO mice). Use of recombinant hCG and anti-hCG antibody (Ab) further confirmed the specificity of this angiogenic activity. By using dibutyryl cAMP, adenylate cyclase, or protein kinase A inhibitors, we demonstrate that hCG-mediated angiogenesis involves adenylyl-cyclase-protein kinase A activation. Addition of hCG to endometrial epithelial epithelial cells, but not to cultured endothelial cells, stimulated vascular endothelial growth factor (VEGF). VEGF and hCG also displayed additive activities. Altogether, these data demonstrate that peritrophoblastic angiostimulation may result from a paracrine dialogue between trophoblast, epithelial, and endothelial cells through hCG and VEGF. [less ▲]
