Toward a comparative analysis of coming and going verbs in Spanish, German, and Polish

This work deals with coming and going verbs in three typologically distinct languages: a Romance one (Spanish), a Germanic one (German) and a Slavic one (Polish) within Fillmore`s (1966, 1971, 1975, 1982, 1983) framework. On the grounds of data description it is shown that visible linguistic phenomena, such as deixis or Aktionsart related clearly to the coming and going verbs, can be transcended, resorting to the more abstract notion called by the author, following Winston (1987) and Speas and Tenny (2003), “viewpoint”.

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease. 1 - Comparative xenodiagnosis with nine triatomine species of animals with acute infections by Trypanosoma cruzi

In search of a suitable vector species for xenodiagnosis of humans and animals with chronic Chagas' disease we first investigated the reactions of different vector species to acute infection with Trypanosoma cruzi. Vector species utilized in this study were: Triatoma infestans, Rhodnius prolixus and Triatoma dimidiata, all well adapted to human habitats; Triatoma rubrovaria and Rhodnius neglectus both considered totally wild species; Panstrongylus megistus, Triatoma sordida, Triatoma pseudomaculata and Triatoma brasiliensis, all essentially sylvatic but some with domiciliary tendencies and others restricted to peridomestic biotopes with incipient colonization of human houses after successful eradication of T. infestans. Results summarized in Table IV suggest the following order of infectivity among the 9 studied vector species: P. megistus with 97.8% of infected bugs, T. rubrovaria with 95% of positive bugs a close second followed by T. Pseudomaculata with 94.3% and R. neglectus with 93.8% of infected bugs, almost identical thirds. R. prolixus, T. infestans and T. dimidiata exhibited low infection rates of 53.1%, 51.6% and 38.2% respectively, coupled with sharp decreases occuring with aging of infection (Fig. 1). The situation was intermediate in T. brasiliensis and T. sordida infection rates being 76.9% and 80% respectively. Results also point to the existence of a close correlation between prevalence and intensity of infection in that, species with high infection rates ranging from 93.8% to 97.8% exhibited relatively large proportions of insects (27.3% - 33.5%) harbouring very dense populations of T. cruzi. In species with low infection rates ranging from 38.2% to 53.1% the proportion of bugs demonstrating comparable parasite densities was at most 6%. No differences attributable to blood-meal size or to greater susceptibility of indigenous vector species to parasites of their own geographical area, as suggested in earlier...

Competitive interactions between species of freshwater snails. I. Laboratory studies: Ib. Comparative studies of the dispersal and the vagility capabilities of Biomphalaria glabrata and Biomphalaria straminea

Experiments reported in the current paper, carried out under semi-field conditions created in the laboratory, have shown that b. straminea has competitive superiority when compared with B. glabrata. The former species has shown higher capabilities of both dispersal and vagility. In addition, B. straminea was able to compete sucessfully with B. glabrata.

Competitive interactions between species of fresh-water snails: I. Laboratory. IC. Comparative survival of Biomphalaria glabrata and B. Straminea kept out of water

Biomphalaria glabrata and B. straminea were submitted to an out-door laboratory experiment for testing their comparative ability to resist desiccation. Results have shown that B. straminea is significantly higher resistant than B. glabrata. After five months under such distressing condition the survival ratios were: B. glabrata 8.1 per cent and B. straminea 18.4 per cent.

Non-assisted versus neuro-navigated and XperCT-guided external ventricular catheter placement: a comparative cadaver study.

BACKGROUND AND PURPOSE: Accurate placement of an external ventricular drain (EVD) for the treatment of hydrocephalus is of paramount importance for its functionality and in order to minimize morbidity and complications. The aim of this study was to compare two different drain insertion assistance tools with the traditional free-hand anatomical landmark method, and to measure efficacy, safety and precision. METHODS: Ten cadaver heads were prepared by opening large bone windows centered on Kocher's points on both sides. Nineteen physicians, divided in two groups (trainees and board certified neurosurgeons) performed EVD insertions. The target for the ventricular drain tip was the ipsilateral foramen of Monro. Each participant inserted the external ventricular catheter in three different ways: 1) free-hand by anatomical landmarks, 2) neuronavigation-assisted (NN), and 3) XperCT-guided (XCT). The number of ventricular hits and dangerous trajectories; time to proceed; radiation exposure of patients and physicians; distance of the catheter tip to target and size of deviations projected in the orthogonal plans were measured and compared. RESULTS: Insertion using XCT increased the probability of ventricular puncture from 69.2 to 90.2 % (p = 0.02). Non-assisted placements were significantly less precise (catheter tip to target distance 14.3 ± 7.4 mm versus 9.6 ± 7.2 mm, p = 0.0003). The insertion time to proceed increased from 3.04 ± 2.06 min. to 7.3 ± 3.6 min. (p < 0.001). The X-ray exposure for XCT was 32.23 mSv, but could be reduced to 13.9 mSv if patients were initially imaged in the hybrid-operating suite. No supplementary radiation exposure is needed for NN if patients are imaged according to a navigation protocol initially. CONCLUSION: This ex vivo study demonstrates a significantly improved accuracy and safety using either NN or XCT-assisted methods. Therefore, efforts should be undertaken to implement these new technologies into daily clinical practice. However, the accuracy versus urgency of an EVD placement has to be balanced, as the image-guided insertion technique will implicate a longer preparation time due to a specific image acquisition and trajectory planning.

Comparative ELISA reagents for detection of hepatitis B surface antigen (HBsAg)

Conjugates of goat anti-HBs IgG and horseradish peroxidase (HRP) prepared by two different methods, one using NaIO4 and the other SPDP, were compared. Anti-HBs antibodies obtained from goat, rabbit and guinea-pig were tested as capture serum. The ELISA showed a sensitivity similar to RIA and a level of antigen captation ranging from 4.37 to 8.75 nanograms/ml was obtained when rabbit or guinea-pig captures were used combined with both NaIO4 or SPDP conjugates.

Photodynamic therapy with mTHPC and polyethylene glycol-derived mTHPC: a comparative study on human tumour xenografts.

The photosensitizing properties of m-tetrahydroxyphenylchlorin (mTHPC) and polyethylene glycol-derivatized mTHPC (pegylated mTHPC) were compared in nude mice bearing human malignant mesothelioma, squamous cell carcinoma and adenocarcinoma xenografts. Laser light (20 J/cm2) at 652 nm was delivered to the tumour (surface irradiance) and to an equal-sized area of the hind leg of the animals after i.p. administration of 0.1 mg/kg body weight mTHPC and an equimolar dose of pegylated mTHPC, respectively. The extent of tumour necrosis and normal tissue injury was assessed by histology. Both mTHPC and pegylated mTHPC catalyse photosensitized necrosis in mesothelioma xenografts at drug-light intervals of 1-4 days. The onset of action of pegylated mTHPC seemed slower but significantly exceeds that of mTHPC by days 3 and 4 with the greatest difference being noted at day 4. Pegylated mTHPC also induced significantly larger photonecrosis than mTHPC in squamous cell xenografts but not in adenocarcinoma at day 4, where mTHPC showed greatest activity. The degree of necrosis induced by pegylated mTHPC was the same for all three xenografts. mTHPC led to necrosis of skin and underlying muscle at a drug-light interval of 1 day but minor histological changes only at drug-light intervals from 2-4 days. In contrast, pegylated mTHPC did not result in histologically detectable changes in normal tissues under the same treatment conditions at any drug-light interval assessed. In this study, pegylated mTHPC had advantages as a photosensitizer compared to mTHPC. Tissue concentrations of mTHPC and pegylated mTHPC were measured by high-performance liquid chromatography in non-irradiated animals 4 days after administration. There was no significant difference in tumour uptake between the two sensitizers in mesothelioma, adenocarcinoma and squamous cell carcinoma xenografts. Tissue concentration measurements were of limited use for predicting photosensitization in this model.

Substance use and depression. Comparative course in adolescents.

OBJECTIVE: To examine the relation between depression and substance use in adolescents and the concomitant courses of both disorders. METHODS: Four individual interviews were administered to 85 adolescent substance users aged 14-19 years (mean 17.1 years, SD 1.4) over a 3.5 year period using the Adolescent Drug Abuse Interview (ADAD) and the Beck Depression Inventory (BDI-13). RESULTS: No predictive effect was observed on one dimension over the other, but each dimension was predictive of its own course. A decrease in substance-use severity paralleled a decrease in depressive state. Similarly, stable substance-use rates, either at a low or a high level, tended to be associated with low or high levels of depression, respectively. However, an increase in substance use was not accompanied by an increase in depressive states. Moreover, depression varied greatly between adolescents, and according to gender and age. CONCLUSIONS: Depressive states and substance use in adolescents can vary considerably overtime, and are closely but rather synchronically related. Since most of the adolescents do not seek help for substance-related problems, substance use should be systematically assessed in adolescents presenting with a depressive state.

Conceptions et représentations comparées du "héros" : une catégorie complexe : étude comparative des données épiques grecques et vétérotestamentaires

Ce travail traite de la catégorie du « héros » et s'articule autour d'une comparaison entre les récits de la Grèce antique, principalement la poésie épique, et le Proche-Orient ancien, essentiellement les textes vétérotestamentaires - une étude dont l'objet est dès lors principalement textuel. Partant du constat, si simple mais lourd de conséquence, que le mot français « héros » vient du substantif grec rjpcoç, le texte débute par un travail de décentrement face aux référents contemporains liés à l'emploi du terme dans nos langues modernes : le « héros » n'est pas forcément le rjpcoç. Riche de cette analyse, la deuxième partie du travail se tourne vers l'Antiquité grecque, et plus précisément vers les poésies homérique et hésiodique. L'analyse de l'emploi du vocabulaire héroïque au sein de ces récits permet de cerner plus précisément les diverses figures appelées rjpcoç - figures qui semblent si différentes les unes des autres alors qu'elles partagent un qualificatif commun. Fort de cet apport quant à la compréhension du rjpcoç épique grec, une troisième partie questionne la présence de la catégorie du « héros » dans la Bible hébraïque mais aussi dans ses traductions en langues modernes. Constatant que le mot « héros » n 'apparaît jamais dans les langues anciennes que sont le grec de la LXX ou le latin de la Vulgate, les figures vétérotestamentaires sont repensées dans leur contexte proche- oriental, les voyant sous la lumière du Levant - lumière qui est la leur - et ce grâce au vocabulaire somme toute fort précis de la langue hébraïque. Finalement, une partie conclusive tente de mettre en exergue ce que la comparaison des récits grecs épiques et vétérotestamentaires a permis de soulever quant à leurs catégories « héroïques » respectives. L'enjeu est également de penser de manière critique ce que les cultures occidentales contemporaines nomment « héros », s'appuyant si souvent sur un « double héritage » gréco-romain et judéo-chrétien.

A t(7;12) balanced translocation with breakpoints overlapping those of the Williams-Beuren and 12q14 microdeletion syndromes.

The molecular characterization of balanced chromosomal rearrangements have always been of advantage in identifying disease-causing genes. Here, we describe the breakpoint mapping of a de novo balanced translocation t(7;12)(q11.22;q14.2) in a patient presenting with a failure to thrive associated with moderate mental retardation, facial anomalies, and chronic constipation. The localization of the breakpoints and the co-occurrence of Williams-Beuren syndrome and 12q14 microdeletion syndrome phenotypes suggested that the expression of some of the dosage-sensitive genes of these two segmental aneuploidies were modified in cells of the proposita. However, we were unable to identify chromosomes 7 and/or 12-mapping genes that showed disturbed expression in the lymphoblastoids of the proposita. This case showed that position-effect might operate in some tissues, but not in others. It also illustrates the overlap of phenotypes presented by patients with the recently described 12q14 structural rearrangements.

Taux sanguins et sériques d'ions métalliques chez les patients porteurs de PHTs à col modulaire - une étude de cohorte prospective comparative

Les évidences s'accumulent concernant des problèmes de corrosion touchant les prothèses à col modulaires. Plusieurs études récentes révèlent des taux d'ions métalliques élevés. Le but de cette étude était de comparer les taux d'ions métalliques (Co, Cr, Mo, Ti), dans le sérum, chez des porteurs de prothèses à col modulaire, à tige monobloc, ainsi que sans implant. Méthodes Nous avons recruté 60 patients, dont 50 porteurs d'une PTH, unilatérale, sans aucun autre implant, non-cimentée, avec tête en céramique, à minimum 1 année postopératoire. Quarante avaient une tige SPS (Symbios) (Ti6Al4 V) modulaire (col en CoCr) et 10 une SPS monobloc (non-modulaire). Les cupules étaient toutes en alliage de Ti (Ti6Al4 V) avec insert céramique ou PE. Nous avons constitué un groupe témoin sans aucun implant. Dans le groupe o modulaires O, le col a été choisi en préopératoire sur la base d'une planification 3D et assemblé à sec avant implantation. Nous avons prélevé un échantillon sérique, un autre sanguin, qui ont été analysés par spectrométrie de masse, permettant une détermination atomique quantitative. Le résultat clinique a été estimé à l'aide du o Oxford Hip Score O. Résultats Nous avons trouvé un Co sérique moyen à 1,54 Ig L dans le groupe O modulaires O et à 0,32 Ig L dans le groupe o monobloc O avec un p < 0,001. Pour le Cr, on a 1,12 Ig L (modulaires) vs 0,60 Ig L (monoblocs) avec un p < 0,001, pour le Ti 31 Ig L (modulaires) vs 22 Ig L (monoblocs) avec p < 0,001 et pour le Mo, 0,96 Ig L (modulaires) vs 0,74 (monoblocs) avec p = 0,254. Deux patients avaient des valeurs de Co supérieures à 7 Ig L et 11 étaient au-dessus de 1 Ig L, valeur considérée comme limite. Les valeurs dans le sang complet étaient similaires. Nous n'avons pas trouvé de différence significative selon les types de col modulaires (longs vs courts et rétro vs normaux). Curieusement, le taux de Cr était significativement plus élevé chez les patients sans aucun implant que chez les porteurs de SPS monobloc, par contre les différences n'étaient pas significatives pour les autres éléments. Conclusion Les taux sériques et sanguins de ions Co, Cr et Ti étaient significativement plus élevés dans le groupe des patients avec col modulaire, avec 2 valeurs 40 extrêmement hautes et plus de la moitié (11 40) anormalement hautes. Bien que ces valeurs soient inférieures à celles d'autres études, nous avons arrêter d'utiliser de tiges à cols modulaires, et avons initié un suivi annuel des patients porteurs, similaire à celui instauré pour les grosses têtes métal-métal.

Traitement pharmacologique de la schizophrénie: évaluation comparative de la qualité des recommandations de pratique clinique [Comparative evaluation of clinical practice guidelines for the treatment of schizophrenia]

INTRODUCTION: Many clinical practice guidelines (CPG) have been published in reply to the development of the concept of "evidence-based medicine" (EBM) and as a solution to the difficulty of synthesizing and selecting relevant medical literature. Taking into account the expansion of new CPG, the question of choice arises: which CPG to consider in a given clinical situation? It is of primary importance to evaluate the quality of the CPG, but until recently, there has been no standardized tool of evaluation or comparison of the quality of the CPG. An instrument of evaluation of the quality of the CPG, called "AGREE" for appraisal of guidelines for research and evaluation was validated in 2002. AIM OF THE STUDY: The six principal CPG concerning the treatment of schizophrenia are compared with the help of the "AGREE" instrument: (1) "the Agence nationale pour le développement de l'évaluation médicale (ANDEM) recommendations"; (2) "The American Psychiatric Association (APA) practice guideline for the treatment of patients with schizophrenia"; (3) "The quick reference guide of APA practice guideline for the treatment of patients with schizophrenia"; (4) "The schizophrenia patient outcomes research team (PORT) treatment recommendations"; (5) "The Texas medication algorithm project (T-MAP)" and (6) "The expert consensus guideline for the treatment of schizophrenia". RESULTS: The results of our study were then compared with those of a similar investigation published in 2005, structured on 24 CPG tackling the treatment of schizophrenia. The "AGREE" tool was also used by two investigators in their study. In general, the scores of the two studies differed little and the two global evaluations of the CPG converged; however, each of the six CPG is perfectible. DISCUSSION: The rigour of elaboration of the six CPG was in general average. The consideration of the opinion of potential users was incomplete, and an effort made in the presentation of the recommendations would facilitate their clinical use. Moreover, there was little consideration by the authors regarding the applicability of the recommendations. CONCLUSION: Globally, two CPG are considered as strongly recommended: "the quick reference guide of the APA practice guideline for the treatment of patients with schizophrenia" and "the T-MAP".
