Published: September 2013

Abstract
In 68% of cases, the left coronary ostium is at the free edge of the left sigmoid valve in 22% of cases over the edge of the valve and in 8% of cases under the free edge of the valve. In 56% of cases, the right coronary ostium is at the free edge of the left sigmoid valve in 28% of cases over the edge of the valve and in 16% of cases under the free edge of the valve. We found 5 cases with two right coronary ostium and 2 cases with two left coronary ostium. We found that in 38% of cases, the left coronary artery ends in three branches, such as anterior interventricular, circumflex and left marginal arteries, in rest of the cases, the left coronary artery ending by two branches like the anterior interventricular and circumflex arteries in which case the marginal artery originate from circumflex artery and rarely from anterior interventricular artery, or both, in this last case the left marginal artery being double. We found only 8 cases in which the circumflex artery ends as posterior interventricular artery in rest of the cases being represented by the right coronary artery end. Circumflex artery ends by two branches quite often and rarely with three branches which can sometimes be long, down to near the apex of the heart. In 8% of cases, the circumflex artery was less developed and do not vascularize other than the left side of the posterior surface of the left ventricle, sometimes his terminal ramus being left marginal artery. The right coronary artery frequently ends on diaphragmatic surface of the heart either as a single branch in posterior interventricular groove, by bifurcation or even rarely by trifurcation, when one or two branches are located in the posterior interventricular groove. Sometimes the right coronary artery ends on the posterior surface of the left ventricle, where the posterior interventricular artery occurs as collateral branch of the right coronary artery, the right coronary artery extending their vascularization territory to the posterior surface of the left ventricle, right up to the apex of the heart, the right coronary dominance, the circumflex artery in this case ending on the lateral surface of the heart. The right coronary artery may end up on the posterior surface of the right ventricle in which case posterior interventricular artery is represented by the terminal portion of the circumflex artery. The right coronary artery rarely ended as the posterior interventricular artery can reach the apex of the heart. We have found that the dominant type of a coronary artery can be held not only in the number of collateral, but also by their caliber at their origin from the aorta. We encountered 7 cases in which there is a third coronary artery, in 5 cases the third coronary artery being an anterior right I called her middle coronary artery or right ventricular branch and anterior ventricular artery, and in two cases the third coronary artery represent the circumflex artery. In 6 cases of the 7 cases described the third coronary artery showed no atrial branches

Abstract
Electric power consumption has been growing continuously, especially in the last years. Therefore, implementation of new advanced technologies such as the overhead line thermal monitoring is topical for improvement of the existing transmission line network in order to increase its throughput capacity and reliability of power supply. In general, the real-time thermal monitoring systems are designed based on the existing methods using the limiting conditions for ampacity determination of high-voltage overhead lines. The paper considers commonly used methods for thermal rating estimation which include computation of the conductor temperature and of the conductor sag. Comparative analysis was performed for the measured and calculated steady-state conductor temperatures and line sagging, based on which the thermal rating methods were tested. The experimental measurements were conducted for three cases using special monitoring equipment. The study has been carried out based on the existing line model of the Latvian transmission grid
Cauda equina syndrome secondary to lumbar disc herniation. Report of three cases
Authors: Adam Danil , Hornea Ioana 
Published: September 2013

Abstract
Cauda equina syndrome produced by the herniated lumbar intervertebral disc is a rare disorder that, if is undiagnosed and untreated in time, can have serious consequences for the patient and medicolegal implications for the surgeon. We report the clinical evolution of 3 patients with lumbar spinal stenosis who still present sphincterian and sexual dysfunctions many years after surgery, even if they were operated on immediately after admission. Reviewing the literature on this subject has allowed us to emphasize symptomes, pathophysiological mechanism and management regarding patients with lumbar spinal stenosis. The surgical decompression is indicated as soon as possible. The surgical decompression within 48 hours from onset allows maximum improvement of symptoms and absolves the surgeon of any medico-legal liability

Authors: Tascu A. , Florea Simona Mihaela 
Published: September 2013

Abstract
Background: There are yet to clarify some aspects regarding the surgical indications and surgical methods that are at choice for treating ACs. The purpose of the study is to contribute to the ongoing debate on the most appropriate treatment.
Materials and methods: We included in the study 44 pediatric patients (aged < 18 years), operated for ACs in the Neurosurgery I Department, of the Emergency Clinical Hospital “Bagdasar- Arseni” in Bucharest, during the period January 2003 to December 2012. The surgical methods were either a craniotomy or cyst shunting. The information regarding these patients was retrospectively assessed based on their clinical and imaging records, and cross checked with the OR protocols. Treatment efficiency was evaluated considering postoperative clinical status, imaging appearance and postoperative complications.
Results: 84.1% of the patients reported postoperative disappearance or reduction of symptoms, while 13.6 had the same complaints as prior surgery. Only one patient experienced worsening of symptoms. Follow-up imaging showed cyst disappearance in 29.5% patients and cyst reduction in 61.4% patients. 9.1% had no change in cyst volume. Craniotomy correlated with a better imaging appearance (p=0.02). There was no correlation between improved clinical status and cyst fluid reduction (p=0.6). 9 patients (20.4%), all with temporal cysts, experienced postoperative complications, and 7 of them (15, 9%) needed surgery. There was no severe or permanent dysfunction in any of the patients. 42.8% of the cyst shunting patients suffered postoperative complications, whereas only 10% of the craniotomy patients did.
Conclusion: Cyst decompression results in significant clinical improvement and it can be performed with little risk for severe complications. Craniotomy seems to be a better surgical treatment option than cystoperitoneal shunt, with a better neuroimaging appearance and a lower complications rate

Published: September 2013

AbstractAnisomycin is a pyrrolidine antibiotic isolated from Streptomyces griseolus. It has been found that a quite low dose of anisomycin is sufficient to block proliferation of primary T lymphocytes. The focus of this study is to explore the possibility of anisomycin to treat human acute leukemia Jurkat T cells in vitro. The results indicated that the low dose of anisomycin could significantly inhibit the colony formation of Jurkat T cells and elevate the inhibition rate of Jurkat T cell growth along with its increasing concentrations. Jurkat T cell cycle was blocked into S-phase by anisomycin. Consistent with the increased proportion of sub-G1 phase, anisomycin promoted Jurkat T cell apoptosis. The CD69 and CD25 expression on the surface of Jurkat T cells was also down-regulated prominently along with the enhancing concentrations of anisomycin, followed by the decreased production of IL-4, IL-10, IL-17, TGF-β and IFN-γ, and the down-regulated expression of phosphorylated-ERK1/2. The results suggest that the suppressive effect of anisomycin on Jurkat T cell growth may be related to inhibiting TGF-β production and ERK1/2 activation, arresting the cell cycle at S-phase and promoting the apoptosis of Jurkat T cells.
Vegetation diversity influences endozoochoric seed dispersal by moose (Alces alces L.)

Published: September 2013

AbstractResearch on moose-mediated seed dispersal is limited. However, its potential role in transferring seeds in patchy landscapes may be of great importance. In this work we examined how seasons and vegetation diversity influence the species richness and abundance of seeds dispersed endozoochorically by moose. Samples of moose faeces were collected year-round, fortnightly, from contrasting vegetation types, dominated by diverse, species-rich wetland or poor, dry pine forest. The viable seed content of dung was studied by the seedling emergence method. The mean number of emerged seedlings per 0.8 L sample and the mean number of plant species per 0.8 L sample were several times higher in the diverse wetland vegetation than in the poor pine forest vegetation. Maximum species richness and seed abundance was observed during the fructification period, and the minimum during spring. The species richness of samples did not differ between winter and the growing season, although the composition of plant species was different. The results of this study suggest that moose are efficient seed vectors, especially of grasses typical for grasslands and wetlands. The species richness and abundance of dispersed seeds coincides with the diversity of the vegetation of the animal’s habitat.

AbstractThe intercalation of natural montmorillonite with SiO2, SiO2-Al2O3 or SiO2-TiO2 pillars by the surfactant-directed method resulted in the formation of high surface area porous materials; these were tested as catalytic supports for the process of selective catalytic reduction of NO (DeNOx). The incorporation of titanium or aluminium into the structure of the silica pillars significantly increased the surface acidity of the clay samples. Iron and copper were deposited onto the surface of the pillared clays mainly in the form of monomeric isolated cations and oligomeric metal oxide species. The contribution of the latter species was higher in the clay intercalated with SiO2-TiO2 pillars than in the samples modified with SiO2 and SiO2-Al2O3 pillars. The pillared clay-based catalysts were active in the DeNOx process but, in this group, the best results were obtained for the clay intercalated with SiO2-TiO2 pillars and doped with iron and copper. The catalytic performance of the samples is discussed in respect of their surface acidity and active forms of transition metal species deposited.

AbstractFour water soluble azo dyes, 4-(isopropyl)-2-[(E)-(4-chlorophenyl)diazenyl]phenol (L 1), 4-(isopropyl)-2-[(E)-(2,4-dichlorophenyl)diazenyl]phenol (L2), 4-(sec-butyl)-2-[(E)-(4-chlorophenyl) diazenyl]phenol (L 3), 4-(sec-butyl)-2-[(E)-(2,4-dichlorophenyl)diazenyl]phenol (L 4), and their Cu(II) and Ni(II) complexes were synthesized and characterized using spectroscopic methods. Examination of their thermal stability revealed similar decomposition temperature of approximately 260–300°C and that they were more thermally stable than their metal complexes. Ni(II) complexes of ligands L2 and L4 were more stable than the other coordination compounds. Among the synthesized ligands, L2 and the complexes Cu(L3)2 and Ni(L4)2 showed both antimicrobial and antifungal activity. However, the other ligands and the complexes were poorly active against selected microorganisms.

Published: September 2013

Background: The clinical laboratory is the major producer of information used to diagnose, treat, and monitor patients. Errors in laboratory testing may occur at many different points in the total testing process (TTP). Application of quality control plays a vital role in recognizing probable errors. The current dominant technique for error identification uses quality control materials has several inherent drawbacks; otherwise, patient based quality control procedure ensures the detection of pre-analytical errors, analytical, post-analytical errors, clerical errors, and random errors that cannot be detected using commonly used quality control methods, thereby improving the reliability of clinical tests. Objective: Thus the objective of this study was to evaluate the practice of patient based quality control procedure in clinical chemistry unit at diagnostic laboratories in Nepal. Materials and Methods: The questionnaire based study was conducted in clinical chemistry unit of diagnostic laboratories across the country. Questionnaires were personally dropped in 217 clinical biochemistry laboratories and were asked to complete a practice based questionnaire. The responses of 169 laboratories were analyzed using Microsoft Excel 2007 and expressed in terms of percentage. Results: In foremost study undertaken, a total of 169 laboratories responded to the questionnaire. A total 65.9 % of the laboratories monitored errors using patient based quality control procedure but not as a part of quality control. Very few of participant.s laboratories responded accurately regarding utility and practical aspects of patient based quality control included in the checklist. Conclusion: Practice of patient based quality control procedure was not well established to identify possible errors. Hence, the study extent the existing information and explored that the current classical approaches were not adequate to assure accurate patients test results for specific analytes.

Du BIT à la politique sociale européenne : les origines d'un modèle
Authors: Mechi Lorenzo 
Published: September 2013

Entre les deux guerres, le BIT poursuivit l’objectif d’intégration économique du Vieux Continent, dans le but de favoriser la croissance, grâce à un processus de rationalisation, et ainsi de produire les ressources nécessaires pour la diffusion de réformes sociales. Quand, après la Seconde Guerre mondiale, l’intégration économique fut effectivement amorcée, le BIT contribua à faire prévaloir cette conception, qui imprégna fortement les traités des communautés européennes. Ces derniers reflètent donc une forte confiance dans l’effet positif des dynamiques du marché et comportent une dimension sociale très réduite, limitée à des mesures visant à stimuler la mobilité de la main-d’œuvre et à rendre plus performant le marché du travail européen. En synergie avec les politiques interventionnistes nationales, cette approche joua effectivement le rôle envisagé dans l’entre-deux-guerres : elle contribua à alimenter la croissance des Trente Glorieuses et à permettre la construction des États-providence européens. À partir des années 1980, dans un contexte caractérisé par des politiques macroéconomiques de plus en plus centrées sur la rigueur financière et la discipline budgétaire, elle a commencé pourtant à montrer toutes ses limites et son incapacité à garantir des niveaux satisfaisants d’emploi.
Réforme du droit et contestation sociale sans État de droit : le laboratoire chinois
Authors: Choukroune Leïla , Froissart Chloé 
Published: September 2013

Au cours des trente dernières années de réforme et d’ouverture, la Chine a progressivement mis en place un système juridique moderne au cœur duquel figure la garantie d’un certain nombre de droits fondamentaux. Cette importante transformation du régime influence aujourd’hui profondément les rapports sociaux. Qu’il s’agisse des salaires, des plans de restructuration, des délocalisations ou des heures supplémentaires impayées, les demandes formulées par les ouvriers chinois reposent sur un « langage des droits » lui-même fondé sur une base législative et réglementaire connue des travailleurs. Au centre de cette dynamique nouvelle et complexe entre reconnaissance des droits et absence d’État de droit, deux phénomènes méritent de retenir tout particulièrement l’attention : l’émergence, d’une part, d’une « public interest litigation » à la chinoise et, d’autre part, la mise en place progressive d’une forme originale de négociations collectives. Cet article se propose d’aborder ces deux formes de mobilisation en les mettant en perspective dans le contexte d’un État autoritaire, certes confronté à la nécessité de réformes, mais pas encore disposé à remettre en cause les fondements de son existence. Les avancées et limites du droit chinois apparaissent ainsi à la mesure des contradictions et hésitations du régime de Pékin.
Complices de Hitler ou victimes de Staline ? Les déplacés baltes en Allemagne de la sortie de guerre à la guerre froide
Authors: Denis Juliette 
Published: September 2013

Cet article retrace la structuration et le sort des réfugiés baltes présents en Allemagne à la fin de la Seconde Guerre mondiale en confrontant les archives soviétiques, occidentales et la voix des réfugiés. La réputation collective du groupe, déterminante pour ses perspectives migratoires, évolue au gré du rapport de force entre l’URSS et ses anciens alliés. La transition de la Seconde Guerre mondiale à la guerre froide définit alternativement les Displaced Persons ( DPs ) baltes comme « complices de Hitler » et « victimes de Staline ». Les institutions internationales, les commandements des zones d’occupation occidentales en Allemagne et les autorités soviétiques alimentent les controverses qui se soldent par l’émigration massive des DPs vers l’Ouest. Dans ce processus, les DPs baltes apparaissent non seulement comme l’objet de politiques antagonistes, mais également comme l’instrument d’un conflit idéologique. Par la voix de leurs représentants ou par des démarches collectives, ils parviennent à se positionner dans les conflits de la guerre froide naissante et à forger une identité qui favorise leur émigration à l’Ouest.
La symbiose partielle
Authors: de Luca-Bernier Catherine 
Published: September 2013

Le travail auprès de patients psychotiques expose les soignants à des manifestations touchant au corps vécu. Or, au-delà d’une conception péjorative en termes d’« infiltration » ou de « contamination », il est possible, à partir d’éprouvés corporels, d’envisager un processus thérapeutique, dans un lien transférentiel, mettant en jeu certaines parties du corps du thérapeute, et venant combler les failles dans l’image du corps du patient. Ce processus peut être qualifié de « symbiose partielle ».

Published: September 2013

Cet article vise à montrer comment chercheurs et cliniciens peuvent collaborer et s’enrichir mutuellement en utilisant la « consultation systémique », en deux séances, dont le but est l’évaluation des interactions familiales, avec mise en lumière des ressources comme des difficultés de la famille. Lors d’une première rencontre, les questions qui motivent les parents et/ou le(s) thérapeute(s) à consulter sont formulées et la famille est invitée à faire des jeux familiaux semi-standardisés qui sont filmés. Lors d’une deuxième rencontre réunissant les mêmes personnes, un visionnement d’extraits des films sert de base aux réponses des chercheurs et à une discussion commune. Une vignette clinique, concernant des violences intrafamiliales, illustrera la richesse et l’utilité de ces consultations et montrera qu’une collaboration entre chercheurs et cliniciens est fructueuse pour toutes les parties concernées.
