Abstract
BACKGROUND: Meningiomas are the most common primary central nervous system neoplasms originating from the arachnoid cap cells and constitute between 13% and 26% of all intracranial tumors.
AIMS AND OBJECTIVES: The aim of the study was to analyze the age-, sex-, and site-wise distribution of different histological patterns of meningiomas seen in our center and to assess the status of estrogen receptor (ER), progesterone receptor (PR), and proliferation marker Ki-67 in various grades of meningioma.
MATERIALS AND METHODS: A prospective study was done in 90 cases. Patients presented with symptoms of headache and seizure and underwent subsequent excision surgery at Neurosurgery Department were taken. We have studied histological typing and grading of the tumors, and immunohistochemical staining was done for ER, PR, and Ki-67.
STATISTICAL ANALYSIS: Two-group comparison was done using Mann–Whitney U-test and Fisher’s exact test. Comparison of Ki-67 expression between Grade 1 and Grade 2 meningiomas was determined using Mann–Whitney U-test. Comparison of ER and PR status between different histological grades was done by Fisher’s exact test. Two-tailed P < 0.001 was considered statistically significant.
RESULTS: According to histological type, meningothelial meningioma is most common (38.8%) followed by transitional (22.2%). PR positivity is seen in 96.34% of Grade 1 tumors, and all Grade 2 tumors were PR negative (Fisher’s exact test P < 0.001). About 3.66% of Grade 1 and all Grade 2 tumors were positive for ER (Fisher’s exact test two-tailed P < 0.001). Mean Ki-67 labeling index (LI) was 2.57 ± 1.674 among Grade I tumors, 7.11 ± 1.084 in Grade II meningiomas.
CONCLUSIONS: Most of Grade 1 meningiomas show PRs positivity and lack of ERs positivity. Meningiomas with higher proliferation index and negative PR are very likely to be Grade II or Grade III. Evaluation of ER, PR status, and Ki-67 labeling index (LI) with histological evaluation helps us in providing information about the biologic behavior of meningiomas.

Abstract
INTRODUCTION: Resistance to antimicrobial agents is a major concern worldwide and is exemplified by the global spread of the Methicillin resistant Staphylococcus aureus (MRSA). Health care workers (HCWs) and asymptomatically colonized patients are important sources of nosocomial MRSA infections.
AIMS AND OBJECTIVES: To determine the prevalence of MRSA colonisation, two hundred HCWs and 200 consecutive outpatients attending our tertiary care hospital were studied.
MATERIALS AND METHODS: Two sterile pre-moistened cotton tipped swabs were used to collect specimens from their anterior nares. These were inoculated immediately on Blood agar with oxacillin, Mannitol salt agar with oxacillin and CHROM agar. Resistance to cefoxitin was confirmed by PCR by demonstration of mecA gene. Antibiotic susceptibility was determined by Kirby Bauer’s disc diffusion method and MIC of vancomycin by using broth dilution and Vitek-2 Compact system.
RESULTS: The nasal carriage of MRSA among HCWs was found to be 7.5% and in outpatients 3%. All strains of MRSA from HCWs and outpatients grew on three selective media and mecA gene amplified in all of them. All the isolated strains of MRSA showed high degree of resistance to co-trimoxazole (93.3%), ciprofloxacin (80%) and erythromycin (66.66%). However, there was 100% susceptiability to vancomycin, teicoplanin, linezolid and Rifampicin.
CONCLUSION: Although a direct casual relationship could not be established, it could be assumed that the transmission from colonised health care worker is responsible atleast in part for MRSA infection among patients. Therefore emphasis should be laid on strict implementation of standard infection control practices which would help in minimizing the carriage and transmission of MRSA in the hospital.

<p>Artemisia, one of the larger genera in the family Asteraceae, comprises from 200 to more than 500 taxa at the specific or subspecific level. Artemisia herba-alba Asso (Shih) is grown in North Africa and certain parts of Asia and Middle East. It is one of the most widely used plants in the Algerian folk medicine. The antioxidant and free radical scavenging activities of the methanolic extracted materials were tested together with their antibacterial effects against isolated bacterial strains causing food poisoning. In summary, <em>A. herba-alba</em> Asso represent a good phenolic and flavonoid content (161, 64 mg/g and 16,83mg/g, respectively) in comparison with <em>T. capitatus</em> L which represent a phenolic content of 131, 48 mg/g and 14, 96 of flavonoid content. The results shows also that the methanolic extracts of the two plants possess a strong antioxidant (DPPH, FRAP assays) and antibacterial activities, which supports their ethnopharmacological use and <em>A. herba alba</em> represent the highest values (IC 50: 2, 35 mg/ml and OD 1, 13 at 700nm). Our results show the interest of <em>A. herba-alba</em> Asso and <em>T. capitatus</em> L, among other medicinal plants, in search of new chemo-preventive agents against biofilm and planktonic growth of food spoilage pathogens. Further studies are envisaged to target the most interesting molecules responsible for these activities. It is concluded that organic extracts from <em>Artemisia herba alba</em> Asso, exert strong antioxidant activities which are related to their polyphenol contents. </p>

Abstract. This study was undertaken to investigate the susceptibility of rhesus monkeys to the calpox virus, an orthopoxvirus (OPXV) of the Cowpox virus species (CPXV), which is uniformly lethal in common marmosets. Six rhesus monkeys were either intravenously (i.v.) or intranasally (i.n.) exposed to the virus. Monitoring of the macaques after viral exposure included physical examinations, the determination of viral load by real-time PCR and plaque assay, and the analysis of humoral responses. Two i.v. inoculated animals developed numerous classical pox lesions that started after inoculation at days 7 and 10. Both animals became viremic and seroconverted. They exhibited maximal numbers of lesions of approximately 50 and 140 by day 21. One animal completely recovered, while the other one suffered from a phlegmonous inflammation of a leg initially induced by a secondarily infected pox lesion and was euthanized for animal welfare reasons. In contrast to previous pathogenicity studies with the calpox virus in marmosets, none of the four animals inoculated intranasally with doses of the calpox virus exceeding those used in marmosets by orders of magnitude showed typical clinical symptoms. No viral DNA was detectable in the blood of those animals, but three animals seroconverted. In two of these three animals, infectious virus was sporadically isolated from saliva. This indicates that rhesus monkeys are less susceptible to calpox virus infection, which limits their use in further intervention studies with OPXV.
Global patterns in Earth's dynamic topography since the Jurassic: the role of subducted slabs

Published: September 2017

Abstract. We evaluate the spatial and temporal evolution of Earth's long-wavelength surface dynamic topography since the Jurassic using a series of high-resolution global mantle convection models. These models are Earth-like in terms of convective vigour, thermal structure, surface heat-flux and the geographic distribution of heterogeneity. The models generate a degree-2-dominated spectrum of dynamic topography with negative amplitudes above subducted slabs (i.e. circum-Pacific regions and southern Eurasia) and positive amplitudes elsewhere (i.e. Africa, north-western Eurasia and the central Pacific). Model predictions are compared with published observations and subsidence patterns from well data, both globally and for the Australian and southern African regions. We find that our models reproduce the long-wavelength component of these observations, although observed smaller-scale variations are not reproduced. We subsequently define geodynamic rules for how different surface tectonic settings are affected by mantle processes: (i) locations in the vicinity of a subduction zone show large negative dynamic topography amplitudes; (ii) regions far away from convergent margins feature long-term positive dynamic topography; and (iii) rapid variations in dynamic support occur along the margins of overriding plates (e.g. the western US) and at points located on a plate that rapidly approaches a subduction zone (e.g. India and the Arabia Peninsula). Our models provide a predictive quantitative framework linking mantle convection with plate tectonics and sedimentary basin evolution, thus improving our understanding of how subduction and mantle convection affect the spatio-temporal evolution of basin architecture.
An Unusual Case of Portal Hypertension Secondary to Primary Hypoplasia of the Portal Vein
Authors: Harris Lauren , Reems Miryam , Dial Sharon 
Published: September 2017

ABSTRACTPrimary hypoplasia of the portal vein with secondary portal hypertension and acquired portosystemic collateral circulation is infrequently reported in the veterinary literature. Diagnosis of this condition requires documentation of abnormal hepatocellular function, the lack of intrahepatic or extrahepatic macroscopic congenital portosystemic shunts, and liver histopathology demonstrating portal hypoperfusion in the absence of hepatic inflammation or nodular regeneration. Due to a perceived poor prognosis, many patients with this condition are euthanized; however, those that are spared can be medically managed, in some cases for years. This case report describes the diagnosis and management of a patient with primary hypoplasia of the portal vein and secondary portal hypertension that presented with the severe but typical clinical manifestations of ascites and hepatic encephalopathy, normal liver enzyme concentrations, and normal serum bile acid concentrations.
Successful Surgical Correction of a Mesenteric Volvulus with Concurrent Foreign Body Obstruction in Two Puppies

ABSTRACT
A 9 mo old female intact English mastiff (case 1) presented for anorexia and vomiting for 7 days. A 7 mo old male castrated American bulldog (case 2) presented for vomiting and anorexia for 2 days without diarrhea. Both dogs were diagnosed with mesenteric volvulus based on exploratory laparotomy, which also revealed an intestinal foreign body obstruction. Case 1 required critical care support during recovery but was ultimately discharged, whereas case 2 had an uncomplicated recovery. Both were reported to be back to normal 1 wk after surgery. Case 1 survived 3 mo and then died due to a colonic torsion diagnosed by exploratory laparotomy. Case 2 has been reported to be completely normal more than 18 mo after surgery. These two cases illustrate that mesenteric volvulus can be present with a several-day history of gastrointestinal signs and that shock may be absent on presentation. This is also the first published report of mesenteric volvulus with a concurrent foreign body obstruction.

La cosmovision maya et le patriarcat : une interprétation critique1
Authors: Cumes Aura 
Published: September 2017

Dans cet article, l’auteure cherche à répondre aux questions suivantes : Le patriarcat a-t-il toujours été un système universel de domination? Les sociétés dites « non occidentales » sont-elles aussi des sociétés patriarcales? Que dit la pensée maya ancienne (la cosmovision maya) à propos des relations hommes-femmes? Quelles sont les relations de pouvoir qui mènent au patriarcat? Pour répondre, l’auteure centre d’abord son analyse sur un texte ancien nommé « Popol Wuj » en langue K’iche’, ce qui se traduit généralement par « Livre du conseil ». Ensuite, elle analyse sommairement la construction des structures relationnelles entre les femmes et les hommes mayas dans un contexte de colonisation. Analyser le Popol Wuj est un projet ambitieux qui demande beaucoup de temps. Pour cette raison, l’auteure ne cherche pas à parler de ce texte en lui-même, mais plutôt à faire un exercice d’interprétation sur ce qu’il dit à propos des relations entre les hommes et les femmes, entre le féminin et le masculin, afin de le mettre en rapport avec l’histoire subséquente qui débute par la colonisation.
Les miss et les reines de carnaval autochtones au Québec : défier les modèles et les normes
Authors: Bousquet Marie-Pierre , Morissette Anny , Hamel-Charest Laurence 
Published: September 2017

Les élections pour couronner des femmes symbolisant leur groupe social existent depuis les années 60 chez les peuples amérindiens du Québec. De nos jours, deux sortes de concours existent : ceux de miss et ceux de reines de carnaval, chacun valorisant différents types d’idéaux féminins. Les auteures émettent l’hypothèse que ces spectacles sociaux véhiculent des modèles complémentaires ou contradictoires qui montrent combien être une Amérindienne peut se révéler complexe. Entre la défense du territoire et la trousse à maquillage, les concours mettent en jeu des codes et des normes qui s’entrechoquent et théâtralisent d’apparentes antinomies.
Des récits de réfugiées palestiniennes à travers la grille de l’intersectionnalité
Authors: Caron Roxane , Damant Dominique , Flynn Catherine 
Published: September 2017

Cet article s’inscrit dans une lignée de travaux féministes qui cherchent à rendre leur juste place aux « voix silencieuses », dont celles des Palestiniennes. S’appuyant sur une étude qualitative consacrée à l’exil de réfugiées palestiniennes, les trois auteures tracent le portrait des expériences de ces femmes, expériences qui se déclinent en quatre périodes : lanakba, lathawra, les guerres et l’après-guerre. Au fil des témoignages, les auteures constatent que les expériences en question sont structurées par le genre et le temps, mais que les femmes ne sont ni victimes totalement ni héroïnes en tout temps.
Les courbes de son monde : mobilités d’une commerçante angolaise dans la périphérie globale
Authors: Barreau-Tran Léa 
Published: September 2017

Cet article porte sur les expériences professionnelles de voyage des commerçantes à la valise angolaises nommées « moambeiras ». En Angola, la féminisation de ce commerce s’est intensifiée avec la fin de la guerre en 2002 et l’ouverture des relations internationales avec des partenaires comme le Brésil et la Chine. Les voyages d’affaires de ces femmes chamboulent les rôles de genre et la répartition des pouvoirs dans la famille. Interrogeant les processus émancipatoires en jeu dans ces pratiques, l’auteure examine la façon dont la circulation commerciale permet aux femmes de prendre conscience des rapports de pouvoir qui les marginalisent et de développer leur capacité à les transformer. À l’heure de l’accélération de la globalisation des échanges entre pays du Sud, l’auteure a pour ambition de donner une vision intimiste et féministe de la mobilité en suivant le récit de la mobilité d’une femme en s’appuyant sur une carte du monde.
Estimation of Melt Pond Fractions on First Year Sea Ice Using Compact Polarization SAR
Authors: Li Haiyan , Perrie William , Li Qun , Hou Yijun 
Published: September 2017

AbstractMelt ponds are a common feature on Arctic sea ice. They are linked to the sea ice surface albedo and transmittance of energy to the ocean from the atmosphere and thus constitute an important process to parameterize in Arctic climate models and simulations. This paper presents a first attempt to retrieve the melt pond fraction from hybrid‐polarized compact polarization (CP) SAR imagery, which has wider swath and shorter revisit time than the quad‐polarization systems, e.g., from RADARSAT‐2 (RS‐2). The co‐polarization (co‐pol) ratio has been verified to provide estimates of melt pond fractions. However, it is a challenge to link CP parameters and the co‐pol ratio. The theoretical possibility is presented, for making this linkage with the CP parameter C22/C11 (the ratio between the elements of the coherence matrix of CP SAR) for melt pond detection and monitoring with the tilted‐Bragg scattering model for the ocean surface. The empirical transformed formulation, denoted as the “compact polarization and quad‐pol” (“CPQP”) model, is proposed, based on 2062 RS‐2 quad‐pol SAR images, collocated with in situ measurements. We compared the retrieved melt pond fraction with CP parameters simulated from quad‐pol SAR data with results retrieved from the co‐pol ratio from quad‐pol SAR observations acquired during the Arctic‐Ice (Arctic‐Ice Covered Ecosystem in a Rapidly Changing Environment) field project. The results are shown to be comparable for observed melt pond measurements in spatial and temporal distributions. Thus, the utility of CP mode SAR for melt pond fraction estimation on first year level ice is presented.

AbstractDetermining effective strategies for mitigating surface ozone (O3) pollution requires knowledge of the relative ambient concentrations of its precursors, NOx, and VOCs. The space‐based tropospheric column ratio of formaldehyde to NO2 (FNR) has been used as an indicator to identify NOx‐limited versus NOx‐saturated O3 formation regimes. Quantitative use of this indicator ratio is subject to three major uncertainties: (1) the split between NOx‐limited and NOx‐saturated conditions may shift in space and time, (2) the ratio of the vertically integrated column may not represent the near‐surface environment, and (3) satellite products contain errors. We use the GEOS‐Chem global chemical transport model to evaluate the quantitative utility of FNR observed from the Ozone Monitoring Instrument over three northern midlatitude source regions. We find that FNR in the model surface layer is a robust predictor of the simulated near‐surface O3 production regime. Extending this surface‐based predictor to a column‐based FNR requires accounting for differences in the HCHO and NO2 vertical profiles. We compare four combinations of two OMI HCHO and NO2 retrievals with modeled FNR. The spatial and temporal correlations between the modeled and satellite‐derived FNR vary with the choice of NO2 product, while the mean offset depends on the choice of HCHO product. Space‐based FNR indicates that the spring transition to NOx‐limited regimes has shifted at least a month earlier over major cities (e.g., New York, London, and Seoul) between 2005 and 2015. This increase in NOx sensitivity implies that NOx emission controls will improve O3 air quality more now than it would have a decade ago.
