R-ArcticNet, A Regional Hydrographic Data Network for the Pan-Arctic Region (ISO-image of CD-ROM)

We describe the contemporary hydrography of the pan-Arctic land area draining into the Arctic Ocean, northern Bering Sea, and Hudson Bay on the basis of observational records of river discharge and computed runoff. The Regional Arctic Hydrographic Network data set, R-ArcticNET, is presented, which is based on 3754 recording stations drawn from Russian, Canadian, European, and U.S. archives. R-ArcticNET represents the single largest data compendium of observed discharge in the Arctic. Approximately 73% of the nonglaciated area of the pan-Arctic is monitored by at least one river discharge gage giving a mean gage density of 168 gages per 106 km2. Average annual runoff is 212 mm yr?1 with approximately 60% of the river discharge occurring from April to July. Gridded runoff surfaces are generated for the gaged portion of the pan-Arctic region to investigate global change signals. Siberia and Alaska showed increases in winter runoff during the 1980s relative to the 1960s and 1970s during annual and seasonal periods. These changes are consistent with observations of change in the climatology of the region. Western Canada experienced decreased spring and summer runoff.

CD-ROM Acrobat Journals Using Networks

The available technologies for publishing journals electronically are surveyed. They range from abstract representations, such as SGML, concerned largely with the structure of the document, to formats such as PostScript which faithfully model the layout and the appearance. The issues are discussed in the context of choosing a format for electronically publishing the journal: Electronic Publishing -- Origination, Dissemination and Design. PostScript is neither widely enough available nor standardised enough to be suitable; a bitmapped pages approach suffers from being resolution-dependent in terms of the visual quality achievable. Reasons are put forward for the final choice of Adobe s new PDF document standard for creating electronic versions of the journal.

Gestaltwandlungen des Imperiums. Heiner Muller und Rom

Die Arbeit schlägt eine systematische Studie der Rezeption des antiken Rom in den Werken von Heiner Müller vor. Die Analyse von Dramen, Gedichten und Essays, sowie von Interviews und Manuskripten, liefert ein umfassendes Bild wiederholter und vielschichtiger Begegnungen mit der römischen Geschichte und Literatur, die bisher weitgehend im kritischen Diskurs im Schatten standen. Der Schwerpunkt der Analyse liegt einerseits auf dem philologisch-literarischen Vergleich mit diesen Quellen und andererseits auf der darauf basierenden Rekonstruktion des umfassenden Bildes eines Imperiums, das seine historischen Grenzen überschreitet, um zu einem zivilisatorischen Prinzip zu werden, so allgegenwärtig wie ambivalent – das "Urbild" einer unauflöslichen Verschränkung von Staat und Gewalt, Kultur und Barbarei, Gesetz und Terror. Diese kulturelle Prägung zeigt sich nicht nur in Werken mit römischem Thema, sondern auch in nachfolgenden historischen Konstellationen, die Müller inszenierte, vom Elisabethanischen England über das Preußen Friedrichs II. bis hin zu den Blöcken des 20. Jahrhunderts. Besondere Aufmerksamkeit wird der Untersuchung literarischer Einflüsse und philosophischer Vorgänger dieser zivilisationskritischen Vision Roms gewidmet – eine Untersuchung, die bestehende Interpretationen korrigiert und neue einführt. Im Lichte des thematischen Komplexes "Rom" wird so ein beträchtlicher Teil von Müllers Produktion neu interpretiert, wodurch ein neues hermeneutisches Paradigma ebenso wie bisher übersehene Einflüsse und intertextuelle Beziehungen bei der Untersuchung von Dramen und Lyrik hervortreten.

Determination of the maximum inhibitory dilution of cetylpyridinium chloride-based mouthwashes against staphylococcus aureus: an in vitro study

The aim of this in vitro study was to determine the maximum inhibitory dilution (MID) of four cetylpyridinium chloride (CPC)-based mouthwashes: CPC+Propolis, CPC+Malva, CPC+Eucaliptol+Juá+Romã+Propolis (Natural Honey®) and CPC (Cepacol®), against 28 Staphylococcus aureus field strains, using the agar dilution method. Decimal dilutions ranging from 1/10 to 1/655,360 were prepared and added to Mueller Hinton Agar. Strains were inoculated using Steers multipoint inoculator. The inocula were seeded onto the surface of the culture medium in Petri dishes containing different dilutions of the mouthwashes. The dishes were incubated at 37ºC for 24 h. For readings, the MID was considered as the maximum dilution of mouthwash still capable of inhibiting microbial growth. The obtained data showed that CPC+Propolis had antimicrobial activity against 27 strains at 1/320 dilution and against all 28 strains at 1/160 dilution, CPC+Malva inhibited the growth of all 28 strains at 1/320 dilution, CPC+Eucaliptol+Juá+Romã+Propolis inhibited the growth of 2 strains at 1/640 dilution and all 28 strains at 1/320 dilution, and Cepacol® showed antimicrobial activity against 3 strains at 1/320 dilution and against all 28 strains at 1/160 dilution. Data were submitted to Kruskal-Wallis test, showing that the MID of Cepacol® was lower than that determined for the other products (p<0.05). In conclusion, CPC-mouthwashes showed antimicrobial activity against S. aureus and the addition of other substances to CPC improved its antimicrobial effect.

Acidentes de transporte em Cuiabá, Mato Grosso: morbi-mortalidade

Os acidentes de trânsito continuam a se constituir em um importante problema de saúde pública no Brasil. Objetivo : Analisar as características dos acidentes de transporte terrestre e suas vítimas no município de Cuiabá. Método: Para o estudo da mortalidade foram obtidos dados do Sistema de Informações sobre Mortalidade /Ministério da Saúde, disponíveis em CD-ROM referente aos anos de 1980-2005; para o de morbidade hospitalar foram utilizados os dados Sistemas de Informações Hospitalares no período de 1998-2006 e para o estudo da demanda das unidades de urgência e emergência foi utilizado um banco de dados construído especialmente para esse fim, referente aos meses de maio a junho de 2005. Adotaram-se os conceitos definições estabelecidos na Classificação Internacional de Doenças 10: acidentes de transporte (categ. V01-V99) e acidente de transporte terrestre (V01-V89). Resultados: Em todas as análises, as taxas de mortalidade/morbidade hospitalar se expressaram com valores maiores que a média brasileira. Apesar de apresentar aspectos distintos entre mortalidade, morbidade hospitalar e morbidade da demanda de unidades de urgência e emergência, destacam-se como principais vítimas os jovens do sexo masculino; a vítima qualificada como "ocupante" predomina nos acidentes fatais e os "motociclistas", nos não fatais.Conclusão: este estudo revela que Cuiabá é uma área onde os acidentes de transporte terrestre devem ser tratados como prioridade devido à sua magnitude, seja na mortalidade ou morbidade, trazendo subsídios para o seu enfrentamento

Gait kinematic analysis in patients with a mild form of central cord syndrome

Background: Central cord syndrome (CCS) is considered the most common incomplete spinal cord injury (SCI). Independent ambulation was achieved in 87-97% in young patients with CCS but no gait analysis studies have been reported before in such pathology. The aim of this study was to analyze the gait characteristics of subjects with CCS and to compare the findings with a healthy age, sex and anthropomorphically matched control group (CG), walking both at a self-selected speed and at the same speed. Methods: Twelve CCS patients and a CG of twenty subjects were analyzed. Kinematic data were obtained using a three-dimensional motion analysis system with two scanner units. The CG were asked to walk at two different speeds, at a self-selected speed and at a slower one, similar to the mean gait speed previously registered in the CCS patient group. Temporal, spatial variables and kinematic variables (maximum and minimum lower limb joint angles throughout the gait cycle in each plane, along with the gait cycle instants of occurrence and the joint range of motion ROM) were compared between the two groups walking at similar speeds. Results: The kinematic parameters were compared when both groups walked at a similar speed, given that there was a significant difference in the self-selected speeds (p < 0.05). Hip abduction and knee flexion at initial contact, as well as minimal knee flexion at stance, were larger in the CCS group (p < 0.05). However, the range of knee and ankle motion in the sagittal plane was greater in the CG group (p < 0.05). The maximal ankle plantar-flexion values in stance phase and at toe off were larger in the CG (p < 0.05). Conclusions: The gait pattern of CCS patients showed a decrease of knee and ankle sagittal ROM during level walking and an increase in hip abduction to increase base of support. The findings of this study help to improve the understanding how CCS affects gait changes in the lower limbs.

ASSOCIATION BETWEEN SADDLE NOSE DEFORMITY AND RETRO-ORBITAL MASS IN WEGENER`S GRANULOMATOSIS

Objectives: The relationship between saddle nose deformity (SND) in Wegener`s granulomatosis (WG) and other clinical features, including retro-orbital mass formation (ROM), has been poor described. Therefore, this relationship was analyzed retrospectively from 2000 to 2010. Patients and Methods: Eighteen consecutive WG patients with SND diagnosed by computed tomography were matched to 36 WG patients without SND (control group) for gender, age at WG diagnosis and disease duration. Results: No difference was found between the two groups in relation to WG type (limited and systemic forms), ethnicity, laboratory features, constitutional symptoms or clinical manifestations, including upper respiratory tract, and treatment, except for ROM (33.3 vs. 2.8% in SND(+) and SND(-) groups, respectively; p=0.004) and subglottic stenosis (22.2 vs. 2.8%; p=0.038). However, on multivariate analysis, only ROM (OR 17.15; 95% CI 1.11-265.52) was statistically associated to SND. In addition, in more than half of the cases, SND manifested prior to ROM. Conclusions: Results of this prospective analysis showed that SND was strongly associated to ROM in WG. Since early diagnosis and aggressive treatment of orbital involvement could lead to better prognosis, the presence of SND warrants additional vigilance.

Cervical Mobility in Women With Migraine

Objective.-To contrast the cervical range of motion (CROM) in women with episodic migraine (EM), transformed migraine (TM), and controls without migraine headaches. Background.-Migraineurs often complain about neck pain. Furthermore, neck problems can worsen the headaches in individuals with migraine. Individuals with neck pain usually have reduced CROM. Nonetheless, studies assessing the CROM in migraineurs are scarce. Methods.-Our sample was selected in an outpatient headache clinic, and consisted of 45 women aged 20-54 years old, 15 per group. Cervical mobility was evaluated in movements of flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation using the CROM technique, and was contrasted among the groups. Migraine clinical patterns were also evaluated ( frequency, duration of migraine, pain in the moment of evaluation, pain in movement, and pain localization) as a function of CROM. Results.-Compared with controls, individuals with TM had numerically inferior CROM in all parameters, and significant reduction in 3 of them: extension (59.3 vs 68.1, P = .02), left lateral flexion (44.5 vs 49.1, P = .03), and right rotation (62.2 vs 69.6, P = .02). Compared with individuals with migraine, the TM group presented significantly reduced mobility only for extension ( 59.3 vs 68.4, P = .02). Migraineurs also had numerically inferior ROM, contrasted to controls, in 5 of the 6 parameters, although significance was seen just for right rotation (60.8 vs 68.6 P < .01). There was no correlation between cervical mobility and migraine parameters. The CROM was not reduced for the symptomatic side of migraine, in cases of unilateral pain. Conclusion.-Contrasted to controls, individuals with episodic and TM have decreased cervical range of motion.

Physical therapy assessment tools to evaluate disease progression and phenotype variability in Golden Retriever muscular dystrophy

Dogs suffering from Golden Retriever muscular dystrophy (GRMD) present symptoms that are similar to human patients with Duchenne muscular dystrophy (DMD). Phenotypic variability is common in both cases and correlates with disease progression and response to therapy. Physical therapy assessment tools were used to study disease progression and assess phenotypic variability in dogs with GRMD. At 5 (TO), 9 (T1), 13 (T2) and 17 (T3) months of age, the physical features, joint ranges of motion (ROM), limb and thorax circumferences, weight and creatine kinase (CK) levels were assessed in 11 dogs with GRMD. Alterations of physical features were higher at 13 months, and different disease progression rates were observed. Passive ROM decreased until 1 year old, which was followed by a decline of elbow and tarsal ROM. Limb and thorax circumferences, which were corrected for body weight, decreased significantly between TO and T3. These measurements can be used to evaluate disease progression in dogs with GRMD and to help discover new therapies for DMD patients. (C) 2011 Elsevier Ltd. All rights reserved.
