Vascular Parkinsonism: Analysis Of Seven Cases

INTRODUCTION: Neuroimaging studies of elderly individuals reveal alterations in the white matter that are incompatible with the patient's parkinsonism, mistakenly classified as vascular parkinsonism (VP). METHOD: This study was conducted on a population composed of 20 patients with Parkinson's disease (PD) whose neuroimaging exams revealed vascular alterations in the white matter and seven patients with VP in order to compare diagnostic criteria. RESULTS: Age at disease onset of patients with PD was 55±12 years and patients with VP it was 62±13 years. Twelve patients with PD and five patients with VP presented arterial hypertension; three patients with VP and two patients with PD presented gait impairment; all patients with VP presented rigidity and bradykinesia, six of them presented resting tremor; 19 patients with PD presented tremor and 19 of them presented rigidity, while 17 presented bradykinesia. When the symptoms and evolution of both diseases were compared, the vascular alterations in the white matter were considered unspecific. CONCLUSION: Since clinical symptoms are unspecific, a differential diagnosis requires neuroimaging, good response to levodopa and clinical evolution. © 2006 Associação Arquivos de Neuro-Psiquiatria.6403:00:00Critchley, M., Arteriosclerotic parkinsonism (1929) Brain, 52, pp. 23-83Winikates, J., Jankovic, J., Clinical correlates of vascular parkinsonism (1999) Arch Neurol, 56, pp. 98-102Demirkiran, M., Bozdemir, H., Sarica, Y., Vascular parkinsonism: A distinct, heterogeneous clinical entity (2001) Acta Neurol Scand, 104, pp. 63-67Thanvi, B., Lo, N., Robinson, T., Vascular parkinsonism: An important cause of parkinsonism in older people (2005) Age Ageing, 34, pp. 114-119Zijlmans, J.C.M., Thijssen, H.O.M., Vogels, O.J.M., MRI in patients with suspected vascular parkinsonism (1995) Neurology, 45, pp. 2183-2188Bennet, D.A., Wilson, R.S., Gilley, D.W., Fox, J.H., Clinical diagnosis of Binswanger disease (1990) J Neurol Neurosurg Psychiatry, 53, pp. 961-965Hurtig, H.I., Vascular parkinsonism (1993) Parkinsonian Syndromes, pp. 81-83. , Stern MB, Koller WC (eds).

HUMUS FLORESTAIS: SINTESE E DIAGNOSTICO DAS INTERRELACÕES VEGETAÇÃO/SOLO

With an essentially ecosystem approach this paper tries to present the problem of the soil organic matter under its most interactive aspect: soil-vegetation interrelationships. The macro-morphological study of the humus type in some forest ecosystems of the intertropical Brazilian coast faced both with dilferent approaches and bibliography resulls about organic matter of forest soils. Thus, the different uses of the humus concept, which perrneates different research, will be clarified to show further ahead our resulls both about the quantitative characteristics of humus layers and their morphological structure in order to classify the humus forms of the Resting and Atlantic forest. The resulls contradict the hypothesis, generally accepted, that in tropical regions the faster recycling of soil organic matter leads to determine humic structures of the mull-like type. The dynamics of the interactive processes arnong litter fall, mineral substrata and decomposer communities (microorganisms and fauna) is analyzed in order to elucidate lhe factors which determine the diversity of the humus form in Brazilian coastal forests.O presente trabalho procura, numa abordagem essencialmente ecossistêmica, resituar o problema da matéria orgânica do solo sob seu aspecto interativo maior: o das interrelações vegetação/solo. O estudo macro-morfológico dos tipos de húmus em alguns ecossistemas de Florestas Costeira Intertropical é situado em relação as diferentes abordagens e resultados da bibliografia sobre matéria orgânica de solos florestais. São, assim, explicitadas as diferentes utilizações da noção de húmus subjacentes a diversas pesquisas, para apresentar posteriormente nossos resultados sobre a estrutura macromorfológica e a classificação de húmus de Restinga e de Floresta Atlântica. Estes resultados contradizem a hipótese geralmente admitida, segundo a qual em região tropical a rápida decomposição dos restos foliares determina estruturas húmicas de tipo mull. A dinâmica do processo interativo entre o substrato mineral, os aportes foliares e os agentes biológicos microrganismos e fauna é analisada, a fim de elucidar os fatores que determinam a diversidade de húmus em florestas costeiras

Simultaneous Measurement Of Electrical And Thermal Properties: Application To Margarine

An experimental set-up for simultaneous measurement of thermal and dielectric properties of pasty materials, and in particular of margarine is proposed. The objective of the study was to observe simultaneously how the above mentioned properties change when margarine undergoes temperature changes within a temperature range that also encompasses its melting point. The PVDF pyroelectric sensor in combination with the plane plate capacitor was used for simultaneous measurement avoiding thereby problems arising from differences in both, sample's quantity and specific portion taken, the illumination level, heating, etc. As result of temperature variations both, the electrical and thermal properties of margarine were shown very sensitive to the structural changes. The reversibility of the modification process was observed. The results obtained with the set-up for simultaneous measurements were compared to those acquired by the methods capable of measuring each of the two properties separately. © EDP Sciences.125849852Pudney, P.D.A., Hancewicz, T.M., Cunningham, D.G., (2002) Spectrosc-int J, 16, p. 217Van Dalen, G., (2002) J Microsc-oxford, 208 (2), p. 116Benzo, Z., Marcano, E., Gomez, C., (2002) J AOAC Int, 85 (4), p. 967Sacchi, R., Addeo, F., Musso, S.S., (1995) Ital J Food Sci, 7 (1), p. 27Dadarlat, D., Gibkes, J., Bicanic, D., (1996) J Food Eng, 30 (1-2), p. 155De Pereira, J.R., Da Silva, E.C., Mansanares, A.M., Miranda, L.C.M., (2001) Analytical Sci., 17, p. 172Longuemart, S., Quiroz, A.G., Dadarlat, D., Sahraoui, A.H., Kolinsky, C., Buisine, J.M., Da Silva, E.C., Neamtu, C., (2002) Instrum.

The Rio Games Legacy in Mobility: Challenges Beyond Infrastructure

The City of Rio de Janeiro, Brazil, a city of 6.5 million inhabitants, had several years to plan, invest, and prepare for the 2016 Olympic and Paralympic Games. A significant part of these efforts were in mobility infrastructure and operations, as they would become a fundamental legacy for the city. Silva, Maiolino and Torres, who were involved in these efforts in various capacities, discuss this experience and some of the challenges that go beyond investments in infrastructure such as behavior and operational changes

Quality Of Life In Patients With Parkinson's Disease And Their Caregivers' Stress Levels

Introduction. The quality of life in patients with Parkinson's disease (PD) is related to the disease level, which also indicates the caregiver's quality of life. Methods. This study comprised 43 patients with PD (31 male) and their respective caregivers (35 female) in order to evaluate if these disease symptoms may change their quality of life. Results. There was a statistically significant correlation between quality of life and the disease level and caregiver stress. The higher the score of disease level, the worse the patients and caregivers' quality of life. Conclusion. The disease control improves the patients' quality of life and, consequently, the caregivers' quality of life.162113117Quagliato, L.B., Viana, M.A., Quagliato, E.M.A.B., Simis, S., Alterações do olfato na doença de Parkinson (2007) Arq Neuropsiq, 65 (3 A), pp. 647-652Anderson, R., Bury, M., (1988) Living with chronic illness: The experience of patients and their families, pp. 88-116. , London: Allen & UnwinJacoby, A., Backer, G.A., Smith, D.F., Dewey, M.E., Chadwick, D.W., Measuring the impact of epilepsy: The development of a novel scale (1993) Epi Res, 16, pp. 83-88Price, B., Illness cares: The chronic illness experience (1996) J Adv Nurs, 24, pp. 275-279Lima, S.S.P., Quagliato, E.M.A.B., Cagliari, L.C., Souza, E.A.P., (1997) Linguagem e isolamento social no Mal de Parkinson, 1 (2), pp. 5-13. , Rev Soc Bras FonoaudiolGray, A., McNamara, I., Aziz, T., Gregory, R., Bain, P., Wilson, J., Quality of life outcomes following surgical treatment of Parkinson's disease (2002) Mov Disord, 17 (1), pp. 68-75Silva EG, Viana MA, Quagliato EMAB.

Pulpal and Periapical response after restoration of deep cavities in dogs' teeth with filtek silorane and filtek supreme xt systems.

Abstract OBJECTIVE: This study evaluated, histopathologically, the pulpal and periapical response to a silorane-based resin (Filtek Silorane) and a methacrylate-based nanoparticle resin (Filtek Supreme XT) in deep cavities in dogs, having zinc oxide and eugenol-based cement (ZOE) as a control. METHODS: The tooth/bone blocks were collected after 10 and 90 days and processed for microscopic analysis of the dentin, pulp, and periapical tissues using a score system. Data were analyzed statistically by Kruskal-Wallis and Dunn post-test (α=0.05). RESULTS: At 10 days, the pulp, connective tissue, and periodontal ligament showed normal characteristics. No resorption areas were observed. Both resins caused significantly less (p<0.05) periapical and pulpal inflammatory response than ZOE. At 90 days, for all materials, the connective pulp tissue was healthy and dense, with a normal blood vessel system. The apical and periapical region had normal structure and thickness. CONCLUSIONS: The use of the Filtek Silorane and the Filtek Supreme XT resins caused no adverse pulpal and periapical reactions after restoration of deep dentin cavities in vivo

The role of structural evolution on the quantum conductance behavior of gold nanowires during stretching

Gold nanowires generated by mechanical stretching have been shown to adopt only three kinds of configurations where their atomic arrangements adjust such that either the [100], [111] or [110] zone axes lie parallel to the elongation direction. We have analyzed the relationship between structural rearrangements and electronic transport behavior during the elongation of Au nanowires for each of the three possibilities. We have used two independent experiments to tackle this problem, high resolution transmission high resolution electron microscopy to observe the atomic structure and a mechanically controlled break junction to measure the transport properties. We have estimated the conductance of nanowires using a theoretical method based on the extended H\"uckel theory that takes into account the atom species and their positions. Aided by these calculations, we have consistently connected both sets of experimental results and modeled the evolution process of gold nanowires whose conductance lies within the first and third conductance quanta. We have also presented evidence that carbon acts as a contaminant, lowering the conductance of one-atom-thick wires.Comment: 10 page

Carcass characteristics and meat quality of sheep fed buffelgrass silage to replace corn silage

The aim of the study was to evaluate the carcass characteristics, proximate composition, and sensorial attributes of meat from sheep fed diets in which buffelgrass silage replaced corn silage. Thirty-two intact male crossbred Santa Inês sheep with an average live weight of 20.09 ± 2.0 kg were housed in individual stalls and allotted at random to four treatments in which corn silage was replaced by buffelgrass silage at the levels of 0 (control), 33.3%, 66.6%, and 100%. After an adaption period of 10 days, the sheep were fed for an additional 61 days. Feed was offered ad libitum and corn silage comprised 60% of the diet for the control group. Carcass characteristics, non-carcass components and meat quality were evaluated. Hot carcass yield, cold carcass yield, true carcass yield, trimmings, fat weight, and mesenteric and omental fat weight were highest for the control group (P &lt;0.05). Loin eye area had a quadratic response (P =0.02), with the largest areas being observed in animals fed the diet containing 66.6% buffelgrass silage. Liver weight (P &lt;0.01), luminosity of the meat (P &lt;0.05), and cooking loss (P &lt;0.05) likewise had nonlinear responses to the concentration of buffelgrass silage in the diet. The treatments did not have significant negative influence on the nutritional and organoleptic characteristics of the meat

Heavy-ion Physics at a Fixed-Target Experiment Using the LHC Proton and Lead Beams (AFTER@LHC): Feasibility Studies for Quarkonium and Drell-Yan Production

We outline the case for heavy-ion-physics studies using the multi-TeV lead LHC beams in the fixed-target mode. After a brief contextual reminder, we detail the possible contributions of AFTER@LHC to heavy-ion physics with a specific emphasis on quarkonia. We then present performance simulations for a selection of observables. These show that $\varUpsilon (nS)$ , $J/\psi$ and $\psi (2S)$ production in heavy-ion collisions can be studied in new energy and rapidity domains with the LHCb and ALICE detectors. We also discuss the relevance to analyse the Drell–Yan pair production in asymmetric nucleus–nucleus collisions to study the factorisation of the nuclear modification of partonic densities and of further quarkonium states to restore their status of golden probes of the quark–gluon plasma formation.Peer Reviewe
