    Food-borne parasite infections affect communities worldwide by transmitting microorganisms, imposing a serious risk to human and animal health. The aim of this study was to analyze the parasitological contamination in cress (Nasturtium officinale, Barbarea verna e Lepidium sativum) from various establishments in the metropolitan area of Curitiba, State of Parana. We analyzed 50 cress samples using the wash and centrifugation technique and the sedimentation method. Among the samples, 6 presented trophozoites of Balantidium coli, cyst of Entamoeba coli and parasites of Stronylidae and Trichuridae Family and 14 samples were contaminated with maggots, slugs and snails. Factors related to this parasitological contamination may be the failure in the quality of water used for irrigation, and the planting, storage and the distribution of the plants. As these vegetables are mainly eaten in natura, we recommend the inclusion of safety procedures along the entire process to protect the health of consumers, since vegetables  can be a zoonosis transmitter vehicle. Food-borne parasite infections affect communities worldwide by transmitting microorganisms, imposing a serious risk to human and animal health.

    Background: Hypertension is a clinical condition highly prevalent in the elderly, imposing great risks to cardiovascular diseases and loss of quality of life. Current guidelines emphasize the importance of nonpharmacological strategies as a first-line approach to lower blood pressure. Exercise is an efficient lifestyle tool that can benefit a myriad of health-related outcomes, including blood pressure control, in older adults. We herein report the protocol of the HAEL Study, which aims to evaluate the efficacy of a pragmatic combined exercise training compared with a health education program on ambulatory blood pressure and other health-related outcomes in older individuals. Methods: Randomized, single-blinded, multicenter, two-arm, parallel, superiority trial. A total of 184 subjects (92/center), ≥60 years of age, with no recent history of cardiovascular events, will be randomized on a 1:1 ratio to 12-week interventions consisting either of a combined exercise (aerobic and strength) training, three times per week, or an active-control group receiving health education intervention, once a week. Ambulatory (primary outcome) and office blood pressures, cardiorespiratory fitness and endothelial function, together with quality of life, functional fitness and autonomic control will be measured in before and after intervention. Discussion: Our conceptual hypothesis is that combined training intervention will reduce ambulatory blood pressure in comparison with health education group. Using a superiority framework, analysis plan prespecifies an intention-to-treat approach, per protocol criteria, subgroups analysis, and handling of missing data. The trial is recruiting since September 2017. Finally, this study was designed to adhere to data sharing practices. Trial registration: NCT03264443. Registered on 29 August, 2017

    Se describe a Magallanodon baikashkenke gen. et. sp. nov., un nuevo mamífero gondwanaterio del Cretácico tardío de la Región de Magallanes, en el sur de Chile (Valle del Río de Las Chinas, Estancia Cerro Guido, norte de Puerto Natales, Provincia de Última Esperanza). Las capas portadoras se ubican entre los niveles del Campaniano tardío-Maastrichtiano temprano de la Formación Dorotea (Cuenca de Magallanes/Austral). Los nuevos restos constituyen el registro más austral de un mamífero gondwanaterio del Mesozoico, como así también el primer mamífero Mesozoico conocido para Chile. El nuevo taxón es comparable en tamaño a las formas hipsodontes Gondwanatherium (Cretácico tardío) y Sudamerica (Paleoceno temprano), pero con molares notoriamente braquidontes soportados por cuatro a cinco raíces. Como en otros gondwanaterios, posee al menos un incisivo superior rodentiforme en la serie superior. Se diagnostica y describe brevemente el nuevo taxón, considerado tentativamente como un ferugliotérido (Ferugliotheriidae). De confirmarse esta asignación, este nuevo taxón representaría el miembro de mayor tamaño para la familia. El patrón oclusal de los molariformes, con el desgaste, se semeja también al de otros gondwanaterios, en particular al de los ferugliotéridos y al del sudamerícido Gondwanatherium, agregando en consecuencia más evidencias en favor de la proximidad filogenética entre ambas familias. Se llevó a cabo un análisis de la microestructura del esmalte del incisivo superior de Magallanodon; como resultado, se encontraron varias similitudes importantes con el patrón existente en Gondwanatherium (Sudamericidae). Se discute la significación de Magallanodon en la adquisición, entre los gondwanaterios, de un patrón molariforme caracterizado por la presencia de lofos transversos. Finalmente, se discute la significación del nuevo hallazgo en el contexto de las biotas australes, incluyendo aquellas de Patagonia y Antártica.We describe Magallanodon baikashkenke gen. et. sp. nov., a new gondwanatherian mammal from the Late Cretaceous of the Magallanes Region in southern Chile (Río de Las Chinas Valley, Estancia Cerro Guido, north of Puerto Natales city, Última Esperanza Province). The mammal-bearing layer is placed within the Late Campanian-Early Maastrichtian levels of the Dorotea Formation (Magallanes/ Austral Basin). The new remains constitute the southernmost record of a Mesozoic gondwanatherian mammal, as well as the first Mesozoic mammal from Chile. This taxon is comparable in size to the hypsodont-toothed Gondwanatherium (Late Cretaceous) and Sudamerica (Early Paleocene) but with noticeably brachyodont molariforms supported by four to five roots. As in other gondwanatherians, it has at least one hypertrophied, rodent-like incisor in the upper jaw. The new taxon is here diagnosed and described, and is regarded as a possible ferugliotheriid (?Ferugliotheriidae). If confirmed, it would represent the largest known taxon for this family. Its molariform occlusal crown pattern, after wear, resembles that of other gondwanatherians, particularly ferugliotheriids and that of the sudamericid Gondwanatherium. This adds new evidence on the phylogenetic proximity of ferugliotheriid and sudamericid gondwanatherians. An analysis of the enamel microstructure of the upper incisor of Magallanodon was performed demonstrating several crucial similarities with the pattern shown by Gondwanatherium (Sudamericidae). We discuss the significance of Magallanodon for understanding the acquisition, within gondwanatherians, of a lophed molariform pattern. Finally, we discuss the significance of the new finding in the context of southern biotas, including those of Patagonia and Antarctica.Fil: Goin, Francisco Javier. Universidad Nacional de La Plata.

    The South Shetland Islands, Antarctica: unified lithostratigraphy and geological map

    Get PDF
    Over the last few decades, numerous geological studies have been carried out in the South Shetland Islands, which have greatly contributed to a better understanding of its geological evolution. However, few attempts have been conducted to correlate the geological units throughout this archipelago. We present herein a lithostratigraphical correlation, which constitutes a coherent and unified stratigraphy for the main Mesozoic and Cenozoic units rocks of the South Shetland Islands along with a new geological map. The lithostratigraphical correlation shows that the geological evolution comprises three main stages: (i) deep marine sedimentation from ~164 to 140 Ma, (ii) subaerial volcanism and sedimentation with a proliferation of plants and fauna from ~140 to 35 Ma and (iii) glacial and interglacial deposits from ~35 Ma. The lithostratigraphical correlation also shows a broad geographical trend of decreasing age of volcanism from southwest to northeast, which has been previously suggested. However, this spatial age trend is disrupted by the presence of Eocene magmatism in Livingston Island, located in the centre of the archipelago. We suggest that the migration of volcanism occurred from the Late Cretaceous until the early Eocene. Subsequently, enhanced magmatic activity took place from the mid-Eocene until the Miocene, which we associate with processes related with the waning of subduction, such as roll-back. Finally, constraining the protolith age of the metamorphic complex of Smith Island remains challenging, yet holds key implications for the tectonic and accretionary evolution of the Antarctic Peninsula. The rocks recording the glaciation of this sector of Antarctica are well exposed in the northern South Shetland Islands and hold critical information for understanding the timings and processes that lead to the greenhouse-icehouse transition towards the Eocene end. Contemporaneous rocks to the breakup of Antarctic Peninsula from Patagonia, which led to the Drake Passage opening and the development of the Scotia Sea, are exposed in the north-centre of the archipelago. A better age constrain of these units may lead to further understanding the paleontological evolution of this region. The dataset containing the geological map is shared as a shapefile and KML file

    Aspectos da lesão do canto posterolateral do joelho

    O canto posterolateral (CPL) do joelho continua a ser um tópico de considerável discussão. A sua anatomia é complexa e o papel de cada componente é freqüentemente debatido. A lesão das estruturas do CPL resulta em instabilidade posterolateral do joelho. O mecanismo de lesão mais comum é o trauma direto na região anteromedial na perna de sustentação do peso. Na lesão sem contato uma combinação de força lateral e posterior no joelho estendido resulta em hiperextensão do joelho e rotação externa da tíbia. Os testes clínicos diagnósticos mais utilizados são a gaveta posterolateral e o recurvatum rotação externa. O ligamento popliteofibular é uma estrutura importante na limitação da translação posterior, do varo e da rotação externa da tíbia. A instabilidade posterolateral isolada é incomum e freqüentemente ocorre concomitante a lesões do ligamento cruzado anterior e principalmente do ligamento cruzado posterior. O tratamento da instabilidade resultante da lesão é difícil, em grande parte devido a complexa anatomia.O objetivo deste estudo é revisar alguns aspectos da lesão do canto posterolateral do joelho de forma a fornecer subsídios ao profissional da área de Educação Física.The posteroleral comer of the knee continues to be a topic of considerable discussion. Its anatomy is complex and the function of each component is often debated. Damage to the structures of the posterolateral corner results in posterolateral knee instability. The mechanism of injury to the posterolateral structures is most commonly a direct blow to anteromedial aspect of the weight-bearing lower leg. In noncontact injury, the mechanism often includes a combination o f lateral and posterior forces on an extended knee, resulting in hyperextension of knee and externalo rotation of the tibia. The popliteofibular ligament is an important structure of limitation of the posterior translation, varus and external rotation of the tibia. isolated posterolateral instability is uncommom but often occurs concomitant with injuries to the anterior cruciate ligament and more frequently to the posterior cruciate ligament. The treatment of the instability resulting from injury to posterolateral comer is difficult, largely because of the complex anatomy. The purpose of this study is to show to Physical Education professional some aspects of this injury. Key words: injury, posterolateral comer, popliteofibular ligament, treatment
