Abstract: primary angiosarcoma of bone is rare and accounts for less than 1% of all angiosarcomas(4). vascular bone neoplasms represent 1,4% of primary malignant bone tumors. the authors describe an unusual case of bone angiosarcoma located in the spine. the diagnosis was initially hemangioendothelioma, a borderline endothelial vascular tumor, as stated by stout(11). the lesion was treated by local embolization and radiation therapy. the tumor recurred locally ten years later as a high-grade angiosarcoma, showing epithelioid features, which indicates tumor progression. immunohistochemical studies were positive for vascular markers such as factor viii, cd31 and cd 34. the patient developed lung metastasis. i was not observed in the literature any other case with ten-year follow-up and tumor progression with epithelioid features.
Physics teaching and visual deficiency: learning activities about the concept of acceleration of gravity
Eder Pires de Camargo,Dirceu da Silva,Jomar de Barros Filho
Investiga??es em Ensino de Ciências , 2006,
Abstract: In this paper we present the analysis of two physics teaching activities that were developed for and applied in a group of visually impaired students. The content of the activities was focused on the concept of gravitational acceleration. In the first activity the concept was explored by means of the movement of an object in an inclined plane; in the second, it was explored through the movement of a metallic disk inside a tube. Both experimental setting emitted audible signals. In this sense, all the “observational” practice were based in the audible perception of the gravitational phenomena, which permitted discussion among the students, in small groups, and a debate aiming at a general conclusion. The analysis of the data was based in a category labeled “comprehension”, which illuminated some attitudes of the students throughout the experiments such as: the sharing of ideas, the defense and arguing of meanings, and the reconstruction of meanings. As conclusions we can say that the activities were valuable for motivating the students and for giving to them some background for: (1) performing experiments; (2) observing a phenomena through an audible via; (3) collecting and analyzing data related to the variation of speed; (4) sharing, arguing and reformulating hypothesis during the discussions.

Abstract: the aim of this study was to evaluate the germinative behavior of bacccharis retusa and tibouchina multiflora, species that occur in the "canga" vegetation of the quadrilátero ferrífero of minas gerais. diaspores collected in the county bar?o de cocais were placed to germinate under the temperatures of 15, 20, 25 and 30 oc at continuous light or in darkness condition. the diaspores initially remained under darkness were later transferred to light presence maintaining the same temperatures. diaspores of both species presented a positive photoblastic behavior, with inexpressive germination under darkness in all tested temperatures. in presence of continuous light, seeds of t. multiflora showed no difference in the percentage of germination in all temperatures, while b. retusa showed lower germination at 30 oc. diaspores initially maintained under darkness germinated rapidly after transferred to continuous light. however, no indication of significant effect of the dark period was observed in values of the final germination percentage in each temperature tested. these results suggest that these two "canga" species may have potential to constitute the soil seed bank.

Abstract: Introduction: Mental exercise using the mirror therapy (MT) improves the retention of newly acquired skills and the performance of sequential motor skills in subjects with post-stroke hemiparesis. Objectives: The study aimed to analyze the mirror therapy effect on the range of motion and the lower limb functionality in post-stroke hemiparesis subjects. Materials and Methods: Eleven participants with hemiparesis in the lower limb were subjected to the 10 sessions of a MT protocol. The interventions were three times per week per 30 minutes each day. Evaluation of active and passive ankle goniometry (dorsiflexion and eversion movements); Ascent and Descent Ladder Rate (ADLR); Time Up and Go test (TUG test); EFEI scale; and FAAM scale were performed. The data were collected before and after the intervention using MT, and then statistically compared. Results: The MT improved significantly (p < 0.01) the range of motion of the paretic lower limb both evaluated by active and passive ankle goniometry. An increase in the speed of gait and other functional tasks related to the paretic lower limbs were found through the TUG and ADLR tests. It also demonstrated a positive influence on the functionality of the paretic lower limb motor control through the analysis of the scores in the FAAM and EFEI scales. Conclusion: It is concluded that the MT therapy can help the patients with post-stroke hemiparesis in the improvement of several functions. Probably, the mirror therapy would aid in the repair of the injuries in the cortical areas.
