Gama, Lucilene Umbelino;Barbosa, Ana Angélica Almeida;Oliveira, Paulo Eugênio Alves Macedo de;
Brazilian Journal of Botany , 2011, DOI: 10.1590/S0100-84042011000300011
Abstract: pouteria ramiflora and p. torta are tree species sympatric in the cerrado and were studied in the natural reserve of clube ca?a e pesca itororó (uberlandia-mg) in order to compare various aspects of their reproductive biology. the phenophases were evaluated weekly and their intensity was quantified. the floral biology, breeding system, sexual system and floral visitors were studied in the field and/or laboratory. in both species, leaf fall occurred in the end of the dry season, leaf flushing between the dry and the rainy season, flowering in the dry season and fruit maturation during the rainy season. they have tubular small greenish flowers, with small amounts of nectar and high pollen viability. they are self-sterile, non-agamospermic and had low fruiting success from natural pollination. p. torta is a hermaphrodite species, with protogynous and hercogamous flowers, while p. ramiflora is morphologically gynomonoecious but functionally unisexual. the apparently low pollen flow and the abortion of young fruits resulted in low fruit set from natural pollinations. both species are visited by several small insects, including butterflies, moths, flies and bees.

Online Brazilian Journal of Nursing , 2012,
Abstract: Vitamin C is empirically used by nurses to unblock long-term venous catheters. The study aims at analyzing the action of vitamin C in the coagulation process, establishing an in vitro coagulation model and fibrinolysis. It is an in vitro experimental study of the total blood of 10 healthy volunteers and 13 pools of citrated plasma. The results showed reduction of serum D-dimer with statistical significance when treated with vitamin C before and after clot formation. The weight of clots in blood presented significant reduction only when treated with vitamin C before the clotting process. However, when using vitamin C after clot formation a change is noticed in its structure and consistency. There were no significant differences in the weight of fibrin clots. It was concluded that vitamin C acts with greater intensity during the pre-clot formation phase and with less intensity in the two subsequent hours.

An unusual case of an isolated capitellar fracture of the right elbow in a child: a case report

Journal of Medical Case Reports , 2012, DOI: 10.1186/1752-1947-6-57
Abstract: We present the case of an 11-year-old Portuguese girl with a displaced fracture of the capitellum of the right elbow, a typical Hahn-Steinthal or Type 1 fracture, which was followed for one year. The treatment and outcome of this fracture are described. Our patient underwent an open reduction and internal fixation with two cannulated screws. There were no complications and normal elbow function was recovered.The authors believe that cannulated screw fixation is a reliable method of treatment for Type 1 capitellar fracture in children because it enables good interfragmentary compression, early mobilization, faster functional elbow recovery and implant removal is rarely necessary.Isolated capitellar fractures are rare and represent only 1% of all elbow fractures and 6% of distal humeral fractures [1-3]. In children under the age of 12, these fractures are even more unusual and, to the best of our knowledge, such an injury has not been reported in a young child [3-8]. The mostly cartilaginous composition of the capitellum below that age makes it more resistant to stress. Therefore, a fall on the outstretched hand (which is the mechanism of injury in most of these cases) is more likely to produce a supracondylar or lateral condylar fracture. As the capitellum grows and ossifies in older children, it becomes more susceptible to shear injury [5,9]. Fracture of the lateral humeral condyle is usually seen at a younger age group and may be confused with a fracture of the capitellum. A fracture of the capitellum is an osteochondral fracture and is entirely intra-articular. The epicondyle, the growth plate and the metaphysis are not involved, and the posterior part of the lateral condyle remains intact. Differentiation between a fracture of the lateral humeral condyle and a capitellar fracture is important with respect to treatment [7,8].The presently accepted classification systems of capitellar fractures are descriptive and not treatment-directed [10].

Violência e identifica??o de ra?a como consequência da categoriza??o de grupo
Gon?alves, Diego Macedo;
Estudos de Psicologia (Natal) , 2010, DOI: 10.1590/S1413-294X2010000100013
Abstract: evolutionary psychology has shown that collective aggression toward out-group members in some specific situations, is part of the human behavioral repertoire. the human mind contains mechanisms designed for the formation of alliances and coalitions. this psychological mechanism, called "us versus them", influences individuals to assume a contrary or a favorable attitude in relation to a given group and may generate violent conflicts. one way whereby this mental process is manifested is through race categorization. the human being uses various cues to categorize groups, among them skin color. this is a plastic and dynamic process, which can change depending on the social context.

Abstract: there are discrepancies in the literature regarding time trends in the occurrence of asthma in adults. this study compared asthma prevalence in two cross-sectional studies with a ten-year interval in pelotas, rio grande do sul state, brazil. the first, in 2000, included 1,968 individuals, and the second, in 2010, 2,466 adults (20-69 years). prevalence of wheezing and shortness of breath in the prior 12 months remained the same after ten years (6% and 6.1%, respectively). in both studies, asthma was more frequent among females and people with low family income. physician-diagnosed asthma increased by 35.6%, and lifetime incidence of asthma, by 32.2%. there was no percentage change in current asthma symptoms or current asthma. local socioeconomic improvement between the two studies was consistent with the increase in medical diagnosis, but did not reflect better management of asthma symptoms, underlining the need for investment regarding other determinants of the disease.

Abstract: this study was carried out to evaluate the profile of aflatoxin contamination distribution among packages of peanut candies trading. aflatoxin occurrence and distribution date from this study suggest that sampling plans to aflatoxin detection in processed products are always associated with high degree of uncertain of presence or not and of the true average level of contamination. to improve sampling plans it is necessary to consider the differences among product types. there are processed products whose the raw material is grounded, like "pa?oca" and other that it is not, like "amendoim japonês". occurrence and distribution of aflatoxin contamination among packages in lots of "pa?oca" was more homogeneus than in lots of "amendoim japonês".

Abstract: "alho-macho" (sisyrinchium platense johnst.) is a native plant occurring on natural pasture at the southwestern region of rio grande do sul, brazil, on heavy clay black soils with poor drainage, specially when these were modified by cultivation. in these grassland areas livestock breeding, alone or associated to agriculture, have a great economic importance. cattle do not graze s. platense, and the natural desirable plants are usually replaced by this species and may restrict the potencial gains in animal production. aiming to evaluate the effects of clipping once, twice and four times in controlling this plant, an experiment in a randomized complete block design was carried out in two geographical situations of a natural pasture, during three years. the results showed a decrease mean of 55% on foliage cover of "alho-macho" when clipping once, twice or four times on wet areas. in dry areas the decrease on foliage cover mean was 30,7% when clipping once or twice.
