Abstract: introduction: hiv-seropositive patients have shown changes in body composition such as lipoatrophy in certain regions of the body and lipohypertrophy in others, representing characteristics of lipodystrophy syndrome. it is important to monitor the quantity of fat per body segment using practical and low-cost methods in order to optimize the treatment of this group. objectives: to correlate the body composition per body segment obtained by anthropometric measurements and by segmental bioelectrical impedance with dxa in hiv-seropositive patients on antiretroviral treatment methods: we measured circumferences (arm, waist, hip, thigh and calf) and skinfolds (biceps, triceps, subscapular, suprailiac) and performed segmental bioelectrical impedance (bia) analysis and dxa. the pearson test was used to determine correlations and the st. laurent test was used to assess concordance between variables. results: we evaluated 26 patients, 35% of whom were overweight. the triceps skinfold (tsf), waist circumference (wc) and thigh circumference (tc) were significantly correlated with the measurement obtained by the gold standard (p<0.01). there was no concordance between the values obtained by segmental bia and by dxa. conclusions: anthropometric measurements such as tsf, wc and tc are importantfor the monitoring of changes in body composition among hiv-seropositive patients on antiretroviral treatment. segmental bia did not prove to be appropriate for the assessment of body composition in hiv-seropositive patients.

Abstract: Pastagens cultivadas, de maneira geral, entram em processo de declínio, associado à infesta o de plantas daninhas, cujo manejo exitoso come a com o levantamento das espécies infestantes e sua biologia. Este trabalho teve como objetivo o estudo fitossociológico, nas esta es chuvosa e seca, em duas pastagens cultivadas de Brachiaria (Urochloa) spp., com gado (AI) e sem gado (AII), em áreas de Cerrado do Mato Grosso do Sul. Foi constatada a ocorrência de 104 espécies de plantas daninhas herbáceas e subarbustivas de Fanerógamas. As famílias de maior destaque, em número de espécies, foram Fabaceae (23 espécies), Poaceae (16) e Asteraceae (15). As hemicriptófitas predominam com 41% das espécies. As espécies com maiores valores de importancia e cobertura relativa s o B. decumbens e Sida rhombifolia, em AI, e B. brizantha e Desmodium incanum, em AII, além de Paspalum notatum, em ambas as pastagens. Os valores de diversidade de Shannon foram 4,19 e 4,43 nats, para AI e AII, respectivamente, indicando considerável riqueza de espécies. O índice de dissimilaridade florística entre AI e AII, obtido a partir da Distancia Euclidiana, é 0,7468, o que indica poucas espécies em comum (44%). Na esta o seca, o número de espécies em AI caiu 10% e, em AII, aumentou 4%. PALAVRAS-CHAVE: Agroecossistema; Brachiaria; ecologia vegetal; flora; Urochloa. Cultivated pastures, in general, go through a decline process, associated with the occurrence of weeds, whose successful management begins with the survey of species and their biology. This study aimed to carry out phytosociological surveys, during the rainy and dry seasons, in two pastures cultivated with Brachiaria (Urochloa) spp., with cattle (AI) and without cattle (AII), in Cerrado (Brazilian savanna) areas of the Mato Grosso do Sul State, Brazil. The occurrence of 104 weedy herbaceous and subshrubby Phanerogams species was recorded. The families with the highest number of species were Fabaceae (23 species), Poaceae (16), and Asteraceae (15). Hemicryptophytes predominate with 41% of the species. The species with the highest importance value and relative coverage are

Abstract: The objective of the present study was to verify the effects of two frequencies (100 and 33%) of knowledge of results (KR) on the learning of a motor skill, in individuals with Down syndrome (DS). Twenty participants with DS were randomly assigned into two groups. While the 100% group received KR after each trials, the 33% group received KR in a third of the trials. The task consisted of throwing an implement on a target, with the dominant hand, while blindfolded. The acquisition phase consisted of 30 practice trials, while the retention phase, performed after 48 hours later, consisted of 10 trials without KR. The results showed no differences between the groups. We concluded that reduced relative frequencies of KR are as effective as high frequencies on the learning of simple motor tasks in adults with DS.

Abstract: due to the importance of cercopids as pests in sugarcane and forage grass, researches have been conducted in order to address aspects related to the bioecology and control of these insects. the objective of this study was to develop a rearing technique for mahanarva fimbriolata (st?l) (hemiptera: cercopidae) on sugarcane, in the laboratory (25 ± 1oc; 70 ± 10% rh; and 14-hour photophase). adults were isolated in cylindrical cages containing one sugarcane plant, with a moistened cotton disc surrounding the base of the plant as a site for oviposition. eggs were removed from the cotton disc by washing it in running water over sieves and maintained in petri dishes on moistened filter paper until the nymphs hatched. the newly hatched nymphs were transferred to sugarcane roots and placed into boxes with lids, to keep a moistened and dark environment favoring their development and maintaining the root system, providing food access to the developing nymphs. this method allowed m. fimbriolata to be maintained in laboratory conditions throughout the year, which would certainly foster research on this insect.
