Abstract: the accomplishment of the transit social function goes necessarily through the fulfillment of its participants' demands of accessibility, mobility and quality of life. mobility includes the ease of people and properties movement in the city in terms of the complex activities carried out, composing a component of the quality of life wanted by its residents. problems in infrastructure and transportation quality compromise the mobility. accessibility constitutes the ease, related to distance, time and cost, in reaching the desired destination, comprehending the effectiveness of the transport system as connecting separated locations. it reflects a relationship between people and space directly related to the citizens' quality of life. talking about quality of life in traffic necessarily needs to investigate the transport system of cities, especially the collective, in order to discuss its influence on the configuration of urban design, and the consequent impact on the accessibility and mobility of social actors

Abstract: The antimicrobial activity of four labdane-type diterpenes isolated from the oleoresin of Copaifera langsdorffii as well as of two commercially available diterpenes (sclareol and manool) was investigated against a representative panel of microorganisms responsible for periodontitis. Among all the evaluated compounds, (?)-copalic acid (CA) was the most active, displaying a very promising MIC value (3.1 μg mL?1; 10.2 μM) against the key pathogen (Porphyromonas gingivalis) involved in this infectious disease. Moreover, CA did not exhibit cytotoxicity when tested in human fibroblasts. Time-kill curve assays performed with CA against P. gingivalis revealed that this compound only inhibited the growth of the inoculums in the first 12 h (bacteriostatic effect). However, its bactericidal effect was clearly noted thereafter (between 12 and 24 h). It was also possible to verify an additive effect when CA and chlorhexidine dihydrochloride (CHD, positive control) were associated at their MBC values. The time curve profile resulting from this combination showed that this association needed only six hours for the bactericidal effect to be noted. In summary, CA has shown to be an important metabolite for the control of periodontal diseases. Moreover, the use of standardized extracts based on copaiba oleoresin with high CA contents can be an important strategy in the development of novel oral care products.

Abstract: Dunnigan-type partial lipodystrophy, which is characterized by a number of metabolic alterations, change in body fat distribution, and autosomal dominant inheritance pattern, is rare in the general population. Objective: To report the case of an adolescent with clinical and laboratory findings suggestive of Dunnigan-type partial lipodystrophy. Methods: Case report and literature review. Results: A 15-year-old adolescent presented at the clinic complaining of darkening of skin folds on her trunk and back. During physical examination, the presence of serious acanthosis nigricans in her cervical region, axillae, and intergluteal space was noted. Hirsutism in androgen-dependent areas was also observed, as well as relevant reduction of subcutaneous adipose tissue in the limbs, gluteal region, abdomen, and trunk and fat accumulation in the face and chin. Discussion. Dunnigan-type familial partial lipodystrophy is a rare dominant autosomal disease resulting from a heterozygous missense mutation in the LMNA gene, known as LPF type 2 (Dunnigan variant), which encodes the nuclear protein A/C-type lamin. It is characterized by the progressive disappearance of the subcutaneous adipose tissue in the limbs, gluteal region, abdomen, and trunk, with onset in puberty, followed by fat accumulation in other areas such as the face, chin, labia majora, and intra-abdominal region, leading to hypertrophy that may mimic the Cushing’s syndrome phenotype. Affected patients display marked insulin resistance and may consequently develop diabetes mellitus, acanthosis nigricans, hirsutism, and polycystic ovary syndrome. Conclusion: This case report highlights the importance of suspecting Dunnigan-type familial partial lipodystrophy in clinical practice. Early clinical diagnosis allows for measures that minimize the severe metabolic disorders associated with this disease and, consequently, these adolescents’ self-esteem issues.

Abstract: objective: the aim of this study was to determine changes in lean body mass after bariatric surgery. methods: this retrospective study reviewed 17 medical records of obese women who underwent banded roux-en-y gastric bypass. the medical records contained data collected immediately before and 1, 3, 6 and 12 months after surgery. the data included age, weight, height and lean and fat body mass determined by bioelectrical impedance analysis. results: the mean age of the patients was 43.1 years (sd=7.7). body mass index decreased significantly within 12 months of the surgery, going from 51.2 (40.2-74.1) to 33.7 (24.8-53.4)kg/m2, as did fat body mass, going from 67.5 (51.2-67.4) to 32.1 (16.4-61.9)kg. in the first month after surgery, lean body mass decreased from m=65.3 (sd=7.6) to m=59.7 (sd=8.1kg), representing a decrease of 8.5%. lean body mass remained constant after this period. conclusion: loss of lean body mass may indicate a change in protein metabolism immediately after bariatric surgery, which may result in an unfavorable clinical and nutritional course.

Abstract: the objective of this study was to identify, classify and describe the ontogenetic stages and/or size classes of three tropical palm species, astrocaryum aculeatissimum (schott) burret, euterpe edulis mart. and geonoma schottiana mart. the populations were sampled in five fragments of atlantic rain forest in 2005. all individuals had their diameter and height measured, and also the number and kind of leaf recorded in each fragment of nine 30 × 30 m plots. based on these measurements, we assigned each individual to one of five classes. astrocaryum aculeatissimum and e. edulis change their kind of leaf throughout development. geonoma schottiana has a high variation in the kind of leaf, and only the seedlings stage displays only one kind of leaf. the appearance of stem and reproductive events also represents class change. the kind of leaf, the surge of the stem and reproductive events were the main characteristics used for the ontogenetic stage identification. however, for e. edulis and g. schottiana class identification, we also used quantitative characteristic because some stages have wide size variation. studies that characterize and describe species ontogenetic stages are very important for standardization and to allow comparison between studies of population structure and dynamics.

Abstract: in order to understand whether and how population structure of different species varies among different fragments and within the same fragment, we studied the ontogenetic stage and size distributions of two common "cerrado" tree species, in four "cerrado" fragments with different physiognomies and in three sites with similar physiognomies within the same fragment in the municipality of itirapina (22°15' s, 47°48' w), s?o paulo state, se brazil. we recorded the height and the stem basal diameter (dsh) of all individuals with dsh > 3 cm in the six samples of 200 contiguous 5 x 5 m plots. individuals with dsh < 3cm were sampled in 1 m2 sub-plots at one corner of the plots. xylopia aromatica had greater proportions of initial ontogenetic stages in open physiognomies, whereas roupala montana had high proportion of initial stages and greater young:adult ratio in the densest physiognomy. the ontogenetic stage structure had greater differences among samples within the same fragment than among fragments, i.e., it varied in small spatial scales. the spatial heterogeneity of environmental factors (differences in vegetation cover that varied from open to dense), different reproductive characteristics (r. montana can reproduce asexually, whereas x. aromatica reproduces only by seeds) and phenological patterns (annual in x. aromatica, and supra-annual in r. montana) could be the main variables associated to the ontogenetic structure variation, and they would act differently upon each species in each site. thus, each site of "cerrado" constitutes a different environment, which can differently influence the success of a species.

Abstract: nowadays, forests fragmentation is one of the main impacts in the natural communities and can lead to extinction of many species and modifications in many ecological processes. the present work aimed to evaluate the influence of the size and the edge of forest fragments in the production and accumulation of litter and in the canopy openness of four different-size forest fragments of the atlantic forest. the litter production was bigger in the larger fragment (8.90 t ha-1 year-1 in the interior and 8.76 t ha-1 year-1 in the edge) than in the three smaller fragments (7.29 t ha-1 year-1 in the interior and 7.27 t ha-1 year-1 in the edge), however the thickness of the litter layer deposited on the ground and the canopy openness of the forest had no relation with the size of the fragments. no difference was found in the production and accumulation of litter and canopy openness between areas of edge and interior. the dry season had a direct influence in the increase of the litter production. concerning the fragment area, we can infer that the difference between litterfall and accumulation on the ground might be related with the greater decomposition rates in the larger fragment, due to the higher humidity. no relation between litter production and canopy openness was found, probably because of the great spatial heterogeity caused by the frequency of gap formation and structural complexity and deciduousness of the forest.
