Abstract: Molecular lipid biomarkers (hydrocarbons, alcohols, sterols and fatty acids) and compound-specific isotope analysis of suspended particulate organic matter (SPM) and surface sediments of the Mackenzie Shelf and slope (southeast Beaufort Sea, Arctic Ocean) were studied in summer 2009. The concentrations of the molecular lipid markers, characteristic of known organic matter sources, were grouped and used as proxies to evaluate the relative importance of fresh algal, detrital algal, fossil, C3 terrestrial plants, bacterial and zooplankton material in the organic matter (OM) of this area. Fossil and detrital algal contributions were the major fractions of the freshwater SPM from the Mackenzie River with ~34% each of the total molecular biomarkers. Fresh algal, C3 terrestrial, bacterial and zooplanktonic components represented much lower percentages, 17, 10, 4 and <1%, respectively. In marine SPM from the Mackenzie slope, the major contributions were fresh and detrital algal components (>80%), with a minor contribution of fossil and C3 terrestrial biomarkers. Characterization of the sediments revealed a major sink of refractory algal material mixed with some fresh algal material, fossil hydrocarbons and a small input of C3 terrestrial sources. In particular, the sediments from the shelf and at the mouth of the Amundsen Gulf presented the highest contribution of detrital algal material (60–75%), whereas those from the slope contained the highest proportion of fossil (40%) and C3 terrestrial plant material (10%). Overall, considering that the detrital algal material is marine derived, autochthonous sources contributed more than allochthonous sources to the OM lipid pool. Using the ratio of an allochthonous biomarker (normalized to total organic carbon, TOC) found in the sediments to those measured at the river mouth water, we estimated that the fraction of terrestrial material preserved in the sediments accounted for 30–40% of the total carbon in the inner shelf sediments, 17% in the outer shelf and Amundsen Gulf and up to 25% in the slope sediments. These estimates are low compared to other studies conducted 5–20 yr earlier, and they support the increase in primary production during the last decade mainly because of the increase in the number of ice-free days and due to the strength and persistence of winds favouring upwelling.

Abstract:

The Tityus serrulatus scorpion is considered the most dangerous scorpion in Brazil and is responsible for several cases of human envenomation annually. In this study, we performed transcriptome profiling of the T. serrulatus venom gland. In addition to transcripts with housekeeping functions, such as those related to protein synthesis, energy supply and structural processes, transcripts from thirty-five families of venom peptides or proteins were identified. These transcripts included three new complete sequences of toxins and more than a dozen putative venom gland proteins/peptides. The venom gland transcriptome profile was verified by comparison with the previously determined proteomic profile. In conclusion, this transcriptome data provides novel insights into the putative mechanisms underlying the venomous character of T. serrulatus. The collected data of scorpion transcripts and proteins/peptides described herein may be an important resource for identifying candidate targets of molecular therapies and preventative measures.

Abstract: OBJECTIVES: The aim of this study was to assess the prevalence of Temporomandibular Disorders (TMD), using the Research Diagnostic Criteria for TMD (RDC/TMD) in women with episodic and chronic migraine (M and CM), as well as in asymptomatic women. METHOD: Sample consisted of 61 women, being 38 with M and 23 with CM, identified from a headache outpatient center; we also investigated 30 women without headaches for at least 3 months (women without headache group - WHG). Assessment of TMD was conducted by a physical therapist who was blind to the headache status. RESULTS: The prevalence of TMD, assessed through the RDC, was 33.3% in the WHG, 86.8% in the M group and 91.3% of the CM group. Differences were significant when comparing M and CM groups with WHG (p<0.001), but not when comparing M and CM (p>0.05) as well as higher risk for TMD [odds ratio (OR)=3.15, 95% confidence interval (CI) 1.73-5.71 and OR=3.97, 95%CI 1.76-8.94]. CONCLUSION: Women with migraine are more likely to have muscular and articular TMD, suggesting that both disorders might be clinically associated, which demonstrate the importance of physical therapy assessment in the multidisciplinary team. OBJETIVOS: Avaliar a presen a de disfun o temporomandibular (DTM) usando o Critério Diagnóstico em pesquisa para disfun o temporomandibular (RDC/TMD) em mulheres com migranea episódica e migranea cr nica (M e MC), bem como em mulheres sem nenhuma cefaleia. MéTODO: A amostra foi composta por 61 mulheres, 38 com M e 23 com MC, selecionadas em um centro terciário de saúde; também foram avaliadas 30 mulheres sem nenhuma cefaleia nos últimos três meses (grupo de mulheres sem cefaleia - MSC). A avalia o da DTM foi realizada por um fisioterapeuta que n o tinha conhecimento do diagnóstico das pacientes. RESULTADOS: Por meio do RDC/TMD, a frequência de DTM foi de 33.3% no grupo MSC, 86.8% no grupo M e 91.3% no grupo MC. A diferen a foi significativa entre os grupos com migranea e o grupo MSC (p<0.001), porém n o houve diferen a entre os grupos M e MC (p>0,05), bem como maior fator de risco de DTM [odds ratio (OR)=3,15, intervalo de confian a (IC) de 95% 1,73-5,71 e OR=3,97, IC95% 1,76-8,94]. CONCLUS O: Mulheres com migranea têm maior frequência de DTM muscular e articular, sugerindo que essas condi es est o clinicamente associadas, evidenciando a importancia do fisioterapeuta na equipe de avalia o multidisciplinar.

Abstract: this study analyses university students' value systems and the relationships among these systems and their attitudes towards democracy. two hundred and eighty-four university students from goiania (brazil) answered the psychosocial values questionnaire and the scale of attitudes towards democracy. schwartz's theory about motivational types of values and inglehart's theory on materialist and pos-materialist values were used to analyse the underlying dimensions of structure and content of students' value systems. the results showed that the values were organized according to four systems: hedonist, religious, materialist and pos-materialist. besides this, the results also indicated that adhesion to materialist values was negatively correlated to democracy while the adhesion to pos-materialist values contributes to a positive attitude towards democracy. the similarities among these results and previous studies are discussed.

Abstract: Este artigo analisa os sistemas de valores de estudantes universitários e a rela o desses sistemas com a atitude em rela o à democracia. Para tanto, aplicou-se o Questionário de Valores Psicossociais e a Escala de Atitudes em Rela o à Democracia a 284 estudantes de uma universidade da cidade de Goiania (Brasil). Na análise das dimens es subjacentes à estrutura e ao conteúdo dos sistemas de valores, considera-se a teoria de Schwartz sobre os tipos motivacionais e a teoria de Inglehart sobre os valores materialistas e pós-materialistas. Os resultados mostram que os valores se organizam em fun o de quatro sistemas: o hedonista, o religioso, o materialista e o pós-materialista. Constata-se também que a ades o aos valores materialistas contribui para uma atitude negativa em rela o à democracia, enquanto que a ades o aos valores pós-materialistas contribui para uma atitude positiva. A discuss o girou em torno da similaridade entre estes resultados e os obtidos em estudos anteriores.

Abstract: a comparative study between the biuret method (standard method for total proteins) and spectrophotometric methods using dyes (bradford, 3',3",5',5"-tetrabromophenolphthalein ethyl ester-tbpee, and erythrosin-b) was carried out for the determination of total proteins in blood plasma from rats. bradford method showed the highest sensitivity for proteins and biuret method showed the lowest. for all the methods, the absorbance for different proteins (bsa, casein, and egg albumin) was measured and bradford method showed the lowest variation of absorbance. the concentration of total protein obtained by using bradford method was not statistically different (p>0.05) from concentration of total protein obtained by the biuret method. but in regard to erythrosin-b and tbpee methods the concentrations of total protein were statistically different (p<0.05). thus, bradford method could be used instead of the biuret method for determination of total proteins in blood plasma.

Abstract: starch has very important physicochemical properties that depend on its botanical source and structural characteristics. peruvian carrot starch displays special characteristics, which make it appropriate for industrial application in many processed foods. in this work, starch from two peruvian carrot varieties, amarela de carandaí (ac) and amarela de senador amaral (asa), were isolated and their physicochemical and structural properties were determined. starch from the asa variety exhibited granules with a greater average diameter than those from the ac variety and more than double the number of granules with size >20 μm, when compared to the other variety. starches from both varieties, observed in a scanning electron microscope, showed smooth granule surface with circular and polyhedral shapes for large and small granules, respectively. molecular size distribution, intrinsic viscosity and degree of cristallinity of starches from both varieties were similar; however, amylose content was higher for the starch from the ac variety. higher values of viscosity, swelling power and gelatinization temperatures were observed for the starch from the asa variety, which could be related to the lower amylose content and the higher proportion of large granules exhibited by this starch.
