Manipulus Rubiacearum - V. A revision of the genus Capirona.

The taxonomic histort of the genus Capirona is presented. Complete synonymies, descriptions, common names, distributions and discussions are given for Capirona and its two species C. descorticans and C. leiophloea. The generic distribution is the Amazon valley and eastern Guianas and coincides with that of the genus Hevea. C. descorticans is know from the western and southeastern Amazon valley; C. leiophloea is reported from the eastern Guianas and the northeastern Amazon valley. The zone of contact between the two species is along the southern edge oh the Amazon River and the lower drainage of the Rio Tapajoz in Pará, Brazil.

Revision of the genus Macrostomus Wiedemann (Diptera: Empididae: Empidinae): II. The pictipennis species-group

All species of Macrostomus Wiedemann allied with Macrostomus pictipennis (Bezzi), are treated in the pictipennis species-group. Three currently recognized species and four new species are included, namely M. cervicicauda Smith, M. cysticercus Smith, M. manauara, sp. nov. from Brazil (Amazonas and Pará states), M. pacaraima, sp. nov. from Brazil (Roraima, Amazonas and Pará states), M. pictipennis (Bezzi), M. smithi, sp. nov. from Guyana and Brazil (Roraima State) and M. utinga, sp. nov. from Brazil (Pará State). All primary types were examined and a key to species is presented.

Assessment of functional capacity through oxygen consumption in patients with asymptomatic probable heart disease

PURPOSE: To compare peak exercise oxygen consumption (VO2peak) of healthy individuals with asymptomatic individuals with probable heart disease. METHODS: Ninety-eight men were evaluated. They were divided into two groups: 1) 39 healthy individuals (group N) with an age range of 50±4.6 years; and 2) 59 asymptomatic individuals with signs of atherosclerotic and/or hypertensive heart disease (group C) with an age range of 51.9±10.4 years. In regard to age, height, body surface area, percentage of fat, lean body mass, and daily physical activity, both groups were statistically similar. Environmental conditions during the ergometric test were also controlled. RESULTS: Maximal aerobic power (watts), VO2peak, maximal heart rate, and maximal pulmonary ventilation were lower in group C (p<0.01) than in group N; weight, however, was lower in group N (p=0.031) than in group C. Differences in the respiratory gas exchange index, heart rate at rest, and the maximal double product of the two groups were not statistically significant. CONCLUSION: Signs of probable heart disease, even though asymptomatic, may reduce the functional capacity, perhaps due to the lower maximal cardiac output and/or muscle metabolic changes.

Analysis of the risk factors for allograft vasculopathy in asymptomatic patients after cardiac transplantation

OBJECTIVE: To study the influence of immune and nonimmune risk factors on the development of allograft vasculopathy after cardiac transplantation. METHODS: We studied 39 patients with a mean age of 46±12 years. The following variables were analyzed: weight (kg), body mass index (kg/m²), donor's age and sex, rejection episodes in the first and second years after transplantation, systolic and diastolic blood pressures (mmHg), total cholesterol and fractions (mg/dL), triglycerides (mg/dL), diabetes, and cytomegalovirus infection. The presence of allograft vasculopathy was established through coronary angiography. RESULTS: Allograft vasculopathy was observed in 15 (38%) patients. No statistically significant difference was observed between the two groups in regard to hypertension, cytomegalovirus infection, diabetes, donor's sex and age, rejection episodes in the first and second years after transplantation, and cholesterol levels. We observed a tendency toward higher levels of triglycerides in the group with disease. Univariate and multivariate analyses showed statistically significant differences between the two groups when we analyzed the body mass index (24.53±4.3 versus 28.11±4.6; p=0.019). CONCLUSION: Body mass index was an important marker of allograft vasculopathy in the population studied.

Modelo de Gestion Intersectorial para la formalización de villas, a partir de la revisión de normativa urbana, marco jurídico-político, y la innovación tecnológica de los recursos. Intersectorial management model for the formality of the illegal growth settles beginning from the revision of the urban norm, political - juridical, and the technological innovation of the resources.

El Proyecto que se presenta en esta convocatoria está relacionado con el diseño y desarrollo de procesos de gestión intersectorial para la reconversión formal del hábitat en asentamientos de crecimiento espontáneo e ilegal a partir de la la revisión de marcos legales y normativos respecto del derecho al uso de suelo urbano y la seguridad jurídica en la tenencia (regulación dominial) bajo un enfoque sustentable de los Derechos Humanos (DDHH) como así también a partir de la innovación tecnológica de los recursos para el mejoramiento habitacional en el marco de los aportes relacionados con la Responsabilidad Social Empresarial (RSE) .La originalidad, en este caso, se basa en la exploración de nuevos procesos de gestión mixta en los que intervienen diversos actores: ESTADO, SOCIEDAD, EMPRESA y COMUNIDAD CIENTIFICA, configurando un circuito intersectorial de gestión, capacitación y producción de hábitat que respondan al fortalecimiento del desarrollo comunitario, entendido como desarrollo económico con inclusión social y urbana.Los objetivos están relacionados con el fortalecimiento de la producción integral del hábitat social procurando el desarrollo genuino de las comunidades a partir de la expansión de sus capacidades y sus derechos.El presente proyecto de investigación explorará la producción de hábitat y de ciudad informal procurando reconvertirla hacia un modelo de gestión sustentable (normativo y tecnológico), basado en la necesidad de producir ciudadanía digna a partir de la construcción formal de hábitat.La propuesta del proyecto supone la participación intersectorial en la planificación formal y en la toma de decisiones para una inclusión social y económica, en el marco de un modelo de desarrollo de génesis inclusor, constituyéndose en un avance de conocimientos del propio campo disciplinar (hábitat) como así también de otros campos afines a los mismos (jurídico- social - económico- productivo- político ).

p.Q192R SNP of PON1 seems not to be Associated with Carotid Atherosclerosis Risk Factors in an Asymptomatic and Normolipidemic Brazilian Population Sample

Background:Evidences suggest that paraoxonase 1 (PON1) confers important antioxidant and anti-inflammatory properties when associated with high-density lipoprotein (HDL).Objective:To investigate the relationships between p.Q192R SNP ofPON1, biochemical parameters and carotid atherosclerosis in an asymptomatic, normolipidemic Brazilian population sample.Methods:We studied 584 volunteers (females n = 326, males n = 258; 19-75 years of age). Total genomic DNA was extracted and SNP was detected in the TaqMan® SNP OpenArray® genotyping platform (Applied Biosystems, Foster City, CA). Plasma lipoproteins and apolipoproteins were determined and PON1 activity was measured using paraoxon as a substrate. High-resolution β-mode ultrasonography was used to measure cIMT and the presence of carotid atherosclerotic plaques in a subgroup of individuals (n = 317).Results:The presence of p.192Q was associated with a significant increase in PON1 activity (RR = 12.30 (11.38); RQ = 46.96 (22.35); QQ = 85.35 (24.83) μmol/min; p < 0.0001), HDL-C (RR= 45 (37); RQ = 62 (39); QQ = 69 (29) mg/dL; p < 0.001) and apo A-I (RR = 140.76 ± 36.39; RQ = 147.62 ± 36.92; QQ = 147.49 ± 36.65 mg/dL; p = 0.019). Stepwise regression analysis revealed that heterozygous and p.192Q carriers influenced by 58% PON1 activity towards paraoxon. The univariate linear regression analysis demonstrated that p.Q192R SNP was not associated with mean cIMT; as a result, in the multiple regression analysis, no variables were selected with 5% significance. In logistic regression analysis, the studied parameters were not associated with the presence of carotid plaques.Conclusion:In low-risk individuals, the presence of the p.192Q variant ofPON1 is associated with a beneficial plasma lipid profile but not with carotid atherosclerosis.
