Association between ear creases and peripheral arterial disease

INTRODUCTION: Peripheral arterial disease is a severe manifestation of atherosclerosis that can lead to critical ischemia of the lower limbs and is also associated with high cardiovascular risk. Diagonal lobular and anterior tragal ear creases have been associated with coronary artery disease, but they have not yet been investigated in patients with peripheral arterial disease.OBJECTIVES: To evaluate the prevalence of ear creases among patients with peripheral arterial disease of the lower limbs, compared with patients without documented atherosclerotic disease.METHODS: Cross-sectional study including 60 male patients with peripheral arterial disease of the lower limbs and 60 dermatologic outpatients matched for age and gender. The associations were adjusted for other risk factors by conditional logistic regression.RESULTS: The prevalence of diagonal and anterior tragal ear creases was higher among cases (73% vs. 25% and 80% vs. 43%, respectively) than controls; these associations remained significant even when adjusting for other known risk factors of atherosclerosis (odds ratio = 8.1 and 4.1, respectively).CONCLUSIONS: Ear creases are independently associated with peripheral arterial disease and may be an external marker for risk identification.

Concentração de enzimas amilolíticas na hidrólise do amido de gengibre

Uma possibilidade de incremento na cadeia produtiva do gengibre seria o uso de rizomas desclassificados para comercialização in natura, ou mesmo o resíduo da extração de óleos, como matérias-primas para a obtenção de bebidas destiladas. O amido não é diretamente fermentável, necessitando de uma hidrólise prévia de suas cadeias para a obtenção de glicose. Neste trabalho, objetivou-se avaliar o efeito das concentrações de amilases sobre o perfil de açúcares e rendimento no processo de hidrólise-sacarificação de gengibre. O processo seguiu o delineamento central composto rotacional para dois fatores, totalizando 11 tratamentos. Os resultados obtidos mostram o efeito das concentrações da α-amilase (Termamyl 2X) e da amiloglucosidase (AMG 300L) sobre o teor de glicose do hidrolisado e efeito da concentração de amiloglucosidase sobre o teor de dextrina. Os maiores rendimentos de hidrólise da suspensão de gengibre foram obtidos nas condições de elevada concentração de -amilase e amiloglucosidase.

Theoretical motivation for studying superstrings

I try to explain why many high-energy theoretical physicists are studying superstrings.

Avaliação de híbridos de pepino tipo japonês sob ambiente protegido em duas épocas de cultivo

Foram avaliados 12 híbridos de pepino do tipo japonês em cultivo de verão (duas repetições, 7 plantas/parcela) e 14 em cultivo de outono-inverno (quatro repetições, 5 plantas/parcela), em um delineamento em blocos ao acaso, com o objetivo de avaliar o comportamento dos mesmos sob cultivo protegido nas condições de São Manuel (SP). Somente o híbrido Rensei caracterizou-se por ser ginóico, e os demais (AF-1327, AF-1328, AF-1329, BU-92, Hokuho, Hokushin, Hyuma, KH-705, Natsusuzumi, Nikkey, Summer Green, Top Green, Tsuyataro e Yoshinari) foram monóicos, embora todos partenocárpicos. Os híbridos mais produtivos no cultivo de verão foram o Tsuyataro (25,4 frutos/planta) e o Rensei (25,3 frutos/planta). No cultivo de outono-inverno foram o Nikkey (26,8 frutos comerciais/planta) e Top Green (23,4 frutos comerciais/planta) e os menos produtivos foram o Rensei (16,1 frutos comerciais/planta) e o AF-1328 (17,6 frutos comerciais/planta). em média, obteve-se maior produção no cultivo de outono-inverno.

Fungal pyogranulomatous encephalitis in a dog with leishmaniosis

É relatado um caso de encefalite piogranulomatosa em um cão fêmea de um ano de idade, da raça Fila Brasileiro. Ao exame macroscópico do cérebro, evidenciou-se área amolecida e hemorrágica no córtex frontal direito e na superfície de corte do hemisfério esquerdo, afetando a substância branca e áreas corticais profundas. O diagnóstico de encefalite piogranulomatosa micótica multifocal foi realizado através de exame histopatológico, que mostrou a presença de macrófagos, células gigantes, focos de hemorragia e hifas septadas de coloração marrom, com distribuição difusa e invadindo a luz de vasos. A identificação de formas amastigotas no imprint de linfonodo poplíteo confirmou o diagnóstico de leishmaniose. A infecção micótica no cérebro deste cão foi relacionada com a ocorrência concomitante de leishmaniose, uma doença imunossupressora.

A MODEL OF THE DEUTERON BASED ON A BREIT TYPE EQUATION

A relativistic treatment of the deuteron and its observables based on a two-body Dirac (Breit) equation, with phenomenological interactions, associated to one-boson exchanges with cutoff masses, is presented. The 16-component wave function for the deuteron (J(pi) = 1+) solution contains four independent radial functions which obey a system of four coupled differential equations of first order. This radial system is numerically integrated, from infinity to the origin, by fixing the value of the deuteron binding energy and using appropriate boundary conditions at infinity. Specific examples of mixtures containing scalar, pseudoscalar and vector like terms are discussed in some detail and several observables of the deuteron are calculated. Our treatment differs from more conventional ones in that nonrelativistic reductions of the order c-2 are not used.

Revolutionaries and bandits: the Villista trajectory in the Mexican Revolution

In the last decades of the 1901 century the Mexican society went through a period of political and economical stability, and relative social tranquility. on contrast, during the revolutionary context various armed movements promoted the disruption of this status quo. In this article, by the analysis of several testimonies, I intend to show some aspects regarding criminality and violence phenomena, during the 1910 and 1920 years on the Northern Mexico.

N = 2 superconformal description of superstring in Ramond-Ramond plane wave backgrounds

Using the U(4) formalism developed ten years ago, the worldsheet action for the superstring in Ramond-Ramond plane wave backgrounds is expressed in a manifestly N = (2,2) superconformally invariant manner. This simplifies the construction of consistent Ramond-Ramond plane wave backgrounds and eliminates the problems associated with light-cone interaction point operators. © SISSA/ISAS 2002.

Avaliação de diferentes inclinações e exposições de telhado em três tipos de cobertura em modelos reduzidos de instalações zootécnicas

The present study was developed in Departamentos de Engenharia Rural e Morfologia e Fisiologia Animal da FCAV/Unesp. The objective of evaluating different roof slopes and exposure in three types of coverage in models of animal installations. Project 48 built reduced models of wood were used with dimensions of 1,00 x 1,00 x 0,50 meters. The covering was one water, lateral and wood floor, disposed in the exhibitions North-south, being 24 prototypes in the north exhibition and 24 in the south. Were used in the covering roofs of ceramic type, galvanized steel and asbestos. The slopes varied of 20, 30, 40 and 50% for ceramic tile and 10, 30, 40 and 50% for the others and with two repetitions for slope. Inside the reduced models temperature readings were accomplished, of hour in hour during one year, for the system of acquisition of Data Logger Campbell Scientific-Ínc and externally the temperature of the air, incident radiation global solar, precipitation, speed and relative humidity of the air were measured. The results obtained during the experimental period of one year were appraised statistically for the statistical package SAS in the factorial outline, where three factors were considered: tile type, slope degree and exposure. The obtained averages were compared through the test of Tukey to 5% of probability. After analyzing the data we found that with increasing slope, there was a decrease in inside temperature in the cover prototypes, therefore, using steeper slopes with 50% of tipping ceramics and asbestos, with greater coverage on display South, we have lower temperatures in poultry houses in the geographic coordinates of the city of Jaboticabal.
