To evaluate the antifungal effect of dobutamine against
as well as its synergism with azoles and its action on biofilm.
The M27-A3 protocol and flow cytometry were used for elucidation of the ...possible mechanism of action.
The tested isolates presented MICs ranging from 2 to 32 μg/ml for dobutamine, with fungistatic effect. A total of 82% of the strains showed synergism with fluconazole, with 90% showing synergism with itraconazole. The effect on biofilm formation was nonsignificant. Cytometry tests showed that dobutamine induced mitochondrial depolarization.
Dobutamine has an antifungal effect on strains of
and synergistic activity with azoles. This effect is probably mediated by increased oxidative damage to the membrane.

Abstract
Vergil interweaves the varying meanings of
amor
, from not only a positive force, to aggressive desires and to all its varied aspects, making it both harsh, deceptive and cruel, and ...conversely something very special reflecting things most cherished and respected.
Neste artigo apresentamos uma interpretação ao discurso de Fedro do Banquete platônico, um dos menos trabalhados pela tradição interpretativa. Analisamos inserção das três personagens: Alceste, Orfeu ...e Aquiles, na estrutura do discurso. Alceste uma mulher que morre para que o marido Admeto continue vivo, Orfeu que não tendo coragem de morrer por Eurídice invade o Hades usando artifícios e Aquiles que segue Pátroclo na morte. Compreendemos então o olhar favorável reservado a Aquiles no discurso. Nossa interpretação explora questões relativas à pederastia e marca no texto a diferença entre referências específicas a essa instituição e simples referências a amantes e amados, essas últimas mais amplas. Amplas ao ponto de inserir, como amante, numa fala marcada por referências a contextos em que figuram exclusivamente homens, a personagem Alceste. Fedro apresenta a variável do olhar do parceiro um elemento intensificador do repúdio às coisas repugnantes e da ambição pelas coisas belas, mecanismo característico da relação erótica e fundamental para sua coesão. O ápice da manifestação de Eros seria morrer pelo outro. A posição de eromenos na relação pederástica e o fato de ter morrido quando Pátroclo já estava morto são elementos que diferenciam a narrativa de Aquiles da de Alceste. Apesar de terem morrido por quem amavam, Aquiles, um menino, o fez sem que estivesse sob o olhar do outro. Nossa leitura permite, ao verificar meandros da fala e Fedro, compreender o extraordinário benefício concedido pelos deuses ao eromenos Aquiles neste que é o primeiro dos discursos do Banquete.
Near-Earth Asteroids (NEAs) are excellent laboratories for processes that affect the surfaces of airless bodies. Most NEAs were not expected to contain OH/H2O on their surfaces because they are ...primarily S-complex objects and sourced from the inner Main Belt, which is interior of the frost line, and their surface temperatures are high enough to remove these volatiles. However, a 3-μm feature typically indicative of OH/H2O was identified on other seemingly dry bodies in the inner Solar System, such as the Moon and Vesta, and more recently on the NEAs (433) Eros, (1036) Ganymed, and (3122) Florence. The most likely sources for OH/H2O on these bodies include carbonaceous chondrite impacts or interactions with protons implanted by solar wind. We investigated the causes of band depth and shape variations on NEAs by comparing new observations of Eros and Ganymed to those previously published and conducting a rotationally-resolved spectral study on Florence. All spectra discussed were collected by SpeX on NASA's IRTF using the LXD_short (1.67–4.2 μm) mode to characterize the 3-μm region. Some observations also used the prism (0.7–2.52 μm) mode to characterize asteroid spectral type and investigate silicate composition dependencies. All three asteroids possess exogenously sourced OH/H2O and have spectra that show potential spatially correlated variations in band depth or shape. Eros' band is slightly wider at the poles than at lower sub-observer latitudes, possibly due to its high obliquity, which ensures that each polar region is oriented toward the Sun over a significant part of its orbit. Ganymed's trends in hydration band depth with sub-solar longitude and band I center suggest a carbonaceous or cometary impactor that struck the surface around 0° relative longitude, excavating a relatively magnesium- and olivine-enriched layer. Florence's total hydrogen concentration remains stable across the surface even as the OH-to-H2O ratio changes as the asteroid rotates. These three examples suggest that non-native OH/H2O on other bodies will likely also be spatially dependent, regardless of delivery mechanism.
•Near-Earth asteroids (NEAs) (433) Eros, (1036) Ganymed, and (3122) Florence exhibit signs or potential signs of hydration.•Numerous observations of Eros and Ganymed show the near infrared (NIR) hydration band varies in depth and shape.•Rotational study of NIR hydration band on Florence also shows depth and shape variations.•The hydrated material is likely exogeneous, from solar wind hydrogen implantation and/or carbonaceous/cometary impacts.•Hydration band depth and shape variations on all three NEAs are potentially spatially correlated.

The conceptualization of “love” in Saint Augustine’s thought is addressed. This paper aims to understand how the concept of love structures his doctrine and how it is presented. This study is, for ...its nature itself, a documental search. Three analytical sources are used: First, Saints Augustine’s writings; second, documents corresponding to Greek ideas he used in his thought; and third, contemporary literature addressing his thought. It is organized into six sections: an introduction; next, the faces of love such as Eros (Ἔρως), philia (φιλία), and agape (ἀγάπη); and then, the objects of love and individual and collective dimensions are analyzed. It therefore follows that love is the main resource Saint Augustine used to understand human problems and relationships.
Se aborda la conceptualización de “amor” en el pensamiento de san Agustín. El objetivo de este artículo es comprender cómo el concepto del amor estructura su doctrina y, de qué manera la presenta. Esta investigación es por su naturaleza una indagación de corte documental; se emplean tres fuentes de análisis, en primer lugar, los escritos de san Agustín; en segundo lugar, documentos correspondientes a las ideas griegas del que fueron empleadas en su pensamiento; y, en tercer lugar, literatura contemporánea que abordó el pensamiento de San Agustín. Este informe se expresa en seis apartados: uno introductorio, luego se aborda las caras del amor como Eros (Ἔρως), filía (φιλία) y ágape (ἀγάπη); a continuación, se analiza los objetos de amor y las dimensiones (individual y colectivo). Se concluye que el amor es el recurso principal que usa San Agustín para comprender las problemáticas y relaciones humanas.
In order to understand the geological evolution of asteroids Eros, Itokawa and Ryugu and their collisional history, previous studies investigated boulder size distributions on their surfaces. ...However, quantitative comparison of these size distributions is hampered by numerous differences between these studies regarding the definition of a boulder's size, measuring technique and the fitting method to determine the power-index of the boulder size distributions. We provide a consistent and coherent model of boulder size distributions by remeasuring the boulders on the entire surfaces of Eros and Itokawa using the Small Body Mapping Tool (SBMT) and combining our observations with the Ryugu data of Michikami et al. (2019). We derived power-indices of the boulder size distributions of −3.25 ± 0.14 for Eros, −3.05 ± 0.14 for Itokawa and −2.65 ± 0.05 for Ryugu. The asteroid with the highest number density of boulders ≥ 5 m turns out to be Ryugu, not Itokawa, as suggested by an earlier study. We show that the appearance of the boulders tends towards more elongated shapes as the size of an asteroid decreases, which can be explained by differences in asteroid gravity and boulder friction angles. Our quantitative observational results indicate that boulder migration preferentially affects smaller boulders, and tends to occur on larger asteroids.
•First comparative survey free from observer bias of boulders on Eros, Itokawa and Ryugu.•Boulders appear to be more elongated as the size of an asteroid decreases.•Boulder migration preferentially affects smaller boulders and larger asteroids.
The article considers a significant aspect of Strada per Roma, namely the narcissistic personality of the main protagonist, the young Guido Corsalini, and the sensual valence of Paolo Volponi's early ...poetic production written at the same time of this novel. To this end, the essay traces, also in the light of analytical doctrines on the subject, but not only, Guido's inner journey, focusing on those episodes that highlight an Ego of the character that has remained emotionally stuck at an infantile age. Indeed, it will be the experience of intimacy with Barnaba, the separation from his childhood friend Ettore, that will mentally project Guido into a different, more adult and conscious mental atmosphere, on the streets of Roma.
A partir de la revisión de la antología El canon abierto. Última poesía en español el presente artículo plantea que una importante parte de la poesía en lengua española circunda el tema de la ...construcción de la imagen. Esto lo hace a partir de la melancolía y de la estética barroca que fungen como dos características canónica de la cultura iberoamericana. En el trabajo se observa que pese a las diferentes corrientes estéticas de dicha poesía existe una tendencia natural hacia la recreación de imágenes inspiradas o generadas por el estado melancólico.
•Fast Optical Imaging allows to unveil spatio-temporal dynamics of consciousness•When entering consciousness, visual stimuli elicit a sustained activation of LOC•LOC activity predicts subsequent ...activity in visual and motor areas•Activity in LOC occurs in the temporal window of VAN•LOC could represent a reliable neural correlate of phenomenal consciousness
The study of the neural substrates that serve conscious vision is one of the unsolved questions of cognitive neuroscience. So far, consciousness literature has endeavoured to disentangle which brain areas and in what order are involved in giving rise to visual awareness, but the problem of consciousness still remains unsolved. Availing of two different but complementary sources of data (i.e., Fast Optical Imaging and EEG), we sought to unravel the neural dynamics responsible for the emergence of a conscious visual experience. Our results revealed that conscious vision is characterized by a significant increase of activation in extra-striate visual areas, specifically in the Lateral Occipital Complex (LOC), and that, more interestingly, such activity occurred in the temporal window of the ERP component commonly thought to represent the electrophysiological signature of visual awareness, i.e., the Visual Awareness Negativity (VAN). Furthermore, Granger causality analysis, performed to further investigate the flow of activity occurring in the investigated areas, unveiled that neural processes relating to conscious perception mainly originated in LOC and subsequently spread towards visual and motor areas. In general, the results of the present study seem to advocate for an early contribution of LOC in conscious vision, thus suggesting that it could represent a reliable neural correlate of visual awareness. Conversely, striate visual areas, showing awareness-related activity only in later stages of stimulus processing, could be part of the cascade of neural events following awareness emergence.
