Caracterização do ritmo circadiano de atividade e repouso em saguis idosos (Callithrix Jacchus)

Advanced age may become a limiting factor for the maintenance of rhythms in organisms, reducing the capacity of generation and synchronization of biological rhythms. In this study, the influence of aging on the expression of endogenous periodicity and synchronization (photic and social) of the circadian activity rhythm (CAR) was evaluated in a diurnal primate, the marmoset (Callithrix jacchus). This study had two approaches: one with longitudinal design, performed with a male marmoset in two different phases: adult (three years) and older (9 y.o.) (study 1) and the second, a transversal approach, with 6 old (♂: 9.7 ± 2.0 y.o.) and 11 adults animals (♂: 4.2 ± 0.8 y.o.) (study 2). The evaluation of the photic synchronization involved two conditions in LD (natural and artificial illuminations). In study 1, the animal was subjected to the following stages: LD (12:12 ~ 350: ~ 2 lx), LL (~ 350 lx) and LD resynchronization. In the second study, the animals were initially evaluated in natural LD, and then the same sequence stages of study 1. During the LL stage in study 2, the vocalizations of conspecifics kept in natural LD on the outside of the colony were considered temporal cue to the social synchronization. The record of the activity was performed automatically at intervals of five minutes through infrared sensor and actimeters, in studies 1 and 2, respectively. In general, the aged showed a more fragmented activity pattern (> IV < H and > PSD, ANOVA, p < 0.05), lower levels of activity (ANOVA, p < 0.05) and shorter duration of active phase (ANOVA, p < 0.05) in LD conditions, when compared to adults. In natural LD, the aged presented phase delay pronounced for onset and offset of active phase (ANOVA, p < 0.05), while the adults had the active phase more adjusted to light phase. Under artificial LD, there was phase advance and greater adjustment of onset and offset of activity in relation to the LD in the aged (ANOVA, p < 0.05). In LL, there was a positive correlation between age and the endogenous period () in the first 20 days (Spearman correlation, p < 0.05), with prolonged  held in two aged animals. In this condition, most adults showed free-running period of the circadian activity rhythm with  < 24 h for the first 30 days and later on relative coordination mediated by auditory cues. In study 2, the cross-correlation analysis between the activity profiles of the animals in LL with control animals kept under natural LD, found that there was less social synchronization in the aged. With the resubmission to the LD, the resynchronization rate was slower in the aged (t-test; p < 0.05) and in just one aged animal there was a loss of resynchronization capability. According to the data set, it is suggested that the aging in marmosets may be related to: 1) lower amplitude and greater fragmentation of the activity, accompanied to phase delay with extension of period, caused by changes in a photic input, in the generation and behavioral expression of the CAR; 2) lower capacity of the circadian activity rhythm to photic synchronization, that can become more robust in artificial lighting conditions, possibly due to the higher light intensities at the beginning of the active phase due to the abrupt transitions between the light and dark phases; and 3) smaller capacity of non-photic synchronization for auditory cues from conspecifics, possibly due to reducing sensory inputs and responsiveness of the circadian oscillators to auditory cues, what can make the aged marmoset most vulnerable, as these social cues may act as an important supporting factor for the photic synchronization.

Cultivo de microalgas utilizando pentoses como fonte de carbono

As microalgas podem ser consideradas como um dos mais eficientes sistemas biológicos de transformação de energia solar em compostos orgânicos. Quando cultivadas em meios adequados, certas espécies podem duplicar sua biomassa diariamente. Além disso, possuem inúmeras vantagens, como: elevada velocidade de crescimento; potencial para absorver CO2, reduzindo assim a quantidade de emissões deste gás na atmosfera e diminuindo o efeito estufa. O objetivo do trabalho foi estudar o efeito do uso de pentoses no cultivo de Chlorella minutissima, Chlorella vulgaris, Chlorella homosphaera, Dunaliella salina, Spirulina paracas e Synechococcus nidulans, avaliando o perfil cinético do crescimento e a capacidade de produção de carboidratos e proteínas. Para o cultivo das microalgas foram utilizados os meios: Zarrouk, Bristol`S Modificado e DUN. Em todos os meios o componente nitrogenado foi reduzido pela metade e utilizado 1%, 5%, 10%, 20% e 30% de pentoses, com concentrações de xilose e arabinose que representassem as mesmas presentes em caldo hidrolisado do bagaço de cana de açúcar pré-tratado. Os cultivos foram realizados em fotobiorreatores de 2 L, mantidos em estufa a 30 ºC, fotoperíodo de 12h claro/escuro e 2500 Lx, com agitação a uma vazão de 0,75 v.v.m. . O crescimento de biomassa foi monitorado diariamente pela densidade ótica das culturas em espectrofotômetro a 670nm. Foram avaliados parâmetros cinéticos como a concentração máxima de biomassa, produtividade máxima e velocidade específica máxima de crescimento. A determinação do consumo das pentoses foi realizada através da metodologia de Somogy e Nelson, para a determinação de carboidratos foi utilizada uma adaptação do método do ácido 3,5 dinitro salicílico, as proteínas foram quantificadas pelo método de micro-Kjeldahl. Todas as microalgas foram capazes de consumir em no máximo quatro dias as concentrações de pentoses, e logo após esta etapa mixotrófica manter-se em crescimento autotrófico, destacando-se as cepas de Dunaliella salina e Synechococcus nidulans que esgotaram as maiores concentrações utililizadas em dois dias de cultivo. Para as cianobactérias estudadas, Spirulina paracas cultivada com 10% de C5, foi a que obteve os melhores resultados de concentração celular, produtividade e velocidade específica de crescimento máxima, 1,364 g.L-1 , 0,128 g.L-1 .dia-1 e 0,240 dia-1 . Em relação ao efeito na composição da biomassa, Synechococcus nidulans produziu o maior teor de proteínas, 62,9%, nos ensaios com 10% de C5. Já as cepas de Chlorophytas os melhores resultados foram obtidos com o uso de 5% de C5, para os parâmetros cinéticos destacam-se os valores encontrados para Dunaliella salina, onde a maior concentração de biomassa, produtividade e velocidade específica de crescimento foram 1,246 g.L-1 , 0,091 g.L- 1 .dia-1 e 0,379 dia-1 , respectivamente. Chlorella minutissima e Dunaliella salina foram as melhores produtoras de carboidratos, alcançando 58,6%/0,3 g.L-1 e 23,07%/0,29 g.L-1 ,respecivamente. Logo, o uso de pentoses nas microalgas em substituição as fontes tradicionais de carbono, resultou no crescimento das mesmas, o que mostra que estas podem agir como intermediários para a absorção de açúcares de cinco carbonos.

Direct numerical simulation of statistically stationary and homogeneous shear turbulence and its relation to other shear flows

Statistically stationary and homogeneous shear turbulence (SS-HST) is investigated by means of a new direct numerical simulation code, spectral in the two horizontal directions and compact-finite-differences in the direction of the shear. No remeshing is used to impose the shear-periodic boundary condition. The influence of the geometry of the computational box is explored. Since HST has no characteristic outer length scale and tends to fill the computational domain, long-term simulations of HST are “minimal” in the sense of containing on average only a few large-scale structures. It is found that the main limit is the spanwise box width, Lz, which sets the length and velocity scales of the turbulence, and that the two other box dimensions should be sufficiently large (Lx ≳ 2Lz, Ly ≳ Lz) to prevent other directions to be constrained as well. It is also found that very long boxes, Lx ≳ 2Ly, couple with the passing period of the shear-periodic boundary condition, and develop strong unphysical linearized bursts. Within those limits, the flow shows interesting similarities and differences with other shear flows, and in particular with the logarithmic layer of wall-bounded turbulence. They are explored in some detail. They include a self-sustaining process for large-scale streaks and quasi-periodic bursting. The bursting time scale is approximately universal, ∼20S−1, and the availability of two different bursting systems allows the growth of the bursts to be related with some confidence to the shearing of initially isotropic turbulence. It is concluded that SS-HST, conducted within the proper computational parameters, is a very promising system to study shear turbulence in general.

The effect of increased light intensity on the aggressive behavior of the Nile tilapia, Oreochromis niloticus (Teleostei: Cichlidae)

Animals show behavioral and physiological changes that emerge in response to environmental perturbations (i.e., emergency life-history stages). In this study, we investigate the effects of light intensity on aggressive encounters and social stability in groups of adult male Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). The study compared the behavior observed under low (280.75 ± 50.60 lx) and high (1394.14 ± 520.32 lx) light intensities, with 12 replicates for each treatment. Adult fish were isolated in 36-L aquaria for 96 hours, and three males were grouped for 11 days in 140-L aquaria. Agonistic behavior was video-recorded (10 min/day) on the 3rd, 5th, 7th, and 9th day to quantify aggressive interactions and social stability. There was an effect of light intensity and day of observation on the total number of agonistic behaviors performed by the fish group. Besides, increased frequency of aggressive interactions (the sum of the four sessions) by the alpha, beta and gamma fish occurred at the higher light intensity. The dominance ranks of the fish remained unchanged across the observation sessions under both the low and high light intensities. We concluded that enhanced light intensity has a cumulative effect that increases the aggressiveness of the Nile tilapia but that this effect is not sufficiently strong to destabilize the social hierarchy.

Rinitis alérgica tratamiento con montelukast sólo o en combinación con antihistamínicos orales. revisión sistemática

Antecedentes: La rinitis alérgica es una enfermedad secundaria a la exposición a alérgenos con una inflamación de las mucosas nasales mediadas por la Ig-E, tiene síntomas como estornudos, obstrucción nasal, prurito nasal y descarga nasal. Los tratamientos de primera línea son los antihistamínicos orales y Montelukast los cuales se dan como monoterapia, existe la combinación de los dos tratamientos en el mercado, sin embargo se duda de su eficacia combinada para tratar los síntomas nasales. Objetivo: Determinar la eficacia y seguridad del tratamiento combinado de Montelukast con Antihistamínicos orales en el tratamiento de Rinitis Alérgica. Metodología: Se realizó una revisión sistemática de la literatura con metaanálisis de los estudios clínicos que evaluaron la eficacia de los antihistamínicos orales y Montelukast tanto en monoterapia como en terapia combinada. Resultados: De 795 artículos publicados hasta febrero 2016 identificados en las bases de datos electrónicas y literatura gris, se seleccionaron por consenso nueve estudios. Los estudios mostraron una reducción significativa del TNSS de -2,61 (-3.32 a -1,90) de la terapia combinada de Montelukast más antihistamínicos orales en comparación con la monoterapia de cada uno de ellos. Los estudios reportaron que la seguridad de la terapia combinada de Montelukast más antihistamínicos orales no fue diferente a la monoterapia. Conclusiones: La terapia combinada de Montelukast con antihistamínico redujo el puntaje de TNSS en -2,61 (-3.32 a -1,90) por lo que es eficaz y seguro en pacientes con rinitis alérgica.
