Determinação da estrutura e estudo da função da metalotioneína de Synechococcus com ferramentas da bioinformática.

Este trabalho abordou a análise estrutural das MTs a fim de se modelar esta proteína e com isso compreender melhor o funcionamento da mesma. O conhecimento da cianobactéria e uma completa análise da MT poderia ser muito útil em um estudo de utilização desta na técnica da biorremediação para remover metais pesados do solo e da água decorrentes das praticas agrícolas atuais.

GABAA receptor chloride channels are involved in the neuroprotective role of GABA following oxygen and glucose deprivation in the rat cerebral cortex but not in the hippocampus.

Assays on "ex vivo" sections of rat hippocampus and rat cerebral cortex, subjected to oxygen and glucose deprivation (OGD) and a three-hour reperfusion-like (RL) recovery, were performed in the presence of either GABA or the GABA(A) receptor binding site antagonist, bicuculline. Lactate dehydrogenase (LDH) and propidium iodide were used to quantify cell mortality. We also measured, using real-time quantitative polymerase chain reaction (qPCR), the early transcriptional response of a number of genes of the glutamatergic and GABAergic systems. Specifically, glial pre- and post-synaptic glutamatergic transporters (namely GLAST1a, EAAC-1, GLT-1 and VGLUT1), three GABAA receptor subunits (α1, β2 and γ2), and the GABAergic presynaptic marker, glutamic acid decarboxylase (GAD65), were studied. Mortality assays revealed that GABAA receptor chloride channels play an important role in the neuroprotective effect of GABA in the cerebral cortex, but have a much smaller effect in the hippocampus. We also found that GABA reverses the OGD-dependent decrease in GABA(A) receptor transcript levels, as well as mRNA levels of the membrane and vesicular glutamate transporter genes. Based on the markers used, we conclude that OGD results in differential responses in the GABAergic presynaptic and postsynaptic systems.

La trayectoria deportiva hacia el rendimiento en los deportes colectivos

¿Cómo es la trayectoria seguida por un jugador de fútbol desde que empieza a dar sus primeros pasos con el balón hasta que alcanza el rendimiento que le permita competir en la liga profesional de fútbol?, ¿cómo ocurre en el baloncesto o en el balonmano? Son muchos los factores que influirán sin duda alguna en dicho proceso. Entre dichos factores, en los últimos años, se ha considerado de forma detenida la influencia de la “practica deliberada” en el desarrollo del deportista. Sin embargo, son varios los autores y estudios que explican que no solo influye dicha practica, sino que también es muy importante la influencia del “juego deliberado”, bien en el mismo deporte, bien en otras especialidades deportivas, y que ambos tipos de practica son compatibles formando un continuum en el tiempo. Este artículo tiene como objetivo presentar el estado de la arte en torno a este debate, en el ámbito de los deportes colectivos, analizando si en los deportes colectivos los deportistas se especializan al principio en un solo deporte o bien si practican varias disciplinas deportivas para finalmente dedicarse exclusivamente a un deporte. Los resultados apuntan a que no existe un único camino en el desarrollo del deportista, y que razones de carácter social y cultural son las que realmente condicionan dicho proceso

Changes in the mechanical characteristics of the knee musculature in professional female volleyball players

The technical efficiency in volleyball is closely related to the ability to perform displacements or jump (1). Therefore, it is necessary that precise, individualized, and localized evaluation of the muscles frequently involved in volleyball practice be studied (2,3). The aim of this study was to analyze the neuromuscular changes of the knee musculature in professional volleyball players using Tensiomyography (TMG) and jump tests.

'Adipaging': Aging and obesity share biological hallmarks related to a dysfunctional adipose tissue

The increasing aging of our societies is accompanied by a pandemic of obesity and related cardiometabolic disorders. Progressive dysfunction of the white adipose tissue is increasingly recognized as an important hallmark of the aging process which in turn contributes to metabolic alterations, multi-organ damage, and a systemic pro-inflammatory state ('inflammaging'). On the other hand, obesity, the paradigm of adipose tissue dysfunction, shares numerous biological similarities with the normal aging process such as chronic inflammation and multi-system alterations. Accordingly, understanding the interplay between accelerated aging related to obesity and adipose tissue dysfunction is critical to gain insight into the aging process in general as well as into the pathophysiology of obesity and other related conditions. Here we postulate the concept of 'adipaging' to illustrate the common links between aging and obesity and the fact that, to a great extent, obese adults are prematurely aged individuals.

Biological rationale for regular physical exercise as an effective intervention for the prevention and treatment of depressive disorders

Depression is a major medical and social problem. Here we review current body of knowledge on the benefits of exercise as an effective strategy for both the prevention and treatment of this condition. We also analyze the biological pathways involved in such potential benefits, which include changes in neurotrophic factors, oxidative stress and inflammation, telomere length, brain volume and microvessels, neurotransmitters or hormones. We also identify major caveats in this field of research: further studies are needed to identify which are the most appropriate types of exercise interventions (intensity, duration, or frequency) to treat and prevent depression.

The extradomain a of fibronectin enhances the efficacy of lipopolysaccharide defective Salmonella bacterins as vaccines in mice

The Extradomain A from fibronectin (EDA) has an immunomodulatory role as fusion protein with viral and tumor antigens, but its effect when administered with bacteria has not been assessed. Here, we investigated the adjuvant effect of EDA in mice immunizations against Salmonella enterica subspecies enterica serovar Enteritidis (Salmonella Enteritidis). Since lipopolysaccharide (LPS) is a major virulence factor and the LPS O-polysaccharide (O-PS) is the immunodominant antigen in serological diagnostic tests, Salmonella mutants lacking O-PS (rough mutants) represent an interesting approach for developing new vaccines and diagnostic tests to differentiate infected and vaccinated animals (DIVA tests). Here, antigenic preparations (hot-saline extracts and formalin-inactivated bacterins) from two Salmonella Enteritidis rough mutants, carrying either intact (SE Delta waaL) or deep-defective (SE Delta gal) LPS-Core, were used in combination with EDA. Biotinylated bacterins, in particular SE Delta waaL bacterin, decorated with EDAvidin (EDA and streptavidin fusion protein) improved the protection conferred by hot-saline or bacterins alone and prevented significantly the virulent infection at least to the levels of live attenuated rough mutants. These findings demonstrate the adjuvant effect of EDAvidin when administered with biotinylated bacterins from Salmonella Enteritidis lacking O-PS and the usefulness of BEDA-SE Delta waaL as non-live vaccine in the mouse model.
