1. Association of Anti-β1 and Anti-M2 Antibodies with Autonomic Nervous System Modulation in Patients with Chronic Chagas Cardiomyopathy
Abstract Background: Different immune mechanisms of myocardial damage involved in the pathophysiology of Chagas disease coexist with high titers of autoantibodies induced by T. cruzi . There are few studies in the literature about the adaptive role of anti-β1 and anti-M2 antibodies in chronic Chagas cardiomyopathy (CCC). Objectives: To evaluate the associ

2. Corticotropin-releasing factor receptor signaling and modulation: implications for stress response and resilience
Abstract Introduction In addition to their role in regulation of the hypothalamic-pituitary-adrenal-axis, corticotropin-releasing factor (CRF) and its related peptides, the urocortins, are important mediators of physiological and pathophysiological processes of the central nervous, cardiovascular, gastrointestinal, immune, endocrine, reproductive, and skin

3. Adaptive Modulation and Code Strategy to Reduce Energy Consumption in Elastic Optical Network
Abstract In this paper, the novel Adaptive Modulation and Code (AMC) algorithm aims to reduce energy consumption in elastic optical network is developed. The proposed AMC algorithm adaptively allocates both, the appropriate modulation and the forward error correction (FEC), according to the actual physical distance and the optical signal to noise ratio (OSNR

4. ANALYTICAL COMPARISON OF THE PERFORMANCE OF ADAPTIVE MODULATION AND CODING IN WIRELESS NETWORK UNDER RAYLEIGH FADING
Abstract In this paper, an analytic comparison between adaptive modulation (AdM) and adaptive Forward Error Correction (AdFEC) in wireless network telecommunication systems is performed. Through the Gilbert-Elliott model's, the Packet Error Rate (PER) is calculated and both the throughput and the delay, for different modulations and error correction capacity

5. Adaptive Fuzzy Sliding-Mode Control of Wheel Slide Protection Device for ER24PC Locomotive
Abstract Wheel Slide Protection Devices (WSPD) are employed in railway vehicles to maximize the average of the possible frictional braking force, which is a nonlinear function of the slip ratio of the wheel sets. In this paper, to control the WSPD, a low-order model is presented and un-modeled dynamics are considered as uncertainties. Due to the nonlinear dy

6. Plasticity of neutrophils reveals modulatory capacity
Neutrophils are widely known as proinflammatory cells associated with tissue damage and for their early arrival at sites of infection, where they exert their phagocytic activity, release their granule contents, and subsequently die. However, this view has been challenged by emerging evidence that neutrophils have other activities and are not so short-lived.

7. Modulation of cell proliferation, survival and gene expression by RAGE and TLR signaling in cells of the innate and adaptive immune response: role of p38 MAPK and NF-KB
Objective: The aim of this study was to evaluate a possible synergism between AGE-RAGE and TLR4 signaling and the role of p38 MAPK and NF-kB signaling pathways on the modulation of the expression of inflammatory cytokines and proliferation of cells from the innate and adaptive immune response. Material and Methods: T lymphocyte (JM) and monocyte (U937) ce

8. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

9. Vias efetoras pelas quais a Hsp70 de Mycobacterium tuberculosis inibe a rejeição aguda em um modelo de aloenxerto cutâneo
Transplantation of solid organs has emerged as a viable therapeutic modality for the treatment of a variety of disorders. Rejection of solid organ allografts is the result of a complex range of interactions involving coordination between both the innate and adaptive immune system. Therewith, a major goal of clinical organ transplantation is to induce a donor

10. Influência do Gene pacC na Regulação de Manosiltransferases no Dermatófito Trichophyton rubrum em Função de Variações Nutricionais e pH Ambiente. / Influence of Gene pacC in Mannosiltransferase Regulation of the Dermathophyte Trichophyton rubrum in Function to Changes by pH and Nutrient Sources.
Gene expression regulation is essential for fungi to adapt to environmental adversities, such as changes in the extracellular pH, nutrient starvation, ionic strength, and temperature. The adaptive response to ambient pH is well characterized in model fungi such as Aspergillus nidulans, and involves the signal transduction pathway consisting of the products o

11. Técnicas de equalização de canais de comunicação aplicadas a imagens. / Equalization techniques for communications channels applied to images.
O objetivo da desconvolução autodidata de imagens é reconstruir a imagem original a partir de uma imagem degradada sem usar informação da imagem real ou da função de degradação. O processo de reconstrução é crítico em aplicações em que a imagem original ou suas características estatísticas não são conhecidas. Fazendo um mapeamento da image
