1. 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

2. Bioactive peptides from beef products fermented by acid whey – in vitro and in silico study
ABSTRACT: This research investigated the potential of beef products with acid whey to release bioactive peptides and thereby emphasize their health-promoting potential. Peptide sequences were isolated and identified by liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS). Firstly, the antihealth properties (toxicity, allergenicity) of

4. Diagnostic methods in sepsis: the need of speed
OBJECTIVE: Sepsis is a common condition encountered in hospital environments. There is no effective treatment for sepsis, and it remains an important cause of death at intensive care units. This study aimed to discuss some methods that are available in clinics, and tests that have been recently developed for the diagnosis of sepsis. METHODS: A systematic rev

5. Estudo das atividades das cabenegrinas A-I e A-II frente aos efeitos hematolÃgicos e histolÃgicos induzidos pelo veneno total e fraÃÃes da serpente Bothrops neuwiedi em camundongos Swiss. / Study of the activities of cabenegrinas A-I and A-II compared to the histological and hematological effects induced by the venom and fractions of the snake Bothrops neuwiedi in Swiss mice.
The venom of the Bothrops neuwiedi provokes an action mainly of the hemorrhagic, proteolytic and coagulant type. When inoculated, the venom cause primarily a local action, and secondarily a systemic action. The systemic effects of poisoning include changes in various systems such as hematological, cardiovascular, liver, urinary, respiratory, immune, digestiv

6. Desenvolvimento e avaliação imunológica de Nanotubos de Carbono funcionalizados com a proteína de envelope de Dengue virus 3
In terms of epidemiologic impact, Dengue (DENV) infections represent the most important infectious disease in Brazil. Consequently, the development of an efficient vaccine is considered a high priority. Due to this fact, many studies are being developed towards this goal, but no vaccine is currently available to the population. Carbon Nanotubes (CNT) have be

7. Transcriptional networks reconstruction: identification of genes involved on cattle response to tick Rhipicephalus (Boophilus) microplus infestation.
In tropical countries, losses caused by tick infestation in cattle lead to a great impact on animal production systems. Weight and feed conversion reduction, together with diseases transmitted by the parasite are some of the problems that lead to economic losses of billion dollars a year. In a general way, Bos taurus indicus cattle are less susceptible to in

8. Expression and purification of the immunogenically active fragment B of the Park Williams 8 Corynebacterium diphtheriae strain toxin
The construction of a hexahistidine-tagged version of the B fragment of diphtheria toxin (DTB) represents an important step in the study of the biological properties of DTB because it will permit the production of pure recombinant DTB (rDTB) in less time and with higher yields than currently available. In the present study, the genomic DNA of the Corynebacte

9. Interleukin-6 promoter polymorphisms (-174 G/C) in Malaysian patients with systemic lupus erythematosus
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that involves the inflammation of various organs upon deposition of immune complexes and is characterized by uncontrolled B cell hyperactivity. Despite intensive research on the etiology of the disease, the exact cause of the onset of SLE is unknown. The pathogenesis of the disease has been p

10. Estudo da modulação de funções efetoras de neutrófilos humanos por derivados cumarínicos: avaliação do efeito biológico sobre a produção de espécies reativas de oxigênio e a desgranulação / Study of modulation of human neutrophil effector functions by coumarin derivatives: evaluation of biological effect on reactive oxygen species production and degranulation
Neutrophils are phagocytic cells from the innate immune system with highly developed mechanisms for intracellular digestion of pathogens, immune complexes and cell debris, which are mainly mediated by reactive oxygen species (EROs) and proteolytic enzymes. However, massive neutrophil activation lead to release of large amounts of enzymes and EROs to the extr

11. Investigation of a framework based on artificial immune system applied to the pattern recognition / InvestigaÃÃo de uma arquitetura baseada em sistemas imunolÃgicos artificiais aplicada ao reconhecimento de dÃgitos manuscritos
The discovery of new functionalities through the study of human physiology has contributed toward the evolution of Artificial Immune Systems. The present work investigates a new architecture through observations of natural immunological behavior. New functionalities observed in the biological environment were studied for the modeling of this immunological ap
