1. Mineral supplementation stimulates the immune system and antioxidant responses of dairy cows and reduces somatic cell counts in milk
ABSTRACT The aim of this study was to evaluate whether the use of subcutaneous mineral supplementation would affect metabolic parameters, immunological response, milk quality and composition of dairy cows in the postpartum period. Twelve pregnant primiparous Holstein cows, were divided into two groups: six animals supplemented with the mineral complex (magne

2. Molecular epidemiology of Streptococcus agalactiae isolated from mastitis in Brazilian dairy herds
Abstract Streptococcus agalactiae is one of the most common pathogens leading to mastitis in dairy herds worldwide; consequently, the pathogen causes major economic losses for affected farmers. In this study, multilocus sequence typing (MLST), genotypic capsular typing by multiplex polymerase chain reaction (PCR), and virulence gene detection were performed

3. Assessment of serum copper, iron and immune complexes in potentially malignant disorders and oral cancer
Abstract Potentially malignant disorders (PMDs) of oral cavity and oral cancer remain a cause of serious concern despite intensive research and development. Diet and immunity have been identified to play a crucial role as modifying factors in these diseases. Our study intended to explore this relationship by estimating and comparing the serum levels of coppe

4. Inflammasomes and dermatology
Abstract: Inflammasomes are intracellular multiprotein complexes that comprise part of the innate immune response. Since their definition, inflammasome disorders have been linked to an increasing number of diseases. Autoinflammatory diseases refer to disorders in which local factors lead to the activation of innate immune cells, causing tissue damage when in

5. Erythema elevatum diutinum and hypothyroidism: coincidence or causal relationship?
AbstractErythema elevatum diutinum is a rare chronic leukocytoclastic vasculitis of unknown etiology. It is believed to be due to deposition of immune complexes in the vessels. Clinically it is manifested as erythematous violaceous papules and nodules, isolated or confluent with hardened consistency, symmetrical, usually located on the extensor surface of th

6. Serum levels of immunoglobulin free light chains in patients with chronic hepatitis C presenting cryoglobulinemia
Hepatitis C virus (HCV) infects B-lymphocytes, provokes cellular dysfunction and causes lymphoproliferative diseases such as cryoglobulinemia and non-Hodgkin's B-cell lymphoma. In the present study, we investigated the serum levels of kappa and lambda free light chains (FLC) of immunoglobulins and the kappa/lambda FLC ratio in Brazilian patients with chronic

7. Cinética de detecção de coproantígenos e de antígenos, anticorpos e imunocomplexos em amostras de soro e de lavado bronco alveolar de ratos imunossuprimidos e experimentalmente infectados por Strongyloides venezuelensis / Kinetic of coproantigen, antigens, antibodies and immune complexes detection in serum and bronchoalveolar lavage fluid samples from rats experimentally infected with Strongyloides venezuelensis
O diagnóstico definitivo da estrongiloidíase normalmente é realizado mediante a detecção de larvas nas fezes; porém a quantidade de parasitos é limitada e a eliminação de larvas é reduzida e irregular. Sendo assim, o desenvolvimento de testes sorológicos confiáveis para o diagnóstico da estrongiloidíase torna-se uma alternativa necessária. O o

8. Epidemiologia da leishmaniose visceral humana em Araguaína (TO) e o diagnóstico sorológico da doença / Epidemiology of human visceral Leishmaniasis in Araguaína (TO) and serological diagnosis of this disease
Human visceral leishmaniasis (HVL) is a severe systemic protozoonosis that has presented changes at the epidemiological behavior, with a growing trend in Brazil. It has been conducted a cross sectional study to assess the context of HVL in the city of Araguaina (TO) from January 2007 to August 2010. Additionally, tests were conducted to compare the diagnosti

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. Biological sensors based on immune response cells applied to the study of anti-allergic activity of natural compounds. / Utilização de sensores biológicos baseados em células de resposta imune no estudo da atividade antialérgica de substâncias naturais.
Anti-allergic activity of extracts and isolated compounds obtained from natural sources was investigated using the mast-cell based biosensor system. Mast cells release beta-hexosaminidase enzyme which is used as a marker of degranulation. Flavonoids (quercetin-Qc and rutin-Rt) and polyphenolic acids (caffeic acid-Cf and dimethoxy cinnamic acid-Dm) were used

11. 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

12. Expressão de recptores do tipo Toll e dectina em monocitos e neutrofilos estimulados pelo Paracoccidioides brasiliensis / Expression of Toll-like receptos and dectin-1 in monocytes and neutrophils stimulated by Paracoccidioides brasiliensis
Paracoccidioidomycosis (PCM) is an endemic mycosis in Latin America caused by the dimorphic fungus Paracoccidioides brasiliensis. The pattern of the immune responses to P. brasiliensis determines the disease progression and clinical outcome. Innate immune response is mediated by phagocytic cells, such as macrophage and neutrophils, which ingest and kill inva
