1. VASCULAR FUNCTION AND NITRITE LEVELS IN ELDERLY WOMEN BEFORE AND AFTER HYDROGYMNASTICS EXERCISES
RESUMO A prática regular de exercício físico pode reduzir o estresse oxidativo e os fatores de risco para doenças cardiovasculares. O objetivo deste estudo foi avaliar nível de nitrito sanguíneo, alterações na resistividade de artérias cerebrais e no colesterol de idosas submetidas a treinamento de hidroginástica. Quarenta mulheres formaram a amost

2. Phagocytosis and nitric oxide production by peritoneal adherent cells in response to Candida albicans in aging: a collaboration to elucidate the pathogenesis of denture stomatitis
Abstract Elderly denture wearers are commonly affected by Candida-associated denture stomatitis (DS), an inflammatory process of the oral mucosa strongly associated with Candida spp and other microorganisms, as well as local and systemic factors. The impaired immune response against pathogens is among the inherent host factors that have been also associated

3. Brown seaweed Padina gymnospora is a prominent natural wound-care product
ABSTRACT Seaweeds are related to anti-inflammatory, anti-bacterial and anti-noceptive effects. This work aimed to verify the potential of seaweed Padina gymnospora (Kützing) Sonder 1871 to improve wound healing in vitro. P. gymnospora was collected at a bethonic area in Espirito Santo. Methanolic extract of P. gymnospora was obtained by percolation. To dete

4. Nitric oxide production by Peromyscus yucatanicus (Rodentia) infected with Leishmania (Leishmania) mexicana
Peromyscus yucatanicus (Rodentia: Cricetidae) is a primary reservoir of Leishmania (Leishmania) mexicana (Kinetoplastida: Trypanosomatidae). Nitric oxide (NO) generally plays a crucial role in the containment and elimination of Leishmania. The aim of this study was to determine the amount of NO produced by P. yucatanicus infected with L. (L.) mexicana. Subcl

5. DESENVOLVIMENTO E VALIDAÇÃO DE UM MÉTODO AUTOMATIZADO PARA A QUANTIFICAÇÃO DOS NÍVEIS SÉRICOS DE NITRITO/NITRATO / DEVELOPMENT AND VALIDATION OF AN AUTOMATED METHOD FOR THE MEASUREMENT OF SERUM LEVELS OF NITRITE/NITRATE
O óxido nítrico (NO) é um radical livre reativo, agindo como uma molécula mensageira, mediando diversas funções, incluindo vasodilatação, inibição da agregação plaquetária e neurotransmissão. Pelo fato deste radical possuir uma meia-vida curta, a sua determinação torna-se difícil, consequentemente, a mensuração de seus metabólitos nitrito

6. Cells and mediators of inflammation (C-reactive protein, nitric oxide, platelets and neutrophils) in the acute and convalescent phases of uncomplicated Plasmodium vivax and Plasmodium falciparum infection
The haematological changes and release of soluble mediators, particularly C-reactive protein (CRP) and nitric oxide (NO), during uncomplicated malaria have not been well studied, especially in Brazilian areas in which the disease is endemic. Therefore, the present study examined these factors in acute (day 0) and convalescent phase (day 15) patients infected

7. Antimicrobial peptides and nitric oxide production by neutrophils from periodontitis subjects
Neutrophils play an important role in periodontitis by producing nitric oxide (NO) and antimicrobial peptides, molecules with microbicidal activity via oxygen-dependent and -independent mechanisms, respectively. It is unknown whether variation in the production of antimicrobial peptides such as LL-37, human neutrophil peptides (HNP) 1-3, and NO by neutrophil

8. Correlation between total nitrite/nitrate concentrations and monoamine oxidase (types A and B) and semicarbazide-sensitive amine oxidase enzymatic activities in human mesenteric arteries from non-diabetic and type 2 diabetic patients
The aim of this study was to determine the correlation between total nitrite/nitrate concentrations (NOx) and the kinetic parameters of monoamine oxidase enzymes (MAO-A and MAO-B) and semicarbazide-sensitive amine oxidase (SSAO) in human mesenteric arteries. Arteries were from non-diabetic and type 2 diabetic patients with sigmoid or rectum carcinoma for who

9. Piper sarmentosum increases nitric oxide production in oxidative stress: a study on human umbilical vein endothelial cells
OBJECTIVE: Nitric oxide produced by endothelial nitric oxide synthase (eNOS) possesses multiple anti-atherosclerotic properties. Hence, enhanced expression of eNOS and increased Nitric oxide levels may protect against the development of atherosclerosis. Piper sarmentosum is a tropical plant with antioxidant and anti-inflammatory activities. This study aimed

10. Impact of galectin-1 on the evolution of acute experimental Trypanosoma cruzi infection / Avaliação da participação da galectina-1 na evolução da infecção experimental aguda por Trypanosoma cruzi
Galectin-1 (Gal-1) is a -galactoside-binding protein and participates in several biological processes, including modulation of immune response. In the literature, there are several reports about the potential therapeutic use of Gal-1 for autoimmune diseases, inflammatory, degenerative and infectious diseases. However, there are few reports on the involvement

11. InfluÃncia da desnutriÃÃo neonatal em parÃmetros imunes de ratos treinados e submetidos ao estresse de contenÃÃo
Objective: The neonatal malnutrition (NM) influence was analyzed in immune parameters of 36 Wistar young adults (60 days) male rats, trained or not and submitted to the contention stress (CS). Methods: In the nurtured groups (casein 17%) and malnourished (8%) they were appraised total leukocytes (hemocytometer) and differentiate (blood smears); hemoglobin (c

12. Efeito dos extratos de Harpagohytum procumbens (garra-do-diabo) e suas frações na atividade da COX-1 e COX-2 e na produção de NO em sangue total / Effects of harpagophytum procumbens (devils claw) extracts and its fractions on Cox-1 and Cox-2 activity and nitric oxide production in whole blood.
OBJECTIVE: The present study evaluated the effect of H. procumbens extracts and its fractions on COX-1 and COX-2 activity and NO production in whole blood assays of volunteers and OA patients. METHODS: The COX-1 and COX-2 activity was quantified as platelet TXB2 production in blood clotting and as PGE2 production in heparinized LPS-stimulated whole blood, re
