BACKGROUND Dialyzable leukocyte extracts (DLEs) contain molecules smaller than 10 kDa with biological activity in receptor organisms. Primarily, they participate in the regulation of the Th1 immune response, which is essential for the control of several intracellular infections, such as toxoplasmosis. Th...

A alface (Lactuca sativa L.) possui
grande importância na alimentação
humana, como fonte de vitaminas
e sais minerais, além de possuir
baixo valor calórico. Apesar do cultivo
hidropônico estar em expansão no
Brasil e ser bastante vantajoso, não
há uma legislação específica dos nutrientes

Atualmente no Peru, o processamento
para obter a polpa de cherimoia
é muito delicado e complexo
devido ao fato deste fruto precisar
de condições específicas para evitar
a sua deterioração durante a fabricação,
pois a carga de micro-organismos
não pode ser reduzida pela

Artemisia genus (family Asteraceae) has been widely used as medicines and cosmetic. The chemical compositions of essential oils extracted from five Artemisia species (A. anethoides, A. giraldii, A. roxburghiana, A. rubripes and A. sacrorum) were analyzed and the repellent activities of five essential oil...

The flavonoid 3,5-dihydroxy-7-methoxyflavanone ((-)-alpinone) isolated from sticky resinous exudate of Heliotropium huascoense was evaluated as immunostimulatory in mammalian cells . Preliminary observations had showed that (-)-alpinone had increased the expression levels of pro-inflammatory cytokine tra...
Essential oils from leaves of Ocotea limae and Ocotea gardneri species were analyzed by GC-FID and GC-MS. The analysis revealed the presence of 48 components accounting for 98.1 ± 1.3% e 98.0 ± 0.5% of the essential oils from the O. limae and O. gardneri, respectively. The oils were characterized by hi...
Abstract Purpose: Topical hypothermia and local ischemic preconditioning have been shown to reduce renal ischemia-reperfusion (I/R) injury individually. We examined whether combination of both strategies lessens renal I/R injury. Methods: Post right nephrectomy, 40 male Wistar rats were randomly assi...

ABSTRACT Introduction: Plaque accumulation and bond failure are drawbacks of orthodontic treatment, which requires composite for bonding of brackets. As the antimicrobial properties of TiO2 nanoparticles (NPs) have been proven, the aim of this study was to evaluate the antimicrobial and mechanical prop...

Abstract: The pH of the skin is slightly acidic (4.6 to 5.8) which is important for appropriate antibacterial, antifungal, constitution of barrier function, as well as structuring and maturation of the stratum corneum. This study aimed to evaluate the pH of the main commercial moisturizers and liquid soa...
Abstract Considering that the main route of Mycobacterium leprae transmission is the upper respiratory tract, detection of salivary antibodies can be a useful tool for diagnosing early infection. The study aimed to analyze salivary anti-PGL-1 IgA and IgM antibodies in 169 children aged 4-16 years old, wh...
