Control of white mold of dry bean and residual activity of fungicides applied by chemigation
(2017-04-01)
Sclerotinia sclerotiorum is a necrotrophic fungal pathogen that causes white mold of dry bean (Phaseolus vulgaris L.). Chemigation with fungicides is used for disease control, but effectiveness of this application method ...
Immunomodulatory activities associated with beta-glucan derived from Saccharomyces cerevisiae
(Acad Sciences Czech Republic, Inst Physiology, 2005-01-01)
In this study we investigated the effect of beta-glucan derived from Saccharomyces cerevisiae on fungicidal activity, cytokine production and natural killer activity. Spleen and peritoneal cells from female C57BL/6 mice, ...
Communication or toxicity: What is the effect of cycloheximide on leaf-cutting ant workers?
(2017-12-01)
Leaf-cutting ants are insects that use plant material to grow fungus from which they feed. These fungus-growing ants perform various behavioral activities to establish an environment conducive to the fungus. Among these ...
The immunomodulatory effect of propolis on receptors expression, cytokine production and fungicidal activity of human monocytes
(Wiley-Blackwell, 2014-10-01)
ObjectivesPropolis is a beehive product and its immunomodulatory action has been documented; however, little is known concerning its mechanisms of action on human cells. Propolis influence on the initial events of the ...
Cinnamic acid is partially involved in propolis immunomodulatory action on human monocytes
(2013-06-12)
Propolis is a beehive product used in traditional medicine due to its biological properties. It shows a complex chemical composition including phenolics, such as cinnamic acid (Ci). The mechanisms of action of propolis ...
Effects of a fungicide formulation on embryo-larval development, metamorphosis, and gonadogenesis of the South American toad Rhinella arenarum
(Elsevier Science, 2016-07)
Sublethaltoxicity ofthe formulated fungicide Maxim® XL on embryonic, larval and juvenile development of Rhinella arenarum was evaluated by means of standardized bioassays. Maxim® XL, one ofthe most used fungicides in ...
High expression of human monocyte iNOS mRNA induced by Paracoccidioides brasiliensis is not associated with increase in NO production
(Elsevier B.V., 2012-10-01)
In this study we investigated the role of nitric oxide (NO) in monocyte fungicidal activity against Paracoccidioides brasiliensis. We found that cells primed with IFN-gamma, TNF-alpha or GM-CSF and challenged with a ...
