Artificial selection, pre-release diet, and gut symbiont inoculation effects on sterile male longevity for area-wide fruit-fly management
(Wiley, 2015-12)
Longevity is an important life-history trait for successful and cost-effective application of the sterile insect technique. Furthermore, it has been shown that females of some species – e.g., Anastrepha ludens (Loew) ...
Conjugal transfer of a Sinorhizobium meliloti cryptic plasmid evaluated during a field release and in soil microcosms
(Elsevier France-editions Scientifiques Medicales Elsevier, 2013-03)
Horizontal gene transfer (HGT) is a central evolutionary mechanism that mediates the diversification and adaptation of bacteria in general and of rhizobia in particular. The few quantitative data on the conjugal transfer ...
Alternative mechanism for the evaluation of indole-3-acetic acid (IAA) production by Azospirillum brasilense strains and its effects on the germination and growth of maize seedlings
(Springer, 2013-09)
We evaluated the production of indole-3-acetic acid (IAA) by Azospirillum brasilense strains in vitro (cell culture supernatants) and in vivo (stems and roots of maize seedlings) to clarify the role of this phytohormone ...
Acute hypercortisolemia inhibits innate immune parameters in Piaractus mesopotamicus experimentally infected with Aeromonas hydrophila
(2020-06-30)
Cortisol is a key modulator of the immune response in fish, and considered an essential molecule for adaptation of animals to stress and overcoming the stressor. Antagonist effects, pro and anti-inflammatory have been ...
Inoculation of Triticum Aestivum L. (Poaceae) with plant-growth-promoting fungi alleviates plant oxidative stress and enhances phenanthrene dissipation in soil
(MDPI, 2021)
Polycyclic aromatic hydrocarbons (PAHs) are strong toxic compounds mainly released to the environment during combustion of fossil fuels, and have strong toxic effects on living organisms, with soil being one of their main ...
Experimental murine mycobacteriosis: evaluation of the functional activity of alveolar macrophages in thalidomide- treated mice
(Associação Brasileira de Divulgação Científica (ABRADIC), 2004-04-01)
Thalidomide is a selective inhibitor of tumor necrosis factor-alpha (TNF-alpha), a cytokine involved in mycobacterial death mechanisms. We investigated the role of this drug in the functional activity of alveolar macrophages ...
β-glucan modulates cortisol levels in stressed pacu (Piaractus mesopotamicus) inoculated with heat-killed Aeromonas hydrophila
(2019-10-01)
In this study, we show that β-glucan can modulate cortisol release in fish. We simulated a common situation in aquaculture: the transport of fish followed by contact with an opportunistic pathogen and observed what effect ...
Effects of Mikania glomerata Leaf Extract on Experimental Bothropoides jararaca Envenomation in Wistar Rats
(Univ Fed Rio Grande Do Sul, 2017-08-14)
Background: Bothropic envenomation represents the most common ophidic accident worldwide, compared to other snakebites of medical interest. Bothropic venom has proteolytic, vasculotoxic, clotting and/or hemorrhagic actions ...
Addition of waste and introduction of microorganisms after 45 years of soil degradation
(2018-07-01)
The construction of hydroelectric power plants (HPP) may result in environmental problems, such as extensive areas of exposed subsoil and conditions of extreme degradation. These areas require alternative that minimize ...
