(Universidade Tecnológica Federal do ParanáCampo Mourao, 2012-12-10)
The objective of this Completion of Course Work was to evaluate the performance of an anaerobic fixed channel reactor with polyurethane foams and expanded clay as a medium for the treatment of sewage. For this, a bench ...
Removal of Escherichia coli from well water using continuous laminar flow in a channel system containing PPy/Cu modified electrodes
(IWA Publishing, 2018-12)
Polypyrrole (PPy) films modified with copper species were used for disinfection of well water contaminated with Escherichia coli (E. coli). For that purpose a laboratory-scale continuous flow system with a parallel plate ...
Lipopolymers and lipids from lung surfactants in association with N-acetyl-l-cysteine: Characterization and cytotoxicity
(Elsevier Ireland, 2020-09)
In the present work, we obtained polymeric diacetylene liposomes that can associate N-Acetyl-L-Cysteine (NAC),a broad spectrum mucolytic. The reason for studying these formulations is that they could be applied in thefuture ...
Customized design of electronic noses placed on top of air-lift bioreactors for in situ monitoring the off-gas patterns
(Springer, 2012-06)
A specially designed electronic nose was coupled to an air-lift bioreactor in order to perform on-line monitoring of released vapors. The sensor array was placed at the top of the bioreactor sensing the headspace in ...
Angiogenic activity by spleen cell supernatants from tumor‐bearing and tumor‐resected mice
(Wiley, 1988-01)
Supernatants of cultured spleen cells (SCS) from small tumor‐bearing mice (STBM) and large tumor‐bearing mice (LTBM) are able to enhance tumor growth as well as accelerate tumor takes in vivo when inoculated 24 h before ...
Endogenous glucocorticoids attenuate Shiga toxin-2-induced toxicity in a mouse model of haemolytic uraemic syndrome
(Wiley Blackwell Publishing, Inc, 2003-02)
The concept that during an immune challenge the release of glucocorticoids (GC) provides feedback inhibition on evolving immune responses has been drawn primarily from studies of autoimmune and/or inflammatory processes ...
Azospirillum brasilense and Azospirillum lipoferum Hydrolyze Conjugates of GA20 and Metabolize the Resultant Aglycones to GA1 in Seedlings of Rice Dwarf Mutants
(American Society of Plant Biologist, 2001-10)
Azospirillum species are plant growth-promotive bacteria whose beneficial effects have been postulated to be partially due to production of phytohormones, including gibberellins (GAs). In this work, Azospirillum brasilense ...
