Inhibiting effect of citric acid on the pitting corrosion of tin
(Kluwer Academic Publ, 1999-01-01)
Potentiostatic and potentiodynamic studies were carried out to establish the inhibiting effects of citric acid on the pitting corrosion of tin. The critical potential (E-crit), which leads to pitting or general corrosion, ...
Atividade antifúngica de extratos de plantas a Colletotrichum gloeosporioides
(Universidade Estadual de Maringá (UEM), Pro-reitoria Pesquisa Pos-graduacao, 2008-01-01)
The present work aimed to evaluate the effect fungitoxic of plant extracts on the mycelial growth and on the spores germination of C. gloeosporioides. The plant extracts were obtained starting from dried ground plants, ...
In vitro characterization of intra-generic inhibition of growth in Salmonella typhimurium
(1991-10-15)
The intra-generic inhibition of bacterial growth observed previously in vivo and in vitro with strains of Salmonella, Citrobacter and E. coli was studied in vitro using S. typhimurium strain F98. There was complete inhibition ...
IN-VITRO INHIBITION OF SPORES GERMINATION OF ALTERNARIA-SOLANI BY 3 FUNGICIDES
(Soc Brasileira Microbiologia, 1994-01-01)
In vitro inhibition of the of spores germination of Alternaria solani by iprodione, chlorothalonil, and anilazine at different dosages was studied. The highest concentration of active ingredient studied for each fungicide ...
Nucleus isthmi and control of breathing in amphibians
(Elsevier B.V., 2004-11-15)
Despite recent advances, the mechanisms of neurorespiratory control in amphibians are far from understood. One of the brainstem structures believed to play a key role in the ventilatory control of anuran amphibians is the ...
Salacia campestris root bark extract: peroxidase inhibition, antioxidant and antiradical profile
(Universidade de São Paulo (USP), Conjunto Quimicas, 2009-01-01)
Reactive oxygen species (ROS) and free radical species have been implicated in initiating or accompanying many diseases in living organisms; there is thus, a continual need for antioxidants molecules to inactivate ROS/free ...

(Elsevier B.V., 2005-07-15)
Suramin, a synthetic polysulfonated compound, developed initially for the treatment of African trypanosomiasis and onchocerciasis, is currently used for the treatment of several medically relevant disorders. Suramin, ...
Design and synthesis of peptides from bacterial ParE toxin as inhibitors of topoisomerases
(Elsevier France-editions Scientifiques Medicales Elsevier, 2012-08-01)
Toxin-antitoxin (TA) proteic systems encode a toxin and an antitoxin that regulate the growth and death of bacterial cells under various stress conditions. The ParE protein is a toxin that inhibits DNA gyrase activity and ...
Chicken embryo related (CER) cell line for quantification of rabies neutralizing antibody by fluorescent focus inhibition test
(Elsevier B.V., 2006-03-01)
Levels of rabies virus neutralization antibody in sera from vaccinated dogs and cattle were either measured by mouse neutralization test (MNT) or by rapid fluorescent focus inhibition test (RFFIT), performed on CER monolayers. ...
Inhibition of the symbiotic fungus of leaf-cutting ants by coumarins
(2005-05-01)
Leaf-cutting ants are known to be a serious pest for agriculture due to the high amounts of vegetal matter from crops used by them in order to cultivate a symbiotic fungus on which they rely for food and enzymes. The ...
