Journal ArticleDOI
Structure, chemical and photochemical reactivity and biological activity of some ruthenium amine nitrosyl complexes
TL;DR: In this article, the site of the reduction [Ru(NO)]3++e−→[Ru( NO)]2+ was assigned to the NO ligand based on molecular orbital (MO) analysis and on reduction product analysis.
Journal ArticleDOI
Plasma levels of cortisol and glucose in response to capture and tank transference in Rhamdia quelen (Quoy & Gaimard), a South American catfish
Leonardo José Gil Barcellos,V. M. Woehl,Guillermo Federico Wassermann,Rosmari Mezzalira Quevedo,I. Ittzés,Marta Helena Krieger +5 more
TL;DR: Males and females of Rhamdia quelen were subjected to capture and tank transference in order to evaluate the stress response, with cortisol values reaching a peak in one hour after stress.
Journal ArticleDOI
Steroid profiles in cultured female jundiá, the Siluridae Rhamdia quelen (Quoy and Gaimard, Pisces Teleostei), during the first reproductive cycle.
Leonardo José Gil Barcellos,Guillermo Federico Wassermann,Alexander P. Scott,V. M. Woehl,Rosmari Mezzalira Quevedo,István Ittzés,Marta Helena Krieger,Francisco Lulhier +7 more
TL;DR: Two distinct peaks of progestogens were detected, corresponding to the two spawning episodes, suggesting that one or more of these steroids might act as the "maturational-inducing steroid" in jundiá.
Journal ArticleDOI
In vivo effects of the controlled NO donor/scavenger ruthenium cyclam complexes on blood pressure☆
Fabiana G. Marcondes,Alessander A. Ferro,Adriana Souza-Torsoni,Marie Sumitani,Mike Clarke,Douglas Wagner Franco,Elia Tfouni,Marta Helena Krieger +7 more
TL;DR: Cyclam-NO showed an hypotensive effect around 20 times longer than SNP in either normotensive or hypertensive rats, which was completely inhibited by methylene blue or carboxy-PTIO.
Journal ArticleDOI
Characterization of the hypotensive effect of S-nitroso-N-acetylcysteine in normotensive and hypertensive conscious rats.
Kelly Fabiane S. Ricardo,Silvia Mika Shishido,Marcelo Ganzarolli de Oliveira,Marta Helena Krieger +3 more
TL;DR: The hypotensive effect of the RSNO S-nitroso-N-acetylcysteine (SNAC) in normotensive and hypertensive conscious rats is characterized, showing that SNAC acts by both cG MP-dependent and cGMP-independent pathways.
