Ethylene triggers salt tolerance in maize genotypes by modulating polyamine cat...
Freitas, Valdineia Soares; Miranda, Rafael de Souza; Costa, José Hélio; Oliveira, Daniel Farias de; Paula, Stelamaris de OliveiraThe current study was undertaken to investigate if there is a relationship between metabolisms of ethylene and polyamines in the processes of salinity acclimation of salt-tolerant and salt-sensitive maize genotypes. Biphasic ethylene production (at 5.5 and 12.5 h) was registered only in salt-sensitive plants during NaCl exposure. In the salt-tolerant genotype, the unique ethylene peak at 5.5 h was closely relat...
Glutamine and Alanyl-Glutamine increase RhoA expression and reduce clostridium ...
Santos, Ana Angélica Queiroz Assunção; Braga Neto, Manuel Bonfim; Oliveira, Marcelo Róseo de; Freire, Rosemayre Souza; Barros, Eduardo BedêClostridium difficile is a major cause of antibiotic-associated colitis and is associated with signicant morbidity and mortality. Glutamine (Gln) is a major fuel for the intestinal cell population. Alanyl-glutamine (Ala-Gln) is a dipeptide that is highly soluble and well tolerated. IEC-6 cells were used in the in vitro experiments. Cell morphology was evaluated by atomic force microscopy (AFM) and scanning elec...
Metabolic acidosis aggravates experimental acute kidney injury
Magalhães, Patrícia Andréa da Fonseca; Brito, Teresinha Silva de; Freire, Rosemayre Souza; Silva, Moisés Tolentino Bento da; Santos, Armênio Aguiar dosims Ischemia/reperfusion (I/R) injury and metabolic acidosis (MA) are two critical conditions that may simultaneously occur in clinical practice. The result of this combination can be harmful to the kidneys, but this issue has not been thoroughly investigated. The present study evaluated the influence of low systemic pH on various parameters of kidney function in rats that were subjected to an experimental mode...
Avaliação do feito citoprotetor da amifostina na cardiotoxicidade aguda induzid...
Freire, Rosemayre SouzaDoxorubicin (DOX) is an antineoplasic anthracyclic agent used on the treatment of several solid tumors and hematological cancers. DOX-induced cardiotoxicity has been studied for decades as a limiting factor on the anticancer therapy with this drug. Despite the current knowledge concerning the mechanisms of DOX-induced cardotoxicity, its pathophysiology is still not clear. Purpose: To evaluate of the amifostine ...
