Differential serotonergic modulation of two types of aggression in weakly electric fish.

Frontiers in behavioral neuroscience

Zubizarreta L, Perrone R, Stoddard PK, Costa G, Silva AC.
PMID: 23181014
Front Behav Neurosci. 2012 Nov 19;6:77. doi: 10.3389/fnbeh.2012.00077. eCollection 2012.

Agonistic aggression has provided an excellent framework to study how conserved circuits and neurochemical mediators control species-specific and context-dependent behavior. The principal inhibitory control upon aggression is serotonin (5-HT) dependent, and the activation of 5-HT(1A) receptors is involved in...

Comparison of the in vivo and in vitro genotoxicity of glyphosate isopropylamine salt in three different organisms.

Genetics and molecular biology

Alvarez-Moya C, Silva MR, Ramírez CV, Gallardo DG, Sánchez RL, Aguirre AC, Velasco AF.

Galactose-1-phosphate uridylyltransferase (GALT) is a key enzyme in galactose metabolism, particularly important in the neonatal period due to ingestion of galactose-containing milk. GALT deficiency results in the genetic disorder classic galactosemia, whose pathophysiology is still not fully elucidated. Whereas...
