Ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermiogenesis
(2000-10-01)
The spermiogenesis and the spermatozoon ultrastructure of Sorubim lima were studied. Our observations showed that early spermatids are round-shaped cells, have spherical nucleus with diffuse chromatin, small quantity of ...
Damage to the central amygdala produces differential encephalic c-fos expression in the water deprivation-partial rehydration protocol
(Elsevier B.V., 2009-12-04)
We investigated the effects of electrolytic damage to the central nucleus of the amygdala on brain c-fos expression and 0.3 M NaCl intake of adult male rats (n=6-12/group) submitted to a cycle of 36 h of water deprivation ...

Action of andiroba oil and permethrin on the central nervous and reproductive systems of Rhipicephalus sanguineus (Latreille, 1806) (Acari: Ixodidae) ticks females. A confocal study
(2013-10-01)
Research for acaricides with lower toxicity and impact on the environment has been intensified. An alternative would be the use of natural compounds or of synthetic products in lower concentrations than the ones sold ...
