CONTROL OF ADIPOSE-TISSUE LIPOLYSIS IN ECTOTHERM VERTEBRATES
(Amer Physiological Soc, 1992-10-01)
Lipolytic activity of fish (Hoplias malabaricus), toad (Bufo paracnemis), and snake (Philodryas patagoniensis) adipose tissue was investigated in vivo and in vitro. Catecholamines or glucagon did not affect the release of ...

Natural infection with zoonotic subtype of Cryptosporidium parvum in Capybara (Hydrochoerus hydrochaeris) from Brazil
(Elsevier B.V., 2007-06-20)
A total of 145 capybara (Hydrochoerus hydrochaeris) fecal samples from the state of Sdo Paulo, Brazil, were screened for Cryptosporidium spp. oocysts using the malachite green method. Eight samples (5.52%) showed positive ...
Physiology of temperature regulation: Comparative aspects
(Elsevier B.V., 2007-07-01)
Few environmental factors have a larger influence on animal energetics than temperature, a fact that makes thermoregulation a very important process for survival. In general, endothermic species, i.e., mammals and birds, ...

Considering the lack of detailed information about the morphology of paca, which is the second largest rodent of Brazilian's fauna, with excellent meat quality and, due to the importance of the common integument, we described ...
Identification of phospholipase C zeta in normospermic and teratospermic domestic cat sperm
(2013-10-15)
In mammalian species, oocyte activation is initiated by oscillations in the intracellular concentration of free calcium ([Ca2+]i), which are also essential to allow embryonic development. To date, evidence supporting the ...

The development of the stomach of domestic mammals is a complex process, especially in ruminants. The aim of this study was to analyze this organ during prenatal period. Omasum samples of Nelore fetuses (Bos taurus indicus) ...
Phosphorylation of Histone H3S10 in Animal Chromosomes: Is There a Uniform Pattern?
(Karger, 2011-01-01)
Phosphorylation of serine 10 in histone H3 (H3S10ph) has been extensively analyzed and appears to be a conserved chromatin change associated with chromosome condensation in different eukaryotic organisms. In this work, we ...
