1. Changes in digestive enzymes activities during the initial ontogeny of wolf cichlid, Parachromis dovii (Perciformes: Cichlidae)
ABSTRACT Wolf cichlid, Parachromis dovii, is a species with a high potential for aquaculture in Central America; however, the knowledge of the digestive physiology in larvae period is limited. For these reason, this study evaluated the changes on digestive enzymes (alkaline and acid proteases, trypsin, chymotrypsin, aminopeptidase, carboxypeptidase, lipases,

2. Digestibility, growth, blood chemistry, and enzyme activity of juvenile Oreochromis niloticus fed isocaloric diets containing animal and plant byproducts
ABSTRACT In this work, we studied the digestibility, growth, blood chemistry, and enzyme activity of Nile tilapia (Oreochromis niloticus) juveniles (0.95±0.18 g) using different animal (fish silage meal, whey meal, bovine blood meal, and red crab meal) and plant (extruded bean, extruded chickpea meal, coconut paste, Jatropha curcas meal, and chickpea meal)

3. Avaliação do potencial genotóxico do 51Cr2O3, marcador de digestibilidade, por meio da frequência de anormalidades nucleares em tilápias do Nilo (Oreochromis niloticus L.) / The evaluation of genotoxic potential of 51Cr2O3, a digestibility marker, by the frequency of nuclear abnormalities in Nile tilapia (Oreochromis niloticus L.)
Tilapia is the common name of a large number of species of cichlid fish. In aquaculture, this is one of the most profitable fish, since it presents lower feed conversion than other fish. The chromium oxide has been used as a marker for digestibility because it is inert and not alter the biological process of dietary intake. The use of radioactive form of chr

4. Estratégias e fisiologia do consumo e digestão de esponjas (Porifera) por Echinaster brasiliensis (Echinodermata: Asteroidea) / Strategies and physiology of the consumption and digestion of sponges (Porifera) by Echinaster brasiliensis (Echinodermata: Asteroidea)
Sponges are sessile and have a skeleton made of microscopic inorganic elements (spicules), collagen fibers and/or combinations of these two components. Although without clear physical defenses such as shells or spines, they are not preyed upon, and this is attributed mainly to the presence of active secondary metabolites. Recently, a role of skeletal compone

6. Immune homeostasis to microorganisms in the guts of triatomines (Reduviidae): a review
Bacteria, fungi and parasites are in constant contact with the insect gut environment and can influence different aspects of the host gut physiology. Usually, some of these microorganisms develop and survive in the digestive tract. Therefore, the gut environment must be able to tolerate certain populations of these organisms for the establishment of interact

7. Enzimas de organismos aquÃticos e suas aplicaÃÃes fisiolÃgicas
In the last years, there has been a general increase in human demand for fishery products, followed by a significant increase in the world production of aquatic organisms. The growth of fishery industry generates, as consequence, large amounts of wastes and by-products rich in biomolecules, which are discharged into envioronment. Fishery wastes can be used i

8. Nervous system x others : diagnosis of university first-year students prior knowledge / Sistema nervoso X demais sistemas : diagnostico do conhecimento previo em alunos ingressantes no ensino superior
Knowledge in Neuroanatomy is crucial to understand others "neuro" subjects such as Physiology, Pathology, Surgery and Imaging for students in health sciences. However, teaching Neuroanatomy, is not an easy task and although students often find the brain to be a marvel of complexity they always have difficulty in learning and sometimes they even refuse to tak

10. Proteases digestivas do hepatopÃncreas dos camarÃes marinhos Farfantepenaeus subtilis e Farfantepenaeus paulensis
Farfantepenaeus subtilis and Farfantepenaeus paulensis are native shrimp species and appear as an alternative to Litopenaeus vannamei cultivation, which represents more than 90% of the farmed shrimp in the Northeast of Brazil. Proteases from hepatopancreas of F. subtilis juveniles and adults and F. paulensis juveniles were studied according to the following

11. Intestinal molecular physiology of Dysdercus peruvianus (Hemiptera) / Fisiologia molecular intestinal de Dysdercus Peruvianus (Hemiptera)
After identification of cathepsins L in vitro assays and in zimograms we began to purify this enzyme in insect midgut. The region V2 was selected as a source of material for purifying a cysteine proteinase because it contains most of the activity of that proteinase. After several attempts to purify this proteinase, an effective process was developed that avo

12. Metamorphosis in the midgut of bees : proliferation or cellular migration? / Metamorfose do intestino medio de abelhas : proliferação ou migração celular?
Bees are holometabolus insects, since they present complete metamorphosis. During the metamorphosis of the insects the gut is completely remodeled. Few studies emphasize aspects of the renewal of the epithelium of bees midgut during metamorphosis. Studies that describe digestive cell proliferation are lacking in images of mitosis. This research is a contri
