Comparative analysis of the morphology and histochemistry of the duodenum of the coypu (Myocastor coypus bonariensis) during its prenatal and postnatal development
(Elsevier, 2016-02)
The objective of this study focused on the comparative morphological and histochemical analysis of the duodenum of fetuses, juveniles and adult coypu (Myocastor coypus bonariensis), the major socioeconomic wildlife resource ...
Deleterious effects of wastewater on the health status of fish: a field caging study
(Elsevier Science, 2014-03)
tWe carried out a caging field experiment to assess the potential effects of an untreated sewage effluenton the health status of Prochilodus lineatus. We analyzed multiple biomarker responses, which includedmorphological ...
Bovine plasma protein as an alternative protein source in extruded aquafeeds for Piaractus mesopotamicus (pacú) at two fattening stages
(Wiley Blackwell Publishing, Inc, 2019-11-20)
An 84‐day feeding trial was conducted to evaluate the addition of bovine plasma protein concentrate (BPP) as a full replacement of fish meal (FM) in extruded aquafeeds for the fish Piaractus mesopotamicus at two fattening ...
Sperm morphology of two marine neogastropods from the southwestern Atlantic Ocean (Caenogastropoda: Volutidae and Olividae)
(Bailey-Matthews Shell Museum, 2009-10)
The testes of Caenogastropoda typically produce two types of spermatozoa, euspermatozoa and paraspermatozoa. The structures of both morphological forms of sperm contribute to our understanding of reproductive biology, and ...
The Mas receptor mediates modulation of insulin signaling by angiotensin-(1-7)
(Elsevier Science, 2012-08)
Angiotensin (Ang)-(1-7) stimulates proteins belonging to the insulin signaling pathway and ameliorates the Ang II negative effects at this level. However, up to date, receptors involved and mechanisms behind these observations ...
Starch synthesis in ostreococcus tauri: The starch-binding domains of starch synthase III-B are essential for catalytic activity
(Frontiers Research Foundation, 2018-10)
Starch is the major energy storage carbohydrate in photosynthetic eukaryotes. Several enzymes are involved in building highly organized semi-crystalline starch granules, including starch-synthase III (SSIII), which is ...
Multiple-biomarker approach in the assessment of the health status of a novel sentinel mussel Brachidontes rodriguezii in a harbor area
(Pergamon-Elsevier Science Ltd, 2019-03)
The objective of this study is to analyze whether a combination of biomarkers at different levels of biological complexity could be used to assess the health status of a population of Brachidontes rodriguezii associated ...
Simultaneous heterotrophic nitrification and aerobic denitrification of wastewater in granular reactor: Microbial composition by next generation sequencing analysis
(Elsevier Ltd, 2020-08)
Dairy effluents contain limited nitrogen for biological treatment. In the present study a cheese whey wastewaterwas supplemented with ammonia to obtain suitable COD:N ratios. The effects of the organic load and micronutrientson ...
Identification and analysis of OsttaDSP, a phosphoglucan phosphatase from Ostreococcus tauri
(Public Library of Science, 2018-01)
Ostreococcus tauri, the smallest free-living (non-symbiotic) eukaryote yet described, is a unicellular green alga of the Prasinophyceae family. It has a very simple cellular organization and presents a unique starch granule ...
Protein and cellulose level in diet. Effects on enzymatic activity, metabolite and amino acid profiles in freshwater anomurans Aegla uruguayana (Decapoda: Anomura)
(Wiley Blackwell Publishing, Inc, 2019-12-29)
The aims of this study were to evaluate the short-term effects of artificial diets with different protein: cellulose ratios (D1 = 60:0, D2 = 45:15 and D3 = 30:30) on the enzymatic activity and metabolite profile and to ...
