Fibroblast growth factor 2 regulates cumulus differentiation under the control of the oocyte
Barros, Rodrigo G.; Lima, Paula F. ; Soares, Ana Caroline S. ; Sanches, Lorena ; ; Buratini, Jose (Journal Of Assisted Reproduction And Genetics, 2019) [Artigo]
PurposeWe first assessed regulation of FGF2 expression in cumulus cells by FSH and oocyte-secreted factors during in vitro maturation (IVM). Then, we tested the hypothesis that FGF2 regulates meiotic progression, cumulus ... -
Low cholesterol is not always good: low cholesterol levels are associated with decreased serotonin and increased aggression in fish
Aguiar, Ariane; Giaquinto, Percilia Cardoso (Biology Open, 2018) [Artigo]
The inverse relationship between serum cholesterol and levels of aggression led to the cholesterol-serotonin hypothesis. According to this hypothesis, low dietary cholesterol intake leads to depressed central serotonergic ... -
Reproductive evaluations in female rat offspring exposed to metformin during intrauterine and intrauterine/lactational periods
(Reproductive Toxicology, 2019) [Artigo]Metformin (MET) is a widely-used drug for the treatment of type 2 diabetes mellitus and gestational diabetes. It is known that metformin crosses the placenta and can to be transferred through milk. In vitro studies show ... -

PurposeTo assess the effect of body mass index (BMI) on morphokinetic parameters of human embryos evaluated with time-lapse technology during in vitro culture.MethodsA retrospective analysis of ART cycles utilizing time-lapse ... -
Preference for heights of feeding troughs in mares: a pilot study
Luz, M. P. F.; Maia, C. M. ; Arruda, L. A. S. ; Delagracia, M. F. ; Filho, J. N. P. P. (Animal Welfare, 2019) [Artigo]
Preferences for the height of feeding troughs of seven mares were evaluated and, as awareness of surroundings when feeding is adaptive for horses, the relationship between preference responses and attention behaviours was ... -

Fibroblast growth factor 18 regulates steroidogenesis in fetal bovine ovarian tissue in vitro
Silva, Rubia Bueno da; ; Caixeta, E. S. ; Castilho, Anthony C. ; Amorim, R. L. ; ; ; Buratini, J. (Molecular Reproduction And Development, 2019) [Artigo]
In cattle and other species, the fetal ovary is steroidogenically active before follicular development commences, and there is evidence that estradiol and progesterone inhibit follicle formation and activation. Estradiol ... -
Expression of fibroblast growth factor 22 (FGF22) and its receptor, FGFR1B, during development and regression of bovine corpus luteum
; Dalanezi, F. M.; Franchi, F. F. ; ; Ferreira, J. C. P. ; Trevisol, E. ; Buratini, J. (Theriogenology, 2019) [Artigo]
The aim of this study was to determine the expression of fibroblast growth factor 22 (FGF22) in the bovine corpus luteum (CL) and to investigate the effects of in vivo total or partial cloprostenol-induced luteolysis on ... -
Influence of diets supplemented with tryptophan on self-balancing, feed intake and productive performance in white cachama (Piaractus brachypomus)
Carolina Quintero-Pardo, Ana Maria; Giaquinto, Percilia Cardoso (Veterinaria Y Zootecnia, 2016) [Artigo]
This study evaluated the ability of juvenile white Pirapitinga to select food with different tryptophan content in order to self-balance the amino acid intake using information originated from the food source. Therefore, ... -
Influence of Tryptophan supplemented diets on self-balancing, food intake and growth performance of juvenile and adult Nile tilapia
Carolina Quintero-Pardo, Ana Maria; Giaquinto, Percilia Cardoso (Veterinaria Y Zootecnia, 2015) [Artigo]
This study aimed to test the effect of the ingestion of tryptophan on the self-balancing of the portion and the productive performance of Nile tilapia in the juvenile and adult stages. For this purpose, tryptophan supplemented ... -

Water jet: a simple method for classical conditioning in fish
Barretto, Adriana Beatriz; Maia, Caroline Marques ; Alves, Nina Pacheco Capelini ; Giaquinto, Percilia Cardoso (Acta Ethologica, 2018) [Artigo]
Classical conditioning in animals is a learning procedure involving a biologically relevant stimulus paired with a previously neutral stimulus. In fish, light and sound are frequently used as previously neutral stimuli for ... -
Individuality matters for substrate-size preference in the Nile tilapia juveniles
Maia, Caroline Marques; Volpato, Gilson Luiz (Journal of Applied Animal Welfare Science, 2018) [Artigo]
