Cutaneous TRPV4 Channels Activate Warmth-Defense Responses in Young and Adult Birds
(Frontiers in Physiology, 2022) [Artigo]Transient receptor potential vanilloid 4 (TRPV4) channels are sensitive to warm ambient temperatures (Tas), triggering heat loss responses in adult rats in a Tas range of ∼26–30°C. In birds, however, the thermoregulatory ... -
Predicting maximal lactate steady state from lactate thresholds determined using methods based on an incremental exercise test in beagle dogs: A study using univariate and multivariate approaches
(Research in Veterinary Science, 2022) [Artigo]The reliability of four lactate threshold (LT) methods to estimate the maximal lactate steady state (MLSS), defined as the highest intensity that can be maintained without plasma lactate ([La−]) accumulation over time, was ... -
Melanin-concentrating hormone regulates the hypercapnic chemoreflex by acting in the lateral hypothalamic area
(Experimental Physiology, 2022) [Artigo]New Findings: What is the central question of this study? Melanin-concentrating hormone (MCH) suppresses the hypercapnic chemoreflex: what is the mechanism by which this effect is produced? What is the main finding and its ... -
Control of Breathing in Ectothermic Vertebrates
(Comprehensive Physiology, 2022) [Artigo]The ectothermic vertebrates are a diverse group that includes the Fishes (Agnatha, Chondrichthyes, and Osteichthyes), and the stem Tetrapods (Amphibians and Reptiles). From an evolutionary perspective, it is within this ... -
Prenatal fluoxetine has long-lasting, differential effects on respiratory control in male and female rats
(Journal of applied physiology (Bethesda, Md. : 1985), 2022) [Artigo]Serotonin (5-HT) is an important modulator of brain networks that control breathing. The selective serotonin reuptake inhibitor fluoxetine (FLX) is the first-line antidepressant drug prescribed during pregnancy. We ... -
Temporal and spatial diversification along the Amazonia-Cerrado transition in Neotropical treefrogs of the Boana albopunctata species group
(Molecular Phylogenetics and Evolution, 2022) [Artigo]Despite extensive research on biodiversity in Neotropical forests, biodiversity in seasonally dry, open biomes in South America has been underestimated until recently. We leverage a widespread group, Boana albopunctata, ... -
Sexually dimorphic effects of prenatal diazepam exposure on respiratory control and the monoaminergic system of neonate and young rats
(Pflugers Archiv European Journal of Physiology, 2022) [Artigo]Pregnancy is highly affected by anxiety disorders, which may be treated with benzodiazepines, especially diazepam (DZP), that can cross the placental barrier and interact with the fetal GABAergic system. We tested whether ... -
Checklist of decapod crustaceans from the coast of the So Paulo state (Brazil) supported by integrative molecular and morphological data: V. Dendrobranchiata and Pleocyemata [Achelata, Astacidea, Axiidea, Caridea (Alpheoidea and Processoidea excluded), Gebiidea, Stenopodidea
(Zootaxa, 2022) [Artigo]This checklist is the fifth and last compilation on the decapod crustaceans reported to So Paulo (Brazil) coastal area, resulting from long-term multidisciplinary projects, which combined morphological analyses and molecular ... -
Cuticular hydrocarbons as caste-linked cues in Neotropical swarm-founding wasps
(PeerJ, 2022) [Artigo]Wasps (Vespidae) are important organisms to understand the evolution of socia behaviour. Wasps show different levels of sociality, which includes solitary to highly eusocial organisms. In social insect species, queens and ... -
Association between vitamin D and malignant mammary tumors in obese female dogs
(Brazilian Journal of Veterinary Pathology, 2022) [Artigo]Overweight and obesity are known risk factors that are involved in the development and aggressiveness of breast tumors in women. In situations of obesity, local and systemic inflammation may worsen the prognosis of oncological ... -
CO2 exposure enhances Fos expression in hypothalamic neurons in rats during the light and dark phases of the diurnal cycle
(Brain Structure & Function, 2022) [Artigo]Orexinergic (OX) neurons in the lateral hypothalamus (LH), perifornical area (PFA) and dorsomedial hypothalamus (DMH) play a role in the hypercapnic ventilatory response, presumably through direct inputs to central pattern ... -
Effect of In Ovo Ascorbic Acid Injection and Thermal Manipulation During Incubation on Intestine Morphology of Broilers Reared under Cold and Heat Stress
(Brazilian Journal Of Poultry Science, 2022) [Artigo]It was investigated if pre-incubation ascorbic acid (AA) injection in fertile eggs incubated at high temperature impacts the performance, the yield of carcass and parts, and the intestine morphology of broilers reared under ... -
The courtship call of Bokermannohyla ibitiguara (Anura: Hylidae) and details of its mating behavior
(Caldasia, 2022) [Artigo]Complex courtships have been described for neotropical frogs, but detailed quantifications of calls emitted during this behavior are still rare. Herein, we describe the courtship call of Bokermannohyla ibitiguara, a gladiator ... -
Vacuum packaged embalmed dogs for veterinary surgery practicing
(European Journal Of Anatomy, 2021) [Artigo]It is imperative to have a lot of discretion regarding animals' use in research and teaching activities. Consequently, the search for alternative methods that do not cause academic or scientific damage is essential. This ... -
