The baroreflex in aquatic and amphibious teleosts: Does terrestriality represent a significant driving force for the evolution of a more effective baroreflex in vertebrates?
Armelin VA, Braga VHDS, Teixeira MT, Guagnoni IN, Wang T, Florindo LH. Armelin VA, et al. Comp Biochem Physiol A Mol Integr Physiol. 2021 May;255:110916. doi: 10.1016/j.cbpa.2021.110916. Epub 2021 Feb 2. Comp Biochem Physiol A Mol Integr Physiol. 2021. PMID: 33545361 Free article.
The baroreflex is a negative feedback loop, where altered P(A) results in reciprocal changes in heart rate (f(H)) and systemic vascular conductance to restore pressure. In terrestrial environments, gravity usually leads to blood pooling in the lower body reducing venous re …

The autonomic control of upright posture tachycardia in the arboreal lizard Iguana iguana.
Troiano NM, Armelin VA, Braga VHDS, Abe AS, Rantin FT, Florindo LH. Troiano NM, et al. J Exp Zool A Ecol Integr Physiol. 2018 Jul 10. doi: 10.1002/jez.2213. Online ahead of print. J Exp Zool A Ecol Integr Physiol. 2018. PMID: 29992754
Thus, our objective was to expand the knowledge on this issue by investigating it in an arboreal lizard (Iguana iguana). To do so, we analyzed f(H) , cardiac autonomic tones, and f(H) variability in horizontalized and tilted iguanas (0, 30. and 60) before and after …

Cardiorespiratory reflexes in white sturgeon (Acipenser transmontanus): Lack of cardiac baroreflex response to blood pressure manipulation?
Braga VHDS, Armelin VA, Noll IG, Florindo LH, Milsom WK. Braga VHDS, et al. Comp Biochem Physiol A Mol Integr Physiol. 2024 Feb;288:111554. doi: 10.1016/j.cbpa.2023.111554. Epub 2023 Nov 20. Comp Biochem Physiol A Mol Integr Physiol. 2024. PMID: 37989399
However, it is not clear whether more basal groups of vertebrates, such as cyclostomes, elasmobranchs and chondrosteans, manifest baroreflex regulation of f(H). Thus, the aim of this study was to determine whether the white sturgeon (Acipenser transmontanus; Chondrostei: A …

The Effects of Feeding on Cardiac Control of the Broad-Nosed Caiman (Caiman latirostris): The Role of the Autonomic Nervous System and NANC Factors.
Braga VH, Armelin VA, Teixeira MT, Abe AS, Rantin FT, Florindo LH. Braga VH, et al. J Exp Zool A Ecol Genet Physiol. 2016 Oct;325(8):524-531. doi: 10.1002/jez.2036. Epub 2016 Sep 21. J Exp Zool A Ecol Genet Physiol. 2016. PMID: 27650667
To this end, fasting and digesting animals were instrumented with intraperitoneal cannula and subcutaneous electrocardiogram electrodes (for the measurement of f(H) , cardiac autonomic tones, and total f(H) variability, as well as for a power spectral analysis of …
