New insights on amygdala : basomedial amygdala regulates the physiological resp...
Mesquita, Laura Batista Tavares; Abreu, Aline Rezende Ribeiro de; Abreu, Alessandra Rezende Ribeiro de; Souza, Aline Maria Arlindo deThe amygdala has been associated with a variety of functions linked to physiological, behavioral and endocrine responses during emotional situations. This brain region is comprised of multiple sub-nuclei. These subnuclei belong to the same structure, but may be involved in different functions, thereby making the study of each sub-nuclei important. Yet, the involvement of the basomedial amygdala (BMA) in the reg...
Chronic treatment with ivabradine does not affect cardiovascular autonomic cont...
Silva, Fernanda Cacilda dos Santos; Paiva, Franciny Aparecida; Ribeiro, Flavia Camargos de Figueiredo Müller; Caldeira, Henrique Martins ArantesA low resting heart rate (HR) would be of great benefit in cardiovascular diseases. Ivabradine-a novel selective inhibitor of hyperpolarization-activated cyclic nucleotide gated (HCN) channels- has emerged as a promising HR lowering drug. Its effects on the autonomic HR control are little known. This study assessed the effects of chronic treatment with ivabradine on the modulatory, reflex and tonic cardiovascul...
Tobacco-free cigarette smoke exposure induces anxiety and panic-related behavio...
Chírico, Máira Tereza Talma; Bezerra, Frank Silva; Guedes, Mariana Reis; Souza, Ana Beatriz Farias de; Silva, Fernanda Cacilda dos SantosSmokers, who generally present with lung damage, are more anxious than non-smokers and have an associated augmented risk of panic. Considering that lung damage signals specific neural pathways that are related to affective responses, the aim of the present study was to evaluate the influence of pulmonary injury on anxiety and panic-like behaviours in animals exposed to cigarette smoke with and without tobacco. ...
Nitric oxide modulates blood pressure through NMDA receptors in the rostral ven...
Machado, Natália Lima Santos; Silva, Fernanda Cacilda dos Santos; Chianca Júnior, Deoclécio Alves; Menezes, Rodrigo Cunha Alvim deThe rostral ventrolateral medulla (RVLM) is an important site of cardiovascular control related to the tonic excitation and regulating the sympathetic vasomotor tone through local presympathetic neurons. Nitric oxide (NO) has been implicated in the modulation of neurotransmission by several areas of the central nervous system including the RVLM. However the path ways driving NO affects and the correlation betwe...
The role of dorsomedial hypotalamus ionotropic glutamate receptors in the hyper...
Silva, Fernanda Cacilda dos Santos; Guidine, Patrícia Alves Maia; Machado, Natália Lima Santos; Xavier, Carlos Henrique; Menezes, Rodrigo Cunha Alvim deThe scorpion envenoming syndrome is an important worldwide public health problem due to its high incidence and potential severity of symptoms. Some studies address the high sensitivity of the central nervous system to this toxin action. It is known that cardiorespiratory manifestations involve the activation of the autonomic nervous system. However, the origin of this modulation remains unclear. Considering the...
What is the role of inflammatory mediators on energy metabolism?
Gomes, Simone Fátima; Silva, Fernanda Cacilda dos Santos; Volp, Ana Carolina PinheiroThe subclinical and low intensity inflammation, oxidative stress, high calorie and high fat diet patterns are striking features of the obesity. The adipose tissue, through its endocrine function, is associated with the cytokines secretion, such as: IL-4, IL-13, IL-15 and IFN-γ, which trigger metabolic changes and possibly modulate the energy metabolism by modifying the biochemical, anthropometric and body compo...
Prospects about the use of Açaí (Euterpe oleracea Mart.) on the Modulation of t...
Gomes, Simone Fátima; Silva, Fernanda Cacilda dos Santos; Volp, Ana Carolina PinheiroThe adiposity excess has as consequences metabolic complications which could predispose to the onset of chronic diseases concomitantly to induction of an inflammatory condition of low intensity by means of the secretion and expression of inflammatory cytokines in adipose tissue. These cytokines (IL-2, IL-4, IL-13, IL-15 e IFN-γ) may be involved in the regulation of energetic metabolism and food intake, contribu...
Acceptance of handmade products containing nuts and fructooligosaccharides.
Folly, Gilce Andrezza de Freitas; Silva, Ester Neiva da; Verner, Fabiana Vieira; Silva, Fernanda Cacilda dos Santos; Volp, Ana Carolina PinheiroIntroduction: Prebiotic and food with functional properties are beneficial for consumers through prevention of many diseases. Aim: Verify the acceptance of handmade product (chocolate bar, soy sweet and sweet bread) formulated based on oil seeds (flaxseed, peanut and Brazil nut) and or fructooligosaccharides (FOS). Methods: Four samples of each handmade product were prepared adding different concentrations of o...
Hepatic inflammatory biomarkers and its link with obesity and chronic diseases.
Volp, Ana Carolina Pinheiro; Silva, Fernanda Cacilda dos Santos; Bressan, JosefinaIntroduction: The low-grade inflammation and insulin resistance are two events that could be present in varying degrees, on obesity and chronic diseases. The degree of subclinical inflammation can be gauged by measuring the concentrations of some inflammatory biomarkers, including the hepatic origin ones. Some of those biomarkers are sialic acid, 1-antitrypsin and the C-terminal fragment of alpha1-antitrypsin,...
