Aims: As cardiac performance is closely related to its energy supply, our study investigated the effect of the orotic acid cardioprotective agent on the pathways of energy supply, in both conditions of normal flow and ischemia. Main methods: Male Wistar rats were fed during nine days with a balanced diet only or supplemented with 1% orotic acid. Key findings: Dietary administration of orotic acid increased the cardiac utilization of fatty acids, activity of the lipoprotein lipase, expression of the gene of peroxisome proliferator-activated receptor alpha and its target enzymes. In addition, orotic acid increased the myocardial uptake and incorporation of glucose, glycogen content and level of GLUT4, concentration of glycolytic metabolites and lactate production in both experimental conditions, baseline and after regional ischemia. Significance: Thus, in orotic acid hearts there was a simultaneous stimulus of fatty acid oxidation and glycolytic pathway, reflected in increased energetic content even in pre-ischemia. The analysis of the cardiac contractility index showed a positive inotropic effect of orotic acid due, at least in part, to the increased availability of energy. The result allows us to suggest that the metabolic changes induced by orotic acid result in appreciable alterations on myocardial contractile function. (C) 2012 Elsevier Inc. All rights reserved.

Dietary supplementation with Madagascar cockroach (Gromphadorhina portentosa) flour improves metabolic parameters reducing hepatic inflammatory markers in obese mice

J. R. Oliveira, J. M. O. Andrade, D. de F. Lelis, A. F. Paraiso, A. M. B. de Paula, A. L. S. Guimaraes, J. P. Lima, J. Cota, D. da Costa, S. H. S. Santos

Summary: The aim of this study was to evaluate the impact of Madagascar cockroach flour on body composition, biochemistry, and inflammation in the liver of obese mice. The results showed that the group treated with HFD-CF had lower levels of fasting glucose, total cholesterol, triglycerides, and pyruvic transaminase/aspartate aminotransferase compared to the HFD group. Additionally, the HFD+CF group exhibited reduced levels of liver interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) expression. These findings suggest that Madagascar cockroach flour may serve as a beneficial dietary supplement to improve biochemical and inflammatory alterations caused by obesity.

Apelin and Visfatin Expression in Placental Tissue in Women With Preeclampsia and Overweight/Obesity

Ana Paula dos Santos Xavier Braga, Diana Matos Silva, Deborah de Farias Lelis, Rogerio Estevam Farias, Alanna Fernandes Paraiso, Sergio Henrique Sousa Santos, Andrea Maria Eleuterio de Barros Lima Martins, Joao Marcus Oliveira Andrade

Summary: This study evaluated the expression levels of apelin and visfatin mRNA in placental tissue of women with preeclampsia and overweight/obesity and correlated it with maternal and fetal variables. The main findings showed lower levels of apelin expression in overweight/obese women, and a negative correlation with BMI and pre-pregnancy weight. Higher expression levels of apelin were observed in women with late PE and no personal history of PE. Higher visfatin expression levels were observed in women with late PE and term delivery, and a positive correlation was observed between visfatin levels and fetal anthropometric parameters.

Nutritional implications in the mechanistic link between the intestinal microbiome, renin-angiotensin system, and the development of obesity and metabolic syndrome

Victor Hugo Dantas Guimaraes, Barbhara Mota Marinho, Daisy Motta-Santos, Gabriela da Rocha Lemos Mendes, Sergio Henrique Sousa Santos

Summary: Obesity and metabolic disorders are significant global health problems, and the gut microbiota plays a crucial role in regulating systemic homeostasis. Recent evidence suggests that the microbiota and its signaling pathways can influence overall metabolism and the Renin-Angiotensin System (RAS), which, in turn, may impact the microbiota. This review aims to explore the nutritional implications in the mechanistic link between the intestinal microbiome, renin-angiotensin system, and the development of obesity and metabolic syndrome. It discusses the metabolic changes associated with obesity, diabetes, and hepatic steatosis based on relevant scientific literature, as well as the molecular and physiological mechanisms that affect the human microbiome. The review also analyzes the interaction and modulation of the RAS. Strategies such as the use of prebiotics, symbiotics, probiotics, and biotechnology may have an impact on gut microbiota and human health.

Brown adipose tissue transcriptome unveils an important role of the Beta-alanine/alamandine receptor, MrgD, in metabolism

Gabriela C. Cerri, Sergio H. S. Santos, Michael Bader, Robson A. S. Santos

Summary: Alamandine is a newly described component of the renin-angiotensin system (RAS) and its effects are mediated by the receptor Mas-related G protein-coupled receptor D (MrgD). This study aimed to assess the metabolic consequences of MrgD genetic ablation in mice by evaluating brown adipose tissue RNA sequencing. The results showed that MrgD-KO mice have diminished brown adipose tissue and a high-glucose diet decreased both circulating alamandine levels and MrgD expression in BAT from wild-type mice.

Metabolic and behavioral effects of time-restricted eating in women with overweight or obesity: Preliminary findings from a randomized study

Gabriela Barbosa Pires Fagundes, Jenneffer Rayane Braga Tibaes, Mariele Lino Silva, Marina Marcolino Braga, Ana Leticia Malheiros Silveira, Antonio Lucio Teixeira, Adaliene Versiani Matos Ferreira

Summary: The objective of this study was to evaluate the effects of 8 weeks of time-restricted eating (TRE) with a caloric restriction on metabolic profile, metabolic rate, symptoms of mood and eating disorders, and weight loss in women with overweight or obesity. The results showed that subjects in the TRE group experienced more pronounced weight loss, body fat mass loss, and fat-free mass loss compared to those in the non-TRE group. However, these losses were not associated with changes in resting metabolic rate, metabolic profile, or symptoms of eating or mood disorders. In conclusion, 8 weeks of TRE does not influence behavioral parameters in individuals with overweight or obesity, but may lead to weight loss.

Summary: This study aims to evaluate the effects of a high-refined carbohydrate (HC) diet on small intestine changes. Male BALB/c mice were fed an HC diet for 8 weeks, and it was found that although there were no significant differences in body weight gain, mice fed the HC diet exhibited adiposity and metabolic alterations. However, there were no significant changes observed in intestinal integrity, tight junction protein expression, intestinal permeability, and bacterial translocation.

Lychnophora ericoides Mart. (Brazilian arnica) ethanol extract accelerates the skin wound healing process: Evidence for its mechanism of action

Barbhara Mota Marinho, Victor Hugo Dantas Guimara, Daniel Silva Moraes, Guilherme Henrique Mendes Ribeiro, Rodrigo Moreira da Silva, Norberto Peporine Lopes, Andre Luiz Sena Guimara, Alfredo Mauricio Batista de Paula, Sergio Henrique Sousa Santos

Summary: The present study investigated the effects of Lychnophora ericoides ethanolic extract (EELE) on cutaneous wound healing and the underlying mechanisms. The results revealed that EELE significantly reduced the wound area, improved anatomical skin features, promoted collagen production and angiogenesis, and decreased the number of mast cells at the injury site. Real-time PCR data showed that EELE increased important factors for wound healing, such as FGF, VEGF, collagen formation, and the expression of the proliferative axis of the renin-angiotensin system.

Summary: Campomanesia guazumifolia, a plant from the Brazilian Cerrado, is used in traditional medicine for its medicinal properties. This study investigated the effects of the leaf infusion of Campomanesia guazumifolia on platelet activity, specifically focusing on the role of the cyclooxygenase (COX) pathway. The results showed that the infusion inhibits platelet aggregation and reduces intracellular calcium discharge, without involving the cyclic nucleotide pathways. Furthermore, the study identified that the infusion inhibits COX-1, reducing thromboxane A2 levels and PKCβ2 phosphorylation, suggesting its therapeutic potential for platelet-associated cardiovascular disease.
