Cerebro- and cardio-vascular responses to energy drink in young adults: Is there a gender effect?

Monnard, Cathríona R. ; Montani, Jean-Pierre ; Grasser, Erik K.

In: Integrative Physiology, 2016, p. 346

Background and Purpose: Energy drinks (EDs) are suspected to induce potential adverse cardiovascular effects and have recently been shown to reduce cerebral blood flow velocity (CBFV) in young, healthy subjects. Gender differences in CBFV in response to EDs have not previously been investigated, despite the fact that women are more prone to cardiovascular disturbances such as...

Uninephrectomy-induced lipolysis and low-grade inflammation are mimicked by unilateral renal denervation

Arsenijevic, Denis ; Cajot, Jean-François ; Fellay, Benoit ; Dulloo, Abdul G. ; Vliet, Bruce N. Van ; Montani, Jean-Pierre

In: Integrative Physiology, 2016, p. 227

Uninephrectomy (UniNX) in rats on a fixed food intake leads to increased lipolysis and a low-grade inflammation with an increased subset of circulating cytokines. Because UniNX ablates renal nerves on the side of the removed kidney, we tested the contribution of unilateral renal denervation in the phenotype of UniNX. We compared Sham-operated controls, left nephrectomy (UniNX) and unilateral...

"En Face" detection of nitric oxide and superoxide in endothelial layer of intact arteries

Yu, Yi ; Xiong, Yuyan ; Montani, Jean-Pierre ; Yang, Zhihong ; Ming, Xiu-Fen

In: Journal of Visualized Experiments, 2016, no. 108, p. -

Endothelium-derived nitric oxide (NO) produced from endothelial NO-synthase (eNOS) is one of the most important vasoprotective molecules in cardiovascular physiology. Dysfunctional eNOS such as uncoupling of eNOS leads to decrease in NO bioavailability and increase in superoxide anion (O₂.−) production, and in turn promotes cardiovascular diseases. Therefore, appropriate...

Energy expenditure and substrate oxidation in response to side-alternating whole body vibration across three commonly-used vibration frequencies

Fares, Elie-Jacques ; Charrière, Nathalie ; Montani, Jean-Pierre ; Schutz, Yves ; Dulloo, Abdul G. ; Miles-Chan, Jennifer L.

In: PLOS ONE, 2016, vol. 11, no. 3, p. e0151552

There is increasing recognition about the importance of enhancing energy expenditure (EE) for weight control through increases in low-intensity physical activities comparable with daily life (1.5–4 METS). Whole-body vibration (WBV) increases EE modestly and could present both a useful adjuvant for obesity management and tool for metabolic phenotyping. However, it is unclear whether a...

Targeting arginase-II protects mice from high-fat-diet-induced hepatic steatosis through suppression of macrophage inflammation

Liu, Chang ; Rajapakse, Angana G. ; Riedo, Erwin ; Fellay, Benoit ; Bernhard, Marie-Claire ; Montani, Jean-Pierre ; Yang, Zhihong ; Ming, Xiu-Fen

In: Scientific Reports, 2016, vol. 6, p. 20405

Nonalcoholic fatty liver disease (NAFLD) associates with obesity and type 2 diabetes. Hypoactive AMP-activated protein kinase (AMPK), hyperactive mammalian target of rapamycin (mTOR) signaling, and macrophage-mediated inflammation are mechanistically linked to NAFLD. Studies investigating roles of arginase particularly the extrahepatic isoform arginase-II (Arg-II) in...

Uninephrectomy in rats on a fixed food intake potentiates both anorexia and circulating cytokine subsets in response to LPS

Arsenijevic, Denis ; Montani, Jean-Pierre

In: Frontiers in Immunology - Inflammation, 2015, p. 641

Recent human studies have suggested that mild reduction in kidney function can alter immune response and increase susceptibility to infection. The role of mild reduction in kidney function in altering susceptibility to bacterial lipopolysaccharide (LPS) responses was investigated in uninephrectomized rats compared to Sham-operated controls rats 4 weeks after surgery. Throughout the 4 weeks, all...

Postprandial hypotension in older adults: Can it be prevented by drinking water before the meal?

Grobéty, Bastien ; Grasser, Erik Konrad ; Yepuri, Gayathri ; Dulloo, Abdul G. ; Montani, Jean-Pierre

In: Clinical Nutrition, 2015, vol. 34, no. 5, p. 885–891

Background & aimsAn important consequence of ageing is a tendency for postprandial blood pressure to decline, which can lead to fainting. As a possible countermeasure, we investigated in healthy older adults the impact of drinking water before a breakfast meal on postprandial cardiovascular and autonomic functions.MethodsAfter a stable cardiovascular baseline recording for at least 20 min,...

Pathways from dieting to weight regain, to obesity and to the metabolic syndrome: an overview

Dulloo, Abdul G. ; Montani, Jean-Pierre

In: Obesity Reviews, 2015, vol. 16, p. 1–6

Every year, scores of millions of people – as diverse as obese and lean, teenagers and older adults, sedentary and elite athletes, commoners and celebrities – attempt to lose weight on some form of diet. They are often encouraged by their parents, friends, health professionals, training coaches, a media that promotes a slim image and a diet- industry that in Europe and United States alone...

The thermic effect of sugar-free Red Bull: Do the non-caffeine bioactive ingredients in energy drinks play a role?

Miles-Chan, Jennifer L. ; Charrière, Nathalie ; Grasser, Erik K ; Montani, Jean-Pierre ; Dulloo, Abdul G.

In: Obesity, 2015, vol. 23, no. 1, p. 16–19

Objective: Consumption of energy drinks is increasing amongst athletes and the general public. By virtue of their bioactive ingredients (including caffeine, taurine, glucuronolactone, and B-group vitamins) and paucity of calories, sugar-free “diet” versions of these drinks could be a useful aid for weight maintenance. Yet little is known about the acute influence of these drinks, and...

How dieting makes the lean fatter: from a perspective of body composition autoregulation through adipostats and proteinstats awaiting discovery

Dulloo, Abdul G. ; Jacquet, Jean ; Montani, Jean-Pierre ; Schutz, Yves

In: Obesity Reviews, 2015, vol. 16, p. 25–35

Whether dieting makes people fatter has been a subject of considerable controversy over the past 30 years. More recent analysis of several prospective studies suggest, however, that it is dieting to lose weight in people who are in the healthy normal range of body weight, rather than in those who are overweight or obese, that most strongly and consistently predict future weight gain. This paper...
