Pharmacological Inhibition of Poly(ADP-Ribose) Polymerases Improves Fitness and Mitochondrial Function in Skeletal Muscle

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Evan Graehl Williams, Hongbo Zhang, Norman Lionel Moullan, Eija Riitta Pirinen, Keir Joe Menzies, Laia Morato Fornaguera, Wei Li

We previously demonstrated that the deletion of the poly(ADP-ribose) polymerase (Parp)-1 gene in mice enhances oxidative metabolism, thereby protecting against diet-induced obesity. However, the therapeutic use of PARP inhibitors to enhance mitochondrial f ...

Pathophysiological role of the renin-angiotensin system on erectile dysfunction

Nikolaos Stergiopoulos

Background The renin-angiotensin system (RAS) has been shown to play an active role within the erectile tissues. The aim of this narrative review is to summarize the literature addressing the pathophysiological role of RAS on erectile function. Additionall ...

An Oral Formulation of Angiotensin-(1-7) Reverses Corpus Cavernosum Damages Induced by Hypercholesterolemia

Nikolaos Stergiopoulos, Fabiana Pereira Da Costa Fraga, Danielle Gomes Passos Silva

Introduction The renin angiotensin system plays a crucial role in erectile function. It has been shown that elevated angiotensin-II levels contribute to the development of erectile dysfunction (ED). Oppositely, angiotensin-(1-7) (Ang-[1-7]) mediates penile ...

Treatment with CB2 Agonist JWH-133 Reduces Histological Features Associated with Erectile Dysfunction in Hypercholesterolemic Mice

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Younouss Faye

Hypercholesterolemia is one of the most important risk factors for erectile dysfunction, mostly due to the impairment of oxidative stress and endothelial function in the penis. The cannabinoid system might regulate peripheral mechanisms of sexual function; ...

Increase of arginase activity in old apolipoprotein-E deficient mice under Western diet associated with changes in neurovascular unit

Rafaela Fernandes Da Silva, Jean-Christophe Copin

Aging and atherosclerosis are well-recognized risk factors for cardiac and neurovascular diseases. The Apolipoprotein E deficient (ApoE-/-) mouse on a high-fat diet is a classical model of atherosclerosis, characterized by the presence of atherosclerotic p ...

Reduced cyclic stretch, endothelial dysfunction, and oxidative stress: an ex vivo model

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Paolo Silacci, Tyler Nerton Thacher, Veronica Gambillara

The objective of this study was to investigate whether reduction of cyclic circumferential stretch will impair endothelial function and elevate basal levels of oxidative stress, both known risk factors linked to cardiovascular disease. ...

Hybrid Ultrasonic Motor and Electrorheological Clutch System for MR-Compatible Haptic Rendering

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet

Using haptic interfaces in combination with functional magnetic resonance imaging (fMRI) could lead to important insights into the brain mechanisms of human motor control and related dysfunctions. However, in addition to the usual requirements for haptic i ...

First in vivo MRI assessment of a self-assembled metallostar compound endowed with a remarkable high field relaxivity

André Merbach, Lothar Helm, Eva Jakab Toth, Joao Bruno Livramento Fig.

{Fe[Gd2bpy(DTTA)2(H2O)4]3}4- is a self-assembled, metallostar-structured potential MRI contrast agent, with six efficiently relaxing Gd3+ centers confined into a small mol. space. Its proton relaxivity is particularly remarkable at very high magnetic field ...

Multi-Joint Arm Movements to Investigate Motor Control with fMRI

Hannes Bleuler, Roger Gassert, Etienne Burdet, Ludovic Dovat

Performing multi-joint arm movements in controllable dynamic environments during functional magnetic resonance imaging (fMRI) could provide important insights into the brain mechanisms involved in human motor control and related dysfunctions. In order to o ...
