0347: Beneficial cardiovascular effects of O-GlcNAc stimulation in early phase of septic shock
2016
BackgroundO-GlcNAcylation, a post-translational modification, is the end product of the hexosamine biosynthetic pathway (HBP). Recent studies showed beneficial effects of its increase in acute pathologies, such as hemorrhagic shock. We postulated that increase in total protein OGlcNAcylation at the early phase of septic shock, a systemic inflammation associated with a cardiovascular dysfunction, could improve cardiovascular function and reduce mortality.MethodsTo induce an endotoxemic shock, rats (n=6-8) received iv either lipopolysaccharide (LPS, 5mg/kg) or saline (CTRL). After 1 h, fluid resuscitation (FR,15mL/kg of colloid, iv) was associated or not with HBP substrate: glucosamine (GlcN,…
Chronic consumption of an inositol-enriched beverage ameliorates endothelial dysfunction and oxidative stress in type 2 diabetes
2015
The anti-diabetic properties of an inositol-enriched beverage (IEB) on the endothelial function and redox status in diabetic subjects were assessed. This was a 12-week, double-blind randomized controlled trial employing thirty-eight diabetic subjects that were divided into two intervention groups: one receiving an IEB and the other a sucrose-enriched beverage. Subjects consuming IEB exhibited a significant decrease in triacylglycerol (8.82%) and HbA1c (4.53%) levels. Continuous glucose monitoring revealed a significant net reduction of 2.51 and 7.11% during postprandial and overnight fasting periods after consumption of IEB, respectively. Moreover, IEB improved endothelial function by reduc…
Postprandial metabolism: from research to clinical practice.
2013
Over the last decade, the importance of postprandial metabolism has increased, given that it is the physiological state of humans in modern society. Moreover, postprandial lipemia is considered as a key player in the development of the most important cardiometabolic diseases. In this regard, postprandial lipemia has become more important, since it has been demonstrated that nonfasting triglycerides (TGs) are independent predictors of the risk of cardio vascular disease (CVD) [1,2]. Interestingly, the postprandial phase has been associated with increased inflammation and oxidation, which influences vascular function through a permanent endothelial aggression by atherogenic lipoprotein. TGs a…
A review of recent evidence in human studies of n-3 and n-6 PUFA intake on cardiovascular disease, cancer, and depressive disorders: does the ratio r…
2015
AbstractPolyunsaturated fatty acids (PUFAs) have been considered of great interest for human health due to their potential anti-inflammatory action that may protect from a number of chronic-degenerative diseases with an inflammatory pathogenesis. This review aimed to report the most updated evidence of both n-3 and n-6 PUFAs effect on cardiovascular disease, cancer, and depression in humans. Attention has been also paid to those studies exploring the effects of the ratio intake. Results from pooled analyses of human studies reported a general positive effect of n-3 PUFAs intake on all outcomes considered. In contrast, the role of n-6 PUFAs on human health needs to be better assessed in orde…
Peripheral amplification of sweating - a role for calcitonin gene-related peptide
2006
Neuropeptides are the mediators of neurogenic inflammation. Some pain disorders, e.g. complex regional pain syndromes, are characterized by increased neurogenic inflammation and by exaggerated sudomotor function. The aim of this study was to explore whether neuropeptides have a peripheral effect on human sweating. We investigated the effects of different concentrations of calcitonin gene-related peptide (CGRP), vasoactive intestinal peptide (VIP) and substance P (SP) on acetylcholine-induced axon reflex sweating in healthy subjects (total n = 18). All substances were applied via dermal microdialysis. The experiments were done in a parallel setting: ACh alone and ACh combined with CGRP, VIP …
COVID-19 and Alzheimer’s Disease
2021
The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a neurotropic virus with a high neuroinvasive potential. Indeed, more than one-third of patients develop neurological symptoms, including confusion, headache, and hypogeusia/ageusia. However, long-term neurological consequences have received little interest compared to respiratory, cardiovascular, and renal manifestations. Several mechanisms have been proposed to explain the potential SARS-CoV-2 neurological injury that could lead to the development of neurodegenerative diseases, including Alzheimer’s Disease (AD). A mutualistic relationship between AD and COVID-19 seems to exist. On the one hand, COVID-19 patients seem to …
Substance P Serum Degradation in Complex Regional Pain Syndrome – Another Piece of the Puzzle?
2021
In a previous study, we demonstrated that the serum peptidase system might be less efficient in complex regional pain syndrome (CRPS). Since the neuropeptide substanc P (SP) contributes to inflammation in CRPS, we now investigated the metabolism of SP in CRPS specifically. An SP metabolism assay was performed in 24 CRPS patients, which constitute a subgroup of our previous investigation on BK degradation. In addition, we included 26 healthy controls (24 newly recruited plus 2 from our previous investigation), and 13 patients after limb trauma, who did not fulfil the CRPS diagnostic criteria (trauma controls, TC) were included. We adapted a thin layer chromatography assay (TLC) to quantify S…

eNOS Uncoupling in Cardiovascular Diseases - the Role of Oxidative Stress and Inflammation
2013
Many cardiovascular diseases and drug-induced complications are associated with - or even based on - an imbalance between the formation of reactive oxygen and nitrogen species (RONS) and antioxidant enzymes catalyzing the break-down of these harmful oxidants. According to the “kindling radical” hypothesis, the formation of RONS may trigger in certain conditions the activation of additional sources of RONS. According to recent reports, vascular dysfunction in general and cardiovascular complications such as hypertension, atherosclerosis and coronary artery diseases may be connected to inflammatory processes. The present review is focusing on the uncoupling of endothelial nitric oxide synthas…
