Two-year-old girl with tuberous xanthomas.
2018
A 2-year-old girl was referred for evaluation because she had two nodular lesions located on both heels, and another elongated lesion in the intergluteal cleft. On physical examination, two yellow to orange well-defined nodules, suggestive of xanthomas, were bilaterally located on the Achilles tendon areas (figure 1A). Moreover, another yellowish, slightly raised lesion with band-like morphology was seen in the intergluteal cleft (figure 1B). There were no other anomalies on physical examination. Figure 1 (A) Tuberous xanthoma located on the left heel. (B) Planar xanthoma located in the intergluteal cleft. (C) Peripheral blood smear examination showing numerous red cells and two macrothromb…
Contribution of cholesterol and oxysterols to the pathophysiology of Parkinson's disease
2016
International audience; Neurodegenerative diseases are a major public health issue worldwide. Some countries, including France, have engaged in research into the causes of Parkinson's disease, Alzheimer's disease, and multiple sclerosis and the management of these patients. It should lead to a better understanding of the mechanisms leading to these diseases including the possible involvement of lipids in their pathogenesis. Parkinson's disease is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra and the accumulation of α-synuclein (Lewy bodies). Several in vivo studies have shown a relationship between the lipid profile [chole…
PPAR Agonists, Atherogenic Dyslipidemia and Cardiovascular Risk.
2016
Peroxisome proliferator-activated receptors (PPAR) are implicated in the pathology of several metabolic diseases including obesity, diabetes, and atherosclerosis. PPAR agonists exert multiple lipid modifying actions which are beneficial to the prevention of atherosclerosis. Such benefits in lipid lowering actions include improvements in atherogenic dyslipidemia that seems to be particularly expressed in individuals at higher cardiovascular (CV) risk. In addition, the favorable effects of PPAR agonists on different cardio-metabolic parameters are established in several metabolic conditions, such as diabetes mellitus, insulin resistance, and heightened systemic inflammation. The goal of this …
Detection of Vasodilators From Herbal Components by a Transcriptome-Based Functional Gene Module Reference Approach
2019
Vasodilatation is one of the key therapeutic strategies for the treatment of various cardiovascular diseases with high blood pressure. Therefore, development of drugs assisting blood vessel dilation is promising. It has been proved that many drugs display definite vasorelaxant effects. However, there are very few studies that systemically explore the effective vasodilators. In this work, we build a transcriptome-based functional gene module reference approach for systematic pursuit of agents with vasorelaxant effects. We firstly curate two functional gene modules that specifically involved in positive and negative regulation of vascular diameter based on the known gene functional interactio…
Polyphenol intake from a Mediterranean diet decreases inflammatory biomarkers related to atherosclerosis: a substudy of the PREDIMED trial
2016
High dietary polyphenol intake is associated with reduced all-cause mortality and a lower incidence of cardiovascular events. However, the mechanisms involved are not fully understood. The aim of the present substudy of the PREvencion con DIetaMEDiterranea (Prevention with Mediterranean diet; PREDIMED) trial was to analyse the relationship between polyphenol intake measured by total urinary polyphenol excretion (TPE), and circulating inflammatory biomarkers and cardiovascular risk factors in elderly individuals. A substudy of 1139 high-risk participants was carried out within the PREDIMED trial. The subjects were randomly assigned to a low-fat control diet or to two Mediterranean diets, sup…
The Novel Oral Anticoagulants for Acute Venous Thromboembolism: Is Warfarin Dead?
2017
The direct oral anticoagulants (DOACs) have been compared with parenteral anticoagulants and vitamin K antagonists (VKAs) for the treatment of venous thromboembolism (VTE) in several robust studies. DOACs have shown similar efficacy in preventing recurrent VTE and significant reductions in critical site (intracranial) bleeding, fatal bleeding, major and nonmajor bleeding. Warfarin and other VKAs are not dead as treatment modalities for VTE. A better way to describe the current situation is to use a boxing expression, “down but not out.” VKAs and parenteral anticoagulants still have a role to play in the management of VTE in several clinical settings. In indications where DOACs can be used, …
Gene expression changes after parental exposure to metals in the sea urchin affect timing of genetic programme of embryo development
2021
Simple Summary Intergenerational and transgenerational effects, in which exposure to stressors in a parental generation affects the phenotype of the offspring have been connected to anthropic impacts on biological systems. Therefore, environmental stress experienced inside a generation, particularly during gametogenesis, may lead to erroneous patterns in their offspring just emerging at early developmental stages. In this scenario, the sea urchin embryo represents a suitable model for integrating analyses of gene expression through embryogenesis with developmental alteration induced by environmental stressors. Herein we provide pieces of evidence for the alteration of the gene regulatory ne…
Anti-PCSK9 treatment: is ultra-low low-density lipoprotein cholesterol always good?
2018
Anti-PCSK9 (proprotein convertase subtilisin kexin 9) monoclonal antibodies (Mab) are novel, potent lipid-lowering drugs. They demonstrated to improve the lipid profile in high cardiovascular risk patients. Anti-PCSK9 Mab inhibit the targeted low-density lipoprotein (LDL)-receptor degradation induced by PCSK9 protein and are able to reduce LDL cholesterol (LDL-C) levels on top of conventional lipid-lowering therapy. Though these drugs proved to be very safe in the short-term, little is known about the possible long-term effects, due to the short period of their marketing. The genetic low cholesterol syndromes (LCS) represent the natural models of the lipid-lowering anti-PCSK9 therapy, and a…
Moderate Red Wine Consumption Increases the Expression of Longevity-Associated Genes in Controlled Human Populations and Extends Lifespan in Drosophi…
2021
The beneficial effects of moderate red wine consumption on cardiovascular health are well known. The composition of red wine includes several compounds, such as the phytoestrogen resveratrol, that exert these beneficial effects, although not all the mechanisms by which they act are known. Our aim was to study the effect of red wine consumption on longevity-related genes in controlled human populations, such as cloistered nuns. We found that the expression of catalase, manganese-superoxide dismutase, Sirt1, and p53 was increased in peripheral blood mononuclear cells after 14 days of moderate red wine consumption. This increase was accompanied by an enhanced metabolic wellness: fatty acids, c…
