Study of leurocyte telomere lenght and transcription in patients in the acute phase of myocardial infarction

2011

Atherosclerosis with cardiovascular complications remains today one of the leading causes of death in developed countries. In this context, development of new biomarkers of atherosclerosis has an important place. Objectives of these biomarkers are: • to identify populations most at risk of developing cardiovascular complications, • to stratify patient groups to optimize their clinical management and therapeutic, • to reveal new therapeutic targets in the treatment of the disease. In this context, we identified three biomarkers of interest, leukocyte telomere length (LTL) and level of expression of leukocyte genes c-Fos (involved in inflammatory processes and oxidative) and OGG1 (necessary r…

Therapeutic implications of targeting antioxidants to mitochondria

2021

Abstract Redox and oxidative balance are mainly regulated by mitochondria, which control the life and death of cells and organisms, and are therefore implicated in multiple pathologies. Mitochondria can be considered key organelles to be used in different therapeutically approaches, and mitochondria-targeted antioxidants have already shown great potential in the treatment of various human diseases. In fact, major progress has been achieved in the development of different molecules targeted to mitochondria. In this chapter, we will discuss the various strategies that have been employed, such as molecules conjugated with lipophilic cations (e.g., triphenylphosphonium) and peptide-based compou…

Hysteroscopic Evaluation of Endometrial Changes in Breast Cancer Women with or without Hormone Therapies: Results from a Large Multicenter Cohort Stu…

2020

ABSTRACT Study Objective The primary aim of our study was to investigate the incidence of endometrial pathologies, especially endometrial cancer, in women with breast cancer treated with tamoxifen (TAM), aromatase inhibitors (AIs), or receiving no treatment (NT). The secondary aim was to identify, in this cohort, ultrasonographic findings that represent robust indications for hysteroscopy and endometrial biopsy, to avoid unnecessary second-level diagnostic procedures. Design Multicenter retrospective cohort study (Clinical Trial ID: NCT03898947). Setting Data were collected from different Italian centers: Regina Elena National Cancer Institute of Rome, Arbor Vitae Centre of Rome, Gaetano Ma…

Argumentation graphs with constraint-based reasoning for collaborative expertise

2018

International audience; Collaborative processes are very important in telemedicine domain since they allow for making right decisions in complex situations with multidisciplinary staff. When modelling these collaborative processes, some inconsistencies can appear. In semantic modelling (conceptual graphs), these inconsistencies are verified using constraints. In this work, collaborative processes are represented using an argumentation system modelled in a conceptual graph formalism where inconsistencies could be particular bad attack relation between arguments. To overcome these inconsistencies, two solutions are proposed. The first one is to weight the arguments evolving in the argumentati…

Safety and Pharmacokinetics of Glecaprevir/Pibrentasvir in Adults With Chronic Genotype 1–6 Hepatitis C Virus Infections and Compensated Liver Disease

2019

Background: Untreated, chronic hepatitis C virus (HCV) infection may lead to progressive liver damage, which can be mitigated by successful treatment. This integrated analysis reports the safety, efficacy, and pharmacokinetics (PK) of the ribavirin-free, direct-acting, antiviral, fixed-dose combination of glecaprevir/pibrentasvir (G/P) in patients with chronic HCV genotype 1-6 infections and compensated liver disease, including patients with chronic kidney disease stages 4 or 5 (CKD 4/5). Methods: Data from 9 Phase II and III clinical trials, assessing the efficacy and safety of G/P treatment for 8-16 weeks, were included. The presence of cirrhosis was determined at screening using a liver …

Adverse drug reactions in some African herbal medicine: literature review and stakeholders’ interview

2014

International audience; Background: In view of the large consumption of herbal medicine in Africa countries, it is likely that many adverse drugs reactions go unrecorded with either patients failing to present to health services, or no pharmacovigilance analysis being made, or the analysis not being reported centrally. This problem is of interest especially for those who are working in the general area of adverse drug reactions or stakeholders in the domain of herbal medicine for considering safety issues. Methods: We are particularly interested in the way that the use of very wellknown and highly valued plants is linked to the observation of adverse drug reactions in African countries. We …

Lipid chaperones and associated diseases: a group of chaperonopathies defining a new nosological entity with implications for medical research and pr…

2020

AbstractFatty acid–binding proteins (FABPs) are lipid chaperones assisting in the trafficking of long-chain fatty acids with functions in various cell compartments, including oxidation, signaling, gene-transcription regulation, and storage. The various known FABP isoforms display distinctive tissue distribution, but some are active in more than one tissue. Quantitative and/or qualitative changes of FABPs are associated with pathological conditions. Increased circulating levels of FABPs are biomarkers of disorders such as obesity, insulin resistance, cardiovascular disease, and cancer. Deregulated expression and malfunction of FABPs can result from genetic alterations or posttranslational mo…

A Major Effect Gene Controlling Development and Pathogenicity in Botrytis cinerea Identified Through Genetic Analysis of Natural Mycelial Non-pathoge…

2021

Botrytis cinerea is a necrotrophic plant pathogenic fungus with a wide host range. Its natural populations are phenotypically and genetically very diverse. A survey of B. cinerea isolates causing gray mold in the vineyards of Castilla y León, Spain, was carried out and as a result eight non-pathogenic natural variants were identified. Phenotypically these isolates belong to two groups. The first group consists of seven isolates displaying a characteristic mycelial morphotype, which do not sporulate and is unable to produce sclerotia. The second group includes one isolate, which sporulates profusely and does not produce sclerotia. All of them are unresponsive to light. Crosses between a repr…
