Objectives: HCQ has been described as having a beneficial effect in patients with APS but its mechanism of action is unclear. We hypothesized that HCQ may have effects on subnormal angiogenesis, inflammation and haemostatic biomarkers seen in APS. The aim of our study was to assess laboratory markers [annexin A5 (AnxA5) anticoagulant activity, tissue factor (TF) levels, thromboelastography (TEG), CRP, Bb, C3a and VEGF] in HCQ-naïve patients with aPL at baseline and after commencing HCQ...

: The duration of dual antiplatelet therapy (DAPT) after coronary stenting has been evaluated in randomized studies with apparently conflicting results. Prolonged DAPT reduces late stent thrombosis and myocardial infarction, but at the expenses of more hemorrhages. On the contrary, bleedings are associated with higher morbidity and mortality. Thus, in patients at high risk of bleeding, the less effective bare-metal stents could be preferred to drug-eluting stents (DES) due to the shortened DAPT needed. However, new DES technology carries a lower risk of stent thrombosis and casts doubts on the recommended prolonged DAPT regimen after DES...

In this paper, we propose a performance monitoring and failure prediction method in optical networks based on machine learning. The primary algorithms of this method are the support vector machine (SVM) and double exponential smoothing (DES). With a focus on risk-aware models in optical networks, the proposed protection plan primarily investigates how to predict the risk of an equipment failure. To the best of our knowledge, this important problem has not yet been fully considered. Experimental results showed that the average prediction accuracy of our method was 95% when predicting the optical equipment failure state...

In this research work, two consecutive dispersive solid/liquid phase microextractions based on efficient extraction media were developed for the influential and clean pre-concentration of clonazepam and lorazepam from complicated bio-samples. The magnetism nature of the proposed nanoadsorbent proceeded the clean-up step conveniently and swiftly (∼5min), pursued by a further enrichment via a highly effective and rapid emulsification microextraction process (∼4min) based on a deep eutectic solvent (DES). Finally, the instrumental analysis step was practicable via high performance liquid chromatography-ultraviolet detection...

As one of the most oestrogenic synthetic compounds in water environment, diethylstilbestrol (DES) has been studied for decades. Some studies showed that DES can be removed by ultraviolet (UV) irradiation. However, no one has paid attention to the formation of oestrogenic disinfection by-products (DBPs) and the persistence of DES in surface water remains a mystery. In this study, UV was found to be very effective in removing oestrogenic activity regardless of water quality. Three oestrogenic DBPs were specifically isolated by oestrogen receptor-based affinity chromatography and identified as 9,10-diethylphenanthrene-3,6-diol, cis-DES and Z,Z-dienestrol...

INTRODUCTION: Numerous studies reported dentin bridge formation after pulp capping with tricalcium silicates. By contrast, pulp capping with resins leads to pulp toxicity and inflammation. Hybrid materials made up of tricalcium silicates and resins have also been developed to be used in direct pulp capping. This work was designed to study the consequences of adding resins to tricalcium silicates by investigating TheraCal (BISCO, Lançon De Provence, France) and Biodentine (Septodont, Saint Maur des Fosses, France) interactions with the dental pulp...

BACKGROUND: The cyclin-dependent kinase inhibitor, p21, is well known for its role in cell cycle arrest. Novel anti-cancer agents that deplete iron pools demonstrate marked anti-tumor activity and are also active in regulating p21 expression. These agents induce p21 mRNA levels independently of the tumor suppressor, p53, and differentially regulate p21 protein expression depending on the cell-type. Several chelators, including an analogue of the potent anti-tumor agent, di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT), have entered clinical trials, and thus, their molecular mechanism of action is crucial to assess...

PURPOSE: To use network meta-analysis (NMA) to determine the optimal endovascular strategy for management of femoropopliteal peripheral artery disease (PAD) given the lack of multiple prospective randomized trials to guide treatment decisions. MATERIALS AND METHODS: NMA is a new meta-analytic method that permits comparisons among any 2 therapies by combining results of a collection of clinical trials conducted in the same or similar patient population. NMA was used to analyze data from 15 randomized controlled trials (RCTs) and 10 prospective, multicenter, single-arm trials (combined evidence [CE] NMA) that evaluated target lesion revascularization (TLR) for 5 endovascular strategies: bare metal stent (BMS), polymer-covered metal stent (CMS), drug-eluting stent (DES), drug-coated balloon (DCB) and percutaneous transluminal angioplasty (PTA)...

Maisons des adolescents (Adolescent Centres) have a key role to play in the prevention of radicalisation. The Strasbourg centre uses a secondary prevention approach with an assessment of the potential danger of the adolescent's situation, orientation towards relevant professionals where necessary, and support which is both symptomatic and which targets the vulnerabilities of the individual and the family. Faced with this new adolescent symptom, the support, designed over the long term and ideally in partnership, must be able to adapt...

Bluetongue virus (BTV) is the type species of genus Orbivirus within family Reoviridae. Bluetongue virus is transmitted between its ruminant hosts by the bite of Culicoides spp. midges. Severe BT cases are characterized by symptoms including hemorrhagic fever, particularly in sheep, loss of productivity, and death. To date, 27 BTV serotypes have been documented. These include novel isolates of atypical BTV, which have been almost fully characterized using deep sequencing technologies and do not rely on Culicoides vectors for their transmission among hosts...
