Aims: Alcohol dependence is a major public health issue with a need for new pharmacological treatments. The ALPADIR study assessed the efficacy and safety of baclofen at the target dose of 180 mg/day for the maintenance of abstinence and the reduction in alcohol consumption in alcohol-dependent patients. Methods: Three hundred and twenty adult patients (158 baclofen and 162 placebo) were randomized after alcohol detoxification. After a 7-week titration, the maintenance dose was provided for 17 weeks, then progressively decreased over 2 weeks before stopping...

A wide spectrum of pathological conditions may result from the interaction of Aspergillus fumigatus and the immune system of its human host. Allergic bronchopulmonary aspergillosis is one of the most severe Aspergillus fumigatus-related diseases due to possible evolution towards pleuropulmonary fibrosis and respiratory failure. Allergic bronchopulmonary aspergillosis occurs almost exclusively in cystic fibrosis or asthmatic patients. An estimated 8 to 10% of cystic fibrosis patients experience this condition...

New vaccine formulations are still highly anticipated in the near-future to face incoming health challenges, such as emergence or reemergence of severe infectious diseases, immunosenescence associated with elderly or the spread of pathogens resistant to antibiotics. In particular, new nanoparticle-based adjuvants are promising for sub-unit vaccines in order to elicit potent and long lasting immune responses with a better control on their safety. In this context, an innovative delivery system of protein antigens has been designed based on the chemical grafting of the antigen onto the shell of Nanostructured Lipid Carriers (NLC)...

Purpose: The impairment of visual functions is one of the most common complaints following mild traumatic brain injury (mTBI). Traumatic brain injury-associated visual deficits include blurred vision, reading problems, and eye strain. In addition, previous studies have found evidence that TBI can diminish early cortical visual processing, particularly for second-order stimuli. We investigated whether cortical processing of binocular disparity is also affected by mTBI. Methods: In order to investigate the influence of mTBI on global stereopsis, we measured the quick Disparity Sensitivity Function (qDSF) in 22 patients with mTBI...

Through the multicentric international GENHYPOPIT network, 10 transcription factor genes involved in pituitary development have been screened in more than 1200 patients with constitutional hypopituitarism over the past two decades. The present report summarizes the main lessons learned from this phenotype-based genetic screening: (1) genetically determined hypopituitarism does not necessarily present during childhood; (2) constitutional hypopituitarism may be characterized by a pure endocrine phenotype or by various combinations of endocrine deficits and visceral malformations; (3) syndromic hypopituitarism may also be observed in patients with POU1F1 or PROP1 mutations; (4) in cases of idiopathic hypopituitarism, extensive genetic screening identifies gene alterations in a minority of patients; (5) functional studies are imperfect in determining the involvement of an allelic variant in a specific pituitary phenotype...

Critical to determining vulnerability or resilience of reef corals to Ocean Acidification (OA) is a clearer understanding of the extent to which corals can control carbonate chemistry in their Extracellular Calcifying Medium (ECM) where the CaCO3 skeleton is produced. Here, we employ a mathematical framework to calculate ECM aragonite saturation state (Ωarag.(ECM)) and carbonate system ion concentration using measurements of calcification rate, seawater characteristics (temperature, salinity and pH) and ECM pH (pH(ECM))...

Controlling plasmonic systems with nanometer resolution in transparent films and their colors over large nonplanar areas is a key issue for spreading their use in various industrial fields. Using light to direct self-organization mechanisms provides high-speed and flexible processes to meet this challenge. Here, we describe a route for the laser-induced self-organization of metallic nanostructures in 3D. Going beyond the production of planar nanopatterns, we demonstrate that ultrafast laser-induced excitation combined with nonlinear feedback mechanisms in a nanocomposite thin film can lead to 3D self-organized nanostructured films...

Natural product chemistry began in Reims, France, in a pharmacognosy research laboratory whose main emphasis was the isolation and identification of bioactive molecules, following the guidelines of chemotaxonomy. The structure elucidation of new compounds of steadily increasing complexity favored the emergence of methodological work in nuclear magnetic resonance. As a result, our group was the first to report the use of proton-detected heteronuclear chemical shift correlation spectra for the computer-assisted structure elucidation of small organic molecules driven by atom proximity relationships and without relying on databases...

BACKGROUND: Growth monitoring of apparently healthy children aims at early detection of serious conditions through the use of both clinical expertise and algorithms that define abnormal growth. Optimization of growth monitoring requires standardization of the definition of abnormal growth, and the selection of the priority target conditions is a prerequisite of such standardization. OBJECTIVE: To obtain a consensus about the priority target conditions for algorithms monitoring children's growth...

A computer-aided, (13)C NMR-based dereplication method is presented for the chemical profiling of natural extracts without any fractionation. An algorithm was developed in order to compare the (13)C NMR chemical shifts obtained from a single routine spectrum with a set of predicted NMR data stored in a natural metabolite database. The algorithm evaluates the quality of the matching between experimental and predicted data by calculating a score function and returns the list of metabolites that are most likely to be present in the studied extract...

BACKGROUND: The capacity of Aedes mosquitoes to resist chemical insecticides threatens the control of major arbovirus diseases worldwide. Until alternative control tools are widely deployed, monitoring insecticide resistance levels and identifying resistance mechanisms in field mosquito populations is crucial for implementing appropriate management strategies. Metabolic resistance to pyrethroids is common in Aedes aegypti but the monitoring of the dynamics of resistant alleles is impeded by the lack of robust genomic markers...

Jiawei Zhou, Alexandre Reynaud, Robert F Hess
Several studies have shown that short-term monocular patching can induce ocular dominance plasticity in normal adults, in which the patched eye becomes stronger in binocular viewing. There is a recent study showing that exercise enhances this plasticity effect when assessed with binocular rivalry. We address one question, is this enhancement from exercise a general effect such that it is seen for measures of binocular processing other than that revealed using binocular rivalry? Using a binocular phase combination task in which we directly measure each eye's contribution to the binocularly fused percept, we show no additional effect of exercise after short-term monocular occlusion and argue that the enhancement of ocular dominance plasticity from exercise could not be demonstrated with our approach...

Membrane microdomains or "lipid rafts" have emerged as essential functional modules of the cell, critical for the regulation of growth factor receptor-mediated responses. Herein we describe the dichotomy between caveolin-1 and caveolin-2, structural and regulatory components of microdomains, in modulating proliferation and differentiation. Caveolin-2 potentiates while caveolin-1 inhibits nerve growth factor (NGF) signaling and subsequent cell differentiation. Caveolin-2 does not appear to impair NGF receptor trafficking but elicits prolonged and stronger activation of MAPK (mitogen-activated protein kinase), Rsk2 (ribosomal protein S6 kinase 2), and CREB (cAMP response element binding protein)...

Aims: Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome with various phenotypes and outcomes. The prognostic relevance of echocardiography and the E/e' ratio has previously been reported. We sought to study in addition, the value of estimated pulmonary pressure and left atrial size for diagnosing and determining a prognosis for HFpEF-patients in a prospective multi-centric cohort. Methods and results: Patients with an acute-HF event accompanied with NT-proBNP >300 pg/mL (BNP >100 pg/mL) and LVEF >45% were included (n = 237) and clinically reassessed using echo-Doppler after 4-8 weeks of HF treatment as part of the prospective KaRen HFpEF study...

Aims: Recent findings regarding hypertrophic cardiomyopathy (HCM) haemodynamics emphasized the relationship between symptoms, left ventricular outflow tract obstruction (LVOTO), and the preload condition as the venous return level. As various types of exercises have different effects on peripheral vascular beds, this study sought to compare upright treadmill exercise echocardiography (EE) to semi-supine bicycle EE in maximum provoked LVOTO in HCM patients. Methods and results: Semi-supine bicycle and upright treadmill EE were prospectively performed in HCM patients with New York Heart Association functional Class II...

An 80-membered library of gels composed of monofunctional 2-ethyl-2-oxazoline and 2-nonyl-2-oxazoline and one of four selected difunctional 2-oxazolines (containing either ether or ester bonds) were synthesized by microwave-assisted ring-opening polymerizations. The difunctional 2-oxazolines were prepared from the thiol-ene reaction of glycol dimercaptoacetate or 2,2'-(ethylenedioxy)diethanethiol and 2-but-3'-enyl-2-oxazoline or 2-dec-9'-enyl-2-oxazoline. 53 of the gels exhibited glass-transition temperatures, which ranged from -5...

In a series of previous publications we have proposed a framework for conceptualizing the optic nerve head (ONH) as a biomechanical structure. That framework proposes important roles for intraocular pressure (IOP), IOP-related stress and strain, cerebrospinal fluid pressure (CSFp), systemic and ocular determinants of blood flow, inflammation, auto-immunity, genetics, and other non-IOP related risk factors in the physiology of ONH aging and the pathophysiology of glaucomatous damage to the ONH. The present report summarizes 20 years of technique development and study results pertinent to the characterization of ONH connective tissue deformation and remodeling in the unilateral monkey experimental glaucoma (EG) model...

Our objectives were to describe, in Beagle dogs, the ontogenesis of beta (insulin-producing) and alpha (glucagon-producing) cells from fetal to early postnatal life and adulthood. In addition, to have some insight into interspecies comparison, Beagle dog pancreases were compared to pancreases from a Labrador and Chow Chow. At midgestation, the epithelium was dense, beta cells scarce, and alpha cells numerous and concentrated in the center of the pancreatic bud. From 36 to 45 days post conception (pc), beta cell numbers increased and the epithelium expanded and branched out...

During somatic hypermutation (SHM) of immunoglobulin genes, uracils introduced by activation-induced cytidine deaminase are processed by uracil-DNA glycosylase (UNG) and mismatch repair (MMR) pathways to generate mutations at G-C and A-T base pairs, respectively. Paradoxically, the MMR-nicking complex Pms2/Mlh1 is apparently dispensable for A-T mutagenesis. Thus, how detection of U:G mismatches is translated into the single-strand nick required for error-prone synthesis is an open question. One model proposed that UNG could cooperate with MMR by excising a second uracil in the vicinity of the U:G mismatch, but it failed to explain the low impact of UNG inactivation on A-T mutagenesis...
