Since the 1990s, the use of prescription opioids has largely spread, which has brought a real progress in the treatment of pain. The long-term use of prescription opioid is sometimes required, and may lead to pharmacological tolerance and withdrawal symptoms, i.e. pharmacological dependence on prescription opioids. Occasionally, this may also lead to misuse of prescription opioids (MPO). MPO preferentially occurs in vulnerable individuals, i.e., those with a young age, history of other addictive or psychiatric disorders, especially anxious and depressive disorders...

The concept of binge drinking (BD) refers to patterns of heavy episodic alcohol consumption, with BD primarily occurring among adolescents and young adults. Several official definitions of BD have been proposed, in particular by the World Health Organization, the National Institute on Alcoholism and Alcohol Abuse, and the Substance Abuse and Mental Health Services Administration. Nevertheless, none of these definitions address the psychosocial and medical consequences of the type of alcohol use seen in BD. In practice, BD can thus correspond to either hazardous or harmful use of alcohol (HUA), while the episodic nature of heavy drinking in BD means that it does not meet the criteria for 'alcohol dependence'...

Genetic (Pinb-D1 alleles) and environment (through vitreousness) have important effects on bread wheat milling behavior. SKCS optimal values corresponding to soft vitreous or hard mealy grains were defined to obtain the highest total flour yield. Near-isogenic lines of bread wheat that differ in hardness, due to distinct puroindoline-b alleles (the wild type, Pinb-D1a, or the mutated forms, Pinb-D1b or Pinb-D1d), were grown in different environments and under two nitrogen fertilization levels, to study genetic and environmental effects on milling behavior...

When patients are incapacitated and face serious illness, family members must make medical decisions for the patient. Medical decision sciences give only modest attention to the relationships among patients and their family members, including impact that these relationships have on the decision-making process. A review of the literature reveals little effort to systematically apply a theoretical framework to the role of family interactions in proxy decision making. A family systems perspective can provide a useful lens through which to understand the dynamics of proxy decision making...

Neurachne is the only known grass lineage containing closely related C3, C3-C4 intermediate and C4 species, making it an ideal taxon with which to study the evolution of C4 photosynthesis in the grasses. To begin dissecting the molecular changes that led to the evolution of C4 photosynthesis in this group, the cDNAs encoding four distinct β-carbonic anhydrase (CA) isoforms were characterized from leaf tissue of Neurachne munroi (C4), N. minor (C3-C4), and N. alopecuroidea (C3). Two genes (CA1 and CA2) each encode two different isoforms: CA1a, CA1b, CA2a and CA2b...

Valvular heart disease remains a large public health problem for all societies; it attracts the attention of public health organizations, researchers and governments. Valve substitution is an integral part of the treatment for this condition. At present, the choice of valve prosthesis is either tissue or mechanical. Tissue valves have become increasingly popular in spite of unresolved problems with durability, hemodynamics, cost and need for anticoagulation therapy. As a consequence, mechanical valve innovation has virtually ceased; the last successful mechanical design is 25 years old...

Institutionalization is generally a consequence of functional decline driven by physical limitations, cognitive impairments, and/or loss of social supports. At this stage, intervention to reverse functional losses is often too late. To be more effective, geriatric medicine must evolve to intervene at an earlier stage of the disability process. Could nursing homes (NHs) transform from settings in which many residents dwell to settings in which the NH residents and those living in neighboring communities benefit from staff expertise to enhance quality of life and maintain or slow functional decline? A task force of clinical researchers met in Toulouse on December 2, 2015, to address some of these challenges: how to prevent or slow functional decline and disabilities for NH residents and how NHs may promote the prevention of functional decline in community-dwelling frail elderly...

PURPOSE: Few in vivo studies have been reported describing efficacy and duration of antibiotic lock therapy (ALT) with daptomycin (DPT) for long-term catheter-related bloodstream infections (CRBSI) due to coagulase-negative staphylococci (CoNS). We retrospectively analysed the efficacy of short-course ALT with DPT in combination with systemic treatment (ST) for CoNS-associated CRBSI in our hospital. METHODS: Patients admitted for CoNS-associated CRBSI and treated with DPT as ALT and ST were retrospectively analysed...

Adeno-associated viruses (AAVs) have become powerful tools in neuroscience for both basic research and potential therapeutic use. They have become especially important tools for optogenetic experiments based on their ability to achieve transgene expression in postmitotic neurons with regional selectivity. With the use of appropriate promoter elements they can achieve cellular specificity as well. One population of neurons that plays a central role in human neurodegenerative and psychiatric diseases are the dopamine neurons of the midbrain...

OBJECTIVES: Proteases are key mediators of pain and altered enteric neuronal signalling, although the types and sources of these important intestinal mediators are unknown. We hypothesised that intestinal epithelium is a major source of trypsin-like activity in patients with IBS and this activity signals to primary afferent and enteric nerves and induces visceral hypersensitivity. DESIGN: Trypsin-like activity was determined in tissues from patients with IBS and in supernatants of Caco-2 cells stimulated or not...

BACKGROUND: Reduced exercise capacity severely impacts quality of life in pulmonary Langerhans cell histiocytosis. Ascertaining mechanisms that impair exercise capacity is necessary to identify targets for symptomatic treatments. METHODS: Dyspnea, pulmonary function tests and cardiopulmonary exercise test were analysed in 62 study participants. Data were compared between subjects with impaired and normal aerobic capacity (V'O2 peak less than 84% versus 84% predicted or more)...

BACKGROUND: While mitochondrial DNA (mtDNA) copy number is strictly regulated during differentiation and according to cell type, very little is known regarding the mechanism which accurately controls mtDNA copy number in human. Exon 2 of the human POLG gene, encoding the catalytic subunit of the mitochondrial-specific DNA polymerase gamma, contains a CpG island, highly conserved in mice and human. Changes of DNA methylation at the POLG locus have been shown to modulate mtDNA copy number during cell differentiation in both mouse and human...

Progressive weakness is a typical feature of Duchenne muscular dystrophy (DMD) patients and is exacerbated in the benign mdx mouse model by in vivo treadmill exercise. We hypothesized a different threshold for functional adaptation of mdx muscles in response to the duration of the exercise protocol. In vivo weakness was confirmed by grip strength after 4, 8 and 12 weeks of exercise in mdx mice. Torque measurements revealed that exercise-related weakness in mdx mice correlated with the duration of the protocol, while wild-type (wt) mice were stronger...

Fingolimod, a sphingosine-1-phosphate receptor (S1PR) agonist, is clinically available to treat multiple sclerosis and is showing promise in treating stroke. We investigated if fingolimod provides long-term protection from experimental neonatal germinal matrix hemorrhage (GMH), aiming to support a potential mechanism of acute fingolimod-induced protection. GMH was induced in P7 rats by infusion of collagenase (0.3 U) into the right ganglionic eminence. Animals killed at 4 weeks post-GMH received low- or high-dose fingolimod (0...

BACKGROUND: The role of migration as a risk factor remains unknown for mood disorders because of poor data. We sought to examine the prevalence and severity of mood disorders (bipolar disorder (BD), unipolar depressive disorder (UDD) and dysthymia) in first, second, and third generation migrants in France. METHODS: The Mental Health in the General Population survey interviewed 38,694 individuals. The prevalence of lifetime mood disorders, comorbidities, and clinical features was compared between migrants and non-migrants and by generation...

The first two reactions of C4 photosynthesis are catalysed by carbonic anhydrase (CA) and phosphoenolpyruvate carboxylase (PEPC) in the leaf mesophyll (M) cell cytosol. Translatome experiments using a tagged ribosomal protein expressed under the control of M and bundle-sheath (BS) cell-specific promoters showed transcripts encoding CA3 from the C4 species Flaveria bidentis were highly enriched in polysomes from M cells relative to those of the BS. Localisation experiments employing a CA3-green fluorescent protein fusion protein showed F...

Broomrapes are holoparasitic plants spreading through seeds. Each plant produces hundreds of thousands of seeds which remain viable in the soils for decades. To limit their spread, drastic measures are being taken and the contamination of a commercial seed lot by a single broomrape seed can lead to its rejection. Considering that broomrapes species identification from a single seed is extremely difficult even for trained botanists and that among all the described species, only a few are really noxious for the crops, numerous seed lots are rejected because of the contamination by seeds of non-noxious broomrape species...
