Phototherapy is a cost-effective treatment with a safe side-effect profile for the management of a wide range of dermatoses. Although one of the most common indications for phototherapy is psoriasis, the use of phototherapy for psoriasis has seen a decline in the U.S.A. Data from the National Ambulatory Medical Care Survey indicate a 94% decrease of physician visits for phototherapy between 1994 and 1998. This article is protected by copyright. All rights reserved.

We demonstrate, based on experimental and theoretical evidences, that the isolated [2(CH3CN)2]2+ complex prepared in CH3CN and containing a mixed-valent {Cu2II,IS} core evolves towards a new [2(CH3CN)3]2+ species upon solvation in CH3CN. Unlike its type III structural analog [2(H2O)(OTf)]+ active toward N2O reduction, this new type I compound is inactive. This outcome opens new perspectives for a rational for N2O activation using bio-inspired Cu/S complexes, especially on the role of the valence localization/delocalization and the Cu-Cu bond on the reactivity...

Designing systems that merge the advantages of heterogeneous catalysis, enzymology and molecular catalysis represents the next major goal for sustainable chemistry. Cross-linked enzyme crystals display most of these essential assets (well-designed mesoporous support, protein selectivity, molecular recognition of substrates). Nevertheless, a lack of reaction diversity, particularly in the field of oxidation, remains a constraint for their increased use in the field. Here, thanks to the design of cross-linked artificial non-heme iron oxygenase crystals, we filled this gap by developing bio-based heterogeneous catalysts capable of oxidizing carbon-carbon double bonds...

The sandarac resin (Tetraclinis articulata) has been long used for its properties, mostly as a varnish component. Called juniper resin until the nineteenth century, the real botanical origin of sandarac is still unclear. The first approach to this issue is the review of the evolution of the etymology, terminology, and botanical description of sandarac through time. It seems that sandarac was mainly coming from T. articulata but the use of some juniper resins before the twentieth century is not to be excluded...

INTRODUCTION: Tau hyperphosphorylation and neurofibrillary tangles are histopathologic hallmarks of tauopathies. Histamine H3-receptor antagonists have been proposed to reduce tau hyperphosphorylation in preclinical models. METHODS: We evaluated the ability of SAR110894, a selective histamine H3-receptor antagonist, to inhibit tau pathology and prevent cognitive deficits in a tau transgenic mouse model (THY-Tau22). RESULTS: SAR110894 treatment for 6 months (but not 2 weeks) in THY-Tau22 mice decreased both tau hyperphosphorylation at pSer396-pSer404 (AD2 signal) in the hippocampus and the number of AT8 (pSer199/202-Thr205) positive cells in the cortex and decreased the formation of neurofibrillary tangles in the cortex, hippocampus, and amygdala...

Overhydration is a frequent complication in dialysis patients. It has been linked with hypertension, left ventricular hypertrophy, arterial stiffness, atherosclerosis uremic cardiomyopathy, and all-cause mortality or cardiovascular morbidity. In addition, predialysis underhydration is also associated with increased risk of death in ESRD patients. In this context, the optimal evaluation of hydration status is a must. However, this mission is not easy or accurate. In the last 10 years, several new methods have been tested in dialysis patients, particularly bioimpedance and lung ultrasonography...

OBJECTIVE: The circadian clock regulates glucose metabolism by mediating the activity of metabolic enzymes, hormones, and transport systems. Breakfast skipping and night eating have been associated with high HbA1c and postprandial hyperglycemia after lunch and dinner. Our aim was to explore the acute effect of breakfast consumption or omission on glucose homeostasis and clock gene expression in healthy individuals and individuals with type 2 diabetes. RESEARCH DESIGN AND METHODS: In a crossover design, 18 healthy volunteers and 18 volunteers with 14...

This study examined the difficulties couples face in relation to anorexia nervosa. Using interpretative phenomenological analysis, five couples in which one of the partners lives with anorexia nervosa were interviewed separately. The findings are conceptualized into three areas: first, the encounter 'at the crossroads between remission and relapse'; second, the way that 'anorexia reveals itself'; and finally, the way the 'ménage à trois' works, including the illness fully as part of the couple. Psychotherapists should take into account the context of the couple and the complex interaction between the couple and the illness to support both partners' development of appropriate responses...

In 1999, French legislators asked health insurance funds to develop a système national d'information interrégimes de l'Assurance Maladie (SNIIRAM) [national health insurance information system] in order to more precisely determine and evaluate health care utilization and health care expenditure of beneficiaries. These data, based on almost 66 million inhabitants in 2015, have already been the subject of numerous international publications on various topics: prevalence and incidence of diseases, patient care pathways, health status and health care utilization of specific populations, real-life use of drugs, assessment of adverse effects of drugs or other health care procedures, monitoring of national health insurance expenditure, etc...

Reflectance spectroscopy, ultraviolet (UV)-fluorescence spectroscopy, and multispectral imaging have been widely employed for pigment identification on paintings. From ancient times to the present, lead white, zinc white, and titanium white have been the most important white pigments used for paintings and they are used as pigment markers for dating a work of art. The spectral behavior of these pigments is reported in several scientific papers and websites, but those of their mixtures are quite unknown. We present a combined nondestructive approach for identifying mixtures of lead white, zinc white, and titanium white as powder and dispersed in two different binder media (egg yolk and linseed oil) by using reflectance spectroscopy, spectrofluorimetry, multispectral reflectance and UV-fluorescence imaging...

Hybrid nanogels, composed of thermoresponsive polymers and superparamagnetic nanoparticles, are attractive nanocarriers for biomedical applications, being able-as a polymer matrix-to uptake and release high quantities of chemotherapeutic agents and-as magnetic nanoparticles-to be heated when exposed to an alternative magnetic field (AMF), better known as magnetic hyperthermia. Herein, biocompatible, pH-responsive, magnetoresponsive, and thermoresponsive nanogels, based on oligo(ethylene glycol) methyl ether methacrylate monomers and a methacrylic acid comonomer were prepared by conventional precipitation radical copolymerization in water, post-assembled by complexation with iron oxide magnetic nanoparticles (MNPs) of maghemite (γ-Fe2O3), and loaded with an anticancer drug (doxorubicin, DOX), for remotely controlled drug release by a "hot spot", as an athermal magnetic hyperthermia strategy against cancer...

OBJECTIVE: Osteoprotegerin (OPG) is closely related to insulin resistance and bone remodeling. However, no studies have examined the role of OPG in postmenopausal women with coexistent impaired glucose and bone regulation. The present study investigated the relationship of OPG to glucose homeostasis and insulin resistance in postmenopausal osteoporotic women with different types of glucose tolerance. METHODS: In all, 114 postmenopausal osteoporotic women were divided into three groups according to glucose tolerance status: 51 with normal glucose tolerance (NGT, group 1), 31 with impaired glucose tolerance (IGT, group 2), and 32 with type 2 diabetes mellitus (DM, group 3)...

Although end-of-life medical spending is often viewed as a major component of aggregate medical expenditure, accurate measures of this type of medical spending are scarce. We used detailed health care data for the period 2009-11 from Denmark, England, France, Germany, Japan, the Netherlands, Taiwan, the United States, and the Canadian province of Quebec to measure the composition and magnitude of medical spending in the three years before death. In all nine countries, medical spending at the end of life was high relative to spending at other ages...

Dendritic cells (DCs) have essential roles in early detection of pathogens and activation of both innate and adaptive immune responses. Whereas human DCs are resistant to productive HIV-1 replication, they have a unique ability to take up virus and transmit it efficiently to T lymphocytes. By doing that, HIV-1 may evade, at least in part, the first line of defense of the immune system, exploiting DCs instead to facilitate rapid infection of a large pool of immune cells. While performing an shRNA screen in human primary monocyte-derived DCs, to gain insights into this cell biological process, we discovered the role played by tetraspanin-7 (TSPAN7)...

The crystallizable fragment (Fc) of the immunoglobulin class G (IgG) is an attractive scaffold for the design of novel therapeutics. Upon engineering the C-terminal loops in the CH3 domains, Fcabs (Fc domain with antigen-binding sites) can be designed. We present the first crystal structures of Fcabs, i.e., of the HER2-binding clone H10-03-6 having the AB and EF loop engineered and the stabilized version STAB19 derived by directed evolution. Comparison with the crystal structure of the Fc wild-type protein reveals conservation of the overall domain structures but significant differences in EF-loop conformations...

The aim of this protocol is to describe how to measure and quantify the amount of HIV-1 particles and dextran molecules internalized in human monocyte derived dendritic cells (MDDCs), using three different techniques: flow cytometry, quantitative PCR and confocal microscopy. BACKGROUND: This protocol was developed in order to assess the changes of HIV-1 internalization upon disruption of actin nucleation in human monocyte derived dendritic cells. Following a shRNA screen to identify genes important for HIV-1 transfer from dendritic cells to T cells, we observed that a disruption of actin nucleation leads to a switch from actin rich dendrites to blebs, due to an excess of actomyosin contraction...

Human cosavirus and saffold virus are both newly discovered members of the Picornaviridae family. It has been suggested that these viruses may be the causative agents of acute gastroenteritis. In this study, 1093 stool samples collected from patients with acute gastroenteritis between January 2014 and December 2016, were screened for cosavirus and saffold virus using reverse transcription-polymerase chain reaction. The viral genotypes were then established via nucleotide sequencing. Here, cosavirus was detected in 16 of 1093 stool samples (1...
