OBJECTIVE: Outcomes of systemic lupus erythematosus (SLE) and lupus nephritis (LN) are highly heterogeneous among some populations because of interactions between genetic, epigenetic, environmental, and socioeconomic factors. A better characterization of social and ethnic disparities in mixed populations may thus help to develop individualized treatment regimens. MATERIALS AND METHODS: Retrospective observational study including all patients with LN diagnosed between January 1993 and January 2014 in the only Nephrology Department of French Polynesia...

Hybrid organic-inorganic halide perovskites are low-cost solution-processable solar cell materials with photovoltaic properties that rival those of crystalline silicon. The perovskite films are typically sandwiched between thin layers of hole and electron transport materials, which efficiently extract photogenerated charges. This affords high-energy conversion efficiencies but results in significant performance and fabrication challenges. Herein we present a simple charge transport layer-free perovskite solar cell, comprising only a perovskite layer with two interdigitated gold back-contacts...

BACKGROUND: We proposed to determine the complication and hospital admission rates for patients with total hip arthroplasty (THA) done by a single surgeon in a stand-alone ambulatory surgical center with same-day discharge. Given the recent emphasis on bundled payments for a 90-day episode of care, this same time frame after surgery was chosen to determine patient outcomes. METHODS: The records of patients with THAs done through a direct anterior approach by a single surgeon at 2 separate ambulatory surgery centers were reviewed...

xCT is the specific chain of the cystine/glutamate antiporter, which is widely reported to support anti-oxidant defenses in vivo. xCT is therefore at the crossroads between two processes that are involved in schizophrenia: oxidative stress and glutamatergic neurotransmission. But data from human studies implicating xCT in the illness and clarifying the upstream mechanisms of xCT imbalance are still scarce. Low glutathione (GSH) levels and genetic risk in GCLC (Glutamate-Cysteine Ligase Catalytic subunit), the gene of limiting synthesizing enzyme for GSH, are both associated with schizophrenia...

14-3-3sare a family of ubiquitously expressed adaptor proteins that regulate hundreds of functionally diverse 'client proteins.' In humans, there are seven isoforms with conserved structure and function. 14-3-3s typically bind to client proteins at phosphorylated serine/threonine motifs via a linear binding groove. Binding can have a variety of effects on the stability, activity and/or localization of the client protein. 14-3-3s are generating significant interest as potential drug targets for their involvement in cellular homeostasis and disease...

REVIEW
Téo Fournier, Joseph Schacherer
Dissecting the genetic basis of natural phenotypic variation is a major goal in biology. We know that most traits are strongly heritable. However, their genetic architecture is a long-standing question, which is unfortunately confounded by the lack of complete knowledge of the genetic components as well as their phenotypic effect in a specific genetic background. Many genetic variants are known to affect phenotypes but the same functional variant can have a different effect on the phenotype in different individuals of the same species...

We report the results of an experimental study related to the relaxation of the nuclear spin isomers of the water molecule in a supersonic expansion. Rovibrational lines of both ortho- and para- spin isomers were recorded in the spectral range of H2O stretching vibrations around 3700 cm(-1) using FTIR direct absorption. Water vapor seeded either in argon, helium, oxygen or in a mixture of oxygen and argon was expanded into vacuum through a slit nozzle. Partial water vapor pressure in the mixture varied in a wide range from 1...

An asymmetric total synthesis of (+)-6-hydroxythiobinupharidine (1b) and (-)-6-Hydroxythionuphlutine (2b), a set of hemi-aminal containing dimeric sesquiterpenes isolated from yellow water lilies of the Nuphar genus, is described. The central bis-spirocyclic thiolane was forged through the Stevens rearrangement of a sulfonium ylide, generated in-situ from the coupling of a copper carbenoid with a spirocyclic thietane. This strategy diverges both from the proposed biosynthesis1 and previous syntheses of this family of alkaloids,2,3 all of which employ dimerization of symmetric monomers to form the aforementioned central thiolane...

Interpretation of variants of unknown significance (VUS) is a major challenge for laboratories performing molecular diagnosis of hereditary breast and ovarian cancer (HBOC), especially considering that many genes are now known to be involved in this syndrome. One important way these VUS can have a functional impact is through their effects on RNA splicing. Here we present a custom RNA-Seq assay plus bioinformatics and biostatistics pipeline to analyse specifically alternative and abnormal splicing junctions in 11 targeted HBOC genes...

Insecticide resistance is an economically important example of evolution in response to intense selection pressure. Here, the genetics of resistance to the neonicotinoid insecticide imidacloprid is explored using the Drosophila Genetic Reference Panel, a collection of inbred Drosophila melanogaster genotypes derived from a single population in North Carolina. Imidacloprid resistance varied substantially among genotypes, and more resistant genotypes tended to show increased capacity to metabolize and excrete imidacloprid...

OBJECTIVES: To report the long-term survival of transplanted kidneys in patients with a continent urinary diversion. METHODS: Between January 1987 and July 2015, 16 patients with a median age of 37 years (range 21-63 years) underwent kidney transplantation on a continent urinary diversion. A total of 14 patients presented irreversible dysfunction of the lower urinary tract, and two patients had required radical cystectomy because of bladder cancer. All continent urinary diversions were carried out before the transplantation...

Objective: The outcome of Fournier's gangrene (FG) may be affected by comorbidities, demographics, and choice of treatment modality. We sought to evaluate our institution's management protocol of FG measured by mortality rate (MR) and length of hospital stay (LHS) in a retrospective cohort study. Approach: A database of 20 FG cases at our institution throughout the 2009-2016 study period was assembled by a retrospective review of medical records. A Fournier's Gangrene Severity Index Score (FGSIS) was calculated for each case...

During development, tightly regulated gene expression programs control cell fate and patterning. A key regulatory step in eukaryotic transcription is the assembly of the pre-initiation complex (PIC) at promoters. The PIC assembly has mainly been studied in vitro, and little is known about its composition during development. In vitro data suggests that TFIID is the general transcription factor that nucleates PIC formation at promoters. Here we show that TAF10, a subunit of TFIID and of the transcriptional co-activator SAGA, is required for the assembly of these complexes in the mouse embryo...

Cerebrospinal fluid (CSF) biomarkers might be useful in predicting outcome after aneurysmal subarachnoid hemorrhage (aSAH). It was the aim to determine whether tau and amyloid beta CSF concentrations predict functional, health-related quality of life (hrQoL), and neuropsychological outcomes after aSAH. Ventricular CSF was obtained from n = 24 aSAH patients at admission (D0), day 2 (D2), and day 6 (D6). CSF total (t)Tau, phosphorylated (p)Tau(181P), and amyloid beta(1-40 and 1-42) (Aβ40/Aβ42) levels were compared between patients with favorable and unfavorable functional (modified Rankin Scale (mRS)), hrQoL (Euro-Qol (EQ-5D)), and neuropsychological outcomes at 3 (3 m) and 12 months (12 m)...

INTRODUCTION: Previous investigations of test-retest reliability of cerebral blood flow (CBF) at rest measured with pseudo-continuous Arterial Spin Labeling (pCASL) demonstrated good reliability, but are limited by the use of similar scanner platforms. In the present study we examined test-retest reliability of CBF in regions implicated in emotion and the default mode network. MATERIAL AND METHODS: We measured absolute and relative CBF at rest in thirty-one healthy subjects in two scan sessions, one week apart, at four different sites and three different scan platforms...

Psychological comorbidity is highly present in irritable bowel syndrome (IBS). Recent research points to a role of intestinal microbiota in visceral hypersensitivity, anxiety, and depression. Increased disease reactivity to psychological stress has been described too. A few clinical studies have attempted to identify features of dysbiosis in IBS. While animal studies revealed strong associations between stress and gut microbiota, studies in humans are rare. This review covers the most important studies on intestinal microbial correlates of psychological and clinical features in IBS, including stress, anxiety, and depression...
