We report the synthesis and remarkable properties of phosphine P(NIiPr)3 (NIiPr = 1,3-diisopropyl-4,5-dimethylimidazolin-2-ylidenamino), a crystalline solid accessible through a short and scalable route. Evaluation of the electron donor properties reveals a TEP value of 2029.7 cm-1 for the new phosphine that is significantly lower than those of all known phosphines or even N-heterocyclic carbenes. Moreover, P(NIiPr)3 is more basic [pKBH+(MeCN) = 38.8] than Verkade's proazaphosphatranes, thus being the strongest reported nonionic phosphorus(III) superbase...

BACKGROUND AND OBJECTIVES: Inguinal hernia repair is among the most common procedures performed worldwide and the laparoscopic totally extraperitoneal (TEP) approach is a recognized and effective surgical technique. Although technically advantageous because of the option of no mesh fixation and no need for creation of a peritoneal flap resulting, in less postoperative pain and faster recovery, TEP has not achieved the popularity it deserves, mainly because of its complexity and steep learning curve...

Concurrent recording of electroencephalography (EEG) during transcranial magnetic stimulation (TMS) is an emerging and powerful tool for studying brain health and function. Despite a growing interest in adaptation of TMS-EEG across neuroscience disciplines, its widespread utility is limited by signal processing challenges. These challenges arise due to the nature of TMS and the sensitivity of EEG to artifacts that often mask TMS-evoked potentials (TEP)s. With an increase in the complexity of data processing methods and a growing interest in multi-site data integration, analysis of TMS-EEG data requires the development of a standardized method to recover TEPs from various sources of artifacts...

Despite important progress in identifying the molecules that participate in the immune response of Drosophila melanogaster to microbial infections, the involvement of thioester-containing proteins (TEPs) in the antibacterial immunity of the fly is not fully clarified. Previous studies mostly focused on identifying the function of TEP2, TEP3 and TEP6 molecules in the D. melanogaster immune system. Here, we investigated the role of TEP4 in the regulation and function of D. melanogaster host defense against 2 virulent pathogens from the genus Photorhabdus, i...

There are several techniques for repair of symptomatic inguinal and femoral hernias. There is an increased acceptance and tendency favoring minimally invasive procedures, such as plug or transinguinal preperitoneal mesh prosthesis (TIPP) and endoscopic procedures, such as totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) repair. In the present review the classical techniques of Irving L. Lichtenstein (1986) and Jean Rives (1965), two indispensable procedures, are presented and the results from the literature are discussed...

BACKGROUND: Schizophrenia is a severe mental disorder that affects 1 % of the world's population, including 600,000 people in France. Persons with schizophrenia (PWS) have excess mortality (their life expectancy is reduced by 20 %) and excess morbidity. In addition, such persons may have a large number of missing or decayed teeth. Dental caries and periodontal measurement indexes are often twice as high as the level found in the general population. Poor oral health can also affect quality of life and oral health is inseparable from general health...

An investigation of a sea water reverse osmosis desalination facility located in western Saudi Arabia has shown that aquifer treatment of the raw sea water provides a high degree of removal of natural organic matter (NOM) that causes membrane biofouling. The aquifer is a carbonate system that has a good hydraulic connection to the sea and 14 wells are used to induce sea water movement 400 to 450 m from the sea to the wells. During aquifer transport virtually all of the algae, over 90% of the bacteria, over 90% of the biopolymer fraction of NOM, and high percentages of the humic substance, building blocks, and some of the low molecular weight fractions of NOM are removed...

"Liquid biopsies" are blood based assays used to detect and analyze circulating tumor products, including circulating tumor cells (CTCs), circulating tumor DNA (ctDNA), circulating messenger RNA (mRNA), circulating microRNA (miRNA), circulating exosomes, and tumor educated platelets (TEP). For patients with gastrointestinal (GI) malignancies, blood based biopsies may offer several advantages. First, tumor tissue samples are often challenging to procure, and when obtainable, are often insufficient for genomic profiling...

Several studies have explored the relationship between C-reactive protein (CRP), serum lipid levels, risk of suicide and alexithymia or impulsivity in mood or anxiety disorders. However, to date, no study has evaluated the effects of anhedonia on these parameters. The aim of the study was to evaluate the relationship between anhedonia, alexithymia, impulsivity, suicidal ideation, recent suicide attempt, C-reactive protein (CRP) and lipid levels in patients with mood or anxiety disorders. One hundred and twenty-two inpatients with mood or anxiety disorders were recruited...

BACKGROUND: data: Laparoscopic adult hernia repair has the clinical advantage of allowing the surgeon to explore asymptomatic contralateral inguinal hernia. We conduct a retrospective study to compare the occurrence of contralateral metachronous inguinal hernia (CMIH) after laparoscopic total extraperitoneal (TEP) repair with or without contralateral exploration. METHODS: One hundred and fifty-one consecutive patients undergoing unilateral laparoscopic TEP repair during November 2007 to November 2012 were enrolled into groups with contralateral or no contralateral exploration...

INTRODUCTION: Spigelian hernia (SH) is a rare ventral hernia occurring near the lateral border of the rectus muscle. The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature. Here, we report a case of totally extra-peritoneal (TEP) repair for bilateral SHs. PRESENTATION OF CASE: A 74-year-old Japanese man presented with asymptomatic bulges in the right lower abdominal quadrant...

Membrane bioreactor (MBR) technology is becoming increasingly popular as wastewater treatment due to the unique advantages it offers. However, membrane fouling is being given a great deal of attention so as to improve the performance of this type of technology. Recent studies have proven that the application of electrochemical processes to MBR represents a promising technological approach for membrane fouling control. In this work, two intermittent voltage gradients of 1 and 3 V/cm were applied between two cylindrical perforated electrodes, immersed around a membrane module, at laboratory scale with the aim of investigating the treatment performance and membrane fouling formation...

Exopolymer particles are found throughout the ocean and play a significant biogeochemical role in carbon cycling. Transparent exopolymer particles (TEP) are composed of acid polysaccharides and Coomassie staining particles (CSP) are proteins. TEP have been extensively studied in the ocean, while CSP have been largely overlooked. The objective of this research was to determine the role of stress and cell permeability in the formation of TEP and CSP. The diatom Thalassiosira weissflogii and cyanobacterium Synechococcus elongatus were grown in batch cultures and exposed to hydrogen peroxide (0, 10, and 100 μM) as an environmental stressor...

Importance: Voice prosthesis (VP) device life is a limiting factor of tracheoesophageal (TE) voice restoration that drives patient satisfaction, health care costs, and overall burden. Historic data suggest that TE VPs have an average device life of generally 3 to 6 months, but these data are typically derived from small samples using only 1 or 2 devices. Objective: To reexamine current device life in a large, contemporary cancer hospital in the United States that uses a wide assortment of VPs...

Pseudoarhtrosis is a relatively frequent complication of fractures, in which the lack of mechanical stability and biological stimuli results in the failure of bone union, most frequently in humerus and tibia. Treatment of recalcitrant pseudoarthrosis relies on the achievement of satisfactory mechanical stability combined with adequate local biology. Herein we present two cases of atrophic pseudoarthrosis that received a Tissue Engineering Product (TEP) composed of autologous Bone Marrow-derived Mesenchymal Stromal Cells (BM-MSC) combined with deantigenised trabecular bone particles from tissue bank...

Non-protein coding RNAs in different flavors (miRNAs, piRNAs, snoRNAs, lncRNAs, SHOT-RNAs), exosomes, large oncosomes, exoDNA and now tumor-educated platelets (TEPs) have emerged as crucial signal transmitting, transporting and regulating devices of cells in the last two decades. They are also establishing themselves increasingly in the realm of tumor research. We are currently witnessing a mushrooming of candidate entities for diagnostic and prognostic cancer detection and characterization tests that could have a major impact on how this diverse group of diseases is initially spotted and subsequently treated in the near future...

Social anhedonia, the reduced capacity for social and interpersonal pleasure, often accompanies several forms of psychopathology. The goal of the present study was to validate the Chinese translation of the Anticipatory and Consummatory Interpersonal Pleasure Scale (ACIPS), a promising new tool for the assessment of individual differences in social pleasure. The Chinese versions of the ACIPS, the Temporal Experience of Pleasure Scale (TEPS), and the Schizotypal Personality Questionnaire (SPQ) were administered to 389 nonclinical adults...

BACKGROUND: The number of cases required to overcome the learning curve (LC) for laparoscopic extra-peritoneal inguinal hernia repair (TEP) varies widely in the literature. Less is known about the LC for inexperienced surgeons performing this procedure early in their career. The present study describes the technical challenges of TEP repair and the LC from the perspective of a recently qualified general surgeon. MATERIALS AND METHODS: Retrospective analysis of a single-surgeon experience of TEP repairs performed during the first 2 y of practice from 2011-2013...

PURPOSE: Seroma is among the most common complications of laparoscopic total extraperitoneal (TEP) for especially large indirect inguinal hernia, and may be regarded as a recurrence by some patients. A potential area localized behind the mesh and extending from the inguinal cord into the scrotum may be one of the major etiological factors of this complication. Our aim is to describe a novel technique in preventing pseudorecurrence by using fibrin sealant to close that potential dead space...
