The bacterium Raoultella planticola (R planticola) is a rare pathogen in humans. We report a case of mild acute pancreatitis (MAP) of biliary origin with cholangitis and bacteremia with R planticola in association with pancreatic panniculitis (PP). A 55-year-old woman with rheumatic multiple valvulopathy presented with epigastric pain radiating to the back in a belt-like fashion for 48 hours, jaundice, choluria, acholia, and fever (38.2oC). Lab tests showed: amylase 2126 U/L, ALT 124 U/L, AST 169 U/L, GGT 3548 U/L, AP 1516 U/L, TBil 12...

BACKGROUND: Body dysmorphic disorder (BDD) is an often under-recognized yet severe psychiatric illness. There is limited guidance for plastic surgeons in the USA in how to recognize and manage patients with BDD and protect themselves from potential litigation and harm. Therefore, in collaboration with legal counsel, we remind our profession of the serious nature of patients with BDD, provide warning signs for recognizing BDD, and critically evaluate the validity of informed consent and the legal ramifications of operating on such patients in the USA...

The aim of the current study was to establish the prevalence of subthreshold body dysmorphic disorder (subthreshold-BDD) in a community sample of adolescents, and to compare disorder correlates in individuals with subthreshold-BDD to those with probable full-syndrome BDD (probable-BDD) and those without BDD (non-BDD). Self-report questionnaires assessing DSM-IV BDD criteria, past mental health service use, and symptoms of body dysmorphic disorder, anxiety, depression, obsessive-compulsive disorder and eating disorders, were completed by 3149 Australian high school students (mean age =14...

Quantitative studies of electron transfer processes at electrode/electrolyte interfaces, originally developed for homogeneous liquid mercury or metallic electrodes, are difficult to adapt to the spatially heterogeneous nanostructured electrode materials that are now commonly used in modern electrochemistry. In this study, the impact of surface heterogeneity on Fourier-transformed alternating current voltammetry (FTACV) has been investigated theoretically under the simplest possible conditions where no overlap of diffusion layers occurs and where numerical simulations based on a 1D diffusion model are sufficient to describe the mass transport problem...

Yibo Ma, Junsong Liu, Hongdong Li
In this study, we designed and fabricated an electrochemical impedance aptasensor based on Au nanoparticles (Au-NPs) coated boron-doped diamond (BDD) modified with aptamers, and 6-mercapto-1-hexanol (MCH) for the detection of bisphenol A (BPA). The constructed BPA aptasensor exhibits good linearity from 1.0×10(-14) to 1.0×10(-9)molL(-1). The detection limitation of 7.2×10(-15)molL(-1) was achieved, which can be attributed to the synergistic effect of combining BDD with Au-NPs, aptamers, and MCH. The examine results of BPA traces in Tris-HCl buffer and in milk, UV spectra of aptamer/BPA and interference test revealed that the novel aptasensors are of high sensitivity, specificity, stability and repeatability, which could be promising in practical applications...

BACKGROUND: DSM-5 introduced a fundamental revision of the category of somatoform disorders, which resulted in the new somatic symptom disorder (SSD) and related disorders. However, prognostic validity of SSD remains unclear, while other classification proposals, such as bodily distress disorder (BDD) or polysymptomatic distress disorder (PSDD), might be promising alternatives for the new ICD-11. Therefore, the comparison of the different approaches concerning long-term prognosis of disorder-relevant factors is of special interest...

OBJECTIVE: Body dysmorphic disorder (BDD) is characterised by repetitive behaviours and/or mental acts occurring in response to preoccupations with perceived defects or flaws in physical appearance. This study aimed to examine attentional biases in BDD via the emotional Stroop task with two modifications: i) incorporating an eye-tracking paradigm, and ii) employing an obsessive-compulsive disorder (OCD) control group. METHOD: Twenty-one BDD, 19 OCD and 21 HC participants, who were age-, sex-, and IQ-matched, were included...

Álvaro Soriano, Daniel Gorri, Ane Urtiaga
The present study was aimed at the development of a strategy for removing and degrading perfluorohexanoic acid (PFHxA) from industrial process waters at concentrations in the range 60-200 mg L(-1). The treatment train consisted of nanofiltration (NF) separation followed by electrochemical degradation of the NF concentrate. Using a laboratory-scale system and working in the total recirculation mode, the DowFilm NF270 membrane provided PFHxA rejections that varied in the range 96.6-99.4% as the operating pressure was increased from 2...

E Marie Parsons, Kelsey T Straub, April R Smith, Elise M Clerkin
This study tested the potential transdiagnostic nature of body dysmorphic disorder (BDD), obsessive-compulsive disorder (OCD), and social anxiety disorder (SAD) beliefs, in addition to testing the specificity of those beliefs, in predicting how individuals responded to symptom-specific stressors. Participants included 127 adults (75% women) with a broad range of symptom severity. Path analysis was used to evaluate whether specific maladaptive beliefs predicted distress in response to symptom-relevant stressors over and above other beliefs and baseline distress...

Heart transplantation is the therapy of choice for end-stage heart failure. However, hemodynamic instability, which has been demonstrated in brain-dead donors (BDD), could also affect the posttransplant graft function. We tested the hypothesis that treatment of the BDD with the dopamine derivate n-octanoyl-dopamine (NOD) improves donor cardiac and graft function after transplantation. Donor rats were given a continuous intravenous infusion of either NOD (0.882mg/kg/h, BDD+NOD, n=6) or a physiological saline vehicle (BDD, n=9) for 5h after the induction of brain death by inflation of a subdural balloon catheter...

BACKGROUND: Production of recombinant factor VIII (FVIII) is challenging due to its low expression. It was previously shown that codon-optimization of a B domain-deleted FVIII (BDD-FVIII) cDNA resulted in increased protein expression. However, it is well-recognized that synonymous mutations may affect the protein structure and function. OBJECTIVES: To compare biochemical properties of a BDD-FVIII expressed from codon-optimized (CO) and the wild-type (WT) cDNAs. METHODS: Each variant of the BDD-FVIII was expressed in several independent CHO cell lines, generated using a lentiviral platform...

Yuvraj Y Birdja, Marc T M Koper
A seemingly catalytically inactive electrode, boron-doped diamond (BDD), is found to be active for CO2 and CO reduction to formaldehyde and even methane. At very cathodic potentials, formic acid and methanol are formed as well. However, these products are the result of base-catalyzed Cannizzaro-type disproportionation reactions. A local alkaline environment near the electrode surface, caused by the hydrogen evolution reaction, initiates aldehyde disproportionation promoted by hydroxide ions, which leads to the formation of the corresponding carboxylic acid and alcohol...

Nasr Bensalah, Ahmed Bedoui
In this work, the treatment of 4-nitrophenol (NP) in water by ozonation, electrolysis, electro-peroxone (EP), and photo-electro-peroxone (PEP) processes was investigated. PEP process is based on the combination of ozonation, UV irradiation, and electrolysis using carbon felt cathode and Boron Doped Diamond (BDD) anode. In this process, H2O2 is electrochemically generated from reduction of O2 in the ozone generator effluent at a carbon felt cathode. The insitu generated H2O2 is simultaneously decomposed by UV- photolysis and by reaction with O3 to form HO(-) radicals that can rapidly and non-selectively oxidize organic pollutants...

In the present study, the electrochemical oxidation of real wastewaters discharged by textile industry was carried out using a boron-doped diamond (BDD) anode. The effect of operational variables, such as applied current density (20-100 mA·cm(-2)), NaCl concentration added to the real wastewaters (0-3 g·L(-1)), and pH value (2.0-10.0), on the kinetics of COD oxidation and on the energy consumption was carefully investigated. The obtained experimental results could be well matched with a proposed kinetic model, in which the indirect oxidation mediated by electrogenerated strong oxidants would be described through a pseudo-first-order kinetic constant k...

Here, a novel three-level definitive screening design (DSD) was initially employed to investigate the electrochemical degradation of Chromotrope 2R (C2R) with boron-doped diamond (BDD) anodes. Experiments were performed using a synthetic C2R solution containing five supporting electrolytes (Na2SO4, NaCl, Na3PO4, NaNO3 and Na2CO3). The effects of nine quantitative parameters on C2R removal rate: initial C2R concentration (50-100 mg L(-1)), applied current density (1.29-3.87 mA cm(-2)), Na2SO4 concentration (0-10 mM), NaCl concentration (0-10 mM), Na3PO4 concentration (0-10 mM), NaNO3 concentration (0-10 mM), Na2CO3 concentration (0-10 mM), flow rate (300-500 mL min(-1)) and temperature (10-50 °C), were investigated...

Boron-doped diamond (BDD) electrodes are recognized as being superior to other electrode materials due to their outstanding chemical and dimensional stability, their exceptionally low background current, the extremely wide potential window for water electrolysis that they have, and their excellent biocompatibility. However, whereas these properties have been utilized in the rapid development of electroanalytical applications, very few studies have been done in relation to their applications in electrocatalysis or electrosynthesis...

OBJECTIVE: Cognitive behavioral models postulate that selective attention plays an important role in the maintenance of body dysmorphic disorder (BDD). It is suggested that individuals with BDD overfocus on perceived defects in their appearance, which may contribute to the excessive preoccupation with their appearance. METHODS: The present study used eye tracking to examine visual selective attention in individuals with BDD (n=19), as compared to individuals with bulimia nervosa (BN) (n=21) and healthy controls (HCs) (n=21)...
