Chunyong Zhang, Jiahui Xian, Min Liu, Degang Fu
In this research, the brominated oligomers formed during phenol degradation with boron-doped diamond (BDD) anode had been initially studied at three different concentrations of bromide (1, 10 and 100mM). The results from LC/MS analysis indicated that, brominated monomer, dimer and trimer of phenols resulting from electrophilic substitution and coupling reactions were the important reaction by-products. Specifically, the trimer by-products were generated only in bromide-rich systems. The reaction mechanisms concerning oligomer formations were proposed in detail accordingly...

There has been an increase in neuroimaging research in body dysmorphic disorder (BDD), yet little is known about the underlying neurobiological basis of the disorder. We aimed to provide a systematic overview of the literature on the neurobiology of BDD. Two reviewers undertook a search of three electronic research databases: PubMed, PsycINFO, and Google Scholar. The search consisted of synonyms commonly associated with BDD and methods to evaluate brain structure, function, and network organisation. Out of an initial yield of 175 articles, 19 fulfilled inclusion criteria and were reviewed...

Boron-doped diamond (BDD) has attracted much attention as a promising electrode material especially for electrochemical sensing systems, because it has excellent properties such as a wide potential window and low background current. It is known that the electrochemical properties of BDD electrodes are very sensitive to the surface termination such as to whether it is hydrogen- or oxygen-terminated. Pretreating BDD electrodes by cathodic reduction (CR) to hydrogenate the surface has been widely used to achieve high sensitivity...

A polycrystalline diamond electrolyte-solution-gate field-effect transistor (BDD-SGFET) was successfully applied to the analysis of water content in ethanol. Due to the use of a no-gate-insulator FET, the developed sensor showed a four-times-faster response than the conventional Si-FET, and a ten-times-faster response than a glass electrode. The output voltage showed good linearity with respect to the water content. This result is of practical importance because the traditional water content measurement methods are impractical due to their slow response...

We developed methods to use synthesized boron-doped diamond (BDD) as a heater in a multi-anvil high-pressure apparatus. The synthesized BDD heater could stably generate an ultra-high temperature without the issues (anomalous melt, pressure drop, and instability of heating) arising from oxidation of boron into boron oxide and graphite-diamond conversion. We synthesized BDD blocks and tubes with boron contents of 0.5-3.0 wt. % from a mixture of graphite and amorphous boron at 15 GPa and 2000 °C. The electrical conductivity of BDD increased with increasing boron content...

BACKGROUND: Individuals with body dysmorphic disorder (BDD) are highly distressed and impaired owing to perceived defects in their physical appearance that are not noticeable to others. They are frequently concerned about their skin and often present to dermatologists rather than psychiatrists. However, BDD patients attending dermatology clinics may be at risk of not receiving an appropriate assessment and beneficial treatment. The aims of this study were to estimate the BDD prevalence rate among Swedish female dermatology patients and to assess the psychological condition of BDD patients compared to that of other dermatology patients...

PURPOSE: Surgical outcome is influenced by multiple patient-specific factors and operative expertise of the surgeon. Clinical relevance of medical technical innovations often remains unclear even though laparoscopic surgical procedures are characterized by continual advancement of various devices. Lately, in dissection and sealing technology, fast-cutting ultrasonic scissors are combined with simultaneous bipolar coagulation (bimodal dissection device (BDD)). We investigated how this new technology, operative expertise, and patient-specific factors (body mass index, age) influence operation time in laparoscopic-assisted sigmoid resection...

The capacity of the photo electro-Fenton (PEF) process to degrade a mixture of seven polychlorinated biphenyl (PCB) congeners (PCB28, PCB52, PCB101, PCB138, PCB153, PCB180 and PCB209), each at an initial concentration of 50 µg L(-1), was studied. Boron-doped diamond (BDD) sheets were used as anode and cathode in the experimental electrolytic cell that contained Na2SO4 0.05 M at pH 3 as supporting electrolyte for the electro generation of H2O2 at the cathode. The effects of UV light intensity (254 and 365 nm), current density (8, 16 and 24 mA cm(-2)) and the initial concentration of the ferrous ion (0...

BACKGROUND: Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created 'obsessive-compulsive and related disorders' chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models. METHODS: Self-report questionnaires assessing disorder symptoms were completed by 3149 Australian adolescents...

Atrazine (ATZ) is one of the most common pesticides detected in surface water in Quebec (Canada). The present study was mainly focused on the degradation of ATZ and its by-products using electrochemical advanced oxidation processes such as photo-electro-Fenton (PEF), electro-Fenton (EF) and anodic-oxidation with simultaneous H2O2 formation (AO - H2O2). The comparison of these processes showed that PEF process was found to be the most effective process in removing ATZ and its by-products from both synthetic solution (ATZ0 = 100 μg L(-1)) and real agricultural surface water enriched with ATZ (ATZ0 = 10 μg L(-1))...

OBJECTIVE: Previous studies investigated predictors of repetitive transcranial magnetic stimulation (rTMS) response in depressive disorders but there is still limited knowledge about clinical predictors. Moreover, predictors of rTMS response in bipolar depression (BDD) are less studied than unipolar depression (UDD). METHODS: We performed a binary logistic regression analysis in 248 patients with depressive disorders (unipolar N=102, bipolar N=146) who received 20 sessions of DLPFC rTMS (High-frequency rTMS, low-frequency rTMS, bilateral rTMS) to investigate significant clinical and demographic predictors of rTMS response...

Boron-doped diamond (BDD) has superior electrochemical properties for bioelectronic systems. However, due to its high synthesis temperature, traditional microfabrication methods have limits to integrating BDD with emerging classes of flexible, polymer-based bioelectronic systems. This paper introduces a novel fabrication solution to this challenge, which features (i) a wafer-scale substrate transfer process with all diamond structures transferred onto a flexible Parylene-C substrate and (ii) Parylene anchors introduced to strengthen the bonding between BDD and Parylene substrates, as demonstrated by a peeling test...

The use of performance and image enhancing drugs (PIEDs) is not uncommon in athletes and appears to be associated with several psychopathological disorders of unclear prevalence. In this multicenter, cross-sectional study, we aimed to evaluate the prevalence of body image disorders (BIDs) and eating disorders (EDs) in PIED-using athletes vs. PIED nonusers. We enrolled 84 consecutive professional and amateur athletes training in sport centers in Italy, who underwent semi-structured interviews (SCID-I, SCID-II) and completed the Body Image Concern Inventory (BICI) and the Sick, Control, One, Fat, Food Eating Disorder Screening Test (SCOFF)...

Background The body dysmorphic disorder (BDD) is considered to be a sub-form of somatoform disorders. BDD can express itself in a delirious experience, an excessive evaluation and employment of the external appearance, in particular the face. Preliminary results suggest that individuals with BDD do not benefit from plastic surgery, so that aesthetic surgery often results in aggravation of their symptoms. Thus, the identification of signs for a BDD is crucial, whether a patient should be operated plastically-aesthetically...

Pralay Gayen, Brian P Chaplin
This research investigated the effects of surface fluorination on both rates of organic compound oxidation (phenol and terephthalic acid (TA)) and ClO4(-) formation at boron-doped diamond (BDD) film anodes at 22 °C. Different fluorination methods (i.e., electrochemical oxidation with perfluorooctanoic acid (PFOA), radio frequency plasma, and silanization) were used to incorporate fluorinated moieties on the BDD surface, which was confirmed by X-ray photoelectron spectroscopy (XPS). The silanization method was found to be the most effective fluorination method using a 1H,1H,2H,2H-perfluorodecyltrichlorosilane precursor to form a self-assembled monolayer (SAM) on the oxygenated BDD surface...

The objective of this study was to investigate the removal efficiencies of the electrochemical treatment systems as an alternative for the treatment of cardboard plant wastewater (CPW). In accordance with this purpose, CPW was treated by electrocoagulation (EC) with Al electrodes and the effects of current density (CD), operating time (t), and initial pH (pHi) were investigated. The results showed that EC at optimum treatment conditions (CD: 7.5mA/cm(2), pHi: 7.0 and t: 60min) have limited removal efficiencies for total organic carbon (TOC; 17...

Body dysmorphic disorder (BDD) is a relatively common and disabling psychiatric disorder characterised by excessive and persistent preoccupation with perceived defects or flaws in one's appearance, which are unnoticeable to others, and associated repetitive behaviours (eg, mirror checking). The disorder generally starts in adolescence, but often goes unnoticed and is severely underdiagnosed. Left untreated, BDD typically persists and causes marked functional impairment in multiple domains. This clinical review considers recent advances in the epidemiology and classification of BDD, including its reclassification in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders under the new 'Obsessive-Compulsive and Related Disorders' chapter...

Detecting the bio-potential changes of plants would be useful for monitoring their growth and health in the field. A sensitive plant monitoring system with flexible boron-doped diamond (BDD) electrodes prepared from BDD powder and resin (Nafion or Vylon-KE1830) was investigated. The properties of the electrodes were compared with those of small BDD plate-type electrodes by monitoring the bioelectric potentials of potted Aloe and hybrid species in the genus Opuntia. While flexible BDD electrodes have wide potential windows, their cyclic voltammograms are different from those of the BDD plate...
