Individuals with body dysmorphic disorder (BDD) over-attend to perceived defect(s) in their physical appearance, often becoming "stuck" obsessing about perceived flaws and engaging in rituals to hide flaws. These symptoms suggest that individuals with BDD may experience deficits in underlying neurocognitive functions, such as set-shifting and visuospatial organization. These deficits have been implicated as risk and maintenance factors in disorders with similarities to BDD but have been minimally investigated in BDD...

As the leading cause of morbidity and mortality of cystic fibrosis (CF) patients, early detection of Pseudomonas aeruginosa (PA) is critical in the clinical management of this pathogen. Herein, we describe rapid and sensitive electroanalytical methods using differential pulse voltammetry (DPV) at a boron-doped diamond (BDD) electrode for the detection of PA signaling biomolecules. Monitoring the production of key signaling molecules in bacterial cultures of P. aeruginosa PA14 over 8 h is described, involving sample pretreatment by liquid-liquid and solid-phase extraction...

The combination of persulfates (peroxydisulfate (PDS) and peroxymonosulfate (PMS)) and electrolysis using boron-doped diamond (BDD) anode is a promising green advanced oxidation process. In comparison with electrolysis alone, electrochemical activation of persulfates at BDD anode considerably enhanced the degradation of carbamazepine (CBZ). The experimental results indicate that the surface-adsorbed hydroxyl radical (HO) played the dominant role. The generally proposed nonradical oxidation mechanism ignored hydroxyl radical (HO) oxidation because low concentration of radical scavenger (<10 M methanol or 5 M tertbutanol) could not effectively scavenge the surface-adsorbed HO...

The early diagnosis of disease is critical to preventing the occurrence of severe complications. Diabetes is a serious health problem. A variety of methods have been developed for diagnosing diabetes. The majority of these methods have been developed in a black-box manner, which cannot be used to explain the inference and diagnosis procedure. Therefore, it is essential to develop methods with high accuracy and interpretability. In this study, a Reinforcement Learning-based Evolutionary Fuzzy Rule-Based System (RLEFRBS) is developed for diabetes diagnosis...

Belly dancer's dyskinesia (BDD) is an extremely rare manifestation consisting of involuntary and repetitive rhythmic movements of the abdominal wall. These movements cannot be voluntarily suppressed but may be influenced by respiratory maneuvers. Investigations such as spinal cord and abdominal imaging usually fail to reveal any local abnormalities to explain the movement disorder. A 23-year-old male presented with sudden onset of undulating movements of the abdominal wall for the last two months after he took domperidone...

A commercial sulfamethoxazole + trimethoprim formulation has been degraded in 0.050 M Na2SO4 at pH 3.0 by electrochemical oxidation with electrogenerated H2O2 (EO-H2O2), electro-Fenton (EF), photoelectro-Fenton with a 6-W UVA lamp (PEF) and solar photoelectro-Fenton (SPEF). The tests were performed in an undivided cell with an IrO2-based, Pt or boron-doped diamond (BDD) anode and an air-diffusion cathode for H2O2 electrogeneration. The anode material had little effect on the accumulated H2O2 concentration...

Body dysmorphic disorder (BDD) is characterized by excessive preoccupation with a slight or imagined defect in one's physical appearance, believing they look ugly, abnormal or deformed. While the most common preoccupations focus on the skin, hair and nose, any part of the body may be involved. Preoccupations are intrusive, time-consuming and hard to control. Repetitive behaviors are performed in response to the preoccupations. BDD is associated with marked impairment in socio-professional functioning, poor quality of life and high suicide rates...

This study represents the electrooxidation of anti-cancer drug carboplatin (CrbPt) with different mixed metal oxide (MMO) and boron doped diamond (BDD) electrodes. The most effective anode was found as Ti/RuO2 with the complete degradation of CrbPt in just 5min. The effect of applied current density, pH and electrolyte concentration on CrbPt degradation has been studied. The degradation of CrbPt significantly increased at the initial stages of the process with increasing current density. However, further increase in current density did not affect the degradation rate...

T Lahousen, D Linder, T Gieler, U Gieler
People with a body dysmorphic disorder (BDD) suffer from excessive preoccupation and anxiety about an imagined or to others a negligible defect in their appearance. They cannot bear to look at themselves, feel ugly, are convinced that their nose, their physique and their skin are disfiguring. The more concerned they become about their appearance, the more their attention is drawn to the ostensible blemishes and reinforces the impression of their own unattractiveness. Those affected do not consider themselves to be ill, but are convinced that it is a real physical defect which forces them again and again to stand in front of the mirror...

Body dysmorphic disorder (BDD) is characterized by a preoccupation with a perceived defect or flaw in physical appearance that is not observable or appears slight to others. It leads to severe distress and functional impairment. Cognitive-behavioural and neurobiological similarities to obsessive compulsive disorder (OCD) have led to its newly conceived classification as an obsessive compulsive related disorder (OCRD). In the process of investigating the neurobiology of BDD, neuroimaging and neuropsychological studies have been conducted...

OBJECTIVE: Body Dysmorphic Disorder (BDD) is a psychiatric condition characterized by preoccupation with perceived defects in physical appearance that are not observable or appear slight to others, along with low self-esteem, high perfectionism, and high comorbidity. Little is known about BDD prevalence and phenomenology in the Italian context, and no data are currently available on BDD prevalence using DSM-5 criteria in the Italian context. The aims of the current study were to explore the prevalence and the phenomenology of BDD and its associated psychological and psychopathological features such as self-esteem, perfectionistic traits, social anxiety, depressive, and obsessive-compulsive symptoms in a community sample...

Body Dysmorphic Disorder (BDD) is characterized by a preoccupation with a perceived flaw in appearance and repetitive avoidance behaviors. BDD involves severe psychosocial outcomes (e.g., depression, suicidality, functional impairment). Identifying correlates of BDD symptoms and outcomes can inform treatment. Shame, a painful emotion felt in response to critical self-judgment, may be one key correlate. However, research on shame in BDD is scarce and previous studies have not distinguished general shame from body shame...

Much attention has been paid to ways of removing toxic cyanobacteria and cyanotoxins from water prior to its use due to public health concerns. The efficacy of treating the toxic filamentous cyanobacterium Cylindrospermopsis raciborskii (C. raciborskii) by electrolysis with a boron-doped diamond (BDD) in Chloride-free solution was investigated. At optimum current, about 87 and 93% removal of cell density at 60 and 180min and about 72 and 90% of Chl a, respectively. Additionally, a physiological test (FV/Fm) indicated that cells were completely inactivated in 45min...

Body dysmorphic disorder (BDD) is marked by high distress and behavioral and functional impairments due to preoccupation with perceived appearance anomalies. Our aim was to examine parental correlates of offspring's symptoms characteristic of BDD, testing both direct associations and indirect associations via appearance-based rejection sensitivity (appearance-RS). Surveys were completed by 302 Australian adolescents (9-14 years) and their parents. Findings indicated parents' weight and appearance teasing and child-report (but not parent-report) of parental negative attitudes about weight and appearance were uniquely associated with offspring's heightened BDD-like symptoms, and associations were partially indirect via adolescents' appearance-RS...

PURPOSE: To report a new technique called relaxing Descemetotomy for treatment of bullous Descemet detachment (BDD) secondary to accidental hydroseparation of Descemet membrane (DM) during stromal hydration in cataract surgery. METHODS: A clear corneal keratome entry was created close to the limbus extending inward to create a relaxing cut (ab externo relaxing Descemetotomy) on taut DM, thus creating an egress route for supra-Descemetic fluid (SDF). This was followed by pneumodescemetopexy to drain SDF internally...
