    BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder targeting skeletal muscle acetylcholine receptor. Thymoma is associated with MG in some patients, the majority of whom present with symptoms of MG before detection of underlying thymoma. This study aimed to study clinical and serological characteristics of Chinese thymomatous MG patients …published_or_final_versio

    Virtual Reality Applications in Rehabilitation

    The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-39510-4_1One of the most valuable applications of virtual reality (VR) is in the domain of rehabilitation. After brain injuries or diseases, many patients suffer from impaired physical and/or cognitive capabilities, such as difficulties in moving arms or remembering names. Over the past two decades, VR has been tested and examined as a technology to assist patients’ recovery and rehabilitation, both physical and cognitive. The increasing prevalence of low-cost VR devices brings new opportunities, allowing VR to be used in practice. Using VR devices such as head-mounted displays (HMDs), special virtual scenes can be designed to assist patients in the process of re-training their brain and reorganizing their functions and abilities. However, such VR interfaces and applications must be comprehensively tested and examined for their effectiveness and potential side effects. This paper presents a review of related literature and discusses the new opportunities and challenges. Most of existing studies examined VR as an assessment method rather than a training/exercise method. Nevertheless, promising cases and positive preliminary results have been shown. Considering the increasing need for self-administered, home-based, and personalized rehabilitation, VR rehabilitation is potentially an important approach. This area requires more studies and research effort

    Dendritic Luminescent Gold(III) Complexes for Highly Efficient Solution-Processable Organic Light-Emitting Devices

    Emission control: carbazole-based dendritic alkynylgold(III) complexes have been evaluated as phosphorescent emitters in organic light-emitting devices. The energy as well as the bathochromic shift of the emissions can be tuned effectively through a control of the dendrimer generation. The optimized devices show high current and external quantum efficiencies of up to 24.0 cd A(-1) and 7.8 %, respectively. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

    Embryonic Disruption Of The Candidate Dyslexia Susceptibility Gene Homolog Kiaa0319-like Results In Neuronal Migration Disorders.

    Developmental dyslexia, the most common childhood learning disorder, is highly heritable, and recent studies have identified KIAA0319-Like (KIAA0319L) as a candidate dyslexia susceptibility gene at the 1p36-34 (DYX8) locus. In this experiment, we investigated the anatomical effects of knocking down this gene during rat corticogenesis. Cortical progenitor cells were transfected using in utero electroporation on embryonic day (E) 15.5 with plasmids encoding either: (1) Kiaa0319l shRNA, (2) an expression construct for human KIAA0319L, (3) Kiaa0319l shRNA + KIAA0319L expression construct (rescue), or (4) controls (scrambled Kiaa0319l shRNA or empty expression vector). Mothers were injected with BrdU at either E13.5, E15.5, or E17.5. Disruption of Kiaa0319l function (by knockdown, overexpression, or rescue) resulted in the formation of large nodular periventricular heterotopia in approximately 25% of the rats, and these heterotopia can be seen as early as postnatal day 1. Only a small subset of heterotopic neurons had been transfected, indicating non-cell autonomous effects of the transfection. Most heterotopic neurons were generated in mid- to late-gestation, and laminar markers suggest that they were destined for upper cortical laminæ. Finally, we found that transfected neurons in the cerebral cortex were located in their expected laminæ. These results indicate that KIAA0319L is the fourth of four candidate dyslexia susceptibility genes that is involved in neuronal migration, which supports the association of abnormal neuronal migration with developmental dyslexia

    Virtual Reality and Psychotic Disorders

    In the early years of virtual reality in mental healthcare several reviews were published (Gregg and Tarrier 2007; G. Riva 2002; 2003; 2005). None of them mentions work done on virtual reality with psychotic disorders yet, though some early work was starting to get published around the same time. There are different psychotic disorders with each their own specified combination of symptom domains, symptom intensity and duration. Wood et al. (2011) suggest a dimensional staging of psychosis, ranging from psychotic-like experiences to severe persistent psychotic episodes. A large body of research is accumulating showing psychotic symptoms can be seen as a transdiagnostic and extended phenotype found in the general population (J. van Os and Reininghaus 2016). When psychotic experiences persist, transition to a psychotic disorder becomes a possibility. The main recognizable symptom domains of psychotic disorders are hallucinations and delusions. Hallucinations are perceptions a person experiences without a corresponding external stimulus. Hallucinations can occur for all five senses. Patients with a psychotic disorder for example often experience auditory hallucinations such as hearing voices. These voices can be commentary, give orders to the patient or call them names. Delusions are beliefs people have about the external reality which are strongly maintained despite strong evidence to the contrary or despite what almost everybody else (of a person’s culture or subculture) believes. The most common delusion found in psychotic disorders is the persecutory delusion (paranoia). People with a persecutory delusion feel others (known or unknown) spy on them, pursue them and threaten their safety (van der Gaag et al. 2012; Beck et al. 2009). Hallucinations and delusions often cause anxiety and make the patient avoid (social) situations, which can be treated with exposure therapy. Other symptom domains of psychotic disorders are negative symptoms and impaired cognition. Patients with negative symptoms experience an diminished emotional expression and avolition. Impaired cognition is about learning deficiencies, whether insufficiently thought or thwarted by deficits. For both negative symptoms and impaired cognition training can help patients learn to master new skills. There are some additional symptom domains in psychotic disorders, but these don’t play a part in virtual reality (yet).
