    In this work, two commercialized anion-exchange membranes (AEMs), AMI-7001 and AF49R27, were applied in microbial electrolysis cells (MECs) and compared with a novel AEM (PSEBS CM DBC, functionalized with 1,4-diazabicyclo[2.2.2]octane) to produce biohydrogen. The evaluation regarding the effect of using different AEMs was carried out using simple (acetate) and complex (mixture of acetate, butyrate and propionate to mimic dark fermentation effluent) substrates. The MECs equipped with various AEMs were assessed based on their electrochemical efficiencies, H2 generation capacities and the composition of anodic biofilm communities. pH imbalances, ionic losses and cathodic overpotentials were taken into consideration together with changes to substantial AEM properties (particularly ion-exchange capacity, ionic conductivity, area- and specific resistances) before and after AEMs were applied in the process to describe their potential impact on the behavior of MECs. It was concluded that the MECs which employed the PSEBS CM DBC membrane provided the highest H2 yield and lowest internal losses compared to the two other separators. Therefore, it has the potential to improve MECs. Vocalizations are an important medium for sexual and social signaling in mammals and birds. In most mammals other than humans, vocalizations are specified by innate mechanisms and develop normally in the absence of auditory experience. By contrast, juvenile songbirds memorize and copy the songs of adult tutors, a process with many parallels to human speech learning. Despite the centrality of vocal learning to human speech, vocal production in humans as well as in songbirds exploits ancestral circuitry for innate vocalizations, and effective vocal communication depends on the fluent blending of innate and learned elements. This review covers recent advances in our understanding of central mechanisms for learned and innate vocalizations in birds and mice, including brainstem mechanisms that help to ‘gate’ vocalizations on or off, cortical involvement in learned and innate vocalizations, and the delineation of circuits that evaluate and reinforce song performance to facilitate vocal learning. The ovipositor morphology of Trichophora (Hemiptera Heteroptera) is revisited. Skeletomuscular structure of the ovipositor of selected species and outgroups is documented. Homologies of the structures are established, different homology hypotheses of previous authors are discussed and rejected. The groundplan of the trichophoran ovipositor is reconstructed, apomorphic conditions of each part of the ovipositor are documented. A standard nomenclature is proposed for muscles associated with the ovipositor and extrinsic muscles of the female inner ectodermal genital tracts. Character transformations of the ovipositor are reconstructed via cladistic analysis. The concepts of “lanceolate ovipositor” and “plate-like ovipositor”, frequently used in the literature, are discussed; it is concluded that no unambiguous definition of them is possible on a morphological basis, these terms refer merely to evolutionary grades rather than strictly distinct character states. “Plate-like ovipositors” evolved at least four times within Trichophora; they exhibit considerable differences among and within these clades. It is demonstrated that the “M- or W-shaped sclerites” of Pyrrhocoridae and Urostylididae are not homologous in Pyrrhocoridae they are expansions of the mesal face of the posterior portion of valvifers IX, whilst the superficially similar structures in Urostylididae are infoldings of the ventral rim of the mesal portion of laterotergites IX. BACKGROUND Dyslexia is a type of specific learning disability (SLD) which has neurobiological origin. It is characterized by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities. The impaired reading in dyslexia is associated with inability to process the sensory input that enters the nervous system. Functional magnetic resonance imaging (fMRI) has emerged as a potential source in understanding the neurobiology and to identify the brain basis of sensory stimuli processed in dyslexic patients. METHODOLOGY The present study was conducted to assess the difference in neural changes using fMRI in children and adolescents with SLD compared with normal children and also the correlation of clinical parameters with BOLD – fMRI changes. Sixteen children and adolescents diagnosed as dyslexia were assessed with All India Institute of Medical Sciences (AIIMS) SLD Battery, Mini-International Neuropsychiatric Interview for Children and Adolescents (MINI KID) and Aggregated Neurobehavioral Student Health and Educational Review (ANSER) system and compared with 15 controls matched with age and sex. Participants of both groups were asked to perform 3 tasks during the fMRI acquisition (phonological, picture-naming and semantic tasks). RESULT As compared to control group, the participants with dyslexia show phonological decoding problem. During picture task, the participants with dyslexia use more areas of brain involve in recalling the memory events while during semantic tasks processing the occipito-temporal (fusiform) gyrus was less activated when in contrast to control. CONCLUSION This study shows that participants with dyslexia fail to use normal brain regions specialized in language processing, but rather use different areas. OSS_128167 cost OBJECTIVE Chinese Americans significantly underutilize mental health resources, which leads to delayed diagnosis, suboptimal management, and can be contributing to the large number of psychiatric emergencies seen in the ED. The goal of this study is to understand the role of using YouTube as a platform for psychiatric emergency outreach among Chinese Americans. METHODS We posted three videos about psychiatric emergencies in Cantonese on YouTube. We collected viewing data during a five-year period. The recorded parameters include watch time, number of views, average view duration, traffic source, search terms, and watch device type. RESULTS The videos generated 40,608 min of watch time and 5976 views, with an average view duration of 6.80 min. The top three traffic sources are YouTube suggested videos, direct YouTube search, and browse features. The three most used viewing devices are mobile phones (25,068 min of watch time, 3491 views, and 7.18 min of average view duration), computer/TV (9222 min of watch time, 1717 views, and 5.
