The definitions of most of the currently recognized neurodevelopmental disorders and the criteria used to identify them have seen important changes since their inclusion in diagnostic classification systems (see, for instance, how the definitions of specific learning disorders and autism spectrum disorder (ASD) have been revised in successive versions of DSM). As is the case with many other mental conditions, our understanding of neurodevelopmental disorders is continuously being updated in the light of new research findings. However, this has not been the case for nonverbal learning disability. More than 50 years since it was first described,1 there is still no consensus on the merits of identifying it as a separate disorder or using a clear and acknowledged diagnostic label. Instead of trying to establish why nonverbal learning disability has yet to be included in the diagnostic manuals, this editorial examines why recognized criteria for the condition would improve research in this field and avoid the negative consequences of continuing to conduct research without adopting shared criteria.Nipah virus (NiV) and Hendra virus (HeV) are highly pathogenic, bat-borne paramyxoviruses in the genus Henipavirus that cause severe and often fatal acute respiratory and/or neurologic diseases in humans and livestock. BVD-523 datasheet There are currently no approved antiviral therapeutics or vaccines for use in humans to treat or prevent NiV or HeV infection. To facilitate development of henipavirus antivirals, a high-throughput screening (HTS) platform was developed based on a well-characterized recombinant version of the nonpathogenic Henipavirus, Cedar virus (rCedV). Using reverse genetics, a rCedV encoding firefly luciferase (rCedV-Luc) was rescued and its utility evaluated for high-throughput antiviral compound screening. The luciferase reporter gene signal kinetics of rCedV-Luc in different human cell lines was characterized and validated as an authentic real-time measure of viral growth. The rCedV-Luc platform was optimized as an HTS assay that demonstrated high sensitivity with robust Z' scores, excellent signal-to-background ratios and coefficients of variation. Eight candidate compounds that inhibited rCedV replication were identified for additional validation and demonstrated that 4 compounds inhibited authentic NiV-Bangladesh replication. Further evaluation of 2 of the 4 validated compounds in a 9-point dose response titration demonstrated potent antiviral activity against NiV-Bangladesh and HeV, with minimal cytotoxicity. This rCedV reporter can serve as a surrogate yet authentic BSL-2 henipavirus platform that will dramatically accelerate drug candidate identification in the development of anti-henipavirus therapies.Fluid interfaces, i.e. the boundary layer of two liquids or a liquid and a gas, play a vital role in physiological processes as diverse as visual perception, oral health and taste, lipid metabolism, and pulmonary breathing. These fluid interfaces exhibit a complex composition, structure, and rheology tailored to their individual physiological functions. Advances in interfacial thin film techniques have facilitated the analysis of such complex interfaces under physiologically relevant conditions. This allowed new insights on the origin of their physiological functionality, how deviations may cause disease, and has revealed new therapy strategies. Furthermore, the interactions of physiological fluid interfaces with exogenous substances is crucial for understanding certain disorders and exploiting drug delivery routes to or across fluid interfaces. Here, we provide an overview on fluid interfaces with physiological relevance, namely tear films, interfacial aspects of saliva, lipid droplet digestion and storage in the cell, and the functioning of lung surfactant. We elucidate their structure-function relationship, discuss diseases associated with interfacial composition, and describe therapies and drug delivery approaches targeted at fluid interfaces. STATEMENT OF SIGNIFICANCE Fluid interfaces are inherent to all living organisms and play a vital role in various physiological processes. Examples are the eye tear film, saliva, lipid digestion & storage in cells, and pulmonary breathing. These fluid interfaces exhibit complex interfacial compositions and structures to meet their specific physiological function. We provide an overview on physiological fluid interfaces with a focus on interfacial phenomena. We elucidate their structure-function relationship, discuss diseases associated with interfacial composition, and describe novel therapies and drug delivery approaches targeted at fluid interfaces. This sets the scene for ocular, oral, or pulmonary surface engineering and drug delivery approaches.This mini-review is a short overview of different therapeutical strategies targeting B cells in systemic autoimmune rheumatic diseases, mainly rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and primary Sjogren Syndrome (pSS). Many strategies and their rationale are discussed in this review B cells' depletion (anti-CD20, anti-CD22), long-lived plasma cells depletion (anti-CD19, anti-CD27, anti-CD38 and anti-CD138), changing activation of B cells (anti-BAFF) and inhibiting proteasomes in plasma cells (bortezomib). The past successful therapies and less successful are shown, and the possible reasons for failures are discussed.Growing evidence suggests that both the medial prefrontal cortex (mPFC) and the subthalamic nucleus (STN) play crucial roles in conflict processing, but how these two structures coordinate their activities remains poorly understood. We simultaneously recorded electroencephalogram from the mPFC and local field potentials from the STN using deep brain stimulation electrodes in 13 Parkinson's disease patients while they performed a Stroop task. Both mPFC and STN showed significant increases in theta activities (2-8 Hz) in incongruent trials compared to the congruent trials. The theta activity in incongruent trials also demonstrated significantly increased phase synchronization between mPFC and STN. Furthermore, the amplitude of gamma oscillation was modulated by the phase of theta activity at the STN in incongruent trials. Such theta-gamma phase-amplitude coupling (PAC) was much stronger for incongruent trials with faster reaction times than those with slower reaction times. Elevated theta-gamma PAC in the STN provides a novel mechanism by which the STN may operationalize its proposed "hold-your-horses" role.
