dentify previously unknown interactions between insulin receptor activation, opioids, and glutamatergic transmission. These data contribute to our fundamental understanding of insulin's influence on brain motivational systems and have implications for the use of insulin as a cognitive enhancer and for targeting of insulin receptors and IGF receptors to alter motivation.Why layers II/III of entorhinal cortex (EC) deteriorate in advance of other regions during the earliest stages of Alzheimer's disease is poorly understood. Failure of retrograde trophic support from synapses to cell bodies is a common cause of neuronal atrophy, and we accordingly tested for early-life deterioration in projections of rodent layer II EC neurons. Using electrophysiology and quantitative imaging, changes in EC terminals during young adulthood were evaluated in male rats and mice. Field excitatory postsynaptic potentials, input/output curves, and frequency following capacity by lateral perforant path (LPP) projections from lateral EC to dentate gyrus were unchanged from 3 to 8-10 months of age. In contrast, the unusual presynaptic form of long-term potentiation (LTP) expressed by the LPP was profoundly impaired by 8 months in rats and mice. This impairment was accompanied by a reduction in the spine to terminal endocannabinoid signaling needed for LPP-LTP induction and was offset by an agent that 8-10 months of age. Moreover, there was a substantial decline in the performance of an episodic memory task that depends on entorhinal cortical projections at the same ages. Overall, the results suggest that the loss of plasticity and related trophic signaling predispose the entorhinal neurons to functional decline in relatively young adulthood.In humans, the occipital middle-temporal region (hMT+/V5) specializes in the processing of visual motion, while the planum temporale (hPT) specializes in auditory motion processing. It has been hypothesized that these regions might communicate directly to achieve fast and optimal exchange of multisensory motion information. Here we investigated, for the first time in humans (male and female), the presence of direct white matter connections between visual and auditory motion-selective regions using a combined fMRI and diffusion MRI approach. https://www.selleckchem.com/products/rmc-9805.html We found evidence supporting the potential existence of direct white matter connections between individually and functionally defined hMT+/V5 and hPT. We show that projections between hMT+/V5 and hPT do not overlap with large white matter bundles, such as the inferior longitudinal fasciculus and the inferior frontal occipital fasciculus. Moreover, we did not find evidence suggesting the presence of projections between the fusiform face area and hPT, supporting the functionchange and integration of multisensory motion information. These findings suggest the existence of computationally specific pathways that allow information flow between areas that share a similar computational goal.In Caenorhabditis elegans, axon regeneration is activated by a signaling cascade through the receptor tyrosine kinase (RTK) SVH-2. Axonal injury induces svh-2 gene expression by degradation of the Mad-like transcription factor MDL-1. In this study, we identify the svh-24/sdz-33 gene encoding a protein containing F-box and F-box-associated domains as a regulator of axon regeneration in motor neurons. We find that sdz-33 is required for axon injury-induced svh-2 expression. SDZ-33 targets MDL-1 for poly-ubiquitylation and degradation. Furthermore, we demonstrate that SDZ-33 promotes axotomy-induced nuclear degradation of MDL-1, resulting in the activation of svh-2 expression in animals. These results suggest that the F-box protein is required for RTK signaling in the control of axon regeneration.SIGNIFICANCE STATEMENT In Caenorhabditis elegans, axon regeneration is positively regulated by the growth factor SVH-1 and its receptor tyrosine kinase SVH-2. Expression of the svh-2 gene is induced by axonal injury via the Ets-like transcription factor ETS-4, whose transcriptional activity is inhibited by the Mad-like transcription factor MDL-1. Axon injury leads to the degradation of MDL-1, and this is linked to the activation of ETS-4 transcriptional activity. In this study, we identify the sdz-33 gene encoding a protein containing an F-box domain as a regulator of axon regeneration. We demonstrate that MDL-1 is poly-ubiquitylated and degraded through the SDZ-33-mediated 26S proteasome pathway. These results reveal that an F-box protein promotes axon regeneration by degrading the Mad transcription factor. Although patient-reported outcome measures (PROMs) are increasingly used in clinical practice and research, it is unclear whether these instruments cover the perspective of young people with inflammatory arthritis (IA). The aims of this study were to explore whether PROMs commonly used in IA adequately cover the perspective of young people from different European countries. A multinational qualitative study was conducted in Austria, Croatia, Italy and the Netherlands. Young people with either rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), Still's disease, psoriatic arthritis (PsA) or spondyloarthritis (SpA), aged 18-35 years, participated in semistructured focus group interviews. Thematic analysis was used and data saturation was defined as no new emergent concepts in at least three subsequent focus groups. Fifty-three patients (21 with RA/JIA/Still's, 17 with PsA, 15 with SpA; 72% women) participated in 12 focus groups. Participants expressed a general positive attitude towards PROMs and emphasised their importance in clinical practice. In addition, 48 lower level concepts were extracted and summarised into 6 higher level concepts describing potential issues for improvement. These included need for lay-term information regarding the purpose of using PROMs; updates of certain outdated items and using digital technology for data acquisition. Some participants admitted their tendency to rate pain, fatigue or disease activity differently from what they actually felt for various reasons. Despite their general positive attitude, young people with IA suggested areas for PROM development to ensure that important concepts are included, making PROMs relevant over the entire course of a chronic disease.
