Autosomal dominant polycystic kidney disease (ADPKD) is a common monogenic disorder, characterized by bilateral renal cyst formation. Multiple pathways are de-regulated in cystic epithelia offering good opportunities for therapy. Others and we have previously reported that metabolic reprogramming, including alterations of the TCA cycle, are prominent features of ADPKD. Several lines of evidence suggest that mitochondrial impairment might be responsible for the metabolic alterations. Here, we performed morphologic and morphometric evaluation of mitochondria by TEM in an orthologous mouse model of PKD caused by mutations in the Pkd1 gene (Ksp-Cre;Pkd1flox/- ). Furthermore, we measured mitochondrial respiration by COX and SDH enzymatic activity in situ. We found several alterations including reduced mitochondrial mass, altered structure and fragmentation of the mitochondrial network in cystic epithelia of Ksp-Cre;Pkd1flox/- mice. At the molecular level, we found reduced expression of the pro-fusion proteins OPA1 and MFN1 and up-regulation of the pro-fission protein DRP1. Importantly, administration of Mdivi-1, which interferes with DRP1 rescuing mitochondrial fragmentation, significantly reduced kidney/body weight, cyst formation, and improved renal function in Ksp-Cre;Pkd1flox/- mice. Our data indicate that impaired mitochondrial structure and function play a role in disease progression, and that their improvement can significantly modify the course of the disease. © 2020 IRCCS Ospedale San Raffaele.

METHODS We performed a systematic review and meta-analysis of randomized controlled trials of surgical treatment of supratentorial spontaneous intracerebral hemorrhage aimed at clot removal. We searched MEDLINE, Embase and Cochrane databases up to February 21st , 2019. Primary outcome was good functional outcome at follow-up; secondary outcomes were death and serious adverse events. We analyzed all types of surgery combined and minimally invasive approaches separately. We pooled risk ratios with 95% confidence intervals and assessed the modifying effect of age, Glasgow Coma Scale, hematoma volume and timing of surgery with meta-regression analysis. RESULTS We included 21 studies with 4145 patients; four (19%) were of the highest quality. Risk ratio of good functional outcome after any type of surgery was 1.40 (95% confidenceopyright.

These findings emerge from studies conducted within a single experimental session, preventing the possibility of disentangling short-term from long-term habituation effects. The present study investigated whether affective habituation reflects a short-living learning process, or a more stable change involving long-term memory. learn more Participants went through a first habituation phase consisting of 80 repetitions of the same set of emotional and neutral pictures, when event-related potentials and oscillatory activity were measured (Session 1). Crucially, after a 1-day interval, the same participants were exposed to a second habituation phase with the same stimuli that had been seen before. Results showed that the attenuation of the late positive potential (LPP) affective modulation prompted throughout repetitions of Session 1 remained unchanged after a 1-day interval, and this between-session habituation effect, which was specific to repeated exemplars, was consistent across different emotional contents. Alpha desynchronization was clearly enhanced for pictures of erotica and mutilation and this modulatory pattern remained fairly stable over repetitions. Altogether, these findings suggest that LPP affective habituation is not a short-living learning process, but, rather, reflects a strengthened long-term memory representation of specific repeated stimuli. © 2020 Society for Psychophysiological Research.The prenatal and early postnatal stages represent a critical time window for human brain development. Interestingly, this window partly overlaps with the maturation of the intestinal flora (microbiota) that play a critical role in the bidirectional communication between the central and the enteric nervous systems (microbiota-gut-brain axis). The microbial composition has important influences on general health and the development of several organ systems, such as the gastrointestinal tract, the immune system, and also the brain. Clinical studies have shown that microbiota alterations are associated with a wide range of neuropsychiatric disorders including autism spectrum disorder, attention deficit hyperactivity disorder, schizophrenia, and bipolar disorder. In this review, we dissect the link between these neuropsychiatric disorders and the intestinal microbiota by focusing on their effect on synaptic pruning, a vital process in the maturation and establishing efficient functioning of the brain. We discuss in detail how synaptic pruning is dysregulated differently in the aforementioned neuropsychiatric disorders and how it can be influenced by dysbiosis and/or changes in the intestinal microbiota composition. We also review that the improvement in the intestinal microbiota composition by a change in diet, probiotics, prebiotics, or fecal microbiota transplantation may play a role in improving neuropsychiatric functioning, which can be at least partly explained via the optimization of synaptic pruning and neuronal connections. Altogether, the demonstration of the microbiota's influence on brain function via microglial-induced synaptic pruning addresses the possibility that the manipulation of microbiota-immune crosstalk represents a promising strategy for treating neuropsychiatric disorders. © 2020 The Authors.
