    Abstract Following introduction of the monoamine oxidase type B inhibitor selegiline for the treatment of Parkinson's disease (PD), discovery of the action mechanism of Alzheimer's disease-modifying agent memantine, the role of iron in PD, and the loss of electron transport chain complex I in PD, and development of the concept of clinical neuroprotection, Peter Riederer launched one of the most challenging research project neurodevelopmental aspects of neuropsychiatric disorders. The neurodevelopmental theory holds that a disruption of normal brain development in utero or during early life underlies the subsequent emergence of neuropsychiatric symptoms during later life. Indeed, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and the International Classification of Diseases, 11th Revision categorize autism spectrum disorder and attention deficit hyperactivity disorder in neurodevelopmental disorders (NDDs). More and more evidence, especially from preclinical studies, is revealing that neurodevelopmental pathology is not limited to the diagnostic class above, but also contributes to the development of other psychiatric disorders such as schizophrenia, bipolar disorder, and obsessive-compulsive disorder as well as neurodegenerative diseases such as PD and Huntington's disease. Preclinical animal research is taking a lead in understanding the pathomechanisms of NDDs, searching for novel targets, and developing new neuroprotective agents against NDDs. This narrative review discusses emerging evidence of the neurodevelopmental etiology of neuropsychiatric disorders, recent advances in modelling neurodevelopmental pathogenesis, potential strategies of clinical neuroprotection using novel kynurenine metabolites and analogues, and future research direction for NDDs.

    Title translation The role of PET/CT in the central nervous system tumours.
    Abstract The appearance of hybrid imaging, including PET/CT has been a huge milestone not only in the development of nuclear medicine but of the whole medical imaging. The examination with 18F-FDG, the most frequently used radiopharmaceutical has become for now one of the most important diagnostic tools in oncological patient care, applied with numerous indication goals. However, the depiction of central nervous system malignancies, especially those of the brain, with FDG PET has limitations due to high cerebral background activity, it can be used primarily in lymphoma cases. To evaluate gliomas and brain metastases, amino acid tracers (11C-methionine, 18F-DOPA and 18F-FET) gained ground, which reflect other biological processes compared to that of FDG. Upon multiplying of evidences their usage is becoming more and more diverse, from the primary assessment of brain tumours (benign vs. malignant), through their grading and evaluation of posttherapeutical viability/recurrence, up to the radiotherapy planning. This paper reviews all of these in more details, mentioning shortly the prospects and challenges of the future.

    Abstract During melt-processing, the molecular weight of poly(ethylene terephthalate) PET, being prone to hydrolytic degradation, decreases proportionally with its initial moisture content. Therefore, to avoid undesired deterioration of the physical and mechanical properties, PET granules or recyclates are generally dried (the residual moisture must be generally lower than 500 ppm) just prior to melt-processing. In this research, in contrast to the general practice, PET granules with increasing moisture content in the range of 30-3520 ppm, as conditioned in a climate chamber, were melt blended with a constant amount (13%) of ethylene-butyl acrylate-glycidyl methacrylate (EBA-GMA) type reactive terpolymer by twin screw extrusion. It was found that moisture boosts the reactive toughening process, and consequently, the notched Izod impact strength increases by up to 600%. Notched impact strength higher than 50 kJ/m² was reached only by using PET with optimal (1710 ppm) moisture level instead of fully dried granules, as starting material. It is also noteworthy that the tensile strength and stiffness of the blends showed little variation over the examined moisture content range. Scanning electron microscopic analyses show that the size of the dispersed phase decreases continuously with the increasing initial moisture content of PET, which is explained by the increasingly effective interfacial compatibilisation with the terpolymer. Compatibilisation reactions are accelerated by the low-molecular-weight PET chains of increased reactivity that are formed in situ in the presence of moisture during melt-processing. The observed phenomenon can be advantageously utilized for upgrading recycling technology.

    Abstract Tissue-resident memory T cells (TRM) represent a dedicated layer of localized immune memory in virtually every organ throughout the human body. By virtue of their long-term residence in disparate tissues, TRM are shaped by a myriad of site-specific influences and exhibit remarkable heterogeneity in form and function. Here, we review the major axes by which TRM vary, including their surface phenotypes, transcriptional programming, and the tissue-specific adaptations that accrue over their tenancy. We discuss how localization within distinct anatomic niches both within and across major organ systems shapes TRM identity and examine mechanisms and prevailing models for TRM generation. Understanding the drivers of differentiation, function and maintenance of the various subpopulations that together define the TRM lineage may hold the key to unlocking the full potential of TRM to promote localized and protective tissue immunity throughout the body.

    Abstract The FERM domain is a conserved and widespread protein module that appeared in the common ancestor of amoebae, fungi, and animals, and is therefore now found in a wide variety of species. The primary function of the FERM domain is localizing to the plasma membrane through binding lipids and proteins of the membrane; thus, for a long time, FERM domain-containing proteins (FDCPs) were considered exclusively cytoskeletal. Although their role in the cytoplasm has been extensively studied, the recent discovery of the presence and importance of cytoskeletal proteins in the nucleus suggests that FDCPs might also play an important role in nuclear function. In this review, we collected data on their nuclear localization, transport, and possible functions, which are still scattered throughout the literature, with special regard to the role of the FERM domain in these processes. With this, we would like to draw attention to the exciting, new dimension of the role of FDCPs, their nuclear activity, which could be an interesting novel direction for future research.
