Influences of Sex, Education, and Country of Birth on Clinical Presentations and Overall Outcomes of Interdisciplinary Pain Rehabilitation in Chronic Pain Patients: A Cohort Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP).
Journal of clinical medicine, 2020

This study investigates the effects of sex, education, and country of birth on clinical presentations and outcomes of interdisciplinary multimodal pain rehabilitation programs (IMMRPs). A multivariate improvement score (MIS) and two retrospective estimations of changes in pain and ability to handle life situations were used as the three overall outcomes of IMMRPs. The study population consisted of chronic pain patients within specialist care in the Swedish Quality Registry for Pain Rehabilitation (SQRP) between 2008 and 2016 at baseline (n = 39,916), and for the subset participating in IMMRPs (n = 14,666). A cluster analysis based on sex, education, and country of origin revealed significant differences in the following aspects: best baseline clinical situation was for European women with university educations and the worst baseline clinical situation was for all patients born outside Europe of both sexes and different educations (i.e., moderate-large effect sizes). In addition, European women with university educations also had the most favorable overall outcomes in response to IMMRPs (small effect sizes). These results raise important questions concerning fairness and equality and need to be considered when optimizing assessments and content and delivery of IMMRPs for patients with chronic pain.
Revealing architectural order with quantitative label-free imaging and deep learning.
eLife, 2020

We report quantitative label-free imaging with phase and polarization (QLIPP) for simultaneous measurement of density, anisotropy, and orientation of structures in unlabeled live cells and tissue slices. We combine QLIPP with deep neural networks to predict fluorescence images of diverse cell and tissue structures. QLIPP images reveal anatomical regions and axon tract orientation in prenatal human brain tissue sections that are not visible using brightfield imaging. We report a variant of U-Net architecture, multi-channel 2.5D U-Net, for computationally efficient prediction of fluorescence images in three dimensions and over large fields of view. Further, we develop data normalization methods for accurate prediction of myelin distribution over large brain regions. We show that experimental defects in labeling the human tissue can be rescued with quantitative label-free imaging and neural network model. We anticipate that the proposed method will enable new studies of architectural order at spatial scales ranging from organelles to tissue.
Fatal Status Epilepticus in Dravet Syndrome.
Brain sciences, 2020

Dravet Syndrome (DS) is burdened by high epilepsy-related premature mortality due to status epilepticus (SE). We surveyed centres within Europe through the Dravet Italia Onlus and EpiCARE network (European Reference Network for Rare and Complex Epilepsies). We collated responses on seven DS SCN1A+ patients who died following refractory SE (mean age 6.9 year, range 1.3-23.4 year); six were on valproate, clobazam, and stiripentol. All patients had previous SE. Fatal SE was always triggered by fever: either respiratory infection or one case of hexavalent vaccination. SE lasted between 80 min and 9 h and all patients received IV benzodiazepines. Four patients died during or within hours of SE; in three patients, SE was followed by coma with death occurring after 13-60 days. Our survey supports the hypothesis that unresponsive fever is a core characteristic feature of acute encephalopathy. We highlight the need for management protocols for prolonged seizures and SE in DS.
Age-dependent dose calculations for common PET radionuclides and brain radiotracers in nonhuman primate computational models.
Medical physics, 2020

The combination of nonhuman primates (NHPs) with the state-of-the-art molecular imaging technologies allows for within-subject longitudinal research aiming at gaining new insights into human normal and disease conditions and provides an ideal foundation for future translational studies of new diagnostic tools, medical interventions, and therapies. However, radiation dose estimations for nonhuman primates from molecular imaging probes are lacking and are difficult to perform experimentally. The aim of this work is to construct age-dependent NHP computational model series to estimate the absorbed dose to NHP specimens in common molecular imaging procedures.
A broader phenotype of persistence emerges from individual differences in response to extinction.
Psychonomic bulletin & review, 2018

The typical practice of averaging group performance during extinction gives the impression that responding declines gradually and homogeneously. However, previous studies of extinction in human infants have shown that some individuals persist in responding, whereas others abruptly cease responding. As predicted by theories of control, the infants who quickly resign typically display signs of sadness and despair when the expected reward is omitted. Using genetically diverse mice, here we observed a similar pattern of individual differences and the associated phenotypes. After learning to approach a food reward, upon extinction, some animals rapidly abandoned approach to the goal box, whereas other animals persisted in entering and searching the goal box. Interestingly, the persistent mice were slower to "give up" when confined to an inescapable pool of water (a test asserted to be indicative of susceptibility to depression) and exhibited a more extensive pattern of search for omitted rewards. Thus, extinction reveals a continuum in persistence, in which low values might reflect a susceptibility to the negative effects of stress and might predispose individuals to depression.
Visual Outcomes in Leber Hereditary Optic Neuropathy Patients With the m.11778G>A (MTND4) Mitochondrial DNA Mutation.
Journal of neuro-ophthalmology : the official journal of the North American Neuro-Ophthalmology Society, 2020

Leber hereditary optic neuropathy (LHON) is a maternally inherited bilaterally blinding optic neuropathy, predominantly affecting otherwise healthy young individuals, mostly men. The visual prognosis is generally poor, with most patients worsening to at least 20/200 visual acuity. The m.11778G>A (MTND4) mitochondrial DNA mutation is the most common cause of LHON and is associated with poor outcomes and limited potential for meaningful visual recovery. Treatments for LHON are limited, and clinical trials are hampered by inadequate data regarding the natural history of visual loss and recovery. In this article, we review the current literature specifically related to visual function of LHON patients with the m.11778G>A mutation.
Spinal muscular atrophy due to double gene conversion event.
The International journal of neuroscience, 2011

Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by degeneration of the anterior horn cells of the spinal cord. The survival motor neuron (SMN) gene has been identified as an SMA-determining gene. SMN exists as two copies in 5q13, and deletions in exons 7 and 8 of the telomeric copy (SMN(T)) occur in 95% of patients, regardless of disease severity. In a minority of patients, exon 7 but not exon 8 of SMN(T) appears deleted. We now report a patient with typical features of SMA type II who carried homozygous deletions of SMN(T) exon 7 and centromeric SMN (SMN(C)) exon 8 but retained SMN(T) exon 8 and SMN(C) exon 7. Sequence analysis demonstrated that SMN(C) exon 7 was adjacent to SMN(T) exon 8 on both SMN copies, indicating a double conversion. We confirm that sequence conversion is a common event in SMA and is associated with the milder form of the disease. The severity, however, can be modified in either positive or negative direction by other factors.
Elastase as a potential biomarker for radiation-induced gut wall injury of the distal bowel in an experimental mouse model.
Acta oncologica (Stockholm, Sweden), 2018

Traditionally, elastase has been used to study exocrine activity of the pancreas in patients with chronic pancreatitis and cystic fibrosis, and calprotectin as a marker for gut-wall inflammation in patients with inflammatory bowel disease. The aim of the study was to find out whether elastase and calprotectin could be used as inflammatory markers for radiation-induced gut wall injury of the distal bowel.
ON BECOMING ABLE TO PLAY: INDIVIDUAL CHILD PSYCHOANALYTIC PSYCHODRAMA AND THE DEVELOPMENT OF SYMBOLIZATION.
The Psychoanalytic quarterly, 2017

In this paper, the authors analyze the relevance and transformative potential of individual psychoanalytic psychodrama in the treatment of children with severe impairments in symbolization. Central features of this modality, including promoting the representation of early traumatic experiences, are presented and discussed. Specific features include double-envelope containment of the co-therapists' group and play leader, consequent diffraction of the transference-determining portrayal, gradual integration, and initial figuration of coexisting split-off fragments. Drawing on in-depth clinical material, the authors show how psychodrama tempers the potentially traumatic effects of the encounter with the object, allowing these patients to access the transitional area of play.
Giving meaning to the social world in autism spectrum disorders: Olfaction as a missing piece of the puzzle?
Neuroscience and biobehavioral reviews, 2020

Altered social cognition is a core feature of Autism Spectrum Disorders (ASD). These impairments have been explained as the consequence of compromised social motivational mechanisms that limit social interest and activate a cascade of social deficits. Following this rational, we argue that approaches capable of surpassing ASD usual restraints (e.g., deficits in verbal abilities), and able to assign social meaning, could be more effective at responding to these difficulties. In this framework, we propose that olfaction, as well as cross-modal integration strategies involving both visual and olfactory domains, may have such potential. In fact, most of socioemotional processing deficits in ASD have been shown in an uni-modal perspective, mainly with visual stimuli. However, the social environment involves other modalities and is typically multisensorial. Given the potential of olfaction as a gateway for socioemotional information in ASD, we argue in favor of studying olfactory perception, as well as visuo-olfactory integration, given the potential of these approaches to drive effective interventions and give the access to a meaningful social world in ASD.
Identification of intrinsic primary afferent neurons in mouse jejunum.
Neurogastroenterology and motility, 2020

The gut is the only organ system with intrinsic neural reflexes. Intrinsic primary afferent neurons (IPANs) of the enteric nervous system initiate intrinsic reflexes, form gut-brain connections, and undergo considerable neuroplasticity to cause digestive diseases. They remain inaccessible to study in mice in the absence of a selective marker. Advillin is used as a marker for primary afferent neurons in dorsal root ganglia. The aim of this study was to test the hypothesis that advillin is expressed in IPANs of the mouse jejunum.
Opportunities and limitations of genetically modified nonhuman primate models for neuroscience research.
Proceedings of the National Academy of Sciences of the United States of America, 2020

The recently developed new genome-editing technologies, such as the CRISPR/Cas system, have opened the door for generating genetically modified nonhuman primate (NHP) models for basic neuroscience and brain disorders research. The complex circuit formation and experience-dependent refinement of the human brain are very difficult to model in vitro, and thus require use of in vivo whole-animal models. For many neurodevelopmental and psychiatric disorders, abnormal circuit formation and refinement might be at the center of their pathophysiology. Importantly, many of the critical circuits and regional cell populations implicated in higher human cognitive function and in many psychiatric disorders are not present in lower mammalian brains, while these analogous areas are replicated in NHP brains. Indeed, neuropsychiatric disorders represent a tremendous health and economic burden globally. The emerging field of genetically modified NHP models has the potential to transform our study of higher brain function and dramatically facilitate the development of effective treatment for human brain disorders. In this paper, we discuss the importance of developing such models, the infrastructure and training needed to maximize the impact of such models, and ethical standards required for using these models.
Cardosin A endocytosis mediated by integrin leads to lysosome leakage and apoptosis of epithelial cells.
Proteins, 2019

Cardosin A is an aspartic protease present in large amount in the pistils of cardoon flowers. This protease is known to contain an -Arg-Gly-Asp- (RGD) motif located on the molecular surface. In this study, we found that isolated recombinant cardosin A attached to human epithelial cells A549, mediated by the binding of its RGD motif to cell surface integrins. The cell bound cardosin A was internalized to endosomes and lysosomes and triggered the permeability of lysosomal membrane leading to apoptosis of the epithelial cells. These events are identical to those observed for three RGD-containing aspartic proteases, Saps 4-6, secreted by Candida albicans. Such a process, which has been called the Trojan Horse mechanism, is believed to benefit the invasion of C. albican into the epithelium of the host. The location of the RGD motifs of cardosin A and Saps 4-6 are on the opposite ends of the homologous three-dimensional structures, suggesting that the Trojan Horse mechanism is insensitive to the RGD position. Current finding also suggests that cardosin A may have a defensive function against the ingestion of cardoon flowers by human, insects, and other herbivores.
Effects of reward associations on components of attentional network.
Acta psychologica, 2021

Previous research has revealed the influence of reward associations on attentional selection and control. The attentional network can be divided into three components according to its function: Alerting, orienting, and executive control. In the current research, we used training-test procedure and attention network test variant to investigate the effects of color-based reward associations on alerting (Experiment 1), orienting (Experiment 2), executive control (Experiment 3), as well as the interactions among these three networks (Experiment 4). The findings were as follows: Compared with colors previously associated with low reward, colors previously associated with high reward trigger stronger alerting and orienting effects (Experiments 1 and 2), and they had stronger interference effects when functioning as features of flanker distractor (Experiment 3). More importantly, reward associations had only a positive impact on the interaction of orienting by executive control but not on the interaction of alerting by executive control (Experiment 4). In summary, reward associations have different effects on the three attentional networks and can enhance the interaction of orienting by executive control.
[Computational neuroanatomy and microstructure imaging using magnetic resonance imaging].
Der Nervenarzt, 2017

Current computational neuroanatomy focuses on morphological measurements of the brain using standard magnetic resonance imaging (MRI) techniques. In comparison quantitative MRI (qMRI) typically provides a better tissue contrast and also greatly improves the sensitivity and specificity with respect to the microstructural characteristics of tissue.
Human VGF-Derived Antidepressant Neuropeptide TLQP62 Promotes SH-SY5Y Neurite Outgrowth.
Journal of molecular neuroscience : MN, 2020

TLQP62 is a neuropeptide derived from the neurotrophin-inducible VGF (non-acronymic) protein with antidepressant-like properties capable of inducing increased memory on the mouse hippocampus by promoting neurogenesis and synaptic plasticity through brain-derived neurotropic factor (BDNF) and its receptor tyrosine receptor kinase B (TrkB). Human SH-SY5Y neuroblastoma-derived cell line is widely used in neuroscience research and is known to undergo neurodifferentiation in the presence of all-trans retinoic acid by upregulating the expression of TrkB, making cells responsive to BDNF. As TLQP62 promotes BDNF expression, which in turn activates a BDNF/TrkB/CREB (cAMP response element-binding protein) pathway that upregulates VGF expression, there is a VGF-BDNF regulatory loop that seems to regulate neurogenesis. Therefore, here, we evaluate by morphological observation the ability of human TLQP62 to induce neuritogenesis of human SH-SY5Y neuroblastoma-derived cell line in a retinoic acid and BDFN-like way, making this cell line a suitable cell model for further studies concerning TLQP62 molecular mechanisms and signalling pathways. SIGNIFICANCE STATEMENT: VGF has been widely explored for its role in emotional behaviour and neuropsychiatric illness (Bartolomucci et al. 2011). Although VGF levels were found reduced in leukocytes of depressed patients, after antidepressant treatment or voluntary exercise, those levels were found to be restored in the hippocampus (Hunsberger et al. 2007; Thakker-Varia et al. 2007). Administration to hippocampal cells of TLQP62 produced an increase in synaptic charge that could explain this antidepressants effects (Alder et al. 2003). This interesting role of TLQP62 in the brain, especially in the hippocampus, makes this neuropeptide an attractive target for further investigation of its role in neurogenesis, learning, memory, and neurological disorders, and possible treatment development. Thus, the identification of a receptor(s) for this peptide and associated signalling pathway(s) is of high importance, as well as a proper cell model to perform those studies.
An overview of the role of interleukin-8 in colorectal cancer.
Cytokine, 2020

Colorectal Cancer (CRC), a common malignancy, is developing globally among people. Mutagenic insults activate peripheral nucleated cells to secrete chemokines in order to cause an inflammatory state. Despite the presence of multi-retrieving factors, elevated production of minor cytokines may speed-up the sever stages of the baseline inflammation targeting normal compensatory mechanism. IL-8 is a pro-inflammatory cytokine that is believed to be up-regulated in CRC to proceed primary condition into tumor behavior via induction of proliferation, angiogenesis and metastasis. Here, we assess the role of IL-8 in every step of CRC from signaling pathway and formation to invasion and discuss around new perspective therapy that targets IL-8 to manage CRC worldwide incidence and survival rate, more precisely.
CD36 gene polymorphism rs1761667 (G > A) is associated with hypertension and coronary artery disease in an Iranian population.
BMC cardiovascular disorders, 2019

CD36 is associated with regulation of lipid metabolism, atherosclerosis, and blood pressure. Moreover, its variation may be involved in the development of hypertension and/or coronary artery disease (CAD). The present study was conducted to investigate the possible association of CD36 rs1761667 (G > A) polymorphism with hypertension and/or CAD in the southeastern of Iran.
Correlated Brain Indexes of Semantic Prediction and Prediction Error: Brain Localization and Category Specificity.
Cerebral cortex (New York, N.Y. : 1991), 2021

With strong and valid predictions, grasping a message is easy, whereas more demanding processing is required in the absence of robust expectations. We here demonstrate that brain correlates of the interplay between prediction and perception mechanisms in the understanding of meaningful sentences. Sentence fragments that strongly predict subsequent words induced anticipatory brain activity preceding the expected words; this potential was absent if context did not strongly predict subsequent words. Subjective reports of certainty about upcoming words and objective corpus-based measures correlated with the size of the anticipatory signal, thus establishing its status as a semantic prediction potential (SPP). Crucially, there was an inverse correlation between the SPP and the N400 brain response. The main cortical generators of SPP and N400 were found in inferior prefrontal cortex and posterior temporal cortex, respectively. Interestingly, sentence meaning was reflected by both measures, with additional category-specific sources of SPPs and N400s falling into parieto-temporo-occipital (visual) and frontocentral (sensorimotor) areas for animal- and tool-related words, respectively. These results show that the well-known brain index of semantic comprehension, N400, has an antecedent with different brain localization but similar semantic discriminatory function. We discuss whether N400 dynamics may causally depend on mechanisms underlying SPP size and sources.
Human Mpv17-like protein with a mitigating effect on mtDNA damage is involved in cAMP/PKA signaling in the mitochondrial matrix.
Biochimica et biophysica acta. Molecular cell research, 2020

Human Mpv17-like protein (M-LPH/Mpv17L) is thought to play a role in minimizing mitochondrial dysfunction caused by mitochondrial DNA (mtDNA) damage. We have recently demonstrated that, in addition to an increase of mtDNA damage, M-LPH-knockout (M-LPH-KO) in HepG2 cells causes a significant reduction of mitochondrial transcription factor A (TFAM) protein, an essential factor for mtDNA maintenance, along with an increase in its phosphorylation. These intracellular changes suggested an association of M-LPH with the cAMP/PKA signaling pathway, as selective degradation of TFAM by mitochondrial protease is driven by protein kinase A (PKA)-dependent phosphorylation. In the present study, we observed that M-LPH-KO in HepG2 cells caused an increase in the level of mitochondrial cAMP and a reduction of total cellular cyclic nucleotide phosphodiesterase (PDE) activity. In vitro-synthesized M-LPH showed PDE activity, which was inhibited by IBMX, a non-selective inhibitor of PDE. Furthermore, M-LPH-KO promoted PKA-dependent phosphorylation of some mitochondrial proteins. Taken together, the present findings suggest that M-LPH, which has structural features atypical of PDE family members, might be a novel human PDE involved in cAMP/PKA signaling in the mitochondrial matrix.
