[A case of encephalopathy showing various psychiatric and autonomic symptoms with positive anti-ganglionic acetylcholine receptor (gAChR) antibody].
Rinsho shinkeigaku = Clinical neurology, 2019

An 84-year-old woman developed spontaneous recurring mutism. During the periods in which she was able to speak, she described that she had a peculiar delusion where her body was melting away. She did not obey orders although she was able to move her limbs spontaneously. Severe fluctuations in blood pressure measurements were observed; they were unaffected by postural changes. She also had urinary retention and constipation. Her psychiatric and autonomic symptoms showed marked daily and diurnal fluctuations. The brain MRI showed no abnormality in the limbic system or temporal lobes. The cerebrospinal fluid showed slightly elevated protein with normal cells counts. This case was initially thought to be an encephalopathy of unknown etiology. On subsequent testings she was shown to have positive anti-ganglionic acetylcholine receptor (gAChR) antibodies. Although the initial steroid pulse and intravenous immunoglobulin therapies markedly improved both psychiatric and autonomic symptoms, they turned ineffective in subsequent recurrences. We were not able to treat her with plasmapheresis or with other immunisuppressive drugs because of her poor general status, thus their effectiveness could not be determined. Judging from her clinical course, in which immunotherapy was effective although somewhat limited, a possible involvement of an autoimmune mechanism was suspected; however, the exact pathogenesis remains undetermined. It is possible that in this case there may have been an involvement of the immune system and that the patient might have had an encephalopathy with anti-gAChR antibodies.
From lipid locus to drug target through human genomics.
Cardiovascular research, 2018

In the last decade, over 175 genetic loci have robustly been associated to levels of major circulating blood lipids. Most loci are specific to one or two lipids, whereas some (SUGP1, ZPR1, TRIB1, HERPUD1, and FADS1) are associated to all. While exposing the polygenic architecture of circulating lipids and the underpinnings of dyslipidaemia, these genome-wide association studies (GWAS) have provided further evidence of the critical role that lipids play in coronary heart disease (CHD) risk, as indicated by the 2.7-fold enrichment for macrophage gene expression in atherosclerotic plaques and the association of 25 loci (such as PCSK9, APOB, ABCG5-G8, KCNK5, LPL, HMGCR, NPC1L1, CETP, TRIB1, ABO, PMAIP1-MC4R, and LDLR) with CHD. These GWAS also confirmed known and commonly used therapeutic targets, including HMGCR (statins), PCSK9 (antibodies), and NPC1L1 (ezetimibe). As we head into the post-GWAS era, we offer suggestions for how to move forward beyond genetic risk loci, towards refining the biology behind the associations and identifying causal genes and therapeutic targets. Deep phenotyping through lipidomics and metabolomics will refine and increase the resolution to find causal and druggable targets, and studies aimed at demonstrating gene transcriptional and regulatory effects of lipid associated loci will further aid in identifying these targets. Thus, we argue the need for deeply phenotyped, large genetic association studies to reduce costs and failures and increase the efficiency of the drug discovery pipeline. We conjecture that in the next decade a paradigm shift will tip the balance towards a data-driven approach to therapeutic target development and the application of precision medicine where human genomics takes centre stage.
Environmental and ecological factors of stomach cancer incidence and mortality: a systematic review study on ecological studies.
Reviews on environmental health, 2020

Stomach cancer (SC) is one of the most common and deadly types of cancer. It is the third leading cause of cancer deaths worldwide. The effect of environmental and ecological factors in SC have been assessed in some studies. Thus, we aimed to synthesize the environmental and ecological factors of SC incidence and mortality.
A review of the recent advances in neuroimaging of frontotemporal lobar degeneration.
Journal of neurosurgical sciences, 2017

The term "frontotemporal lobar degeneration" (FTLD) includes a large set of neurodegenerative diseases, which are heterogeneous in their genetic, pathologic and clinical aspects. This review will focus on the most recent contribution of neuroimaging tools on the diagnosis, characterization and pathogenesis of FTLD.
The Location and Rate of the Phosphate Release Step in the Muscle Cross-Bridge Cycle.
Biophysical journal, 2020

It is controversial whether the phosphate (Pi) release step in the cross-bridge cycle occurs before or after the first tension-generating step and whether it is fast or slow. We have therefore modified our previous model of the frog cross-bridge cycle by including a Pi release step either before (model A) or after (model B) the first tension-generating step and refined the two models by downhill simplex runs against experimental data for the force-velocity relation and the tension transients after length steps. Pi release step was initially made slow (70 s
Neuronal Ablation of Alpha/Beta Interferon (IFN-α/β) Signaling Exacerbates Central Nervous System Viral Dissemination and Impairs IFN-γ Responsiveness in Microglia/Macrophages.
Journal of virology, 2020

Alpha/beta interferon (IFN-α/β) signaling through the IFN-α/β receptor (IFNAR) is essential to limit virus dissemination throughout the central nervous system (CNS) following many neurotropic virus infections. However, the distinct expression patterns of factors associated with the IFN-α/β pathway in different CNS resident cell populations implicate complex cooperative pathways in IFN-α/β induction and responsiveness. Here we show that mice devoid of IFNAR1 signaling in calcium/calmodulin-dependent protein kinase II alpha (CaMKIIα) expressing neurons (CaMKIIcre:IFNAR
Neurological exclusiveness or unified science inclusiveness: Comment on Schwartz et al. (2016).
The American psychologist, 2016

Schwartz, Lilienfeld, Meca, and Sauvigné (2016) argue effectively and productively that neuroscience is monistic (excludes other fields) in a way that affects negatively psychology department makeup, psychology grant support, and the way students are trained. They conclude, rather, that it is important to effect an inclusion of different fields of psychology. This paper broadens and strengthens their position. However, it also points out that a call for inclusiveness raises a central question. How is inclusiveness to be accomplished? Without stipulation to the contrary the call is for an eclecticism. As Schwartz et al. indicate, unified theory is now rejected because grand theory in the past has been monistic. However, science moves on; there are unified theories today that are inclusive. Thus, development of an area in psychology is needed that studies, evaluates, and advances works that unify inclusively, the present article being an example. (PsycINFO Database Record
Characterization of intravitreally delivered capsid mutant AAV2-Cre vector to induce tissue-specific mutations in murine retinal ganglion cells.
Experimental eye research, 2016

Targeted expression of Cre recombinase in murine retinal ganglion cells (RGCs) by viral vector is an effective strategy for creating tissue-specific gene knockouts for investigation of genetic contribution to RGC degeneration associated with optic neuropathies. Here we characterize dosage, efficacy and toxicity for sufficient intravitreal delivery of a capsid mutant Adeno-associated virus 2 (AAV2) vector encoding Cre recombinase. Wild type and Rosa26 (R26) LacZ mice were intravitreally injected with capsid mutant AAV2 viral vectors. Murine eyes were harvested at intervals ranging from 2 weeks to 15 weeks post-injection and were assayed for viral transduction, transgene expression and RGC survival. 10(9) vector genomes (vg) were sufficient for effective in vivo targeting of murine ganglion cell layer (GCL) retinal neurons. Transgene expression was observed as early as 2 weeks post-injection of viral vectors and persisted to 11 weeks. Early expression of Cre had no significant effect on RGC survival, while significant RGC loss was detected beginning 5 weeks post-injection. Early expression of viral Cre recombinase was robust, well-tolerated and predominantly found in GCL neurons suggesting this strategy can be effective in short-term RGC-specific mutation studies in experimental glaucoma models such as optic nerve crush and transection experiments. RGC degeneration with Cre expression for more than 4 weeks suggests that Cre toxicity is a limiting factor for targeted mutation strategies in RGCs.
A phase 2a randomised, double-blind, placebo-controlled, parallel-group, add-on clinical trial of ebselen (SPI-1005) as a novel treatment for mania or hypomania.
Psychopharmacology, 2020

Lithium is an effective prophylactic and anti-manic treatment in bipolar disorder; however, its use is declining through perceived poor tolerance and toxicity. Lithium inhibits inositol monophosphatase (IMPase), a probable key therapeutic mechanism. The anti-inflammatory drug, ebselen, also inhibits IMPase and appears well-tolerated and safe.
Reduced sensory and motor nerve conduction velocities in moderate drinkers.
Addiction biology, 2000

The mechanism responsible for peripheral nerve dysfunction in chronic alcoholism has not been fully elucidated either in terms of its relationship to the quantity of alcohol consumed or to nutritional status. As part of a series of studies to address these issues, the effects of moderate drinking (60-90 g ethanol per day) or heavy drinking (> 100 g ethanol per day) on peripheral nervous function and thiamine status was measured in 73 patients admitted to a detoxification unit. Electromyographic evaluation revealed significant reductions in median and ulnar sensory and motor nerve conduction velocities in both moderate drinkers (n = 30) and heavy drinkers (n = 43) compared to age-matched controls. Twelve moderate drinkers and 25 heavy drinkers manifested clinical neurological signs of peripheral neuropathy. Thiamine deficiency, as revealed by erythrocyte transketolase activation assay, was detected in two moderate drinkers and seven heavy drinkers but was not significantly correlated with electromyographic alterations with the exception of ulnar nerves. These findings provide evidence for significant early peripheral nerve dysfunction in moderate drinkers and a possible contributory role of thiamine deficiency to the ulnar nerve conduction deficits. Whether deficits in other water-soluble vitamins or a direct neurotoxic effect of ethanol are implicated in alcoholic peripheral neuropathy awaits further studies.
Neuronal Activity Regulates Blood-Brain Barrier Efflux Transport through Endothelial Circadian Genes.
Neuron, 2020

The blood vessels in the central nervous system (CNS) have a series of unique properties, termed the blood-brain barrier (BBB), which stringently regulate the entry of molecules into the brain, thus maintaining proper brain homeostasis. We sought to understand whether neuronal activity could regulate BBB properties. Using both chemogenetics and a volitional behavior paradigm, we identified a core set of brain endothelial genes whose expression is regulated by neuronal activity. In particular, neuronal activity regulates BBB efflux transporter expression and function, which is critical for excluding many small lipophilic molecules from the brain parenchyma. Furthermore, we found that neuronal activity regulates the expression of circadian clock genes within brain endothelial cells, which in turn mediate the activity-dependent control of BBB efflux transport. These results have important clinical implications for CNS drug delivery and clearance of CNS waste products, including Aβ, and for understanding how neuronal activity can modulate diurnal processes.
Nuclear Respiratory Factor 1 (NRF1) Transcriptional Activity-Driven Gene Signature Association with Severity of Astrocytoma and Poor Prognosis of Glioblastoma.
Molecular neurobiology, 2020

Despite tremendous progress in understanding the pathobiology of astrocytoma, major gaps remain in our knowledge of the molecular basis underlying the aggressiveness of high-grade astrocytoma (glioblastoma - GBM). Recently, we and others have shown nuclear respiratory factor 1 (NRF1) transcription factor being highly active in human cancers, but its role in astrocytoma remains unknown. Therefore, the purpose of this study was to uncover the role of NRF1 in the progression of GBM. NRF1 has higher mRNA expression and transcription factor activity in astrocytoma compared to non-tumor brain tissue. NRF1 activity also correlated with the aggressiveness of cancer. Increased NRF1 TF activity coupled with overexpression of RHOG was associated with poor survival of GBM patients. NRF1 activity was associated with transcriptomic signatures of neurogenesis, cell stemness, epithelial-mesenchymal transition and cell cycle progression. Overexpression of CDK4, AKT1, APAF1, HDAC1, NBN, TGFB1, & TNFRSF1A and downregulation of CASP3, IL7, STXBP1 and OPA1 predicted GBM malignancy in high expressors of NRF1 activity. Increased expression of the NRF1 motif containing genes, H6PD, NAT10, NBEAL2, and RNF19B predicted poor survival of IDH1 wild-type GBM patients. Poor survival outcomes and resistance to Temozolomide therapy were associated with higher NRF1 expression including its targets - LDHA, ZMAT3, NSUN2, ARMC5, NDEL1, CLPTM1L, ALKBH5, YIPF5, PPP2CA, and TFG. These findings suggest that aberrant NRF1 activity may contribute to the pathogenesis of GBM and severity of astrocytoma. Further analyses of NRF1 gene signatures will pave the way for next generation targeted therapies and drug combination strategies for GBM patients.
The Fat Mass and Obesity-Associated Protein (FTO) Regulates Locomotor Responses to Novelty via D2R Medium Spiny Neurons.
Cell reports, 2019

Variations in the human FTO gene have been linked to obesity and altered connectivity of the dopaminergic neurocircuitry. Here, we report that fat mass and obesity-associated protein (FTO) in dopamine D2 receptor-expressing medium spiny neurons (D2 MSNs) of mice regulate the excitability of these cells and control their striatopallidal globus pallidus external (GPe) projections. Lack of FTO in D2 MSNs translates into increased locomotor activity to novelty, associated with altered timing behavior, without impairing the ability to control actions or affecting reward-driven and conditioned behavior. Pharmacological manipulations of dopamine D1 receptor (D1R)- or D2R-dependent pathways in these animals reveal altered responses to D1- and D2-MSN-mediated control of motor output. These findings reveal a critical role for FTO to control D2 MSN excitability, their projections to the GPe, and behavioral responses to novelty.
Parkinsonism in children: Clinical classification and etiological spectrum.
Parkinsonism & related disorders, 2021

Infantile- and childhood-onset parkinsonism is mainly due to genetic alterations and is an exceedingly rare condition, unlike Parkinson's disease (PD), which is one of the most common neurologic disorders in adulthood. The clinical characterization of parkinsonism during early stages of neuromotor development is controversial due to the lack of consensus regarding the clinical criteria of PD or parkinsonism in the immature brain. The classification here proposed is based on a review of conditions that emerge during infancy and childhood, with key symptoms evocative of adult parkinsonism. The proposed nosography is based on age at presentation, clinical features, outcome, and etiological background. It includes developmental parkinsonism, infantile degenerative parkinsonism, parkinsonism in the setting of neurodevelopmental disorders, parkinsonism in the setting of multisystem brain diseases, juvenile parkinsonism and dystonia-parkinsonism, and acquired parkinsonism. The subgroups denoting peculiar clinical presentations as a consequence of disease impact on the immature brain are developmental parkinsonism due to monoamine metabolic disorders and infantile degenerative parkinsonism caused by DAT and WASR2 defects. More tardive parkinsonisms occur in genetic conditions that cause a generalized derangement of neurodevelopmental processes, such as those due to MECP2, NR4A2, SCN1A, and RAB39B. Some conditions presenting with neurodevelopmental disorder can progress later, disclosing their neurodegenerative nature (i.e. WDR45 and KCND3). Finally, new emerging conditions with childhood-onset parkinsonism arise from the cumulative effect of multiple genetic lesions.
Genetic and environmental contributions to diagnostic fluctuation in anorexia nervosa and bulimia nervosa.
Psychological medicine, 2021

Anorexia nervosa and bulimia nervosa are two severe eating disorders associated with high premature mortality, suicidal risk and serious medical complications. Transition between anorexia nervosa and bulimia nervosa over the illness course and familial co-aggregation of the two eating disorders imply aetiological overlap. However, genetic and environmental liabilities to the overlap are poorly understood. Quantitative genetic research using clinical diagnosis is needed.
Elevated caudate connectivity in cognitively normal Parkinson's disease patients.
Scientific reports, 2020

Mild cognitive impairment (MCI) is common in Parkinson's disease patients. However, its underlying mechanism is not well understood, which has hindered new treatment discoveries specific to MCI. The aim of this study was to investigate functional connectivity changes of the caudate nucleus in cognitively impaired Parkinson's patients. We recruited 18 Parkinson's disease patients-10 PDNC [normal cognition Parkinson's disease; Montreal Cognitive Assessment (MoCA) ≥ 26], 8 PDLC (low cognition Parkinson's disease; MoCA < 26) -and 10 age-matched healthy controls. All subjects were scanned with resting-state functional magnetic resonance imaging (MRI) and perfusion MRI. We analyzed these data for graph theory metrics and Alzheimer's disease-like pattern score, respectively. A strong positive correlation was found between the functional connectivity of the right caudate nucleus and MoCA scores in Parkinson's patient groups, but not in healthy control subjects. Interestingly, PDNC's functional connectivity of the right caudate was significantly higher than both PDLC and healthy controls, while PDLC and healthy controls were not significantly different from each other. We found that Alzheimer's disease-like metabolic/perfusion pattern score correlated with MoCA scores in healthy controls, but not in Parkinson's disease. Increased caudate connectivity may be related to a compensatory mechanism found in cognitively normal patients with Parkinson's disease. Our findings support and complement the dual syndrome hypothesis.
Progress report on new antiepileptic drugs: A summary of the Fifteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XV). I. Drugs in preclinical and early clinical development.
Epilepsia, 2020

Since 1992, the Eilat Conferences have provided a forum for all stakeholders in the epilepsy community to appraise the latest data on new antiepileptic drugs and emergency seizure treatments, including, in recent years, updates on progress with the development of novel monitoring and therapeutic devices. Because of the COVID-19 pandemic, the Fifteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XV) was held as a fully virtual conference on July 27-30, 2020 for the sessions on drugs and on August 3, 2020 for the sessions on devices, and was attended during the 5 days by >500 participants from 63 countries. This progress report summarizes key preclinical and initial (phase 1) clinical data on eight investigational treatments that are currently in early development, including 2-deoxy-D-glucose, GAO-3-02, JNJ-40411813, NBI-921352, NTX-001, sec-butylpropylacetamide, XEN1101, and XEN496. This report provides an overview of current scenarios in the area of treatment discovery and development. The information presented illustrates a variety of innovative strategies, including exploration of compounds with novel mechanisms of action, transplantation of interneurons into epileptogenic brain regions, and the targeting of rare, previously neglected syndromes.
Transfer effects of step training on stepping performance in untrained directions in older adults: A randomized controlled trial.
Gait & posture, 2017

Although step training improves the ability of quick stepping, some home-based step training systems train limited stepping directions and may cause harm by reducing stepping performance in untrained directions. This study examines the possible transfer effects of step training on stepping performance in untrained directions in older people.
Transfer of the peroneal component of the sciatic nerve in total brachial plexus lesion: An anatomical feasibility study.
Injury, 2020

Closed brachial plexus lesions (BPLs) are generally associated with a traumatic mechanism of forced traction between the neck and the shoulder-arm complex. For brachial plexus reconstruction different techniques have been proposed with donor motor nerves like intercostal nerves, or the ipsilateral cervical plexus, the phrenic nerve, the contralateral C7 root, and many others. Despite all these surgical possibilities, the overall recovery is generally poor and not satisfactory. The principal drawback is linked to the loss of upper limb proprioception, in a way that dramatically influences even a good motor recovery, so in complete BPLs the sensory loss still represents a debilitating problem. In this anatomical feasibility study, the possibility to transfer the peroneal component of the sciatic nerve as a donor for complete BPLs has been evaluated. This technique would conceptually bring an important motor and sensory contribution to the upper limb using pure motor and sensory branches of the sciatic nerve. Performing immediate tendon transfer for foot drop palsy could significantly decrease the morbidity of the surgical procedure.
Diagnosis and management of intralabyrinthine schwannoma: case series and review of the literature.
Acta bio-medica : Atenei Parmensis, 2020

Intralabyrinthine schwannoma (ILS) is a rare benign tumor affecting cochlear and vestibular nerves, whose symptoms are generally unspecific and frequently responsible for a late diagnosis. Radiological examinations, with particular reference to magnetic resonance imaging (MRI), represent the only diagnostic technique to identify ILS. On computed tomography ILS can only be indirectly suspected by the presence of surrounding bone remodeling, whereas MRI provides direct visualization of the neoplasm as a filling defect within the labyrinth with vivid contrast enhancement. At the same time, MRI is also helpful in defining ILS anatomical extension into adjacent structures and in planning therapeutic management. Here we report three representative cases of ILS with new pictorial imaging features to improve ILS early detection and optimize subsequent therapeutic management.
An uncommon case of nonconvulsive status epilepticus successfully treated with enteral Brivaracetam.
Acta bio-medica : Atenei Parmensis, 2021

We present a case of a woman affected by nonconvulsive status epilepticus (NCSE) caused by cerebral hyperperfusion syndrome (CHS) after carotid endarterectomy (CEA) who was successfully treated with Brivaracetam (BRV) administered via nasogastric tube (NGT).
Role of prenatal magnetic resonance imaging in fetuses with isolated agenesis of corpus callosum in the era of fetal neurosonography: A systematic review and meta-analysis.
Acta obstetricia et gynecologica Scandinavica, 2021

Corpus callosum agenesis (ACC) is frequently diagnosed during fetal life; its prognosis depends also on additional anomalies. The additional value of fetal magnetic resonance imaging (MRI) in fetuses with "isolated" complete (cACC) and partial (pACC) agenesis of the corpus callosum on ultrasound is still debated.
