High resolution behavioral and neural activity representation using a geometrical approach.
Scientific reports, 2020

Available tools for recording neuronal activity are limited and reductive due to massive data arising from high-frequency measurements. We have developed a method that utilizes variance within the physiological activity and includes all data points per measurement. Data is expressed geometrically in a physiologically meaningful manner, to represent a precise and detailed view of the recorded neural activity. The recorded raw data from any pair of electrodes was plotted and following a covariance calculation, an eigenvalues and chi-square distribution were used to define the ellipse which bounds 95% of the raw data. We validated our method by correlating specific behavioral observation and physiological activity with behavioral tasks that require similar body movement but potentially involve significantly different neuronal activity. Graphical representation of telemetrically recorded data generates a scatter plot with distinct elliptic geometrical properties that clearly and significantly correlated with behavior. Our reproducible approach improves on existing methods by allowing a dynamic, accurate and comprehensive correlate using an intuitive output. Long-term, it may serve as the basis for advanced machine learning applications and animal-based artificial intelligence models aimed at predicting or characterizing behavior.
Mutation-independent Proteomic Signatures of Pathological Progression in Murine Models of Duchenne Muscular Dystrophy.
Molecular & cellular proteomics : MCP, 2020

The absence of the dystrophin protein in Duchenne muscular dystrophy (DMD) results in myofiber fragility and a plethora of downstream secondary pathologies. Although a variety of experimental therapies are in development, achieving effective treatments for DMD remains exceptionally challenging, not least because the pathological consequences of dystrophin loss are incompletely understood. Here we have performed proteome profiling in tibialis anterior muscles from two murine DMD models (
Medical and neuropsychiatric phenomena depicted in two Spanish medieval texts of Marian miracles.
Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2018

In the history of Christianity, veneration of the Virgin Mary reached its greatest intensity in the XIII century. Her perceived impact on daily life was tremendous and not surprisingly this extended to the spheres of disease and healing. The purpose of this study is to compare the medical and neuropsychiatric findings in two XIII century Spanish texts of Marian miracles, both examples of the popular Catholicism (vs. official catholic doctrine). We analyzed the medical and neuropsychiatric events in the Cantigas de Santa Maria (Canticles of St. Mary, CSM), composed at the court of Alfonso X and the Milagros de Nuestra Señora (The Miracles of Our Lady, MNS), written by Gonzalo de Berceo. Among the 25 miracles reported in the MNS, medically relevant facts were addressed in 19 miracles with a total of 23 recorded events (including resurrection or escape from death in five) and demonic possession in three (one with witchcraft/deicide). The most common medical subjects were ergotism, obstetric-gynecological, sudden death, intellectual disability/illiteracy, encephalopathy/alcohol intoxication, suicide (with self-mutilation/castration), infanticide, infections, and absence of body decomposition after death. The 427 canticles in the CSM contain 270 medically relevant facts. Neuropsychiatric conditions were alluded to in 98 songs. Blindness and dystonia/weakness/deformities were the most common phenomena. Illuminations detailed many of the medical facts in the CSM, but not in the MNS. Medically relevant facts were described in both texts, but with more details in the CSM. Neurological conditions were more often described in the CSM, psychiatric conditions in the MNS.
Clinical aspects of a large group of adults with Angelman syndrome.
American journal of medical genetics. Part A, 2021

Descriptions of the clinical features of Angelman syndrome (AS) have mainly been focused on children. Here, we describe the evolution of the clinical phenotypes of AS in adulthood, using clinical data from 95 individuals (mean age 31.6 years, median 29.0 years, range 18-83 years), with genetically confirmed AS. Data was collected through physical examination and inspection of medical records, combined with questionnaires and interviews. Adults with AS experience substantial debilitating health problems. Constipation, reflux, visual problems, scoliosis, behavioral and sleeping problems occurred frequently and require appropriate attention. Epilepsy was reported in 57% of adults, negatively affecting the level of functioning. Non-convulsive status epilepticus was not observed in the adults, however some individuals developed prolonged episodes of rhythmic shaking while awake. A decline in mobility was noted in the majority of adults. A minority of adults with AS showed microcephaly. Taken together, this first phenotypic study of adults with AS to include in person interviews with care-givers and physical examination of patients, including the eldest adult reported to date, provides important insight in the development of the syndrome into adulthood. This knowledge is required to improve care for adult individuals with AS and to evaluate future therapies for this group.
rAAV-related therapy fully rescues myonuclear and myofilament function in X-linked myotubular myopathy.
Acta neuropathologica communications, 2020

X-linked myotubular myopathy (XLMTM) is a life-threatening skeletal muscle disease caused by mutations in the MTM1 gene. XLMTM fibres display a population of nuclei mispositioned in the centre. In the present study, we aimed to explore whether positioning and overall distribution of nuclei affects cellular organization and contractile function, thereby contributing to muscle weakness in this disease. We also assessed whether gene therapy alters nuclear arrangement and function. We used tissue from human patients and animal models, including XLMTM dogs that had received increasing doses of recombinant AAV8 vector restoring MTM1 expression (rAAV8-cMTM1). We then used single isolated muscle fibres to analyze nuclear organization and contractile function. In addition to the expected mislocalization of nuclei in the centre of muscle fibres, a novel form of nuclear mispositioning was observed: irregular spacing between those located at the fibre periphery, and an overall increased number of nuclei, leading to dramatically smaller and inconsistent myonuclear domains. Nuclear mislocalization was associated with decreases in global nuclear synthetic activity, contractile protein content and intrinsic myofilament force production. A contractile deficit originating at the myofilaments, rather than mechanical interference by centrally positioned nuclei, was supported by experiments in regenerated mouse muscle. Systemic administration of rAAV8-cMTM1 at doses higher than 2.5 × 10
Your guess is as good as mine: A registered report assessing physiological markers of fear and anxiety to the unknown in individuals with varying levels of intolerance of uncertainty.
International journal of psychophysiology : official journal of the International Organization of Psychophysiology, 2020

Individuals who score high in Intolerance of Uncertainty (IU) have a tendency to find uncertainty and the unknown aversive. However, there is a dearth of literature on the extent to which the known vs. the unknown during threatening contexts induce fear and anxiety in individuals with high IU. In the following registered report we attempted to address this question by manipulating the known and unknown in the threat of predictable and unpredictable aversive events task. Throughout the task, we measured a variety of self-report (ratings of valence and arousal) and physiological indices (skin conductance, pupil dilation, orbicularis oculi, corrugator supercilii). We collected data from 93 participants. Higher IU, relative to lower IU was associated with: (1) less discriminatory orbicularis oculi activity between cue and interstimulus interval periods across conditions, and (2) larger corrugator supercilii activity to the known predictable shock condition and smaller corrugator supercilii activity to the known unpredictable shock condition, compared to the other conditions. These findings provide evidence that IU-related biases manifest differently depending on the physiological marker of fear and anxiety and the type of known-unknown threat i.e. orbicularis oculi activity was related to generalisation across conditions, whilse corrugator supercilii activity reflected distress/relief during conditions with known threat. Ultimately, this research will inform future models of IU in relation to anxiety and stress disorders.

Angela J. Grippo: Award for Distinguished Scientific Early Career Contributions to Psychology.
The American psychologist, 2012

Presents a short biography of one of the winners of the American Psychological Association's Award for Distinguished Scientific Early Career Contributions to Psychology. The 2012 winner is Angela J. Grippo for her creative contributions in investigating the association between depression and cardiovascular disease in preclinical animal models. Using sophisticated behavioral and neuroscience methods, Grippo found changes in sympathetic tone, immune system activation, and serotonin levels, as well as increased susceptibility to life-threatening arrhythmias, in a rodent model of depression, changes similar to those observed in humans with depression and heart disease. Her research illustrates how animal models of physiology and behavior advance understanding of the connections among depression, stress, and physical disease in humans. Grippo's Award citation and a selected bibliography are also presented here.
Subjective visual vertical and visual dependency in patients with multiple sclerosis.
Multiple sclerosis and related disorders, 2020

Spatial orientation is an inherent ability governed by the complex integration of visual, vestibular and proprioceptive inputs. The degree to which an individual relies upon visual cues, as opposed to the vestibular or proprioceptive cues, is termed visual dependence. Although abnormal visual dependence has been documented in other neurological disorders, it is not known whether MS leads to visual dependence, and if so whether this is related to disease progression, clinical disability, or neuro-inflammatory burden in the central nervous system.
The Development of Cladribine Tablets for the Treatment of Multiple Sclerosis: A Comprehensive Review.
Drugs, 2020

Cladribine is a purine nucleoside analog initially developed in the 1970s as a treatment for various blood cancers. Due to the molecule's ability to preferentially reduce T and B lymphocytes, it has been developed into an oral formulation for the treatment of multiple sclerosis (MS). The unique proposed mechanism of action of cladribine allows for the therapy to be delivered orally over two treatment-week cycles per year, one cycle at the beginning of the first month and one cycle at the beginning of the second month of years 1 and 2, with the potential for no further cladribine treatment required in years 3 and 4. This review summarizes the clinical development program for cladribine tablets in patients with MS, including the efficacy endpoints and results from the 2-year phase III CLARITY study in patients with relapsing-remitting MS (RRMS), the 2-year CLARITY EXTENSION study, and the phase III ORACLE-MS study in patients with a first clinical demyelinating event at risk for developing MS. Efficacy results from the phase II ONWARD study, in which cladribine tablets were administered as an add-on to interferon-β therapy in patients with RRMS, are also summarized. A review of all safety data, including lymphopenia, infections, and malignancies, is provided based on data from all trials in patients with MS, including the initial parenteral formulation studies. Based on these data, cladribine tablets administered at 3.5 mg/kg over 2 years have been approved across the globe for various forms of relapsing MS.

The Journal of neuroscience : the official journal of the Society for Neuroscience, 2021

In this short review, I describe from personal experience how every step in the career of any scientist, no matter how disjointed and pragmatic each might seem at the time, will almost inevitably meld together, to help us all tackle novel projects. My postdoctoral research in Paul Greengard's laboratory, where I investigated neurotransmitter-mediated phosphorylation of Synapsin I, was instrumental in my career progression, and Paul's support was instrumental in my ability to make a leap into independent research.
Fingolimod increases oligodendrocytes markers expression in epidermal neural crest stem cells.
European journal of pharmacology, 2020

Epidermal neural crest stem cells (EPI-NCSCs) are propitious candidates for cell replacement therapy and supplying neurotrophic factors in the neurological disorders. Considering the potential remyelinating and regenerative effects of fingolimod, in this study, we evaluated its effects on EPI-NCSCs viability and the expression of neurotrophic and oligodendrocyte differentiation factors. EPI-NCSCs, extracted from the bulge of rat hair follicles, were characterized and treated with fingolimod (0, 50, 100, 200, 400, 600, 1000, and 5000 nM). The cell viability was evaluated by MTT assay at 6, 24 and 72 h. The expression of neurotrophic and differentiation factors in the cells treated with 100 and 400 nM fingolimod were measured at 24 and 120 h. Fingolimod at 50-600 nM increased the cells viability after 6 h, with no change at the higher concentrations. The highest concentration (5000nM) induced toxicity at 24 and 72 h. NGF and GDNF genes expression were decreased at 120 h, but on the contrary, brain derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3) were increased by both concentrations at both time points. Oligodendrocyte markers including platelet-derived growth factor receptor A (PDGFRα), neuron-glial antigen 2 (NG2) and growth associated protein 43 (GAP43) were elevated at 120 h, which was accompanied with reduce in stemness markers (Nestin and early growth response 1 (EGR1)). Fingolimod increased the expression of neurotrophic factors in EPI-NCSCs, and guided them to oligodendrocyte fate. Therefore, fingolimod in combination with EPI-NCSCs, can be considered as a promising approach for demyelinating neurological disorders.
Low-grade epilepsy-associated tumour management with or without presurgical evaluation: a multicentre, retrospective, observational study of postsurgical epilepsy outcome.
Epileptic disorders : international epilepsy journal with videotape, 2020

Low-grade epilepsy-associated neuroepithelial tumours (LEATs) encompass the broad spectrum of tumours associated with epilepsy. Since the postsurgical seizure outcome in LEATs is favourable, it is speculated that epileptological presurgical evaluation (EPE) might not be required for patients with LEATs. A multicentre study involving referring epilepsy and neurosurgery centres was performed, aimed at evaluating postsurgical epilepsy outcome in patients with LEATs, with and without EPE, including long-term video-EEG monitoring (vEEGM). In total, 149 surgically treated patients were enrolled (age: 31±14 years; age at surgery: 26.4±13.1 years; males; 55.7%) with histopathological confirmation of LEATs and follow-up of more than six months. All patients had undergone standard assessment: clinical, routine EEG and brain MRI. In addition to vEEGM, EPE included other additional investigations. Epileptologists did not assess patients treated in neurosurgical centres. The EPE was performed in 51% of patients. Histopathological diagnosis revealed ganglioglioma in 43.6%, DNET in 32.9%, pilocytic astrocytoma in 17.4%, and others in 6.1% of patients. The majority of patients were seizure-free (ILAE epilepsy surgery outcome Class 1; 71.1%). The median follow-up period was 36 months. Patients who were rendered seizure-free were younger (mean age: 24.2±12.2) than those who were not seizure-free (31.8±14.0) (p=0.001). No difference was identified between evaluated and non-evaluated patients with respect to seizure freedom (p=0.45). EPE patients had a longer epilepsy duration (median: 10 years) and a higher proportion of drug resistance (73.6%) compared to non-evaluated patients (median: two years; 26.4%) (p<0.001). Based on a significant difference in major clinical variables, that may well affect postoperative results, the similar postsurgical seizure outcome in groups with and without EPE observed in our study should be considered with caution, and conclusions as to whether there is value in formal presurgical evaluation in LEAT patients cannot be drawn. Our data strongly encourage the clear need for continued discussion around such patients at epilepsy management conferences.

Generation of Gene Knockout and Gene Replacement with Complete Removal of Full-length Endogenous Transcript Using CRISPR-Trap.
Bio-protocol, 2018

This protocol describes the application of the CRISPR-Trap from designing of the gene targeting strategy to validation of successfully edited clones that was validated on various human cell lines, among them human induced pluripotent stem cells (hiPSCs). The advantage of CRISPR-Trap over conventional approaches is the complete removal of any endogenous full-length transcript from the target gene. CRISPR-Trap is applicable for any target gene with no or little coding sequence in its first exon. Several human cell lines and different genes have so far been edited successfully with CRISPR-Trap.
Neurocognitive functioning after electroconvulsive therapy in late-life depression: A 4-year prospective study.
Acta psychiatrica Scandinavica, 2021

Despite the proven efficacy and safety of ECT, there is still concern about the possible cognitive side effects of ECT in older patients. In this study, we aimed to characterize the long-term cognitive effects of ECT in patients with late-life depression (LLD) from before the start until 4 years after the index ECT course.
Long-term Changes in the Central Amygdala Proteome in Rats with a History of Chronic Cocaine Self-administration.
Neuroscience, 2020

The central nucleus of the amygdala (CeA) is a striatum-like structure that contains mainly inhibitory circuits controlling a repertoire of (mal)adaptive behaviors related to pain, anxiety, motivation, and addiction. Neural activity in the CeA is also necessary for the expression of persistent and robust drug seeking, also termed 'incubation of drug craving.' However, neuroadaptations within this brain region supporting incubated drug craving have not been characterized. Here, we conducted a comprehensive analysis of protein expression in the CeA of male rats after prolonged (45-day) abstinence from extended-access cocaine self-administration using a quantitative proteomic approach. The proteomic analysis identified 228 unique proteins altered in cocaine rats relative to animals that received saline. Out of the identified proteins, 160 were downregulated, while 68 upregulated. Upregulation of tyrosine hydroxylase and downregulation of neural cell-adhesion protein contactin-1 were validated by immunoblotting. Follow-up analysis by the Ingenuity Pathway Analysis tool revealed alterations in protein networks associated with several neurobehavioral disorders, cellular function and morphology, as well as axogenesis, long-term potentiation, and receptor signaling pathways. This study suggests that chronic cocaine self-administration, followed by a prolonged abstinence results in reorganization of specific protein signaling networks within the CeA that may underlie incubated cocaine craving and identifies potential novel 'druggable' targets for the treatment of cocaine use disorder (CUD).
