Organ Fibrosis and Autoimmunity: The Role of Inflammation in TGFβ-Dependent EMT.
Biomolecules, 2021

Recent advances in our understanding of the molecular pathways that control the link of inflammation with organ fibrosis and autoimmune diseases point to the epithelial to mesenchymal transition (EMT) as the common association in the progression of these diseases characterized by an intense inflammatory response. EMT, a process in which epithelial cells are gradually transformed to mesenchymal cells, is a major contributor to the pathogenesis of fibrosis. Importantly, the chronic inflammatory microenvironment has emerged as a decisive factor in the induction of pathological EMT. Transforming growth factor-β (TGF-β), a multifunctional cytokine, plays a crucial role in the induction of fibrosis, often associated with chronic phases of inflammatory diseases, contributing to marked fibrotic changes that severely impair normal tissue architecture and function. The understanding of molecular mechanisms underlying EMT-dependent fibrosis has both a basic and a translational relevance, since it may be useful to design therapies aimed at counteracting organ deterioration and failure. To this end, we reviewed the recent literature to better elucidate the molecular response to inflammatory/fibrogenic signals in autoimmune diseases in order to further the specific regulation of EMT-dependent fibrosis in more targeted therapies.
The development of metacognitive ability in adolescence.
Consciousness and cognition, 2013

Introspection, or metacognition, is the capacity to reflect on our own thoughts and behaviours. Here, we investigated how one specific metacognitive ability (the relationship between task performance and confidence) develops in adolescence, a period of life associated with the emergence of self-concept and enhanced self-awareness. We employed a task that dissociates objective performance on a visual task from metacognitive ability in a group of 56 participants aged between 11 and 41 years. Metacognitive ability improved significantly with age during adolescence, was highest in late adolescence and plateaued going into adulthood. Our results suggest that awareness of one's own perceptual decisions shows a prolonged developmental trajectory during adolescence.
Improved smell pleasantness after odor-taste associative learning in humans.
Neuroscience letters, 2008

Whereas some aspects of olfactory hedonism in humans are present from birth, others form during development and throughout adulthood. Although it is generally agreed that such hedonic representations emerge by associative learning, it is not yet clear which learning parameters are prominent. The present study investigated the influence of number of trials on odor preference acquisition in human adults. Forty-eight subjects randomly assigned to three groups were tested in three sessions. In the first session, subjects ranked eight food odors from most pleasant to most unpleasant. The second session consisted in an associative learning, the two most neutral odors were randomly associated with a drink: one odor with water (CS-) and the other odor with a pleasant sweet solution (CS+). In the third session subjects ranked the eight food odors again. In group A, CS+ was paired three times with the US, and in group B only once; in group C, CS+ was paired only once with the US but with a total duration identical to that in group A. Results showed that CS+ was ranked as significantly more pleasant after learning in group A (p<.05), but not in groups B and C (p>.05). In conclusion, the study showed that a neutral smell can acquire positive emotional features after being paired with a pleasant taste, and that this learning depends on the number of associations between smell and taste.
Muscle Yap Is a Regulator of Neuromuscular Junction Formation and Regeneration.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 2017

Yes-associated protein (Yap) is a major effector of the Hippo pathway that regulates cell proliferation and differentiation during development and restricts tissue growth in adult animals. However, its role in synapse formation remains poorly understood. In this study, we characterized Yap's role in the formation of the neuromuscular junction (NMJ). In

Non-invasive brain stimulation (NIBS) techniques have emerged as a promising tool for understanding and treating psychiatric disorders, necessitating a caution in terms of interpreting research results.
Endovascular management of iatrogenic dissection into the petrous segment of the internal carotid artery during mechanical thrombectomy for acute stroke.
Journal of clinical neuroscience : official journal of the Neurosurgical Society of Australasia, 2020

Iatrogenic dissection of the internal carotid artery is a well-known complication that can occur during mechanical thrombectomy for acute stroke. The vast majority of these injuries are limited to the cervical segment, and only in exceptional circumstances do they require surgical intervention. In the present case, extension of the lesion into the petrous segment of the carotid artery resulted in an acute neurologic decline necessitating emergent endovascular repair. We discuss the nuances of managing an exceptionally rare presentation of this complication.
Metabolic Dysregulation of the Lysophospholipid/Autotaxin Axis in the Chromosome 9p21 Gene SNP rs10757274.
Circulation. Genomic and precision medicine, 2020

Common chromosome 9p21 single nucleotide polymorphisms (SNPs) increase coronary heart disease risk, independent of traditional lipid risk factors. However, lipids comprise large numbers of structurally related molecules not measured in traditional risk measurements, and many have inflammatory bioactivities. Here, we applied lipidomic and genomic approaches to 3 model systems to characterize lipid metabolic changes in common Chr9p21 SNPs, which confer ≈30% elevated coronary heart disease risk associated with altered expression of ANRIL, a long ncRNA.
Classical conditioning drives learned reward prediction signals in climbing fibers across the lateral cerebellum.
eLife, 2019

Classical models of cerebellar learning posit that climbing fibers operate according to a supervised learning rule to instruct changes in motor output by signaling the occurrence of movement errors. However, cerebellar output is also associated with non-motor behaviors, and recently with modulating reward association pathways in the VTA. To test how the cerebellum processes reward related signals in the same type of classical conditioning behavior typically studied to evaluate reward processing in the VTA and striatum, we have used calcium imaging to visualize instructional signals carried by climbing fibers across the lateral cerebellum in mice before and after learning. We find distinct climbing fiber responses in three lateral cerebellar regions that can each signal reward prediction. These instructional signals are well suited to guide cerebellar learning based on reward expectation and enable a cerebellar contribution to reward driven behaviors, suggesting a broad role for the lateral cerebellum in reward-based learning.
Complex regional pain syndrome after transradial cerebral intervention.
BMJ case reports, 2019

Access site complications from transradial approaches for endovascular interventions are uncommon and many are preventable. Complications described in the literature include hematoma, radial artery occlusion, vasospasm, and even compartment syndrome. Mild post-procedure discomfort reported by patients is typically self-limited and managed symptomatically with oral analgesics. Pain that has no obvious structural correlate and is unresponsive to intravenous narcotics is very unusual. We describe the diagnosis and management of a case of complex regional pain syndrome of the upper extremity after transradial stent-assisted coil embolization of a cerebral aneurysm.
Thyroid hormone autoantibodies: are they a better marker to detect early thyroid damage in patients with hematologic cancers receiving tyrosine kinase inhibitor or immunoregulatory drug treatments?
Current oncology (Toronto, Ont.), 2016

Unlike cytotoxic agents, novel antineoplastic drugs can variably affect thyroid function and so impair patient outcomes. However, the widely used standard thyroid tests have demonstrated low sensitivity for detecting early thyroid damage that leads to dysfunction of the gland. To find a more reliable thyroid marker, we assessed the presence of antibodies binding thyroid hormones (thAbs) in a cancer population undergoing potentially thyrotoxic treatment.
Relationship between prefrontal gray matter volumes and working memory performance in schizophrenia: a family study.
Schizophrenia research, 2014

Diffuse structural abnormalities in the prefrontal cortex have been reported in both schizophrenia patients and their nonpsychotic biological relatives. Additionally, working memory difficulties have long been documented in schizophrenia patients and have been associated with the genetic liability for the disorder. The present analysis investigated the relationship between prefrontal regional gray matter volumes and two facets of working memory in schizophrenia using a family study. Structural neuroimaging scans provided measurements of rostral middle, superior, and inferior prefrontal cortical gray matter volumes. Participants also completed a spatial working memory task that measured both short-term maintenance and manipulation of material in memory. Both schizophrenia patients and relatives had reduced superior and inferior frontal gray matter volumes. Schizophrenia patients demonstrated a spatial working memory deficit compared to both controls and relatives, with no greater impairment when required to manipulate material. Smaller prefrontal volumes in schizophrenia patients were associated with worse working memory performance. These relationships were absent in the nonpsychotic relatives and controls. Despite normative behavioral performance, nonpsychotic relatives demonstrated abnormalities in brain structure similar to those found in schizophrenia patients. Manipulation abilities were not more impaired than maintenance in schizophrenia patients. Consistent with other neuroimaging research, our results suggest that direct measures of the underlying biology may be more sensitive to the effects of the genetic liability for schizophrenia than behavioral measures.
Recurrent computations for visual pattern completion.
Proceedings of the National Academy of Sciences of the United States of America, 2018

Making inferences from partial information constitutes a critical aspect of cognition. During visual perception, pattern completion enables recognition of poorly visible or occluded objects. We combined psychophysics, physiology, and computational models to test the hypothesis that pattern completion is implemented by recurrent computations and present three pieces of evidence that are consistent with this hypothesis. First, subjects robustly recognized objects even when they were rendered <15% visible, but recognition was largely impaired when processing was interrupted by backward masking. Second, invasive physiological responses along the human ventral cortex exhibited visually selective responses to partially visible objects that were delayed compared with whole objects, suggesting the need for additional computations. These physiological delays were correlated with the effects of backward masking. Third, state-of-the-art feed-forward computational architectures were not robust to partial visibility. However, recognition performance was recovered when the model was augmented with attractor-based recurrent connectivity. The recurrent model was able to predict which images of heavily occluded objects were easier or harder for humans to recognize, could capture the effect of introducing a backward mask on recognition behavior, and was consistent with the physiological delays along the human ventral visual stream. These results provide a strong argument of plausibility for the role of recurrent computations in making visual inferences from partial information.
Do socioeconomic factors affect the prevalence of multiple sclerosis in Iran?
Acta neurologica Scandinavica, 2019

A rising trend for incidence of multiple sclerosis (MS) has been observed during the recent years in Iran. Several factors have been investigated as the reason, but socioeconomic determinants have been neglected. The present study aimed to investigate the relationship between Human Development Index (HDI), income and education and MS prevalence in the provinces of Iran.
Comparison of dopamine D1 and D5 receptor knockout mice for cocaine locomotor sensitization.
Psychopharmacology, 2008

There is compelling support for the contribution of dopamine and the D1R-like (D1R, D5R) receptor subfamily to the behavioral and neural effects of psychostimulant drugs of abuse. The relative roles of D1R and D5R subtypes in mediating these effects are not clear.
Redundancy and multifunctionality among spinal locomotor networks.
Journal of neurophysiology, 2020

c-Fos is used to identify system-wide neural activation with cellular resolution in vivo. However, c-Fos can only capture neural activation of one event. Targeted recombination in active populations (TRAP) allows the capture of two different c-Fos activation patterns in the same animal. So far, TRAP has only been used to examine brain circuits. This study uses TRAP to investigate spinal circuit activation during resting and stepping, giving novel insights of network activation during these events. The level of colabeled (c-Fos+ and TRAP+) neurons observed after performing two bouts of stepping suggests that there is a probabilistic-like phenomenon that can recruit many combinations of neural populations (synapses) when repetitively generating many step cycles. Between two 30-min bouts of stepping, each consisting of thousands of steps, only ∼20% of the neurons activated from the first bout of stepping were also activated by the second bout. We also show colabeling of interneurons that have been active during stepping and resting. The use of the FosTRAP methodology in the spinal cord provides a new tool to compare the engagement of different populations of spinal interneurons in vivo under different motor tasks or under different conditions.
The Concept of Contexts in Pain: Generalization of Contextual Pain-Related Fear Within a de Novo Category of Unique Contexts.
The journal of pain, 2018

The experience of unpredictable pain fluctuations can trigger anticipatory pain-related fear. When discrete predictors for pain are lacking, fear typically accrues to the broader environmental context: a phenomenon referred to as contextual pain-related fear. We examined whether conceptual similarity between discrete contexts facilitates pain-related fear generalization; this mechanism is known as category-level fear generalization. Using a voluntary joystick movement paradigm, pain-free participants performed movements in 2 contexts (within-subjects design); context was manipulated by varying background color screens. In the predictable context, one movement predicted pain and another did not. In the unpredictable context, 2 other movements never predicted pain but pain was unpredictably delivered during the context. Participants subsequently learned to categorize novel background colors (ie, generalization contexts) as being similar to either the unpredictable or predictable pain context. Then we tested fear generalization to these novel contexts. We measured self-reported pain-related fear, expectancy, and eyeblink startle. Results indicated higher pain-related fear reports, but no elevated startle responses, for generalization contexts that were trained to be similar to the original unpredictable context rather than the predictable pain context. This highlights a potential pathway through which neutral contexts can elicit pain-related fear and motivate avoidance behavior associated with chronic pain disability.
COgnitive behavioural therapy versus standardised medical care for adults with Dissociative non-Epileptic Seizures (CODES): statistical and economic analysis plan for a randomised controlled trial.
Trials, 2017

Dissociative seizures (DSs), also called psychogenic non-epileptic seizures, are a distressing and disabling problem for many patients in neurological settings with high and often unnecessary economic costs. The COgnitive behavioural therapy versus standardised medical care for adults with Dissociative non-Epileptic Seizures (CODES) trial is an evaluation of a specifically tailored psychological intervention with the aims of reducing seizure frequency and severity and improving psychological well-being in adults with DS. The aim of this paper is to report in detail the quantitative and economic analysis plan for the CODES trial, as agreed by the trial steering committee.
Origin of the low-level EMG during the silent period following transcranial magnetic stimulation.
Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology, 2012

The cortical silent period refers to a period of near silence in the electromyogram (EMG) after transcranial magnetic stimulation (TMS) of the motor cortex during contraction. However, low-level EMG of unknown origin is often present. We hypothesised that it arises through spinal reflexes. Sudden lengthening of the muscle as force drops during the silent period could excite muscle spindles and facilitate motoneurones.
A behavioral analysis of the impact of voluntary physical activity on hippocampus-dependent contextual conditioning.
Hippocampus, 2009

Voluntary physical activity induces molecular changes in the hippocampus consistent with improved hippocampal function, but few studies have explored the effects of wheel running on specific hippocampal-dependent learning and memory processes. The current studies investigated the impact of voluntary wheel running on learning and memory for context and extinction using contextual fear conditioning which is known to be dependent on the hippocampus. When conditioning occurred prior to the start of 6 weeks of wheel running, wheel running had no effect on memory for context or extinction (assessed with freezing). In contrast, when wheel running occurred for 6 weeks prior to conditioning, physical activity improved contextual memory during a retention test 24 h later, but did not affect extinction learning or memory. Wheel running had no effect on freezing immediately after foot shock presentation during conditioning, suggesting that physical activity does not affect the acquisition of the context-shock association or alter the expression of freezing, per se. Instead, it is argued that physical activity improves the consolidation of contextual memories in the hippocampus. Consistent with improved hippocampus-dependent context learning and memory, 6 weeks of wheel running also improved context discrimination and reduced the context pre-exposure time required to form a strong contextual memory. The effect of wheel running on brain-derived neurotrophic factor (BDNF) messenger ribonucleic acid (mRNA) in hippocampal and amygdala subregions was also investigated. Wheel running increased BDNF mRNA in the dentate gyrus, CA1, and the basolateral amygdala. Results are consistent with improved hippocampal function following physical activity.
MRI of endolymphatic hydrops in patients with Meniere's disease: a case-controlled study with a simplified classification based on saccular morphology.
European radiology, 2017

Endolymphatic hydrops (EH) can be studied in patients by MRI. With the semi-quantitative grading system, previous imaging studies showed discrepancies in the occurrence and grading of EH in patients with Meniere's disease (MD). Here, we compared the inversion of the saccule to utricle area ratio (SURI) with the semi-quantitative method of grading conventionally used to diagnose MD.
An automated system for intracellular and intranuclear injection.
Journal of neuroscience methods, 2008

The Xenopus oocyte expression system has played an important role in the study of cellular proteins, particularly in the field of membrane physiology; expression of transporters and ion channels has significantly advanced our knowledge of these membrane proteins and the rapid and easy expression of mutants has been crucial in many structure-function studies. Xenopus oocytes are an expression system in many ligand-binding assays and in functional screening for ion channel modulators. Several commercially available automated technologies use this system, generating a demand for large numbers of oocytes injected with ion channel genes. Injection of oocytes with genetic material is generally carried out manually. Here we describe an automated system capable of injecting up to 600 oocytes per hour. Oocytes are contained in microplates with conical wells, a simple calibration procedure by the operator is required and pipette filling and oocyte injection are carried out automatically. Following intracellular injection of mRNA coding for ligand-gated ion channels close to 100% of oocytes tested positive for expression, and intranuclear injection of cDNA gave a rate of expression >50%. Moreover, we demonstrate that this method can also be successfully applied to inject zebrafish embryos and could be extended to other cell types.
