The brain as a complex network: assessment of EEG-based functional connectivity patterns in patients with childhood absence epilepsy.
Epileptic disorders : international epilepsy journal with videotape, 2020

The human brain is increasingly seen as a dynamic neural system, the function of which relies on a diverse set of connections between brain regions. To assess these complex dynamical interactions, formalism of complex networks was suggested as one of the most promising tools to offer new insight into the brain's structural and functional organization, with a potential also for clinical implications. Irrespective of the brain mapping technique, modern network approaches have revealed fundamental aspects of normal brain-network organization, such as small-world and scale-free patterns, hierarchical modularity, and the presence of hubs. Moreover, the utility of these approaches, to gain a better understanding of neurological diseases, is of great interest. In the present contribution, we first describe the basic network measures and how the brain networks are constructed on the basis of brain activity data in order to introduce clinical neurologists to this new theoretical paradigm. We then demonstrate how network formalism can be used to detect changes in EEG-based functional connectivity patterns in six paediatric patients with childhood absence epilepsy. Notably, our results do not only indicate enhanced synchronicity during epileptic episodes but also reveal specific spatial changes in the electrical activity of the brain. We argue that the network-based evaluation of functional brain networks can provide clinicians with more detailed insight into the activity of a pathological brain and can also be regarded as a support for objective diagnosis and treatment for various neurological diseases.

The aim was to perform a systematic review of current evidences on clinical presentation of COVID-19, focusing on upper airway symptoms in order to help otolaryngologists identifying suspected cases.
SP8 and SP9 coordinately promote D2-type medium spiny neuron production by activating 
Development (Cambridge, England), 2018

Dopamine receptor DRD1-expressing medium spiny neurons (D1 MSNs) and dopamine receptor DRD2-expressing medium spiny neurons (D2 MSNs) are the principal projection neurons in the striatum, which is divided into dorsal striatum (caudate nucleus and putamen) and ventral striatum (nucleus accumbens and olfactory tubercle). Progenitors of these neurons arise in the lateral ganglionic eminence (LGE). Using conditional deletion, we show that mice lacking the transcription factor genes
Mid-adolescent stress differentially affects binge-like intake of sucrose across estrous cycles in female rats
Physiology & behavior, 2021

Binge eating disorder (BED), characterized by excessive food consumption within a discrete period of time, is the most prevalent of all eating disorders, with higher rates in women than men. Chronic stress, particularly during adolescence, is a significant risk factor for BED in women, but the mechanism underlying this relationship remains elusive. We investigated the phenomenon by testing the impact of mid-adolescent intermittent physical stress (IPS) on binge-like intake of sucrose in adult female rats, assessing how the behavior changed across reproductive cycles. One hundred and nineteen Long-Evans rats were exposed to IPS (n = 59) or no stress (NS; n = 60) for 12 days during mid-adolescence (PD35-46). Binge-like eating was induced in adult animals using an intermittent access protocol: animals were provided with 12 h or 24 h access to sucrose, 12 h access to saccharin, or 12 h access to food over 28 days. After 1- or 28-day abstinence, compulsive responding for sucrose was measured using a conditioned suppression paradigm. Rats given 12 h access to sucrose developed binge-like intake, measured as increased consumption during the first hour; the effect was magnified in IPS animals and most pronounced during proestrous. Solution intake in IPS rats was predicted by open arm entries in the elevated plus maze, suggesting that increased risk-taking behavior is associated with greater binge-like eating. IPS blocked conditioned suppression after 28 days of abstinence, pointing to a role of mid-adolescent stress in compulsivity. Collectively, these findings emphasize the impact of stress on the emergence of binge eating in females and suggest that intervention programs for women with a history of adolescent adversity should be investigated as a means to reduce risk for BED.
Neurobehavioral Grand Rounds introduction: Does near drowning in ice water prevent anoxic induced brain injury?
Journal of the International Neuropsychological Society : JINS, 2008

Cold water near-drowning is often thought to be neuroprotective in individuals with anoxia of a longer duration than that usually required to produce irreversible neurologic damage. There is a paucity of data in adults with cold water near-drowning that assess neuropsychological outcomes. Information regarding long-term effects of near cold water near-drowning on neuropathology, neuropsychological and neurobehavioral outcomes are uncommon. This paper provides an introduction to two cases of cold water near-drowning reported in this issue of JINS by Sameulson and colleagues and provides background information for interpretation of the findings of these cases in the context of outcomes following anoxia.
Quality of care indicators for a resuscitation unit: A descriptive study and proposal.
Medicine, 2018

There are lack of indicators of quality of care in resuscitation units of emergency departments. With the aim of proposing a series of indicators to evaluate the quality of care delivered in hospital resuscitation areas, we conducted a descriptive study of 7579 admissions to the resuscitation unit of an emergency department at a Spanish hospital between 2012 and 2016. The proposed indicators were the percentage of patients attending to the emergency department admitted to the resuscitation area by level of triage, the length of stay, the percentage of patients moved to intensive care and surgery at disposition, the mortality in the area or in the emergency department within 24 hours of disposition, and the data completeness. A majority of the patients (62.6%) were men and the median age was 68 years. Over 99% of the required data were recorded. Median length of stay in the resuscitation unit was 0.87 hours (interquartile range, 0.5-1.5). Approximately 80% of patients categorized as an emergency on admission to the emergency department were admitted to the resuscitation unit, although the proportion of urgency patients was higher. The main disposition destination was a trauma cubicle (82.3% of cases). Mortality was 0.41%.Specific indicators are needed to assess the quality of care delivery in resuscitation units. We believe that our findings will provide new insights into the work done to date in this field.
Understanding Cognitive Deficit After Subarachnoid Hemorrhage: A Memory Focused Approach.
Cureus, 2020

Aneurysmal subarachnoid hemorrhage (aSAH) is a prevalent condition affecting a large portion of the population, many of them still in productive ages. Memory impairment is a common factor amongst those patients. Memory exerts a pivotal role in productivity. That is why it is important to understand how it can be affected in post-aSAH patients. There are certain areas most affected in cases of memory disturbances, as well as its functional connections with crucial cerebral regions. Active research on functional magnetic resonance and diffusion tension imaging is used to identify compromised areas within the brain. There are suggested factors regarding poor performance, such as cerebrospinal fluid drainage and new infarction areas, which should be addressed properly to benefit these patients and simultaneously help them return to a productive and functional life.
Evidence that Maackia amurensis seed lectin (MASL) exerts pleiotropic actions on oral squamous cells to inhibit SARS-CoV-2 infection and COVID-19 disease progression.
Research square, 2020

COVID-19 was declared an international public health emergency in January, and a pandemic in March of 2020. There are over 23 million confirmed COVID-19 cases that have cause over 800 thousand deaths worldwide as of August 19th, 2020. COVID-19 is caused by the SARS-CoV-2 virus. SARS-CoV-2 presents a surface "spike" protein that binds to the ACE2 receptor to infect host cells. In addition to the respiratory tract, SARS-Cov-2 can also infect cells of the oral mucosa, which also express the ACE2 receptor. The spike and ACE2 proteins are highly glycosylated with sialic acid modifications that direct viral-host interactions and infection. Maackia amurensis seed lectin (MASL) has a strong affinity for sialic acid modified proteins and can be used as an antiviral agent. Here, we report that MASL targets the ACE2 receptor, decreases ACE2 expression and glycosylation, suppresses binding of the SARS-CoV-2 spike protein, and decreases expression of inflammatory mediators by oral epithelial cells that cause ARDS in COVID-19 patients. This work identifies MASL as an agent with potential to inhibit SARS-CoV-2 infection and COVID-19 related inflammatory syndromes.
Prenatal alcohol exposure reduces posterior dorsomedial striatum excitability and motivation in a sex- and age-dependent fashion.
Neuropharmacology, 2020

Prenatal alcohol exposure (PAE)-induced clinical symptoms have been widely reported but effective treatments are not yet available due to our limited knowledge of the neuronal mechanisms underlying behavioral outputs. Operant behaviors, including both goal-directed and habitual actions, are essential for everyday life. The dorsomedial striatum (DMS) and the dorsolateral striatum (DLS) have been identified as mediating each type of instrumental behavior, respectively. The current studies were designed to evaluate the effects of PAE (i.e., 3 g/kg, twice a day on gestational days 17-20) on goal-directed vs. habitual behaviors in both females and males during their adolescent and adult stages. We found that PAE-treated adult, but not adolescent, males display similar habitual oral sucrose self-administration but reduced goal-directed sucrose self-administration, compared to those treated by prenatal control (water) exposure (PCE). There were no differences in either habitual or goal-directed sucrose taking between PCE- vs. PAE-treated adolescent and adult females. These results indicate sex- and age-specific effects of PAE on operant behaviors. Further, whole-cell patch clamp recordings showed that the excitability of medium-sized spiny neurons (MSNs) in the posterior DMS (pDMS), but not the anterior DMS (aDMS), was significantly decreased in PAE-treated adult male rats. Notably, chemogenetic enhancement of MSN excitability in the pDMS by the DREADD agonist, compound 21, rescued the motivation of PAE-treated male adult rats. These data suggest that the pDMS may be a key neuronal substrate mediating the PAE-induced low motivation in male adults.
Understanding complex dynamics of behavioral, neurochemical and transcriptomic changes induced by prolonged chronic unpredictable stress in zebrafish.
Scientific reports, 2020

Stress-related neuropsychiatric disorders are widespread, debilitating and often treatment-resistant illnesses that represent an urgent unmet biomedical problem. Animal models of these disorders are widely used to study stress pathogenesis. A more recent and historically less utilized model organism, the zebrafish (Danio rerio), is a valuable tool in stress neuroscience research. Utilizing the 5-week chronic unpredictable stress (CUS) model, here we examined brain transcriptomic profiles and complex dynamic behavioral stress responses, as well as neurochemical alterations in adult zebrafish and their correction by chronic antidepressant, fluoxetine, treatment. Overall, CUS induced complex neurochemical and behavioral alterations in zebrafish, including stable anxiety-like behaviors and serotonin metabolism deficits. Chronic fluoxetine (0.1 mg/L for 11 days) rescued most of the observed behavioral and neurochemical responses. Finally, whole-genome brain transcriptomic analyses revealed altered expression of various CNS genes (partially rescued by chronic fluoxetine), including inflammation-, ubiquitin- and arrestin-related genes. Collectively, this supports zebrafish as a valuable translational tool to study stress-related pathogenesis, whose anxiety and serotonergic deficits parallel rodent and clinical studies, and genomic analyses implicate neuroinflammation, structural neuronal remodeling and arrestin/ubiquitin pathways in both stress pathogenesis and its potential therapy.
The relationship between depression and metabolic control parameters in type 2 diabetic patients: A cross-sectional and feasibility interventional study.
International journal of clinical practice, 2021

Substantial evidence supports a bidirectional relationship between diabetes and clinical depression. However, little is known about the effect of treating one condition on the control of the other. Thus, this study aimed to determine the prevalence of depression among Type II diabetes mellitus (T2DM) patients and to assess the efficacy and feasibility of escitalopram treatment of depression on their metabolic control parameters.
Quantitative MRI-Based Analysis Identifies Developmental Limbic Abnormalities in PCDH19 Encephalopathy.
Cerebral cortex (New York, N.Y. : 1991), 2020

Protocadherin-19 (PCDH19) is a calcium dependent cell-adhesion molecule involved in neuronal circuit formation with prevalent expression in the limbic structures. PCDH19-gene mutations cause a developmental encephalopathy with prominent infantile onset focal seizures, variably associated with intellectual disability and autistic features. Diagnostic neuroimaging is usually unrevealing. We used quantitative MRI to investigate the cortex and white matter in a group of 20 PCDH19-mutated patients. By a statistical comparison between quantitative features in PCDH19 brains and in a group of age and sex matched controls, we found that patients exhibited bilateral reductions of local gyrification index (lGI) in limbic cortical areas, including the parahippocampal and entorhinal cortex and the fusiform and lingual gyri, and altered diffusivity features in the underlying white matter. In patients with an earlier onset of seizures, worse psychiatric manifestations and cognitive impairment, reductions of lGI and diffusivity abnormalities in the limbic areas were more pronounced. Developmental abnormalities involving the limbic structures likely represent a measurable anatomic counterpart of the reduced contribution of the PCDH19 protein to local cortical folding and white matter organization and are functionally reflected in the phenotypic features involving cognitive and communicative skills as well as local epileptogenesis.
Diffuse Leptomeningeal Glioneuronal Tumor of Childhood.
AJNR. American journal of neuroradiology, 2020

Diffuse leptomeningeal glioneuronal tumor is a newly defined entity under the neuronal and mixed neuronal-glial tumors category in the 2016 World Health Organization classification of brain tumors. In this series, we report clinical, radiologic, and histologic findings in 7 cases of diffuse leptomeningeal glioneuronal tumor. Our cases and literature review indicate that the most characteristic imaging finding is diffuse intracranial and intraspinal nodular leptomeningeal thickening and enhancement. This is often associated with small cyst-like, nonenhancing lesions. It should be noted that tumors sometimes bear nontypical features, for example, presenting as a solitary spinal cord mass without leptomeningeal involvement or with a dominant intracranial mass. In children with characteristic imaging findings and without clinical features of infection, the radiologist has an opportunity to promptly raise the possibility of diffuse leptomeningeal glioneuronal tumor, and thereby, affect streamlined diagnostic evaluation.

Introduction: Endovascular Neurosurgery.
Neurosurgical focus, 2019

Remarkable developments in the field of endovascular neurosurgery have been witnessed in the last decade. The success of endovascular therapy for ischemic stroke treatment is now irrefutable, making it an accepted standard of care. Endovascular treatment of cerebral aneurysms is no longer limited to primary coiling but now includes options such as stent or balloon assistance and flow diversion and applications utilizing neck reconstruction, intrasaccular, and bifurcation-specific devices. Balloons, liquid embolic agents, and flow-directed catheters have revolutionized the treatment of arteriovenous malformations and fistulae. The ongoing development of endovascular tools has led to novel and expanding approaches (for example, transvenous arteriovenous malformation embolization and transradial access). With improved technology, transposterior communicating artery access and other endovascular strategies are being applied successfully across the anterior and posterior circulations and to lesions once deemed only surgically approachable. Yet, we would be remiss to attribute the successes of endovascular strategies only to the development of their tools. Improvements in both noninvasive and angiographic imaging (such as three-dimensional road map guidance) have provided a greater understanding of pathologic entities and allowed the pursuit of endovascular cures.In this issue of Neurosurgical Focus, we present a wide range of endovascular strategies for a variety of neurovascular pathologies. We hope this video supplement will not only demonstrate the applicability of tried-and-true endovascular strategies to difficult clinical situations but also highlight new and developing endovascular technologies. We thank the authors for their outstanding contributions.
Targeting macrophages by an aza-anthrapyrazole to ameliorate experimental autoimmune encephalomyelitis.
Multiple sclerosis and related disorders, 2020

Multiple sclerosis (MS) is an immune-mediated neurodegenerative disease in the central nerve system, in which both innate and adaptive immune cells are involved. BBR3378, an aza-anthrapyrazole prevents experimental autoimmune encephalomyelitis (EAE), an inflammatory condition similar to MS, by antagonizing T cell autoimmune responses. Here, we report BBR3378's regulatory effect on macrophages.
Do intrinsic brain functional networks predict working memory from childhood to adulthood?
Human brain mapping, 2020

Working memory (WM) is defined as the ability to maintain a representation online to guide goal-directed behavior. Its capacity in early childhood predicts academic achievements in late childhood and its deficits are found in various neurodevelopmental disorders. We employed resting-state fMRI (rs-fMRI) of 468 participants aged from 4 to 55 years and connectome-based predictive modeling (CPM) to explore the potential predictive power of intrinsic functional networks to WM in preschoolers, early and late school-age children, adolescents, and adults. We defined intrinsic functional networks among brain regions identified by activation likelihood estimation (ALE) meta-analysis on existing WM functional studies (ALE-based intrinsic functional networks) and intrinsic functional networks generated based on the whole brain (whole-brain intrinsic functional networks). We employed the CPM on these networks to predict WM in each age group. The CPM using the ALE-based and whole-brain intrinsic functional networks predicted WM of individual adults, while the prediction power of the ALE-based intrinsic functional networks was superior to that of the whole-brain intrinsic functional networks. Nevertheless, the CPM using the whole-brain but not the ALE-based intrinsic functional networks predicted WM in adolescents. And, the CPM using neither the ALE-based nor whole-brain networks predicted WM in any of the children groups. Our findings showed the trend of the prediction power of the intrinsic functional networks to cognition in individuals from early childhood to adulthood.
Identifying Plasma Biomarkers with high specificity for major depressive disorder: A multi-level proteomics study.
Journal of affective disorders, 2020

There are currently no objective diagnostic biomarkers for major depressive disorder (MDD) due to the biological complexity of the disorder. The existence of blood-based biomarkers with high specificity would be convenient for the clinical diagnosis of MDD.
Idiopathic Intracranial Hypertension - Characteristic MRI Features.
Headache, 2020

We present the case of 24-year-old woman who presented with chronic headaches with features of raised intracranial pressure and bilateral papilledema. Brain magnetic resonance imaging revealed the characteristic features of idiopathic intracranial hypertension. A diagnosis supported by clinical features and other ancillary tests. These features are important for physicians to recognize early, so that timely treatment may prevent permanent complications from this rare but potentially sight-threatening headache.
Advance computer analysis of magnetic resonance imaging (MRI) for early brain tumor detection.
The International journal of neuroscience, 2021

The brain tumor grows inside the skull and interposes with regular brain functioning. The tumor growth may possibly result in cancer at a later stage. The early detection of brain tumor is crucial for successful treatment of fatal disease. The tumor presence is normally detected by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) images. The MRI/CT images are highly complex and involve huge data. This requires highly tedious and time-consuming process for detection of small tumors for the neurologists. Thus, there is a need to develop an effective and less time-consuming imaging technique for early detection of brain tumors.
