Of Molecules and Mechanisms.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 2020

Without question, molecular biology drives modern neuroscience. The past 50 years has been nothing short of revolutionary as key findings have moved the field from correlation toward causation. Most obvious are the discoveries and strategies that have been used to build tools for visualizing circuits, measuring activity, and regulating behavior. Less flashy, but arguably as important are the myriad investigations uncovering the actions of single molecules, macromolecular structures, and integrated machines that serve as the basis for constructing cellular and signaling pathways identified in wide-scale gene or RNA studies and for feeding data into informational networks used in systems biology. This review follows the pathways that were opened in neuroscience by major discoveries and set the stage for the next 50 years.
Neuroimmunology Research. A Report from the Cuban Network of Neuroimmunology.
Behavioral sciences (Basel, Switzerland), 2018

Neuroimmunology can be traced back to the XIX century through the descriptions of some of the disease&rsquo;s models (e.g., multiple sclerosis and Guillain Barret syndrome, amongst others). The diagnostic tools are based in the cerebrospinal fluid (CSF) analysis developed by Quincke or in the development of neuroimmunotherapy with the earlier expression in Pasteur&rsquo;s vaccine for rabies. Nevertheless, this field, which began to become delineated as an independent research area in the 1940s, has evolved as an innovative and integrative field at the shared edges of neurosciences, immunology, and related clinical and research areas, which are currently becoming a major concern for neuroscience and indeed for all of the scientific community linked to it. The workshop focused on several topics: (1) the molecular mechanisms of immunoregulation in health and neurological diseases, (like multiple sclerosis, autism, ataxias, epilepsy, Alzheimer and Parkinson&rsquo;s disease); (2) the use of animal models for neurodegenerative diseases (ataxia, fronto-temporal dementia/amyotrophic lateral sclerosis, ataxia-telangiectasia); (3) the results of new interventional technologies in neurology, with a special interest in the implementation of surgical techniques and the management of drug-resistant temporal lobe epilepsy; (4) the use of non-invasive brain stimulation in neurodevelopmental disorders; as well as (5) the efficacy of neuroprotective molecules in neurodegenerative diseases. This paper summarizes the highlights of the symposium.
Practical approach for safe anesthesia in a COVID-19 patient scheduled for emergency laparotomy.
Journal of anaesthesiology, clinical pharmacology, 2020

COVID-19 patients presenting for emergency laparotomy require evaluation of surgical illness and viral disease. As these patients are likely to have a wide spectrum of deranged physiology and organ dysfunction, optimization should start preoperatively and continue through intraoperative and postoperative recovery periods along with appropriate antimicrobial cover. The goal should be not to delay damage control surgery in favor of evaluation and optimization. When a COVID-19 positive or suspected patient is to be operated for laparotomy, the situation often demands general anesthesia with invasive monitoring and analgesia complemented by regional anesthesia to minimize postoperative opioid requirements to facilitate early recovery. This particular article addresses the issues related to emergency laparotomy management in relation to COVID-19 patient. Healthcare workers should diligently use effective PPE and practice disinfection to prevent spread. Video-communication is an effective means of evaluation. Information expected from investigations should be weighed against risk of exposure to healthcare workers/laypersons. Simulation and memory aids should be used to familiarize team members with roles and techniques of management while in PPE. Step-wise detailed planning for patient transfer, anesthesia induction, maintenance and emergence, aid in enhancing HCW safety without compromising patient care.
Juvenile dermatomyositis presenting as complete heart block in a 10-year-old girl.
Paediatrics and international child health, 2020

Juvenile dermatomyositis (JDM) is an auto-immune inflammatory condition associated with cardiac disorders including conduction abnormalities and myocardial dysfunction. The time of presentation of cardiac abnormalities can range from disease onset to after long-term follow-up, emphasising the importance of screening for cardiac involvement in JDM. A previously healthy 10-year-old girl presented with syncope, fatigue and weakness associated with a heliotrope rash. JDM was diagnosed based on the clinical, laboratory and imaging findings. An ECG demonstrated complete heart block (CHB). All symptoms resolved following treatment with parenteral corticosteroids. In JDM, it is important to investigate for cardiac manifestations and in CHB to consider administering corticosteroids.
Neurogenesis After Stroke: A Therapeutic Perspective.
Translational stroke research, 2021

Stroke is a major cause of death and disability worldwide. Yet therapeutic strategies available to treat stroke are very limited. There is an urgent need to develop novel therapeutics that can effectively facilitate functional recovery. The injury that results from stroke is known to induce neurogenesis in penumbra of the infarct region. There is considerable interest in harnessing this response for therapeutic purposes. This review summarizes what is currently known about stroke-induced neurogenesis and the factors that have been identified to regulate it. Additionally, some key studies in this field have been highlighted and their implications on future of stroke therapy have been discussed. There is a complex interplay between neuroinflammation and neurogenesis that dictates stroke outcome and possibly recovery. This highlights the need for a better understanding of the neuroinflammatory process and how it affects neurogenesis, as well as the need to identify new mechanisms and potential modulators. Neuroinflammatory processes and their impact on post-stroke repair have therefore also been discussed.
Targeted deletions of complement lectin pathway genes improve outcome in traumatic brain injury, with MASP-2 playing a major role.
Acta neuropathologica communications, 2020

The lectin pathway (LP) of complement activation is believed to contribute to brain inflammation. The study aims to identify the key components of the LP contributing to TBI outcome as possible novel pharmacological targets. We compared the long-term neurological deficits and neuropathology of wild-type mice (WT) to that of mice carrying gene deletions of key LP components after experimental TBI. WT or MASP-2 (Masp2
Effect of single nucleotide polymorphism in thrombin-activatable fibrinolysis inhibitor on the risk of diabetic macrovascular disease.
Blood coagulation & fibrinolysis : an international journal in haemostasis and thrombosis, 2015

Hypofibrinolysis is commonly found in patients with diabetes mellitus and is associated with the increased risk for many diabetic complications. An important inhibitor of fibrinolysis, thrombin-activatable fibrinolysis inhibitor (TAFI), participates in hypofibrinolysis in diabetes mellitus and may be involved in diabetic macrovascular disease. The present study was designed to determine whether TAFI polymorphisms (505G/A and 1040C/T) and TAFI levels are correlated with the development of type 2 diabetes mellitus (T2DM) and macrovascular diseases (MVDs). A total of 249 clinical samples were collected, including 102 healthy individuals (H group), 44 T2DM patients without MVD (T group) and 103 T2DM patients with MVD (M group). The 505G/A polymorphism was equally represented in the three groups. In contrast, analysis of the 1040C/T polymorphism revealed a statistically lower percentage of the T allele in the M group than in the H group (P = 0.014). This difference was due to decreased T/T homozygotes in the M groups compared with the H group (P = 0.029). The antigen TAFI level was 31.72 ± 13.64% in the H group, 62.56 ± 18.77% in the T group (P < 0.05, compared with the H group) and 63.70 ± 15.76% in the M group (P < 0.05, compared with the H group). As high plasma TAFI level is associated with the increasing risk of T2DM, it may thus serve as a potential marker for the diagnosis of T2DM.
Brains and brawn: Stress-induced myokine abates nervous system aging.
Cell metabolism, 2021

Skeletal muscle secretes numerous systemic factors, termed myokines, which can regulate homeostasis of distal tissues. In this issue, Rai et al. (2021) identify and characterize a novel myokine, Amyrel, which is secreted under muscle proteasome stress and protects central nervous system health and function by enhancing protein quality control during aging.
Inhibition of striatal-enriched protein tyrosine phosphatase (STEP) activity reverses behavioral deficits in a rodent model of autism.
Behavioural brain research, 2020

Autism spectrum disorders (ASDs) are highly prevalent childhood illnesses characterized by impairments in communication, social behavior, and repetitive behaviors. Studies have found aberrant synaptic plasticity and neuronal connectivity during the early stages of brain development and have suggested that these contribute to an increased risk for ASD. STEP is a protein tyrosine phosphatase that regulates synaptic plasticity and is implicated in several cognitive disorders. Here we test the hypothesis that STEP may contribute to some of the aberrant behaviors present in the VPA-induced mouse model of ASD. In utero VPA exposure of pregnant dams results in autistic-like behavior in the pups, which is associated with a significant increase in the STEP expression in the prefrontal cortex. The elevated STEP protein levels are correlated with increased dephosphorylation of STEP substrates GluN2B, Pyk2 and ERK, suggesting upregulated STEP activity. Moreover, pharmacological inhibition of STEP rescues the sociability, repetitive and abnormal anxiety phenotypes commonly associated with ASD. These data suggest that STEP may play a role in the VPA model of ASD and STEP inhibition may have a potential therapeutic benefit in this model.
Perception of service users and their caregivers on primary care-based mental health services: a qualitative study in Nepal.
BMC family practice, 2020

Integration of mental health services into primary health care systems has been advocated as a strategy to minimize the tremendous mental health treatment gap, particularly in low- and middle-income countries. Barriers to integration of mental health into primary health care have been widely documented; however, very little is known about the perception of service users and their caregivers on primary care-based mental health services. This study assessed service users' and caregivers' perceptions of mental health services provided by trained primary health care workers in Nepal.
Clinical staging in amyotrophic lateral sclerosis: analysis of Edaravone Study 19.
Journal of neurology, neurosurgery, and psychiatry, 2021

Semantic language deficit developing following herpes simplex encephalitis: reorganization "cannibalising" language centers?
Neurocase, 2018

Herpes simplex virus encephalitis (HSVE) commonly presents with severe amnesia due to virus-mediated destruction of key regions in the temporal lobes, although language and executive impairment has been described. Little is known however of the long-term cognitive changes in these patients, including changes that may happen with cortical reorganization. We describe a patient with HSVE who presented with a highly unusual late-onset language syndrome, which may reflect distal cortical changes after her original injury.

Taking Rapid and Intermittent Cocaine Infusions Enhances Both Incentive Motivation for the Drug and Cocaine-induced Gene Regulation in Corticostriatal Regions.
Neuroscience, 2020

A goal in addiction research is to distinguish forms of neuroplasticity that are involved in the transition to addiction from those involved in mere drug taking. Animal models of drug self-administration are essential in this context. Here, we compared in male rats two cocaine self-administration procedures that differ in the extent to which they evoke addiction-like behaviours. We measured both incentive motivation for cocaine using progressive ratio procedures, and cocaine-induced c-fos mRNA expression, a marker of neuronal activity. Rats self-administered intravenous cocaine (0.25 mg/kg/infusion) for seven daily 6-hour sessions. One group had intermittent access (IntA; 6 minutes ON, 26 min OFF × 12) to rapid infusions (delivered over 5 s). This models the temporal kinetics of human cocaine use and produces robust addiction-like behaviour. The other group had Long access (LgA) to slower infusions (90 s). This produces high levels of intake without promoting robust addiction-like behaviour. LgA-90 s rats took twice as much cocaine as IntA-5 s rats did, but IntA-5 s rats showed greater incentive motivation for the drug. Following a final self-administration session, we quantified c-fos mRNA expression in corticostriatal regions. Compared to LgA-90 s rats, IntA-5 s rats had more cocaine-induced c-fos mRNA in the orbitofrontal and prelimbic cortices and the caudate-putamen. Thus, a cocaine self-administration procedure (intermittent intake of rapid infusions) that promotes increased incentive motivation for the drug also enhances cocaine-induced gene regulation in corticostriatal regions. This suggests that increased drug-induced recruitment of these regions could contribute to the neural and behavioural plasticity underlying the transition to addiction.
Hyporesponsivity to mu-opioid receptor agonism in the Wistar-Kyoto rat model of altered nociceptive responding associated with negative affective state.
Pain, 2021

Chronic pain is often comorbid with anxiety and depression, altering the level of perceived pain, which negatively affects therapeutic outcomes. The role of the endogenous mu-opioid receptor (MOP) system in pain-negative affect interactions and the influence of genetic background thereon are poorly understood. The inbred Wistar-Kyoto (WKY) rat, which mimics aspects of anxiety and depression, displays increased sensitivity (hyperalgesia) to noxious stimuli, compared with Sprague-Dawley (SD) rats. Here, we report that WKY rats are hyporesponsive to the antinociceptive effects of systemically administered MOP agonist morphine in the hot plate and formalin tests, compared with SD counterparts. Equivalent plasma morphine levels in the 2 rat strains suggested that these differences in morphine sensitivity were unlikely to be due to strain-related differences in morphine pharmacokinetics. Although MOP expression in the ventrolateral periaqueductal gray (vlPAG) did not differ between WKY and SD rats, the vlPAG was identified as a key locus for the hyporesponsivity to MOP agonism in WKY rats in the formalin test. Moreover, morphine-induced effects on c-Fos (a marker of neuronal activity) in regions downstream of the vlPAG, namely, the rostral ventromedial medulla and lumbar spinal dorsal horn, were blunted in the WKY rats. Together, these findings suggest that a deficit in the MOP-induced recruitment of the descending inhibitory pain pathway may underlie hyperalgesia to noxious inflammatory pain in the WKY rat strain genetically predisposed to negative affect.
Predictors and prognoses of Willisian collateral failure during mechanical thrombectomy.
Scientific reports, 2020

During mechanical thrombectomy in the anterior cerebral circulation, thrombus embolization resulting in Willisian collateral failure may lead to critical stroke outcomes due to a shutdown of leptomeningeal collaterals. We hypothesized that the outcomes of dynamic Willisian collateral failure (DWF), induced during mechanical thrombectomy, would be associated with grave outcomes. We evaluated this hypothesis in consecutive patients, between January 2011 and May 2016, who underwent mechanical thrombectomy for anterior circulation occlusions, with an onset-to-puncture of 24 h. Patients with initial Willisian collateral failure (IWF) were identified first, with remaining patients classified into the DWF and Willisian collateral sparing (WCS) groups. Comparative and multivariable analyses were performed to predict grave outcomes (3-month modified Rankin Scale score of 5-6). Among 567 patients, 37 were in the IWF group, 38 in the DWF group, and 492 in the WCS group. Compared to the WCS and DWF groups, the IWF group had a higher baseline National Institute of Health Stroke Scale score and lower Alberta Stroke Program Early CT Score. The prevalence of grave outcomes was similarly high in the IWF (48.6%) and DWF (47.4%) groups, but lower in the WCS group (22.0%; p < 0.001). IWF and DWF were independent risk factors for a grave outcome.
Low temperature stimulation augments early wave component of somatosensory evoked response in humans and Macaca mulatta monkeys.
Pain, 1982

An early wave component of the scalp-recorded SER increases in amplitude when cold and electrical stimulation are combined. This change is accompanied by subjective reports of perceptual change in the intensity, domain or painfulness of the electrical stimulus in humans. Further results suggest that observation of the augmentation is dependent on normal functioning of both large and small peripheral fiber populations. This augmentation is also observed in Macaca mulatta monkeys. Under the same conditions, the spinal segmental SER is observed to obtain a new wave. This wave is time-locked to the electrical stimulus and has a latency longer than the earliest, but shorter than the latest traditional slow waves. The interaction of the cold and electrical stimuli to produce the cortical augmentation suggests the existence of a facilitatory mechanism. The level at which this operates and the mechanism through which it functions are discussed. The relationship of this augmentation to arousal phenomena is also examined.

The use of indocyanine green (ICG) dye has been proposed to allow the proper localization of endometriotic lesions during surgery. Our purpose is to offer an overview of near-infrared (NIR)-ICG in the surgical treatment of superficial peritoneal endometriosis and deep infiltrating endometriosis.
Body mass is positively associated with neural response to sweet taste, but not alcohol, among drinkers.
Behavioural brain research, 2017

Obesity is a large and growing public health concern, presenting enormous economic and health costs to individuals and society. A burgeoning literature demonstrates that overweight and obese individuals display different neural processing of rewarding stimuli, including caloric substances, as compared to healthy weight individuals. However, much extant research on the neurobiology of obesity has focused on addiction models, without highlighting potentially separable neural underpinnings of caloric intake versus substance use. The present research explores these differences by examining neural response to alcoholic beverages and a sweet non-alcoholic beverage, among a sample of individuals with varying weight status and patterns of alcohol use and misuse. Participants received tastes of a sweet beverage (litchi juice) and alcoholic beverages during fMRI scanning. When controlling for alcohol use, elevated weight status was associated with increased activation in response to sweet taste in regions including the cingulate cortex, hippocampus, precuneus, and fusiform gyrus. However, weight status was not associated with neural response to alcoholic beverages.
Numerosity adaptation partly depends on the allocation of implicit numerosity-contingent visuo-spatial attention.
Journal of vision, 2021

Like other perceptual attributes, numerosity is susceptible to adaptation. Nevertheless, it has never been fully investigated whether adaptation to numerosity is fully perceptual in nature or if it stems from the mixed influence of perception and attention. In the present work, we addressed this point throughout three separate experiments aiming at investigating the potential role played by visuo-spatial attentional mechanisms in shaping numerosity perception and adaptation. In Experiments 1 and 2, we showed that the magnitude of numerosity adaptation can be strongly influenced by the distribution of numerosity-contingent visuo-spatial attentional resources during the adaptation period. Results from Experiment 1 revealed a robust reduction of adaptation magnitude whenever a second numerical stimulus was presented in a diametrically opposite location from that of the adaptor, despite this second adapter being neutral as matched in numerosity with the following stimulus displayed in that location. In Experiment 2, we showed that this reduction in adaptation did not occur in cases where the second stimulus was not numerical, suggesting that attentional resources specifically related to numerosity information accounts for the results of Experiment 1. Finally, in Experiment 3, we showed that uninformative visuo-spatial cues shape numerosity discrimination judgments both at baseline and during adaptation. Taken together, our results seem to indicate that visuo-spatial attention plays a relevant role in numerosity perception and that adaptation to numerosity is actively influenced by this cognitive process.
