Stable, Neuron-Specific Gene Expression In The Mouse Brain, Osama Ahmed, Kingsley M. Ekumi, Francesco V. Nardi, Gulimiheranmu Maisumu, Khaled Moussawi, Eric D. Lazartigues, Bo Liang, Abraam M. Yakoub

School of Medicine Faculty Publications

Gene delivery to, and expression in, the mouse brain is important for understanding gene functions in brain development and disease, or testing gene therapies. Here, we describe an approach to express a transgene in the mouse brain in a cell-type-specific manner. We use stereotaxic injection of a transgene-expressing adeno-associated virus into the mouse brain via the intracerebroventricular route. We demonstrate stable and sustained expression of the transgene in neurons of adult mouse brain, using a reporter gene driven by a neuron-specific promoter. This approach represents a rapid, simple, and cost-effective method for global gene expression in the mouse brain, in …

Adolescent Mental Health In The Twenty-First Century, Arthur Maerlander, Patricia Gail Bray

Center for Brain, Biology, and Behavior: Faculty Publications

Conclusion

Parents do not suddenly relinquish medical decision-making to their children and are a vital part of a process construed within the framework of consent and confidentiality laws. In the transition period from childhood to adulthood, adolescents develop unique healthcare needs and concerns at the very time they are gaining autonomy from their parents. Adolescents progress from being recipients of decisions about their care to gradually becoming active participants in their healthcare and emerge as a primary partner in medical decision-making. Building a strong therapeutic alliance with young people can help them become responsible healthcare decision-makers.

Yet while “healthcare,” including …

Associations Of Sex And Sport Contact‑Level With Recovery Timelines Among Collegiate Athletes With Sport‑Related Concussion, Bernadette A. D'Alonzo, Andrea L. C. Schneider, Ian J. Barnett, Christina L. Master, Abigail C. Bretzin, Douglas J. Wiebe, Ivy League-Big Ten Epidemiology Of Concussion Study Investigators

Center for Brain, Biology, and Behavior: Faculty Publications

Background

Growing interest has motivated recent studies to examine differences in recovery after sportrelated concussion (SRC) by sex. However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines. This study aimed to investigate whether concussion recovery trajectories differ by sex, considering a priori clinical and demographic covariates, and accounting for the sequence of recovery outcomes. Our secondary question was whether sport contact-level modifies the relationship between sex and time to outcomes. …

Different Spectrum Of Space Radiation Induced Cognitive Impairments In Radiation-Naïve And Adapted Rats, Richard A. Britten, Arriyam S. Fesshaye, Alyssa Tidmore, Ella N. Tamgue, Paola A. Alvarado-Arriaga

Center for Integrative Neuroscience and Inflammatory Diseases (CINID) Faculty Publications

NASA's decision to resume manned deep space mission, first to the Moon and then Mars, necessitated a detailed assessment of the potential health effects that astronauts may experience on long-duration missions. Multiple studies suggest that there may be significant space radiation (SR)-induced impairment of neurocognitive processes, including advanced executive functions. However, given the multitude of SR-induced changes in the CNS, it is possible that completely different SR-induced sequelae will be induced in previously exposed individuals. Thus, current risk estimates are likely to be pertinent only for the early stages of a deep space mission, and even then only for astronauts …

Methods: A quality improvement project that included a fall bundle was implemented in a primary clinic. A …

Characterization Of Bowel Dysfunction After Spinal Cord Injury In Mice, Olivia Wireman

Theses and Dissertations--Physiology

Most individuals who suffer a spinal cord injury (SCI) will experience some form of bowel dysfunction. Trauma to the spinal cord can result in severe constipation and/or incontinence, otherwise known as neurogenic bowel. Constipation requires extensive bowel routines typically involving the help of another person. Still, many living with SCI are hospitalized due to bowel complications such as fecal impaction. While neurogenic bowel has been well characterized in the clinic, pre-clinical models of neurogenic bowel after SCI are still in development. Most pre-clinical studies in bowel dysfunction after SCI are published in rat models. Studies existing in mice, to our …

Mathematics & Statistics Faculty Publications

One of the major neuropathological consequences of traumatic brain injury (TBI) is intracranial hemorrhage (ICH), which requires swift diagnosis to avert perilous outcomes. We present a new automatic hemorrhage segmentation technique via curriculum-based semi-supervised learning. It employs a pre-trained lightweight encoder-decoder framework (MobileNetV2) on labeled and unlabeled data. The model integrates consistency regularization for improved generalization, offering steady predictions from original and augmented versions of unlabeled data. The training procedure employs curriculum learning to progressively train the model at diverse complexity levels. We utilize the PhysioNet dataset to train and evaluate the proposed approach. The performance results surpass those of …

Sex Differences In The Association Between Cardiac Vagal Control And The Effects Of Baroreflex Afferents On Behavior, Xiao Yang, Jacob Chaney, Aaron S. David, Fang Fang

Psychology Faculty Publications

Background: Cardiovascular disease (CVD) is the leading cause of mortality and disability worldwide. While sex differences in CVD have been well documented, the physiological mechanisms of those sex differences remain unclear. As important components of the cardiovascular system, cardiac vagal control and baroreflex serve as mechanisms of sex differences in CVD and are modifiable factors for gender-specific CVD preventions. Methods: Ninety-four healthy adults (18–44 years of age; M_age = 21.09 years; 46 female) were recruited to complete the assessments of heart rate variability (HRV) at a resting baseline and the cardiac timing effect on an R-wave-locked reaction time (RT) …

Subconcussive blast exposure has been shown to alter neurological functioning. However, the extent to which neurological dysfunction persists after blast exposure is unknown. This longitudinal study examined the potential short- and long-term effects of repeated subconcussive blast exposure on neuromotor performance from heavy weapons training in military personnel. A total of 214 participants were assessed; 137 were exposed to repeated subconcussive blasts and 77 were not exposed to blasts (controls). Participants completed a short stepping-in-place task while an Android smartphone app placed on their thigh recorded movement kinematics. We showed acute suppression of neuromotor variability 6 h after subconcussive blast …

End Of Life In The Ed – Brain Death And Organ Transplantation, Madison Cohen, Donald Penney

The Journal of Integrated Primary Care

Every year thousands of Americans die awaiting an organ transplant. While our knowledge and experience with organ transplantation has only improved, organ availability continues to be a major issue due to a lack of suitable donor organs. A large population of organ donors are those who have been clinically diagnosed as brain dead. Brain death is defined as the irreversible loss of all brain and brainstem functions. Despite brainstem functions being lost, mechanical ventilation and perfusion techniques allow for proper organ maintenance. This gives brain-dead individuals a unique opportunity to serve as multiple organ donors. However, due to mistrust of …

Theses & Dissertations

Heart failure is a prevalent and debilitating disease associated with high morbidity and mortality rates worldwide and is the leading cause of death in the United States. While various therapeutic strategies have been developed and approved to manage heart failure, exploration of novel targets and mechanisms are essential for improving patient outcomes. This thesis investigates the therapeutic potential of the central activation of opioid receptor-like 1 (ORL-1) by nociceptin in a rodent heart failure model.

Furthermore, this study aims to elucidate the central mechanisms underlying nociceptin induced cardiovascular and renal effects in heart failure. This involves investigating neuronal pathways and …

Cytomegalovirus And Varicella Zoster Virus Coinfection-Associated Central Hypoventilation Syndrome (Ondine's Curse), Marine Isakadze, Benjamin Zwain, Alan J. Velander, Jesus Lovera

School of Medicine Faculty Publications

Central hypoventilation syndrome (CHS) is a rare condition resulting from damage to the respiratory centers in the central nervous system (CNS). It can be congenital or acquired and can cause hypoventilation, inadequate gas exchange, and respiratory failure, often during sleep but sometimes even while awake. CHS can lead to respiratory failure and life-threatening complications if not identified promptly. In this report, we present a rare case of a patient with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), who developed CHS likely due to an opportunistic infection by cytomegalovirus (CMV) and varicella zoster virus (VZV), manifesting as a lesion in the …

Center for Brain, Biology, and Behavior: Faculty Publications

Background Latina mothers have been especially affected by the pandemic and historically exhibit high rates of depression and anxiety. However, few longitudinal studies have assessed the effect of the pandemic on this vulnerable population. We hypothesized that COVID-19-related stressors would associate with psychological distress among Latina mothers across the first year of the pandemic.

Methods We investigated COVID-19-related impact, stigma, and fears across two critical time points and changes in these measures in relation to changes in maternal anxiety and depression among mothers of Mexican descent living in Southern California (n=152). Surveys were administered within 5–16 weeks of …

Spasms would occur 4-5 times/day, lasting minutes to hours despite a 2-year course of therapeutic and pharmacological interventions. Due to treatment refraction, 6 uniformly spaced botulinum toxin type A (BTX-A) injections were placed per side, using electromyography for audible intramuscular syringe placement confirmation, while visual confirmation was made via ultrasound. During the initial trial, 6 evenly spaced injections were performed bilaterally, uniformly distributing 80U/side. Injections began bilaterally just medial to the junction of the inferior rib cage border/ anterior axillary line and progressed …

Brain Microvascular Endothelial Cells Possess A Second Cilium That Arises From The Daughter Centriole, Karthikeyan Thirugnanam, Ankan Gupta, Francisco Nunez, Shubhangi Prabhudesai, Amy Y. Pan, Surya M. Nauli, Ramani Ramchandran

Pharmacy Faculty Articles and Research

Primary cilia from the brain microvascular endothelial cells (ECs) are specialized cell-surface organelles involved in mediating sensory perception, cell signaling, and vascular stability. Immunofluorescence (IF) analysis of human primary brain microvascular ECs reveals two cilia per cell. To confirm the in vitro observation of the two-cilia phenotype in human primary brain ECs, ECs isolated from mouse brain were cultured and stained for cilium. Indeed, brain ECs from a ciliopathic mouse (polycystic kidney disease or Pkd2−/−) also possess more than one cilium. Primary cilium emerges from the mother centriole. Centriole analysis by IF suggests that in brain ECs, markers …

Traumatic Stress-Induced Increases In Anxiety-Like Behavior And Alcohol Self-Administration Are Mediated By Central Amygdala Crf1 Neurons That Project To The Lateral Hypothalamus, Marcus M. Weera, Daniel A. Webster, Rosetta S. Shackett, Federica Benvenuti, Jason W. Middleton, Nicholas W. Gilpin

School of Graduate Studies Faculty Publications

Avoidance stress coping, defined as persistent internal and/or external avoidance of stress-related stimuli, is a key feature of anxiety- and stress-related disorders, and contributes to increases in alcohol misuse after stress exposure. Previous work using a rat model of predator odor stress avoidance identified corticotropin-releasing factor (CRF) signaling via CRF type-1 receptors (CRF1) in the central amygdala (CeA), as well as CeA projections to the lateral hypothalamus (LH) as key mediators of conditioned avoidance of stress-paired contexts and/or increased alcohol drinking after stress. Here, we report that CRF1-expressing CeA cells that project to the LH are preferentially activated in male …

Blair, Matthew Dobbertin, Jaimie Elowsky, Johannah Bashford‑Largo, Ahria J. Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Background

Conduct disorder (CD) involves a group of behavioral and emotional problems that usually begins during childhood or adolescence. Structural brain alterations have been observed in CD, including the amygdala, insula, ventrolateral and medial prefrontal cortex, anterior cingulate cortex, and fusiform gyrus. The current study developed a multivariate generalized linear model (GLM) to differentiate adolescents with CD from typically developing (TD) adolescents in terms of grey matter volume (GMV).

Methods

The whole‐brain structural MRI data were collected from 96 adolescents with CD (mean age = 16.188 ± 1.259 years; mean IQ = 104.292 ± 8.107 ; 63 males) and 90 …

Prevalent Distribution Of Conscious Processes On Either Side Of The Brain, Sohail Adnan, Mubasher Shah, Muhammad Fateen Rashed, Sadaf Nawab

Journal of Mind and Medical Sciences

Objectives. The brain has an intrinsic tendency for the lateralization of its functions. For instance, the left hemisphere assists in the comprehension and motor expression of language. What remains uncertain is whether conscious processes are also more prevalent in one hemisphere of the brain than the other. The epistemic goal of this research was to address this particular issue. Materials and Methods. We observed the rare pathological event of proximal occlusion of the middle cerebral artery (MCA), which halts blood flow to the central two-thirds of a hemisphere, and examined its effects on consciousness. We aggregated individual scores for eyes-opening …

Ca2+-Regulated Expression Of High Affinity Methylaminoisobutryic Acid Transport In Hippocampal Neurons Inhibited By Riluzole And Novel Neuroprotective Aminothiazoles, Jeffrey D. Erickson, Thomas Kyllo, Heike Wulff

School of Medicine Faculty Publications

High affinity methylaminoisobutyric acid(MeAIB)/glutamine(Gln) transport activity regulated by neuronal firing occurs at the plasma membrane in mature rat hippocampal neuron-enriched cultures. Spontaneous Ca2+-regulated transport activity was similarly inhibited by riluzole, a benzothiazole anticonvulsant agent, and by novel naphthalenyl substituted aminothiazole derivatives such as SKA-378. Here, we report that spontaneous transport activity is stimulated by 4-aminopyridine (4-AP) and that phorbol-myristate acetate (PMA) increases high K+ stimulated transport activity that is inhibited by staurosporine. 4-AP-stimulated spontaneous and PMA-stimulated high K+-induced transport is not present at 7 days in vitro (DIV) and is maximal by DIV∼21. The relative affinity for MeAIB is similar …

Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology, and Behavior: Faculty Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

A Neurodevelopmental Perspective To Improve Innovation In Preventive Treatment Of Substance Use Disorders, Ismael Perez, John Vandeberg, Mario Gil

Research Symposium

Background: Midbrain dopaminergic neurons have been associated with substance use disorders (Blaess & Ang, 2015). Understanding their neurodevelopment during early stages of life is fundamental for innovating preventive care treatments. The animal model Monodelphis domestica has been proposed as an excellent candidate to study neurodevelopmental changes due to the ease of access to see changes in their embryonic development (Mate et al., 1994). The purpose of our study is to inform how brain cells, including and especially dopaminergic neurons, mature by quantifying their number during early development. Additionally, the study aims to compare different midbrain areas and track neurodevelopmental changes …

Synlight: A Bicistronic Strategy For Simultaneous Active Zone And Cell Labeling In The Drosophila Nervous System, Michael A. Aimino, Jesse Humenik, Michael J. Parisi, Juan Carlos Duhart, Timothy J. Mosca

Farber Institute for Neuroscience Faculty Papers

At synapses, chemical neurotransmission mediates the exchange of information between neurons, leading to complex movement, behaviors, and stimulus processing. The immense number and variety of neurons within the nervous system make discerning individual neuron populations difficult, necessitating the development of advanced neuronal labeling techniques. In Drosophila, Bruchpilot-Short and mCD8-GFP, which label presynaptic active zones and neuronal membranes, respectively, have been widely used to study synapse development and organization. This labeling is often achieved via the expression of 2 independent constructs by a single binary expression system, but expression can weaken when multiple transgenes are expressed by a single driver. Recent …

Acute Ethanol Modulates Synaptic Inhibition In The Basolateral Amygdala Via Rapid Nlrp3 Inflammasome Activation And Regulates Anxiety-Like Behavior In Rats, Soumyabrata Munshi, Lucas Albrechet-Souza, Raoni Conceição Dos-Santos, Claire E. Stelly, Maria E. Secci, Nicholas W. Gilpin, Jeffrey G. Tasker

School of Graduate Studies Faculty Publications

Chronic alcohol exposure leads to a neuroinflammatory response involving activation of the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome and pro-inflammatory cytokine production. Acute ethanol (EtOH) exposure activates GABAergic synapses in the central and basolateral amygdala (BLA) ex vivo, but whether this rapid modulation of synaptic inhibition is due to an acute inflammatory response and alters anxiety-like behavior in male and female animals is not known. Here, we tested the hypotheses that acute EtOH facilitates inhibitory synaptic transmission in the BLA by activating the NLRP3 inflammasome-dependent acute inflammatory response, that the alcohol-induced increase in inhibition is cell type- and …

Integrated Inflammatory Signaling Landscape Response After Delivering Elovanoid Free-Fatty-Acid Precursors Leading To Experimental Stroke Neuroprotection, Madigan M. Reid, Ludmila Belayev, Larissa Khoutorova, Pranab K. Mukherjee, Andre Obenaus, Kierany Shelvin, Stacey Knowles, Sung Ha Hong, Nicolas G. Bazan

School of Graduate Studies Faculty Publications

Despite efforts to identify modulatory neuroprotective mechanisms of damaging ischemic stroke cascade signaling, a void remains on an effective potential therapeutic. The present study defines neuroprotection by very long-chain polyunsaturated fatty acid (VLC-PUFA) Elovanoid (ELV) precursors C-32:6 and C-34:6 delivered intranasally following experimental ischemic stroke. We demonstrate that these precursors improved neurological deficit, decreased T2WI lesion volume, and increased SMI-71 positive blood vessels and NeuN positive neurons, indicating blood–brain barrier (BBB) protection and neurogenesis modulated by the free fatty acids (FFAs) C-32:6 and C-34:6. Gene expression revealed increased anti-inflammatory and pro-homeostatic genes and decreases in expression of pro-inflammatory genes in …

Assessing Blood Oxygen Level–Dependent Signal Variability As A Biomarker Of Brain Injury In Sport-Related Concussion, Evan D. Anderson, Tanveer Talukdar, Grace Goodwin, Valentina Di Pietro, Kamal M. Yakoub, Christopher E. Zwilling, David Davies, Antonio Belli, Aron K. Barbey

Center for Brain, Biology, and Behavior: Faculty Publications

Mild traumatic brain injury is a complex neurological disorder of significant concern among athletes who play contact sports. Athletes who sustain sport-related concussion typically undergo physical examination and neurocognitive evaluation to determine injury severity and return-to-play status. However, traumatic disruption to neurometabolic processes can occur with minimal detectable anatomic pathology or neurocognitive alteration, increasing the risk that athletes may be cleared for return-to-play during a vulnerable period and receive a repetitive injury. This underscores the need for sensitive functional neuroimaging methods to detect altered cerebral physiology in concussed athletes. The present study compared the efficacy of Immediate Post-concussion Assessment and …

Identification Of Structural Brain Alterations In Adolescents With Depressive Symptomatology, J. Bashford‑Largo, R. James R. Blair, Karina S. Blair, Matthew Dobbertin, Ahria Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …
