Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland 2016 Carol Davila University, Department of Surgery and Psychiatry

Structural Dichotomy Of The Mind; The Role Of Sexual Neuromodulators, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

The mind (mental function) and sexuality represent two distinct environmental functions, but which are supported within the brain by a common (somatic-autonomic) neurobiological substrate. As a consequence, mental function takes on autonomic characteristics from the sexual-autonomic system (like autonomy, duality), while sexual function takes on features from mental functioning (such as lateralization). In this paper we discuss the lateralized action of two classes of sexual neuromodulators: hormones and pheromones. This process of lateralization is assimilated with the structural dichotomy of the mind.

A relatively similar process but related to informational dichotomy of the mind will be presented in a forthcoming ...

The Substrate Of The Biopsychosocial Influences In The Carcinogenesis Of The Digestive Tract, Georgică C. Târtea, Cristina Florescu, Daniel Pirici, Daniel Caragea, Elena A. Târtea, Cristin C. Vere

Journal of Mind and Medical Sciences

Digestive cancer represents a severe public health problem, being one of the main causes of death. It is considered a multifactorial disease, with hereditary predisposition, environmental factors, and other factors involved in carcinogenesis. Both the evolution and the pathogenesis of digestive neoplasms remain incompletely elucidated. As a multifactorial disease, it can be approached by taking into account the biopsychosocial influences via enteric nervous system. Many peptides and non-peptides having a neurotransmitter role can be found in the enteric nervous system, which can influence the neoplastic process directly or indirectly by affecting some angiogenic, growth, and metastasis factors. However, neurotransmitters can ...


The Postfinasteride Syndrome; An Overview, David L. Rowland, Ion G. Motofei, Florian Popa, Vlad D. Constantin, Adriana Vasilache, Ioana Păunică, Cristian Bălălău, Georgeta P. Păunică, Petrisor Banu, Stana Păunică 2016 Valparaiso University, Department of Psychology

The Postfinasteride Syndrome; An Overview, David L. Rowland, Ion G. Motofei, Florian Popa, Vlad D. Constantin, Adriana Vasilache, Ioana Păunică, Cristian Bălălău, Georgeta P. Păunică, Petrisor Banu, Stana Păunică

Journal of Mind and Medical Sciences

As a 5-α reductase inhibitor, Finasteride has proven effective in ameliorating two conditions documented to be androgen dependent, namely male androgenic alopecia and benign prostatic hyperplasia. Therapeutic results are maintained as long as the drug is administered, with treatment cessation generally leading to the return of symptomatology for each condition. In addition, during the therapeutic phase, several adverse effects have been reported, some of which persist long or indefinitely after treatment cessation, known as “post-finasteride syndrome.”

Herein we present and discuss the most common finasteride side effects, along with a psycho-neuroendocrine rationale that could explain the persistence of many adverse ...


Neural Control Of Tongue Movements Across Effort Levels, Megan Rovang, Angela M. Dietsch 2016 University of Nebraska-Lincoln

Neural Control Of Tongue Movements Across Effort Levels, Megan Rovang, Angela M. Dietsch

UCARE Research Products

Background

A hallmark of Parkinson’s disease (PD) is a mismatch between the perceived effort and actual forces exerted during functional activities such as speech. Current evidence supports therapy to help reset this perception of effort, but the neurological underpinnings of such treatments are unclear. This study examined brain activity during tongue movements performed at varying levels of effort to determine (1) which brain areas are involved in each task, and (2) which areas, if any, scale in activation according to effort level. These results, considered with the neurological changes associated with PD, can be used to develop and refine ...


The Effect Of Training On Motoneuron Survival In Amyotrophic Lateral Sclerosis: Which Motoneuron Type Is Saved?, Sherif M. Elbasiouny, Jenna E. Schuster 2016 Wright State University - Main Campus

The Effect Of Training On Motoneuron Survival In Amyotrophic Lateral Sclerosis: Which Motoneuron Type Is Saved?, Sherif M. Elbasiouny, Jenna E. Schuster

Sherif M. Elbasiouny

Amyotrophic lateral sclerosis (ALS) is characterized by selective and progressive degeneration of motoneurons (MNs). Although the etiology of the disease is unknown, glutamate toxicity and reactive oxygen species toxicity have been strongly implicated in ALS pathophysiology, Training exercise has been proposed to provide a beneficial therapy during the early or late stages of ALS; however, some studies showed deleterious effects of exercise on survival in ALS.


Adult Spinal Motoneurones Are Not Hyperexcitable In A Mouse Model Of Inherited Amyotrophic Lateral Sclerosis, Nicolas Delestrée, Marin Manuel, Caroline Iglesias, Sherif M. Elbasiouny, C. J. Heckman, Daniel Zytnicki 2016 Wright State University - Main Campus

Adult Spinal Motoneurones Are Not Hyperexcitable In A Mouse Model Of Inherited Amyotrophic Lateral Sclerosis, Nicolas Delestrée, Marin Manuel, Caroline Iglesias, Sherif M. Elbasiouny, C. J. Heckman, Daniel Zytnicki

Sherif M. Elbasiouny

In amyotrophic lateral sclerosis (ALS), an adult onset disease in which there is progressive degeneration of motoneurones, it has been suggested that an intrinsic hyperexcitability of motoneurones (i.e. an increase in their firing rates), contributes to excitotoxicity and to disease onset. Here we show that there is no such intrinsic hyperexcitability in spinal motoneurones. Our studies were carried out in an adult mouse model of ALS with a mutated form of superoxide dismutase 1 around the time of the first muscle fibre denervations. We showed that the recruitment current, the voltage threshold for spiking and the frequency–intensity gain ...


Is Online Motor Control Really Impaired In Parkinson's Disease?, Kate E. Merritt 2016 The University of Western Ontario

Is Online Motor Control Really Impaired In Parkinson's Disease?, Kate E. Merritt

Electronic Thesis and Dissertation Repository

Patients with Parkinson’s disease (PD) are thought to be selectively impaired in consciously-mediated online automatic motor control, whereas the ability to perform subconscious online adjustments remains intact. This present study evaluates the hypothesis that the previously alleged deficits in online motor control in PD are not due to the consciousness of the correction, but rather are attributable to aspects of the prior experimental designs disproportionately penalizing patients for PD-related bradykinesia. Here, we implemented a modified traditional double-step paradigm to investigate consciously-mediated online motor control in PD, in a manner that would be unconfounded by disease-related bradykinesia. Further, we investigated ...


Closed-State Inactivation Involving An Internal Gate In Kv4.1 Channels Modulates Pore Blockade By Intracellular Quaternary Ammonium Ions., Jeffrey D. Fineberg, Tibor G. Szanto, Gyorgy Panyi, Manuel Covarrubias 2016 Thomas Jefferson University

Closed-State Inactivation Involving An Internal Gate In Kv4.1 Channels Modulates Pore Blockade By Intracellular Quaternary Ammonium Ions., Jeffrey D. Fineberg, Tibor G. Szanto, Gyorgy Panyi, Manuel Covarrubias

Department of Neuroscience

Voltage-gated K(+) (Kv) channel activation depends on interactions between voltage sensors and an intracellular activation gate that controls access to a central pore cavity. Here, we hypothesize that this gate is additionally responsible for closed-state inactivation (CSI) in Kv4.x channels. These Kv channels undergo CSI by a mechanism that is still poorly understood. To test the hypothesis, we deduced the state of the Kv4.1 channel intracellular gate by exploiting the trap-door paradigm of pore blockade by internally applied quaternary ammonium (QA) ions exhibiting slow blocking kinetics and high-affinity for a blocking site. We found that inactivation gating seemingly ...


Mechanical Reliability Of Implantable Polyimide-Based Magnetic Microactuators For Biofouling Removal, Christian G. Figueroa-Espada, Qi Yang, Hyowon Lee 2016 University of Puerto Rico, Mayaguez

Mechanical Reliability Of Implantable Polyimide-Based Magnetic Microactuators For Biofouling Removal, Christian G. Figueroa-Espada, Qi Yang, Hyowon Lee

The Summer Undergraduate Research Fellowship (SURF) Symposium

Hydrocephalus is a neurological disorder that typically requires a long-term implantation of a shunt system to manage its symptoms. These shunt systems are notorious for their extremely high failure rate. More than 40% of all implanted shunt systems fail within the first year of implantation. On average, 85% of all hydrocephalus patients with shunt systems undergo at least two shunt-revision surgeries within 10 years of implantation. A large portion of this high failure rate can be attributed to biofouling-related obstructions and infections. Previously, we developed flexible polyimide-based magnetic microactuators to remove obstructions formed on hydrocephalus shunts. To test the long-term ...


Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus 2016 The University of Western Ontario

Characterization And Personalization Of Botulinum Toxin Type A Therapy For Upper Limb Tremor In Parkinson Disease And Essential Tremor Patients Using Multi-Sensor Kinematic Technology, Olivia Samotus

Electronic Thesis and Dissertation Repository

Tremor commonly affects the upper extremities in essential tremor (ET) and Parkinson disease (PD) patients where many experience functional disability and ultimately seek therapy. As ET and PD tremor features overlap and clinical assessment is challenging due to its highly complex nature, misdiagnosis is common resulting in unsuitable therapies and prognosis. Current treatment options for ET and PD tremor include pharmacotherapy, focal therapy with botulinum toxin type A (BoNT-A) injections, and surgical interventions which provide modest relief of tremor. However, such therapies are commonly associated with significant adverse events and lack long-term efficacy and tolerability. Hence lack of standardized, objective ...


Neuroanatomical Maps And Taste Reactivity To Sweet, Umami, And Bitter Taste In The Pbn Of C57bl/6j Mice, Jennifer Marie Saputra 2016 University of Tennessee Health Science Center

Neuroanatomical Maps And Taste Reactivity To Sweet, Umami, And Bitter Taste In The Pbn Of C57bl/6j Mice, Jennifer Marie Saputra

Theses and Dissertations (ETD)

Humans can distinguish at least five different taste qualities, sour, salty, bitter, sweet, and umami (the savory taste of certain amino acids). In neuroscience research, behavioral testing is used to measure the ability of rodents (including inbred mice) to discriminate between the different taste qualities. Taste reactivity and two-bottle preference are behavioral tests that are utilized to investigate different aspects of taste. These tests involve either voluntary or forced consumption of taste stimuli, respectively. Either test can be used to infer the preference and palatability of the stimulus consumed by an animal.

In order to understand the basis of taste ...


Evaluating The Therapeutic Effect Of An Hsp90 Inhibitor In Mouse Models Of Alzheimer’S Disease, Bin Wang 2016 University of Tennessee Health Science Center

Evaluating The Therapeutic Effect Of An Hsp90 Inhibitor In Mouse Models Of Alzheimer’S Disease, Bin Wang

Theses and Dissertations (ETD)

The excessive accumulation of amyloid peptides (Aβ) represents one major pathological hallmark of Alzheimer’s disease (AD), which is most notably characterized by synaptic dysfunction. Strategies targeting heat shock protein 90 (Hsp90) inhibition have been widely investigated in the treatment of cancer for over two decades. Its application in the treatment of neurodegenerative diseases however, has emerged more recently in the last decade. The role of the Hsp90 chaperone in clearing misfolded protein aggregates has been well established (in vitro only), but its function in synaptic activity remains elusive.

In our study, we utilized a widely used Hsp90 inhibitor, 17-AAG ...


Repeated Zolpidem Treatment Effects On Sedative Tolerance, Withdrawal, Mrna Levels, And Protein Expression, Brittany T. Wright 2016 University of Tennessee Health Science Center

Repeated Zolpidem Treatment Effects On Sedative Tolerance, Withdrawal, Mrna Levels, And Protein Expression, Brittany T. Wright

Theses and Dissertations (ETD)

Zolpidem and benzodiazepines (BZs) potentiate the inhibitory action of gamma-Aminobutyric acid (GABA) by allosterically binding to GABAA receptors (GABAAR). Prolonged use of GABAAR positive allosteric modulators (PAM) can lead to behavioral tolerance, the diminished response to the same drug dose with repeated use, and withdrawal, a group of symptoms that occur due to abrupt end of drug treatment. Zolpidem is a short-acting, non-BZ GABAAR PAM whose potential for tolerance and withdrawal is unclear. Zolpidem demonstrates sedative efficacy similar to BZs and has become a main treatment of insomnia in lieu of BZs. Zolpidem replaced BZs due to lower incidences of ...

Martin Stephens, Ph.D.

The Expert Meeting on alternative methods for Botulinum neurotoxin (BoNT) potency testing was held at the BfR as the result of a decree from the German Federal Ministry of Food, Agriculture and Consumer Protection (BMELV), after it was informed by German state authorities about an increase in animal numbers being used in the LD50 potency test in mice for the purposes of BoNT potency testing. Ethical concerns have been raised in both Europe and the United States about the animal suffering involved in this type of testing, especially in the context of BoNT’s aesthetic applications. There had been increased ...

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse 2016 University of Pennsylvania Law School

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the neuroscientific ...


1st Place: The Effectiveness Of Yoga Therapy On An Adult, Post-Stroke Population: A Systematic Review (Final Research Paper), Baylor E. Hogan 2016 Chapman University

1st Place: The Effectiveness Of Yoga Therapy On An Adult, Post-Stroke Population: A Systematic Review (Final Research Paper), Baylor E. Hogan

Kevin and Tam Ross Undergraduate Research Prize

Objectives: The objectives of this paper are to (1) give a brief overview of stroke pathophysiology (2) outline yoga as a therapeutic strategy (3) present the current research on yoga rehabilitation for stroke (4) discuss the efficacy of yoga for chronic stroke.

Methods: Relevant terms were searched in PubMed, Web of Science, Academic OneFile, ScienceDirect, and Google Scholar electronic databases. Studies were excluded if they contained pediatric stroke, non-stroke neurological diseases, or subjects with comorbidities. Statistically significant data was extracted for the primary measures of nine trials.

Results: Four studies measured statistically significant outcomes (p<0.05). These included improvements in balance, independence, endurance, trait anxiety, fear of falling, self-efficacy, pain, strength, range of motion (ROM), activity, participation, and quality of life (QoL). Discussion: Lack of statistical significance in post-stroke depression (PSD) measures may be due to inadequate intervention length or a psychosocial cause of depression. Improvements in balance, flexibility, and strength from yoga participation permitted progress in disability and functionality. Finally, overall health-related quality of life (HRQL) is affected by the severity of mental disorders and physical disability. Yoga can have a positive effect in both domains and therefore, may improve HRQL.

Conclusion: Preliminary evidence suggests the ...


Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin 2016 University of South Florida

Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin

Graduate Theses and Dissertations

Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation ...
