Between The Entrepreneurial Impetus For Higher Profits And Consumer Rights Or Types Of Unfair And Misleading Commercial Practices: Insights From Bulgaria, Silviya Atanasova Topleva

International Journal on Consumer Law and Practice

The application of unfair misleading commercial practices affects the economic interests of consumers, threatening legal security and the achievement of market equilibrium. In response to these imbalances, the law builds a solid regulatory network for consumer protection. In the codification of the protection of consumer interests from unfair commercial practices, an important place is occupied by secondary legislation of the EU, and in particular Directive 2005/29/EC concerning unfair business-to-consumer commercial practices in the internal market. The article presents a classification of the types of unfair misleading commercial practices based on the regulatory framework at the European and national level. The …

The Impact On Psychologists In California Of The Rapid Shift To Teletherapy Due To The Covid-19 Pandemic In March 2020, Oriana Mcgee

Antioch University Dissertations & Theses

In March 2020, virtually overnight, in-person interactions shifted to online or other remote realms due to the governor of California's lock-down orders in response to the COVID-19 pandemic. At the same time, the need for mental health services including psychotherapy skyrocketed. Psychologists in California met this overwhelming demand by adapting to the challenges of the moment and embracing teletherapy, a relatively new mode of therapy for most practitioners at that time. Many studies were launched to capture real-time data about mental health workers' shift to providing remote and online services; however, most of these studies were focused on practitioners' experiences …

The Legal Framework For The Protection Of Victims Of The Worst Forms Of Child Labour In Agriculture In Ghana: A Human Rights Based Approach, Ruby Akua Aglagoh

Theses: Doctorates and Masters

Child labour is prevalent in Ghana, especially in the agriculture industry where children engage in work that is harmful to their health, morals, and safety. Such harmful work has been defined by the ILO Convention No. 182 on the Worst Forms of Child Labour, 1999 as constituting the worst forms of child labour. These children have human rights stated in the laws of Ghana but have become victims of human rights violations because they cannot access the protections provided for under the international conventions and national laws of Ghana.

Using doctrinal legal research, this thesis reviews the legal framework of …

A Wreck Of Seabirds: Entrapment And Isolation Within The Australian Coastal Gothic Landscape, Karleah May Olson

Theses: Doctorates and Masters

This thesis explores the concepts of entrapment and isolation as they relate to the Australian Gothic literary mode and coastal landscapes. It does so through a creative work, a novel entitled A Wreck of Seabirds, and an accompanying exegesis, which examines these concepts alongside the shift of the Gothic to Australian landscapes and ultimately to coastal settings, and their representation in fiction. It examines ways in which elements and tropes of the Gothic are utilized in Australian Coastal fiction, particularly through depictions and metaphors of entrapment and isolation. A Wreck of Seabirds is an Australian Coastal Gothic novel set in …

Tfeb-Vacuolar Atpase Signaling Regulates Lysosomal Function And Microglial Activation In Tauopathy, Baiping Wang, Heidi Martini-Stoica, Chuangye Qi, Tzu-Chiao Lu, Shuo Wang, Wen Xiong, Yanyan Qi, Yin Xu, Marco Sardiello, Hongjie Li, Hui Zheng

Center on Aging Staff Publications

Transcription factor EB (TFEB) mediates gene expression through binding to the coordinated lysosome expression and regulation (CLEAR) sequence. TFEB targets include subunits of the vacuolar ATPase (v-ATPase), which are essential for lysosome acidification. Single-nucleus RNA sequencing of wild-type and PS19 (Tau) transgenic mice expressing the P301S mutant tau identified three unique microglia subclusters in Tau mice that were associated with heightened lysosome and immune pathway genes. To explore the lysosome-immune relationship, we specifically disrupted the TFEB-v-ATPase signaling by creating a knock-in mouse line in which the CLEAR sequence of one of the v-ATPase subunits, Atp6v1h, was mutated. CLEAR mutant exhibited …

Faculty, Staff and Students Publications

Mantle cell lymphoma (MCL) has a poor prognosis and high relapse rates despite current therapies, necessitating novel treatment regimens. Inhibition of SRC-3 show effectiveness in vivo and in vitro in other B cell lymphomas. Additionally, previous studies have shown that SRC-3 is highly expressed in the lymph nodes of B cell non-Hodgkin's lymphoma patients, suggesting SRC-3 may play a role in the progression of B cell lymphoma. This study aimed to investigate novel SRC-3 inhibitors, SI-10 and SI-12, in mantle cell lymphoma. The cytotoxic effects of SI-10 and SI-12 were evaluated in vitro and demonstrated dose-dependent cytotoxicity in a panel …

Sle1 and Fas^lpr are two lupus susceptibility loci that lead to manifestations of systemic lupus erythematosus. To evaluate the dosage effects of Fas^lpr in determining cellular and serological phenotypes associated with lupus, we developed a new C57BL/6 (B6) congenic lupus strain, B6.Sle1/Sle1.Fas^lpr/+ (Sle1homo.lprhet) and compared it with B6.Fas^lpr/lpr (lprhomo), B6.Sle1/Sle1 (Sle1homo), and B6.Sle1/Sle1.Fas^lpr/lpr (Sle1homo.lprhomo) strains. Whereas Sle1homo.lprhomo mice exhibited profound lymphoproliferation and early mortality, Sle1homo.lprhet mice had a lifespan comparable to B6 mice, with no evidence of splenomegaly or lymphadenopathy. Compared to B6 monogenic lupus strains, Sle1homo.lprhet mice exhibited significantly …

Adipose Tissue Lymphocytes And Obesity, Feng Gao, Benjamin Litchfield, Huaizhu Wu

Faculty, Staff and Students Publications

Obesity is associated with chronic inflammation in adipose tissue (AT), mainly evidenced by infiltration and phenotypic changes of various types of immune cells. Macrophages are the major innate immune cells and represent the predominant immune cell population within AT. Lymphocytes, including T cells and B cells, are adaptive immune cells and constitute another important immune cell population in AT. In obesity, CD8+ effector memory T cells, CD4+ Th1 cells, and B2 cells are increased in AT and promote AT inflammation, while regulatory T cells and Th2 cells, which usually function as immune regulatory or type 2 inflammatory cells, are reduced …

Ethical Considerations For Integrating Multimodal Computer Perception And Neurotechnology, Meghan E Hurley, Anika Sonig, John Herrington, Eric A Storch, Gabriel Lázaro-Muñoz, Jennifer Blumenthal-Barby, Kristin Kostick-Quenet

Center for Medical Ethics and Health Policy Staff Publications

Background: Artificial intelligence (AI)-based computer perception technologies (e.g., digital phenotyping and affective computing) promise to transform clinical approaches to personalized care in psychiatry and beyond by offering more objective measures of emotional states and behavior, enabling precision treatment, diagnosis, and symptom monitoring. At the same time, passive and continuous nature by which they often collect data from patients in non-clinical settings raises ethical issues related to privacy and self-determination. Little is known about how such concerns may be exacerbated by the integration of neural data, as parallel advances in computer perception, AI, and neurotechnology enable new insights into subjective states. …

Background:

Although most individuals effectively control herpesvirus infections, some suffer from severe and/or recurrent infections. A subset of these patients possess defects in NK cells, lymphocytes which recognize and lyse herpesvirus-infected cells; however, the genetic etiology is rarely diagnosed. PLCG2 encodes a signaling protein in NK cell and B cell signaling. Dominant-negative or gain-of-function variants in PLCG2 cause cold urticaria, antibody deficiency, and autoinflammation. However, loss-of-function variants and haploinsufficiency have not been reported to date.

Objective:

We aimed to identify the genetic cause of NK cell immunodeficiency in two families, and herein describe the functional consequences of two novel loss-of-function …

Noncoding DNA is central to our understanding of human gene regulation and complex diseases1,2, and measuring the evolutionary sequence constraint can establish the functional relevance of putative regulatory elements in the human genome3–9. Identifying the genomic elements that have become constrained specifically in primates has been hampered by the faster evolution of noncoding DNA compared to protein-coding DNA10, the relatively short timescales separating primate species11, and the previously limited availability of whole-genome sequences12. Here we construct a whole-genome alignment of 239 species, representing nearly half of …

While loss-of-function (LoF) variants in KCNQ2 are associated with a spectrum of neonatal-onset epilepsies, gain-of-function (GoF) variants cause a more complex phenotype that precludes neonatal-onset epilepsy. In the present work, the clinical features of three patients carrying a de novo KCNQ2 Y141N (n = 1) or G239S variant (n = 2) respectively, are described. All three patients had a mild global developmental delay, with prominent language deficits, and strong activation of interictal epileptic activity during sleep. Epileptic seizures were not reported. The absence of neonatal seizures suggested a GoF effect and prompted functional testing of the variants. In vitro whole-cell …

BACKGROUND: Pre-neutrophils, while developing in the bone marrow, transcribe the Inhba gene and synthesize Activin-A protein, which they store and release at the earliest stage of their activation in the periphery. However, the role of neutrophil-derived Activin-A is not completely understood.

METHODS:To address this issue, we developed a neutrophil-specific Activin-A-deficient animal model (S100a8-Cre/Inhba fl/fl mice) and analyzed the immune response to Influenza A virus (IAV) infection. More specifically, evaluation of body weight and lung mechanics, molecular and cellular analyses of bronchoalveolar lavage fluids, flow cytometry and cell sorting of lung cells, as well as histopathological analysis of lung tissues, …

Developing A Pathway To Clinical Trials For Cacna1a-Related Epilepsies: A Patient Organization Perspective, Pangkong M Fox, Sunitha Malepati, Lisa Manaster, Elsa Rossignol, Jeffrey L Noebels

Faculty, Staff and Students Publications

CACNA1A-related disorders are rare neurodevelopmental disorders linked to variants in the CACNA1A gene. This gene encodes the α1 subunit of the P/Q-type calcium channel Cav2.1, which is globally expressed in the brain and crucial for fast synaptic neurotransmission. The broad spectrum of CACNA1A-related neurological disorders includes developmental and epileptic encephalopathies, familial hemiplegic migraine type 1, episodic ataxia type 2, spinocerebellar ataxia type 6, together with unclassified presentations with developmental delay, ataxia, intellectual disability, autism spectrum disorder, and language impairment. The severity of each disorder is also highly variable. The spectrum of CACNA1A-related seizures is broad across both loss-of-function and gain-of-function …

BACKGROUND: Pathogenic variants in the centrosome protein (CEP) family have been implicated in primary microcephaly, Seckel syndrome, and classical ciliopathies. However, most CEP genes remain unlinked to specific Mendelian genetic diseases in humans. We sought to explore the roles of CEP295 in human pathology.

METHODS: Whole-exome sequencing was performed to screen for pathogenic variants in patients with severe microcephaly. Patient-derived fibroblasts and CEP295-depleted U2OS and RPE1 cells were used to clarify the underlying pathomechanisms, including centriole/centrosome development, cell cycle and proliferation changes, and ciliogenesis. Complementary experiments using CEP295 mRNA were performed to determine the pathogenicity of the identified missense variant. …

BACKGROUND: Parkinson's disease (PD) is a complex neurodegenerative disorder impacting everyday function and quality of life. Rehabilitation plays a crucial role in improving symptoms, function, and quality of life and reducing disability, particularly given the lack of disease-modifying agents and limitations of medications and surgical therapies. However, rehabilitative care is under-recognized and under-utilized in PD and often only utilized in later disease stages, despite research and guidelines demonstrating its positive effects. Currently, there is a lack of consensus regarding fundamental topics related to rehabilitative services in PD.

OBJECTIVE: The goal of the international Parkinson's Foundation Rehabilitation Medicine Task Force was …

Ultradian Rhythms In Accelerometric And Autonomic Data Vary Based On Seizure Occurrence In Paediatric Epilepsy Patients, Solveig Vieluf, Sarah Cantley, Vaishnav Krishnan, Tobias Loddenkemper

Faculty, Staff and Students Publications

Ultradian rhythms are physiological oscillations that resonate with period lengths shorter than 24 hours. This study examined the expression of ultradian rhythms in patients with epilepsy, a disease defined by an enduring seizure risk that may vary cyclically. Using a wearable device, we recorded heart rate, body temperature, electrodermal activity and limb accelerometry in patients admitted to the paediatric epilepsy monitoring unit. In our case–control design, we included recordings from 29 patients with tonic–clonic seizures and 29 non-seizing controls. We spectrally decomposed each signal to identify cycle lengths of interest and compared average spectral power- and period-related markers between groups. …

A Dual Target Molecular Magnetic Resonance Imaging Probe For Noninvasive Profiling Of Pathologic Alpha-Synuclein And Microgliosis In A Mouse Model Of Parkinson’S Disease, Xianwei Sun, Andrew Badachhape, Prajwal Bhandari, Jeannie Chin, Ananth Annapragada, Eric Tanifum

Faculty, Staff and Students Publications

The pathogenesis of Parkinson’s disease (PD) is characterized by progressive deposition of alpha-synuclein (α-syn) aggregates in dopaminergic neurons and neuroinflammation. Noninvasive in vivo imaging of α-syn aggregate accumulation and neuroinflammation can elicit the underlying mechanisms involved in disease progression and facilitate the development of effective treatment as well as disease diagnosis and prognosis. Here we present a novel approach to simultaneously profile α-syn aggregation and reactive microgliosis in vivo, by targeting oligomeric α-syn in cerebrospinal fluid with nanoparticle bearing a magnetic resonance imaging (MRI), contrast payload. In this proof-of-concept report we demonstrate, in vitro, that microglia and neuroblastoma …

Night-Time Neuronal Activation Of Cluster N In A North American Songbird\, Jennifer Rudolf, Natalie Philipello, Tamara Fleihan, J David Dickman, Kira E Delmore

Faculty, Staff and Students Publications

Night-migrating songbirds utilize the Earth's magnetic field to help navigate to and from their breeding sites each year. A region of the avian forebrain called Cluster N has been shown to be activated during night migratory behavior and it has been implicated in processing geomagnetic information. Previous studies with night-migratory European songbirds have shown that neuronal activity at Cluster N is higher at night than during the day. Comparable work in North American migrants has only been performed in one species of swallows, so extension of examination for Cluster N in other migratory birds is needed. In addition, it is …

Cisplatin Vestibulotoxicity: A Current Review, Tamara Fleihan, Marc Elie Nader, J David Dickman

Faculty, Staff and Students Publications

Cisplatin, a commonly used chemotherapy drug, is well-established for its ototoxic effects, primarily attributed to the damage it inflicts on cochlear hair cells. However, its impact on the vestibular system remains inadequately understood. Here, we provide a comprehensive review of existing literature concerning cisplatin-induced vestibulotoxicity. Animal studies have shown that cisplatin induces a vestibular hair cell loss that is dose-dependent, with the severity of damage also varying according to the route of administration. Notably, intratympanic and systemic injections in animal models have manifested significant damage primarily to utricular hair cells, with a lesser degree of damage observed for the other …

Scan-Less Microscopy Based On Acousto-Optic Encoded Illumination, Andrea Marchese, Pietro Ricci, Peter Saggau, Martí Duocastella

Faculty, Staff and Students Publications

Several optical microscopy methods are now available for characterizing scientific and industrial processes at sub-micron resolution. However, they are often ill-suited for imaging rapid events. Limited by the trade-off between camera frame-rate and sensitivity, or the need for mechanical scanning, current microscopes are optimized for imaging at hundreds of frames-per-second (fps), well-below what is needed in processes such as neuronal signaling or moving parts in manufacturing lines. Here, we present a scan-less technology that allows sub-micrometric imaging at thousands of fps. It is based on combining a single-pixel camera with parallelized encoded illumination. We use two acousto-optic deflectors (AODs) placed …

High-Fat Diets Promote Peritoneal Inflammation And Augment Endometriosis-Associated Abdominal Hyperalgesia, Tristin Herup-Wheeler, Mingxin Shi, Madeleine E Harvey, Chandni Talwar, Ramakrishna Kommagani, James A Maclean, Kanako Hayashi

Faculty, Staff and Students Publications

Immune dysfunction is one of the central components in the development and progression of endometriosis by establishing a chronic inflammatory environment. Western-style high-fat diets (HFD) have been linked to greater systemic inflammation to cause metabolic and chronic inflammatory diseases, and are also considered an environmental risk factor for gynecologic diseases. Here, we aimed to examine how HFD cause an inflammatory environment in endometriosis and discern their contribution to endometriotic-associated hyperalgesia. Our results showed that HFD-induced obesity enhanced abdominal hyperalgesia that was induced by endometriotic lesions. Peritoneal inflammatory macrophages and cytokine levels increased by lesion induction were elevated by chronic exposure …

A Novel System To Culture Human Intestinal Organoids Under Physiological Oxygen Content To Study Microbial-Host Interaction, Tatiana Y Fofanova, Umesh C Karandikar, Jennifer M Auchtung, Reid L Wilson, Antonio J Valentin, Robert A Britton, K Jane Grande-Allen, Mary K Estes, Kristi Hoffman, Sashirekha Ramani, Christopher J Stewart, Joseph F Petrosino

Mechanistic investigation of host-microbe interactions in the human gut are hindered by difficulty of co-culturing microbes with intestinal epithelial cells. On one hand the gut bacteria are a mix of facultative, aerotolerant or obligate anaerobes, while the intestinal epithelium requires oxygen for growth and function. Thus, a coculture system that can recreate these contrasting oxygen requirements is critical step towards our understanding microbial-host interactions in the human gut. Here, we demonstrate Intestinal Organoid Physoxic Coculture (IOPC) system, a simple and cost-effective method for coculturing anaerobic intestinal bacteria with human intestinal organoids (HIOs). Using commensal anaerobes with varying degrees of oxygen …

International guidelines designed to minimize the risk of complications that can occur when correcting severe hyponatremia have been widely accepted for a decade. On the basis of the results of a recent large retrospective study of patients hospitalized with hyponatremia, it has been suggested that hyponatremia guidelines have gone too far in limiting the rate of rise of the serum sodium concentration; the need for therapeutic caution and frequent monitoring of the serum sodium concentration has been questioned. These assertions are reminiscent of a controversy that began many years ago. After reviewing the history of that controversy, the evidence supporting …

Systemic sclerosis (SSc), also known as scleroderma, is an autoimmune-driven connective tissue disorder that results in fibrosis of the skin and internal organs such as the lung. Fibroblasts are known as the main effector cells involved in the progression of SSc through the induction of extracellular matrix (ECM) proteins and myofibroblast differentiation. Here, we demonstrate that 4'-(cyclopropylmethyl)-N2-4-pyridinyl-[4,5'-bipyrimidine]-2,2'-diamine (PIK-III), known as class III phosphatidylinositol 3-kinase (PIK3C3/VPS34) inhibitor, exerts potent antifibrotic effects in human dermal fibroblasts (HDFs) by attenuating transforming growth factor-beta 1 (TGF-β1)-induced ECM expression, cell contraction and myofibroblast differentiation. Unexpectedly, neither genetic silencing of PIK3C3 nor other PIK3C3 inhibitors (e.g., …
