How Users' Perceptions Of Friends' Content Influence Their "Annoyance" After Viewing Facebook Posts, Mai-Ly N Steers, Robert E Wickham, Olivia M Tabaczyk, Chelsie M Young, Michelle C Quist, Lindsey B Eikenburg, Jennifer L Bryan

Faculty, Staff and Students Publications

Social media posts may elicit strong, instantaneous feelings of irritation, or "annoyance." The current experiment investigated how participants' ratings of Facebook posts and their levels of closeness to the poster impacted these feelings. Respondents (N = 476) were asked to rate how irrelevant, inappropriate, mundane, and annoying Facebook posts from an imagined close friend, moderately close friend, and acquaintance were. A cross-classified, Bayesian structural equation model determined the unique contributions at the rater level, target level, and the distinct combination of rater and target at the within level. At the within level, results suggested irrelevance, mundaneness, and inappropriateness of posts …

Faculty, Staff and Students Publications

BACKGROUND: Testosterone (T) therapy increases lean mass and reduces total body and truncal fat mass in hypogonadal men. However, the underlying molecular mechanisms for the reciprocal changes in fat and lean mass in humans are not entirely clear.

METHODS: Secondary analysis of specimens obtained from a single-arm, open-label clinical trial on pharmacogenetics of response to T therapy in men with late-onset hypogonadism, conducted between 2011 and 2016 involving 105 men (40-74 years old), who were given intramuscular T cypionate 200 mg every 2 weeks for 18 months. Subcutaneous fat (SCF), peripheral blood mononuclear cells (PBMC) and serum were obtained from …

Steroid Receptor Coactivators In Treg And Th17 Cell Biology And Function, Yosi Gilad, Ortal Shimon, Sang Jun Han, David M Lonard, Bert W O'Malley

Faculty, Staff and Students Publications

Steroid receptor coactivators (SRCs) are master regulators of transcription that play key roles in human physiology and pathology. SRCs are particularly important for the regulation of the immune system with major roles in lymphocyte fate determination and function, macrophage activity, regulation of nuclear factor κB (NF-κB) transcriptional activity and other immune system biology. The three members of the p160 SRC family comprise a network of immune-regulatory proteins that can function independently or act in synergy with each other, and compensate for - or moderate - the activity of other SRCs. Recent evidence indicates that the SRCs are key participants in …

Self-Rectifying Magnetoelectric Metamaterials For Remote Neural Stimulation And Motor Function Restoration, Joshua C Chen, Gauri Bhave, Fatima Alrashdan, Abdeali Dhuliyawalla, Katie J Hogan, Antonios G Mikos, Jacob T Robinson

Faculty, Staff and Students Publications

Magnetoelectric materials convert magnetic fields into electric fields. These materials are often used in wireless electronic and biomedical applications. For example, magnetoelectrics could enable the remote stimulation of neural tissue, but the optimal resonance frequencies are typically too high to stimulate neural activity. Here we describe a self-rectifying magnetoelectric metamaterial for a precisely timed neural stimulation. This metamaterial relies on nonlinear charge transport across semiconductor layers that allow the material to generate a steady bias voltage in the presence of an alternating magnetic field. We generate arbitrary pulse sequences with time-averaged voltage biases in excess of 2 V. As a …

Faculty, Staff and Students Publications

Background: Idiopathic pulmonary fibrosis (IPF) is the result of multiple cycles of epithelial cell injury and fibroblast activation; currently, there is no clear etiology. Increasing evidence suggests that protein metabolism and amino acids play a crucial role in IPF, but the role of D-amino acids is not yet clear. The aim of this study was to identify novel mediators in order to test the hypothesis that D-amino acid oxidase (DAO) plays a significant role in the pathogenesis of IPF.

Methods: We analyzed DAO gene expression in patients with IPF and mice with bleomycin (BLM)-induced lung fibrosis. We performed in vitro …

Maladaptive Behaviors In Disasters: Case Study Evaluation Of Hurricane Hugo, Hurricane Katrina And The Haiti Earthquake, Andrew M Milsten, Christopher S Kang, Ira Nemeth

Faculty, Staff and Students Publications

Maladaptive behaviors during a disaster refer to actions that do not benefit the individual or society. Quarantelli highlights several maladaptive behaviors myths associated with disasters: widespread antisocial behavior, passivity, role conflict or abandonment, and sudden widespread mental health breakdowns (1). Despite early work reporting these myths, the common perception is that maladaptive behaviors such as rioting, looting, panic, and criminal conduct are prevalent in the wake of disasters. This is despite research by de Ville de Goyet and Arnold which has called on public officials and the media to stop propagating false disaster myths (2, 3). The classic academic response …

Faculty, Staff and Students Publications

Patients with reflux-like symptoms (heartburn and regurgitation) are often not well advised on implementing individualised strategies to help control their symptoms using dietary changes, lifestyle modifications, behavioural changes or fast-acting rescue therapies. One reason for this may be the lack of emphasis in management guidelines owing to 'low-quality' evidence and a paucity of interventional studies. Thus, a panel of 11 gastroenterologists and primary care doctors used the Delphi method to develop consolidated advice for patients based on expert consensus. A steering committee selected topics for literature searches using the PubMed database, and a modified Delphi process including two online meetings …

School of Medicine Publications

The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) has categorized psychosis disorders (Schizophrenia, Schizoaffective Disorder and Bipolar Disorder) into three distinct Biotypes, based on neurobiological measurements in a multi-ancestry sample. Two recently developed post hoc ancestry adjustment methods of Polygenic Risk Scores (PRSs) generate Trans-Ancestry PRSs (TAPRSs), which allow for PRS analysis of multi-ancestry samples. Applied to schizophrenia PRS, we found the Khera TAPRS method to show superior portability and comparable prediction accuracy as compared with the Ge method. The three Biotypes of psychosis disorders had similar TAPRSs across ancestries. In genomic analysis of Biotypes, nine genes and isoforms showed significant …

Faculty, Staff and Students Publications

Type 2 diabetes (T2D) is a common forerunner of neurodegeneration and accompanying dementia, including Alzheimer's Disease (AD), yet the mechanisms underlying this comorbidity remain unresolved. Individuals of Mexican descent living in South Texas have increased prevalence of comorbid T2D and early onset AD, despite low incidence of the APOE-ε4 risk variant among the population and an absence of a similar predisposition among relatives residing in Mexico - suggesting a role for environmental factors in coincident T2D and AD susceptibility. We therefore sought to test if differences in gut community structure could be observed in this population prior to any AD …

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife diseases have implications for ecology, conservation, human health, and health of domestic animals. They may impact wildlife health and population dynamics. Exposure rates of coyotes (Canis latrans) to pathogens such as Yersinia pestis, the cause of plague, may reflect prevalence rates in both rodent prey and human populations. We captured coyotes in north-central New Mexico during 2005–2008 and collected blood samples for serologic surveys. We tested for antibodies against canine distemper virus (CDV, Canine morbillivirus), canine parvovirus (CPV, Carnivore protoparvovirus), plague, tularemia (Francisella tularensis), and for canine heartworm (Dirofilaria immitis) antigen.

United States Department of Agriculture Wildlife Services: Staff Publications

African swine fever (ASF) causes significant morbidity and mortality in both domestic and wild suids (Sus scrofa), and disease outbreaks convey profound economic costs to impacted industries due to death loss, the cost of culling exposed/infected animals as the primary disease control measure, and trade restrictions. The co-occurrence of domestic and wild suids significantly complicates ASF management given the potential for wild populations to serve as persistent sources for spillover. We describe the unique threat of African swine fever virus (ASFV) introduction to the United States from epidemiological and ecological perspectives with a specific focus on disease management at the …

Overview Of Global Wildlife–Livestock Interfaces: The Array Of Conflicts And Strategies To Mitigate Them, Kurt C. Vercauteren, Stewart Breck

United States Department of Agriculture Wildlife Services: Staff Publications

Implications

Wildlife–livestock conflict can be broadly categorized as either competition for resources, disease transmission between wildlife and domestic species, or predation.
Management strategies can either focus on management of the livestock or management of the wildlife. Dynamic integration of both these strategies likely provides the best solution in many scenarios.
Reducing conflict and maintaining ecologically appropriate and viable populations of wildlife and thriving human endeavors should be the ultimate goal.

Use Of Rhodamine B As A Biomarker In A Simulated Oral Vaccine Deployment Against Bovine Tuberculosis In White-Tailed Deer, David Dressel, Kurt Vercauteren, Michael Lavelle, Nathan P. Snow, Henry Campa Iii

United States Department of Agriculture Wildlife Services: Staff Publications

Introduction Free-ranging white-tailed deer (Odocoileus virginianus) in northeastern lower Michigan, United States are a self-sustaining reservoir for bovine tuberculosis (bTB). Farm mitigation practices, baiting bans, and antlerless deer harvests have been ineffective in eliminating bTB in white-tailed deer and risks to cattle. The apparent prevalence has remained relatively constant in deer, prompting interest among wildlife researchers, managers, and veterinarians for an effective means of vaccinating deer against bTB. The commonly used human vaccine for bTB, Bacillus Calmette Guerin (BCG), is the primary candidate with oral delivery being the logical means for vaccinating deer.
