Background

Human papillomavirus (HPV) vaccination could prevent cervical and other HPV-associated cancers attributable to vaccine-associated HPV types. However, HPV vaccination coverage among women aged 9–18 years old is low in China. Common barriers include poor financial affordability, minimal public engagement, and low confidence in domestically produced HPV vaccines. Pay-it-forward offers an individual a free or subsidized service then an opportunity to voluntarily donate and/or create a postcard message to support future people. This study aims to assess the effectiveness of pay-it-forward as compared to standard-of-care self-paid vaccination to improve HPV vaccine uptake among adolescent girls aged 15–18 years, who are …

Introduction:

Moderate to severe traumatic brain injury causes significant cognitive impairments, including impairments in social cognition, the ability to recognize others' emotions, and infer others' thoughts. These cognitive impairments can have profound negative effects on communication functions, resulting in a cognitive-communication disorder. Cognitive-communication disorders can significantly limit a person's ability to socialize, work, and study, and thus are critical targets for intervention. This article presents the updated INCOG 2.0 recommendations for management of cognitive-communication disorders. As social cognition is central to cognitive-communication disorders, this update includes interventions for social cognition.

Humans have long been interested in relations among religion/spirituality (R/S), positive psychological constructs, and physical health. Furthermore, many religions attempt to influence behavior through health-related prescriptions about food choices, sexual activity, substance use, and resting. Similarly, positive psychological constructs have been discussed in light of their presumed benefits on both mental and physical health (Ryff & Singer, 1998). However, R/S and positive psychological constructs have only recently become objects of scientific investigation of their associations with physical health.

Prg4/Cd44/Pp2a Signaling Axis: A Significant Regulator Of Gout Arthritis, Sandy Elsayed Jan 2023

Prg4/Cd44/Pp2a Signaling Axis: A Significant Regulator Of Gout Arthritis, Sandy Elsayed

Pharmaceutical Sciences (PhD) Dissertations

Introduction: Gout is a common chronic arthritis caused by monosodium urate (MSU) crystal deposition in joints leading to activation of synovial resident macrophages and downstream production of interleukin-1b (IL-1b). Xanthine oxidase (XO) catalyzes purines into uric acid (UA) and reactive oxygen species (ROS) that activate NLRP3 inflammasome. Protein phosphatase-2A (PP2A) may be involved in regulating inflammatory pathways in macrophages. Proteoglycan 4 (PRG4) and its receptor CD44 and its transducer PP2A signaling axis play a biologically significant role in regulating urate crystal inflammation.


Methods: Monocytes and macrophages were primed with TLR2 agonist and stimulated with MSU crystals. Fingolimod (PP2A …

Influences Of Host Cytokine Signaling On Kshv Infection In Tonsil-Derived B Lymphocytes, Nedaa Alomari

Pharmaceutical Sciences (PhD) Dissertations

Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of kaposi sarcoma. It is also associated with the B cell lymphoproliferative disorders, primary effusion lymphoma (PEL), multicentric Castleman disease (MCD) and KSHV inflammatory cytokine syndrome (KICS). Existing research reveals that KSHV has developed numerous strategies to alter host cytokine signaling activities to facilitate viral persistence and escape host immune surveillance.

Despite three decades of research, there are still many questions in this field awaiting further investigation. This dissertation will investigate host cytokines as factors influencing the establishment of KSHV infection in the human tonsil. We have identified and characterized different cytokines …

Recent developments in neuroscience and artificial intelligence have allowed machines to decode mental processes with growing accuracy. Neuroethicists have speculated that perfecting these technologies may result in reactions ranging from an invasion of privacy to an increase in self-understanding. Yet, evaluating these predictions is difficult given that people are poor at forecasting their reactions. To address this, we developed a paradigm using elements of performance magic to emulate future neurotechnologies. We led 59 participants to believe that a (sham) neurotechnological machine could infer their preferences, detect their errors, and reveal their deep-seated attitudes. The machine gave participants randomly assigned positive …

We set out to determine whether the C-terminus (amino acids 481–798) of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α, UniProt Q9UBK2), a regulatory metabolic protein involved in mitochondrial biogenesis, and respiration, is an arginine methyltransferase substrate. Arginine methylation by protein arginine methyltransferases (PRMTs) alters protein function and thus contributes to various cellular processes. In addition to confirming methylation of the C-terminus by PRMT1 as described in the literature, we have identified methylation by another member of the PRMT family, PRMT7. We performed in vitro methylation reactions using recombinant mammalian PRMT7 and PRMT1 at 37, 30, 21, 18, and 4 °C. …

Communication Sciences and Disorders Faculty Articles and Research

Background

Right hemisphere communication disorders are neither consistently labelled nor adequately defined. Labels associated with right hemisphere brain damage (RHD) are broad and fail to capture the essence of communication challenges needed for stroke-related service provisions. Determination of rehabilitation needs and best-practice guidelines for the education, management and functional improvement of communication disorders after RHD are all predicated on an apt diagnostic label and disorder characteristics.

Aims

In this paper apragmatism is proposed as a potential communication-specific diagnostic label for the impairments in communication that occur after RHD. In particular, the researchers aimed: (1) to establish an operational definition of …

When experiencing dangerous situations, humans have two different responses: fight or flight. During these moments, the sympathetic nervous system takes over and causes the body to work overtime to give the person the best chance at survival. Although the average person doesn’t face a life-or-death experience every day, slips are fairly common and can trigger this fight-or-flight response. Exploring what happens during a slip and quantifying a body’s response can be difficult. Still, with the help of motion capture suits and biometric sensors, there is a unique opportunity to learn more about the kinematics and physiological responses of the human …

Introduction

The response of enterobacteria to oxidative stress is usually considered to be regulated by transcription factors such as OxyR and SoxR. Nevertheless, several reports have shown that under oxidative stress the levels, modification and aminoacylation of tRNAs may be altered suggesting a role of codon bias in regulation of gene expression under this condition.

Methods

In order to characterize the effects of oxidative stress on translation elongation we constructed a library of 61 plasmids, each coding for the green fluorescent protein (GFP) translationally fused to a different set of four identical codons.

Results

Using these reporters, we observed that …

Protein Phosphatase 2a Regulates Xanthine Oxidase-Derived Ros Production In Macrophages And Influx Of Inflammatory Monocytes In A Murine Gout Model, Sandy Elsayed, Khaled A. Elsaid

Pharmacy Faculty Articles and Research

Background: Gout is a common arthritis, due to deposition of monosodium urate (MSU) crystals which results in IL-1β secretion by tissue-resident macrophages. Xanthine oxidase (XO) catalyzes uric acid (UA) production and in the process, reactive oxygen species (ROS) are generated which contributes to NLRP3 inflammasome activation. Protein phosphatase 2A (PP2A) may be involved in regulating inflammatory pathways in macrophages. The objective of this study was to investigate whether PP2A regulates gout inflammation, mediated by XO activity modulation. We studied UA and ROS generations in MSU stimulated murine bone marrow derived macrophages (BMDMs) in response to fingolimod phosphate, a PP2A activator, …
