Protein S In Coagulation And Inflammation, Martha Mega Silvia Sim
Protein S In Coagulation And Inflammation, Martha Mega Silvia Sim
Theses and Dissertations--Molecular and Cellular Biochemistry
Protein S (PS) is a key regulator, which links inflammation and coagulation and performs multiple proposed functions in both processes. PS exists in the blood as a free soluble form (~40%), bound to complement component 4b-binding protein/ C4BP (~60%), and packaged in platelet α-granules (~2.5%). Subendothelial tissue factor (TF), upon exposure to blood, initiates coagulation, a proteolytic cascade which results in the activation of thrombin, the enzyme responsible for formation of a fibrin clot. PS is a critical anticoagulant that inhibits multiple steps of this process. Only the free fraction of PS has full anticoagulant properties, as C4BP blocks this …

Replication of porcine circovirus type 2 (PCV2), an important worldwide swine pathogen, has been demonstrated to be influenced by host genotype. Specifically, a missense DNA polymorphism (SYNGR2 p.Arg63Cys) within the SYNGR2 gene was demonstrated to contribute to variation in PCV2b viral load and subsequent immune response following infection. PCV2 is known to induce immunosuppression leading to an increase in susceptibility to subsequent infections with other viral pathogens such as porcine reproductive and respiratory syndrome virus (PRRSV). In order to assess the role of SYNGR2 p.Arg63Cys in co-infections, pigs homozygous for the favorable SYNGR2 p.63Cys (N = 30) …
The Effect Of An Educational Handout On Knowledge, Awareness And Attitudes Of Pre-Exposure Prophylaxis (Prep) Among Participants At A Needle And Syringe Exchange Site, Mckenzie Buckel
DNP Projects
Background: In 2018, the total number of HIV cases in the United States was 1.2 million. Almost 186,500 of these cases were attributed to intravenous drug use. With the adherence to pre-exposure prophylaxis (PrEP) there is approximately a 49% decrease in the rates of HIV among people who inject drugs and the most significant barrier to PrEP among this population is a lack of awareness and knowledge.
Objective: The purpose of this study was to determine participants’ of a needle and syringe exchange site knowledge, awareness and attitudes of PrEP after reviewing an educational handout about PrEP.
Methods: A quasi …

Introduction: Among US men, oropharyngeal cancer (cancer of the back of the mouth and throat) is the 8th most common cancer. If detected early, human papillomavirus (HPV)-16-associated oropharyngeal cancer has a high 5-year survival rate. Risk factors such as high numbers of oral sex partners, disparities in smoking and drinking, and low rates of HPV vaccination may put gay and bisexual men at even higher risk for oropharyngeal cancer.
Methods: We recruited 21 healthcare providers in Minneapolis-St. Paul, Minnesota and Houston, Texas to participate in semi-structured interviews. Nurses, physician assistants, dental hygienists, and dentists were asked about their clinical experiences …

The present study aimed at identifying risk factors associated with periodontitis development and periodontal health disparities with emphasis on differential oral microbiota. The prevalence of periodontitis is recently rising dentate adults in the US, which presents a challenge to oral health and overall health. The risk of developing periodontitis is higher in African Americans (AAs), and Hispanic Americans (HAs) than in Caucasian Americans (CAs). To identify potentially microbiological determinations of periodontal health disparities, we examined the distribution of several potentially beneficial and pathogenic bacteria in the oral cavities of AA, CA, and HA study participants. Dental plaque samples from 340 …
Induction Of Antibiotic Activity Against Methicillin-Resistant Staphylococcus Aureus In Small Molecules Through Zinc Activation, Rachel Michaela Andrews
Induction Of Antibiotic Activity Against Methicillin-Resistant Staphylococcus Aureus In Small Molecules Through Zinc Activation, Rachel Michaela Andrews
All ETDs from UAB
Methicillin-resistant Staphylococcus aureus (MRSA) is a serious human pathogen with a staggering potential for multi-drug resistance. Because of this, the Centers for Disease Control and Prevention and the World Health Organization monitor the spread of MRSA and encourage antibiotic development efforts targeting this pathogen. Despite this, few antibiotics have been developed and brought to market in recent decades. To continue treating infections caused by this organism, we must identify novel antibiotic molecules with different mechanisms of action from known antibiotics. Bacterial copper-dependent inhibitors (CDIs), molecules that become antibacterial in the presence of copper (Cu), have been studied as a novel …
Transmission Competence Of B. Burgdorferi Infected Ixodes Ticks And Development Of An Ospc-Based Lyme Disease Vaccine, Samanta Kamalika
Transmission Competence Of B. Burgdorferi Infected Ixodes Ticks And Development Of An Ospc-Based Lyme Disease Vaccine, Samanta Kamalika
Theses and Dissertations (ETD)
Introduction. Lyme disease, otherwise called Lyme borreliosis, is a vector-borne infectious disease caused by the spirochete Borrelia burgdorferi (Bb). Studying the increase in overall Lyme disease incidence requires understanding the role of the vector Ixodes scapularis (I. scapularis) as the agent that carries the spirochete which is important to limit the occurrence of Lyme disease. Once we understand the vector-pathogen response, it also becomes important to determine the remedies for Lyme disease. Lyme disease can be treated with antibiotics if detected early, but the major obstacle lies in the early detection process. Therefore, it is important to investigate alternative preventive …

Theses and Dissertations (ETD)
Despite being an ancient disease caused by Mycobacterium tuberculosis (Mtb) and after decades of research, tuberculosis (TB) still affects millions of people every year worldwide. In 2018, the World Health Organization (WHO) reported that 10 million people developed tuberculosis and 1.5 million died of the disease. With the increase in the multidrug-resistant (MDR) and extensively drug-resistant (XDR) cases, the treatment for TB with the standard first and second-line therapy is becoming increasingly difficult. Therefore, there is an urgent need to find new anti-TB drugs as combination partners of existing and experimental classes of antimicrobial agents to shorten and simplify the …
Regulatory Elements Of Polyphosphate Biosynthesis, Marvin Qortez Bowlin
Regulatory Elements Of Polyphosphate Biosynthesis, Marvin Qortez Bowlin
All ETDs from UAB
Polyphosphate (polyP) is an ancient, conserved, inorganic biomolecule. Biological systems have adapted many functions for this high-energy molecule, ranging from immune regulation in mammals to gene regulation in prokaryotes. Of particular interest is its use in bacterial stress responses. Bacteria use polyP to resist hazardous environmental elements like toxic molecules or nutrient starvation. In many bacterial species, polyP is synthesized by polyphosphate kinases (PPKs). PPK – discovered in Escherica coli (E. coli) – hydrolyzes adenosine-5’-triphosphate (ATP) to synthesize polyP. Species that use PPK develop multiple pathogenic defects when PPK activity is impaired, including, among others, antibiotic susceptibility. There is no …

All ETDs from UAB
Lower respiratory infections are the primary cause of infectious death among the elderly. One reason for this is ‘inflamm-aging,’ a chronic low-grade inflammatory state that develops with advanced age. Pertinently, our group has shown increases in TNF levels to be responsible for age-dependent macrophage dysfunction (ADMD) and, in turn, enhanced susceptibility to Streptococcus pneumoniae, the leading cause of community-acquired pneumonia. The underlying molecular mechanisms responsible, however, remain unclear. Following adoptive transfer of alveolar macrophages (AM) from aged (18+ months) or young (3-6 month) mice into young mice, followed by infection with S. pneumoniae, we found that aged AM were sufficient …

Ethanol Decreases Expression Of Developing Neurons, But Not Neuronal Viability, In A Cultured Rat Hippocampus, Cassidy Count
Theses and Dissertations--Psychology
As of 2019, alcohol use disorders (AUDs) affect roughly 14.1 million individuals over the age of 18 and cost up to $249 billion in economic burden in the United States. In addition to central nervous system (CNS), those affected by AUDs can present with cognitive and behavioral abnormalities. Specifically, those affected by AUDs experience deficits in memory consolidation and retrieval as well as executive functioning, which may be due to cellular changes within the hippocampus. There are at least two prominent and contended theories which explain the mechanism of functional impairment caused by alcohol: 1) alcohol induces excitotoxic neuronal death …

Development Of A Pseudotype-Based Neutralization Test For Sars-Cov-2 Antibody Measurement, Kunlanan Charsangbong
Chulalongkorn University Theses and Dissertations (Chula ETD)
The gold standard for measuring anti-SARS-CoV-2 neutralizing antibody is a live-virus neutralization test (VNT). However, VNT is rather complex and must be performed in a biosafety level 3 facility. Therefore, a gene-encoding spike protein of the original SARS-CoV-2 variant was designed to develop a lentivirus-based SARS-CoV-2 pseudotype in this study to replace the live virus, which can be conducted in a biosafety level 2 facility. The 2nd generation lentiviral pseudotype with green fluorescent protein (GFP) and the 3rd generation lentiviral pseudotype with luciferase as a reporter system, respectively, provided a sufficient titer (TCID50/mL) for a neutralization test. However, the 3rd …

Chulalongkorn University Theses and Dissertations (Chula ETD)
Mycobacterium species cause several vital human diseases, including tuberculosis (TB) and non-tuberculous mycobacterial (NTM) infections. TB is a chronic infectious disease caused by the Mycobacterium tuberculosis complex (MTBC). Additionally, non-tuberculous mycobacteria infections are caused by major NTM species, including Mycobacterium abscessus, Mycobacterium avium, Mycobacterium fortuitum, Mycobacterium kansasii, Mycobacterium gordonae, and Mycobacterium intracelulare, are medically necessary. Both groups of infections can lead to outbreaks in immunocompromised individuals and AIDS patients. It is crucial to differentiate between these two groups of mycobacterial infections, as they require distinct treatment approaches. However, initial diagnosis poses limitations in terms of time and diagnostic tools. Therefore, …

The Diagnostic Value Of Bispectral Index For Assessing Sleep Quality After Elective Surgery In Intensive Care Unit, Pongpol Sirilaksanamanon
Chulalongkorn University Theses and Dissertations (Chula ETD)
Sleep abnormality is common in the intensive care unit (ICU). Monitoring and improving sleep quality may help recovery and improve outcomes from a major illness. Although polysomnography is a gold standard for measuring sleep quality, routine use is impractical due to cost and complexity. This study aimed to investigate the diagnostic accuracy of an alternative monitor, the Bispectral Index (BIS), compared to polysomnography for evaluating the quality of postoperative sleep in the ICU. This was a prospective observational study. Enrolled patients were monitored with both BIS and polysomnography during the first night after surgery. Results: Thirty-three patients were enrolled. The …
Immunogenicity And Safety Of The Third Booster Dose With Homologous Or Heterologous Covid-19 Vaccine After Completing Primary Series Of Inactivated Vaccine (Coronavac) Or Adenovirus Vector Vaccine (Azd1222) In Thai Adults, Suvichada Assawakosri
Chulalongkorn University Theses and Dissertations (Chula ETD)
COVID-19 has spread across 200 countries, causing 705 million confirmed cases and 7 million deaths. Several vaccines have been approved by the World Health Organization to prevent the spread of the virus. The Omicron variant has become the predominant strain globally. Although most people have been vaccinated, primary doses of CoronaVac or AZD1222 may not provide adequate protection against the Omicron variants. Studies show that vaccine-induced immunity has declined over time, leading to increase of breakthrough infection cases. A heterologous booster administered after primary vaccination, is hypothesized to enhance the immune response against the newly emerged SARS-CoV-2 variant. This study …

Bacterial meningitis differs globally, and the incidence and case fatality rates vary by region, country, pathogen, and age group; being a life-threatening disease with a high case fatality rate and long-term complications in low-income countries. Africa has the most significant prevalence of bacterial meningitis illness, and the outbreaks typically vary with the season and the geographic location, with a high incidence in the meningitis belt of the sub-Saharan area from Senegal to Ethiopia. Streptococcus pneumoniae (pneumococcus) and Neisseria meningitidis (meningococcus) are the main etiological agents of bacterial meningitis in adults and children above the age of one. Streptococcus agalactiae (group …

There is a possible accelerated biological aging in patients with substance use disorders (SUD). The evaluation of epigenetic clocks, which are accurate estimators of biological aging based on DNA methylation changes, has been limited to blood tissue in patients with SUD. Consequently, the impact of biological aging in the brain of individuals with SUD remains unknown. In this study, we evaluated multiple epigenetic clocks (DNAmAge, DNAmAgeHannum, DNAmAgeSkinBlood, DNAmPhenoAge, DNAmGrimAge, and DNAmTL) in individuals with SUD (n = 42), including alcohol (n = 10), opioid (n = 19), and stimulant use disorder (n = 13), and controls (n = 10) in …

The lymphatics play important roles in chronic diseases/conditions that comprise the bulk of healthcare worldwide. Yet the ability to routinely image and diagnose lymphatic dysfunction, using commonly available clinical imaging modalities, has been lacking and as a result, the development of effective treatment strategies suffers. Nearly two decades ago, investigational near-infrared fluorescence lymphatic imaging and ICG lymphography were developed as routine diagnostic for clinically evaluating, quantifying, and treating lymphatic dysfunction in cancer-related and primary lymphedema, chronic venous disease, and more recently, autoimmune and neurodegenerative disorders. In this review, we provide an overview of what these non-invasive technologies have taught us …

Pharmacogenomics (PGx) is considered an emergent field in developing countries. Research on PGx in the Latin American and the Caribbean (LAC) region remains scarce, with limited information in some populations. Thus, extrapolations are complicated, especially in mixed populations. In this paper, we reviewed and analyzed pharmacogenomic knowledge among the LAC scientific and clinical community and examined barriers to clinical application. We performed a search for publications and clinical trials in the field worldwide and evaluated the contribution of LAC. Next, we conducted a regional structured survey that evaluated a list of 14 potential barriers to the clinical implementation of biomarkers …
