Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto Feb 2024

Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

Hyperkalemia has been defined as a condition where a serum potassium level is > 5.5 mmol/l. It is associated with fatal dysrhythmias and muscular dysfunction. Certain medical conditions, such as chronic kidney disease (CKD), diabetes mellitus, and others, can lead to hyperkalemia. Many of the signs of hyperkalemia are nonspecific. A history and physical examination can be beneficial in the diagnosis of the condition. In this regard, certain characteristic electrocardiogram findings are associated with hyperkalemia along with laboratory potassium levels. In acute and potentially lethal conditions, hyperkalemia treatments include glucose and insulin, bicarbonate, calcium gluconate, beta-2 agonists, hyperventilation, and dialysis. There …

Pharmacy Faculty Articles and Research

With the first reports on the possibility of genome editing by Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated protein (Cas)9 surfacing in 2005, the enthusiasm for protein silencing via nucleic acid delivery experienced a resurgence following a period of diminished enthusiasm due to challenges in delivering small interfering RNAs (siRNA), especially in vivo. However, delivering the components necessary for this approach into the nucleus is challenging, maybe even more than the cytoplasmic delivery of siRNA. We previously reported the birth of peptide/lipid-associated nucleic acids (PLANAs) for siRNA delivery. This project was designed to investigate the efficiency of …

An average of 60-80% of all menopausal women experience bothersome vasomotor symptoms (VMSs), such as flushing and sweating, within the first seven years of onset. However, despite increasing prevalence, these hot flashes remain hard to treat and have a negative effect on the quality of life. Though hormone replacement therapy is commonly utilized as a standard treatment for VMSs, this therapy is not recommended for all women. Specifically, the oral form of hormone replacement therapy is associated with several contraindications, including a history of thromboembolic disease, migraine headache with aura, liver failure, heart disease, and hormone-dependent cancers. For women with …

Stevens-Johnson syndrome (SJS) is a severe and potentially debilitating skin reaction frequently related to medication use. Allopurinol and angiotensin-converting enzyme (ACE) inhibitors are commonly prescribed medications for prevalent health conditions worldwide, and their interaction associated with SJS warrants further investigation. A comprehensive literature search was performed to investigate cases as studies related to SJS occurring in patients with concomitant use of allopurinol and ACE inhibitors. We identified case reports and studies detailing hypersensitivity reactions, including SJS, attributed to a combination of allopurinol and ACE inhibitors. Despite the drug-drug interactions or lack thereof seen in patient populations, there is no definitive …

Thinking Outside The Box For Experiential Student Learning: Development Of Remote Experiential Learning And Volunteering During The Pandemic, Amy Christopher

Learning Teaching Forum

In response to the COVID-19 pandemic, experiential learning for health care professional programs struggled to find clinical rotation sites and provide students in the didactic curricular phase opportunities to apply health education outside of the classroom. Many healthcare sites and community health screening events were prohibited during an extended period of time due to pandemic isolation. As a health educator, exploration of remote experiential learning took creative planning to ensure students were able to apply their medical knowledge in real-life situations, give back to their community according to Marianist charisms, and fulfill healthcare-related volunteer service hour requirements.

The cellular junctional architecture remodeling by Listeria adhesion protein-heat shock protein 60 (LAP-Hsp60) interaction for Listeria monocytogenes (Lm) passage through the epithelial barrier is incompletely understood. Here, using the gerbil model, permissive to internalin (Inl) A/B-mediated pathways like in humans, we demonstrate that Lm crosses the intestinal villi at 48 h post-infection. In contrast, the single isogenic (lap− or ΔinlA) or double (lap−ΔinlA) mutant strains show significant defects. LAP promotes Lm translocation via endocytosis of cell-cell junctional complex in enterocytes that do not display luminal E-cadherin. In comparison, InlA facilitates …

Auctus: The Journal of Undergraduate Research and Creative Scholarship

Childhood sexual abuse (CSA) is a notable public health concern, affecting a significant proportion of girls in high-income countries. A considerable number of CSA survivors develop Post-Traumatic Stress Disorder (PTSD) by adolescence, which is often considered to be a lifelong disorder with severe emotional and social consequences. Women with CSA-related PTSD display hypervigilance, which is characterized by significantly increased fear network activity and poor top-down control over the amygdala. This meta-analysis examines the potential of intranasal oxytocin (OT) as a treatment for hypervigilance symptoms in women with CSA-related PTSD. The evidence reviewed suggests that intranasal oxytocin can help normalize the …

The Education Prescription: Exploring The Potential Of Patient Education To Reduce Mental Health Issues In Hormonal Contraceptive Users, Maria Abraham

Nursing | Senior Theses

The many birth control options available impact a woman’s life, as hormonal contraceptives are commonly used but often misunderstood. These contraceptives, which contain progestin only, or estrogen and progestin combined, can come in various forms such as pills, implants, IUDs, injections, the vaginal ring, and skin patches. They offer benefits such as reduced menstrual cramps and ectopic pregnancy risk. However, they may lead to adverse side effects which can include increased blood pressure, nausea, headaches, breakthrough bleeding, and a higher risk of blood clots, with research indicating a potential link between oral contraceptive use and a decline in the user’s …

Bioelectrics Publications

Exposure to hydrochloric acid (HCl) can provoke acute and chronic lung injury. Because of its extensive production for industrial use, frequent accidental exposures occur, making HCl one of the top five chemicals causing inhalation injuries. There are no Food and Drug Administration (FDA)-approved treatments for HCl exposure. Heat shock protein 90 (HSP90) inhibitors modulate transforming growth factor-β (TGF-β) signaling and the development of chemical-induced pulmonary fibrosis. However, little is known on the role of Heat Shock Protein 70 (HSP70) during injury and treatment with HSP90 inhibitors. We hypothesized that administration of geranylgeranyl-acetone (GGA), an HSP70 inducer, or gefitinib (GFT), an …

The spore-forming intestinal pathogen Clostridioides difficile causes multidrug resistant infection with a high rate of recurrence after treatment. Piscidins 1 (p1) and 3 (p3), cationic host defense peptides with micromolar cytotoxicity against C. difficile, sensitize C. difficile to clinically relevant antibiotics tested at sublethal concentrations. Both peptides bind to Cu2+ using an amino terminal copper and nickel binding motif. Here, we investigate the two peptides in the apo and holo states as antibiotic adjuvants against an epidemic strain of C. difficile. We find that the presence of the peptides leads to lower doses of …

Immunotherapy for breast cancer is a relatively new treatment option, and research is ongoing to identify the best combination treatments for increasing survival of those diagnosed with TNBC. Eganelisib (IPI-549: a PI3K-gamma inhibitor that works to shift M2 macrophages to M1 to augment T cell function) with other combinatory treatments has shown promising results in reducing tumor growth and increasing survival in mice. …


Quantification Of Antiviral Drug Tenofovir (Tfv) By Surface-Enhanced Raman Spectroscopy (Sers) Using Cumulative Distribution Functions (Cdfs), Marguerite R. Butler, Jana Hrncirova, Meredith Clark, Sucharita Dutta, John B. Cooper Jan 2024

Quantification Of Antiviral Drug Tenofovir (Tfv) By Surface-Enhanced Raman Spectroscopy (Sers) Using Cumulative Distribution Functions (Cdfs), Marguerite R. Butler, Jana Hrncirova, Meredith Clark, Sucharita Dutta, John B. Cooper

Chemistry & Biochemistry Faculty Publications

Surface-enhanced Raman spectroscopy (SERS) is an ultrasensitive spectroscopic technique that generates signal-enhanced fingerprint vibrational spectra of small molecules. However, without rigorous control of SERS substrate active sites, geometry, surface area, or surface functionality, SERS is notoriously irreproducible, complicating the consistent quantitative analysis of small molecules. While evaporatively prepared samples yield significant SERS enhancement resulting in lower detection limits, the distribution of these enhancements along the SERS surface is inherently stochastic. Acquiring spatially resolved SERS spectra of these dried surfaces, we have shown that this enhancement is governed by a power law as a function of analyte concentration. Consequently, by definition, …

The Effects Of Sex Hormones On The Size Of Intestinal Lipoproteins, Andromeda M. Nauli, Ann Phan, Patrick Tso, Surya M. Nauli Dec 2023

The Effects Of Sex Hormones On The Size Of Intestinal Lipoproteins, Andromeda M. Nauli, Ann Phan, Patrick Tso, Surya M. Nauli

Pharmacy Faculty Articles and Research

Larger intestinal lipoproteins are more likely to be retained longer in the intestinal wall, allowing more time for their fat to be hydrolyzed and subsequently taken up by the abdominal viscera. Since men generally accumulate more abdominal visceral fat than women, we sought to determine if males produce larger intestinal lipoproteins compared to females. Using the conscious lymph fistula mouse model, we discovered that the male mice indeed produced larger intestinal lipoproteins than the female mice when they were intraduodenally infused with lipid emulsion. We then employed our differentiated Caco-2 cell model with semipermeable membrane system to determine the effects …

Despite the high mortality rate involved with invasive cerebral mycoses, there is a relative lack of research available around antifungals capable of crossing the blood brain barrier.

In this study the metabolites of four plants (Crocus vernus, Miniature Narcissus (daffodil), Osmanthus delavayi and Taraxacum officinale (common dandelion)) and two bacteria (Lacticaseibacillus paracasei and Staphylococcus epidermidis) were extracted and assayed for antifungal activity against Candida albicans and Saccharomyces cerevisiae. Thin layer chromatography and bioautography were then employed to assess the activity of the constituent components of sources showing antifungal activity.

Metabolites of S.epidermidis, and extracts …

Purpose: To determine perspectives towards opioid use, knowledge on managing an opioid overdose, and awareness towards individuals who use opioids of Indiana physical therapy (PT) professionals. Methods: An online questionnaire was disseminated to PT professionals in Indiana from various practice settings. This questionnaire included two standardized measures, the Opioid Overdose Knowledge Scale (OOKS) and the Opioid Overdose Attitude Scale (OOAS). An additional 12 questions regarding the role of PT and other groups in the opioid crisis as well as opioid education were included. These questions were developed by discussion between investigators as well as feedback from another rehabilitation professional. Descriptive …
