Determining The Ideal Concentrations Of Ethanol And Propylene Glycol In Ethosomes For Transdermal Delivery Of Vitamin D3, Rebecca Conner

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Vitamin D₃ is an important chemical in the human body, however, many Americans have low levels of this vitamin. There are plenty of oral supplementations for Vitamin D₃ deficiency, but those of older age and busy schedules may struggle to meet the minimum requirement. A recently developed ethosomal transmembrane delivery system (Touitou, 2000), similar to liposomes but also containing ethanol, allows users to apply a gel dermally and have the desired drug or active ingredient reach the bloodstream faster. However, there is considerable variation in the concentration of ethanol and permeation enhancers used. Using an affordable method to …

A Case Of Cannabis Smoking Induced Leukocytosis, Ramiro A. Rodriguez Jr., Rukayat Akande, Nevin Varghese

She endorsed heavy marijuana smoking as self-medication and compulsive hot showers for symptom relief. She was admitted for oral intake intolerance, concerning for cannabis hyperemesis syndrome. Her history demonstrated multiple admission for cannabis hyperemesis syndrome during which she demonstrated a leukocytosis which improved with abstinence of marijuana. Her …

Oral Dosages Of The Nsaid Aspirin Decreased The Growth Rate Of Species Found In The Human Gut Microbiome Including Akkermansia Muciniphila, Bacteroides Fragilis, Clostridium Sordellii, And Clostridium Difficile, Wyatt H. Greenbaum, Garrett J. Greenbaum, Anna Spiezio

PANDION: The Osprey Journal of Research and Ideas

Over past few decades, new insight has been revealed in the scientific community about the importance of the human gut microbiome relating to general health. It is known that imbalances in the species that reside in the human gut can cause organism-wide problems in humans. When prescribing or injecting oral medications, the thought of the downstream effects on the gut microbiome are not always considered. By exposing known healthy members of the gut; Akkermansia muciniphila, Bacteroides fragilis, Clostridium sordellii, and Clostridium difficile to the Aspirin, this study attempted to provide insight into the effects of the drug on bacterial growth. …

All-Cause And Opioid-Related Mortality Compared Between Traumatic Spinal Cord Injury And The Us General Population, Jaden Whitehead, Beatrice Ugiliweneza

The Cardinal Edge

Individuals with spinal cord injury (SCI) are susceptible to the misuse of opioids due to the introduction of these substances for pain management. There are very few studies examining the relationship between unintentional deaths caused by opioid usage following spinal cord injury. The objective of this study was to evaluate the trend of opioid-related mortality of individuals with spinal cord injury (SCI) over the years and compare these findings to the mortality rates due to opioid misuse in the general population. In this study, we used data provided by the National Spinal Cord Injury Model Systems (NSCIMS) for SCI 1999-2016 …

Sex Differences In Mood And Anxiety-Related Outcomes In Response To Adolescent Nicotine Exposure, Tsun Hay Jason Ng

Electronic Thesis and Dissertation Repository

Nicotine dependence is causally linked to increased risk of mood/anxiety disorders in later life. Females are reported to experience a higher prevalence of anxiety/depressive disorders and challenges in smoking cessation therapies, suggesting a potential sex-specific response to nicotine exposure and mood/anxiety disorder risk. However, pre-clinical evidence of sex-specific responses to adolescent nicotine exposure is unclear. Thus, to determine any sex differences in anxiety/depressive-related outcomes, adolescent male and female Sprague Dawley rats received nicotine (0.4 mg/kg; 3x daily) or saline injections for 10 consecutive days, followed by behavioural testing, in-vivo electrophysiology and Western Blot analyses. Our results revealed that adolescent nicotine …

Α7 Nicotinic Acetylcholine Receptor Interaction With G Proteins In Breast Cancer Cell Proliferation, Motility, And Calcium Signaling, Murat Oz, Justin R. King, Keun-Hang Susan Yang, Sarah Khushaish, Yulia Tchugunova, Maitham A. Khajah, Yunus A. Luqmani, Nadine Kabbani

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Chronic smoking is a primary risk factor for breast cancer due to the presence of various toxins and carcinogens within tobacco products. Nicotine is the primary addictive component of tobacco products and has been shown to promote breast cancer cell proliferation and metastases. Nicotine activates nicotinic acetylcholine receptors (nAChRs) that are expressed in cancer cell lines. Here, we examine the role of the α7 nAChR in coupling to heterotrimeric G proteins within breast cancer MCF-7 cells. Pharmacological activation of the α7 nAChR using choline or nicotine was found to increase proliferation, motility, and calcium signaling in MCF-7 cells. This effect …

Evidence supports unequal burdens of chemical exposures from personal care products (PCPs) among some groups, namely femme-identifying and racial and ethnic minorities. In this study, we implemented an online questionnaire to assess PCP purchasing and usage behaviors and perceptions of use among a sample of US adults recruited at a Northeastern university. We collected PCP use across seven product categories (hair, beauty, skincare, perfumes/colognes, feminine hygiene, oral care, other), and behaviors, attitudes, and perceptions of use and safety across sociodemographic factors to evaluate relationships between sociodemographic factors and the total number of products used within the prior 24–48 h using …

Calcium Carbonate As A Potential Intervention To Prevent Labor Dystocia: Narrative Review Of The Literature, Sabahat Raees, Marie Forgie, Rita Mitchell, Emily Malloy

Journal of Patient-Centered Research and Reviews

Anecdotally, there are attestations from clinicians of calcium carbonate being used successfully for laboring people experiencing labor dystocia. The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in obstetrics to explore the potential benefit of calcium carbonate as a simple and low-cost intervention for prevention or treatment of labor dystocia. To answer how calcium and carbonate physiologically contribute to myometrium contractility, we conducted a literature search of English-language peer-reviewed articles, with no year limitation, consisting of the keywords “calcium,” “calcium carbonate,” “calcium gluconate,” “pregnancy,” “hemorrhage,” and variations of “smooth muscle contractility” and …

Parabens Promote Protumorigenic Effects In Luminal Breast Cancer Cell Lines With Diverse Genetic Ancestry, Jazma L. Tapia, Jillian C. Mcdonough, Emily L. Cauble, Cesar G. Gonzalez, Dede K. Teteh, Lindsey S. Treviño

Health Sciences and Kinesiology Faculty Articles

Context

One in 8 women will develop breast cancer in their lifetime. Yet, the burden of disease is greater in Black women. Black women have a 40% higher mortality rate than White women, and a higher incidence of breast cancer at age 40 and younger. While the underlying cause of this disparity is multifactorial, exposure to endocrine disrupting chemicals (EDCs) in hair and other personal care products has been associated with an increased risk of breast cancer. Parabens are known EDCs that are commonly used as preservatives in hair and other personal care products, and Black women are disproportionately exposed …

Death After Marijuana Use In A 27-Year-Old Male: A Case Report, Samantha M. Lavertue*, Sadie Signorella*, Rohail Baig, Amarah Emerson, John Joyce, Roland Zhang

Advances in Clinical Medical Research and Healthcare Delivery

The dangers of marijuana use are well documented across most body systems. We report a 27-year-old male who ingested marijuana and then experienced an ST-elevation myocardial infarction, subsequent cerebrovascular accident, and death within the span of a week. Toxicology reports were positive for THC only, echocardiography revealed diffuse hypokinesis with an ejection fraction estimated at 15-20%, and troponins peaked at greater than 270,000 pg/mL. Due to decreased Glasgow Coma Score and hemodynamic instability, the patient was not taken for cardiac catheterization, but was subsequently sedated, intubated, and placed on pressor support in the ICU. Initial brain imaging was negative for …

Development Of Rp-Hplc Method For Simultaneous Determination Of Nebivolol Hydrochloride, Valsartan And Hydrochlorothiazide In Co-Administrated Antihypertensive Agents And Human Plasma, Shereen Mowaka, M. Rizk, Maha M. Abou El‐Alamin, Mariam Mohamed

Pharmacy

Reversed phase high performance liquid chromatography combined with photodiode array (HPLC-PDA) detector method was developed for simultaneous determination of two binary antihypertensive combinations; either Nebivolol (NEB) with Hydrochlorothiazide (HCZ) or with Valsartan (VAL) in pharmaceutical formulation and spiked human plasma. The method was successfully applied to separate the three drugs on one chromatogram under the same chromatographic conditions that used for two binary combinations. The separation was established on Xterra C18 column using gradient mobile phase which composed of acidified water of pH = 3.0 (adjusted with 0.1% orthophosphoric acid) and acetonitrile with flow rate of 1.0 mL/min. The drugs …

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Release The Kratom: Post-Acute Withdrawal Syndrome In A 70 Year Old Male, Nardin El-Shammaa, Kyle Street, Narshima Pinninti

Stratford Campus Research Day

Centuries in Eastern medicine.. Kratom has been commonly used for chronic pain and opiate withdrawal symptoms with first reported cases in the United States in the early 2000s. It is a plant that consists of psychoactive alkaloids that target opioid receptors with different affinity. Effects from Kratom are dose-dependent, at lower doses, it acts as a stimulant, while at higher doses produces analgesia and euphoria. Although Kratom is legal and easily accessible over the counter, there have been increasing reports of potential for addiction and toxicity. Cessation of Kratom can result in withdrawal symptoms similar to opiate withdrawal. Here we …

Photodynamic Therapy Agents: The Power Of Mjöllnir To Eradicate Cancer, Sidney M. Hopper

Honors College Theses

After its discovery back in the 1900s, photosensitizers became a critical study for potential treatments and cures for medical issues, including cancer. It was discovered that porphyrins appeared to target and accumulate in proliferating cells, and to reach the cells, a certain wavelength of light with maximum absorbance associated with the porphyrin was necessary to achieve cell death. Photodynamic therapy involves making use of porphyrins or metalloporphyrins as activators when exposed to such light. When activated, these compounds generate reactive oxygen species (ROS), such as HO- or O2-, which can react with nucleic acids found in DNA and RNA. In …

Assessing Knowledge, Attitude, And Practice Among College Students Regarding Second-Hand And Third-Hand Smoke, Laura Y. Rebolledo

Electronic Theses, Projects, and Dissertations

Background: The tobacco epidemic has been a constant since the popularization of tobacco products. However, with the introduction of non-combustible products that include e-cigarettes and vapes, the usage of tobacco products has continued to increase. Tobacco exposure can stem from first-hand (FHS), second-hand (SHS), and third-hand smoke (THS), with the last two impacting even non-smokers. The health effects from all types of tobacco exposure can be detrimental. These effects include the risk of cancer in any organ of the body, cardiovascular disease, and respiratory diseases.

Methods: The study utilized a cross-sectional design through an anonymous web-based survey given …

Apoptosis Induction In Jurkat T-Lymphocytes By Proton Pump Inhibitors (Ppis), Shreya Murali, Randall Reif

Student Research Submissions

Apoptosis, commonly known as programmed cell death, constantly occurs in humans. As a cancer cell increases in acidity, apoptosis is induced. In healthy cells, proton pump proteins allow for H⁺ ions to permeate cellular membranes, regulating pH. However, proton pump inhibitors (PPIs), such as omeprazole, prevent proton movement. In previous studies, omeprazole induced cell death in Jurkat T lymphocytes; however, there was no confirmation of whether the cells died through apoptosis, or through necrosis, where the cell bursts. By using Annexin-V staining, the effects of omeprazole, dexlansoprazole, and esomeprazole on apoptosis induction can be measured. Cell death was observed …

Chewed Versus Swallowed Ticagrelor In P2y12 Inhibitor-Naïve Patients Undergoing Percutaneous Coronary Intervention, Thomas F. Wilson, Muddasir Ashraf, M. Fuad Jan, Tonga Nfor, Louie Kostopoulos, Joaquin Solis, Jayant Khitha, Ahmad Khraisat, Anthony C. Defranco, Tanvir Bajwa, Suhail Q. Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose: Dual antiplatelet therapy is standard for patients undergoing percutaneous coronary intervention (PCI) with stents. Traditionally, patients swallow the loading dose of a P2Y12 inhibitor before or during PCI. Time to achieve adequate platelet inhibition after swallowing the loading dose varies significantly. Chewed tablets may allow more rapid inhibition of platelet aggregation. However, data for this strategy in patients with stable ischemic heart disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) are less robust.

Methods: In this single-center prospective trial, 112 P2Y12-naïve patients with stable ischemic heart disease or NSTE-ACS on aspirin therapy and who received ticagrelor after coronary angiography but …
