Role Of Gper In Cadmium-Induced Phosphorylation Of Erk1/2 In Ovarian Adenocarcinoma, Laura Sackie

Undergraduate Theses

Cadmium, a carcinogenic heavy metal, is an environmental contaminant found in air, water, and soil. It also exhibits endocrine disruptive properties by mimicking the proliferative effects of the hormone estrogen and is classified as a metalloestrogen. At low concentration levels in some cancer cells, cadmium induces cell proliferation and phosphorylation of ERK1/2, a key protein in the estrogen signaling pathway. While the signaling pathways for cadmium- induced phosphorylation of ERK1/2 have been discovered in breast and lung cancer cells, it has not yet been fully determined in ovarian cancer cells. The fairly recent discovery of a transmembrane receptor found in …

Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas

MSU Graduate Theses

The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …

TCf21 Marks Visceral Adipose Mesenchymal Progenitors And Functions As A Rate-Limiting Factor During Visceral Adipose Tissue Development, Qianglin Liu, Chaoyang Li, Buhao Deng, Peidong Gao, Leshan Wang, Yuxia Li, Mohammad Shiri, Fozi Alkaifi, Junxing Zhao, Jacqueline M. Stephens, Constantine A. Simintiras, Joseph Francis, Jiangwen Sun, Xing Fu

Computer Science Faculty Publications

Distinct locations of different white adipose depots suggest anatomy-specific developmental regulation, a relatively understudied concept. Here, we report a population of Tcf21 lineage cells (Tcf21 LCs) present exclusively in visceral adipose tissue (VAT) that dynamically contributes to VAT development and expansion. During development, the Tcf21 lineage gives rise to adipocytes. In adult mice, Tcf21 LCs transform into a fibrotic or quiescent state. Multiomics analyses show consistent gene expression and chromatin accessibility changes in Tcf21 LC, based on which we constructed a gene-regulatory network governing Tcf21 LC activities. Furthermore, …

Effects Of Storage Conditions On Bpa Leaching From Infant Oral Hygiene Products Using Fluorescence Spectroscopy, Emma Bynum

Honors Theses

Infants are at the highest risk of BPA exposure compared to any other stage of life. Because an infant’s endocrine system is developing, exposure to an endocrine-disruptor, such as BPA, can be especially harmful. Bisphenol-A (BPA) is a structural component in many plastic products, which acts as an endocrine-disruptor mimicking estrogen. This hormonal disruption has been linked to obesity, reproductive issues, cardiovascular problems, and the neurodevelopment disorders. While the FDA monitors things like baby bottles, canned goods, and plastic containers for BPA, infantile oral hygiene products are not closely monitored. Previous research tested infant toothbrushes on the market using a …

Knowledge of Relative Energy Deficiency Among Collegiate Athletes

Low energy availability (LEA) can produce negative health and performance effects for collegiate athletes. It is defined as a deficit between the athlete’s caloric intake and the energy expended during competition or training. The body is then unable to support certain physiological functions that are needed to maintain optimal health. One component of the female athlete triad is disordered eating which can result in low energy availability. Relative Energy Deficiency in Sport is an extension of the female athlete triad, created to take a more holistic approach and include male athletes as …

Inflammatory Bowel Disease Causing Retroperitoneal Varicosity Mimicking A Renal Artery Aneurysm: A Novel Case Report And Literature Review, Areez Shafqat, Shameel Shafqat, Belal Nedal Sabbah, Abdullah Shaik, Wael Khalil Alfehaid, Syed Shafqat Ul Islam

Medical College Documents

A 17-year-old female presented to our hospital complaining of bloody diarrhea 4-6 times per day for the past month. She was a known case of inflammatory bowel disease noncompliant to her medications. Abdominal computed tomography revealed an unusually dilated mass in the retroperitoneum at L2 vertebral level connecting the lumbar and left renal veins. The renal artery was visualized separately, and a diagnosis of communicating vein varicosity was made. This lesion can be misleading on imaging, hence our aim to disseminate our findings to practicing radiologists. The differential diagnosis of these lesions include retroperitoneal lymphadenopathy, renal artery aneurysms, and testicular …

Management Of Adult Growth Hormone Deficiency Related To Hypopituitarism, Kellie Jamin

Capstone Showcase

The treatment of growth hormone deficiency (GHD) is well-established in childhood but less understood in adults, given the more complex role that growth hormone (GH) assumes in this population. Decreased functionality of the pituitary gland, otherwise known as hypopituitarism, can present with an isolated GHD in adulthood, which may result from a number of factors including neoplasm, ischemia, infection, traumatic injury, or systemic disease. Adult GHD may be definitively diagnosed with a stimulation test, the insulin tolerance test (ITT) being the study of choice. With a positive ITT, the disorder can be treated with growth hormone replacement therapy (GHRT), which …

Severe Mixed Mitral Valve Disease Due To Massive Mitral Annular Calcification: A Case Report And Literature Review, Fateh Ali Tipoo Sultan, Sheema Saadia

Section of Cardiology

We present an unusual case of massive mitral annular calcification (MAC) leading to severe mixed mitral valve disease, viz severe mitral regurgitation and severe mitral stenosis. To our knowledge, severe mixed mitral valve disease secondary to MAC is extremely rare. The patient (a 65-year-old lady) presented with worsening shortness of breath and signs of congestive heart failure. Echocardiographic examination revealed massive mitral annular calcification. Despite the massive annular calcification, she had experienced neither embolism nor endocarditis in the past. Because of severe symptomatic mitral regurgitation and mitral stenosis, surgery was advised; however, the patient declined it.

Trends In Stunting, Underweight And Overweight Among Children Aged < 5 Years In Kuwait: Findings From Kuwait Nutritional Surveillance System (2007-2019), Nawal Alqaoud, Abdullah Al-Taiar

Community & Environmental Health Faculty Publications

Background: There is a paucity of data on the secular trends of stunting and overweight among children aged < 5 years in oil-rich countries in the Middle East.

Aims: To examine the secular trends of stunting, underweight and overweight in children aged < 5 years in Kuwait between 2007 and 2019.

Methods: We used large individual data records (n=48 108) from the Kuwait Nutritional Surveillance System (KNSS) to calculate height/length-for-age z score (HAZ), weight-for-age z score and body mass index (BMI)-for-age z score using World Health Organization growth references. Stunting and underweight were defined as less than -2 standard deviation (SD) and overweight (including obesity) as ≥ 2 SD. Trends of stunting, underweight and overweight were …

The Onset Of Exercise-Associated Hyponatremia And Individual Differences In Inappropriate Arginine Vasopressin Excretion: A Review Of Proposed Mechanisms, Michelle Stehman, Stephen A. Maris

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 2: Issue 1, Article 10, 2021. Exercise-associated hyponatremia (EAH) has been reported to develop during endurance events such as triathlons and marathons. As these events become more popular, the incidence of developing EAH also increases. The development of EAH is commonly associated with the overconsumption of hypotonic fluids such as water and tends to be more prevalent in females. There is also evidence to suggest the inappropriate secretion of arginine vasopressin (AVP) leading to water retention may predispose an individual for developing EAH, especially when coupled with the overconsumption of fluids. Recent research …

The Real Hunger Games: Disordered Eating In Male Endurance Athletes And Implications For Bone Health, Sarah Smagacz

Regis University Student Publications (comprehensive collection)

n this thesis, I aim to identify the social factors that cause men with disordered eating and negative body images to be neglected in research, explain a possible mechanism for bone injuries in male endurance athletes, and identify sociocultural factors that could make subpopulations of athletes more susceptible to disordered eating, hormone dysfunction, and bone injuries. The consequences of the physiological dysfunction resulting from disordered eating is not limited to the time in which the individual has disordered eating, but can impact the individual for the rest of their life. I will summarize research about female athletes’ patterns of disordered …

Uplc-Ms/Ms Analysis Of Cyp1a-Mediated Ethoxyresorufin-O-Deethylation Activity In The Rat Kidney Microsomes, Devaraj Venkatapura Chandrashekar, Reza Mehvar

Pharmacy Faculty Articles and Research

Ethoxyresorufin (ER)-O-deethylation (EROD) activity has been widely used to assess cytochrome P450 1A (CYP1A) activity. The kinetics of CYP1A activity have been well characterized in the liver microsomes. However, studies in kidney microsomes are limited due to the much lower EROD activity in this organ. Here, we developed and validated a sensitive UPLC-MS/MS assay for the characterization of the EROD activity in the rat kidney microsomes. In a 50 µL reaction mixture, rat kidney microsomes (0.25 mg/mL) were incubated with ER (0.1–5 µM) and NADPH (1 mM) for 10 min. Acidic solvents, such as trichloroacetic acid or formic …

In the study, the researcher compared 2 groups of type 2 diabetes patients—those who had care coordinator visits from registered nurses and those who did not—through retrospective data collection and analysis from the patients’ electronic medical record from July 2018 through December 2018. An independent samples t test was used to compare the means of the intervention and control groups’ change in HbA1c levels. The intervention and control groups …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey …

Leptin Effects On Bone Metabolism, Elizabeth Bark

Williams Honors College, Honors Research Projects

Scales from adult zebrafish, Danio rerio, are an established model for studying osteoblast and osteoclast activity. In this study, scales in a cell culture were used to determine if the hormone leptin has an effect on activity of these bone remodeling scales. Alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) activities of zebrafish scales were measured and compared with and without leptin treatment. There was no statistically significant difference between leptin treatments in terms of ALP and TRAP activity. Differences between TRAP values between days 1 and 2 did look promising although they were not statistically significant. This study …
