Impact Of Tetrahydrocannabinol (Thc) On Daphnia Magna Heart Rate, Ashley Cosgrave

Williams Honors College, Honors Research Projects

Marijuana (Cannabis) is currently federally illegal within the United States and classified as a Schedule I drug. This leaves a large research gap on the impacts of Tetrahydrocannabinol (THC) use. Daphnia magna are frequently used as a model organism for the human heart and toxicology screenings due to their myogenic heart, similarities in physiological pathways, and sensitivity to toxins. As such, in order to bridge the research gap and uncover potential use of Daphnia magna as a model organism for humans in regard to impact on heart rate, we hypothesized that if Daphnia magna possess CB1 receptors or an equivalent …

Investigating The Impact Of Chronic Inflammatory Pain On Ethanol Consumption In Mouse Models., Joshua L. Hunt

Theses and Dissertations

Chronic pain affects nearly 20% of Americans annually and for many alcohol provides a convenient and legally acquired palliative. Population-based studies have suggested a link between increased alcohol use and reduced pain, but chronic or excessive alcohol use potentiates the risk to develop alcohol dependence and neuropathy. However, sex differences in chronic pain and alcohol abuse are still not well understood. In the present study, we investigated whether chronic inflammatory pain using the inflammatory agent Complete Freund’s Adjuvant (CFA) model could alter ethanol consumption in male and female C57BL/6J mice. We observed that only CFA-treated male mice increased their ethanol …

Steamed Daylily Flower (Hemerocallis Fulva L.) Protected Cardiac And Hepatic Cells Against Ethanol Induced Apoptotic And Oxidative Damage, Sheng-Lei Yan, Wen-Tzu Wu, Mei-Chin Mong, Mei-Chin Yin

Journal of Food and Drug Analysis

Our previous study examined the phytochemical composition and bio-activities of raw daylily flower (Hemerocallis fulva L.). However, this plant food is usually served via heat process such as cooking in a soup. This study aimed to investigate the phytochemical profile and biofunctions of steamed daylily flower (SDF). The content of total phenolic acids, total flavonoids, total carotenoids, total anthocyanins and total triterpenoids in SDF aqueous extract was assessed. Normal cardiac and hepatic cells, H9c2 and L-02 cells, were used to evaluate the protective effects of SDF against ethanol. SDF concentrations of 0.25%, 0.5%, and 1% were applied to treat …

Rates of tobacco and alcohol use in women are rising, and women are more vulnerable than men to escalating tobacco and alcohol use. Many women use hormonal birth control, with the oral contraceptive pill being the most prevalent. Oral contraceptives contain both a progestin (synthetic progesterone) and a synthetic estrogen (ethinyl estradiol; EE) and are contraindicated for women over 35 years who smoke. Despite this, no studies have examined how synthetic contraceptive hormones impact this pattern of polysubstance use in females. To address this critical gap in the field, we treated ovary-intact female rats with either sesame oil (vehicle), the …

Selective Gsk3b Overexpression In Medial Prefrontal Cortex Camkiia Cells Produces Sex-Specific Changes In Ethanol Self-Administration, Anxiety-Like Behavior, And Working Memory, Sam Gottlieb, Zachary Tatom, Michael F. Miles

Graduate Research Posters

Background: Glycogen synthase kinase 3 beta (Gsk3b) is central in a gene network regulated by ethanol in mouse medial prefrontal cortex (mPFC). GSK3B abundance/activity modulations regulate ethanol consumption, suggesting GSK3B could be a target in treating alcohol use disorder. However, the critical cell type in this ethanol response is not yet known, nor have sex differences in GSK3B modulations been fully investigated. Here we report results of GSK3B overexpression selectively in CamKIIa⁺ mPFC cells on multiple behaviors.

Methods: Mice underwent stereotaxic injections to overexpress GSK3B in mPFC CamKIIa⁺ cells or control virus (n=4-6/sex/virus). We assayed working …

Characterization Of Acyclovir-Isonicotinamide Cocrystal By Solvent Evaporation Method With Ethanol And Glacial Acetic Acid, Hansen Pradana Sutedjo, Agnes Nuniek Winantari, Roisah Nawatila

The Thai Journal of Pharmaceutical Sciences

Background: Acyclovir is used as the first-line therapy for genital herpes simplex virus, but acyclovir has low solubility and bioavailability. Acyclovir has a water solubility of 2.5 mg/ml at 37°C and belongs to Class IV according to the bioavailability classification system. Cocrystalization is a technology that can be used to improve the solubility of materials by modifying the physical properties of materials, such as melting points, stability, mechanical properties, and polymorphisms of materials. Materials and Method: This study aims to prepare cocrystal of acyclovir with isonicotinamide as coformer using different solvents, namely, ethanol and glacial acetic acid by solvent evaporation …

Influence Of 2,5-Dimethoxy-4-Iodoamphetamine (Doi) On Ethanol Preference And Consumption In C57bl/6 Male Mice, Alaina M. Jaster, Sam Gottlieb, Michael Miles, Javier González-Maeso

Graduate Research Posters

Substance use disorders (SUD) account for a large number of mental health diagnosis in the United States and around the world. Approximately 13.6 million adults 26 or older and 5.1 million young adults (ages 18-24) battled with a SUD in 2017. Alcohol Use Disorder (AUD) alone effects nearly 6% of the adult population within the United States. This creates a substantial burden on the individual, with alcohol being the third-leading cause of preventable death in the United States. Few treatments for AUD exist, with no new FDA-approved therapeutic treatments within the last 15 years. Additionally, the limited treatments we do …

The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep

Theses and Dissertations

Chronic pain and excessive alcohol consumption are individually problems in our society today. Alcohol Use Disorder (AUD) affects 15.1 million adult Americans each year. Chronic pain affects over 100 million people annually in the United States. However, there is growing evidence suggesting that these two conditions can often be interrelated with chronic pain increasing consumption of alcohol, and excessive alcohol consumption increasing pain that leaves a feedback cycle trapping millions of patients in an ever worsening spiral. Large population-based studies show an association between pain and alcohol abuse, suggesting a link between increased alcohol use and reduced pain. While rodent …

Cellular And Molecular Mechanisms Underlying Alcohol-Induced Aggressiveness Of Breast Cancer, Yongchao Wang, Mei Xu, Zun-Ji Ke, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Breast cancer is a leading cause of morbidity and mortality in women. Both Epidemiological and experimental studies indicate a positive correlation between alcohol consumption and the risk of breast cancer. While alcohol exposure may promote the carcinogenesis or onset of breast cancer, it may as well enhance the progression and aggressiveness of existing mammary tumors. Recent progress in this line of research suggests that alcohol exposure is associated with invasive breast cancer and promotes the growth and metastasis of mammary tumors. There are multiple potential mechanisms involved in alcohol-stimulated progression and aggressiveness of breast cancer. Alcohol may increase the mobility …

Ethanol Reversal Of Oxycodone Tolerances, Joanna C. Jacob

Theses and Dissertations

Oxycodone is a semi-synthetic opioid originally developed as a safer alternative to morphine. It is commonly prescribed for its pain-relieving effects, but has recently been implicated as a major underlying cause of the current opioid epidemic due to its clinical limitations that include tolerance, dependence and a high abuse liability. Simultaneous consumption of opioids and ethanol has been shown to increase the risk of overdose and death from opioids in opioid-tolerant individuals. We hypothesized that ethanol reversed opioid tolerance and previous studies showed that ethanol reversed morphine tolerance. This dissertation investigated whether ethanol reversed tolerance to other opioids in mice, …

The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …
