The Last Of Us In Therapy: How Mind-Controlling Fungi And Gut Bacteria Affect Your Mental Health, Anastasia Lyon May 2023

The Last Of Us In Therapy: How Mind-Controlling Fungi And Gut Bacteria Affect Your Mental Health, Anastasia Lyon

Journal of Pharmacology & Nutritional Sciences

The "psilocybiome" represents the mutually beneficial relationship between ourselves, our bacteria, and psychedelic drugs. This short review briefly discusses the benefits and limitations surrounding the potential for psychedelic therapy to synergize with gut bacteria to help regulate and maintain proper balance in the immune system, diet, and stress levels. Psychedelic therapy is a novel treatment strategy that has the potential to improve patient mental health, and, by identifying the types of gut bacteria present in patients, it can aid in personalizing medicine by determining how well their "psilocybiome" may respond.


Fecal Microbiota Transplantation And Gut Microbiome Effects On Psychiatric Illnesses, Mona Seresht Jun 2020

Fecal Microbiota Transplantation And Gut Microbiome Effects On Psychiatric Illnesses, Mona Seresht

Physician Assistant Studies | Student Articles

Despite the medical advances that have been made in regards to mental health, psychiatric medications, and alternative therapies, many patients continue to suffer day in and day out, unable to live the type of life they desire. Many times, the medication route includes many episodes of trial and error, side effects, and no significant improvement in actual symptoms. Therapy, although effective, typically necessitates a supplemental medication for the best results. Fecal microbiota transplantation (FMT) is a method where feces from a healthy donor is transferred to an affected patient, typically via colonoscopy. Theoretically, this alters the gut microbiome in a …


Discovery Of Distinct Mechanisms Underlying The Relationship Between Drug Taking And Predisposing Behaviors, Tyler A. Roy May 2020

Discovery Of Distinct Mechanisms Underlying The Relationship Between Drug Taking And Predisposing Behaviors, Tyler A. Roy

Electronic Theses and Dissertations

Drug addiction is a heritable disease characterized by compulsive drug use. The biological mechanisms driving addiction remain largely unknown.1 Previous studies show shared genetic mechanisms underlying addiction risk phenotypes such as anxiety, depression, and novelty/sensation seeking.2,3 Therefore, high-throughput behavioral screening of these traits in single gene knockout mice can allow for the rapid detection of addiction risk candidate genes and mechanisms. Many of these traits are represented in the Knock-Out Mouse Program (KOMP) phenotyping pipeline. Of the initial two hundred twenty-one strains screened in this program, we tested nineteen phenodeviant knock-out mouse strains with C57BL/6NJ controls (N = …


Effects Of (R,S)-Ketamine And (2r,6r)-Hydroxynorketamine: A Preclinical Study, Remington Rice Jan 2020

Effects Of (R,S)-Ketamine And (2r,6r)-Hydroxynorketamine: A Preclinical Study, Remington Rice

Theses and Dissertations

In 2017, 7.1% of US adults were diagnosed with depression, and 50% of patients received medication to treat their depression. Depression can cause severe interruptions in an individual's cognitive functioning and behaviors like sleeping, eating, working, and socializing. Unfortunately, approximately 40% of patients do not respond to treatment with monoaminergic medications (e.g. Prozac) and therapeutic effects may be delayed 2-8 weeks. Due to these therapeutic shortcomings, faster acting and more efficacious treatments are needed. Recent preclinical findings indicate potential for glutamatergic drugs like (R,S)-ketamine and (2R,6R) hydroxynorketamine to produce more rapid and longer-acting therapeutic effects. The antidepressant effectiveness of (R,S)-ketamine …


An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings May 2017

An Analysis Of Neurogenesis In A Mouse Model Of Chemotherapy Related Cognitive Impairment, Maxwell A. Hennings

Electronic Theses and Dissertations

Cancer patients treated with adjuvant chemotherapy often experience cognitive decline following treatment. This phenomenon, often dubbed “chemo brain” or “chemo fog” is usually temporary, but for a subset of survivors, these cognitive impairments can be long-lasting (>10 years) and negatively affect patients’ quality of life, career performance, and social fulfillment. While it is unclear what neurobiological mechanisms underlie chemotherapy related cognitive impairment, the majority of the animal literature has focused on adult neurogenesis. One process important for neurogenesis is the proliferation of new neurons within the dentate gyrus of the hippocampus. It is evident that many chemotherapy agents can …
