Jatropha Tanjorensis A Flora Of Southeast Nigeria: Isolation And Characterization Of Naringenin And Validation Of Bio-Enhanced Synergistical Activity Of Α- Tocopherol Toward Clinical Isolates Of Resistant Bacterial, Ikechukwu Kingsley Ijoma, Vincent Ishmael Egbulefu Ajiwe

Makara Journal of Science

Jatropha tanjorensis is among the rich floras of Southeast Nigeria and used by ethnic people to treat infections and manage health conditions. Ethnomedicine has long been employed in the treatment of ailments caused by bacterial pathogens. Studies showed that the incorporation of synthetic α-tocopherol to an antibacterial agent improves its activity. However, knowledge about the antibacterial-enhanced activity of plant-based α-tocopherols, especially those isolated from Jatropha tanjorensis, is limited because of the different bioactivities of synthetic and natural α-tocopherols. To determine the phytochemicals in J. tanjorensis, we carried out the structural elucidation of its leaf extracts. Naringenin and α-tocopherol …

Multimodal Approach To Chronic Pain Management And Prevention Of Opioid Use Disorder, Hannah Elston

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background. Chronic pain (CP) is a major public health problem that affects one-third of the population and can interfere with the activities of daily life and cause decreased quality of life. Patients with CP have been increasingly prescribed opioids, contributing to the rise in the opioid epidemic. Due to the long-term nature of CP, the use of opioids as the sole treatment for CP can cause tolerance and increased dosages overtime which can lead to addiction and potentially overdose. Therefore, CP treatment should include multimodal approaches to treatment to prevent opioid misuse, opioid use disorder (OUD), and overdose. Multimodal treatments …

Hendy, Mariam M. Tadros

Pharmacy

Abstract: The authors in the current work suggested the potential repurposing of omarigliptin (OMR) for neurodegenerative diseases based on three new findings that support the preliminary finding of crossing BBB after a single dose study in the literature. The first finding is the positive results of the docking study with the crystal structures of A2A adenosine (A2AAR) and acetylcholine esterase (AChE) receptors. A2AAR is a member of non-dopaminergic GPCR superfamily receptor proteins and has essential role in regulation of glutamate and dopamine release in Parkinson’s disease while AChE plays a major role in Alzheimer’s disease as the primary enzyme responsible …

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 …

Integration Of Native American Medicinal Plants Into The Heber W. Youngken Jr. Garden, Emily Lyn Murray

Senior Honors Projects

Healthcare among Native American tribes was focused on all aspects of a patient’s life, such as physical, spiritual, and environmental elements. Healthy outcomes were obtained by maintaining a balance among all of these components. This “bio-psycho-socio-spiritual” approach to healthcare was thought to not only play a role in the health of a certain individual, but the health of the tribe as a whole. An illness was not only precipitated by a physical source, but by an imbalance of these components. Medicinal plants served as an integral role in direct physical healing, as well as an important element for the execution …

Target-Directed Biosynthetic Evolution: Redirecting Plant Evolution To Genomically Optimize A Plant’S Pharmacological Profile, Dustin Paul Brown

Theses and Dissertations--Neuroscience

The dissertation describes a novel method for plant drug discovery based on mutation and selection of plant cells. Despite the industry focus on chemical synthesis, plants remain a source of potent and complex bioactive metabolites. Many of these have evolved as defensive compounds targeted on key proteins in the CNS of herbivorous insects, for example the insect dopamine transporter (DAT). Because of homology with the human DAT protein some of these metabolites have high abuse potential, but others may be valuable in treating drug dependence. This dissertation redirects the evolution of a native Lobelia species toward metabolites with greater activity …

Feasibility Of Integrating Tripterygium Wilfordii Into Modern Cancer Therapy For Increased Efficacy And Minimal Toxicity, Ngoc T. Vo

Undergraduate Research Posters

Cancer is the second leading cause of death in the U.S. and millions of novel cancer cases are being diagnosed each year. While chemotherapy and ionizing radiation are effective treatments against these malignant tumors, the adverse effects that accompany such treatments are devastating. In order to find alternative treatment methods with less side effects, we turn to Eastern herbal medicine. Recent scientific research has found that Tripterygium wilfordii, an herbal medicine traditionally used to treat inflammation in China, contains compounds (triptolide and celastrol) that prevent the growth of solid tumors, induce apoptosis, and prevent metastasis of developed tumors. Investigations …

Discovery Of Quinic Acid Derivatives As Oral Anti-Inflammatory Agents, Kui Zeng

Theses and Dissertations (ETD)

Quinic acid (QA) esters found in hot water extracts of Uncaria tomentosa (a.k.a. Cat’s claw) exert anti-inflammatory activity through mechanisms involving inhibition of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB). Herein, we described the synthesis and biological testing of novel QA derivatives. Inhibition of NF-κB was assessed using A549 (Type II alveolar epithelial-like) cells that stably express a secreted alkaline phosphatase (SEAP) reporter driven by an NF-κB response element. A549- NF-κB cells were stimulated with TNF-α (10 ng/mL) in the presence or absence of QA derivative for 18 hours followed by measurement of SEAP activity. Amide substitution at …

Antibiotics, Herbs, And Magic: Health Practices In Contemporary St. Petersburg, Christine Shu

Honors Theses

In St. Petersburg, Russia, two seemingly conflicting health doctrines, western medicine and alternative medicine, play significant roles in residents' health culture. I define alternative medicine as all health practices that use such natural products as herbs, natural honey, water, seeds, berries, and even animal products, and as such unobtrusive body therapies as acupuncture, massage, yoga, or animal therapies. I define western medicine as all treatments that involve the manipulation of ingredients in a chemistry laboratory (such as antibiotics, antiviral drugs, antihistamines. or pain killers) and all body therapies intrusive to the body (such as operations). Through interviews with St. Petersburg …

Computational Studies Of Melatonin Analogues, Jessica Lynne Baima

Honors Theses

Melatonin (MLT, N-Acetyl-5-methoxytryptamine), a naturally occurring hormone produced by the pineal gland, plays a crucial role in the regulation of circadian rhythms. Melatonin supplements are utilized in treating various sleep disorders, but detrimental side effects currently discourages its use in space. Computer generated molecular models of MLT analogues were studied with the purpose of resolving the deficiencies within existing therapeutic agents by constructing an enhanced MLT analogue. The MT receptor binding data for each analogue was obtained from the literature and Sybyl 6.9 was used to perform 3-D quantitative structure-activity relationship (QSAR) studies on eight data sets, using the comparative …
