Exploring Berberine As A Novel Therapeutic Agent Against Staphylococcus Aureus Infections: Targeting Inflammation And Antibiotic Resistance, Daniel Kopulos
Exploring Berberine As A Novel Therapeutic Agent Against Staphylococcus Aureus Infections: Targeting Inflammation And Antibiotic Resistance, Daniel Kopulos
NYMC Student Theses and Dissertations
Staphylococcus aureus is a versatile Gram-positive bacterium commonly found on human skin. While often harmless, it can cause various infections when the skin is compromised, ranging from minor issues to life-threatening conditions in immunocompromised individuals.
The bacterium’s ability to resist antibiotics, particularly methicillin, underscores its clinical challenge. Staphylococcus aureus can also acquire vancomycin resistance. It evades immune responses through multiple mechanisms, including capsule formation, interference with immune proteins like staphylococcal protein A, and secretion of toxins such as Panton-Valentine Leukocidin. Understanding these mechanisms is crucial for developing effective strategies against Staphylococcus aureus infections.
The immune response to Staphylococcus aureus infections …
The Interplay Of Gut Microbiota And Their Metabolites As Potential Regulators Of Resilience Or Susceptibility To Traumatic Stress In Male And Female Rats, Arax Tanelian
NYMC Student Theses and Dissertations
Exposure to traumatic stress is a major risk factor for the development of mood disorders in a subpopulation of individuals, while others remain resilient. Notably, women are twice as likely as men to develop affective disorders in the aftermath of trauma. The mechanisms and contributing factors that influence sex-related disparities in mood disorders and variations in resilience remain unclear. We hypothesized that sex-specific inter-individual differences in microbial composition, functionality, and metabolites would contribute to host resilience or susceptibility to stress-induced psychopathologies. In this study, we used single prolonged stress (SPS), an animal model of Post- Traumatic Stress Disorder (PTSD), to …
Neuromodulation Of Mouse Auditory Cortex Using Focused Ultrasound, Jacob Hehir
Neuromodulation Of Mouse Auditory Cortex Using Focused Ultrasound, Jacob Hehir
NYMC Student Theses and Dissertations
Neurological diseases impose a large health and financial burden for nations worldwide. Current treatments for many conditions are limited to pharmacological or invasive surgical approaches. Neuromodulation is an alternative therapy wherein electrical currents, magnetic fields, or electromagnetic waves are used to noninvasively modify brain function. Focused ultrasound (FUS) has been shown to alter neural activity, theoretically with much higher spatial resolution than other neuromodulation techniques. However, these predictions assume that neuromodulatory effects are constrained to the acoustic focus. Given that the architecture of neural circuitry in the cerebral cortex supports delicately balanced lateral processing on spatial scales that may exceed …
Remodeling Anaplastic Thyroid Cancer's Aggressive Profile And Metabolic Signature By Natural Alkaloid Berberine, Tara Elizabeth Jarboe
Remodeling Anaplastic Thyroid Cancer's Aggressive Profile And Metabolic Signature By Natural Alkaloid Berberine, Tara Elizabeth Jarboe
NYMC Student Theses and Dissertations
Anaplastic thyroid cancer is a rare, fatal cancer with a five-year survival of 4%. Universally diagnosed at stage IV, anaplastic thyroid cancer is characterized by its lack of differentiation, rapid proliferative rate, highly inflammatory tumor microenvironment, and metabolic dysregulation. Refractory to all established therapies, anaplastic thyroid cancer requires a novel therapeutic approach that targets all of these drivers of anaplastic thyroid cancer carcinogenesis. We propose natural alkaloid berberine as a therapeutic with multitarget efficacy to alter mitochondrial metabolism and reprogram anaplastic thyroid cancer’s aggressive phenotype. Our in vitro model uses monocyte cell line U937, anaplastic thyroid cancer cell lines T238 …
