Essentials Of Herb-Drug Interactions In The Elderly With Cardiovascular Disease, Sulaiman Sultan, Maria Viqar, Rabaiya Ali, A. Jamil Tajik, Arshad Jahangir
Essentials Of Herb-Drug Interactions In The Elderly With Cardiovascular Disease, Sulaiman Sultan, Maria Viqar, Rabaiya Ali, A. Jamil Tajik, Arshad Jahangir
Arshad Jahangir, MD
As the number of individuals, particularly the elderly, using herbal products with prescription drugs continues to grow, the risk for adverse interactions increases but remains poorly recognized. The true incidence and nature of adverse herb reactions or herb-drug interactions remains unknown since no postmarketing surveillance mechanism exists. Adverse events are greatly underreported, and information regarding safety mainly comes from case reports and suboptimally conducted studies in a limited number of healthy young volunteers or patients with limited comorbidities. Therefore, convincing evidence for the safety of herbal products in the elderly is lacking, and the true magnitude of problems that herb-drug …
Effects Of Moderate Intake Of Alcohol On Coronary Heart Disease, Eli Derdik
Effects Of Moderate Intake Of Alcohol On Coronary Heart Disease, Eli Derdik
The Science Journal of the Lander College of Arts and Sciences
The french paradox is caused by an inconsistency with scientific experimentation: The French have a very high intake of saturated fat and cholesterol, which is associated with coronary heart disease, yet they have un-commensurately low levels of deaths due to this disease. It has been proposed that alcohol, as a part of the French diet, is the factor that helps decrease the risk of heart disease in the French population by 20-30%. Research has been gathered from many medical journals to create a larger and more accurate perspective to determine if alcohol has any effect on coronary heart disease. Experiments …
Effects Of Nox-1 Inhibition On Real-Time Blood Nitric Oxide And Hydrogen Peroxide In Acute Hyperglycemia, Ashley Mawhinney
Effects Of Nox-1 Inhibition On Real-Time Blood Nitric Oxide And Hydrogen Peroxide In Acute Hyperglycemia, Ashley Mawhinney
PCOM Biomedical Studies Student Scholarship
Hyperglycemia has been associated with vascular endothelial dysfunction in part by a reduction in nitric oxide (NO) production and increased oxidative stress (e.g., increased superoxide (SO) and hydrogen peroxide (H2O2). Endothelial-derived NO can be significantly reduced by increased SO/H2O2 in part by the activation of NADPH oxidase during hyperglycemia. Of the 7 NADPH oxidase isoforms, NADPH oxidase isoform 1 (NOX1) is mainly expressed in the vasculature and may play a major role in hyperglycemia induced oxidative stress and vascular endothelial dysfunction. This hypothesis was tested by measuring blood NO and H2O2 levels in …

Accidental Phosphine Gas Poisoning With Fatal Myocardial Dysfunction In Two Families, Saleem Akhtar, Arshalooz Rehman, Surraya Bano, Anwarul Haque
Accidental Phosphine Gas Poisoning With Fatal Myocardial Dysfunction In Two Families, Saleem Akhtar, Arshalooz Rehman, Surraya Bano, Anwarul Haque
Department of Emergency Medicine
ABSTRACT Aluminum phosphide is commonly used as a rodenticide and insecticide and is one of the most fatal poisons. The active ingredient is Phosphine gas which inhibits cytochrome oxidase and cellular oxygen utilization. The clinical symptoms are due to multiorgan involvement including cardiac toxicity which is the most common cause of mortality. Severity of clinical manifestations depends upon the amount of the gas to which a person is exposed. There is no specific antidote available. High index of suspicion and early aggressive treatment is the key to success. We report 2 cases of aluminum phosphide toxicity in 2 families due …
Genomic Predictors Of Drug Response To The Alpha-Specific Phosphoinositol 3-Kinase (Pi3ka-Alpha) Inhibitor Byl719 In Head And Neck Cancers, Giananthony T. Rizzo
Genomic Predictors Of Drug Response To The Alpha-Specific Phosphoinositol 3-Kinase (Pi3ka-Alpha) Inhibitor Byl719 In Head And Neck Cancers, Giananthony T. Rizzo
Electronic Thesis and Dissertation Repository
PIK3CA is the only frequently mutated, druggable oncogene in head and neck squamous cell cancer (HNSCC), with PIK3CA point mutations and gene amplification rates of 17.5% and 40% respectively, with higher rates in HPV-positive disease. The objective of this research was to determine the effects of BYL719, an α-specific PI3K inhibitor in HNSCC cell lines.
All cell lines with PIK3CA hotspot point mutations or gene amplifications will be sensitive to BYL719.
Twenty-eight HNSCC cell lines were subjected to increasing concentrations of BYL719 and cell viability was measured over time. Cell lines were screened for activating PIK3CA hotspot mutations and amplifications …

Background: Aberrant energy metabolism is a hallmark of cancer. To fulfill the increased energy requirements, tumor cells secrete cytokines/factors inducing muscle and fat degradation in cancer patients, a condition known as cancer cachexia. It accounts for nearly 20% of all cancer-related deaths. However, the mechanistic basis of cancer cachexia and therapies targeting cancer cachexia thus far remain elusive. A ketogenic diet, a high-fat and low-carbohydrate diet that elevates circulating levels of ketone bodies (i.e., acetoacetate, β-hydroxybutyrate, and acetone), serves as an alternative energy source. It has also been proposed that a ketogenic diet leads to systemic metabolic changes. Keeping in …
The Effects Of Dihydrobiopterin And Tetrahydrobiopterin On Hydrogen Peroxide And Nitric Oxide Release During Extracorporeal Shockwave Lithotripsy (Eswl), Brittany Deiling
The Effects Of Dihydrobiopterin And Tetrahydrobiopterin On Hydrogen Peroxide And Nitric Oxide Release During Extracorporeal Shockwave Lithotripsy (Eswl), Brittany Deiling
PCOM Biomedical Studies Student Scholarship
ESWL is an effective, non-invasive therapy utilized to fragment stones in the kidney and subsequently be cleared in the urinary tract. Although lithotripsy provides a safer alternative to invasive treatments for removing stones, ESWL may cause vasoconstriction after ESWL treatment, reducing renal blood flow, which can cause kidney damage leading to acute to chronic hypertension clinically. This may be due to kidney vascular endothelial dysfunction, which is characterized as increased oxidative stress and decreased endothelial nitric oxide synthase (eNOS)-derived nitric oxide (NO) bioavailability. We hypothesized that ESWL would decrease NO and increase hydrogen peroxide (H2O2) in …
Attenuating Trigeminal Neuropathic Pain By Repurposing Pioglitazone And D-Cycloserine In The Novel Trigeminal Inflammatory Compression Mouse Model, Danielle N. Lyons
Attenuating Trigeminal Neuropathic Pain By Repurposing Pioglitazone And D-Cycloserine In The Novel Trigeminal Inflammatory Compression Mouse Model, Danielle N. Lyons
Theses and Dissertations--Physiology
Approximately 22% of the United States population suffers from a chronic orofacial pain condition. One such condition is known as trigeminal neuropathic pain frequently reported as continuous aching and burning pain, often accompanied by intermittent electrical shock-like sensations. Dental procedures or trauma are known causes of peripheral trigeminal nerve injury and inflammation. Patients who have this type of facial pain also suffer from emotional distress. For these reasons, trigeminal neuropathic pain needs to be studied in more detail to improve the understanding of the etiology and maintenance of this condition, as well as to develop effective treatment strategies. The first …

Synthesis And Polarographic Analysis Of A2e, Elise Rivett
Honors Program Projects
As humans age, fluorescent retinoid pigments accumulate in the retinal pigment epithelial (RPE) cells responsible for photoreceptor support. These fluorophores are of interest because they seem to contribute to diseases of the retina, particularly age-related macular degeneration, which is a leading cause of blindness in older adults in the United States and currently has no cure. One well-characterized fluorophore, A2E, can be oxidized by visible light and then generate harmful oxidative species capable of inducing programmed cell death in RPE cells. Further characterization of the redox behavior of A2E could ultimately aid the development of macular degeneration treatments designed to …
Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King
Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King
Masters Theses & Specialist Projects
Studies reporting a high concentration of WR-2721 in mouse salivary glands led to our studies of possible radioprotection of these glands by this drug from ionizing radiation. Oral effects of radiation in the presence of WR-2721 were studied in mice and dogs. Histological evaluation of mouse salivary glands irradiated with 1000 rads of 60Co showed essentially no difference between control and experimental animals. Almost full regeneration of the serous salivary components occurred by 6 months in both groups and neither group had changes in the mucous glands. The use of higher doses of radiation in the mouse was prevented …
