Targeting Cancer Stem Cells In Recurrent Lung Cancer, Karen T. Udoh

Posters-at-the-Capitol

Lung cancer is the leading cause of cancer mortality in the world. Five-year survivability still remains dismal due to drug resistance. The development of drug resistance with cisplatin or platinum/taxane combination chemotherapies has led patients to suffer from recurrent lung cancer. These chemotherapy treatments target cancer cells but leave behind cancer stem cells. Cancer stem cells (CSCs) are stem-like tumor cells that have the potential to differentiate, self-renew, and proliferate. This allows the cancer to relapse even after initial elimination of the tumor. We hypothesize that Verrucarin J will inhibit cell proliferation in lung cancer cells and CSCs by inducing …

Disruption Of Hippocampal Multisynaptic Networks By General Anesthetics., Min-Ching Kuo, L Stan Leung

Physiology and Pharmacology Publications

BACKGROUND: Previous studies showed that synaptic transmission is affected by general anesthetics, but an anesthetic dose response in freely moving animals has not been done. The hippocampus provides a neural network for the evaluation of isoflurane and pentobarbital on multisynaptic transmission that is relevant to memory function.

METHODS: Male Long-Evans rats were implanted with multichannel and single electrodes in the hippocampus. Spontaneous local field potentials and evoked field potentials were recorded in freely behaving rats before (baseline) and after various doses of isoflurane (0.25 to 1.5%) and sodium pentobarbital (10 mg/kg intraperitoneal).

RESULTS: Monosynaptic population excitatory postsynaptic potentials at the …

Finasteride As A Model For Personalized Medicine, Ion G. Motofei, David L. Rowland, Ioana Păunică, Octavian C. Tănăsescu, Petrişor Banu, Stana Păunică

Journal of Mind and Medical Sciences

The side effects of Finasteride are currently a subject of controversy. Some studies report minor or acceptable adverse effects, which decrease after a variable period of time so that they do not necessitate terminating Finasteride administration. However, several clinical and neuro-endocrine studies show that some adverse effects persist indefinitely in the form of post-Finasteride syndrome, even after the drug cessation. This paper presents a possible explanation for these inconsistent findings. First, the study design of either informing or not informing patients prior therapy about possible adverse effects can influence the incidence and magnitude of reported adverse effects. Second, structural and …

Enduring Chronic Kidney Disease: An Investigation Of Psychosocial Factors And Life Satisfaction In Older Adults Receiving Dialysis Treatment, Bailee Sobotka

Honors Theses

Chronic kidney disease is a condition during which the kidneys begin to shut down and no longer filter blood efficiently. Once the disease has progressed far enough, dialysis treatments are mandatory to sustain life. To further understand how older adults receiving dialysis treatments cope with their disease, psychosocial factors were evaluated to investigate possible correlations with life satisfaction using a Life Satisfaction Index Z (LSI-Z). Expected correlations with life satisfaction were sociability, financial satisfaction, importance of spirituality, and activities of daily living scores. Interviews were conducted with 30 dialysis patients and results were analyzed using various statistical measures. Significant correlations …

Brain Microvascular Injury And White Matter Disease Provoked By Diabetes-Associated Hyperamylinemia, Han Ly, Nirmal Verma, Fengen Wu, Miao Liu, Kathryn E. Saatman, Peter T. Nelson, John T. Slevin, Larry B. Goldstein, Geert Jan Biessels, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

OBJECTIVE: The brain blood vessels of patients with type 2 diabetes and dementia have deposition of amylin, an amyloidogenic hormone cosecreted with insulin. It is not known whether vascular amylin deposition is a consequence or a trigger of vascular injury. We tested the hypothesis that the vascular amylin deposits cause endothelial dysfunction and microvascular injury and are modulated by amylin transport in the brain via plasma apolipoproteins.

METHODS: Rats overexpressing amyloidogenic (human) amylin in the pancreas (HIP rats) and amylin knockout (AKO) rats intravenously infused with aggregated amylin were used for in vivo phenotyping. We also carried out biochemical analyses …

Local Anesthesia Toxicity, Nicole Mccleery

Nursing Student Class Projects (Formerly MSN)

Local anesthesia (LA) provides a way to relieve temporary pain in a small part of the body and has been used for over 100 years (Fencl, 2015). LA also prevents the passage of surgical stimuli into the central nervous system (CNS) making a surgical procedure less painful for the patient (Noble, 2015). According to Noble, “altering the passage of stimuli from smaller diameter neurons in a confined area with lower drug dosages is called LA, such as the injection of LA around a surgical incision” (Noble, 2015, p.325). LA can be used in a variety of settings, such as in …
