Who Wears Me? Bioimpedance As A Passive Biometric, Cory Cornelius, Jacob Sorber, Ronald Peterson, Joe Skinner, Ryan Halter, David Kotz

Dartmouth Scholarship

Mobile and wearable systems for monitoring health are becoming common. If such an mHealth system knows the identity of its wearer, the system can properly label and store data collected by the system. Existing recognition schemes for such mobile applications and pervasive devices are not particularly usable – they require ıt active engagement with the person (e.g., the input of passwords), or they are too easy to fool (e.g., they depend on the presence of a device that is easily stolen or lost). \par We present a wearable sensor to passively recognize people. Our sensor uses the unique electrical properties …

Iron Homeostasis During Cystic Fibrosis Pulmonary Exacerbation, Alex H. Gifford, Lisa A. Moulton, Dana B. Dorman, Gordana Olbina, Mark Westerman, H. Worth Parker, Bruce Stanton, George A. O'Toole

Dartmouth Scholarship

BACKGROUND:

Hypoferremia is a marker of disease severity in cystic fibrosis (CF). The effect of systemic antibiotics on iron homeostasis during CF pulmonary exacerbation (CFPE) is unknown. Our central hypotheses were that, by the completion of treatment, serum iron would increase, serum concentrations of interleukin-6 (IL-6) and hepcidin-25, two mediators of hypoferremia, would decrease, and sputum iron would decrease.

METHODS:

Blood and sputum samples were collected from 12 subjects with moderate-to-severe CF (median percentage-predicted forced expiratory volume in 1 second (FEV(1) %) = 29%; median weight = 56 kg) within 24 hours of starting and completing a course of systemic …

The Real-Time Measurements Of Blood Nitric Oxide (No) And Hydrogen Peroxide (H2o2) Levels Under Acute Hyperglycemia, Michael Minni

PCOM Biomedical Studies Student Scholarship

Vascular endothelial dysfunction is one of the earliest recognizable events under hyperglycemic conditions. It is characterized by decreased endothelium-derived nitric oxide (NO) bioavailability and increased oxidative stress, such as superoxide and hydrogen peroxide (H2O2) overproduction. However, the real-time changes in blood NO and H2O2 levels under acute hyperglycemia have not been evaluated. In this study, acute hyperglycemia (200 mg/dl, 400 mg/dL, and 600 mg/dL) was induced by intravenous infusion of 20%, 30%, and 50% D-glucose respectively for 180 min. Infusion of saline or 30% L-glucose serve as controls. Blood NO or H2 …


The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume Aug 2012

The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume

Graduate Theses and Dissertations

Postmenopausal osteoporosis is the most prevalent form of osteoporosis and results in fragility fractures. Smoking is one of the major risk factors for osteoporosis and is known to aggravate bone loss in postmenopausal women due to increased oxidative stress and inflammation. Diet-based interventions using berries have shown bone protective affects in animal studies partially due to antioxidant and anti-inflammatory properties of their phenolic compounds. The goal of this research was to determine the effects of antioxidant-rich fruits in the prevention of postmenopausal bone loss. Our first study examined the dose dependent effects of blackberries in preventing bone loss in an …


Does Psychopathy Predict Future Risky Sexual Behavior?, Jessica Jade Fulton Aug 2012

Does Psychopathy Predict Future Risky Sexual Behavior?, Jessica Jade Fulton

Dissertations

Risky sexual behavior (RSB), such as having sex with an unknown partner, is associated with a variety of negative consequences including sexually transmitted diseases and unplanned pregnancy. Previous research (e.g., Fulton, Marcus, & Payne, 2010) suggests that psychopathic personality traits as assessed by the Psychopathic Personality Inventory (Lilienfeld & Andrews, 1996) are associated with RSB. Self-Centered Impulsivity (SCI), which is characterized by impulsivity, irresponsibility, and reckless behavior, was positively associated with RSB among men and women. In contrast, Fearless Dominance (FD), which is characterized by fearlessness, manipulativeness, and social dominance, was positively associated with RSB among men but not women. …


Integrating Care: Improving Overall Health By Integrating Behavioral/Mental Health Care Into Primary Care, Macaran A. Baird Aug 2012

Integrating Care: Improving Overall Health By Integrating Behavioral/Mental Health Care Into Primary Care, Macaran A. Baird

Center for Policy Research

Hippocrates noted that the patient must be attended in light of “his” diet, work, home, and community setting. Since that time, we have struggled with the dilemma of how to put the patient’s presenting problems in the context of the patient’s life circumstances. That goal has proven elusive. So how do we sort out where to put the emphasis with our healing arts?
