The Effect Of Depression Symptoms On The Cardiac Autonomic Response To Positive Mood Induction, Elizabeth Golias, Khadeja Najjar, Brock Bodenbender Jan 2015

The Effect Of Depression Symptoms On The Cardiac Autonomic Response To Positive Mood Induction, Elizabeth Golias, Khadeja Najjar, Brock Bodenbender

Depression is characterized by a reduced capacity to experience pleasure (hedonic capacity). A growing literature suggests that hedonic capacity is supported by the sympathetic (SNS) and parasympathetic (PNS) branches of the autonomic nervous system. Both branches may work in a reciprocal fashion, or in tandem, reflecting co-activation of the SNS and PNS. While reduced PNS and increased SNS activity are associated with happy states among healthy individuals, preliminary findings suggest that depressed persons evidence blunted physiologic responses across a variety of emotion inducing stimuli. Much of this work, however, has examined PNS and SNS activity separately, and never with respect …


Autonomic Nervous System Response To Interpersonal Exclusion In Borderline Personality Disorder, Ilona Ponomariova, Brock Bodenbender, Khadeja Najjar, Elizabeth Golias Jan 2015

Autonomic Nervous System Response To Interpersonal Exclusion In Borderline Personality Disorder, Ilona Ponomariova, Brock Bodenbender, Khadeja Najjar, Elizabeth Golias

Intense emotional reactions to interpersonal rejection reflect the core of Borderline Personality Disorder (BPD). These reactions supported by the autonomic nervous system (ANS), which has been linked to neural regions that undergird emotional experience and regulation that are affected among individuals with BPD. Despite such links, relatively few studies have examined ANS functioning among BPD populations. The few studies that have primarily focused on the independent activity of the two sympathetic (SNS) and parasympathetic (PNS) ANS branches during resting states or in response to emotion evocative films, rather than to interpersonal rejection. The present study overcomes the above noted gaps …


Cultural Differences In Coping And Depression Between Individuals Of Middle-Eastern And Non-Arab Backgrounds, Khadeja Najjar Jan 2015

Cultural Differences In Coping And Depression Between Individuals Of Middle-Eastern And Non-Arab Backgrounds, Khadeja Najjar

Undergraduate Research Posters 2015

The Middle Eastern (Arab) demographic is a growing, yet neglected cultural group in mental health research. While Arabs are more predisposed to depression than other ethnic groups in US, little is known about mechanisms that account for this risk. One set of mechanisms may be the use of ineffective (maladaptive) coping or insufficient use of effective (adaptive) coping responses, which are robust predictors of depression in US samples, but virtually unexamined in Arabs. Further, the effect of a coping is influenced by culture, which, for Arabs, may change as a function of acculturation. Thus, the present study aimed to examine …


Enhancement Of Solar Energy Conversion In Bio-Derived Cells Via Side Selective Modification Of Photosystem I, Uchechukwu Obiako, Evan Gizzie Jan 2015

Enhancement Of Solar Energy Conversion In Bio-Derived Cells Via Side Selective Modification Of Photosystem I, Uchechukwu Obiako, Evan Gizzie

Undergraduate Research Posters 2015

Deleterious effects of some methods used to harness energy from the environment today have garnered the exploration of safer and more reliable options, specifically solar energy conversion. Current solar cell technology has yielded quantum efficiencies commonly in the range of 10-20% but is limited by extensive processing methods, high cost, and need for rare materials. However, bio-derived solar cells containing Photosystem I (PSI) address these problems as PSI is highly abundant, very efficient, and low-cost. PSI acts as a biomolecular photodiode through rapid photoexcited charge separation, making it very promising for use as an integral element in solar cells. To …

For all microorganisms, acquisition of metal ions is essential for survival in the environment or their infected host. Metal ions are required in many biological processes as cofactors for proteins or structural elements for enzymes. These ions play a role in chemotaxis, phosphorylation, transport of sugars and proteins, and initiation of DNA replication, among other things. It is critical for bacteria to ensure that metal uptake and availability meet its physiological needs; too little can impede these important biological processes, while too much can be toxic leading to radical formation which can cause damage to proteins and cell structures (Porcheron, …


Feasibility And Effects Of Accelerometer Based Feedback On Paretic Upper Extremity Amount Of Use In The Home Setting In Subjects Chronic Post-Stroke, Nathan Pohl, Amber Kuehn, Mishgan Abdullah Jan 2015

Feasibility And Effects Of Accelerometer Based Feedback On Paretic Upper Extremity Amount Of Use In The Home Setting In Subjects Chronic Post-Stroke, Nathan Pohl, Amber Kuehn, Mishgan Abdullah

Undergraduate Research Posters 2015

Purpose : to (1) evaluate the feasibility of using accelerometers in the home to quantify how much subjects chronic post-stroke (PS) use their upper extremities (UE), (2) measure differences between amount of UE movement in subjects PS and a healthy control group (HC), (3) determine the effects of accelerometer based feedback on paretic UE use in subjects PS, and (4) determine if those effects are retained over time. Methods : Six subjects PS wore accelerometers for 3 weeks with two feedback sessions given during week two. Seven HC subjects wore accelerometers for one week. Accelerometer based outcome measures included relative …


Effects Of Accelerometer Based Feedback On Clinical Measures And Paretic Upper Extremity Amount Of Use In Subjects Chronic Post-Stroke, Amber Kuehn, Nathan Pohl, Mishgan Abdullah Jan 2015

Effects Of Accelerometer Based Feedback On Clinical Measures And Paretic Upper Extremity Amount Of Use In Subjects Chronic Post-Stroke, Amber Kuehn, Nathan Pohl, Mishgan Abdullah

Undergraduate Research Posters 2015

Purpose/Hypothesis: To determine the effects of accelerometer based feedback on clinical measures of paretic upper extremity (UE) recovery in people post-stroke and examine the relationship between these changes and paretic UE amount of use (AOU) measured by an accelerometer. Subjects: 7 people chronic post-stroke (5 males, 2 females; aged 62.03 ± 11.33 years) with an Upper Extremity Fugl-Meyer score range of 10-63 were included for this poster. Materials/Methods: Subjects wore wrist accelerometers for 3 weeks in the home. Clinical measures (Motor Activity Log, Stroke Impact Scale, Chedoke Arm and Hand Activity Inventory, and the ABILHAND) were assessed weekly. Data analysis …
