Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi
Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi
Honors Theses
Household/commercial bleach (6% NaOCl, sodium hypochlorite) degrades DNA through oxidative damage, production of chlorinated base products, and cleavage of DNA strands (breaking it into smaller and smaller fragments). The presence of these lesions significantly impacts the ability to generate a full genetic profile from an evidentiary sample. In fact, knowledge of the damaging effect of bleach on DNA is the basis for its use in forensic laboratories to clean workbenches and prevent cross-contamination of samples between cases. Additionally, bleach is used intentionally by criminals to clean up crime scenes and destroy DNA evidence. A previous study demonstrated that bleach has …
Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson
Veridical And False Memory Performance As A Function Of The Timing Of High-Intensity Acute Exercise, Claire Sanderson
Honors Theses
Background: Our recent experimental work demonstrated that high-intensity acute exercise improved veridical (true) memories and also increased the rate of false memories. The present experiment was designed to re-evaluate these effects for replication purposes. We also extend this literature by evaluating whether these effects are influenced by the timing of acute exercise. Methods: The sample included young adults (N=37; Mage = 21.16 years). We employed a three-condition, within-group, counterbalanced controlled design, consisting of two exercise conditions and a control condition. The exercise conditions involved a 15-minute bout of high-intensity acute exercise. These conditions included the bout of …
A Qualitative Analysis Of The Barriers Faced By Nursing Assistants And Medication Aides In The Care Of Dysphagia Residents, Lauren Kreuzberg
A Qualitative Analysis Of The Barriers Faced By Nursing Assistants And Medication Aides In The Care Of Dysphagia Residents, Lauren Kreuzberg
Honors Theses
Dysphagia refers to the symptom of difficulty in swallowing that accompanies several prevalent conditions in the older adult population, including amyotrophic lateral sclerosis (ALS, Lou Gehrig’s Disease), stroke, Parkinson’s Disease, Multiple Sclerosis, dementia, various cancers, and brain tumors (Allari, 2014). Many older adults who suffer from these conditions reside in nursing facilities, where most of their care is provided by certified nursing assistants (CNAs) and medication aides (MAs). However, the extent of these workers’ knowledge and competence in providing care to nursing home residents with dysphagia is vastly under-researched. The qualitative analysis investigates themes among interviews with fifteen CNAs and …
German Immigration And Its Ties To Landscape Change In Nebraska, Lindsey Labrie
German Immigration And Its Ties To Landscape Change In Nebraska, Lindsey Labrie
Honors Theses
This thesis uses a multidimensional approach to frame the different waves of German immigration within the context of land use change in Nebraska. By recounting the historical challenges and struggles Germans faced in their homelands, this thesis provides similarities between historical immigration patterns throughout the state. Observing the timing of these movements of people paints a clearer picture of how these immigrants might have helped change the farming and cultural landscapes of Nebraska. Knowing and recognizing historical immigration in Nebraska cultivates a deeper appreciation for the current relations between immigrants and Nebraska’s physical landscape.
Assessing A Two-Hit Model Of Schizophrenia: Prenatal Choline Deficiency And Induced Hypofunction Of Nmda Receptors In Male And Female Long Evans Rats, Samuel Gray, Samuel W. Gray
Assessing A Two-Hit Model Of Schizophrenia: Prenatal Choline Deficiency And Induced Hypofunction Of Nmda Receptors In Male And Female Long Evans Rats, Samuel Gray, Samuel W. Gray
Honors Theses
Choline is an essential dietary nutrient essential to the development and function of the central nervous system. Prenatal choline deficiency alters hippocampal development as well as acetylcholine metabolism, leading to cognitive impairments and attentional and sensory processing deficits into adulthood. MK-801 is an NMDA receptor antagonist frequently used in rodent models of neuropsychiatric conditions, particularly schizophrenia. Acutely and sub- chronically, it causes hyperlocomotion and social withdrawal. One primary goal of the present study were to investigate prenatal choline deficiency induces a biological vulnerability to the motor deficits, anhedonia, and social impairment precipitated by low-dose sub-chronic MK-801 administration in adulthood. Another …
Executive Function Deficit As A Precursor To Memory Impairments In Hapoe4 Transgenic Rats, Kaitlin Mcmanus
Executive Function Deficit As A Precursor To Memory Impairments In Hapoe4 Transgenic Rats, Kaitlin Mcmanus
Honors Theses
The hApoE4 allele is one of the strongest genetic risk factors for Alzheimer’s disease (AD). It underlies amyloid-bdeposits and neurofibrillary tangles, the two hallmarks associated with AD pathology, and is subsequently associated with AD symptomology. Despite its importance, no rat animal studies to date use hApoE4 knock-ins. In addition to this deficit in the field of AD literature, the vast majority of AD studies focus on memory, even though executive function deficits may precede memory impairments in AD, and may be a predictor of AD development. Thus, the present study addressed these gaps in AD research by investigating the behavioral …
