Larval Environments Affect The Implementation Of The Sterile Insect Technique On Aedes Mosquitoes, Katherine G. Evans
Larval Environments Affect The Implementation Of The Sterile Insect Technique On Aedes Mosquitoes, Katherine G. Evans
Theses and Dissertations
Sterile Insect Technique (SIT) is an effective method for controlling pests and has been increasing in popularity to control Aedes mosquitoes. SIT involves inundating an area with sterilized male mosquitoes to reduce egg hatch and ultimately the number of wild adults. Previous research indicates that enacting mortality early in the larval life of Aedes mosquitoes can result in counter-productive effects, due to reduced competition among developing larvae. I hypothesize that the effectiveness of SIT at reducing adult populations is modified by densitydependent mortality and density-dependent growth among larvae. I performed two field-to-lab studies and developed an individual-based model to test …

Associations Between Brain White Matter Hyperintensities And Diet Quality In Cognitive Aging: A Cross-Sectional Assessment, Carla V. Urdaneta
Honors Undergraduate Theses
Leukoaraiosis, or White Matter Lesions (WMLs)/White Matter Hyperintensities (WMHs), are often considered markers of aging and neurodegeneration. White matter hyperintensities appear as lighter, hyperintense regions on T2-weighted fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) scans and are physiologically characterized as demyelination and axonal loss reflected as microvascular lesions in cerebral white matter (Marseglia et. al., 2019). These anatomical landmarks are most seen in MRIs of elderly individuals. They can be associated with aging and cognitive decline, including affected frontal lobe function and episodic memory in the form of delayed recall performance and are linked to several cardiovascular risk factors, …
