Thermal Dose Inactivation Of Escherichia Coli By Magnetic Induced Hyperthermia, Silverio A. Lopez, Carlos Trevino De Leo, Ivan Davila, Karen S. Martirosyan

Research Symposium

Background: Apoptosis of mutated cells via magnetic hyperthermia has gained advocacy as technology capable of being used in lieu of chemotherapy for targeting cancer tumors. Progress of nanotechnology offers effective remote heating of magnetic fluid via hyperthermia. The heating and specific power absorption of these nanoparticles use in the magnetic fluid are dependent on particle properties and treatment locations.

Methods: Nanoparticles were fabricated using microfluidic system by interaction of two solutions containing 2Fe(NO3)3+FeSO4 and NaOH+2%Dextran to create nanostructured media with a biocompatible dextran coating and a Fe3O4 core. The nanoparticles, of a concentration of 5mg/ml, were placed in a vile …

Racial Differences In The Effect Of Apoe-Ε4 Genotypes On Trail Making Test Part B In Alzheimer’S Disease, Kaysie N. Ozuna, Annu Katithara, Chun Xu

Research Symposium

The trail making test part B (TMT-B) is used to evaluate executive functions in order to better understand the progression of Alzheimer’s disease (AD). The objective of this study is to better understand the association of apolipoprotein E epsilon 4 (APOE-ε4) genotypes on the TMT-B scores in those with Alzheimer’s disease, specifically in the Hispanic population. This study used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI). In total there were 482 participants with AD, 503 with cognitive normal (CN), 1,293 with MCI at baseline and a follow-up after four years. In this study the longitudinal effect of …

Using Cartesian Coordinate Systems To Create, Classify, And Retrieve Biomedical Time-Series: Applications To 24-Hour Ambulatory Blood Pressure Monitoring, Antonio Garcia, Gladys E. Maestre, John Blangero, Jesus D. Melgarejo, Julio Facelli

Research Symposium

Background: Ambulatory Blood Pressure Measurement (ABPM) allows physicians to monitor blood pressure variability under everyday living conditions and predicts clinical outcomes better than conventional blood-pressure measurement. ABPM can demonstrate mean arterial pressure (MAP) behavior over 24 hours relevant to clinical practice, such as nocturnal hypertension or increased blood pressure variability. We hypothesized that individuals with the same cardiovascular health status would have the same MAP signal (MAPs) waveform.

Methods: This study reutilizes a data subset from the IDACO Consortium to create 24-hour MAPs. We assigned all the MAPs to data matrix X, performed principal components analysis (PCA) to X, and …
