A Consumer Ultrasound for Autonomous Heart Attack Detection

A Consumer Ultrasound for Autonomous Heart Attack Detection Pradyuman Mittal Tara Nash Patrick Murphy Stanford University  Abstract Every year, half of the 610,000 heart attack deaths in the United States are due to a lack of prompt medical attention. Currently, most technologies fail to fix the problem, as they simply take too long to be able to detect a heart attack in time. Either the biomarkers they track spike in delayed reactions or the device is not capable […]

Unraveling Alzheimer's: The Effects of Tau on AB Protein Aggregation

Abstract Alzheimer’s is a neurodegenerative disease characterized by the formation of extracellular amyloid-beta (abeta or AB) plaques and intracellular tau plaques. This experiment explores whether the presence of normal tau-441 protein augments AB-42 aggregation. The concentration at which each protein self-aggregated was identified by creating aggregation curves. A control and experimental aliquot of AB/buffer and AB/tau respectively were then scanned at regular intervals to determine the rate amount of aggregation in each. The conclusion is […]

Examining the Effect of TRIP13 Over Expression on Cancerous Aneuploidy

        This Research was completed with the University of Toledo Sanjay Jinka Anthony Wayne High School 2801 W Bancroft St, Toledo, OH 43606 ABSTRACT Nineteen million people are projected to have cancer by 2024 so understanding tumorigenesis is of foremost importance. Of solid tumors, 90 percent are aneuploid, signifying an abnormal number of chromosomes usually caused by malfunctioning mitotic checkpoints. TRIP13 AAA-ATPase is a crucial silencing protein in this checkpoint. Therefore, it was hypothesized that TRIP13 […]
