Tannic Acid-Stabilized Liposomal Platform For Microrna Delivery In Endometriosis, Victoria Herrera, Rahul Tiwari, Bridgette Lozano Lozano, Subhash Chauhan, Murali Yallapu

Research Symposium

Background: Endometriosis is defined as the presence of endometrial-type mucosa outside the uterine cavity. It affects about 6.5 million women of reproductive age in the United States. It is a leading cause of infertility, impacting up to 50% of women with difficulty conceiving, and is prevalent in as many as 90% of individuals experiencing severe, chronic pelvic pain. Women with endometriosis had 4.2-fold higher ovarian cancer risk than those without endometriosis. Within this work, a range of liposomal formulations was investigated for endometriosis. Recent studies confirmed the role of miR-205-5p as a potential suppressor of ectopic endometriotic progression. Clinical translation …

Electrochemical Detection Of Dopamine Using Screen-Printed Graphene Electrode For Cancer Diagnosis And Therapy, Pritu P. Sarkar, Nazmul Islam

Research Symposium

Background: Dopamine plays a critical role in various essential functions, including motor control, hormone regulation, cognition, learning, and the reward system. In healthy individuals, dopamine levels are extremely low, with concentrations ranging from 0 to 0.25 nM in blood and 0.3 to 3.13 µM in urine. Abnormal levels are linked to disorders like Parkinson’s, schizophrenia, Alzheimer’s, epilepsy, hypertension, and arrhythmia. Abnormal dopamine levels can indicate the presence of certain cancers. Dopamine receptors may be therapeutic targets for treating cancer, especially breast and colon cancer. Thus dopamine can increase the efficacy of anticancer drugs in breast and colon cancer. Detecting dopamine …

Effect Of Walking Speed And Asymmetric Loading On Human Gait, Dumitru I. Caruntu, Alfirio Trejo, Eric Rodriguez, Camila T. Alvarez Barriga

Research Symposium

Background: Human gait is influenced by factors such as walking speed and carrying heavy objects asymmetrically. Understanding these effects enhances rehabilitation research for individuals recovering from leg injuries. Clinical angles of the knee, derived from experimental data, provide insights into movement patterns, revealing abnormalities or compensations. Calculating these angles requires a joint coordinate system (JCS) for the knee joint.

Methods: This study employed the VICON motion analysis system with ten infrared cameras arranged circularly for comprehensive gait analysis. Reflective markers placed on anatomical landmarks facilitated motion capture, recorded at 100 Hz. Data processing included filtering, establishing a JCS, …

Muscle Force Analysis In Patients With Forefoot Amputees And Healthy Subjects During Walking, Anthony Melgar, Dumitru Caruntu, Javier La Fontaine, Luis Venegas, Hafizur Rahman

Research Symposium

Forefoot amputation, a type of partial foot amputation, involves the surgical disarticulation of either the interphalangeal or metatarsophalangeal joints. This procedure not only removes critical joint structures but also alters the positioning of associated muscles. Forefoot amputations significantly affect gait patterns and redistribute plantar pressure maps across the plantar surface of the foot. The phalanges are crucial in absorbing and redistributing plantar pressure during the gait cycle. The absence of phalanges and the loss of metatarsophalangeal joints alter the normal pressure distribution maps, possibly shifting peak pressure from one local foot region to another region of the foot. This research …

Increasing Guard Band Size To Decrease Interference In V2x Communication, Nakira Oglesby, Mackenzie Prescott, Billy Kihei, Ph.D.

Symposium of Student Scholars

As technologies evolve and new devices are introduced, the demand for fast and reliable vehicle-to-everything (V2X) communication increases. As this demand increases, the interference level in the 5.9GHz Dedicated Short Range Communications (DSRC) band will inevitably increase. And thus, the task of somehow minimizing this interference becomes increasingly important as time passes. This report investigates the effects of increasing the guard band size of the lower 5.9 GHz DSRC band on the adjacent channel interference from Unlicensed National Information Infrastructure 4 band (U-NII-4) devices and to try and see if there is a significant decrease in the interference level. The …
