FW: BME P-Card Standard Operating Procedure
by Rhonda Wolf Jones 25 Mar '25

25 Mar '25

Hello BME - I hope you had a great Spring Break! The updated Standard Operating Procedures (SOP) for Checking Out a Department P-Card have been finalized and is attached. This updated procedure reflects the latest best practices, regulatory requirements, and organizational improvements. Also attached are the Purchasing Card Policies Manual per Purdue Policies, a walkthrough guide of using Purdue's Service Portal ticketing system and a blank Purchase Request form Template. A quick reminder from the Manual "The Purdue University Purchasing Card (Pcard) provides an efficient, cost-efficient method of purchasing and paying for small dollar, non-repetitive transactions within established procurement guidelines, to conduct university business. Unless exceptions are listed in this document, all policies and procedures apply to all Purdue University locations. The Purchasing Card cannot be used to avoid or bypass appropriate procurement or payment procedures or for personal use." Please Refer to Page 12 of the Manual for "Appropriate Card Expenses" and a step by step on evaluating when to use Procurement services vs a P card. I encourage everyone to review the documents carefully to ensure familiarity with the updated processes. Key updates include: * Verify that your purchase should not go through Purdue Procurement instead of a P-Card * Cory Wilfong will be the designated Point of Contact * A completed purchase request form must be verified before you can check out a Card * Clear guidelines on submitting P-card receipts Please take the time to familiarize yourself with these changes. If you have any questions or need clarification, don't hesitate to reach out to Cory Wilfong or Dylon Chase." Thank you!

[Bmeroundtable-list] BME PhD Defense Announcement for Awadh Alhawwash (K. Yoshida, Chair)

BME PhD Defense Announcement for Awadh Alhawwash (K. Yoshida, Chair) Everyone is invited to attend the public presentation beginning at 10:30 AM. Title: Characterizing Peripheral Motor Nerve Activation Using Sinusoidal Low Frequency Alternating Currents Stimulation Date: Tuesday, April 1st, 2025 Time: 10:30 AM Location: Indianapolis campus, SL220A or Zoom - https://purdue-edu.zoom.us/j/91471372502?pwd=tsY7MKKXKHeQHHjuYh9F24pzPxhDRt…<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpurdue-ed…> Thesis Committee: Dr. Edward Berbari, Dr. Kevin Otto, Dr. Matthew Ward, and Dr. Ken Yoshida (Chair) Abstract: Peripheral nerve stimulation using implantable cuff electrodes and sinusoidal Low Frequency Alternating Currents (LFAC) is a novel approach being explored for neuromodulation. This dissertation has investigated the characteristics and mechanisms of motor nerve stimulation using LFAC across different stimulation paradigms. Our findings provide a foundational understanding of LFAC stimulation as a potential alternative to traditional pulsed stimulation in neuromodulation, specifically for vagus nerve stimulation and functional electrical stimulation applications. The first study showed the fundamental properties of LFAC stimulation using bipolar cuff electrodes, indicating the existence of inverse relationships between LFAC activation thresholds and both frequency and electrode pitch. The study provided the first evidence of orderly fibers recruitment with LFAC, both in-silico (utilizing volume conductor models and the McIntyre-Richardson-Grill, MRG, models of myelinated motor nerve fibers) and in acute in-vivo experiments (N = 34, isoflurane-anaesthetized rats). The results suggested that LFAC stimulation can maintain physiological recruitment patterns under certain conditions, and bipolar cuff electrode geometry influences nerve excitation thresholds. The second study investigated the underlying mechanisms of LFAC-induced activation through in-silico studies. The findings suggested a possible role of nerve membrane accommodation during LFAC stimulation and sodium channel dynamics in facilitating orderly recruitment with the influence of subthreshold oscillations. The study identified the fiber-frequency-dependent nature of LFAC activation and divergence from conventional pulse-based extracellular stimulation. The third study explored the influence of different cuff electrode configurations: unipolar, monopolar, bipolar, and tripolar on LFAC activation thresholds through in-silico studies. The results demonstrated that electrode geometry affects recruitment selectivity, activation efficiency, and threshold variability. Unipolar and monopolar configurations resulted in lower activation thresholds; however, their selectivity was reduced as frequency increased. On the other hand, bipolar and tripolar configurations provided more controlled activation as contact separation and cuff edge distance have interconnected influences. The findings suggest the importance of optimizing electrode design and/or configuration to maximize the advantage of LFAC stimulation. In the fourth study, an initial comparison of muscle fatigue induced by LFAC versus traditional rectangular pulse stimulation was conducted in-vivo (N = 3, isoflurane-anaesthetized rats). The preliminary results suggest that LFAC may increase fatigue resistance compared to pulsed stimulation, potentially offering advantages for mitigating FES rapid muscle fatigue and that LFAC frequency is a critical factor. Collectively, these studies established a foundation for sinusoidal LFAC motor nerve stimulation that could be optimized for targeted therapeutic and rehabilitative neuromodulation applications. -- Bmeroundtable-list mailing list Bmeroundtable-list(a)ecn.purdue.edu https://engineering.purdue.edu/ECN/mailman/listinfo/bmeroundtable-list

BME PhD Preliminary Exam Announcement for Elizabeth Frazier (M. Dadarlat, Chair) Everyone is invited to attend the public presentation beginning at 10:00 AM. Title: Using coherent motion perception to probe effects of traumatic brain injury on cortical physiology Date: March 31, 2025 Time: 10:00 AM Location: MRGN 129 or Zoom: https://purdue-edu.zoom.us/j/91715896410<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpurdue-ed…> Committee Members: Dr. Maria Dadarlat (chair) Dr. Anne Sereno Dr. Ed Bartlett Dr. Alex Chubykin Abstract: Traumatic brain injuries (TBIs) affect over 55 million individuals annually, with approximately 75% classified as mild (mTBI). mTBIs are characterized by an absence of overt structural brain damage detectable with conventional clinical imaging technologies. Despite this, up to 30% of mTBI cases lead to persistent visual dysfunction, including deficits in visual acuity, binocular coordination, spatial perception, and motion sensitivity. However, the neural mechanisms underlying these persistent visual deficits remain poorly characterized. Prior studies have reported elevated motion coherence detection thresholds following mTBI, suggesting a disruption in the cortical processing of global motion that correlates with prolonged recovery of normal visual function. I hypothesize that by correlating changes in visual perception with changes in neural dynamics after mTBI, we can use performance on a simple behavioral task to estimate less accessible measures of pathophysiological damage and injury prognosis. To test this hypothesis, I will first train mice to perform a perceptual decision-making task using a coherent motion stimulus while simultaneously recording population-level neural activity from the visual cortex with large field-of-view two-photon calcium imaging. This study will characterize the encoding of coherent motion information for reliable perceptual decision-making under normal sensory function (Aim 1). I will then administer a mTBI to perturb these neural dynamics and analyze how the resulting changes in neural activity map to deficits in coherent motion perception (Aim 2). Ultimately, this work will provide mechanistic insights into the cortical substrates of visual perceptual deficits following mTBI, informing the development of a behavioral biomarker to enhance diagnostic sensitivity and guide targeted rehabilitation strategies for individuals with persistent mTBI-related visual dysfunctions. -- Bmeroundtable-list mailing list Bmeroundtable-list(a)ecn.purdue.edu https://engineering.purdue.edu/ECN/mailman/listinfo/bmeroundtable-list
