SUMMARY:Investigating Plant Terpenoid Metabolism and Bioproduct Applications
DESCRIPTION:Prof. Philipp Zerbe\, UC Davis\nSponsored by California ACS Local Section\n11:30 am-2:00 pm\, Hybrid Event: In-person $20 for lunch reservation ($10 students) at North Berkeley Senior Center\, 1901 Hearst Ave\, Berkeley. Online free\, Learn more and register | Download flyer\n\n“Join us on Sunday\, January 19\, 2025 for a buffet lunch\, networking\, and a chance to explore the exotic chemistry of plants.  Professor Philipp Zerbe will present new results from his laboratory at UC Davis\, including their studies of the scent compounds from the Wollemi Pine (shown above).  This ancient species dates to the era of the dinosaurs\, and was thought to be extinct until its discovery in the remote mountains of New South Wales\, Australia in 1994.  Its survival in the wild is threatened\, and the UCB Botanical Garden is one of many centers working to preserve the species.  Professor Zerbe is working with researchers at the Botanical Garden to study the unique chemistry of this mysterious plant. \nLunch Reservations (12:00 PM) – Please Click Here\nIf you can’t join us in-person\, you can still join us online! \nRegister for the Zoom Meeting at 1:00 PM – Click Here\nWe look forward to seeing you on January 19th! \nDownload the event flier HERE. \nAbstract\nPlants are nature’s master chemists; they deploy complex networks of specialized metabolites to interact with other organisms and adapt to their environment. Among these metabolites\, terpenoids encompass the largest class with critical functions in plant development\, chemical ecology and stress adaptation. Terpenoid chemical diversity also offers a rich source for bioproducts\, including flavors\, fragrances\, pharmaceuticals and more. A deeper understanding of the mechanisms underlying the diversity of plant terpenoid metabolism can offer innovative avenues toward agricultural and other industrial applications. Toward this vision\, the Zerbe Lab integrates functional genomics\, metabolomics and various protein biochemical and genetic appraoches to investigate the biosynthesis and physiological function of terpenoids in food\, bioenergy\, and medicinal plants. We will discuss the discovery of common and species-specific terpenoid pathways across different plant species that provide new insights into the evolutionary divergence of terpenoid metabolism\, its role in plant-environment interactions\, and how this knowledge can be applied toward crop improvement and bioproduct engineering. \nAbout the Speaker\nPhilipp Zerbe is a Professor at the Department of Plant Biology\, University of California at Davis. His research group focuses on the discovery and engineering of specialized terpenoid metabolism in food\, bioenergy and medicinal plants. For his research\, Dr. Zerbe received the 2015 Arthur Neish Young Investigator Award\, a 2016/17 Hellman Fellowship\, and 2018 Elsevier Young Investigator Award. Prior to his position at UC Davis\, Dr. Zerbe received his PhD from the Ruhr-University Bochum\, Germany (2007) with emphasis on structure-function studies plant hormone metabolism\, followed by positions as a Postdoctoral Fellow and Research Associate at the University of British Columbia (Vancouver\, Canada) where he focused his research on the discovery of terpenoid metabolism with relevance for bioproducts and stress tolerance in food crops and forest trees.”

SUMMARY:Wearables for Health: Smart Bandage and Hydration Sensing
DESCRIPTION:Yuanwen Jiang\, Ph.D.\, Postdoctoral Scholar\, Chemical Engineering\, Stanford University; and Michelle Hoogenhout\, Ph.D.\, Lead Data Scientist\, Hydrostasis\nSponsored by Stanford Wearable Electronics Initiative\n12:15-1:15pm\, Online and in person (Y2E2 Building\, Rm. 299)\, Free\, Registration required\n\nEvent Details:\n\n“Wireless smart bandage for chronic wound management and accelerated tissue regeneration”\nSpeaker: Yuanwen Jiang\, Ph.D.\, Postdoctoral Scholar\, Chemical Engineering\, Stanford University\nAbstract: Chronic non-healing wounds represent a major source of morbidity for patients and a significant economic burden. Current wound care treatments are generally passive and are unable to adapt to changes in the wound environment in real time. By integrating multimodal sensors and adding stimulators in a bandage\, real-time physiological monitoring is possible and provides an opportunity for active intervention into the complex wound environment. Here\, we develop a battery-free flexible bioelectronic system consisting of wirelessly powered\, closed-loop sensing and stimulation circuits with tissue-interfacing tough conducting hydrogel electrodes for robust signal transduction\, on-demand adhesion\, and detachment. Using multiple pre-clinical models\, we demonstrate the capability of our wound care system to continuously monitor skin impedance and temperature\, to trigger directional electrical stimulation. The accelerated wound closure was confirmed to be due to the activation of pro-regenerative genes linked to accelerated wound closure\, increased neovascularization\, and enhanced dermal recovery. \n“Personalized and reliable hydration detection using a wrist-based photoplethysmography (PPG) sensor”\nSpeaker: Michelle Hoogenhout\, Ph.D.\, Lead Data Scientist\, Hydrostasis\nAbstract: Proper hydration and fluid management is challenging\, particularly in the elderly and those with heart and kidney failure. The consequences of improper hydration are costly: Dehydration-related conditions accounted for nearly $5.5 billion in hospital charges\, according to the 2004 US National Hospital Discharge Survey. Even minimal dehydration\, classified as 1-2% loss in total body water\, affects physical performance\, mood and cognition. Hydration monitoring is therefore also important in professional sport and combat training\, where water loss exceeding 2% of total body weight is common. However\, because there are currently no reliable\, non-invasive instruments to continuously monitor hydration status\, consumers and clinicians have to rely on monitoring weight\, checking physical signs of dehydration\, or taking urine or saliva samples. \nThe Hydrostasis GecaTM optical wristband monitors tissue hydration levels and provides real-time feedback to users on their hydration status. The wristband uses photoplethysmography (PPG) to detect changes in hemoglobin\, lipids and water volume in the tissues. In a pilot study with 54 healthy adults\, we found significant differences in water-related PPG signals between non-hydration\, hydration and exercise-induced dehydration conditions. Using a binary hydration/non-hydration classifier\, we could predict hydration state in new users with 67% precision and 78% recall\, and could predict optimal hydration with 72% precision and 96% recall. These results hold promise for continuous\, remote monitoring of hydration status. The sensor can be used in a stand-alone device or integrated into existing smartwatches using PPG. \nFor bios please visit ewear.stanford.edu \nVisit this website for more information
