Repeated Acoustic Vaporization of Perfluorohexane Nanodroplets for Contrast-Enhanced Ultrasound Imaging [PDF]
arXiv, 2021 Superheated perfluorocarbon nanodroplets are emerging ultrasound imaging contrast agents boasting biocompatible components, unique phase-change dynamics, and therapeutic loading capabilities. Upon exposure to a sufficiently high intensity pulse of acoustic energy, the nanodroplet perfluorocarbon core undergoes a liquid-to-gas phase change and becomes ...

Multiplex ultrasound imaging of perfluorocarbon nanodroplets enabled by decomposition of post-vaporization dynamics [PDF]
arXiv, 2023 Among the various molecular imaging modalities, ultrasound imaging benefits from its real-time, nonionizing, and cost-effective nature. Despite its benefits, there is a dearth of methods to visualize two or more populations of contrast agents simultaneously, a technique known as multiplex imaging.

Compressed Sensing with Signal Averaging for Improved Sensitivity and Motion Artifact Reduction in Fluorine-19 MRI [PDF]
NMR Biomed (2019), e4418, 2019 Fluorine-19 (19F) MRI of injected perfluorocarbon emulsions (PFCs) allows for the non-invasive quantification of inflammation and cell tracking, but suffers from a low signal-to-noise ratio and extended scan time. To address this limitation, we tested the hypothesis that a 19F MRI pulse sequence that combines a specific undersampling regime with signal

Coating-free Underwater Breathing via Biomimicry [PDF]
arXiv, 2023 Numerous natural and engineering scenarios necessitate entrapment of air pockets or bubbles on submerged surfaces, e.g., aquatic insects, smartphones, and membranes for separation and purification. Current technologies for bubble entrapment rely heavily on perfluorocarbon coatings, which limits their sustainability and applications.

Monitoring and Control System Development and Experimental Validation for a Novel Extrapulmonary Respiratory Support Setup [PDF]
arXiv, 2021 This paper presents a novel mechatronic setup intended for providing respiratory support to patients suffering from pulmonary failure. The setup relies upon the circulation of an oxygenated perfluorocarbon (PFC) through the abdominal cavity. Such circulation provides a potential pathway for the transport of oxygen to the bloodstream.

Circadian modulation of microglial physiological processes and immune responses
Glia, Volume 71, Issue 2, Page 155-167, February 2023., 2023 Main Points Microglia are rhythmic cells with an oscillatory expression in clock genes, cytokines, and other microglial markers. Microglial circadian rhythms determine their physiological function and immune responses. Abstract Microglia is considered the central nervous system (CNS) resident macrophages that establish an innate immune response against
