Robotic Interventional Needle Insertion Assisted by a Cable‐Driven Parallel Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents a body‐mounted cable‐driven parallel robot assisting the needle insertion procedure designated for automated interventional pain therapy. The 3D‐printed robot body and multiple thin cables can achieve high X‐ray compatibility for intervention. The robot performs full 6‐degree of freedom needle insertion and remote center of motion

Cerebral Small Vessel Disease in Older Adults With Olfactory Dysfunction

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Poor vascular health has been associated with age‐related declines in sensory functions, including olfaction. The current study was designed to test the hypothesis that cerebral small vessel disease underlies poor olfactory function due to structural declines in brain regions that support olfaction.

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.
