Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

In Situ XOR Encryption for Lightweight Security Using Nanoelectromechanical Physically Unclonable Functions

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel in situ XOR encryption/decryption method using a nanoelectromechanical physically unclonable function (NEM‐PUF) is introduced, enhancing security in data transfers between servers/clouds and edge devices. Integrated with the CMOS BEOL process, NEM‐PUFs utilize random stiction for entropy, enabling efficient bitwise XOR operations. This approach

Substance Use Right Before or During Work Among the Young US Workers: Evidence From the National Longitudinal Survey of Youth 1997 Cohort

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Objective Substance use right before or during work (hereinafter, “substance use in the workplace”) poses significant health risks to users, colleagues, and the public in the workplace. However, less clear are figures on recent prevalence, characteristics of those engaging in such behaviors, and variations across occupations.

Production Of 11C‐Labeled Amides Via “In‐Loop” 11C‐Carbonylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The current work utilizes carbon‐11 labelled aroyl dimethylaminopyridinium salts in a two‐step in‐loop carbonylative cross‐coupling reaction of aryl halides with [¹¹C]CO yielding a diverse range of carbon‐11 labelled primary benzamides with good to excellent yields.

Enantiomerically Enriched Aziridine‐2‐carboxylates via Copper‐Catalyzed Reductive Kinetic Resolution of 2H‐Azirines

open access: yesAngewandte Chemie, EarlyView.
Kinetic resolution by copper hydride catalyzed reduction of 2H‐azirines secured optically enriched N‐H aziridine‐2‐carboxylates with excellent diastereoselectivity (>20:1) and good enantioselectivity (up to 94% ee). DFT calculations and non‐covalent interaction analysis established the reaction pathway and revealed two key non‐covalent interactions ...

Effects of Dictyophora polysaccharide on cerebellar Purkinje cell degeneration in a chronic alcohol mouse model

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In an ethanol (EtOH)‐treated mouse model, increases in the NLRP3 inflammasome proteins, PC degeneration, and motor coordination disorders were observed. DIP suppressed the NLRP3‐ASC‐caspase‐1 signaling pathway, and alleviated the motor deficits and cerebellar pathological changes in chronic EtOH‐treated mice.

Oxidative Rearrangements of the Alkaloid Intermediate Geissoschizine

open access: yesAngewandte Chemie, EarlyView.
19E‐geissoschizine is a key precursor in the biosynthesis of monoterpene indole alkaloids such as strychnine, ibogaine, and vinblastine. Using enzymatic assays and gene silencing, three CYPs were identified from C. roseus that oxidize this compound to four alkaloid scaffolds: strychnos, sarpagan, akuammiline, and mavacurane. Mutational analysis reveals
