Pharmacokinetics and Pharmacodynamics of a Single Oral Dose of Ascelia‐Manganese‐Based MRI Contrast Agent (ACE‐MBCA) in Adult Subjects With and Without Hepatic Impairment

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Orally administered Ascelia‐manganese‐based contrast agent (ACE‐MBCA) is used for liver MRI, but its feasibility in patients with hepatic dysfunction remains unknown. Purpose To investigate the pharmacokinetics (PK), pharmacodynamics, and safety of ACE‐MBCA in subjects without/with hepatic impairment.

Ultrasound‐assisted recirculation extraction as an innovative approach for obtaining bioactive compounds from grape pomace

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grape pomace, a by‐product generated during winemaking, still retains bioactive compounds with potential applications in the food, pharmaceutical and nutraceutical sectors. This work investigated ultrasound‐assisted extraction (UAE) coupled with a recirculation system as a strategy to improve their recovery.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Storage duration and water type determine the need for mercury chloride preservation of dissolved inorganic carbon

Limnology and Oceanography: Methods, EarlyView.
Abstract To quantify aquatic carbon budgets, it is important to accurately measure dissolved inorganic carbon (DIC). The standard approach requires the use of mercury chloride (HgCl2) poison to preserve samples, but the real need and overall constraints of using such a toxic compound remain elusive. Here, we evaluate the need for filtration and mercury
