Discovery of the Cyclic Form of MRI pH‐Sensor Z‐OMPD Enables >5% 13C Hyperpolarization by SABRE

Angewandte Chemie International Edition, EarlyView.
With “c‐OMPD”, we discovered a previously unknown 5‐membered lactol structure that arises from the homoaldol condensation of the central metabolite pyruvic acid. We demonstrate that the cyclization equilibrium is of crucial importance for OMPD's function as MRI‐based pH sensor and achieve for the first time 13C polarization levels (>5%) by SABRE in the

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

The Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

The Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Improvement in Patient‐Reported Outcomes, High Rate of Return to Sport, and Secondary Surgery Rate Ranging From 0% to 9.8% After Hip Arthroscopy in Dancers and Athletes in Flexibility Sports: A Systematic Review

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To systematically review and report patient‐reported outcome measures (PROMs), rates of return to sport, and secondary surgeries in dancers and flexibility sport athletes who underwent hip arthroscopy. Methods Using the 2020 Preferred Reporting Items for Systematic Reviews and Meta‐Analyses criteria, a systematic review was performed with a ...
