Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

open access: yesAdvanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Radioactivity in returned lunar materials [PDF]

open access: yes
The H-3, Ar-37, and Ar-39 radioactivities were measured at several depths in the large documented lunar rocks 14321 and 15555. The comparison of the Ar-37 activities from similar locations in rocks 12002, 14321, and 15555 gives direct measures of the ...

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

open access: yesAngewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

Embedding Chemistry and Pharmacy Into Sustainability

open access: yesAngewandte Chemie International Edition, EarlyView.
Chemistry and pharmacy provide products and processes that are indispensable for our high living standard. To understand their relationship with sustainability is important to allow them to contribute to sustainability in a sustainable manner. An integrated overview of green, circular, and sustainable chemistry and pharmacy is given and how they have t

Forcing the Side‐on π‐Coordination of a C≡C Triple Bond to Technetium Using the As,CC,As Alkyne Pincer Ligand 1,2‐Bis(2‐(diisopropylarsaneyl)‐4‐(trifluoromethyl)phenyl)Ethyne

open access: yesAngewandte Chemie International Edition, EarlyView.
Technetium alkyne complexes have eluded isolation for decades with the only indicators for their existence being the isolation of vinylidene carbenes or their follow‐up reaction products despite plentiful of reports for neighboring elements. Stable, crystalline Tc(III) and Tc(V) alkyne complexes (and their Re analogs) have now been prepared and fully ...

Experimental Evidence for a Metal‐Related Function of a Cyanobactin

open access: yesAngewandte Chemie International Edition, EarlyView.
Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.
