Prebiotic Investigations and Reaction Network Analysis on the Wöhler‐RNA System

ChemSystemsChem, EarlyView.
The prebiotic reaction toward the Wöhler‐RNA, a Proto‐RNA‐candidate, using aldehydes and biuret or triuret results in a mixture of the α‐ and β‐ furanosides and pyranosides. Investigation of the interconversion of these isomers shows different reactivity and stability of the biuret and triuret analogues as well as between the corresponding furanosides ...

Recent Synthetic Advances in C–H/N–H Functionalization of 1H‐Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds

The Chemical Record, EarlyView.
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Differences in the Fecal Metabolome of Autoimmune Pancreatitis Patients

United European Gastroenterology Journal, EarlyView.
ABSTRACT Background Chronic pancreatitis is a risk factor for pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis that is primarily characterized by its immune mediate etiology, clinically resembling pancreatic cancer, yet uniquely responsive to steroid treatment.

Pay up or die: Tradeoffs between costly telomere maintenance, somatic growth and body condition in embryonic and adult sand lizards

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Current knowledge about telomere biology relies to a very high degree on results from research on endotherms. This would not be problematic if organisms shared the same mechanisms regulating telomere length (TL) but this is not necessarily the case; for example, most ...
