Die Anwendung radiochemischer Analysenmethoden zur Bestimmung von Zink- und Calciumspuren in Gallium
CHIMIA, 1961 The method ot thermal neutron activation analysis has been utilized for the determination of calcium and zinc traces in metallic gallium. This method allows to measure amounts of calcium as low as one p.p.m.

Advanced Science, EarlyView.Higher plasma leucine is associated with increased risk of new‐onset myocardial infarction. Leucine deprivation alleviates advanced atherosclerosis in mice. Tumor‐induced leucine deprivation reprograms macrophage metabolism and increases CD5Lhi macrophages in mouse plaques. Mechanistically, leucine deficiency reduced SLC7A5‐PGAM5 binding in macrophages,

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection
Angewandte Chemie, EarlyView.In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...

South Asian monsoon history over the past 60 kyr recorded by radiogenic isotopes and clay mineral assemblages in the Andaman Sea [PDF]
, 2015 The Late Quaternary variability of the South Asian (or Indian) monsoon has been linked with glacial‐interglacial and millennial scale climatic changes but past rainfall intensity in the river catchments draining into the Andaman Sea remains poorly ...

Advanced Science, EarlyView.Radiation induces polyploid giant cancer cells (PGCCs) that regenerate tumors through virus‐like budding. This process depends on a SNCG–FLOT2–CHMP4B signaling axis functioning in lipid raft microdomains. Disrupting these domains using statins or anti‐PCSK9 antibodies blocks PGCC budding, suppresses tumor repopulation, and enhances radiotherapy ...
