Defensive functions and potential ecological conflicts of floral stickiness

Scientific Reports, 2022
Stickiness of vegetative tissues has evolved multiple times in different plant families but is rare and understudied in flowers. While stickiness in general is thought to function primarily as a defense against herbivores, it may compromise mutualistic ...

Native mass spectrometry-A valuable tool in structural biology.

Journal of Mass Spectrometry, 2020
Proteins and the complexes they form with their ligands are the players of cellular action. Their function is directly linked with their structure making the structural analysis of protein-ligand complexes essential.

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

A cosmogenic 10Be anomaly during the late Miocene as independent time marker for marine archives

Nature Communications
Cosmogenic nuclide dating relies on the constancy of production and incorporation of radionuclides in geological archives. Anomalous deviations from constancy during the Holocene or Pleistocene are frequently used as global benchmarks to harmonize ...

Mass spectrometry and fullerenes [PDF]

Journal of the American Society for Mass Spectrometry, 1992
This article presents, from amass spectrometry perspective, an historical account of research on gas-phase carbon clusters, which has led to the discovery of another form of carbon, fullerenes. In addition, more recent mass spectrometric studies on analysis of fullerene derivatives and synthesis of doped fullerenes are described.
