Mechanical Coupling With the Nuclear Envelope Shapes the Schizosaccharomyces pombe Mitotic Spindle

Cytoskeleton, EarlyView.
ABSTRACT The fission yeast Schizosaccharomyces pombe divides via closed mitosis, meaning that spindle elongation and chromosome segregation transpire entirely within the closed nuclear envelope. Both the spindle and nuclear envelope must undergo shape changes and exert varying forces on each other during this process.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

A Short Peptide Inhibitor of Measles Virus Fusion Protein that Exhibits Passive Membrane Permeability

ChemMedChem, EarlyView.
Fusion inhibitor peptide (FIP) is a known small peptide capable of inhibiting measles virus infection. In this study, hydrogen‐to‐fluorine substitution is employed to derivatize FIP, leading to the discovery of a FIP derivative with enhanced inhibitory activity and passive membrane permeability.

The Electronic Spin State of Diradicals Obtained from the Nuclear Perspective: The Strange Case of Chichibabin Radicals

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The electronic spin state of two Chichibabin radicals is investigated using 2‐dimensional hyperfine correlated Electron Nuclear Double Resonance. The protons (I=1/2) act as a reference for the electronic spin quantum number (S) via their hyperfine interactions.

Evidence for Anion‐Anion Interaction in Amino Acid Ionic Liquids Probed by Far‐Infrared Spectroscopy

ChemPhysChem, EarlyView.
Spectroscopic evidence for doubly hydrogen bonded anionic dimers in amino acid ionic liquids is provided. The torsional motion of the amine groups is characteristic for cation‐anion and anion‐anion interaction as observed in far‐infrared spectra. Herein, it is shown that far‐infrared spectroscopy is a sensitive probe for detecting not only cation‐anion
