The regulation of stem cell fate and its application in neural regeneration

Interdisciplinary Medicine, EarlyView.
Regulating stem cell fate is crucial for neural regeneration. This review summarizes key physical, biological, and chemical strategies and their applications in repairing nerve injuries, providing new insights for regenerative medicine. Abstract Regulating the fate of stem cells (SCs) is a key technical problem in the field of regenerative medicine and

Synthesis, Cytotoxicity, and Apoptosis‐Associated Cell Death Activity of an Isatin‐Containing Pyrimidine‐Derived Cu(II) Complex

Journal of Applied Toxicology, EarlyView.
ABSTRACT A Cu(II) complex derived from a pyrimidine with the isatin group was synthesized and tested for its cytotoxic effects on A549 lung cancer and MCF‐7 breast cancer cell lines, as well as its effects on apoptosis‐associated cell death and cell cycle regulation in A549 cells. To evaluate cytotoxicity, MTT assays were performed at 24, 48, and 72 h,

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities

Laser &Photonics Reviews, EarlyView.
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.
