Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Electronic Structure of 1,3-dicarbomethoxy4,6-benzenedicarboxylic acid: Density Functional Approach
International Journal of Electrochemical Science, 2013 Structural optimization of 1,3-dicarbomethoxy4,6-benzenedicarboxylic acid single crystal was performed by minimizing the forces which act on the atoms. The optimized geometry was used to perform the theoretical study of electronic properties, electronic ...

The Stokes Phenomenon and Quantum Tunneling for de Sitter Radiation in Nonstationary Coordinates
, 2010 We study quantum tunneling for the de Sitter radiation in the planar coordinates and global coordinates, which are nonstationary coordinates and describe the expanding geometry. Using the phase-integral approximation for the Hamilton-Jacobi action in the

International Journal of Optics, 2018 Under the scalar paraxial approximation, an optical wavefield is considered to be complex function dependent on position; i.e., at a given location in space the optical field is a complex value with an intensity and phase.

Molecular Oncology, EarlyView.A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

New Bernstein type inequalities for polynomials on ellipses [PDF]
New and sharp estimates are derived for the growth in the complex plane of polynomials known to have a curved majorant on a given ellipse. These so-called Bernstein type inequalities are closely connected with certain constrained Chebyshev approximation ...
