Study on titanium dioxide nanoparticles as MALDI MS matrix for the determination of lipids in the brain

Green Processing and Synthesis, 2021
The structures of lipids are diverse, and thus, lipids show various biological functions. Systematic determination of lipids in organisms has always been a concern.

Mass spectrum of elementary particles [PDF]

E3S Web of Conferences, 2023
In this study, we discuss different methods for quantifying the mass of elementary particles. The Barut’s model approach gives us a more comprehensive understanding of elementary particles and their formation through magnetic interaction.

Dracorhodin targeting CMPK2 attenuates inflammation: A novel approach to sepsis therapy

Clinical and Translational Medicine, 2023
Background Despite all modern advances in medicine, an effective drug for treating sepsis has yet to be found. The discovery of CMPK2 spurred hopes for the treatment of sepsis. However, CMPK2‐untapped target inhibitors are still an enormous obstacle that

Charm mass corrections to the bottomonium mass spectrum [PDF]

, 2002
The one-loop corrections to the bottomonium mass spectrum due to the finite charm mass are evaluated in the framework of the relativistic quark model. The obtained corrections are compared with the results of perturbative QCD.Comment: 6 pages, references

Baryon Mass Spectrum [PDF]

Progress of Theoretical Physics, 1958
The possibility has been pointed out that if the relative parity between nucleons and particles is assumed to be odd, the lowest order self-energies of baryons coming from the charge-independent strong interaction give the observed baryon mass level ordering. Schwinger also suggested such a level splitting in a discussion of the isospace symmetry.
