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

open access: yesGreen 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.

Single-Molecule Detection of Nucleic Acids via Liposome Signal Amplification in Mass Spectrometry

open access: yesSensors, 2022
A single-molecule detection method was developed for nucleic acids based on mass spectrometry counting single liposome particles. Before the appearance of symptoms, a negligible amount of nucleic acids and biomarkers for the clinical diagnosis of the ...

Mass spectrum of elementary particles [PDF]

open access: yesE3S 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.

Quantitative Ubiquitinomics Revealed Abnormal Ubiquitinated ATP7A Involved in Down-Regulation of ACTH in Silent Corticotroph Adenomas

open access: yesFrontiers in Endocrinology, 2022
Ubiquitination is reported to be a critical biological event on ACTH secretion in corticotroph adenomas. However, the effect of ubiquitylation on ACTH secretion in silent corticotroph adenomas (SCAs) remains unclear.

The mass spectrum of interstellar clouds [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
AbstractThe abundance of 21-cm absorption lines seen in surveys at high latitudes can be translated into a line of sight abundance of clouds vs. column density using an empirical relationship between temperature and optical depth. As VLA surveys of 21-cm absorption at low latitudes are now becoming available, it is possible to study the variation of ...

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

open access: yesClinical 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

Methane Cluster Fragmentation by Fast Electron Impact

open access: yesAtoms, 2023
We investigate the fragmentation of the CH4 cluster by fast electron impact at stagnation pressures from 0.5 bar to 16 bar. By measuring the time of flight spectrum (TOF), two types of ions, including (CH4)n−1CH5+ and (CH4)n−2(C2Hm)+, are observed.

A MASS SPECTRUM FOR LEPTONS AND QUARKS [PDF]

open access: yesModern Physics Letters A, 1993
A suggestive phenomenological relation is found among the lepton and quark masses which suggests a new insight into the problem of generations and also gives a prediction for the top quark mass in agreement with the range of values which is actually expected.
