The Apoptosis Regulator 14-3-3η and Its Potential as a Therapeutic Target in Pituitary Oncocytoma

open access: yesFrontiers in Endocrinology, 2019
The 14-3-3 protein family has attracted much attention in research into the pathogenesis of human tumors because of its involvement in tumorigenesis. In previous studies, we found that 14-3-3η was highly expressed in pituitary oncocytoma.

Axion minicluster power spectrum and mass function [PDF]

open access: yes, 2017
When Peccei-Quinn (PQ) symmetry breaking happens after inflation, the axion field takes random values in causally disconnected regions. This leads to fluctuations of order one in the axion energy density around the QCD epoch.

Renormalized spectrum of quasiparticle in limited number of states, strongly interacting with two-mode polarization phonons at T=0 K

open access: yesCondensed Matter Physics, 2021
Within unitary transformed Hamiltonian of Fröhlich type, using the Green's functions method, exact renormalized energy spectrum of quasiparticle strongly interacting with two-mode polarization phonons is obtained at T=0 K in a model of the system with ...

Synthesis and investigation of mass spectra of some novel benzimidazole derivatives

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2008
2-Substituted benzimidazoles (3) and (4a-c) were prepared via condensation of ethyl 2-thionyl-pyruvate (1) and hydrazidoyl derivatives (2a-c) with o-phenylene diamine in acetic acid.

Particle production in time-dependent gravitational fields: the expanding mass shell [PDF]

open access: yes, 2002
We compute the production of particles from the gravitational field of an expanding mass shell. Contrary to the situation of Hawking radiation and the production of cosmological perturbations during cosmological inflation, the example of an expanding ...

The intracellular domain of TLR2 is capable of high‐affinity Zn binding: possible outcomes for the receptor activation

open access: yesFEBS Letters, EarlyView.
Toll‐like receptors (TLRs) are important in the innate immune system. This study explores the zinc‐binding ability of the TLR2 TIR domain (TLR2TIR). We found that TLR2TIR binds zinc with nanomolar affinity through its cysteine residues. Two of them, C673 and C713, are vital for receptor activation, indicating that zinc may play a role in initiating ...

Ultra-High-Performance Liquid Chromatography–Electrospray Ionization–High-Resolution Mass Spectrometry for Distinguishing the Origin of Ellagic Acid Extracts: Pomegranate Peels or Gallnuts

open access: yesMolecules
Ellagic acid, known for its various biological activities, is widely used. Ellagic acid from pomegranate peels is safe for consumption, while that from gallnuts is only suitable for external use. However, there is currently no effective method to confirm
