A Comment on Heavy Quark Effective Fields [PDF]

open access: yesNuovo Cim. A110 (1997) 295-302, 1996
Effective fields defined in the heavy-quark effective theory to describe heavy quarks in heavy-light hadrons are examined in some detail in the standard formulation of a quantum field theory.

Positive feedback loop between MAPK and aquaporin 7 regulates autophagy and apoptosis induced by palmitate in RIN‐m5f cells

open access: yesFEBS Open Bio, EarlyView.
T2DM is characterized by peripheral blood insulin resistance and progressive pancreatic β‐cell dysfunction. Here, we showed that AQP7, the only aquaglyceroporin protein, regulates autophagy and apoptosis in pancreatic β‐cells. We propose the existence of a positive feedback loop between MAPK signaling and AQP7 that regulates autophagy and apoptosis in ...

Nucleon-Nucleon effective field theory with dibaryon fields [PDF]

open access: yesarXiv, 2009
We report on a calculation of the nucleon-nucleon scattering amplitudes in the $^1S_0$ and $^3S_1$-$^3D_1$ channels at next-to-next to leading order using a recently proposed non-relativistic chiral effective theory, which includes dibaryon field as fundamental degrees of freedom.

Establishment and biological characterization of radioresistant colorectal cancer cell lines

open access: yesFEBS Open Bio, EarlyView.
Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

Superconducting multi-vortices and a novel BPS bound in chiral perturbation theory

open access: yesJournal of High Energy Physics
We derive a novel BPS bound from chiral perturbation theory minimally coupled to electrodynamics at finite isospin chemical potential. At a critical value of the isospin chemical potential, a system of three first-order differential field equations ...

Monodromy inflation and an emergent mechanism for stabilising the cosmological constant

open access: yesJournal of High Energy Physics, 2019
We show that a pair of field theory monodromies in which the shift symmetry is broken by small, well motivated deformations, naturally incorporates a mechanism for cancelling off radiative corrections to the cosmological constant.

Why Renormalizable NonCommutative Quantum Field Theories? [PDF]

open access: yesarXiv, 2007
We complete our previous recent review on noncommutative field theory, discussing in particular the constructive aproach to the Grosse-Wulkenhaar theory. We also suggest that by gluing together many Grosse-Wulkenhaar theories at high energy one can obtain an effective commutative field theory at lower energy.

METTL3 knockout accelerates hepatocarcinogenesis via inhibiting endoplasmic reticulum stress response

open access: yesFEBS Open Bio, EarlyView.
Liver‐specific knockout of N6‐methyladenosine (m6A) methyltransferase METTL3 significantly accelerated hepatic tumor initiation under various oncogenic challenges, contrary to the previously reported oncogenic role of METTL3 in liver cancer cell lines or xenograft models. Mechanistically, METTL3 deficiency reduced m6A deposition on Manf transcripts and

Ghost free mimetic massive gravity

open access: yesJournal of High Energy Physics, 2018
The mass of the graviton can be generated using a Brout-Englert-Higgs mechanism with four scalar fields. We show that when one of these fields is costrained as in mimetic gravity, the massive gravity obtained is ghost free and consistent.
