Tunable reflected group delay from the graphene/hBN heterostructure at infrared frequencies

Results in Physics, 2019
In this paper, we theoretically investigated the reflected group delay from the graphene/hexagonal boron nitride (hBN) heterostructure in the infrared band.

Interferon beta drives therapy resistance in a patient‐derived model of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Enhanced Reflected Group Delay with Optical Tamm State via Graphene-Dielectric Bragg Mirror Configuration

Advances in Condensed Matter Physics, 2019
Group delay of the optical pulse reflected from the structure composed of graphene and one dimensional photonic crystal (1D PC) is studied. It is shown that the large negative group delay in this configuration can be realized due to the excitation of the

Tunable Group Delay of the Optical Pulse Reflection From Fabry–Perot Cavity With the Insertion of Graphene Sheets

IEEE Photonics Journal, 2014
We have theoretically investigated the group delay of the TE-polarized beam reflected from a Fabry-Perot cavity with the insertion of the graphene sheets in the near-infrared band.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Tunable and light-controllable bistable reflected group delay based on nonlinear surface plasmon resonance with graphene

Results in Physics, 2019
In this paper, we have shown that tunable nonlinear group delay of reflected light beam at terahertz frequencies can be achieved by a modified Otto configuration with the insertion of monolayer graphene and nonlinear substrate.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...
