FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Nature Communications, 2022 By using laser tweezers, the authors show that a single α-catenin molecule does not resist force on F-actin. However, clustering of multiple molecules and force applied toward F-actin pointed end engage a molecular switch in α-catenin, which unfolds and ...

Identification of novel small molecule inhibitors of ETS transcription factors
FEBS Letters, EarlyView.ETS transcription factors play an essential role in tumourigenesis and are indispensable for sprouting angiogenesis, a hallmark of cancer, which fuels tumour expansion and dissemination. Thus, targeting ETS transcription factor function could represent an effective, multifaceted strategy to block tumour growth. The evolutionarily conserved E‐Twenty‐Six

Encoding terahertz holographic bits with a computer-generated 3D-printed phase plate
Scientific ReportsA sub-terahertz holographic image of a two-dimensional 576-bit data code is produced using a diffractive phase-plate element. The phase plate was designed using a modified Gerchberg-Saxton iterative algorithm to encode a focused image of the data code ...

Magnetic field profiling for selected-states magnetic-resonance spectroscopy (SSMRS) and Stern-Gerlach spectroscopy (MGRS) in condensed matter [PDF]
, 1998 A method was presented of profiling the magnetic field, with a zero vector of magnetic flux density $B_{r}$ and strong gradient G, enabling conditions for the Stern-Gerlach spectroscopy to be accomplished in condensed matter (the method has been called magnetic field gradient spectroscopy - MGRS), as well the previously proposed magnetic resonance ...

Enhancing sensitivity in absorption spectroscopy using a scattering cavity [PDF]
arXiv, 2021 Absorption spectroscopy is widely used to detect samples with spectral specificity. Here, we propose and demonstrate a method for enhancing the sensitivity of absorption spectroscopy. Exploiting multiple light scattering generated by a boron nitride (h-BN) scattering cavity, the optical path lengths of light inside a diffusive reflective cavity are ...
