Depicting the Non-Covalent Interaction of Whey Proteins with Galangin or Genistein Using the Multi-Spectroscopic Techniques and Molecular Docking

open access: yesFoods, 2019
The non-covalent interactions between a commercial whey protein isolate (WPI) and two bioactive polyphenols galangin and genistein were studied at pH 6.8 via the multi-spectroscopic assays and molecular docking.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

An Upgraded Line List for Radiative Transitions between the B 2Σ+, A 2Π, and X 2Σ+ States of the CN Radical

open access: yesThe Astrophysical Journal Supplement Series
The global mass-invariant coupled-channel deperturbation model of the B ^2 Σ ^+ , A ^2 Π, and X ^2 Σ ^+ states of the CN radical, which reproduces the overall rovibronic term values of mutually perturbed levels with almost spectroscopic accuracy, has ...

Determination of the spring constants of the higher flexural modes of microcantilever sensors [PDF]

open access: yes, 2013
Funding: University of St Andrews.A method for the simultaneous calibration of the spring constants of all flexural modes of microcantilevers is presented. It is based on a flow of gas from a microchannel that interacts with the microcantilever.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Hunting for Sulfur-containing Molecules in Space: A Spectroscopic Characterization of Cyclopropenethione Based on High-level Ab Initio Calculations

open access: yesThe Astrophysical Journal
Cyclopropenethione falls into the class of complex organic molecules but has not yet been observed in the interstellar medium or any circumstellar disks. However, its existence is very likely, and thus this study provides high-level ab initio predictions,

A comparative spectroscopic and computational insight on the interaction of short and long chain pyrrolidinium based ionic liquids with bovine serum albumin

open access: yesJournal of Ionic Liquids
In this study, bovine serum albumin (BSA), a model transport protein, is shown to interact with two pyrrolidinium based ionic liquids (ILs), namely, 1-hexyl-1-methyl pyrrolidinium bromide [PyrC6]Br−and 1-dodecyl-1-methyl pyrrolidinium bromide [PyrC12]Br−.
