Vibrational energy relaxation (VER) of a CD stretching mode in cytochrome c [PDF]
arXiv, 2004 We first review how to determine the rate of vibrational energy relaxation (VER) using perturbation theory. We then apply those theoretical results to the problem of VER of a CD stretching mode in the protein cytochrome c. We model cytochrome c in vacuum as a normal mode system with the lowest-order anharmonic coupling elements. We find that, for the ``

Imaging cytochrome C oxidase and FoF1-ATP synthase in mitochondrial cristae of living human cells by FLIM and superresolution microscopy [PDF]
arXiv, 2017 Cytochrome C oxidase and FoF1-ATP synthase constitute complex IV and V, respectively, of the five membrane-bound enzymes in mitochondria comprising the respiratory chain. These enzymes are located in the inner mitochondrial membrane (IMM), which exhibits large invaginations called cristae.

Leveraging Multifaceted Polyphenol Interactions: An Approach for Hair Loss Mitigation
Advanced Materials Interfaces, EarlyView.This study presents tannic acid as an effective alternative to traditional hair loss treatments. Acting as an adhesion mediator, tannic acid binds to keratin on the hair surface and sequesters SCANDAL—a blend of salicylic acid, niacinamide, and dexpanthenol—allowing gradual release to hair follicles.

Advanced Synthesis &Catalysis, EarlyView.Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Vibrational energy relaxation (VER) of isotopically labeled amide I modes in cytochrome c: Theoretical investigation of VER rates and pathways [PDF]
arXiv, 2007 Using a time-dependent perturbation theory, vibrational energy relaxation (VER) of isotopically labeled amide I modes in cytochrome c solvated with water is investigated. Contributions to the VER are decomposed into two contributions from the protein and water.

Inhalable Hsa‐miR‐30a‐3p Liposomes Attenuate Pulmonary Fibrosis
Advanced Science, EarlyView.The study explores inhalable hsa‐miR‐30a‐3p‐loaded liposomes as a treatment for bleomycin‐induced pulmonary fibrosis in mice. Hsa‐miR‐30a‐3p is electroporated into liposomes and formulated into a dry powder for inhalation. Delivered via dry powder inhalation, it improves pulmonary function, promotes myofibroblast de‐differentiation by targeting CNPY2 ...

Dynamics of protein-protein encounter: a Langevin equation approach with reaction patches [PDF]
, 2008 We study the formation of protein-protein encounter complexes with a Langevin equation approach that considers direct, steric and thermal forces. As three model systems with distinctly different properties we consider the pairs barnase:barstar, cytochrome c:cytochrome c peroxidase and p53:MDM2.

Molecular Dynamics Simulations of Cytochrome c un-folding in AOT Reverse Micelles: the first steps [PDF]
arXiv, 2009 This paper explores the reduced form of horse cytochrome c confined in reverse micelles (RM) of so-dium bis-(2-ethylhexyl) sulfosuccinate (AOT) in isooctane by molecular dynamics simulation. RMs of two sizes were constructed at a water content of Wo = [H2O]/[AOT] = 5.5 and 9.1.
