Molecular Simulations of Interacting Nanocrystals
Nano Letters, 2008We compute the potential of mean force for two gold nanocrystals capped by alkylthiols from atomistic simulations and show how variables such as temperature, capping molecule length, and the presence of solvent affect these interactions. Our main findings are (1) the equilibrium distance in vacuum always equals approximately 1.25 times the core ...

Molecular Interactions of Aging and Cancer
Clinics in Geriatric Medicine, 1997The increased incidence of cancer as a function of age has long been interpreted to suggest that multiple genetic changes are required for tumorigenesis. Cancer cells differ from normal cells in many characteristics, including loss of differentiation, increased invasiveness, and decreased drug sensitivity. Although recent molecular advances have helped

Molecular interactions in the eye lens
Biochemical Society Transactions, 1991Introduction The lens is a cellular structure formed from elongated fibre cells aligning into concentric layers that stack together with the organization of a uni-axial crystal 111. Within the fibre cells, where protein turnover is low, protein components are packed together [2-41 with short-range order [S].

Interaction Terms in Molecular Vibrations
Nature, 1947We have recently been investigating the magnitudes and signs of the interaction terms in the potential functions of triatomic molecules XYZ. These arise from interactions between two bond-lengths (XY and YZ), or between one bond-length and the angle XYZ. In our study of these terms we have distinguished three distinct effects: (1) resonance effects; (2)

A Bayesian molecular interaction library
Journal of Computer-Aided Molecular Design, 2003We describe a library of molecular fragments designed to model and predict non-bonded interactions between atoms. We apply the Bayesian approach, whereby prior knowledge and uncertainty of the mathematical model are incorporated into the estimated model and its parameters.

Molecular Interaction of Phlorizin and Cyclodextrins
Journal of Inclusion Phenomena, 1984The molecular interaction between phlorizin and cyclodextrin(CD) in aqueous solution is studied using the NMR spectroscopic method. From the chemical shifts of the 13-C and 1-H signals, it is concluded that a phlorizin molecule enters into the hydrophobic space of β-CD or γ-CD and makes a loose molecular complex with β-CD or γ-CD. The fact that the H-D

Molecular Modeling of Chemoreceptor:Ligand Interactions
2018Docking algorithms have been widely used to elucidate ligand:receptor interactions that are important in biological function. Here, we introduce an in-house developed docking-refinement protocol that combines the following innovative features. (1) The use of multiple short molecular dynamics (MD) docking simulations, with residues within the binding ...

MOLECULAR INTERACTIONS OF CANCER AND AGE
Hematology/Oncology Clinics of North America, 2000The authors believe that the aging process--the loss of youthful resilience--is caused by the decline of many hormones. By restoring these hormone levels, the decay associated with old age can be eliminated and in some cases, perhaps reversed. The hormones that naturally occur in the body should be replenished through a medically sound regimen.

Molecular interactions of the IGF system
Cytokine & Growth Factor Reviews, 2005The insulin-like growth factor (IGF) system is a complex network of two soluble ligands; several cell surface transmembrane receptors and six soluble high-affinity binding-proteins. The IGF system is essential for normal embryonic and postnatal growth, and plays an important role in the function of a healthy immune system, lymphopoiesis, myogenesis and

Monitoring Molecular Interactions by NMR
2008The ability of proteins to interact with small molecules or other proteins is essential in all aspects of biology. In many cases these interactions cause detectable changes in NMR chemical shifts, lineshapes, and relaxation rates and therefore provide a means by which to study these biologically important phenomena. Here we review the theory upon which
