Cooperative Binding [PDF]

open access: yesPLoS Computational Biology, 2013
Molecular binding is an interaction between molecules that results in a stable association between those molecules. Cooperative binding occurs if the number of binding sites of a macromolecule that are occupied by a specific type of ligand is a nonlinear function of this ligand's concentration.

Epigenetic Regulation of Epidermal Differentiation

open access: yesEpigenomes, 2021
The epidermis is the outer part of the skin that protects the organism from dehydration and shields from external insults. Epidermal cells, called keratinocytes, undergo a series of morphological and metabolic changes that allow them to establish the ...

Ion‐Pair Binding: Is Binding Both Binding Better?

open access: yesChemistry – A European Journal, 2009
AbstractIt is often tempting to explain chemical phenomena on the basis of intuitive principles, but this practice can frequently lead to biased analysis of data and incorrect conclusions. One such intuitive principle is brought into play in the binding of salts by synthetic receptors.

Pneumococcal vaccination responses in adults with subnormal IgG subclass concentrations

open access: yesBMC Immunology, 2019
Background We sought to compare Pneumovax®23 responses in adults with subnormal IgG subclass concentrations. We studied adults with normal total IgG, frequent/severe respiratory infection, and subnormal IgG1, IgG3, or IgG1 + IgG3 before and after ...

Hair-Metal Binding [PDF]

open access: yesEnvironmental Health Perspectives, 1974
Extensive ambient extraction of several metals from human hair compromises some assumptions concerning the binding of metals to hair and the biochemical process of metal incorporation into hair. Hair metal concentrations can reveal metal intoxications and metal deficiencies.The scalp hair selected for investigation included specimens of different ...
