We characterise the structural properties of the quasi-liquid layer (QLL) at two low-index ice surfaces in the presence of sodium chloride (Na$^+/$Cl$^-$) ions by molecular dynamics simulations. We find that the presence of a high surface density of

Outstanding questions about the RNA world hypothesis for the emergence of life on Earth concern the stability and self-replication of prebiotic aqueous RNA. Recent experimental work has suggested t...

We investigate the effect of molecular geometry and conformational flexibility on electronic coupling and charge transfer interactions within propeller-shaped perylene diimide (PDI) tetramer arrays differing by the number of covalent linkages to a ce

Heating of dilute aqueous solutions of simple aldoses at 50° induces marked alteration in the electronic absorption spectra of the sugars. Maxima at 230 mμ and 275 mμ, and low-intensity peaks at 325 mμ and 350 mμ, appear as a function of the tim

N-Glycosidic coupling of aldoses and the free amino groups of protein is accompanied by profound modification of the ultraviolet absorption spectrum of the protein partner in the Maillard reaction. The increased extinction coefficient at 250 mμ of p

Dialyzed aqueous extracts of plant pollen are widely used in the clinical practice of allergy for diagnostic and therapeutic purposes. The present investigation shows that such allergenic extracts are capable of consuming complement in every human se

It is known that the skin-active and IgE-binding components in Parietaria pollen extracts are not restricted to the predominant protein allergens of Mr 12 000–15 000, but are present as well among the naturally occurring constituents of Mr < 10 000

The distribution and affinity of IgG subclasses against various aeroallergens were assessed by inhibition of specific antibody binding. Two parameters from the dose-response curves were taken as indicative of antibody affinity : the point of 50% inhi

Among the highly heterogeneous components of the mouse urinary protein complex (MUP) a hydrolase was detected which was capable of spliting the proteinase ester substrate TAME as well as a synthetic chromogenic tripeptide specific for tissue and urin
