The traditional Chinese medicine, Qianhu, which consists of the roots of Peucedanum praeruptorum DUNN. and P. decursivum MAXIM. (Umbelliferae), is used for treatment of respiratory disease and pulmonary hypertension. In the course of our search for the active ingredients of Qianhu, we have reported the structures and biological activities of coumarins isolated from both plants. We isolated the ...

A number of additional purines and pyrimidines have recently been described as minor constituents of ribonucleic acids. Cohn (1957, 1958, 1959) and Davis & Allen (1957) have described an unusual pyrimidine nucleotide from yeast ribonucleic acid, thymine, 2-methyladenine, 6-methylaninopurine and 6-dimethylaminopurine have been identified as components ofribonucleic acid from several sources (Lit...

In the last decade, genomics has come to play a central role in systematics and biodiversity research. In coming years, systematics and phylogenetics will come to play an increasingly important role in genomics. Here,...

We investigate the notion of classical negation from a non-classical perspective. In particular, one aim is to determine what classical negation amounts to in a paracomplete and paraconsistent four-valued setting. We first give a general semantic characterization of classical negation and then consider an axiomatic expansion BD+ of four-valued Belnap–Dunn logic by classical negation. We show th...

Our hope is that the new space created will not only enable us to fill our vacant posts with scientists at the highest level, but will also allow us to harbour more joint appointments with the Clinical School. In the past 15 years the Dunn School has undertaken a very high level of rebuilding and refurbishment activity, all aimed at maintaining the Department as a worldleader in biomedical rese...

The shoulder as the most mobile joint in the body has a complex anatomy providing it with an increased range of motion, at the expense of its stability. The complex of ligaments and tendons around the acromioclavicular joint (ACJ) is prone to injury especially during sporting activity or following falls onto the apex of the shoulder. The original classification of ACJ dislocations having been m...
