1. A method is described for determining the refractory period of the dog's auricle during the normal sinus rhythm. The advantages of the method are: (a) The total stimulating effects of repeated induction shocks are avoided. (b) The action current is recorded from a point one millimeter or less from the point of stimulation. (c) Alterations in the(More)
Since its discovery 40 years ago, fibroblast growth factor (FGF) receptor (FGFR) signalling has been found to regulate fundamental cellular behaviours in a wide range of cell types. FGFRs regulate development, homeostasis, and repair and are implicated in many disorders and diseases; and indeed, there is extensive potential for severe consequences, be they(More)
3D modelling fulfils a critical role in research, allowing for complex cell behaviour and interactions to be studied in physiomimetic conditions. With tissue banks becoming established for a number of cancers, researchers now have access to primary patient cells, providing the perfect building blocks to recreate and interrogate intricate cellular systems in(More)
The determination of the percentage of CO(2) in the alveolar air, by the method of Haldane and Priestley, is sufficiently accurate for clinical purposes when the individual is at rest. It is evident, however, that an error may arise in the determination of the percentage of CO(2) in the alveolar air, due to the time during the forced expiration, short of(More)
We report a case of liver herniation through an occult diaphragmatic injury presenting as a solitary pulmonary nodule. The value of clinical history as well as the utility of helical computed tomography and magnetic resonance imaging in avoiding this pitfall are discussed.
It is becoming increasingly evident that multiple cell types within the tumor work together to drive tumour progression and impact on both the response to therapy and the dissemination of tumour cells throughout the body. Fibroblast growth factor signalling (FGF) is perturbed in a number of tumors, serving to drive tumor cell proliferation and migration,(More)
