OBJECTIVE IL-23 is a pro-inflammatory cytokine proposed to be central to the development of autoimmune disease. We investigated whether IL-23, together with the downstream mediator IL-17A, was present and functional in RA in humans. METHODS RA synovial cells were cultured in the presence or absence of antibodies directed against IL-23p19 or -23R and -17. IL-23, -12, -17, and their receptors, ...

The remarkable scientific work on fertility preservation that is documented in the early chapters of this volume will inevitably give rise to moral and religious questions about the use of technology to reproduce. In this regard, oncofertility is no different from other forms of assisted reproduction that have led to extensive debate among ethicists and moral theologians. In the case of many fo...

Background. There is a need in primary care for simple asthma outcome measures that are valid in terms of their relationship with lung function and capable of predicting those patients for whom additional management is indicated. Aim. To assess the predictive validity of a revised asthma morbidity index in United Kingdom (UK) general practice. Method. Morbidity index and peak flow rate data wer...
