Nitrogen fixation by the cyanobacterium Anabaena is carried out in heterocysts, specialized, non-dividing cells which differentiate under conditions of ammonia or nitrate deprivation. In Anabaena, heterocyst differentiation is accompanied by rearrangement of some nitrogen fixation genes. A site-specific recombination between an 11 base-pair direct repeat(More)
BACKGROUND Determination of seabird diet usually relies on the analysis of stomach-content remains obtained through stomach flushing; this technique is both invasive and logistically difficult. We evaluate the usefulness of DNA-based faecal analysis in a dietary study on chick-rearing macaroni penguins (Eudyptes chrysolophus) at Heard Island. Conventional(More)
BACKGROUND The best care and management of patients in persistent vegetative state (PVS) has been the subject of sustained moral and legal debate for a number of years. However, the views of clinicians in the UK involved in caring for patients in PVS are largely unknown. METHODS A postal questionnaire was sent to 1882 consultant members of the British(More)
BACKGROUND & AIMS Early fluid resuscitation is recommended to reduce morbidity and mortality among patients with acute pancreatitis, although the impact of this intervention has not been quantified. We investigated the association between early fluid resuscitation and outcome of patients admitted to the hospital with acute pancreatitis. METHODS(More)
OBJECTIVE Even with the best available treatment, most bulimia nervosa (BN) sufferers are not symptom free at the end of therapy and, for those who have achieved remission, risk of relapse is high. Thus, there is a need for aftercare or relapse prevention interventions after therapy. It is not yet known what type of intervention should be delivered, and how(More)
AIMS AND OBJECTIVES The present study aimed to investigate the competencies of qualifiers from three-year degree and three-year diploma courses in England at one, two and three years after qualification. BACKGROUND The provision of three-year preregistration nursing degrees in the UK has increased in recent years and in many colleges degrees are offered(More)
In recent years, there has been a growing emphasis on nurses obtaining degrees with many arguing for an all graduate profession. Traditionally trained nurses may feel increased pressure to obtain degrees to compete with their diploma and degree trained successors. This paper presents findings from the sixth questionnaire in a Department of Health-funded,(More)
BACKGROUND Increasing mobility of healthcare professionals has led to concerns that certain countries or regions are depleted of sufficient staff to meet healthcare needs. In formulating appropriate strategies to ensure better retention locally, human resource managers are hindered by lack of information about migration patterns. PURPOSE AND AIMS Purposes(More)

The book is written for 11-16 year olds as a first step intervention for reducing mild to moderate symptoms of OCD. AIMS This report describes a preliminary evaluation of the feasibility and acceptability of the book as a(More)
The structural genes for nitrogenase and nitrogenase reductase have been cloned from Anabaena and physically mapped. The map differs from that of Klebsiella in several ways, including the insertion of 11 kbp between nifK and nifD in Anabaena. One nif RNA transcript has been studied in detail and shown to originate from a site in the Anabaena chromosome(More)
