Xenotransplantation using porcine donors is rapidly approaching clinical applicability as an alternative therapy for treatment of many end-stage diseases including type 1 diabetes. Porcine neonatal islet cell clusters (NICC) have normalised blood sugar levels for relatively short periods in the preclinical diabetic rhesus model but have met with limited success in the stringent baboon model. Here we report that NICC from genetically modified (GM) pigs deleted for αGal and expressing the human complement regulators CD55 and CD59 can cure diabetes long-term in immunosuppressed baboons, with maximum graft survival exceeding 22 months.

The reaction proceeds via tandem amide bond formation/Dohmori-Smiles rearrangement under the simple conditions of an aqueous base. In the case of -nosylamides, a further reaction takes place at the nitro group to yield indazoles.

Using carbon tetrabromide as the C1 source, ruthenium(III) trichloride catalysis enables functionalization of the arene meta-C-H position, affording carboxy methyl ester products after in situ reaction with methanol.

There is also a risk that incumbent CNS' may be redirected to less specialist work in trusts that do not appreciate the full value of the service that these nurses provide. Optimal and equitable patient access to CNS care will require the development of a strong evidence base showing that specialist nurses not only deliver patient-focused care, but that they can also help to meet healthcare managers' objectives of streamlined, cost-effective clinical services.

Design And Measurements: A randomized trial of the intervention versus a control group who received written health risk information materials only. All participants completed a baseline self-assessment questionnaire before randomization.

Objectives: To assess the use of existing libraries; usage of the Internet and biomedical databases; and need for training on use of the Internet and biomedical databases for primary care staff.
Methods: A postal survey of general practitioners (GPs), practice nurses (PNs) and practice managers (PMs) in Nottingham and Rotherham, UK.
Results: Overall, 243 questionnaires were used.
