In new territory: consent and the extended duties dental nurse.

With the introduction of direct access to treatment from dental care professionals (DCPs) in 2013, dental nurses are being trained to support the wider dental team in a number of additional skills. The name for this expanded team role is Extended Duties Dental Nurse (EDDN). These new duties take the EDDN into new territories, one of which includes the issue of consent.

Development and genetic mapping of sequence-tagged microsatellites (STMs) in bread wheat (Triticum aestivum L.).

The density of SSRs on the published genetic map of bread wheat (Triticum aestivum L.) has steadily increased over the last few years. This has improved the efficiency of marker-assisted breeding and certain types of genetic research by providing more choice in the quality of SSRs and a greater chance of finding polymorphic markers in any cross for a chromosomal region of interest.

Genes co-amplified with MYCN in neuroblastoma: silent passengers or co-determinants of phenotype?

Amplification of the MYCN oncogene in neuroblastoma is associated with poor prognosis. The amplified unit of DNA can be up to 1 Mb in size and so could contain additional genes that affect tumour phenotype. Identification of such genes may assist in optimising the determination of prognosis, and could provide new targets for treatment.

Association of the signaling adaptor FRS2 with fibroblast growth factor receptor 1 (Fgfr1) is mediated by alternative splicing of the juxtamembrane domain.

Fibroblast growth factor receptors (FGFRs) are a family of transmembrane tyrosine kinases involved in signaling via interactions with the family of fibroblast growth factors. Alternative splicing of the juxtamembrane region of FGFR1-3 leads to the inclusion or exclusion of two amino acids, valine and threonine, the VT site. The presence or absence of VT (VT+ or VT-, respectively) affects the signaling potential of the receptor.

Activation by reduction of the resting form of cytochrome c oxidase: tests of different models and evidence for the involvement of CuB.

(1) The reaction of the resting form of oxidised cytochrome c oxidase from ox heart with dithionite has been studied in the presence and absence of cyanide. In both cases, cytochrome a reduction in 0.1 M phosphate (pH 7) occurs at a rate of 8.
