An exploratory study investigating the barriers to reporting child dental neglect concerns among general medical practitioners in Greater Manchester.

Introduction Dental neglect presents a global concern and is a shared public challenge for all healthcare professionals, including general medical practitioners (GPs). Previous literature highlights a lack of training among GPs and suggests that barriers are present to reporting concerns of dental neglect.Aims To investigate the current awareness of child dental neglect among GPs in Greater Manchester and to investigate barriers to the reporting of concerns.

Isolation and characterisation of a cDNA encoding a zona pellucida protein (ZPB) from the marsupial Trichosurus vulpecula (brushtail possum).

We have cloned a cDNA containing the entire coding sequence of a marsupial (the brushtail possum, Trichosurus vulpecula) zona pellucida protein (ZPB). The open reading frame of 1,581 nt is predicted to encode a ZPB polypeptide of 527 amino acids which contains 20 cysteine residues, 7 potential N-linked glycosylation sites, a potential N-terminal signal peptide and a potential C-terminal trans-membrane domain, preceded by a furin proteolytic processing signal. Sequence comparisons between possum ZPB and orthologous polypeptides from 7 eutherian species and from Xenopus laevis, reveal the existence of a high degree of sequence similarity, particularly in the central portion of the molecule.

Properties and uses of embryonic stem cells: prospects for application to human biology and gene therapy.

Embryonic stem cells are pluripotent cells derived from the early mouse embryo that can be propagated stably in the undifferentiated state in vitro. They retain the ability to differentiate into all cell types found in an embryonic and adult mouse in vivo, and can be induced to differentiate into many cell types in vitro. Exploitation of ES cell technology for the creation of mice bearing predetermined genetic alterations has received widespread attention because of the sophistication that it brings to the study of gene function in mammals.
