DiGeorge syndrome is characterized by cardiovascular, thymus and parathyroid defects and craniofacial anomalies, and is usually caused by a heterozygous deletion of chromosomal region 22q11.2 (del22q11) (ref. 1). A targeted, heterozygous deletion, named Df(16)1, encompassing around 1 megabase of the homologous region in mouse causes cardiovascular(More)
Del22q11 syndrome is caused by heterozygous deletion of an approximately 3 Mb segment of chromosome 22q11.2. Children diagnosed with del22q11 syndrome commonly have learning difficulties, deficits of motor development, cognitive defects and attention deficit disorder. They also have a higher than normal risk for developing psychiatric disorders, mainly(More)
The heterozygous chromosome deletion within the band 22q11 (del22q11) is an important cause of congenital cardiovascular defects. It is the genetic basis of DiGeorge syndrome and causes the most common deletion syndrome in humans. Because the deleted region is largely conserved in the mouse, we were able to engineer a chromosome deletion (Df1) spanning a(More)
From July through September 2000, patients in five European countries were infected with a multidrug-resistant strain of Salmonella Typhimurium DT204b. Epidemiologic investigations were facilitated by the transmission of electronic images (Tagged Image Files) of pulsed-field gel electrophoresis profiles. This investigation highlights the importance of(More)
Subcutaneous and intracranial VMDk tumours were treated with photodynamic therapy (PDT) using a new sensitiser, m-THPP. Subcutaneous tumours were highly sensitive to PDT but intracranial tumours were much more resistant, requiring a 30-fold increase in sensitiser dose to produce equivalent levels of necrosis. Resistance of intracerebral tumours was not due(More)
We quantified the effects of exotic annual grass invasion on the ground-layer structure of grassy eucalypt woodlands, with the aim of determining if weed invasion decreased gap size and plant basal area leading to reduced spatial heterogeneity. We measured plant density, distance between plants and basal plant area in woodland sites which ranged from zero(More)
BACKGROUND As part of needs assessment processes, our Faculty of Medicine (FOM) continuing professional development office investigated the differences between physicians who do and those who do not frequently participate in planned group learning to gain insight into their interest in new forms of continuing professional development (CPD). METHOD We sent(More)
