Studies of the properties of the ice nucleation structure exposed on the surfaces of various bacteria such as Pseudomonas syringae, Erwinia herbicola, or various strains of Ice+ recombinant Escherichia coli have shown that there are clearly three major related but chemically distinct types of structures on these cells. First, the ability of Ice+ cells to(More)
BACKGROUND Information on the neonatal exposure to excipients is limited. Our aim was to describe the extent of excipient intake by Estonian neonates; to classify the excipients according to potential neonatal toxicity and thereby to measure the extent of exposure of neonates to potentially harmful excipients. METHODS A prospective cohort study that(More)
OBJECTIVES To present the clinical and sociodemographic characteristics of patients referred to a New Zealand early intervention for psychosis service and to describe the pathways to care for these patients. METHOD Clinical and sociodemographic characteristics were examined in 200 patients consecutively admitted to an early psychosis service over a 5-year(More)

People in the general population are typically very poor at detecting changes in pictures of complex scenes. The degree of this 'change blindness', however, varies with the content of the scene: when an object is semantically important or contextually inappropriate, people may be more effective at detecting changes. Two experiments investigated change(More)
OBJECTIVE(S) To obtain reliable information about the incidence of adverse drug reactions, and identify potential areas where intervention may reduce the burden of ill-health. DESIGN Prospective observational study. SETTING A large tertiary children's hospital providing general and specialty care in the UK. PARTICIPANTS All acute paediatric admissions(More)
BACKGROUND ciprofloxacin has no marketing authorization for use in neonates worldwide but it is prescribed for the treatment of neonatal life-threatening infections, mainly in developing countries and in Europe. Given the concerns about its toxicity in this population and the necessity for its use in specific clinical situations, we conducted a systematic(More)
The placenta is essential to nutrition before birth. Recent work has shown that a range of clearly defined alterations can be found in the placentas of infants with intrauterine growth restriction (IUGR). In the mouse, a placental specific knockout of a single imprinted gene, encoding IGF-2, results in one pattern of alterations in placenta structure and(More)
Nonprotein components attached to the known protein product of the inaZ gene of Pseudomonas syringae have been identified and shown to be necessary for the most efficient ice nucleation of supercooled H2O. Previous studies have shown that cultures of Ina+ bacteria have cells with three major classes of ice-nucleating structures with readily differentiated(More)
The preliminary finding that nonprotein additions to the protein product of the ice-nucleating gene of Pseudomonas syringae or Erwinia herbicola are essential for ice nucleation at the warmest temperatures has led to experiments aimed at identifying possible linkages between the ice protein and the other components. It appears that the protein is coupled to(More)
