The impact of site of graduate medical education training and other factors on physician employee retention.

This study sought to determine if the site of graduate medical training or other factors impact the length of institutional employment. Physician hires for the home institution were catalogued from January 1, 1996, through December 31, 2006. In analyzing the 253 physician hires, we found no statistically significant advantage in employee retention associated with hiring "one's own" or with U.

Neonatal presentations to a Mixed Emergency Department.

Aims: To investigate the characteristics of neonates presenting to a metropolitan Mixed Emergency Department (MED). To examine whether there are maternal and neonatal characteristics which increase the risk of presentation to the ED in the neonatal period.

Methods: A retrospective chart review was performed of all neonatal presentations occurring between July 2002 and June 2003 to Liverpool Hospital Emergency Department, a Level 6 MED located in south-western Sydney, New South Wales, Australia, seeing approximately 45,000 presentations annually of which 20% are paediatric.

Leptin increases expression and activity of matrix metalloproteinase-2 and does not alter collagen production in rat glomerular mesangial cells.

Obesity is a leading risk factor for the development of nephropathy. In nephropathy, one of the major structural alterations found in the kidney is the increase in, or altered profile of, extracellular matrix (ECM) proteins such as collagen. Excessive synthesis and decreased degradation of matrix proteins by proteases such as matrix metalloproteinases (MMPs) may contribute to this process.

The first year of a formal emergency medicine training programme in Papua New Guinea.

Objective: To describe a programme catalyzing the development of emergency medicine in Papua New Guinea (PNG).

Methods: Five emergency physicians rotated through a new position of Senior Lecturer in Emergency Medicine in the University of PNG during 2003. The position was established as a consequence of emergency physician input supported by AusAID in 2002.

Dmc1 fluorescent foci in prophase I nuclei of diploid, triploid and hybrid lilies.

We examined the distribution of meiotic epitopes for the Dmc1 protein of lilies in a normal diploid, a triploid, and in a diploid species-hybrid. The triploid has an extra chromosome set; all three sets align, but only two of the three axes intimately pair at a given location. Our findings with the triploid support the idea that retention of the foci until the pachytene stage requires a successful homology check and synaptonemal complex (SC) initiation; the number of foci in the triploid diminishes by approximately 30% from early zygotene to pachytene, and the triploid pachytene values are similar to the pachytene values of the diploid.
