We have tested an alternative method of delivering health services to regional areas of Queensland. By integrating telepaediatrics into an existing outreach programme for children with diabetes and endocrine conditions, we were able to reduce travel for specialist hospital staff while maintaining (and sometimes increasing) the contact patients had with the specialist team. In the first 28 months, we facilitated 160 patient consultations and 10 education sessions via videoconference through the telepaediatric service. By the end of the study, site visits were taking place annually and routine videoconference clinics were scheduled quarterly for the review of new patients and follow-up. Telepaediatric services in endocrinology and diabetes were established at three levels: the coordination of routine specialist clinics via videoconference; ad hoc patient consultations for collaborative management during acute presentations and at times of urgent clinical need; and the delivery of education to staff and patients throughout the state. The net result was improved access to specialist services from rural and remote areas of Queensland.

A growing body of evidence suggests that the Golgi complex contains an actin-based filament system. We have previously reported that one or more isoforms from the tropomyosin gene Tm5NM (also known as gamma-Tm), but not from either the alpha- or beta-Tm genes, are associated with Golgi-derived vesicles (Heimann et al., (1999). J. Biol. Chem. 274, 10743-10750). We now show that Tm5NM-2 is sorted specifically to the Golgi complex, whereas Tm5NM-1, which differs by a single alternatively spliced internal exon, is incorporated into stress fibers. Tm5NM-2 is localized to the Golgi complex consistently throughout the G1 phase of the cell cycle and it associates with Golgi membranes in a brefeldin A-sensitive and cytochalasin D-resistant manner. An actin antibody, which preferentially reacts with the ends of microfilaments, newly reveals a population of short actin filaments associated with the Golgi complex and particularly with Golgi-derived vesicles. Tm5NM-2 is also found on these short microfilaments. We conclude that an alternative splice choice can restrict the sorting of a tropomyosin isoform to short actin filaments associated with Golgi-derived vesicles. Our evidence points to a role for these Golgi-associated microfilaments in vesicle budding at the level of the Golgi complex.

Large groundwater table fluctuations were observed in a coastal aquifer during an offshore storm. The storm induced significant changes of the mean shoreline elevation, characterized by a pulse-like oscillation. This pulse propagated in the aquifer, resulting in the water table fluctuations. A general analytical solution is derived to quantify this new mechanism of water table fluctuation. The solution is applied to field observations and is found to be able to predict reasonably well the observed storm-induced water table fluctuations. Based on the analytical solution, the damping characteristics and phase shift of the oscillation as it propagates inland are examined.
