Supporting relationships between family and staff in continuing care settings.

In this Canadian study, a participatory action research approach was used to examine the relationships between families of residents of traditional continuing care facilities and the health care team. The objectives were to (a) explore the formation and maintenance of family-staff relationships, with attention paid to the relational elements of engagement and mutual respect; (b) explore family and staff perspectives of environmental supports and constraints; and (c) identify practical ways to support and enhance these relationships. Results indicate that the resource-constrained context of continuing care has directly impacted family and staff relationships.

Protein kinase A modulates A-type potassium currents of larval zebrafish (Danio rerio) white muscle fibres.

Aims: Potassium (K(+)) channels are involved in regulating cell excitability and action potential shape. To our knowledge, very little is known about the modulation of A-type K(+) currents in skeletal muscle fibres. Therefore, we sought to determine whether K(+) currents of zebrafish white skeletal muscle were modulated by protein kinase A (PKA).

Development of ionic currents of zebrafish slow and fast skeletal muscle fibers.

Voltage-gated Na+ and K+ channels play key roles in the excitability of skeletal muscle fibers. In this study we investigated the steady-state and kinetic properties of voltage-gated Na+ and K+ currents of slow and fast skeletal muscle fibers in zebrafish ranging in age from 1 day postfertilization (dpf) to 4-6 dpf. The inner white (fast) fibers possess an A-type inactivating K+ current that increases in peak current density and accelerates its rise and decay times during development.
