Diversity and evolutionary history of lettuce necrotic yellows virus in Australia and New Zealand.

Lettuce necrotic yellows virus (LNYV) is the type member of the genus Cytorhabdovirus, family Rhabdoviridae, and causes a severe disease of lettuce (Lactuca sativa L.). This virus has been described as endemic to Australia and New Zealand, with sporadic reports of a similar virus in Europe.

Fathers, daughters, and anorexia nervosa.

Purpose: The study described the nature and meaning of the father-daughter relationship throughout the daughter's (N = 11) life from the perspective of the daughter, who has been in a 2-year recovery from anorexia nervosa (AN). Particular consideration was given to the changes over time.

Design And Methods: A narrative analysis method was used to examine the daughter's stories.

Parental presence during pediatric invasive procedures.

Parental presence during pediatric invasive procedures is becoming more common, yet it remains a controversial issue related to providing family-centered care. A literature review related to this important issue was performed. Credible arguments supporting parental presence during invasive procedures as well as opposing arguments were discussed.

The NDNQI-Adapted Index of work satisfaction.

The valid measurement of nurses' job satisfaction is critical because job satisfaction is important for the retention of qualified nurses to provide patient care in hospitals. Two studies were conducted to adapt the Stamps Index of Work Satisfaction (1997b) to measure work satisfaction at the patient care unit level for use by the National Database of Nursing Quality Indicators (NDNQI). In Study 1 (n = 918 RNs) exploratory factor analysis of data obtained using the NDNQI-Adapted Index replicated the conceptual dimensions of the Stamps measure.

Effect of distance and infusion rate on operation of Medfusion 2010 infusion pump during magnetic resonance imaging.

Study Objectives: To determine the accuracy and reliability of intravenous infusion, as well as magnetic resonance image effect of the Medfusion 2010 infusion pump (Medex Medical Supplies, Inc., Duluth, GA) at distances of 2, 4, 8, 12, and 16 feet from a 1.5 Tesla MRI magnet over a four-week time interval, using infusion rates that would correspond to those of propofol administration.

Ultrastructural evidence for two-cell and three-cell neural pathways in the tentacle epidermis of the sea anemone Aiptasia pallida.

Sensory and ganglion cells in the tentacle epidermis of the sea anemone Aiptasia pallida were traced in serial transmission electron micrographs to their synaptic contacts on other cells. Sensory cell synapses were found on spirocytes, muscle cells, and ganglion cells. Ganglion cells, in turn, synapsed on sensory cells, spirocytes, muscle cells, and other neurons and formed en passant axo-axonal synapses.
