Medical Care Provider Involvement in Ontario Assisted Living Homes: A Descriptive Cross-Sectional Survey Analysis.

Objectives: Assisted living is growing in Ontario. Medical services are not regulated in Ontario, resulting in variability of physician involvement. We described medical service provider involvement and practice characteristics in assisted living homes.

Simulations to derive membrane resistivity in three phenotypes of guinea pig sympathetic postganglionic neuron.

The electrotonic behavior of three phenotypes of sympathetic postganglionic neuron has been analyzed to assess whether their distinct cell input capacitances simply reflect differences in morphology. Because the distribution of membrane properties over the soma and dendrites is unknown, compartmental models incorporating cell morphology were used to simulate hyperpolarizing responses to small current steps. Neurons were classified as phasic (Ph), tonic (T), or long-afterhyperpolarizing (LAH) by their discharge pattern to threshold depolarizing current steps and filled with biocytin to determine their morphology.

The effects of simulated spring goose grazing on the growth rate and protein content of Phleum pratense leaves.

The effects of simulated goose grazing on Phleum pratense plants were tested in an Iceland hayfield during the spring goose staging period (19 April-11 May 1997). Plants in an area exclosed from the influence of grazing and the nutrient effects of goose faeces were subject to the removal of the youngest lamina once, three and four times during this period. Clipping three and four times resulted in 25-41% increases in cumulative elongation of youngest laminae compared with unclipped plants.
