A process of decision-making support: Exploring supported decision-making practice in Canada.

Canada was the first country to develop legal mechanisms that allow for supported decision making, and little research has explored how decision making is supported in this context. This research aimed to understand how seven people with intellectual disabilities, living in two Canadian provinces, were supported with their decision making. The research used constructivist grounded theory methodology, interviewing and observing the decision making of seven people with mild to severe intellectual disabilities and 25 decision supporters.

Validation of the use of long-term indwelling jugular catheters in a rat model of cardiotoxicity.

Doxorubicin administered to rats induces a dose-dependent cardiomyopathy. Both doxorubicin administration and the presence of indwelling catheters have been associated with thrombus formation. We sought to determine feasibility of drug delivery and degree of thrombogenesis related to long-term indwelling catheter use in a cardiotoxicity model.

Role of reactive nitrogen species in development of hepatic injury in a C57bl/6 mouse model of human granulocytic anaplasmosis.

Human granulocytic anaplasmosis (HGA), caused by the granulocytic rickettsia-like organism Anaplasma phagocytophilum, is the 3rd most frequent vector-borne infection in North America. To understand the disease mechanisms of HGA, we developed a murine model that lacks clinical disease yet exhibits characteristic histopathologic and immunologic changes. Because the degree of hepatic histopathology is unrelated to high bacterial numbers, tissue injury in HGA is thought to occur due to products of innate immunity, such as nitric oxide (NO) and reactive nitrogen species (RNS) from cytokine-activated macrophages.

Insulin-like growth factor-I improves cerebellar dysfunction but does not prevent cerebellar neurodegeneration in the calcium channel mutant mouse, leaner.

The effects of insulin-like growth factor-I (IGF-I) on cerebellar dysfunction and neurodegeneration were investigated in leaner mice, which exhibit cerebellar ataxia and neurodegeneration related to P/Q-type calcium channel mutations. Leaner mice showed significantly reduced serum and cerebellar IGF-I concentrations compared to wild-type mice at postnatal day 30. Behavioral assessment of leaner mice injected with IGF-I subcutaneously for 4 weeks showed partially improved cerebellar function.
