Animal Ghosts at Canadian Universities: The Politics of Concealment and Transparency.

For many years, the lives of animals used for research in Canadian universities have been hidden from public view due both to physical concealment (e.g., security procedures and impenetrable labs) and administrative concealment (non-disclosure of information).

Muscle atrophy in chronic kidney disease results from abnormalities in insulin signaling.

Muscle atrophy is a significant consequence of chronic kidney disease that increases a patient's risk of mortality and decreases their quality of life. The loss of lean body mass results, in part, from an increase in the rate of muscle protein degradation. In this review, the proteolytic systems that are activated during chronic kidney disease and the key insulin signaling pathways that regulate the protein degradative processes are described.

Gestational diabetes mellitus: physical exercise and health outcomes.

Purpose: Gestational diabetes mellitus (GDM) is a serious complication of pregnancy associated with increased risk of adverse outcomes for both mother and infant. This study assesses the association of maternal exercise during GDM pregnancy and selected maternal and infant adverse GDM-related outcomes. The analysis uses information derived from the 1988 National Maternal Infant Health Survey (NMIHS) data.
