Exposure to Contaminated River Water is Associated with Early Hatching and Dysregulation of Gene Expression in Early Life Stages of the Endangered Copper Redhorse (Moxostoma hubbsi).

The copper redhorse (Moxostoma hubbsi) is an endangered fish that spawns exclusively in the Richelieu River (Quebec, Canada). Tributaries of the Richelieu are contaminated with high levels of current-use pesticides, which may impact early-life stage (ELS) copper redhorse and other native fishes. We assessed the effects of exposure to contaminated river water on ELS copper redhorse and river redhorse (Moxostoma carinatum), a related fish that shares the copper redhorse's spawning grounds and nursery habitat.

Phylogeographic inferences from chloroplast DNA: quantifying the effects of mutations in repetitive and non-repetitive sequences.

Phylogeographic inference can be a powerful tool in reconstructing species' evolutionary histories; however, although inferred phylogeographic patterns should depend in part on the underlying types and rates of mutations, the effects of different types of mutations have seldom been quantified. In this study we identified two chloroplast minisatellites in the common reed Phragmites australis, and showed that these are more variable than chloroplast microsatellites. We then recreated parsimony networks of the global phylogeography of P.

Clinical reassessment of malignant hyperthermia in Abitibi-Témiscamingue.

Purpose: In 1992, 1812 individuals (1.2% of the population) were labelled at risk for malignant hyperthermia (MH) in seven families from Abitibi-Témiscamingue. To evaluate the effective risk in this population, a multidisciplinary study was undertaken which included clinical, genealogical and molecular aspects.

Discrepancy in the evaluation of visual impairment of elderly low-vision patients by general eye care practitioners and by low-vision practitioners.

Levels of impairment and disability determine eligibility for different welfare programs for visually handicapped persons. General eye care practitioners have to determine the level of impairment for administrative purposes, whereas the low-vision practitioner measures the level of impairment in order to plan the rehabilitation program. We compared the severity of visual impairment reported by the referring practitioners and the one reported by the low-vision specialists for the population of elderly low-vision patients receiving care from one of the largest rehabilitation centers for the visually handicapped in Quebec.
