Studying the winter ecology of freshwater fishes has been a focus of much past and present research. Because of obvious constraints with studying fish in situ during the winter, few studies have made links between laboratory ...

Several genes involved in the regulation of apoptosis can influence longevity. Although observations in several different systems imply that apoptosis and aging are closely linked, the relationship between the two remains ...

The Cataraqui River, which drains 930 square km of watershed before emptying into the inner harbour of Kingston, Ontario (pop: 113,000), has a long history of anthropogenic use. More than 40 industries have existed within ...

Two common strategies used to identify specific genes that influence aging in Drosophila melanogaster are overexpression screens and candidate gene approaches. Both of these strategies rely on gene expression systems. A ...

Aging, characterized by a time-dependent functional decline, eventually results in the death of an organism. Unfortunately, this complex biological phenomenon is poorly understood. In order to dissect the molecular changes ...

Allatostatins (ASTs) are neuropeptides that inhibit the biosynthesis and release of juvenile hormone from the corpora allata (CA) of various insects including the cockroach Diploptera punctata. We hypothesized that a similar ...

In multicellular organisms, apoptosis plays an important role in maintaining cellular homeostasis and removing damaged cells that present a threat to the integrity of the organism. Several lines of evidence suggest that ...

Arsenic taken up by plants and fungi from contaminated soils can subsequently be introduced into food chains. Given the toxic properties of some arsenic compounds, this may be a cause for concern. Much remains to be learned ...

Monocarboxylate transporters (MCTs) have been shown to be important in regulating metabolism during hypoxia in mammals. However, the role of MCTs in hypoxic survival in lower vertebrates is currently unclear. The goal ...

Migratory birds spend most of the year on the over-wintering grounds or traveling between breeding and wintering areas, but research has focused on the relatively short breeding period. As a consequence, we have only a ...
