The present study sought to define a possible role of phosphorus-stimulated ammoniagenesis, previously observed in vitro and in experimental animals, in the hypocalciuric effect of phosphorus in young men. It was hypo ...

RNA silencing plays a critical role in plant defense against viral infection. Plants use virusderived small interfering RNA to target and silence invading viruses. The antiviral silencing pathway can be broken down int ...

Bedrock groundwater dynamics in headwater catchments are poorly understood and poorly characterized. Direct hydrometric measurements have been limited due to the logistical challenges associated with drilling through h ...

Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic ...

The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes ...

Detailed upper ocean profiles of 234Th in dissolved (< 10,000 Daltons), colloidal (10,000 Da–O.45 μm), and particulate (>0.45 μm) forms were measured at a station (46º45′N, 126ºW) in the northeast Pacific Ocean. On ave ...
