Newly recognized vital nitrogen cycle.
Soil and sea bacteria produce a small amount of nitrous oxide (N(2)O); a small part of this N(2)O is photochemically converted to nitric oxide (NO) in the stratosphere. This process has recently been shown to be the principal source of the active oxides of nitrogen (NO and NO(2)) in the stratosphere. The active oxides of nitrogen catalytically destroy ozone, and NO and NO(2) appear to be a prin...
متن کاملNewly-recognized Disorder of Protein Digestion
Enterokinase is an enzyme secreted by the mucosa of the small intestine and is responsible for the conversion of trypsinogen to its active product, trypsin. Its key role in initiating the formation of proteolytic enzymes from their inactive precursors is illustrated in Fig. 1. When the pancreatic zymogens reach the duodenum, trypsin is formed by the action of enterokinase on trypsinogen and thi...
متن کاملOnchocercosis: a newly recognized disease in dogs.
In the past 15 years, onchocercosis has been reported with increasing frequency in dogs in Europe and the United States, and 64 cases have been described so far. According to some authors, the Onchocerca sp. responsible for canine cases spills over from domestic or wild ungulates into dogs. However, canine Onchocerca does not match any of the descriptions for species of Onchocerca reported from...
متن کاملThe Global Nitrogen Cycle
The geobiology of nitrogen is dominated by large inert reservoirs and small biological fluxes. The largest reservoirs are nitrogen gas (in the atmosphere and dissolved in the ocean) and sedimentary nitrogen (sequestered in continental crust). Because most organisms cannot utilize gaseous nitrogen, we distinguish between fixed nitrogen compounds (which contain no N–N bonds) that are biologically...
متن کاملDetection of newly recognized rodent parvoviruses by PCR.
Several autonomous parvovirus isolates distinct from the prototypic rodent parvoviruses have recently been identified. These include variants of a mouse orphan parvovirus (MOPV) and a hamster isolate designated hamster orphan parvovirus (HOPV). In this study, a PCR primer set specific for these newly identified rodent parvoviruses was designed on the basis of DNA sequence comparisons of these i...
