Fat embolism syndrome: history, definition, epidemiology.

Abstract: The first clinical case of fat embolism was described over 100 years ago and significant progress has been made in the understanding of this condition since then. Gurd's criteria, consisting of major and minor clinical features, is the most commonly used diagnostic tool in the literature. Due to the lack of a gold standard for diagnosis, clinical criteria cannot be validated. It is now recognized that although fat embolization occurs in the majority of patients with long bone fractures, clinical signs and symptoms occur only in 1-10% of patients with fractures.

Ribosomal DNA Sequence Analysis of Isolates of the PKX Myxosporean and Their Relationship to Members of the Genus Sphaerospora

Abstract: The taxonomy of the PKX myxosporean, cause of proliferative kidney disease (PKD) of salmonids, has long been an enigma because only immature spores are consistently associated with the infection In the early 1990s, one of us (MLK) proposed that PKX may be the extrasporogonic form of Sphaerospora oncorhynchi, which has been observed in salmonids where PKD is enzootic Recently, the sequence of the small subunit ribosomal DNA (SSU rDNA) of PKX was deposited in GenBank (U70623) We designed PKX-specific primers by aligning this sequence with that of coho salmon Oncorhynchus kisutch and with those of other myxosporeans With these primers, a portion of the SSU rDNA of PKX was amplified and sequenced from the kidneys of infected salmonids from British Columbia, Washington, California, Newfoundland, and England The maximum variation in sequence across 764 base pairs (bp) among all PKX isolates, including the original sequence (GenBank U70623), was 08% Results indicated that PKX isolates from dif

Disruption of the Nitrogen Cycle in Acidified Lakes

Abstract: Experimental acidification of two small soft-water lakes caused nitrification to cease at pH values of 5.4 to 5.7. The resulting blockage of the nitrogen cycle caused a progressive accumulation of amnonium. When the epermental acidification of one of the lakes was ended and the pH was raised to 5.4, nitrification resumed after a time lag of 1 year.
