Erythrocyte sedimentation rate/zeta sedimentation rate.

Sedimentation rates are a vital laboratory adjunct to the clinical skills of the emergency physician. A patient with an elevated rate in the emergency department needs further evaluation and appropriate referral. If the test is markedly elevated, there is a 95 per cent chance of an infectious, inflammatory, or neoplastic process as the underlying cause.

The micro-erythrocyte sedimentation rate in black neonates and children. Part II. A comparative study of the micro-erythrocyte sedimentation rate, C-reactive protein test and total white cell count.

The value of determination of the micro-erythrocyte sedimentation rate (ESR), testing for the presence of serum C-reactive protein (CRP) and the total white cell count (WCC) has been assessed in neonates and children, both healthy and in disease states. The results show that collective and maximum use of all three investigations aids diagnosis because these tests are simple, quick, cheap and easy to perform. Furthermore, the study has demonstrated that compared with a high ESR and WCC, the presence of CRP was the best single indicator of infection. The CRP test has the greatest predictive value and sensitivity in that it indicates the intensity of an infection as well as the patient's response to therapy.

Concentration and mobilization of Cd, Cu, Pb and Zn by meiofauna populations living in harbour sediment: their role in the heavy metal flux from sediment to food web.

The bioavailability of Cd, Cu, Pb and Zn was assessed in different harbours of the Atlantic coast (France). The responses of the two dominant meiobenthic groups (nematodes and copepods) to a heavy metal contamination gradient measured in similar subtidal sediments were observed in field surveys. Heavy metal concentrations were measured in nematodes and copepods. Nematodes have higher Cd, Cu, Pb and Zn transfer factors than copepods or other benthic species. The flux of heavy metal through nematodes was estimated and appears to be important compared to plankton in the process of heavy metal transfer to benthic or pelagic food webs.

Ammonium production in sediments inhibited with molybdate: implications for the sources of ammonium in anoxic marine sediments.

Ammonium production in the presence of specific inhibitors of sulfate reduction and methanogenesis was investigated in six marine sediments which differed in bulk properties and organic matter input. In all cases, little effect of the inhibitors on ammonium production was observed, although sulfate reduction was suppressed by molybdate. This gives evidence that the processes of fermentation and hydrolysis are of primary importance in ammonium generation at the sites studied. Although sulfate reduction rates may appear to be coupled to ammonium production rates, sulfate reduction does not necessarily contribute directly to generation of ammonium in marine environments.
