Has been evaluated in several validation studies with mixed results.
The same findings were confirmed by previous studies with mixed culture of organisms which revealed high degradative activity than with single cultures of microorganisms (Chigusa et al. 1996; Benka-coker and Ekundayo 1997 and Wakelin and Forster 1997).
The treatability studies with mixed consortia revealed that the acclimatized bacteria were highly effective in treating the waste by achieving a maximum reduction of 86.6% from as high as 4000 mg/l COD concentration.
Positive fluid balance was also identified as an independent risk factor for IAH in several studies [4, 12, 13], whereas some other studies with mixed ICU patients failed to observe positive fluid balance as an independent risk factor for IAH [3, 15].
Although studies on H2 oxidation coupled to ferric iron reduction by Escherichia coli suggested that NR stimulated both H2 and formate oxidation (McKinlay and Zeikus 2004), NR addition resulted in accumulation of both H2 and formate in our studies with mixed ruminal microbes.
However, further studies, with mixed primary cultures and in vivo systems, will be useful to corroborate these results which, anyway, are consistent with previous observations.
Since both UniGene and RefSeq are billed as non-redundant sets of transcript IDs, and have been used in prior studies with mixed results, it is still unclear as to which approach is better.
Interestingly, studies with mixed funding were of the highest quality.
There were in vitro studies with mixed results on the effects of testosterone on OPG expression.
In studies with mixed surgical procedures there had to be a defined prostatectomy subgroup.
Also, prospective studies with mixed samples have been almost entirely negative [ 23, 40].
