Lower phosphorus availability to plants and proximity to older forests indicated a higher species richness in forests on alluvial soil and of young age.
At heading stage onwards, lower carbon availability to the plant like shading reduces shoot dry matter and grain filling percentage of Nipponbare rice (Kobata et al. 2000) because sink capacity is already fixed.
The reactive iron oxide content in slag soil 4 was particularly high (18,759 μg/kg; Table 1), presumably leading to much lower As availability to colon microorganisms (0.3% bioaccessibility) and thus also limiting methylation.
In the case of iso-alkanes, biosurfactant-induced emulsions probably compensated the reduction of hydrocarbon solubility caused by methyl branching, which would have lowered substrate availability to cells.
Low transgene expression correlating with differences in codon bias has been hypothesised to be due to lower availability of specific tRNAs encoded by rare codons.
DNA fragmentation leads to a lower availability of intact target sequences compared to high quality genomic DNA such that, in a circulatory DNA sample, it may be no longer possible to determine the number of diploid or haploid genome equivalents from the detected number of target sequences.
Lower CRP use by females was related to lower availability of transportation services (36% without transportation service and 46% door-to-door services) and fewer caregivers accompanying the participants to CRP.
Trends were similar across studies with lower availability in government compared to mission or private facilities, in dispensary and health centres compared to hospitals, and in rural compared to urban facilities.
An example of quantitative analysis is generating surrogates for exposure and ADME behaviors based on chemical properties (e.g., predicted biological half-life may be used to extrapolate clearance rate, and a faster clearance rate could be interpreted as lower availability of the chemical to the molecular target).
The lower availability of resveratrol compared to DMU 212 may be the consequence of the high propensity of resveratrol to undergo conjugation reactions catalysed by enzymes (De Santi et al, 2000; Kuhnle et al, 2000; Marier et al, 2002), which are abundantly present in the gut (Eisenhofer et al, 1999).
