Of course, we don't know whether investment is at optimal levels; maybe R&D and CAPEX should be even higher.
For each additional metric that was at optimal levels, the risk of dementia fell by about 10%.
At the time of evaluation, only a few of these patients were at optimal levels of diastolic (27.4%) and systolic (43.0%) pressures.
Compounding the problem is the fact that building an airtight house in which air quality can be maintained at optimal levels is complex, with a perplexing array of equipment and construction techniques available.
Peronospora parasitica resistance genes (RPP) must be expressed at optimal levels to function against downy mildew in Arabidopsis[ 61], and specific profiles of grapevine RPP genes suggest fine tuning during T39-induced resistance.
Hence, to avoid the formation of volatile fatty acids and the phenomena of substrate inhibitions, the concentration of the substrate (glucose) in the liquid-phase must be maintained at optimal levels.
McCormack et al. also showed that when Perforin-2 is produced at optimal levels, cells are able to combat otherwise lethal, drug-resistant bacteria, including methicillin resistant Staphylococcus aureus (MRSA).
In the crop yield simulation, it was assumed that all other crop production inputs, including fertilizers and pesticides, were provided at optimal levels such that available water was the only constraint on crop production The economic module used crop yield outputs in combination with crop prices, crop production costs, and infrastructure costs to determine net revenue for each simulation year.
Postoperative outcomes may be improved if cardiac output and oxygen delivery are maintained at optimal levels.
A second issue is that some pathogens have evolved mechanisms to suppress Perforin-2 (see accompanying report by McCormack et al).. On the other hand, our data also shows that when Perforin-2 is expressed at optimal levels, highly pathogenic and antibiotic-resistant bacteria can be killed by Perforin-2.
