When it comes to studying nutrition, this sort of extensive, long-term clinical trial is supposed to be the gold standard.
In the extreme situation of extensive long-term anaesthesia (after 24 h), the risk for oxygen toxicity (muscle fasciculation, convulsion) is increased, and in this case, the inspired oxygen should be kept below 40%.
Other limitations include using a smaller sample sizes and a lack of extensive long-term follow-up information.
However, the microarray results were supported by the analyses of the effects of extensive long-term ex vivo cultivation of MSC on their proliferation capacity, their morphology, surface marker profile, and differentiation ability.
Extensive, long term usage of microarray gene expression assays in clinical studies has produced a vast repository of extremely valuable, well-designed datasets.
This sort of bill is essential for a company like Monsanto that performs all of their own safety testing, and has never conducted extensive long term studies related to the possible long term side effects of their genetically engineered products.
On the other hand, extensive long term aging effects were measured in case of WMA mixtures.
Visual expertise, or the extraordinary capability to discriminate fine differences among a group of similar object images, develops through extensive long-term training, and it is specific to the domain of stimuli used in the training.
This has been facilitated by extensive long-term research of the resident population, which includes an occasional health assessment programme [ 10].
Scientists agree that extensive long-term use of Bt crops and glyphosate and gluphosinate, the herbicides associated with HT crops, can promote the development of resistant insect pests and weeds (ICSU, GM Science Review Panel).
Visual expertise in discriminating fine differences among a group of similar objects can be obtained through extensive long-term training.
