However, there are too few onshore outcrops in which each tephra is exposed to determine source areas from onshore data like composition, grain size, and bed thickness.
In some experiments, the undamaged contralateral sciatic nerves were exposed to determine the threshold for muscle contraction.
They found nothing significant in the soil or the vegetation the antelopes had been exposed to, and determined that the animals were not nutritionally deficient or immunosuppressed.
"If somebody had a pre-existing condition or had been taking prescription drugs or illicit drugs, it is exponentially difficult to pull apart all of the substances and compounds they had been exposed to and determine what is actually responsible for that person's death," he said.
The general latitude frequented by the whales a reflection of where the whales were likely to have been exposed to pollution was determined by analyzing carbon isotope ratios.
Thus, functional precision therapy approaches where the primary tumor tissue is directly exposed to drugs, to determine which may be efficacious, have the potential to boost personalized medicine efforts and influence clinical decisions3,4.
HMEC that express p16INK4A and vHMEC that do not, were transduced with constitutively active Ha-rasV12 and subsequently exposed to serum to determine whether signals from the cellular microenvironment could cooperate with ras to promote the malignant transformation of vHMEC.
For these reasons, this study addressed the transcription analysis of hENT1, dCK, RRM1, and RRM2 in parental cell lines and in isolated variable resistant subclones continuously exposed to gemcitabine to determine possible predictive markers for gemcitabine resistance.
Cytoprotective dose of neferine in muscle cells (Rhabdomyosarcoma cells) exposed to hypoxia was determined by MTT assay.
The generation of free hydroxyl radicals in the brains of animals exposed to hypoxia was determined in a second experiment.
