The phrase "ascertain if changes in" is correct and usable in written English.
It can be used when you want to determine whether there are any modifications or variations in a particular context or subject.
Example: "The researchers aim to ascertain if changes in temperature affect the growth rate of the plants."
Alternatives: "determine whether changes in" or "find out if changes in".
Under the experimental conditions used in the present study, it is not possible to ascertain if changes in specific binding relate to alterations in affinity (Kd) and/or maximal binding capacity (Bmax).
The use of positive affect scores from PANAS was to ascertain if changes in positive mood occur that may not be so clearly identified using POMS.
Though a limitation of our study is that we can not ascertain if changes in NRG1 isoforms are necessary or sufficient to contribute to DPN, altered signaling through the NRG1-Erb B2 ligand/receptor pair may contribute to dysfunction of both myelinated and unmyelinated fibers since diabetic mice treated with erlotinib exhibited an improvement in both mechanical and thermal sensitivity.
Urinary polyamine (UPA) excretion patterns were measured in 39 patients with clinically evaluable epithelial ovarian cancer immediately before they were treated with a cycle of chemotherapy and 24-48 h after chemotherapy to ascertain if changes in UPA excretion patterns correlated with eventual response to treatment.
In all cases, flies were placed on the training regimen at three-four days of age, and trained for three weeks, then taken off the training for two more weeks, in order to ascertain if changes to climbing ability would persist after cessation of training.
In order to ascertain if changes at the level of steady-state mRNA are mirrored at the protein level, we performed western blots on the conditioned medium of SW1353 cells at a 24-hour time point.
To ascertain if gross changes in protein expression would be visible between cells grown aerobically and anaerobically, protein extracts were resolved further using a new, rapid high resolution protein separation technology based upon capillary electrophoresis (deltaDOT) and conventional SDS-PAGE (see Figure 3).
We could not ascertain if the change in sleep architecture in animals treated with high dose (50 mg/kg) of amiloride was indeed due to the direct action of the drug or because of an associated acute stress induced in response to the drug.
We wanted to ascertain if the changes observed in the PRCs were due to the cholinergic down-regulation of slow voltage-dependent potassium currents and not due to changes in the stimulus amplitude.
Study 1 aims to objectively ascertain if neurophysiological changes occur in the functional brain areas associated with pain catastrophizing, when catastrophizing FMS subjects are exposed to visuals of exercise activities.
Such changes must be further studied at the protein level to ascertain if the observed changes in mRNA translation patterns are biologically relevant.
