Is it possible that newborn and adult skin (perhaps based on the anatomy or level of cellular differentiation) respond differently to UV exposure that could explain the disparate results?
Until now, no reliable CT morphologic criteria have allowed interim differentiation between responding and non-responding tumours.
This homogeneity of SUV change in response to NAC demonstrates the difficulty in the differentiation of responding and non-responding patients.
Recent studies have indicated that cell development or differentiation responds to changes in the stiffness of the microenvironment [ 22, 24– 26].
The initial field may be set up by a number of diffusing molecules such as morphogens that allow regionalization to occur, from which cellular differentiation responds along a gradient [ 5, 18], probably by means of a reaction-diffusion-type mechanism [ 19, 20].
Preexposure to stimulus X retarded subsequent differentiation of responding to reinforced A trials and non-reinforced AX trials, suggesting that CS-preexposure retarded development of inhibitory conditioning.
We observed that, in contrast to induction of antiviral CD8+ T cell responses and vigorous effector CD8+ T cell responses in secondary lymphoid tissues such as lymph nodes and spleen by SubQ or IN virus delivery, induction of CD8+ T cell responses in the liver results in a defect in the differentiation of responding CD8+ T cells into pro-inflammatory cytokine producing cytolytic effector T cells.
Analysis of response rates under the two schedules indicated that, as expected, the temporal differentiation of responding seen in the rats trained under the FIPP was absent in the rats trained under the VI schedule.
The purpose of the yoked VI procedure was to provide a control group that was exposed to a schedule that did not entail temporal differentiation of responding, yet was well matched to the FOPP in terms of non-temporal variables such as food deprivation level, switching between operanda, reinforcement rate and overall response rate.
The marketing strategy Tran found to be most successful was a relentless focus on the differentiation to respond to consumer desires.
