Notch and Shh signaling activities during tumor onset were different between MDB and pancreatic adenocarcinoma, indicating a tissue-specific regulation of cell signaling pathways.
Another possible factor could be that symptoms at MPM onset are different in black compared to white patients, as previously reported in lung cancer [ 8], and this could cause delay in diagnosis.
In the hypertensive subgroup PWV, but not DRIN, was higher at baseline in those developing microalbuminuria, confirming previous cross-sectional observations [ 34, 35] and suggesting that mechanisms responsible for its onset are different for hypertension or type 2 diabetes [ 36].
Because age at onset was different among sCJD patients (mean ± SD, 67.7 ± 9.5 years) and controls (59.3 ± 16.6 years) (p<0.0001), we divided the sCJD patients and controls into 3 categories according to age at disease onset; 31 50 years, 51 70 years, and >71 years.
However, as discussed below, we have indications that the origin of the locking to saccade-onset is different for the 2 signals.
They found evidence that the pre-onset auroral sequence is different from what has been generally considered previously, being initiated by an intensification along the poleward boundary of the auroral oval (a PBI) that is followed by a discrete auroral form that traverses magnetic latitude lines to lower latitudes.
Based on these empirical observations, Carter and Cavanagh have proposed that the percept sequence and the percept duration are fundamentally different (i.e., the perception at rivalry onset is fundamentally different from the perception during prolonged rivalry [18]).
The concordance of lupus in identical twins is often incomplete, and when concordant, the age of onset is usually different.
However, we should note that the age at onset is noticeably different between the affected father and the proband in this family (54 years in the father and 38 years in the proband).
A compelling reason to investigate sex differences in the brain is that for almost all neuropsychiatric illnesses the onset, prevalence, and symptomatology is different between males and females.
Lead-time bias is the bias that may occur when outcomes are compared, but where the onset of measuring 'delay' is different as a result of diagnosis earlier in the natural history of the cancer, but that will have no effect on the outcome.
