While age is the greatest risk factor, AD is not part of normal aging, which highlights the importance of research on how the brain changes normally with age and the differences between "normal aging" and "abnormal aging." While the definitive diagnosis of AD is based on postmortem pathology...
Large-Scale ADC Histogram Analysis of the Brain Aging: Normal versus Abnormal (667 subjects, 2 days-93.8 years) Background/Purpose: The quantitative assessment of apparent diffusion coefficient (ADC) in normal aging and in various diseases have been reported by many ... M Watanabe,N Ward,A Oz...
No significant changes in LVEF occurred during dobutamine (60 +/- 6% vs. 61 +/- 10%, p = NS), whereas PESP significantly increased LVEF (60 +/- 6% vs. 74 +/- 6%, p < 0.001); PESP at peak handgrip normalized the abnormal LVEF (42 +/- 7% vs, 72 +/- 5%, p < 0.001);...
After adolescence, a medically normal heart rate for any age adult is anywhere between 60 and 100 bpm. Most healthy adults have a heart rate of 55-85 bpm. What's an unhealthy heart rate? Trained athletes can have very low heart rates, and children typically have higher ones. If you are...
One is, less stable IL-6 leading to reduced signaling events and the other one, increased levels of IL-6 leading to abnormal/dysregulated angiogenesis. In a study it was shown that this polymorphism (SNP) in IL6 is not associated with circulating IL-6 levels [121]. Another possibility is...

Clinical progression was found to be faster in individuals with both abnormal amyloid and tau levels (A+ T+) than in individuals with isolated amyloidosis (A+ T-) [38, 41]. It is likely that, in our study, the classification according to the data-driven thresholds grouped individuals ...
The positive value of PAS indicates abnormal activation of a signaling pathway, and the negative value - its repression. Here, the case-to-normal ratio, CNRn, is the ratio of expression levels for a gene n in the sample under investigation to the same average value for the control group ...
meningioma brain tumors16, compared to non-pathological tissue, were shown to contain a higher concentration of ferrimagnetic particles and abnormal expression of iron-related genes17,18. These findings suggest there are detectable differences in iron homeostasis between brain tumors and normal brain tis...
, suggesting that these counters yield more accurate mitotic age estimates during normal/healthy aging compared to those based on hypomethylation. To explore the effect of CTH and the additional caveat that RepliTali is EPIC-based and thus less likely to perform well on 450k datasets, we ...
