Numerous degenerative neurological conditions, most notably Parkinson's disease, have been linked to an excessive buildup of alpha synuclein (a-syn) in the brain. Intraneuronal inclusions, often known as Lewy bodies, are neuropathological characteristics seen in Parkinson's disease, Lewy body dementia, and other synucleopathies. The aggregation of a-syn is their main structural component. A-syn accumulation, aggregation, and ensuing Lewy body formation can be attributed to a variety of biological processes. These include genetic changes in parkin, synuclein, or the deubiquitinating enzyme ubiquitin C-terminal hydrolase (UCH-L1), which results in less efficient removal of a-syn via the ubiquitin proteasomal pathway (UPP). Additionally, environmental variables and an age-related decline in antioxidant defense mechanisms that heighten oxidative stress and can have an impact on the formation or clearance of a-syn are intracellular insults.
We focused on changes in the aggregation and clearance of a-syn as impacted by the UPP and the oxidative stress pathways in our dynamic models of a-syn processing in both normal and various disease states. A free radical profile similar to that observed in vivo after exposure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is produced during simulation of enhanced oxidative stress (MPTP). To replicate the kinetics of a-syn that correlates to the neuropathology reported for the sporadic and hereditary types of Parkinson's disease, different model parameters of oxidative stress, UPP failure, or both routes are used. With the use of this in silico model, it is possible to evaluate the kinetics of pathway elements and more accurately identify and validate key pharmaceutical targets.

Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
