The human Tar-DNA binding protein, TDP-43, is associated with amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders.
There are several considerations that need to be taken into account to explain the limited concordance between human and porcine TARs.
TAMPA, Fla., Aug. 19 - There are skinless cadavers sliced in two, tarred human lungs in glass cases, dehydrated brains you can touch.
Human exposure to coal tars can be through inhalation, ingestion, and absorption through the skin.
"Maíria's story is quite simply horrific and once again exposes the true nature of the Provisional IRA, an organisation that claimed to protect the community, while subjecting citizens to all manner of human rights abuses, from tarring and feathering, through kneecapping and sexual abuse to abduction, torture and murder".
The discovery of these TARs, in humans, requires population sizes of tens or even hundreds of thousands of individuals that are unavailable in non-model organisms as pigs.
Coal-tar-based sealcoat products, widely used in the central and eastern U.S. on parking lots, driveways, and even playgrounds, are typically 20−35% coal-tar pitch, a known human carcinogen that contains about 200 polycyclic aromatic hydrocarbon (PAH) compounds.
Asphalt is one concern, as it contains coal tar pitch, a recognized human carcinogen, as well as polycyclic aromatic hydrocarbons (PAHs) including benzo[ a]pyrene, another carcinogen.
Yet, the ultimate reason why the caribou are on the way out is because multiple human disturbances – most pressingly, the tar sands development – have altered their habitat into a landscape that can no longer provide the food, cover and security they need.
