A study found that errors in cancer diagnosis were relatively frequent and institution-dependent, with gynecologic errors resulting in harm in 45% of cases. The majority of errors were caused by sub-optimal specimen collection, while pathologist misinterpretation ranged from 5-50%.
Researchers found that the protein Klotho extends lifespan in mice by making them resistant to insulin, but also increases risk of diabetes. The study offers promising hope for developing anti-aging therapies.
The study found that gamblers and alcoholics have unique personality traits affecting their cravings, with gambling craving linked to positive emotions and alcohol craving tied to negative emotions. The research suggests that individuals with distinct emotional regulation patterns are more vulnerable to addiction.
Researchers created transgenic mice overproducing Ab40 and Ab42 to study their roles in AD pathology. The results showed that Ab42 mice accumulated extensive amyloid plaque and neural damage, while Ab40 mice showed little disease pathology. The study provides evidence for the critical role of Ab42 in initiating amyloid deposition.
A team of researchers from Case Western Reserve University propose an alternate view on the pathology of Alzheimer's disease (AD), suggesting that neurofibrillary tangles (NFTs) may be protective against oxidative stress. NFT-bearing neurons can survive for decades, and their presence may be a response to reduce oxidative damage.
