Is elevated level of lung protein an early predictor for COPD?

Researcher had previously discovered that the total mucin concentrations in the lungs are associated with COPD disease progression and could be used as diagnostic markers of chronic bronchitis, a hallmark condition for patients with COPD. They now report that one of these mucins, MUC5AC, is more closely and reliably associated with the development of COPD than is its brother, MUC5B. Source

Role of sleep-related brain activity in clearing toxic proteins and preventing Alzheimer’s disease

Evidence of sleep-dependent low-frequency (less than 0.1 Hz) global brain activity in the clearance of Alzheimer’s disease-related toxin buildup is presented in new research. This neuronal activity was more strongly linked with cerebrospinal fluid flow in healthy controls than higher risk groups and patients, and the findings could serve as a potential imaging marker for clinicians in evaluating patients.
