Disrupted circadian rhythms linked to later Parkinson's diagnoses

A study of 3,000 independently living older men found that weak or irregular circadian rhythms are associated with a greater likelihood of developing Parkinson's disease years later. The researchers suggest that these disruptions may reflect neurodegenerative processes already affecting the brain's internal clock.

Combination drug treatments for COVID-19 show promise in cell culture tests

A team of researchers found six existing antiviral drugs that worked against COVID-19 in laboratory tests, with a combination of nelfinavir and amodiaquine showing the highest synergy. However, using blood plasma from recovered patients to treat severely ill patients may only work if the donor has recently recovered from COVID-19.

How smooth muscle cells promote atherosclerosis

A study reveals that smooth muscle cells near necrotic cores of atherosclerotic plaques produce complement protein C3, stimulating macrophage activation and driving clonal expansion. The cells' ability to evade immune surveillance is restored by inhibiting CD47, suggesting these cells as viable therapeutic targets.
