Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries

Seven days after mTBI, the blood vessels (stained in red) in the tissues around the brain are not completely repaired. A marker for intact vessels was used (labeled in green) to distinguish fully functional blood vessels (yellow) from ones that are still damaged (red).

Differences in blood gene expression among patients with varying COVID-19 severity

Infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19), but the clinical manifestations are highly variable. While some individuals remain asymptomatic, others manifest mild flu-like symptoms and some contract a severe life-threatening disease requiring mechanical ventilation and intensive care. There have been several deaths reported due to COVID-19. Why …

New study reveals signs of dementia are written in the blood

New study reveals signs of dementia are written in the blood

PCA of 33 AD or 6 selected dementia-related compounds showed significant differences between patients with dementia and HE subjects. Blood data of dementia and HE subjects were subjected to PCA. (A) A PCA plot using abundances of 33 (7 increased and 26 decreased) dementia-related compounds. Dementia and HE subjects were separated into two domains (see …
