THROMBOSIS OF THE CEREBRAL VEINS AND SINUSES

open access: yes, 2022
Cerebral venous thrombosis (CVT) is rare, but more common than we think. The actual incidence of CVT remains unknown to date, and the available data (3-4 cases per 1 million population per year in adults and 7 cases per 1 million population in children) are based on the number of hospitalizations of patients with CVT in large hospitals.

Senkyunolide I Improves Septicemia‐Induced Brain Dysfunction via Regulating Nrf2 and Astrocyte Activity.

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Senkyunolide I (Sen I) has a protective effect on the blood–brain barrier (BBB) in rats with sepsis‐associated encephalopathy (SAE). This study investigated whether Sen I regulates Nrf2 to ameliorate sepsis‐induced brain dysfunction (SIBD). Sixty rats were randomly assigned into Sham group, SAE group (Model group), SAE + Sen I group (72 mg/kg,
