Impact of Pre-Stroke Dementia or Mild Cognitive Impairment on Stroke Outcome: A Systematic Review and Meta-Analysis.

Background And Objective: Pre-stroke dementia (PSD) and pre-stroke mild cognitive impairment (PSMCI) are important risk factors for stroke. The present meta-analysis aimed to investigate the impact of PSD or PSMCI on stroke outcomes.

Methods: Electronic databases (PubMed, EMbase, Google Scholar, Cochrane Library, and TRIP) were screened for eligible studies published prior to March 31, 2021.

Hispidulin Protects Against Focal Cerebral Ischemia Reperfusion Injury in Rats.

Focal cerebral ischemia is associated with ischemia/reperfusion (I/R) injury. Hispidulin is a flavonoid compound with a variety of pharmacological properties. The neuroprotective effects of hispidulin have not been fully elucidated.

[Relationship between episodic memory and resting-state brain functional connectivity network in patients with Alzheimer's disease and mild cognition impairment].

Objective: To explore the relationship between the scores of episodic memory (EM) encoding and retrieving and the resting-state changes of brain functional connectivity (FC) network of Alzheimer's disease (AD) and mild cognition impairment (MCI) patients.

Methods: All subjects were recruited from special care clinic and ward and health physical examination center, Qingdao Huanxiu Community and Affiliated Hospital, Medical College of Qingdao university from January 2009 to July 2012.They were divided into AD group (n = 16), MCI group (n = 24) and normal control (NC) group (n = 24).

Composite films of lecithin and heme proteins with electrochemical and electrocatalytic activities.

Functional composite films made from lecithin micelles and the two heme proteins of met-myoglobin (Mb) and met-hemoglobin (Hb) are reported in this paper. Proteins in functional composite films have much higher rates of electron transfer than proteins in solutions on carbon paste (CP) electrodes. Cyclic voltammograms (CVs) all give a pair of well-defined and quasi-reversible peaks, corresponding to the heme FeIII/FeII redox couple of proteins.
