Thioredoxin 1 regulates the pentose phosphate pathway via ATM phosphorylation after experimental subarachnoid hemorrhage in rats
Brain Res Bull. 2022 May 16;185:162-173. doi: 10.1016/j.brainresbull.2022.05.008. Online ahead of print.ABSTRACTSubarachnoid hemorrhage (SAH), a type of hemorrhagic stroke, is a neurological emergency with high morbidity and mortality. Early brain injury (EBI) after SAH is the leading cause of poor prognosis in SAH patients. TRX system is a NADPH-dependent antioxidant system which is composed of thioredoxin reductase (TRXR), thioredoxin (TRX). The pentose phosphate pathway (PPP), a pathway through which glucose can be metabolized, is a major source of NADPH. Thioredoxin 1 (TRX1) is a member of thioredoxin system mainly loc...

Low serum albumin: A neglected predictor in patients with cardiovascular disease
Eur J Intern Med. 2022 May 7:S0953-6205(22)00181-9. doi: 10.1016/j.ejim.2022.05.004. Online ahead of print.ABSTRACTAlbumin, the most abundant circulating protein in blood, is an essential protein which binds and transports various drugs and substances, maintains the oncotic pressure of blood and influences the physiological function of the circulatory system. Albumin also has anti-inflammatory, antioxidant, and antithrombotic properties. Evidence supports albumin's role as a strong predictor of cardiovascular (CV) risk in several patient groups. Its protective role extends to those with coronary artery disease, heart failu...

Comparison of Serum Selenium Levels Between Patients with Newly Diagnosed Atrial Fibrillation and Normal Controls
Biol Trace Elem Res. 2022 May 9. doi: 10.1007/s12011-022-03281-9. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common sustained dysrhythmia in the elderly population. It is estimated to affect more than 30 million people worldwide. AF occurs when abnormal electrical impulses start to activate in the atria and override the heart's natural pacemaker, which can no longer control the heart's rhythm. Since atrial contractility is impaired in AF, blood flow in the atria becomes stasis over time and causes thrombus formation. This thrombus causes the risk of embolism and causes complications such as stroke. ...

Carnosol suppresses microglia cell inflammation and apoptosis through PI3K/AKT/mTOR signaling pathway
This study aimed to explore the effects of carnosol on the oxygen-glucose deprivation (OGD) treated BV2 microglia cells. MTT and EdU assays were used to detect the cell viability and proliferation. Flow cytometry was conducted to measure the apoptosis rates. Additionally, the protein expression was determined by western blot. The inflammatory factors and antioxidant indexes were detected by corresponding kits. Carnosol promoted the proliferation and inhibited the apoptosis of the OGD treated BV2 cells. What's more, the protein expressions of PCNA and Bcl-2 were up-regulated, the Bax expression was down-regulated after carn...

Gut Flora Mediates the Rapid Tolerance of Electroacupuncture on Ischemic Stroke by Activating Melatonin Receptor through Regulating Indole-3-Propionic Acid
This study aimed to clarify the mechanisms of action of treatments of cerebral ischemic stroke from the perspective of gut microecology. We used a mouse model and cell cultures to investigate the effects of EA on the intestinal microflora in mice models of middle cerebral artery occlusion (MCAO) and the mechanisms underlying the antioxidant activities of metabolites. Fecal microbiota transplantation (FMT) was used to validate the roles of gut microbiota. Metabolomic analysis was performed to characterize the metabolic profile differences between the mice in the EA + MCAO and MCAO groups. Gavaging with feces relieved brain ...
