MetabolomicsSodium Butyrate mediates Histone Crotonylation and Alleviated Neonatal Rats Hypoxic-Ischemic Brain Injury Through Gut-Brain Axis (targeted SCFA brain metabolomics)

Neonatal hypoxic-ischemic encephalopathy (HIE) refers to nervous system damage caused by perinatal hypoxia, which is the major cause of long-term neuro-developmental disorders in surviving infants. However, the mechanisms still require further investigation. In this study, we found that the butan...

MetabolomicsTherapeutic Effect of Buyang Huanwu Decoction on the Gut Microbiota and Hippocampal Metabolism in a Rat Model of Cerebral Ischemia

Buyang Huanwu decoction (BHD) is a well-known Chinese herbal prescription. It has been widely used in the clinical treatment of cerebral ischemia (CI) in China. However, the mechanism underlying the treatment of CI with BHD remains to be elucidated. In this study, we combined microbiomic and meta...

TranscriptomicstRNA-Derived Small Non-Coding RNAs in Response to Ischemia Inhibit Angiogenesis
Ischemic injuries will lead to necrotic tissue damage, and post-ischemia angiogenesis plays critical roles in blood flow restoration and tissue recovery. Recently, several types of small RNAs have been reported to be involved in this process. In this study, we first generated a rat brain ischemic mo...

MetabolomicsIntraoperative intestinal ischemia-reperfusion injury aggravates postoperative delirium by remodeling gut microbiota
Postoperative delirium, is a notable and serious complication after surgery, commonly extending hospitalization by 2-3 days. In a cohort of 167 patients, elevated serum intestinal fatty acid binding protein (I-FABP) was identified as an independent risk factor for postoperative delirium. Complementa...

MetabolomicsSodium Butyrate mediates Histone Crotonylation and Alleviated Neonatal Rats Hypoxic-Ischemic Brain Injury Through Gut-Brain Axis (untargeted fecal metabolomics)

Neonatal hypoxic-ischemic encephalopathy (HIE) refers to nervous system damage caused by perinatal hypoxia, which is the major cause of long-term neuro-developmental disorders in surviving infants. However, the mechanisms still require further investigation. In this study, we found that the butan...

TranscriptomicsThe Peptide Semax Affects the Expression of Genes Related to the Immune and Vascular Systems in Rat Brain Focal Ischemia: Genome-wide Transcriptional Analysis
Our genome-wide study was designed to investigate the response of the transcriptome of ischemized rat brain cortex tissues to the action of neuropeptide drug Semax in vivo

MetabolomicsLocal and systemic metabolic alterations in brain, plasma, and liver of rats in response to aging and ischemic stroke, as detected by nuclear magnetic resonance (NMR) spectroscopy
Cerebral ischemia and aging induce local and systemic effects, and impact severity of stroke outcome. We performed comprehensive metabolic profiling to detect metabolites in brain, plasma, and liver as a function of aging and ischemia/reperfusion (IR). Ischemic stroke was induced by middle cerebral ...

TranscriptomicsGlobal transcriptomic profiling of ischemic/reperfusion injury in an in vivo wild-type mouse model.
Ischemic stroke triggers severe focal hypoperfusion accompanied with deprivation of oxygen and glucose to the cerebral tissue, together with loss of ATP, depolorization of neurons, elevated extracellular potassium concentration, and subsequently leads to excitotoxicity as well as increased oxidative...

TranscriptomicsPolysomal and total RNA in controls and after 10 min global brain ischemia and 8 hours of reperfusion
Complete global brain ischemia (CGBI) and reperfusion occur following resuscitation from cardiac arrest. Different brain neurons are selectively vulnerable to CGBI: pyramidal neurons of hippocampal CA3 survive 10 min CGBI but those of CA1 die at 3 days following 10 min CGBI. CA3 neurons are expecte...

TranscriptomicsMouse ischemic tolerance genomic analysis of the brain and blood.
Ischemic tolerance can be induced by numerous preconditioning stimuli, including various Toll-like receptor (TLR) ligands. We have shown previously that systemic administration of the TLR4 ligand, lipopolysaccharide (LPS) or the TLR9 ligand, unmethylated CpG ODNs prior to transient brain ischemia in...
