Endothelial cell-derived RSPO3 activates Gαi1/3-Erk signaling and protects neurons from ischemia/reperfusion injury.

The current study explores the potential function and the underlying mechanisms of endothelial cell-derived R-spondin 3 (RSPO3) neuroprotection against ischemia/reperfusion-induced neuronal cell injury. In both neuronal cells (Neuro-2a) and primary murine cortical neurons, pretreatment with RSPO3 ameliorated oxygen and glucose deprivation (OGD)/re-oxygenation (OGD/R)-induced neuronal cell death and oxidative injury. In neurons RSPO3 activated the Akt, Erk and β-Catenin signaling cascade, but only Erk inhibitors reversed RSPO3-induced neuroprotection against OGD/R.

Role of hydrogen in traumatic brain injury: a narrative review.

Traumatic brain injury (TBI) is a serious global public health problem. Survivors of TBI often suffer from long-term disability, which puts a heavy burden on society and families. Unfortunately, up to now, there is no efficacious treatment for TBI patients in clinical practice.

Developmental Patterns of Fecal Bile Acids in Healthy Neonates and Children.

BACKGROUND Normal profiles of FBAs in healthy neonates and children in Kunming city and surrounding areas in China have not been previously determined. The objective of this study was to determine a developmental pattern of fecal bile acids (FBAs) in healthy neonates and children. MATERIAL AND METHODS A cross-sectional study was performed on 238 healthy neonates and children recruited in the First Affiliated Hospital of Kunming Medical University, China from October 2015 to September 2016.

[Levels of short-chain fatty acids in enterobacteria-related metabolites in the feces of infants with cholestatic hepatopathy].

Objective: To compare the levels of short-chain fatty acids in enterobacteria-related metabolites in feces between infants with cholestatic hepatopathy and healthy infants.

Methods: Thirty infants with cholestatic hepatopathy were enrolled in this study as the disease group, while 30 healthy infants were enrolled as the control group. Fecal specimens were collected from the disease group before and after treatment and from the control group.

Using drug-loaded pH-responsive poly(4-vinylpyridine) microspheres as a new strategy for intelligent controlling of Lactobacillus plantarum contamination in bioethanol fermentation.

Bioethanol fermentation is usually contaminated by bacteria, especially lactic acid bacteria (LAB), thereby leading to decrease of bioethanol yield and serious economic losses. Nisin is safer for controlling of bacterial contamination than antibiotics that are widely applied in industry. Moreover, in LAB contaminative bioethanol fermentation system, consistently decreased pH value provides opportunity to realize pH value responsive material-based release of anti-bacteria substances for intelligent and persistent controlling of bacterial contamination.

[Significance of detection of biomarker fecal bile acids in the diagnosis and treatment of childhood Henoch-Schönlein purpura].

Objective: To investigate the changes and clinical significance of biomarker fecal bile acids (BA) in children with Henoch-Schönlein purpura (HSP).

Methods: Nineteen children with HSP and twenty-seven healthy children were enrolled in this study. The stool samples were obtained at the acute and remission phases.

Perfusion-decellularized skeletal muscle as a three-dimensional scaffold with a vascular network template.

There exists a great need for repair grafts with similar volume to human skeletal muscle that can promote the innate ability of muscle to regenerate following volumetric muscle loss. Perfusion decellularization is an attractive technique for extracellular matrix (ECM) scaffold from intact mammalian organ or tissue which has been successfully used in tissue reconstruction. The perfusion-decellularization of skeletal muscle has been poorly assessed and characterized, but the bioactivity and functional capacity of the obtained perfusion skeletal muscle ECM (pM-ECM) to remodel in vivo is unknown.

The bioconcentration and degradation of nonylphenol and nonylphenol polyethoxylates by Chlorella vulgaris.

Nonylphenol polyethoxylates (NPnEOs), a major class of nonionic surfactants, can easily enter into aquatic environments through various pathways due to their wide applications, which leads to the extensive existence of their relative stable metabolites, namely nonylphenol (NP) and mono- to tri-ethoxylates. This study investigated the bioconcentration and degradation of NP and NPnEO oligomers (n = 1-12) by a green algae, Chlorella vulgaris. Experimental results showed that C.

LRP/amyloid beta-peptide interaction mediates differential brain efflux of Abeta isoforms.

LRP (low-density lipoprotein receptor-related protein) is linked to Alzheimer's disease (AD). Here, we report amyloid beta-peptide Abeta40 binds to immobilized LRP clusters II and IV with high affinity (Kd = 0.6-1.
