Gender-specific lncRNA-miRNA-mRNA regulatory network to reveal potential genes for primary open-angle glaucoma.

Background: Investigation of biomarkers may facilitate understanding the mechanisms of primary open-angle glaucoma (POAG) and developing therapeutic targets. This study aimed to identify potential genes based on competing endogenous RNA (ceRNA) network for POAG.

Methods: Based on long noncoding RNAs (lncRNAs), microRNAs (miRNAs) and messenger RNAs (mRNAs) from the Gene Expression Omnibus (GEO) database, we identified differential expressed lncRNAs (DELs), differential expressed miRNAs (DEMis) and differential expressed mRNAs (DEMs) and then constructed a ceRNA network.

Anticoagulant-active sulfated arabinogalactan from Chaetomorpha linum: Structural characterization and action on coagulation factors.

A sulfated polysaccharide from the green alga Chaetomorpha linum, designated CLS4, was isolated by water extraction, anion-exchange and size-exclusion chromatography. Chemical and spectroscopic analyses demonstrated that CLS4 was a sulfated arabinogalactan, which was constituted by (1→6)-β-d-galactopyranose and (1→5)-α-l-arabinofuranose residues with sulfate groups at C-2/ C-3 of (1→5)-α-l-arabinofuranose and C-2/C-4 of (1→6)-β-d-galactopyranose. CLS4 possessed strong anticoagulant activity in vitro or in vivo as evaluated by activated partial thromboplastin time and thrombin time assays.

Effects of cyclopeptide C*HSDGIC* from the cyclization of PACAP (1-5) on the proliferation and UVB-induced apoptosis of the retinal ganglion cell line RGC-5.

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide that confers potent neurotrophic and neuroprotective effects. Cyclopeptide C*HSDGIC* (CHC), which results from the cyclization of PACAP (1-5) with disulfide, has been demonstrated to represent a potent agonist for the PACAP-specific receptor PAC1 which mediates the majority of PACAP's effects. In this study, the expression of PAC1 in a rat retinal ganglion cell line (RGC-5) was confirmed using a western blot analysis, and it was determined that CHC promoted the proliferation of RGC-5 cells using the cell counting kit-8 (CCK8) assay and flow cytometry.

Endogenous aspergillus endophthalmitis after kidney transplantation.

Endogenous aspergillus endophthalmitis(EAE) after kidney transplant is a rare but important clinical problem due to potentially devastating consequences. Early diagnosis of EAE, timely removal of affected vitreous by vitrectomy, proper anti-fungal treatment, all contributed to the successful control of the disease. Therapeutic success of EAE in post-transplant patients depends largely on prompt diagnosis.
