ation by suppressing VCAM-1, MCP-1, and SR-A expression, as well as NF-κB activity, possibly through Nrf2 inhibition. The involvement of Nrf2 for MA-mediated anti-inflammatory effects however differs between HUVECs and macrophages. Future investigations are warranted for a detailed evaluation of the contributing roles of Nrf2 in foam cells formation.

Patients with acute kidney injury (AKI) have higher mortality, and sepsis is among its main causes. DX600 research buy MicroRNAs (miRNAs) are essential for regulating kidney function and could have curative potential. This study explored the possibility to treat AKI with miR-125a-5p and reveal the possible mechanism.

LPS-induced mouse model and LPS-induced RAW264.7 cell model of AKI were established and treated with miR-125a-5p mimics or inhibitors. Serum creatinine and blood urea were measured to evaluate kidney function. The pathological changes of kidney tissues were detected by H&E and PAS staining technique, and the infiltration of macrophages were observed by immunohistochemistry. RAW264.7 cell viability, TRAF6 and cytokines expressions under LPS stimulation were measured. The role and therapeutic potential of miR-125a-5p were verified in vivo and in vitro after given miR-125a-5p mimics or inhibitors.

LPS-induced mice had increasing serum creatinine and urea, and evident pathological changes, including severe tubular dilatation and macrophages infiltration. TRAF6 expression in the kidney was significantly higher, while miR-125a-5p expression was suppressed. MiR-125a-5p targeted TRAF6, and its overexpression deactivated NF-κB signaling pathway, reducing downstream TNF-α, IL-1β and IL-6 expressions. MiR-125a-5p mimics rescued LPS-induced kidney damage and suppressed pro-inflammatory cytokines expression through inhibiting TRAF6/NF-κB axis.

We highlighted that miR-125a-5p could inhibit LPS-induced acute inflammation in the kidney through targeting TRAF6/NF-κB axis. These results might contribute to the development of molecular therapy in AKI.

Effective non-invasive therapies for DM are still lacking. Here, we have developed Microcurrent electrical nerve stimulation (MENS), a non-invasive therapy, and tested on 46 mice clustered into five groups, such as control, STZ-induced DM, and MENS treatment groups. Experimental results show that MENS treatment is able to improve seven biochemical indexes (e.g., hemoglobin A1c and glucose level). To investigate the mechanisms of MENS treatment on STZ-induced DM, we selected six representative samples to perform microarray experiments for several groups and developed an integrated Hierarchical System Biology Model (HiSBiM) to analyze these omics data. The results indicate that MENS can affect fatty acid metabolism pathways, peroxisome proliferator-activated receptor (PPAR) signaling pathway and cell cycle. Additionally, the DM biochemical indexes and omics data profiles of MENS treatment were found to be consistent. We then compared the therapeutic effects of MENS with anti-diabetic compounds (e.g., quercetin, metformin, and rosiglitazone), using the HiSBiM four-level biological functions and processes of multiple omics data. The results show MENS and these anti-diabetic compounds have similar effect pathways highly correlated to the diabetes processes, such as the PPAR signaling pathway, bile secretion, and insulin signaling pathways. We believe that MENS is an effective and non-invasive therapy for DM and our HiSBiM is an useful method for investigating multiple omics data.Myocarditis is an inflammatory condition of the myocardium and is usually categorised as acute nonfulminant and acute fulminant myocarditis. Myocardial injury can result via viral infections, direct injury or immune responses. Fulminant myocarditis can be characterised by severe and sudden cardiac inflammation that may result from cardiogenic shock, ventricular arrhythmias or multi-organ system failure. Extracorporeal membrane oxygenation (ECMO), also known as extracorporeal life support, is an effective technique for patients with fulminant myocarditis, providing heart and lung support and adequate gas exchange or perfusion to sustain life. Essentially, ECMO pumps blood out of the body to an oxygenator that acts as an artificial lung, which adds oxygen to the blood and removes carbon dioxide. This report aims to review recent advances in ECMO and relate case studies of fulminant myocarditis patients. The types of ECMO, predictive factors for success, clinical studies and recent technological advances in the field will be discussed.

The purpose of this study was to determine the rate of unplanned returns to the operating room (OR) within 180 days and at any time postoperatively after valved and non-valved tube shunt surgery.

Retrospective case-control study.

A review of 357 eyes that underwent tube shunt surgery (151 valved, 206 non-valved) was conducted at an academic glaucoma service between January 2014 and December 2016. A control eye was time matched for each eye that underwent reoperation.

The reoperation rate within 180 days was 16 of 151 (10.6%) for valved and 25 of 206 (12.1%) for non-valved tube shunts and at any time postoperatively was 31 of 151 (20.5%) for valved, and 47 of 206 (22.8%) for non-valved tube shunts. Mean postoperative follow-up was 2.8 ± 1.1 years. The most common reoperations within 180 days and at any time postoperatively after valved tube shunt surgery were tube revisions (43.8% within 180 days, 38.7% any time) and external cyclophotocoagulation (CPC) (31.3% within 180 days, 38.7% anytime). The most n valved and non-valved tube shunts.

The purpose of this study was to investigate the association between the vertical position of the central retinal vessel (CRV) within the optic nerve head (ONH) and the site of visual field defects (VFDs) in glaucoma.

Cross-sectional study.

The vertical position of the CRV was identified in 134 glaucoma eyes and 61 normal eyes at the point at which CRV exited the lamina cribrosa (LC) onto the ONH surface, by using spectral-domain optical coherence tomography (exit position). The position was also identified at the entry point into the LC from the retrolaminar ONH region (entry position), which was little influenced by glaucomatous LC deformation, therefore close to the original position before the glaucoma development. Positions were compared among glaucoma eyes with different sites of VFDs, and between glaucoma and normal eyes.

In glaucoma eyes, the entry position of the CRV was in the superior ONH region in 63.0% of eyes with superior VFDs and in the inferior ONH region in 97.8% of eyes with inferior VFDs (P < .0001). The exit position exhibited a similar percentage. The vertical CRV positions were not significantly different between glaucoma and normal eyes, both at the entry and exit positions.

Eyes with CRVs in the superior ONH region were significantly more likely to form VFDs in the superior hemifields and vice versa. The vertical position of the CRV was little altered by the development of glaucoma. The original position of the CRV before the development of glaucoma may influence regional susceptibility to glaucomatous stress and may be useful in predicting initial sites of VFDs.

To identify sociodemographic factors and comorbid conditions associated with receiving keratoplasty for keratoconus (KCN) DESIGN Retrospective, cross-sectional study METHODS Health records of KCN patients aged <65 years from 2011 to 2018 were obtained from the IBM MarketScan Database. A multivariable model adjusted for potential confounders was used to examine factors associated with the risk of receiving keratoplasty.

Of 42,086 total KCN patients identified, 1,282 (3.0%) patients had keratoplasty to treat KCN. In the fully adjusted analysis, female sex (OR=0.87 [95% CI=0.78-0.98]) and living in metropolitan areas (OR=0.75 [0.63-0.90]) were associated with lower odds of receiving keratoplasty. Compared to individuals aged 10-19 years, those aged 20-29 (OR=1.77 [1.31-2.41]) and 30-39 (OR=1.61 [1.19-2.17]) were more likely to have keratoplasty, while individuals in the older age groups (50-64) did not show statistically significant associations. Conditions associated with higher odds of receiving keratope frequent follow-up and/or early crosslinking to reduce the need for subsequent keratoplasty.

To report the anterior segment clinical features as well as histopathologic and histochemical characteristics of corneal findings associated with the largest reported cohort of patients with Hurler Syndrome and other variants of mucopolysaccharidosis (MPS) I undergoing corneal transplantation.

Retrospective observational case series.

SETTING Institutional PATIENT OR STUDY POPULATION 15 corneas from 9 patients with MPS-I spectrum disease who underwent corneal transplant to treat corneal clouding between May 2011 and October 2020.

Review of clinical data, hematoxylin and eosin (H&E) stained sections and histochemical stains, including those for mucopolysaccharides (Alcian blue and/or collodial iron).

Pathology observed under light microscopy, as well as, post-surgical clinical outcomes.

Nine patients underwent fifteen corneal transplants for corneal clouding (14/15 procedures were deep anterior lamellar keratoplasty). All corneas had mucopolysaccharide deposition visible on H&E stained secti sections and highlighted by special histochemical stains (Alcian blue and collodial iron). These changes, although subtle, should alert the pathologist to the possibility of an underlying lysosomal storage disorder.

The purpose of this study was to summarize key findings from a systematic review of the effectiveness and safety of transepithelial corneal crosslinking (CXL) compared with epithelium-off CXL for progressive keratoconus.

Cochrane systematic review.

We included in our review only randomized controlled trials (RCTs) in which transepithelial and epithelium-off CXL had been compared among participants with progressive keratoconus. The primary outcome was keratoconus stabilization based on post-operative maximum keratometry (Kmax). We adhered to Cochrane methods for trial selection, data extraction, risk of bias evaluation, and data synthesis.

Thirteen RCTs with 567 participants (661 eyes) were included; 11 studies compared non-iontophoresis-assisted transepithelial with epithelium-off CXL. Keratoconus stabilization was described as an outcome in 2 studies. The estimated difference in Kmax means (ie, the "mean difference," MD) from meta-analysis of 177 eyes in 5 RCTs indicated that there were no differences between intervention groups in Kmax at 12 months or later (MD 0.
