Effect of site-specific conditions and operating parameters on the removal efficiency of petroleum-originating pollutants by using ozonation.

Soil contamination is a worldwide problem, mainly caused by a wide range of organic compounds: e.g., alkanes, aromatics, and polynuclear aromatics.

Mycoremediation effect of Trichoderma harzianum strain T22 combined with ozonation in diesel-contaminated sand.

This study aimed to determine the ability of the fungus Trichoderma harzianum strain T22 (Th-T22) to utilize diesel fuel as a carbon source. The potential use of Th-T22 for diesel bioremediation in an artificial soil was tested by inoculating a diesel-sand mixture with a fungal mycelial suspension of Th-T22. Given the ability of ozone to degrade compounds with low biochemical reactivity, the effect of a pre- and post-ozonation was also evaluated.

Case of a patient with heart failure, dilated cardiomyopathy and atrial fibrillation treated with sacubitril/valsartan.

A novel combination consisting of the neprilysin inhibitor, sacubitril, and the angiotensin-receptor blocker, valsartan (belonging to the newly established class of angiotensin receptor/neprilysin inhibitors), was shown to be effective in the treatment of heart failure (HF) by improving patient clinical status, and reducing re-hospitalization rate and mortality. We report a case of a 29 year old male with HF, dilated cardiomyopathy possibly related to myocarditis and atrial fibrillation with reduced ejection fraction. Sacubitril/valsartan treatment was initiated after two years of standard treatment.

Probing Mitochondrial Permeability Transition Pore Activity in Nucleated Cells and Platelets by High-Throughput Screening Assays Suggests Involvement of Protein Phosphatase 2B in Mitochondrial Dynamics.

Mitochondrial permeability transition pore (mPTP) formation is well documented in isolated mitochondria. However, convincing detection of mPTP in whole cells remains elusive. In this study, we describe a high-throughput assay for Ca-activated mPTP opening in platelets using HyperCyt flow cytometry.

CO and NO from water resource recovery facilities: Evaluation of emissions from biological treatment, settling, disinfection, and receiving water body.

Water resource recovery facilities (WRRFs) contribute to climate change and air pollution, as they are anthropogenic potential sources of direct and indirect emission of greenhouse gases (GHGs). Studies concerning the monitoring and accounting for GHG emissions from WRRFs are of increasing interest. In this study, the floating hood technique for gas collection was coupled with the off-gas method to monitor and apportion nitrous oxide (NO) and carbon dioxide (CO) emissions from both aerated and non-aerated tanks in a municipal water resource recovery facility, in order to investigate its carbon footprint (CFP).
