Wearable Iron Lung Helps COPD Patients Breathe Easier

Chronic obstructive pulmonary disease (COPD) has few treatment options, with patients frequently experiencing shortness of breath. To address this most unwelcome symptom of COPD, Dr. Jake Brenner, a critical care physician specializing in pulmonology...

Abstract An iron-nickel bimetallic metal-organic framework (FeNi-MOF) with inner peroxidase-like activity as a support for enzyme immobilization was synthesized for the first time. And the GOx-mediated synthesis of mimic multienzyme system (GOx/FeNi-MOF) was obtained by a one-step biomimetic mineralization. FeNi-MOF played a dual role of a peroxidase mimic and a protective coating. Therefore, the obtained multienzyme system showed both peroxidase-like activity of FeNi-MOF and the biological activity of natural enzyme. FeNi-MOF acted as a peroxidase mimic, showing a higher affinity for hydrogen peroxide (H2O2). The...

Ferroptosis is characterized by iron-dependence and lipid hydroperoxides accumulation, and its primary mechanism involves the suppression of system Xc−-GSH (glutathione)-GPX4 (glutathione peroxidase 4) axis. Co-incidentally, cancer cells are also metab...

EckertAbstractFe–Cr–Mo–B–C amorphous powders are usually used in thermal spraying, spark plasma sintering or 3D printing to prepare coatings or large-sized bulk amorphous alloys. However, their non-isothermal crystallization kinetics is far from being investigated in detail because of their relatively complicated crystallization behavior. In this work, the phase evolution, crystallization kinetics and crystallization mechanism of Fe&n...

In this work, g-C3N4 was employed as a support for distributing, stabilizing nZVI and further changing the composition, microstructure and electronic structure of nZVI due to the interactions between the iron nanoparticles and g-C3N4 sheet. Adjusting the micro-structure of nZVI to enhance the adsorption ability, control the electron...

We comprehensively evaluated and compared the effects of direct dosing of waterworks Fe-/Al-sludge in pilot-scale sewer rising mains, particularly focusing on removal of sulfides and phosphate and underlying p...

The reaction of ABTS with equimolar amounts of Fe(VI) stopped at the formation of ABTSâ—Ź+, accompanied by the complete reduction of Fe(VI) to produce F...

Conclusions: Although all iron treatments analyzed are effective and safe, our results suggest that iron protein succinylate may be an excellent choice to treat iron deficiency and anemia due to its superior effectiveness and tolerability. PMID: 31944128 [PubMed - as supplied by publisher]

We examined associations between mortality and accelerometer-measured PA using age-relevant intensity cutpoints in older women of various ethnicities. The results support the hypothesis that higher levels of accelerometer-measured PA, even when below the moderate-intensity threshold recommended in current guidelines, are associated with lower all-cause and CVD mortality in women aged 63 to 99. Our findings expand on previous studies showing that higher self-reported PA reduces mortality in adults aged 60 and older, specifically in older women, and at less than recommended amounts. Moreover, our findings challenge th...
