Aim: We aimed to investigate the effects of a single carbon dioxide (CO) treatment on arterial stiffness by monitoring the changes of aortic pulse-wave velocity (PWV) and aortic augmentation index (AIXao), which are indicators of arterial stiffness.
Patients And Methods: PWV and AIXao were measured by an invasively validated oscillometric device. The measurements of stiffness parameters were performed before the CO treatment, and at 1, 4 and 8 h after the first treatment.
Results: Thirty-one patients were included. No significant changes were found in PWV. AIXao decreased significantly 1 h and 4 h after CO treatment compared to baseline values (p=0.034 and p<0.001). AIXao increased 8 h after the CO treatment, but remained significantly lower than baseline AIXao values (p=0.016).
Conclusion: CO treatment is capable of reducing peripheral vascular resistance. We hypothesize that CO is not only a temporal vasodilator but is also capable of activating vasodilation pathways.

One-step adsorptive purification of ethylene (C2H4) from ternary mixture comprising of acetylene (C2H2), ethylene (C2H4) and carbon dioxide (CO2) is a great challenge in the chemical industry. Herein, a microporous metal-organic framework (FJI-H38) has been reported, which possesses a high density of electronegative O/N binding sites and appropriate pore size. Notably, at 0.

Carbon dioxide capture underpins an important range of technologies that can help to mitigate climate change. Improved carbon capture technologies that are driven by electrochemistry are under active development, and it was recently found that supercapacitor energy storage devices can reversibly capture and release carbon dioxide. So-called supercapacitive swing adsorption (SSA) has several advantages over traditional carbon dioxide capture technologies such as lower energy consumption and the use of nontoxic materials.

Quantifying how co-acting global change factors (GCFs) influence plant invasion is crucial for predicting future invasion dynamics. We did a meta-analysis to assess pairwise effects of five GCFs (elevated CO, drought, eutrophication, increased rainfall and warming) on native and alien plants. We found that alien plants, compared to native plants, suffered less or benefited more for four of the eight pairwise GCF combinations, and that all GCFs acted additively.

The increased use of dairy fat in various applications is facilitated by its fractionation into hard and liquid fractions. Herein, the fractionation of bovine ghee and buffalo ghee was investigated, and triacylglycerol (TAG) profiles of milk fat fractions and 2 categories of infant formulas fat were quantified by using ultra-performance convergence chromatography quadrupole time-of-flight mass spectrometry (UPC-Q-TOF-MS) using carbon dioxide as the mobile phase. Furthermore, the thermal behavior of the different samples was evaluated, and tocopherols content was also quantified.

The maritime transport sector poses significant air quality concerns, particularly in nearby cities. Ultrafine particles (UFP, diameter < 100 nm) are of particular concern due to their potential health impacts. This study measured particle number concentrations (PNC), size distributions (PNSD), and other pollutants including particulate matter (PM), nitrogen oxides (NO), black carbon (BC), sulfur dioxide (SO) and ozone (O), organic markers and trace elements at a major European harbor and an urban background (UB) location.
