DOI: 10.1002/pc.24629
Abstract: A novel intumescent flame retardant poly(butylene succinate) (IFR-PBS) with antidripping property was prepared using halloysite nanotubes (HNTs) as the synergistic agent. Ammonium polyphosphate (APP), melamine (MA), pentaerythritol (PER), and halloysite nanotubes (HNTs) were added in… read more here.

DOI: 10.1007/s00380-020-01562-8
Abstract: We hypothesized that in patients with QT prolongation, resistance might not decrease in the wave-free period, because QTU prolongation cannot be detected by instantaneous wave-free ratio (iFR) analysis software. We investigated whether corrected QTU (QTUc)… read more here.

DOI: 10.1007/s10973-017-6425-y
Abstract: Polylactide (PLA) composites based on intumescent flame-retardant (IFR) and organo-modified sepiolite (OSEP) were prepared via direct melt compounding. The uniform dispersion of OSEP in the PLA matrix was observed by TEM, but some agglomerates still… read more here.

Hyperemic versus non-hyperemic indexes for coronary physiology assessment in patients with severe aortic stenosis.
Sign Up to like & getrecommendations! Published in 2021 at "Advances in medical sciences"
DOI: 10.1016/j.advms.2021.07.008
Abstract: PURPOSE Recent data suggests that fractional flow reserve (FFR) may underestimate intermediate coronary stenosis in the presence of severe aortic stenosis (AS), whereas instantaneous wave-free ratio (iFR) values may remain similar after treatment of AS,… read more here.

DOI: 10.1016/j.ahj.2021.05.004
Abstract: BACKGROUND Angiography-derived physiological assessment of coronary lesions has emerged as an alternative to wire-based assessment aiming at less-invasiveness and shorter procedural time as well as cost effectiveness in physiology-guided decision making. However, current available image-derived… read more here.
