Integrating ex situ biomimetic extraction analyses into contaminated sediment assessment and management decisions.

This study evaluated a novel ex situ passive sampling biomimetic extraction (BE) method to estimate toxic potency in sediments. Gas chromatography with flame ionization detection (GC-FID) analysis of polydimethylsiloxane fibers equilibrated with field sediments was used to quantify bioavailable polyaromatic hydrocarbons (PAHs) and other unresolved, site-specific contaminant mixtures. This method is biomimetic because contaminants partition to the fiber based on hydrophobicity and abundance, and GC-FID quantification accounts for all constituents absorbed to the fiber that may contribute to toxicity.

Background: Post-operative pancreatic fistula is a common and morbid complication of pancreaticojejunal anastomosis. While gastrointestinal anastomosis is typically performed using absorbable sutures, this issue has prompted experimentation with non-absorbable sutures. This study aims to assess the available literature to provide recommendations on suture choice in this anastomosis.

However, as electromagnetic radiation power increases, the temperature of the absorbing honeycomb increases rapidly, even leading to burning. Therefore, it is significant to possess an efficient and accurate assessment of the thermal effects of absorbing honeycombs under electromagnetic radiation.

This study reports the development of a highly absorbent Chitosan (CS)/Tannic Acid (TA) sponge, synthesized via chemical cross-linking with Epichlorohydrin (ECH) and integrated with zinc oxide nanoparticles (ZnO NPs) as a novel hemostatic anti-infection agent. The chemical properties of the sponges were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and zeta potential measurements. Morphological and elemental analyses conducted through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDAX) revealed a uniform distribution of ZnO NPs, with particle sizes below 20 nm.

Rationale: The biodegradable polymer BioMatrix Alpha™ stent contains biolimus A9 drug which is sirolimus derivative increase in lipophicity. The biodegradable polymer sirolimus eluting Combo™ stent is a dual-therapy sirolimus-eluting and CD34+ antobody coated stent capturing endothelial progenitor cells (EPCs).
Hypothesis: The main hypothesis of the SORT OUT XI trial was that the biodegradable polymer biolimus A9 BioMatrix Alpha ™ stent is noninferior to the biodegradable polymer sirolimus eluting Combo™ stent in an all-comers population with coronary artery disease undergoing percutaneous coronary intervention (PCI).
