Article Synopsis
- Bio-separation is key in biotechnology for isolating biological macromolecules, traditionally using bead-based and expanded bed chromatography.
- A new method, printed monolith adsorption (PMA), utilizes 3D-printed structures to facilitate direct purification from crude samples and can target specific molecules, similar to existing technologies.
- This study combined PMA with an immobilized metal ligand to selectively bind polyhistidine-tagged proteins, achieving effective purification in less time compared to commercial methods while maintaining similar binding capacities.
Adsorptive separation of Pb(II) from aqueous solution containing Pb(II) and other heavy metals (Cu(II), Zn(II) and Cd(II)) has been investigated, using three adsorbents, such as an iminodiacetic acid-chelating resin (CR11) and Fe-based adsorbents (goethite and magnetite). Batchwise adsorption of Pb(II) and other metal ions in single metal system and multi-components system was carried out with varying parameters, such as pH, time and initial concentrations of metals. CR11 possesses the highest adsorption ability for these metals, while the selectivity of individual metal is little.

- The study investigates whether the severity of coronary artery disease (CAD) affects outcomes after transcatheter aortic valve replacement (TAVR), focusing on two specific scores: baseline SYNTAX score (bSS) and residual SYNTAX score (rSS).
- It finds that a higher bSS (> 22) is linked to an increased risk of major adverse cardiac events (MACE), and both bSS and rSS can predict late major/life-threatening bleeding complications (MLBCs).
- Overall, while CAD severity influences the likelihood of bleeding complications, it does not significantly affect overall or cardiovascular mortality in TAVR patients.
The complication of myocardial infarction after using intravenous recombinant tissue plasminogen activator (rt-PA) in patients with acute ischemic stroke is rare. Several of these cases have been reported in the first 3 hours after infusion of rt-PA. There is controversy on how to manage treatment of the coronary artery, such as intravenous anticoagulants and antiplatelets, at the same time.

The residual SYNTAX Score (rSS) aims to assess residual CAD after PCI. The association between kidney function and rSS has not been investigated in ACS patients.
View Article and Find Full Text PDFBackground: Periprocedural and late (>30 days) bleedings represent major complications after transcatheter aortic valve replacement and have been identified as potential areas for improved patient care.
Objectives: The authors sought to evaluate the impact of ongoing primary hemostasis disorders on late major/life-threatening bleeding complications (MLBCs).
Methods: Bleedings were assessed according to the VARC-2 (Valve Academic Research Consortium-2) criteria.
