Article Synopsis
- Drug-coated balloon (DCB) catheters are a new option for treating coronary issues, delivering drugs directly to blood vessel walls without the need for permanent stents.
- Recent evidence supports their use not only in recurrent restenosis but also in treating new coronary diseases and chronic total occlusions (CTO).
- A case study showed successful use of a DCB-only strategy in a 49-year-old male with multivessel occlusions, highlighting the need for more research on the long-term effectiveness of DCBs in these scenarios.
Biodegradable polymers are desirable to mitigate the environmental impact of plastic waste in the environment. Over the past several decades, the development of organocatalytic ring-opening polymerization (OROP) has made the synthesis of many new types of biodegradable polymers possible. In this research article, the first example of an oxygen atom transfer reagent pendant on a biodegradable polymer backbone is reported.

Specific lysis of the target cells can be determined by labeling the target cells with a radioactive isotope or fluorescent molecule, co-incubating it with an effector cell, then measuring the release of the labeled molecule in the supernatant. Here, we describe and compare different cell cytotoxicity assays using a chromium-51 (Cr) release and DELFIA EuTDA fluorescent assay using K562 as the target cells and peripheral blood mononuclear cell (PBMC) derived natural killer (NK) cells as the effector cells.

Local, intralesional delivery of collagenase (MZ-004) may facilitate guidewire crossing in CTO.
Aims: To evaluate the effect of MZ-004 in facilitating antegrade wire crossing in CTO angioplasty.
Background: Description of procedural outcomes using contemporary techniques that apply specialized coronary guidewires, microcatheters, and guide catheter extensions designed for chronic total occlusion (CTO) percutaneous revascularization is limited.
Methods: A prospective, multicenter, single-arm study was conducted to evaluate procedural and in-hospital outcomes among 150 patients undergoing attempted CTO revascularization utilizing specialized guidewires, microcatheters and guide extensions. The primary endpoint was defined as successful guidewire recanalization and absence of in-hospital cardiac death, myocardial infarction (MI), or repeat target lesion revascularization (major adverse cardiac events, MACE).
