Background: Transcatheter occlusion of the persisting arterial duct (PDA) is feasible using different techniques like coil-embolization (CE), Rashkind PDA occluder (Rash), Amplatzer Duct Occluder (ADO). Comparative studies with this devices in relation to the size of the PDA and the device are missing. Aim of this study was to evaluate the different systems at the own patient population.
Patients And Methods: From 1993 to 12/2001 transcatheter occlusion was attempted in 92 patients aged 4,13 years (range 0,07 to 14,39 years) using CE, Rash or ADO. All patients received echocardiographic examinations 24 hours before and after intervention, after 3, 6, and 12 months and than yearly.
Results: 91/92 PDAs could be successfully closed by 97 interventions. There were 63 CE, 25 Rash and 9 ADO performed. Primary closure rate was 75 % for Rash, 80 % for ADO and 80,8 % for CE (n. s.) and after 6 months 88 % for Rash, 92,3 % for CE and 100 % for ADO (p < 0,001), although the size of the PDA increased significantly from CE (2,14 + 1,1 min) to Rash (3,2 +/- 1,3 min) to ADO (4,9 +/- 1,9 min) (p < 0.05). In 6/7 pts with residual shunts complete occlusion could be achieved by second intervention.
Conclusion: In dependency of the size of the PDA and the right choice of the occluder almost all PDAs are closable with transcatheter techniques.

The study focused on converting tea bag waste into strong fluorescence carbon quantum dots (TBW-CQDs) for the detection of acrylamide in drinking water, antimicrobial activity, and photocatalytic degradation. The TBW-CQDs exhibited blue luminescence and maximum absorbance at 287 nm under UV light and distinctive fluorescence emission and excitation wavelengths at 425 nm and 287 nm, respectively. TBW-CQDs revealed a particle size of 8.

A multifunctional nanoplatform integrating multiple therapeutic functions may be an effective strategy to realize satisfactory therapeutic efficacy in the treatment of tumors. However, there is still a certain challenge in integrating multiple therapeutic agents into a single formulation using a simple method due to variations in their properties. In this work, multifunctional CuS-ICG@PDA-FA nanoparticles (CIPF NPs) with excellent ability to produce reactive oxygen species and photothermal conversion performance are fabricated by a simple and gentle method.

Development of efficient drug delivery systems remains a critical challenge in pharmaceutical applications, necessitating novel approaches to improve drug loading and release profiles. In this study, a novel method is presented for fabricating crosslinked polydopamine particles (XPDPs) using a water/water Pickering emulsion system. The emulsion is composed of poly(ethylene glycol) and dextran, stabilized by polydopamine (PDA) particles.
