Spattering mechanism of laser powder bed fusion additive manufacturing on heterogeneous surfaces.

Laser powder additive manufacturing (PBF-LB) is an additive manufacturing method capable of producing high-precision and fully dense parts. However, nondestructively quality assurance of no internal defects remains challenging. Mitigating internal defects requires elucidating their formation mechanism and improving the PBF-LB process conditions.

Risks of Muscle Atrophy in Patients with Malignant Lymphoma after Autologous Stem Cell Transplantation.

Objective: Muscle atrophy is associated with autologous stem cell transplantation (ASCT)-related outcomes in patients with malignant lymphoma (ML). However, the impact of ASCT on muscle mass remains unclear in patients with ML. The aims of this study were to investigate changes in muscle mass and risk profiles for muscle atrophy after ASCT.

Postcatheterization radial arteriovenous fistula: balloon-assisted direct percutaneous embolization with N-butyl cyanoacrylate and 50 % glucose solution in two sessions.

We report an iatrogenic radial arteriovenous fistula (AVF) in a 74-year-old woman presenting with right radial bruit and pain 8 months after sheath removal for cardiac catheterization. She refused surgical ligation and underwent balloon-assisted direct percutaneous embolization of the draining vein with N-butyl cyanoacrylate (NBCA). Another draining vein that developed immediately after the procedure was conservatively treated with 1 month of continuous band compression.
