Background: Little is known about immediate responses of blood perfusion to the balloon pulmonary angioplasty (BPA) procedure.
Objectives: To investigate the changes in pulmonary perfusion of balloon-dilated vessels and untreated vessels with before, immediately after a single BPA and at follow-up.
Design: Retrospective single-center cohort study.
Article Synopsis
- The study investigates the clinical value of FDG PET/CT imaging in relapsing polychondritis (RP) patients with airway involvement, looking at its ability to predict disease patterns, severity, and prognosis.
- A total of 52 RP patients were analyzed, with the majority showing increased FDG uptake in the airways and three distinct patterns of involvement identified (focal, multifocal, and diffuse).
- Findings indicate that while PET/CT is effective in assessing airway involvement, higher FDG uptake is associated with worse overall patient well-being, although it does not directly correlate with symptom control or pulmonary function.
To understand the propagation characteristics of water trees at a wide temperature range, this paper presents the effect of mechanical behaviors on the sizes of water trees. An accelerated water tree aging experiment was performed at -15 °C, 0 °C, 20 °C, 40 °C, 60 °C, and 80 °C for crosslinked polyethylene (XLPE) specimens, respectively. Depending on the micro observations of water tree slices, water tree length is not always increasing with the increase in temperature.

On the other hand, this natural stochasticity can be valuable for hardware security applications. Here we propose and demonstrate a novel true random number generator utilizing the stochastic delay time of threshold switching in a Ag:SiO diffusive memristor, which exhibits evident advantages in scalability, circuit complexity, and power consumption.

Material And Methods: The implant surfaces comprised a resorbable media CaP microblasted (control) and a CaP resorbable media+silica-boost microblasted (experimental) surfaces. Surfaces were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and optical interferometry (IFM) down to the nanometric level.
Objective: To review the long-term clinical effect of composite transplantation of allogeneic acellular dermal matrix (ADM) and split thickness skin autograft (STSG).
Methods: Nineteen patients with 34 wounds transplanted with allogeneic ADM combined with STSG who were hospitalized from March 2001 to October 2008 were enrolled as composite transplantation group (CT). Another 9 patients with 11 wounds transplanted with STSG admitted within the same time frame were enrolled as control group (C).
