Traumatic intraocular foreign bodies: correlation between size and structural damage

Journal of the Egyptian Ophthalmological Society, 2023
Background Ophthalmic trauma caused by intraocular foreign bodies (IOFBs) can impact visual prognosis by generating direct ocular structural damage. Factors bearing poor visual prognosis are related to size and velocity of IOFB, location in posterior ...

Shape Memory Polymer‐Based Flexible Pressure Sensor for Real‐Time Venous Thrombosis Monitoring

Advanced Materials Interfaces, EarlyView.
A shape‐memory tubular flexible pressure sensor with a 100‐mesh microstructured SMP‐PLA/MWCNTs sensing layer was developed for PICC‐mounted monitoring of thrombosis‐related pressure changes. The sensor combines high sensitivity (204 kPa−1), a fast response time (28 ms), and conformal catheter fixation and was validated by hydrostatic and ex vivo ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
