Classical Ozaki Procedure in a Seven-Month-Old Infant.

We present a case study of neotricuspidization of the aortic valve with neocusp suturing based on templates similar to those used in the Ozaki procedure but adapted for infants. This is an alternative for patients when valve reconstruction is impossible or risky. A good postoperative hemodynamic outcome was obtained, but it is necessary to evaluate this approach on the basis of long-term results.

PLA-PEG Implant as a Drug Delivery System in Glaucoma Surgery: Experimental Study.

Unlabelled: Excessive postoperative scarring halts the effectiveness of glaucoma surgery and still remains a challenging problem. The purpose of this study was to develop a PLA-PEG-based drug delivery system with cyclosporine A or everolimus for wound healing modulation.

Methods: PLA-PEG implants saturation with cyclosporine A or everolimus as well as their further in vitro release were analyzed.

Vector spherical harmonic analysis and experimental validation of spherical shells illuminated with broadband, millimeter wave Gaussian beams: applications to corneal sensing.

Coupling to longitudinal modes of thin spherical shells, under Gaussian-beam illumination, was explored with a theoretical method based on Fourier-optics analysis and vector spherical harmonics and was scrutinized with an experimental setup. For the theory part, the illumination frequency band was fixed between 100-600 GHz and the outer spherical shell radius of curvature and thickness are 7.5 mm and 0.

Calibration Alignment Sensitivity in Corneal Terahertz Imaging.

Improving the longitudinal modes coupling in layered spherical structure contributes significantly to corneal terahertz sensing, which plays a crucial role in the early diagnosis of cornea dystrophies. Using a steel sphere to calibrate reflection from the cornea sample assists in enhancing the resolution of longitudinal modes. The requirement and challenges toward applying the calibration sphere are introduced and addressed.

Characterization of Silver Nanowire Layers in the Terahertz Frequency Range.

Thin layers of silver nanowires are commonly studied for transparent electronics. However, reports of their terahertz (THz) properties are scarce. Here, we present the electrical and optical properties of thin silver nanowire layers with increasing densities at THz frequencies.
