Origins and conservation of topological polarization defects in resonant photonic-crystal diffraction.

We present a continuative definition of topological charge to depict the polarization defects on any resonant diffraction orders in photonic crystal slab regardless they are radiative or evanescent. By using such a generalized definition, we investigate the origins and conservation of polarization defects across the whole Brillouin zone. We found that the mode crossings due to Brillouin zone folding contribute to the emergence of polarization defects in the entire Brillouin zone.

Adrenaline Dilution in Dental Local Anesthetic Cartridges: A Practical Method Using the Inner Needle of Intravenous Catheter.

Local anesthesia is a routine medical procedure for dentists. To achieve the desired anesthetic effect of lidocaine and favorable hemostatic effects by adrenaline, the combination of 2% lidocaine + 1:80,000 adrenaline is commonly used, including in dental patients with underlying diseases for whom adrenaline in local anesthetics is problematic due to its vasoconstrictive effects, as the adrenaline concentration in dental local anesthetic cartridges in Japan is commercially set at 1:80,000. To reduce the effect of adrenaline on the cardiovascular system, adrenaline is sometimes diluted in dental local anesthetic cartridges.

Mid-term Clinical and Radiographic Outcomes of the Actis Total Hip System: A Retrospective Study.

Introduction Implant technology for total hip arthroplasty (THA) was developed to improve hip function and patient satisfaction. Actis (DePuy Synthes, Warsaw, IN, USA) is a short fit-and-fill titanium stem, with a medial-collared and triple-taper (MCTT) geometry, that is fully coated with hydroxyapatite (HA). We evaluated the radiographic and clinical outcomes of the Actis Total Hip System during a mean follow-up of five years.

[CLINICAL EVALUATION OF THERAPEUTIC EFFECT PREDICTORS IN PEMBROLIZUMAB FOR ADVANCED UROTHELIAL CANCER].

(Purpose) We performed a clinical retrospective study on the evaluation of pembrolizumab treatment results for advanced urothelial cancer in our hospital. (Materials and Methods) Twenty-seven patients diagnosed with advanced or metastatic urothelial carcinoma who received pembrolizumab between April 2018 and December 2021 were included. We retrospectively reviewed medical records to examine treatment outcomes, immune-related adverse event (irAE), and prognostic factors.

Xenographic lenticule implantation followed by riboflavin and UV treatment: A promising alternative for corneal ectasias management.

The cornea is the primary refracting surface of the eye, requiring precise curvature to ensure optimal vision. Any distortion in its shape may result in significant visual impairment. Corneal ectasias, such as keratoconus (KC), is characterized by gradual thinning and protrusion of the thinned area, due to biomechanical weakening of the tissue, leading to astigmatism and vision loss.
