The interaction of a dipole antenna with a human eye model in the presence of a metamaterial is investigated in this paper. The finite difference time domain (FDTD) method with convolutional perfectly matched layer (CPML) formulation have been used. A three-dimensional anatomical model of the human eye with resolution of 1.25 mm × 1.25 mm × 1.25 mm was used in this study. The dipole antenna was driven by modulated Gaussian pulse and the numerical study is performed with dipole operating at 900 MHz. The analysis has been done by varying the size and value of electric permittivity of the metamaterial. By normalizing the peak SAR (1 g and 10 g) to 1 W for all examined cases, we observed how the SAR values are not affected by the different permittivity values with the size of the metamaterial kept fixed.

Purpose: To investigate the effect of Ca2+/calmodulin-dependent protein kinase II (CAMKII) δ subtypes (CAMK2D) on sodium iodate (NaIO3)-induced retinal degeneration in mice.
Methods: Bioinformatics analysis and Western blot experiments were used to screen the significantly differentially expressed genes in age-related macular degeneration (AMD) disease. CAMK2D knockdown and overexpression models were constructed by lentivirus (LV) infection of adult retinal pigment epithelial cell line-19 (ARPE-19) cells in vitro.

Introduction: Health-related quality of life (HR-QoL) outcomes following maxillary reconstruction with the scapular osseous free flap (SOFF) are lacking. Material and Methods: To determine these outcomes, a study of patients who completed maxillary reconstruction with flap survival of the SOFF between 2016 and 2023 was conducted, using Face-Q Head and Neck Cancer Module (FACE-Q).
Results: Eligible patients had at least six months of follow-up.

Aim: The objective of the present study is to assess and compare the effectiveness of two different anesthetic agents, namely, 4% articaine and 2% lignocaine, in the extraction of primary molar teeth in children.
Materials And Methods: The study included 25 children requiring bilateral extractions of primary molar, with extraction performed on one side with 4% articaine and the contralateral side extraction with 2% lignocaine at two separate appointments. The anesthetic efficacy was evaluated objectively by assessing pain and the child's behavior at baseline, during injection and during extraction using the sound, eye, and motor (SEM) scale objectively, and subjectively using the faces pain rating scale (FPS).
