In today's digital age, there is an increasing demand for integrated wireless and wired technologies; however, there is a difficulty in achieving secure and reliable communications within buildings and facilities. This paper presents a proposal for maintaining the infrastructure while expanding it to implement communication technologies with high transmission and reception speeds and high levels of data confidentiality to enhance the operational efficiency of organizations. Three main technologies have emerged as promising solutions for this purpose: Wi-Fi, Li-Fi, and BPL.

Methodology This is a retrospective study of patients presenting to the National Cancer Institute, Cairo University, Egypt from January 2005 to December 2019 with pathologically proven locally advanced rectal cancer who had a complete clinical response after neoadjuvant treatment. Patients who underwent surgery after achieving complete clinical response and patients who were kept under watchful waiting were compared in terms of overall survival (OS), disease-free survival (DFS), metastasis-free survival (MFS), and local recurrence-free survival (LRFS).

Drug resistance is linked to overexpression of matrix metalloproteinases (MMPs) and aberrant calcium signalling.

This approach leverages quenching of the Tb-ACAC luminescence upon binding to CA-125. Characterization of the photoprobe film through UV-vis and fluorescence measurements confirmed the presence of Tb-ACAC within the polymer matrix.
