Herein, the novel double Z-scheme Ag-AgO/CuO-CuFeO magnetic nanophotocatalyst with nanosphere-on-nanosheet-like morphology was synthesized via the corona-plasma-assisted starch-templated microwave-combustion-precipitation method to remove the dye pollutants. The CuO-CuFeO meso/macroporous nanophotocatalyst was synthesized using a one-pot-stage combustion-microwave process with/without starch as a hard-template. Subsequently, surface modification was carried out by DC corona-plasma discharge technology at various voltages, namely 500, 1000 and 1500 V.

We investigated the effects of intravenous (IV) ketamine on intraoperative bleeding and the need for oxytocin in CS under spinal anesthesia (SA).
Methods: This study, took place at Alzahra hospital during 2020.
Background: Compared to the general population, persons with multiple sclerosis (MS) are at increased risk of suffering from major depressive disorder (MDD). Repetitive Transcranial Magnetic Stimulation (rTMS) was used successfully to treat individuals with MDD. Here, we conducted a randomized clinical trial and pilot study, and tested the effectiveness of rTMS adjuvant to a standard pharmacological treatment among persons with MS, compared to a sham condition.

Therefore, this study was done to determine the effect of family presence on weaning success in patients admitted to intensive care units (ICUs).
Materials And Methods: The present interventional quasi-experimental study was performed on 154 patients undergoing mechanical ventilation who were selected through available sampling method and based on inclusion criteria and were randomly divided into intervention and control groups.
In Wireless Body Area Networks (BAN), energy consumption, energy harvesting, and data communication are the three most important issues. In this paper, we develop an optimal allocation algorithm (OAA) for sensor devices, which are carried by or implanted in human body, harvest energy from their surroundings, and are powered by batteries. Based on the optimal allocation algorithm that uses a two-timescale Lyapunov optimization approach, we design a framework for joint optimization of network service cost and network utility to study energy, communication, and allocation management at the network edge.

Objectives: This study aimed to evaluate the quality of glycemic management during CABG in an academic center regarding peripheral blood and coronary sinus values.
Methods: This prospective descriptive study encompassed 55 eligible patients undergoing on-pump CABG surgery in 2020.
Patients with confirmed SARS-CoV-2 are principally at risk of emerging superinfections, particularly those caused by Gram-negative bacteria. Therefore, in this retrospective cohort study, we investigated the presence of bacteria in endotracheal aspirate samples in severe COVID-19 patients under mechanical ventilation between 20 February 2020 and 21 September 2020 in Mazandaran Heart Center Hospital, Iran. Outcomes were compared between ICU patients with confirmed SARS-CoV-2 (corona group) and those who suffer from other disease (non-corona group).
