While benzodiazepines have been a mainstay of the pharmacotherapy of anxiety disorders, their short-term efficacy and risk of abuse have driven the exploration of alternative treatment approaches. The endocannabinoid (eCB) system has emerged as a key modulator of anxiety-related processes, with evidence suggesting dynamic interactions between the eCB system and the GABAergic system, the primary target of benzodiazepines. According to the existing literature, the activation of the cannabinoid receptors has been shown to exert anxiolytic effects, while their blockade or genetic deletion results in heightened anxiety-like responses.

Background: Concerning maternity service, the mother's quality assessment is central because emotional, cultural, and respectful support is vital during labour and the delivery process. Studies concerning the perceived quality of maternity services from the perspective of mothers have rarely been carried out in Iranian hospital settings. Therefore, this study aimed to measure the gap between the expectations of patients with maternity services and their perceptions of the service and identify associated factors at a maternity hospital in northwest Iran using service quality (SERVQUAL) and health quality (HEALTHQUAL) questionnaires.

Background: Excessive prescription of antibiotics in infants increases the risk of short-term and lifelong morbidity and mortality. Nonetheless, the use of antibiotics in neonatal intensive care units (NICUs) is significantly high. This is primarily because neonatologists are concerned about the fragile immune systems of newborns, their vulnerability to serious infectious diseases, and the challenge of accurately distinguishing between infectious and non-infectious conditions.

With the increasing global attention to deep learning and the advancements made in applying convolutional neural networks in electromagnetics, we have recently witnessed the utilization of deep learning-based networks for predicting the spectrum and electromagnetic properties of structures instead of traditional tools like fully numerical-based methods. In this study, a Convolutional Neural Network (CNN is proposed for predicting spoof surface plasmon polaritons, enabling the examination of the absorption spectrum of metallic multilevel-grating structures (MMGS) and designing various sensor devices and absorbers in the shortest time possible. To expedite the training process of this network, a semi-analytical method of rigorous coupled-wave analysis (RCWA) enhanced with the fast Fourier factorization (FFF) technique has been employed, significantly reducing the data generation time for training.
