Prospective Evaluation of 68Ga-DOTATATE and 18F-DOPA PET Scans in Detecting Tumors Causing Ectopic ACTH Syndrome.

Context: Identification of tumors causing ectopic ACTH syndrome (EAS) is challenging. 68Ga-DOTATATE (DOTA) and 18F-DOPA (DOPA) PET/CT scans are promising imaging modalities warranting further evaluation.

Objective: Compare DOTA and DOPA PET/CT performance in detecting ectopic sources of ACTH.

Evaluation of Secondary Bacterial Infections and Determination of Antibiogram Susceptibility Testing in Hospitalized Patients with COVID-19.

Background & Objective: COVID-19 is a global pandemic that has caused an increase in hospitalization rates and high mortality. Secondary bacterial infections in hospitalized patients are one of the common complications of this viral disease. Due to the increased prevalence of antibiotic resistance, treating these patients is challenging.

Selective laser trabeculoplasty for the treatment of intraocular pressure elevation after viscocanalostomy with Ologen implant in the management of primary open-angle glaucoma: a retrospective cohort study.

Background: Selective laser trabeculoplasty (SLT) is a non-invasive treatment option for glaucoma. It uses a Q-switched Nd: YAG laser. The aim of this study was to evaluate the efficacy of SLT as a treatment option for eyes with primary open-angle glaucoma (POAG) that have previously undergone viscocanalostomy with an Ologen implant, displaying uncontrolled intraocular pressure (IOP).

Role of the amygdala opioid system in the effects of stress on the post-learning sleep patterns of male Wistar rats.

Objectives: Three physiological processes interact: sleep, learning, and stress. It is essential to understand how stress affects and interacts with the link between sleep, learning, and memory since it has long been recognized that sleep plays a crucial role in memory consolidation and learning. Through naloxone injection in the baso lateral amygdala (BLA), this study intends to shed light on the interactions between stress, learning, and sleep, as well as the function of the opioid system and its impact on brain-derived neurotrophic factor (BDNF) production in the hippocampus.
