Inhaled Aviptadil is a New Hope for Recovery of Lung Damage due to COVID-19.

Objective: We are still in search of new therapeutic options for COVID-19 to prevent new infections, enable fast recovery and reduce the long-lasting symptoms or sequelae. This study aimed to investigate the short- and long-term effects of inhaled aviptadil on hospitalized, adult COVID-19 patients.

Methods: A multicenter, prospective, placebo-controlled, comparative, randomized, double-blind clinical trial was conducted.

Relationship between oxidative stress and endometrial polyps in pre-and postmenopausal women.

Objective: This study aimed to investigate the relationship between oxidative stress (OS) and endometrial polyps (EP) in pre- versus postmenopausal women with abnormal uterine bleeding.

Methods: This prospective case control study was conducted in the Gynecology Department of Ankara Bilkent City Hospital between January and December 2019. In this study, the EP and control groups included 45 participants each (30 pre- and 15 postmenopausal women).

Elevated estradıol ın a prepubertal female: wıthın-laboratory systematıc and practıcal ınterference screenıng.

Analytical errors related to endogenous or exogenous substances are a cause of unnecessary investigation, intervention, and patient concern especially in immunoassay platforms. In this report, we systematically screened for estradiol interference using a practical algorithm. For extended research in interference screening, repeated estradiol measurements for control and case samples were carried out for method comparison (three immunoassay platforms and one liquid chromatography-mass spectrometry (LC-MS/MS) measurement), dilution test, polyethylene glycol (PEG) precipitation, and heterophile antibody blocking tube.

Experiences of Intern Nurses Returning From Distance Education to Clinical Practice During the COVID-19 Pandemic: A Qualitative Study.

Rationale: The present study aimed to understand the experiences of intern nurses returning to clinical practice after a year-long distance education during the pandemic.

Methods: The study was conducted using the qualitative content analysis method. The participants were 32 intern nurses.

Application of Redox-Responsive Cysteine-Based Organogels as a Drug Delivery System for Doxorubicin.

Cysteine derivatives having disulfide bonds in their side chains can be used as redox-responsive organogelators. The disulfide bond can be cleaved in the presence of certain reducing agents like thiol derivatives such as glutathione (GSH), which is a tripeptide that consists of cysteine, glutamic acid, and glycine. Studies show that cells of certain cancers have higher levels of glutathione due to increased production of reactive oxygen species (ROS).
