Precise description of the interaction between molecular oxygen and metal surfaces is one of the most challenging topics in quantum chemistry. In this work, we use low-temperature scanning tunneling microscopy (STM) to identify and characterize an adsorption state of molecular oxygen that coordinates to three Ag atoms (μ) on Ag(100). Surprisingly, μ-O cannot be identified as a stable configuration with generalized gradient approximation (GGA)-level density functional theory (DFT) calculations.

This study presents a hybrid layered composite nanofiber mesh (LHN) designed for localized treatment in GB tumor bed. The LHN, consisting of polyvinyl alcohol and core-shell polylactic acid layers, was loaded with TMZ and rutin.

However, long-term systemic transcriptomic changes associated with COVID-19 disease and the impact of disease severity are not fully understood. We aimed to investigate the impact of COVID-19 and its severity on transcriptomic alterations in peripheral blood mononuclear cells (PBMCs) following 1 year of the disease.

- Post-COVID interstitial lung disease (ILD) is a condition affecting COVID-19 survivors, characterized by persistent respiratory symptoms and lung function abnormalities, often identified through CT scans.
- A study analyzed data from 375 patients who experienced lingering symptoms three months after recovering from COVID-19, finding that 262 of them (about 70%) had post-COVID ILD, with common symptoms including shortness of breath, exercise intolerance, fatigue, and cough.
- Risk factors for developing post-COVID ILD included active smoking and having been admitted to intensive care during the acute phase of the disease; typical CT findings included ground glass opacities and fibrotic changes, indicating lung damage.
Introduction: Patients with airway diseases who bear the burden of smoking need access to smoking cessation support. We aimed to investigate the impact of immediately scheduled appointments on access to smoking cessation clinics compared with usual care in this patient group.
Methods: This multicenter, prospective, randomized, open-label study was conducted between November 2022 and June 2023 at pulmonary outpatient clinics.
