The (re)emergence of aerosol delivery: Treatment of pulmonary diseases and its clinical challenges.

J Control Release

January 2025

Univ Brest, Inserm, EFS, UMR 1078, GGB, F-29200, Brest, France; CHU de Brest, Service de Génétique Médicale et de Biologie de la Reproduction, F-29200 Brest, France. Electronic address:

Aerosol delivery represents a rapid and non-invasive way to directly reach the lungs while escaping the hepatic first-pass effect. The development of pulmonary drugs for respiratory diseases such as cystic fibrosis, lung infections, pulmonary fibrosis or lung cancer requires an enhanced understanding of the relationships between the natural physiology of the respiratory system and the pathophysiology of these conditions. This knowledge is crucial to better predict and thereby control drug deposition.

Tanz Centre for Research in Neurodegenerative Diseases, University of Toronto, Toronto, Ontario, Canada; Department of Biochemistry, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Bank voles are susceptible to prion strains from many different species, yet the molecular mechanisms underlying the ability of bank vole prion protein (BVPrP) to function as a universal prion acceptor remain unclear. Potential differences in molecular environments and protein interaction networks on the cell surface of brain cells may contribute to BVPrP's unusual behavior. To test this hypothesis, we generated knock-in mice that express physiological levels of BVPrP (M109 isoform) and employed mass spectrometry to compare the interactomes of mouse (Mo) PrP and BVPrP following mild in vivo crosslinking of brain tissue.

Department of Cardiology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland. Electronic address:

Transcatheter edge-to-edge repair (TEER) is an effective intervention for high-risk patients with severe symptomatic mitral regurgitation (MR), but its acute impact on left ventricular (LV) function has not been well studied using advanced echocardiographic techniques. This study investigated the immediate effects of TEER on LV volumes and functions, as well as their influence on mid-term outcomes, using high-resolution 3D transesophageal echocardiography. In 80 patients undergoing TEER for severe MR (mean age 79±8 years, 49% with primary MR), LV end-diastolic volume (LVEDV) and stroke volume significantly decreased (161±61 to 147±54 ml and 69±18 to 50±15 ml, respectively), while end-systolic volume increased (92±60 to 97±45 ml; p<0.

The smile is a complex human facial expression, most commonly associated with joy. We present a detailed view on Leonardo Da Vinci's painting of Saint John the Baptist, between 1516 to 1516, which illustrates a smiling saint, which has evoked multiple explanations and theories. Discussing Da Vinci's concept of painting as science media and the two merely contradictory painting techniques chiaroscuro and sfumato, we attempt to approach this picture.

Objective: Recently, results on colorectal cancer (CRC) incidence and mortality reduction by the offer of screening colonoscopy were reported for the first time from a randomized controlled trial (RCT), the Nordic-European Initiative on Colorectal Cancer (NordICC) trial. Despite randomization, there was a substantially lower proportion of post-randomization exclusions of CRC cases due to cancer registry-recorded date of diagnosis before recruitment in the invited group than in the usual-care group. We aimed to evaluate the impact of such differential exclusions on the trial's effect estimates on CRC risk.

Compartment model of strategy-dependent time delays in replicator dynamics.

J Theor Biol

January 2025

Center for Computational and Theoretical Biology, University of Wuerzburg, Klara-Oppenheimer-Weg 32, Wuerzburg, 97074, Germany; Department of Theoretical Biology, Max Planck Institute for Evolutionary Biology, August-Thienemann-Str. 2, Ploen, 24306, Germany.

Real-world processes often exhibit temporal separation between actions and reactions - a characteristic frequently ignored in many modelling frameworks. Adding temporal aspects, like time delays, introduces a higher complexity of problems and leads to models that are challenging to analyse and computationally expensive to solve. In this work, we propose an intermediate solution to resolve the issue in the framework of evolutionary game theory.

The effectiveness and safety of hemodialysis can be hindered by protein accumulation, mechanical instability of membranes and bacterial infection during the dialytic therapy. Herein, we show that cellulose acetate membranes modified with the low-fouling polymers (namely polyvinylpyrrolidone and polyethylene glycol), followed by the in situ reduction of different densities of silver oxide(I) nanoparticles, can effectively address these limitations. These improvements comprise the enhanced resistance to the protein fouling, improved antimicrobial capabilities against S.
