Single-Inhaler Proposal for Rescue in Acute Allergic Asthma Crises
Published on 2025-02-27 by Paula Priscila Correia Costa, Stefanie Bressan Waller, H�lef Herbet Ramos, Belarmino Eug�nio Lopes Neto, Wesley Lyeverton Correia Ribeiro @MDPI
Abstract: Allergic asthma is characterized by chronic airway inflammation and recurrent bronchial hyperreactivity, highlighting the need for rapid therapeutic interventions during acute crises. This study aimed to assess the potential of a single-dose administration of the ruthenium nitrosyl complex cis-[Ru(bpy)2(2-MIM)(NO)](PG6)3 (named as FOR811A) as a fast-acting treatment in a murine model of allergic asthma. Female Swiss mice were sensitized with ovalbumin for the induction of asthma and subjected to[...]
Our summary: Assessment of FOR811A as a potential rapid therapeutic intervention in allergic asthma crises using a murine model, showing modulation of Th2 immune response and potential for smooth muscle relaxation.

The Effects of 4-Week Respiratory Muscle Training on Cardiopulmonary Parameters and Cognitive Function in Male Patients with OSA
Published on 2025-02-26 by Vasileios T. Stavrou, George D. Vavougyios, Glykeria Tsirimona, Stylianos Boutlas, Marinela Santo, Georgios Hadjigeorgiou, Panagiotis Bargiotas, Konstantinos I. Gourgoulianis @MDPI
Abstract: The aim of this study was to evaluate the effect of a 4-week respiratory muscle training (RMT) intervention versus continuous positive airway pressure (CPAP) on cardiorespiratory parameters and cognitive function in patients with OSA. Twenty-eight male patients with OSA were divided into two groups (RMTgroup n = 14 and CPAPgroup n = 14) and we recorded cardiopulmonary parameters and completed the questionnaires for cognitive impairment (MoCA) and sleep quality (PSQI) before and after 4 weeks. We[...]
Our summary: Effects of 4-week respiratory muscle training on cardiopulmonary parameters and cognitive function in male patients with OSA, comparing RMT intervention vs CPAP, showing improvements in breathing reserve, oxygen breathing, cognitive function, and sleep quality.

Measuring Model Parameter Setting Errors’ Effects in the Control of an Order 4 Underactuated System
Published on 2025-02-23 by Awudu Atinga, Kriszti�n K�si, J�zsef K. Tar @MDPI
Abstract: In the control-based approach of medical treatment of various illnesses such as diabetes mellitus, certain angiogenic cancers, or in anesthesia, the starting point used to be some “patient model” on the basis of which the appropriate administration of the drugs can be designed. The identification of the “patient model’s parameters” is always a hard and sometimes unsolvable mathematical task. Furthermore, these parameters have [...]
Our summary: Investigating the effects of model parameter setting errors in the control of an order 4 underactuated system using a variant of Fixed Point Iteration-Based Adaptive Controllers. The study introduces a parameter estimation error significance metric to estimate the consequences of deficiencies in the model and explores the use of a rotational block for multidimensional orthogonal matrix creation. The method is exemplified on a 2 degree of freedom under-actuated nonlinear system with relative order 4, showing reliable parameter sensitivity estimation metrics.

Demonstration of Polyethylene Nitrous Oxide Catalytic Decomposition Hybrid Thruster with Dual-Catalyst Bed Preheated by Hydrogen Peroxide
Published on 2025-02-18 by Seungho Lee, Vincent Mario Pierre Ugolini, Eunsang Jung, Sejin Kwon @MDPI
Abstract: Although various studies on nitrous oxide as a prospective green propellant have been recently explored, a polyethylene nitrous oxide catalytic decomposition hybrid thruster was barely demonstrated due to an inordinately high catalyst preheating time of a heater, which led to the destruction of components. Therefore, hydrogen peroxide was used as a preheatant, a substance to preheat, with a dual-catalyst bed. The thruster with polyethylene (PE) as a fuel, N2O as an oxidizer, H2O2 as the preheata[...]
Our summary: Demonstration of Polyethylene Nitrous Oxide Catalytic Decomposition Hybrid Thruster with Dual-Catalyst Bed Preheated by Hydrogen Peroxide. Use of hydrogen peroxide as preheatant in a dual-catalyst bed for a polyethylene nitrous oxide thruster to overcome high catalyst preheating time issues and prevent component destruction. Establishment of optimal preheatant and oxidizer supply times to maintain stable post-combustion chamber pressure and catalyst bed temperature.

A Computational Multiphysics Study of a Satellite Thruster
Published on 2025-02-14 by Marcello A. Lepore, Marzio Piller, Mario Guagliano, Angelo R. Maligno @MDPI
Abstract: This work concerns a study of the thermomechanical behaviour of a commercial thruster for aerospace use. The thruster, operated using a bipropellant liquid mixture, is used for the motion and in-orbit altitude control of small telecommunications satellites. The mixture used in the combustion process is composed of propylene and nitrous oxide, while the wall of the thruster is made of PH15-5 stainless steel. A computational fluid dynamics analysis of conjugate heat transfer determines the spatial[...]
