Sex differences of post-Covid patients undergoing outpatient pulmonary rehabilitation
ConclusionBoth subjective symptoms such as fatigue and dyspnea and objective impairment in performance in pulmonary function were more frequently observed among women. Despite improvement throughout OPR in both women and men, the sex-gap in symptom load could not be closed as women less often achieved remission from functional impairment due to PCS. Intensified treatment of these symptoms should be considered in women undergoing rehabilitation for PCS. (Source: Biology of Sex Differences)

Elucidating effects of the environmental pollutant benzo[a]pyrene [BaP] on cardiac arrhythmogenicity
Environmental pollution causes cardiovascular disease, heart failure, and arrythmias [1 –4]. Wildfire emissions are a complex mixture composed of particulate matter (PM), carbon monoxide, methane, nitrous oxide, and polyaromatic hydrocarbons, among others [5], which are linked to arrhythmias [6]. Benzo[a]pyrene is a polyaromatic hydrocarbon and known carcinogen in animal models and i s implicated in breast cancer, lung cancer, liver cancer, and skin cancer [7]. Therefore, the further impact of BaP on the cardiovascular system merits further investigation. (Source: Journal of Molecular and Cellular Cardiology)

Dynamic trend of lung fluid movement during exercise in heart failure: From lung imaging to alveolar-capillary membrane function
In chronic heart failure (HF), exercise-induced increase in pulmonary capillary pressure may cause an increase of pulmonary congestion, or the development of pulmonary edema. We sought to assess in HF patients the exercise-induced intra-thoracic fluid movements, by measuring plasma brain natriuretic peptide (BNP), lung comets and lung diffusion for carbon monoxide (DLCO) and nitric oxide (DLNO), as markers of hemodynamic load changes, interstitial space and alveolar-capillary membrane fluids, respectively.

CO2 Valorization in Deep Eutectic Solvents
ChemSusChem. 2024 Apr 17:e202400197. doi: 10.1002/cssc.202400197. Online ahead of print.ABSTRACTThe deep eutectic solvent (DES) has emerged in recent years as a valuable medium for converting CO2 into valuable chemicals because of its easy availability, stability, and safety, and its capability to dissolve carbon dioxide. CO2 valorization in DES has evolved rapidly over the past 20 years. As well as being used as solvents for acid/base-promoted CO2 conversion for the production of cyclic carbonates and carbamates, DESs can be used as reaction media for electrochemical CO2 reduction for formic acid and CO. Among these produ...

Development and Performance Evaluation of Biomass-Based Injera Baking Gasifier Stove: A Case Study of Clean Cooking Technologies in Ethiopia
ScientificWorldJournal. 2024 Apr 8;2024:1524398. doi: 10.1155/2024/1524398. eCollection 2024.ABSTRACTThe primary energy source in Ethiopia is biomass. Over 80% of Ethiopians are rural dwellers who rely on biomass energy for lighting and cooking. In most parts of Ethiopia, injera is traditionally baked using an open fire, a three stone, or a device using woody biomass. These baking stoves have very low efficiency and consume a significant amount of fuel. Moreover, these traditional baking stoves have released large amounts of indoor air pollution, which has led to different types of health-related risks, especially for wome...

CO oxidation mechanism of silver-substituted Mo/Cu CO-dehydrogenase. Analogies and differences to the native enzyme
In this study, we employed QM/MM calculations to investigate whether the reaction mechanism of the silver-substituted enzyme is similar to that of the native enzyme. Our results suggest that the Ag-substituted enzyme can oxidize CO and release CO2 following the same reaction steps as the native enzyme, with a computed rate-limiting step of 10.4 kcal/mol, consistent with experimental findings. Surprisingly, lower activation energies for C-O bond formation have been found in the presence of silver. Furthermore, comparison of rate constants for reduction of copper- and silver-containing enzymes suggests a discrepancy in the t...

From a dirty breath to atherosclerosis: Ozone pollution and neutrophil extracellular traps (NETs)
Exposure to ambient ozone in healthy individuals (shown in the magnified alveolus, including the transfer of ozone via the alveolar-capillary membrane and the contact with circulating neutrophils) associates with an elevation in the pro-atherogenic immunothrombotic pathway of NETosis. Precise mechanisms, and the role of concomitant pollutants remain unknown. Abbreviations: particulate matter (PM), ultrafine particles (UFP), sulphur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), neutrophil extracellular traps (NETs), and red blood cells (RBC).

Roles of Nutrients in the Brain Development, Cognitive Function, and Mood of Dogs and Cats
Adv Exp Med Biol. 2024;1446:177-202. doi: 10.1007/978-3-031-54192-6_8.ABSTRACTThe brain is the central commander of all physical activities and the expression of emotions in animals. Its development and cognitive health critically depend on the neural network that consists of neurons, glial cells (namely, non-neuronal cells), and neurotransmitters (communicators between neurons). The latter include proteinogenic amino acids (e.g., L-glutamate, L-aspartate, and glycine) and their metabolites [e.g., γ-aminobutyrate, D-aspartate, D-serine, nitric oxide, carbon monoxide, hydrogen sulfide, and monoamines (e.g., dopamine, norep...

Analysis of a Serious Adverse Reaction of Pulmonary Fibrosis Caused by Dronedarone
CONCLUSIONS: It is recommended that clinicians monitor the diffusion capacity of carbon monoxide and lung ventilation function of patients before and after using dronedarone for treatment. For patients with a history of amiodarone exposure, intermittent monitoring of chest X-rays and lung function is necessary. If lung function decreases, dronedarone should be immediately discontinued.PMID:38617895 | PMC:PMC11015333 | DOI:10.1016/j.curtheres.2024.100743 (Source: Clinical Lung Cancer)
