Organicphosphorus is a ubiquitous pesticide that has potential hazards to human health and environmental well-being. Therefore, the precise identification of residues of organophosphorus pesticides (OPs) emerges as an urgent necessity. A ratiometric fluorescent sensor for the detection of OPs by leveraging the catalytic activities of Ce and Ce on the two fluorescent substrates 4-Methylumbelliferyl phosphate (4-MUP) and o-phenylenediamine (OPD) correspondingly was designed.

The atmospheric concentration of carbon dioxide (CO2) has fluctuated throughout Earth's history. However, the role of CO2 in prebiotic chemistry has predominantly been limitedly postulated as a C1 precursor, which can be reduced to carbon monoxide or methane mimicking the Wood-Ljungdahl pathway. Herein we present neglected roles of CO2 as an active promoter in accessing biologically important C3-builidng blocks such as lactate, via redox-economic reaction cycles from cyanide (C1) and acetaldehyde (C2).

Methods: We used a systematic analysis design using data from the Global Burden of Disease Study 2019.
The role of government in helping SMEs to access finance: An evolutionary game modeling and simulation approach.
PLoS One
December 2024
School of Intellectual Property, Jiangsu University, Zhengjiang, Jiangsu Province, China.
Purpose: This study aims to delineate the operating system of a strategic game model involving three core financial actors-government, banks, and guarantee institutions, with a focus on their collective impact on system evolution towards sustainable SME financing.
Methodology: Utilizing numerical simulations informed by dynamic equation constraints and optimal equilibrium states, this paper abstracts the strategic behaviors of system constituents, constructing a game model to predict and analyze system evolution within various operational contexts.
Results: The simulation experiments reveal the critical role of quality risk information and responsible actor behavior in maintaining low default rates and fostering a sustainable financial system.
Impact of the COVID-19 pandemic on lung cancer diagnosis in northern Poland-addressing the COVID-19 debt.
PLoS One
December 2024
Department of Water Resources, Climatology and Environmental Management, University of Warmia and Mazury in Olsztyn, Olsztyn, Poland.
Introduction: Lung cancer, one of the leading causes of death due to neoplasms, requires prompt diagnosis and immediate treatment. The COVID-19 pandemic affected healthcare systems worldwide, having adverse effects on all aspects, particularly on the fate of patients with suspected neoplastic diseases. Limited access to healthcare, disruptions in regular operations (reassigning roles to some wards), postponed hospital admissions, prolonged diagnostic processes, and other factors have collectively led to the phenomenon known as COVID-19 debt.
