The reactivity of CeO2 towards MoO3 in air atmosphere – reinvestigation
Authors: Bosacka Monika , Filipek Elżbieta , Ambroziak Barbara , Blonska-Tabero Anna 
Published: April 2024

AbstractIt is known that both the type and possibilities of application of cerium molybdates(VI) largely depend on the methods of their synthesis. Despite this, information on the type of molybdates(VI) formed as a result of a waste-free and environmentally friendly reaction occurring in the solid state between CeO2 and MoO3 in the air atmosphere, are divergent. The conducted research indicates that CeO2 and MoO3 react in air and in the temperature range of 500–650 °C to form two compounds, i.e. Ce5Mo8O32 and/or Ce2Mo4O15. Only the Ce5Mo8O32 compound, for the first time, was obtained as a pure phase. The synthesis of Ce5Mo8O32 takes place through an intermediate stage. In this stage, with the evolution of oxygen, the compound Ce2Mo4O15 is formed, which then reacts with excess CeO2 to Ce5Mo8O32. The obtained compound was characterized by XRD, DTA–TG, FTIR and UV–Vis/DRS methods. Ce5Mo8O32 has a green-olive colour and a density of 4.82 ± 0.05 g cm−3. It was found that this compound melts incongruently at the temperature of 960 ± 5 °C with the separation of solid CeO2. The value of the energy gap Eg ~ 2.59 eV allows the Ce5Mo8O32 compound to be classified as a semiconductor. The previously unknown properties of the compound with mixed cerium valence (Ce

Abstract
Context
Elucidating how demography and contemporary landscape features regulate functional connectivity is crucial to implementing effective conservation strategies. We assessed the impacts of landscape features on the genetic variation of a locally endangered carnivore, the leopard cat (Prionailurus bengalensis) in Taiwan.

Objectives
We aim to evaluate the association between genetic structure and landscape features. We further predicted the changes in genetic diversity and suitable habitats in the future.

Methods
We genotyped 184 leopard cats in western Taiwan using 12 nuclear microsatellites and a mitochondrial marker. We applied a landscape optimization procedure with two genetic distances to identify major genetic barriers and employed ecological niche modeling to predict the future distribution of the leopard cat.

Results
Bayesian demographic inferences revealed a dramatic population decline for all leopard cat populations in Taiwan. Genetic clustering and resistance surface modeling supported that the population connectivity was influenced by highways and high elevation. Niche modeling indicated low temperature was one of the primary factors limiting the occurrence of leopard cats that may inhibit their movement in high elevations. We predicted the suitable habitats of leopard cats would shrink northward and towards higher altitudes with rugged topography in response to global warming.

Conclusions
Our study provided genetic evidence that leopard cats in Taiwan had undergone a dramatic population decline that may be associated with anthropogenic impacts. We also inferred the anthropogenic linear feature compromised the connectivity and persistence of leopard cats in human-mediated landscapes. Our finding serves as a model for landscape genetic studies of island carnivores in subtropical regions.
Seasonal bee communities vary in their responses to resources at local and landscape scales: implication for land managers

Published: April 2024

Abstract
Context
There is great interest in land management practices for pollinators; however, a quantitative comparison of landscape and local effects on bee communities is necessary to determine if adding small habitat patches can increase bee abundance or species richness. The value of increasing floral abundance at a site is undoubtedly influenced by the phenology and magnitude of floral resources in the landscape, but due to the complexity of measuring landscape-scale resources, these factors have been understudied.

Objectives
To address this knowledge gap, we quantified the relative importance of local versus landscape scale resources for bee communities, identified the most important metrics of local and landscape quality, and evaluated how these relationships vary with season.

Methods
We studied season-specific relationships between local and landscape quality and wild-bee communities at 33 sites in the Finger Lakes region of New York, USA. We paired site surveys of wild bees, plants, and soil characteristics with a multi-dimensional assessment of landscape composition, configuration, insecticide toxic load, and a spatio-temporal evaluation of floral resources at local and landscape scales.

Results
We found that the most relevant spatial scale and landscape factor varied by season. Early-season bee communities responded primarily to landscape resources, including the presence of flowering trees and wetland habitats. In contrast, mid to late-season bee communities were more influenced by local conditions, though bee diversity was negatively impacted when sites were embedded in highly agricultural landscapes. Soil composition had complex impacts on bee communities, and likely reflects effects on plant community flowering.

Conclusions
Early-season bees can be supported by adding flowering trees and wetlands, while mid to late-season bees can be supported by local addition of summer and fall flowering plants. Sites embedded in landscapes with a greater proportion of natural areas will host a greater bee species diversity.
Universal shape replication via self-assembly with signal-passing tiles
Authors: Alseth Andrew , Hader Daniel , Patitz Matthew J. 
Published: April 2024

AbstractIn this paper, we investigate shape-assembling power of a tile-based model of self-assembly called the Signal-Passing Tile Assembly Model (STAM). In this model, the glues that bind tiles together can be turned on and off by the binding actions of other glues via “signals”. Specifically, the problem we investigate is “shape replication” wherein, given a set of input assemblies of arbitrary shape, a system must construct an arbitrary number of assemblies with the same shapes and, with the exception of size-bounded junk assemblies that result from the process, no others. We provide the first fully universal shape replication result, namely a single tile set capable of performing shape replication on arbitrary sets of any 3-dimensional shapes without requiring any scaling or pre-encoded information in the input assemblies. Our result requires the input assemblies to be composed of signal-passing tiles whose glues can be deactivated to allow deconstruction of those assemblies, which we also prove is necessary by showing that there are shapes whose geometry cannot be replicated without deconstruction. Additionally, we modularize our construction to create systems capable of creating binary encodings of arbitrary shapes, and building arbitrary shapes from their encodings. Because the STAM is capable of universal computation, this then allows for arbitrary programs to be run within an STAM system, using the shape encodings as input, so that any computable transformation can be performed on the shapes. This is the full version, containing all construction and proof details, of a previously published extended abstract version that had most details omitted.
The self-reinforcing nature of joint action
Authors: Alonso Facundo M. 
Published: April 2024

AbstractShared intention normally leads to joint action. It does this, it is commonly said, only because it is a characteristically stable phenomenon, a phenomenon that tends to persist from the time it is formed until the time it is fulfilled. However, the issue of what the stability of shared intention comes down to remains largely undertheorized. My aim in this paper is to remedy this shortcoming. I argue that shared intention is a source of moral and epistemic reasons, that responsiveness to such reasons on the part of each individual reinforces her own relevant attitudes, and that this enhances the stability of the shared intention as a whole. We thus discover an important self-reinforcing and stability-enhancing mechanism at the heart of shared intention and action. It follows from this proposal that the psychological commitment that an individual exhibits in joint action is normally a function not only of her own participatory intention, as often maintained, but also of her endorsement of the reasons created by her group’s shared intention to so act.

Published: April 2024

AbstractIndole alkaloids, predominantly found in plants, are a large group of natural product-derived compounds characterized by a remarkable chemical diversity associated with significant biological properties. Among these, terpenoid indole alkaloids are the largest group of secondary metabolites. Tabernaemontana species (Apocynaceae) are widely distributed in tropical and subtropical regions of the world and used in traditional medicine to treat a variety of illnesses, including tumours. These species biosynthesize large quantities of structurally complex monoterpene indole and bisindole alkaloids. Given the compelling biological properties of indole alkaloids, the phytochemical study of Tabernaemontana species has been widely addressed to identify potential anticancer compounds. Several indole alkaloids have shown antiproliferative effect due to different mechanisms, namely by inducing apoptosis or arresting cell cycle, in diverse cancer cell lines, including multidrug-resistant phenotypes. This review primarily aims to underscore the anticancer activity of indole and bisindole alkaloids isolated from several Tabernaemontana species. Moreover, our recent contributions to the field are also highlighted, focusing on the study of Tabernaemontana elegans. The anticancer evaluation, namely the reversion of P-glycoprotein-mediated multidrug resistance, of two sets of monoterpene indole alkaloid derivatives, obtained by modification of some functional groups of two major monoterpene indole alkaloids, is reviewed, as well as the results obtained for a derivative that targeted homologous recombination DNA repair defects.

Published: April 2024

AbstractThe challenge of antimicrobial resistance requires new solutions, and Rhodiola sp. is a promising candidate due to its rich medicinal history. This review focuses on Rhodiola sp., especially R. rosea, highlighting its phytochemical constituents, such as salidroside, rosavins, and other phenolics, and their antimicrobial potential. We investigate the efficacy of Rhodiola sp. against various pathogenic bacteria, suggesting their value in combating antimicrobial resistance. Additionally, Rhodiola compounds are being investigated both as direct antimicrobials and as resistance modifiers that increase the efficacy of antibiotics. Rhodiola extracts and salidroside modulate gut microbiota, thereby affecting health and physiological and metabolic disorders. This illustrates the comprehensive therapeutic potential of Rhodiola sp. We emphasize the importance of understanding the complex interactions between Rhodiola phytochemicals, their antimicrobial effects, and their effects on gut microbiota as well as the need for in-depth research. Further studies will be crucial for the development of holistic treatment approaches. Finally, Rhodiola sp. is highlighted as an important natural resource in the fight against microbial pathogens and antibiotic resistance. Research on Rhodiola sp. should continue to further unravel pharmacological and health-promoting potential and thus address an important public health challenge.
Metrics in biodiversity conservation and the value-free ideal
Authors: Bocchi Federica 
Published: April 2024

AbstractThis paper examines one aspect of the legacy of the Value-Free Ideal in conservation science: the view that measurements and metrics are value-free epistemic tools detached from ideological, ethical, social, and, generally, non-epistemic considerations. Contrary to this view, I will argue that traditional measurement practices entrenched in conservation are in fact permeated with non-epistemic values. I challenge the received view by revealing three non-epistemic assumptions underlying traditional metrics: (1) a human-environment demarcation, (2) the desirability of a people-free landscape, and (3) the exclusion of cultural diversity from biodiversity. I also draw a connection between arguments for retaining traditional metrics to “scientific colonialism,” exemplified by a fortress conservation model. I conclude by advocating for abandoning the myth of the intrinsic value-freedom of measurement practices and embracing metrics aligned with societal and scientific goals.
Comprehensive evaluation of genetic and acquired thrombophilia markers for an individualized prediction of clinical thrombosis in patients with lymphoma and multiple myeloma

Published: April 2024

AbstractPatients diagnosed with lymphoma or multiple myeloma are at elevated risk of venous thromboembolism (VTE). Optimum risk stratification and effective thromboprophylaxis can only be achieved through the development of a multiple-specific risk score that successfully captures all aspects of the heterogeneous prothrombotic environment existing in these patients. Our aim was to identify risk factors for thrombosis and suggest an improved tool combining clinical data, thrombo-inflammatory biomarkers and genetic (Thrombo inCode® test) variables for predicting thrombotic risk in patients with lymphoma and multiple myeloma. A prospective longitudinal study was conducted on newly-diagnosed lymphoma and multiple myeloma patients who presented at our institution between February 2020 and January 2021. The study included 47 patients with lymphoma and 16 patients with multiple myeloma. We performed a follow-up of 1 year or until September 2021. The incidence of venous thrombosis and associated risk factors were analysed, including the genetic Thrombo inCode® test. Khorana and ThroLy scores for lymphoma patients and IMPEDE VTE score for myeloma patients were calculated. At a median follow-up of 9.1 months, VTE incidence was 9.5% (6/63), with 4 and 2 patients with lymphoma and myeloma who developed the events, respectively. Univariate analysis showed that the incidence of thrombosis was significantly higher in patients with ECOG ≥ 2 and prior immobility. Median factor VIII levels were significantly higher in patients with thrombosis (with increased values in all of them). Moreover, there was a trend in genetic variant rs5985 (factor XIII) as a protective factor, and a trend to higher thrombotic risk in patients with factor V Leiden, rs2232698 variant (serpinA10), low total protein S activity, elevated D-dimer, aggressive lymphoma and treatment with dexamethasone. The results of our study demonstrate promise for the potential use of widely accessible markers to increase precision in risk prediction for VTE in patients with lymphoma and multiple myeloma, particularly ECOG ≥ 2, immobility and higher factor VIII levels, as well as lymphoma aggressiveness, treatment with dexamethasone and the haemostatic biomarkers D-dimer and total protein S activity. Additionally, genetic variants factor V Leiden, serpinA10 rs2232698 and factor XIII-A Val34Leu warrant further investigation for use in the research setting.

Published: April 2024

AbstractMultimorbidity, i.e., two or more non-communicable diseases (NCDs), is an escalating challenge for society. Venous thromboembolism (VTE) is a common cardiovascular disease and it is unknown which multimorbidity clusters associates with VTE. Our aim was to examine the association between different common disease clusters of multimorbidity and VTE. The study is an extended (1997–2015) cross-sectional Swedish study using the National Patient Register and the Multigeneration Register. A total of 2,694,442 Swedish-born individuals were included in the study. Multimorbidity was defined by 45 NCDs. A principal component analysis (PCA) identified multimorbidity disease clusters. Odds ratios (OR) for VTE were calculated for the different multimorbidity disease clusters. There were 16% (n = 440,742) of multimorbid individuals in the study population. Forty-four of the individual 45 NCDs were associated with VTE. The PCA analysis identified nine multimorbidity disease clusters, F1-F9. Seven of these multimorbidity clusters were associated with VTE. The adjusted OR for VTE in the multimorbid patients was for the first three clusters: F1 (cardiometabolic diseases) 3.44 (95%CI 3.24–3.65), F2 (mental disorders) 2.25 (95%CI 2.14–2.37) and F3 (digestive system diseases) 4.35 (95%CI 3.63–5.22). There was an association between multimorbidity severity and OR for VTE. For instance, the occurrence of at least five diseases was in F1 and F2 associated with ORs for VTE: 8.17 (95%CI 6.32–10.55) and 6.31 (95%CI 4.34–9.17), respectively. In this nationwide study we have shown a strong association between VTE and different multimorbidity disease clusters that might be useful for VTE prediction.

Urban biodiversity and design in time of (post)pandemics: research perspectives from URBIO international network
Authors: Dushkova Diana , Ignatieva Maria , Konstantinova Anastasia , Nilon Charles , Müller Norbert 
Published: April 2024

AbstractReflecting on the insights from research development within Urban Biodiversity and Design Network (URBIO), this paper attempts to link the consequences of current global changes (ongoing urbanization, biodiversity loss, land-use changes, globalization, etc.) to the emergence and outbreaks of the COVID-19 pandemic. It analyses the main outcomes of the URBIO webinar (December 2021) and the URBIO conference (November 2022) and the results of the questionnaire survey among the URBIO experts on the impact of COVID-19 on the biodiversity, design and society in their local contexts as well as on the ongoing and future URBIO research directions. The survey also enabled to explore and assess a wide diversity of human-nature interactions as well as the novel actions and adaptation strategies established to have positive outcomes for both humans and nature. The results revealed the following aspects associated with the COVID-19 pandemic: silence, social distancing, isolation, conflict ideologies, and declined recreational and other human activities. Experts noticed the increase of urban green space visitation and interest in nature. The majority of the experts confirmed the impact (both positive and negative) of the COVID-19 on biodiversity and environment. General positive aspects refer to the value/significance of nature and biodiversity/wildlife and especially the contact with nature (“time outdoor”, “time spent with family”, “inspiration from nature” and “enjoying nature”). The positive consequence of the COVID-19 measures was also the improvement of wildlife habitats and the increase of spontaneous flora as well as fauna species. Experts confirmed the lower/decreased level of pollution, noise, traffic, light, anthropogenic pressure/impact, number of tourists, vehicles as well as less garbage. The analysis of leading research themes among the URBIO conference participants confirmed that the biggest number of presenters and participants were on the topic of biodiversity integration in urban planning, green infrastructure, and landscape design projects. Another popular theme was ecological restoration and urban wildlife and plant biodiversity. One particular research direction that emerged recently and clearly pronounced at URBIO 2022 was urban biodiversity in times of climate change and post-pandemics.

AbstractThe World Health Organization (WHO) has established as a criterion of parasitological quality for irrigation water, ≤ 1 helminth egg/liter, which guarantees the safety in agricultural products. In this study, the presence of parasites in surface water used for irrigation of crops (n = 96) and vegetables (celery and lettuce) (n = 120), from the Former La Ramada irrigation district, was evaluated using conventional and molecular parasitological methods. Our findings showed contamination of irrigation systems in the study area with domestic wastewater, demonstrated by the presence of Ancylostomatidae eggs,Ascarisspp.,Hymenolepisspp.,Trichurisspp.,Capillariaspp.,Giardiaspp. cysts, and oocysts ofToxoplasma gondiiandCryptosporidiumspp. A prevalence of 33% and 23.3% was calculated for helminths and protozoa, respectively in vegetables, representing a possible risk to human and animal health in relation to these parasites. These findings show the need for continuous monitoring of the water quality used for crop irrigation, as well as the safety of food, taking into account the values established in national and international regulations.

Published: April 2024

AbstractIn the current study, the catalyst for the decolorization of methyl orange (MO) was developed HAp-rGO by the aqueous precipitation approach. Then, bismuth(0) nanoparticles (Bi NPs), which expect to show high activity, were reduced on the surface of the support material (HAp-rGO). The obtained catalyst was characterized by scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) techniques. The parameters that remarkably affect the decolorization process (such as time, initial dye concentration, NaBH4 amount, and catalyst amount) have been examined by response surface methodology (RSM), an optimization method that has acquired increasing significance in recent years. In the decolorization of MO, the optimum conditions were identified as 2.91 min, Co: 18.85 mg/L, NaBH4 amount: 18.35 mM, and Bi/HAp-rGO dosage: 2.12 mg/mL with MO decolorization efficiency of 99.60%. The decolorization process of MO with Bi/HAp-rGO was examined in detail kinetically and thermodynamically. Additionally, the possible decolorization mechanism was clarified. The present work provides a new insight into the use of the optimization process for both the effective usage of Bi/HAp-rGO and the catalytic reduction of dyes.
