description: Background: Microplastics (MPs) have been found in all types of aquatic ecosystems, posing a threat to the environment, wildlife and human health [1-3]. Although rivers act as marine litter pipelines to the ocean, estuaries can act as buffer zones preventing garbage from reaching the sea, thus, acquired data on those ecosystems contribute to a better understanding on the entry of litter into the ocean from terrestrial sources [4]. As such, knowledge of estuarine hydrodynamics is critical to understand problems such as water quality, residence time and dispersion rate of pollutants [5]. In addition, scientific data on MPs in Portugal aquatic ecosystems is scarce. Objective: This study aimed to: 1) evaluate and characterize MPs in the Ave Estuary water column, and 2) identify the potential sources, and analyse the main hydrodynamic patterns and the water residence time to understand the MPs transport patterns. Methods: Short-term campaigns were performed to measure vertical profiles of velocity, salinity, temperature and pH in the Ave Estuary. MPs particles were sampled using a planktonic horizontal trawl, processed following standardized protocols [6], identified, measured, and sorted by shape and colour [7,8]. Results: This study revealed a clear stratification of the Ave Estuary, as well as considerable contamination by MPs (annual average density of 63.1 ± 4.7 MPs/m³) with a significant prevalence of blue (34%) fragments (53%), measuring between 0.5 mm and 1 mm (42%). Conclusions: The obtained results showed a very strong seasonal pattern, and pointed to public litter, tourism and fishing activities as potential main sources of MPs in the study area and to an urgent need for adequate management of MPs and of marine and coastal ecosystems. This study represents a contribution to the pressing need of temporal and spatial monitoring on MPs pollution in estuaries and other coastal ecosystems.

description: In the quest to find quantum spin liquids, layered cobalt oxides Na2Co2TeO6 and Na3Co2SbO6 have been proposed as promising candidates for approximating the Kitaev honeycomb model. Yet, their suitability has been thrown into question due to observed long-range magnetic order at low temperatures and indications of easy-plane, rather than Kitaev-type, spin anisotropy. Here we use muon spin relaxation to reveal an unexpected picture: contrary to the anticipated static nature of the long-range order, the systems show prevalent spin dynamics with spatially uneven distribution and varied correlation times. This underlines that the magnetic ground states cannot be solely described by the long-range order, suggesting a significant role of quantum fluctuations. Our findings not only shed new light on the complex physics of these systems but also underscore the need for a refined approach in the search for realizable quantum spin liquids.

description: Talk presented at the the 39th International Symposium on Lattice Field Theory by Andreas Athenodorou, based on the 'Survey on lattice data analysis, presentation, and curation practices', the results of which can be found in https://doi.org/10.5281/zenodo.6980070 Abstract: Open science aims to make scientific research processes, tools and results accessible to all scientific communities, creating trust in science and enabling digital competences to be realized in research, leading to increased innovation. It provides standard and transparent pathways to conducting research and fosters best practices for collecting, analysing, preserving, sharing and reusing data, software, workflows and other outputs through collaborative networks. Open Science appears to becoming the norm with its applications spanning throughout the whole research cycle of a project. The importance of making Open Science a reality is reflected in the policy and implementation actions of the European Commission incorporated in research and innovation funding programmes (FP7, Horizon 2020, Horizon Europe) and the development of the European Open Science Cloud (EOSC) as it improves the quality, efficiency and responsiveness of research. EOSC will enable researchers across disciplines and countries to store, curate and share data under a common policy framework with rules of participation and pre-defined set of technical specifications that are expected to help shape the “Internet of FAIR data and services” in Europe. In this talk we will present the basic Open Science principles explaining briefly best practices for materialising open science. Subsequently, we will present the results of the landscaping survey of Open Science in the Lattice Gauge Theories community (https://latticesurvey.hpcf.cyi.ac.cy/index.php/157898). Finally, we will provide directions in which the LGT community could move in order to enhance Openness and FAIRness (Finability, Accessibility, Interoperability, Reusability) in Science.

description: Background: Raman spectroscopy (RS) is a sensitive technique used for gathering chemical and molecular data, resulting in a biochemical fingerprint of the sample. This method is label-free and provides rapid detection [1]. Furthermore, it has proven invaluable in the forensic, biological and medical contexts [2]. It is also suitable for investigations assessing toxic effects of some chemicals, enabling swift acquisition of extensive organism-specific information. Its application to zebrafish serves various purposes, including physiological [3] and toxicological evaluation [4]. However, no base characterization of this organism has been provided in such studies that could be useful for the planning of experiments aiming at diagnosing and follow-up environmental contamination. Objective: The present study aimed to characterize the developmental Raman profile of different zebrafish organs, by drawing a baseline analysis of embryos and larvae up to 168 hpf. Methods: Different organs or tissues were examined daily from 24 to 168 hours post-fertilization, according to their time window of emergence in the embryo, including the heart, muscle, brain, iris, swim bladder, and melanocytes. Chemometric analysis, employing partial least-squares discriminant analysis (PLS-DA), was employed to characterize the organs and ascertain the contribution of spectral bands to their discrimination. Results: A total of 117 spectral bands were identified, with 24 demonstrating robust, systematic representation. The bands were found in the 223 to 3431 cm-1 spectral range; most of them were related to amino acids and relevant macromolecules, such nucleic acids, proteins and lipids. Only three bands were found to be common to all recorded organs and tissues. PLS-DA generated distinct spectral fingerprints for each organ, illustrating variations over early development. Conclusions: Overall, the work developed provided a clear baseline profile of organs and tissues of zebrafish embryos and larvae, identifying Raman bands of expeditious acquisition and their expected variation over different developmental stages, before and after hatching.

NAVIGATING DIVERSITY: SRI AUROBINDO'S FEDERAL MODEL FOR INDIAN GOVERNANCE AND NATIONAL UNITY
Creators: name: Dr. Neeraj Kumar
Publisher: name: Zenodo
Year: 2024

description: This paper critically examines Sri Aurobindo’s contributions to Indian nationalism, focusing on his ideas of national reconstruction, which were deeply rooted in spiritual, cultural, and political thought. Sri Aurobindo's political philosophy developed during a time of significant anti-colonial activity, particularly the Swadeshi and anti-partition movements. His distinctive nationalist ideology emphasized complete independence (Swaraj) as a multidimensional goal that encompassed political, spiritual, and social freedoms. Furthermore, his thoughts on passive resistance, armed struggle, Hindu-Muslim unity, and Sanatana Dharma influenced the broader national movement. This paper explores how Sri Aurobindo’s conception of nationalism and resistance compares with contemporaries like Tilak, Bipin Chandra Pal, and Mahatma Gandhi, and evaluates its relevance in the context of India’s struggle for independence from 1885 to 1947.

description: We investigate the use of 2D black-and-white textures for the visualization of categorical data and contribute a summary of texture attributes, and the results of three experiments that elicited design strategies as well as aesthetic and effectiveness measures. Black-and-white textures are useful, for instance, as a visual channel for categorical data on low-color displays, in 2D/3D print, to achieve the aesthetic of historic visualizations, or to retain the color hue channel for other visual mappings. We specifically study how to use what we call geometric and iconic textures. Geometric textures use patterns of repeated abstract geometric shapes, while iconic textures use repeated icons that may stand for data categories. We parameterized both types of textures and developed a tool for designers to create textures on simple charts by adjusting texture parameters. 30 visualization experts used our tool and designed 66 textured bar charts, pie charts, and maps. We then had 150 participants rate these designs for aesthetics. Finally, with the top-rated geometric and iconic textures, our perceptual assessment experiment with 150 participants revealed that textured charts perform about equally well as non-textured charts, and that there are some differences depending on the type of chart.

description: Background: In the realm of water treatment and public health, the interplay between microorganisms and disinfection processes represents a constant and dynamic challenge [1]. As society strives to ensure the availability of safe and clean water, understanding the factors contributing to bacterial resistance to water disinfection emerges as a critical area of research [1]. Among these factors, the phenomenon of bacterial coaggregation has gained increasing attention for its pivotal role in shaping microbial communities and influencing the effectiveness of disinfection strategies [2]. Objective: This work aims to elucidate the intricate relationship between bacterial coaggregation and resistance to water disinfection. Methods: Biofilms of the emerging drinking water (DW) pathogen Stenotrophomonas maltophilia [3,4] were formed on polyvinyl chloride (PVC) coupons for 7 days and studied for their resistance to sodium hypochlorite disinfection when co-cultured with two strains from the DW context: one exhibiting coaggregation behavior (Delftia acidovorans 005P) and another without coaggregation tendencies (D. acidovorans 009P). Results: It was observed that high doses of free chlorine  (> 10x MBC) were not able to completely kill biofilm bacteria within 30 minutes of disinfection. However, biofilms that combined S. maltophilia with D. acidovorans 005P (coaggregating strain) showed greater resistance to disinfection. In addition, the biofilms that contained the coaggregating strain were also those that presented a greater content of extracellular polymeric substances (EPS), namely proteins and polysaccharides, and a greater thickness. Conclusions: It is known that coaggregation is mediated by protein-saccharide interactions and that in this case, they may be contributing to the biofilm's tolerance to disinfection [1,5]. Thus, understanding the role of bacterial coaggregation in disinfection resistance is pivotal for developing innovative strategies that can effectively combat the persistence of pathogenic microorganisms and safeguard public health in an increasingly complex and interconnected world.

description: Background: Metal-rich nodules in the deep ocean contain significant quantities of high-value metals such as copper, nickel, and cobalt [1]. Mining deep-sea minerals is considered as an alternative to land mining, to reduce environmental effects and gain geopolitical advantages [1,2]. However, this action may expose deep-sea microbes to toxic concentrations of metals such as cadmium (Cd) which are shown to have an impact on metabolic and biogeochemical processes [3,4]. Objective: This study aims to quantify microbial diversity in deep-sea habitats, specifically Pacific Ocean seamounts, while examining the genomic responses caused by various degrees of Cadmium (Cd) exposure. Methods: Sediment samples from Pacific Ocean seamounts were collected, 96h pre-exposed to different concentrations of Cd, and later sequenced with 16S rRNA gene sequencing with Illumina MiSeq. Bioinformatics analysis has been conducted to investigate the taxonomic and functional diversity of microbial communities as well as their genomic responses to metal exposure. Results: According to the initial findings, the microbial communities in all samples were dominated by bacteria, with also the presence of archaea. Diversity in bacterial communities is higher compared to the archaeal groups. Upon completion of the study, we expect to observe a shift in the diversity of microbes found in sediment samples as Cd concentrations increase. Some microbes may be more resistant to Cd and become more abundant, whilst others may become less abundant. Conclusions: Deep-sea mining is expected to have impacts on the microbial communities, possibly hampering the diversity of the communities. A change in microbial diversity can have cascading impacts on the nutrient cycle and the overall health of the ecosystem. Future research should investigate the other aspects of the impacts that can come along with deep-sea mining before the approval of commercial operation.

title: Response Of An Estuarine Ecosystem To Reduced Organic Waste Discharge

Subjects: Pressures, impacts, conservation, and management

description: No abstracts are to be cited without prior reference to the author.Since the mid-19th century large amounts of organic waste were sluiced out into the Ems estuary forming the boarder between Germany and The Netherlands. This waste originated from regional potatoflour and cardboard industry. At that time, the inland water ways were completely anoxic and in the estuary serious oxygen depletion occurred, especially during autumn. The majority of the organic waste entered the estuary in the Dollard, a brackish embayment of the Ems estuary. An intensive sanitation scheme was started in the 1970s, leading to a stepwise reduction of the organic waste load on the estuary. In this paper, the response is described of the benthos living at intertidal mudflats, viz. microphytobenthos (diatoms), meiofauna (nematodes) and macrozoobenthos. The benthos response is described mainly on the basis of data obtained under conditions of high (ca. 1980), intermediate (1987) and greatly reduced (1993) organic waste loading. Reduction of organic loading caused significant changes in abundance and species composition of diatoms and nematodes. Macrobenthic populations recovered from regularly being decimated during the autumnal waste discharges towards a more stable situation. Altogether, the intertidal mudflat benthos changed from being stressed by organic waste loading towards a normal situation of estuarine environmental stress. This was esp[ecially the case at high muddy fllats in the southeast of the Dollard. At mixed sand/mud flats in the centre of the Dollard a response of macrozoobenthos may have been obscured to some extent to the development of the invasive polychaete Marenzelleria cf. wireni.

description: We propose three novel spatial data selection techniques for particle data in VR visualization environments. They are designed to be target- and context-aware and be suitable for a wide range of data features and complex scenarios. Each technique is designed to be adjusted to particular selection intents: the selection of consecutive dense regions, the selection of filament-like structures, and the selection of clusters -- with all of them facilitating post-selection threshold adjustment. These techniques allow users to precisely select those regions of space for further exploration -- with simple and approximate 3D pointing, brushing, or drawing input -- using flexible point- or path-based input and without being limited by 3D occlusions, non-homogeneous feature density, or complex data shapes. These new techniques are evaluated in a controlled experiment and compared with the Baseline method, a region-based 3D painting selection. Our results indicate that our techniques are effective in handling a wide range of scenarios and allow users to select data based on their comprehension of crucial features. Furthermore, we analyze the attributes, requirements, and strategies of our spatial selection methods and compare them with existing state-of-the-art selection methods to handle diverse data features and situations. Based on this analysis we provide guidelines for choosing the most suitable 3D spatial selection techniques based on the interaction environment, the given data characteristics, or the need for interactive post-selection threshold adjustment.

This research aims to describePhenomenological Study of Cryptocurrency Digital Asset Investment in Indonesia in Comparison of Tax Collection Rules and Implementation of Sharia Qanun. Literature review or literature review is a method used in research research. The research method in this study uses normative juridical research methods. The data collection technique used is library research. Data obtained during the research will be analyzed using qualitative descriptive methods. Crypto research results aside from being a transaction tool, crypto is also popular with the public as an investment. One aspect of taxation imposed on crypto assets is Value Added Tax (VAT) and PPh. Views of Islamic economic law andSharia QanunSo several findings can be outlined, including: As a digital financial transaction system, cryptocurrency basically uses relatively new technology, the nature of its legality still needs to be studied in more depth, but it is not a form of violation. In Indonesia itself, the government has not taken a definite stance on the existence of cryptocurrency, so people are still allowed to use it. However, investing in cryptocurrency carries a very high risk because its value can rise or fall drastically and unpredictably.

description: The benefits of construction earthquake resistant buildings are the savings in property damage, injuries, and lives that accrue in the event of an earthquake. The costs are the additional resources required to ensure that buildings are resistant. In certain regions of the U.S., particularly in California, earthquake resistant buildings are commonplace. As we will show, the cost of adding this resistance to buildings is about seven billion dollars in Los Angeles County alone. The purpose of this paper is to present a methodology for estimating these costs as well as the benefits of resistance. The methodology draws upon the economic approach to valuing risks to life, as well as recent engineering and geological studies of earthquakes and the damage they cause. Our results should be useful both to policy makers concerned with whether the current level to precautions taken to mitigate earthquake losses are adequate, and to economists confronted with evaluating the precautions taken by society against natural hazards in general.

description: Background: Glyphosate-based herbicides (GBH) are the most widely used agrochemicals [1]. Earthworms are key soil organisms used as bioindicators and alternative experimental models for studying the immune system [2,3]. Objective: We tested whether agronomic dosages of GBH induce avoidance behavior and alter the immunological profile of earthworms Eisenia andrei. Methods: Adult earthworms (0.318 ± 0.007 g) were divided into four groups and exposed for 48h: Control group (native soil), GBH1.5, GBH3, and GBH6 groups (native soil with GBH at concentrations equivalent to 1.5, 3.0, and 6.0 L/ha, respectively). Under these conditions, we applied the Avoidance Behavior Test (% of animals that escape from contaminated areas) and Acute Toxicity Test. We used glyphosate (Roundup®, Original DI, Monsanto, 44.5% w/v active ingredient) or water (control) in each experimental unit (n=6; 6 animals/experimental unit, 6 replicates each, in a box with 600g of soil, 95% of dystrophic red latosol:5% organic matter). The coelomocytes were collected by a non-invasive method [4]. Results: The highest concentration (GBH6) induced avoidance behavior in earthworms (% avoidance = GBH6 = 83.3±18.2, p=0.01) without modification in the immune profile. Furthermore, there was a reduction in cell viability of the coelomocytes obtained from the GBH6 (p=0.001) and also GBH3 (p=0.01) groups, when the animals had no option to avoid the contaminated area (CTRL: 75.7±18.9%; GBH1.5: 63.7±22%; GBH3: 56.7±29.6%; and GBH6: 56.0±21.4%). Conclusion: The presence of GBH in the soil at a typical agronomic dose (3.0 L/ha) or higher (6.0 L/ha) threatens the immune defense of earthworms and may lead to the loss of the ecological function of soil.

description: Background: Chiral psychoactive substances (PAS) as amphetamine-like substances are among the main group of drugs seized in Europe. The increased attractiveness of these drugs resulted in their widespread occurrence in the environment raising concern about their possible hazardous effects to non-target organisms [1, 2]. PAS metabolism in humans and biodegradation in wastewater treatment plants is stereoselective. Enantiomers of PAS may differ in environmental fate and toxicological effects [2, 3]. Understanding their enantiomer-specific toxicity and sublethal effects using several biomarkers is crucial for an accurate risk assessment of chiral contaminants. Objective: Investigate the potential enantioselective effects of 3,4-methylenedioxymethamphetamine (MDMA) in zebrafish (Danio rerio) embryos. Methods: For zebrafish 96-h assay, 50 fertilized eggs (≈ 3 hpf) were exposed to different concentrations of MDMA racemate and enantiomers ranging from 0.02 to 200 μg/L. Six replicates per test concentration and control were performed and organisms were exposed for 6 days. Embryonic development, malformations, genotoxicity and larvae swimming behaviour parameters were evaluated for MDMA. The range of concentrations for both organisms was selected to include environmental reported levels and higher concentrations to get insights into potential toxicity. Results: Regarding zebrafish, preliminary data showed an enantioselective effect with significant increase in the percentage of developmental malformations at 96 hpf in zebrafish larvae exposed to (S)-MDMA in comparison with (R,S)-MDMA and (R)-MDMA at the lower concentrations. An increase in larvae size was observed in the organisms exposed to the racemate in comparison to the enantiomers. Also, a significant increase in genotoxicity was observed in organisms exposed to racemate. Changes and enantioselective effects were also observed in swimming behaviour, (R)-MDMA inducing a reduction in the distance to the centre of the well compared to (S)-MDMA, and a decrease in inactive time in (S)-MDMA exposed organisms. Conclusions: This study showed the toxicity of MDMA towards zebrafish embryo, and importance of enantiotoxicity studies for a better risk assessment.

description: Background: Aromatic amines are extensively employed in dye, pharmaceutical, pesticide, and polymer manufacturing. These compounds exert environmental impacts, affecting aquatic ecosystems and biodiversity [1]. 3,4-dichloroaniline (3,4-DCA) is a candidate for inclusion in the 4th Watch List of Water Framework Directive due to its presence in aquatic ecosystems and known ecotoxicological effects [2, 3]. Objective: This study aimed to assess the individual and sub-individual chronic effects of 3,4-DCA on Daphnia magna, considering environmental concentrations [0.07 µg/L to 6 µg/L in wastewater treatment plant influents, superficial water (Germany), and effluents (USA), river waters (Portugal and USA) and groundwaters (Portugal) [3]] and previous studies (subchronic exposure). Methods: Chronic exposure (21 days) was conducted with D. magna exposed to a range of ecologically relevant concentrations of 3,4-DCA (≤ 6 µg/L). Different biological responses were evaluated: 1) individual - growth and reproduction; and 2) sub-individual - antioxidant defense and detoxification, energetic metabolism, neurotransmission, and genotoxicity. Results: Significant effects were observed in D. magna following 3,4-DCA exposure. Somatic growth rate increased (≥ 2 µg/L), catalase activity decreased (0.222 µg/L) followed by an increase (6 µg/L), and genetic damage index increased above 0.294 µg/L. The rise in somatic growth may signal resource allocation changes, affecting fitness and reproduction. Catalase activity fluctuation and the absence of significant results in other antioxidant defenses and lipid peroxidation suggest that this enzyme was able to neutralize oxidative stress and damage. Genotoxicity suggests future impacts on population and genetic diversity. Conclusions: This study provides crucial insights into the chronic ecotoxicological effects of 3,4-DCA on D. magna, under ecologically relevant concentrations. It underscores the importance of considering diverse biological endpoints in ecotoxicological assessments. These findings play a pivotal role in assessing the ecological risks associated with aromatic amines, enabling the identification of measures to safeguard global environmental integrity and human health.

description: Background: Electronic cigarettes (E-cigs) and heated tobacco products (HTPs) have gained popularity as alternatives to traditional tobacco products (TTPs), claiming to reduce harm. The carcinogenic properties of chemicals in the smoke of TTPs are widely recognized. However, there is still an incomplete understanding of the different chemicals in E-cigs and HTPs and their toxicity to human cells [1]. Objective: Thus, this study aimed at characterizing and comparing the chemical composition of three different brands of E-cigs, HTPs and TTPs. Methods: We selected the three top-selling brands of E-cigs, HTPs, and TTPs in Portugal, and each brand (n=9) was analyzed in triplicate. Volatile compounds present in all brands were extracted by headspace solid-phase microextraction (HS-SPME) and solvent extraction (dichloromethane). The volatile compounds in the headspace and solvent extracts were analysed by gas chromatography-mass spectrometry (GC-MS). Compound annotation was performed by comparing the mass spectrum of each chromatographic peak in the sample with a mass spectral library and standards, where available. Results: A total of 53 compounds were detected in E-cigs, 44 in HTPs and 41 in TTPs by HS-SPME. Solvent extraction revealed 43 compounds in E-cigs, 35 in HTPs and 22 in TTPs. Only 7 compounds were common to E-cigs, HTPs, and TTPs. Overall, the chemical classes included alcohols, aldehydes, ketones, esters, pyridines and others. The composition of HTPs and TTPs was similar (20 compounds in common), particularly in the classes of ketones, alcohols, terpenoids, and pyridines. In contrast, E-cigs contain a larger number of compounds than HTPs and TTPs, including several alcohols, esters, pyranones, and lactones. The volatile composition of HTPs and TPPs showed less variation between different brands, whereas E-cig brands showed greater variability in their composition. Conclusions: HTPs have a volatile chemical composition similar to that of TTPs in their original form, so their health effects will depend on the impact of the different types of combustion. E-cigs show a distinct chemical profile across all brands, with chemical classes that are potentially relevant for toxicological studies.

description: No abstracts are to be cited without prior reference to the author.Spirolides were discovered by Hu et al. 1995 in scallops from Canada. They represent eight macrocyclic polyethers with molecular weights ranging from 691 to 711. In 2000, Cembella et al. identified the dinoflagellate Alexandrium ostenfeldii as producer of these toxins. In European waters the presence of spirolide producing organisms was proven by investigation of a cultured isolate of A. ostenfeldii from Limfjord, Denmark. To obtain further information about the occurrence of spirolides in Europe some 200 phytoplankton samples were taken from surface water during a reasearch cruise in May 2000. Samples were analysed on board of the research vessel for several algal toxins by LC-MS. Spirolides were detected in 75% of the samples collected in a large area (~45.000 km2) in the North Atlantic and along the Scottish east coast. The contamination differed concerning both the amounts and the relative abundance of the spirolide toxins. Conventional extraction of the phytoplankton samples resulted in low spirolide concentrations. Furthermore, similar structures (differing often only in one double bond) and the lack of commercially available external standards rendered especially quantification of spirolide toxins. Therefore, additional clean-up and concentration steps using size-exclusion chromatography were introduced enabling identification of individual spirolides by application of LC-MS-MS.

description: Background: Cancer is a complex disease characterized by several alterations that confer on the cells, the capacity to proliferate uncontrollably and to resist cellular death. Multiresistance to conventional chemotherapy drugs is often the cause of treatment failure; thus, the search for natural products or their derivatives with therapeutic action is essential. Chiral derivatives of xanthones (CDXs) have shown potential inhibitory activity against the growth of some human tumor cell lines and the influence of the stereochemistry [1,2]. Objective: This study aimed to screen a library of previously synthesized CDXs in a panel of cancer cell lines to identify the most promising compounds for further study as possible chemotherapy drugs, as well as to analyze their effect on several parameters of cancer cells and verify whether the compounds under study were substrates of P-glycoprotein (P-gp), one of the main mechanisms of resistance in cancer therapy. Methods: In this study, cell viability assays were performed on three tumor cell lines: MCF-7, NCI-H460, and A375-C5 using a library of previously synthesized CDXs. CDXs’ effect was analysed based on several parameters of cancer cells, like extracellular levels of glucose and lactate, the mechanism of cell death, and it was also verified whether these compounds were substrates of P-gp. Results: The cytotoxic activity of forty-six CDXs was evaluated, and an enantiomeric pair was considered as lead compounds and selected for other studies since they presented GI50 values lower than 15 μM for all cell lines. The selectivity index higher than 1 against cancer cells was found for both enantiomers, indicating that these compounds are considerably more specific to cancer cells, which is desirable. No significant changes were identified in the metabolic parameters analysed and it was not possible to determine whether the compounds are P-gp substrates. The main mechanism of death triggered by these compounds was apoptosis. Conclusions: These results show that some CDXs present promising antitumor activity, but other mechanisms besides metabolism, should be triggered by these compounds. Evidence of enantioselectivity was found being the D enantiomer more cytotoxic, compared to L.

description: No abstracts are to be cited without prior reference to the author.Many metrics exist for quantifying the status and change in status of fish communities over time. Each of these metrics uses a single characteristic to measure change. However, the belief that a single characteristic can capture all relevant change is likely to be naïve, and such an approach may not show important changes. Thus using a number of characteristics together could give a better picture of any change, and provide a tool that could warn against deleterious changes in the fish community. Based on a series of hypotheses about how the life history characteristics of individual fish species determine their sensitivity to fishing, we develop aggregate indices and study how they respond in a number of systems. This approach is of particular use in areas where extensive survey data sets are not available, and data-demanding ecosystem models cannot be applied. In all areas, for most species, several life history characteristics are known, at least as global values. Here we use a number of species characteristics for fish sampled during surveys, weighted with annual abundance to look at both temporal and spatial evolution. Changes in fishing effort are also considered. Potential explanations for any observed changes are given both in terms of fishing impacts and environmental influences. Conclusions are made about the utility of these types of metrics as descriptive and predictive tools.
