We aimed to investigate the relationships between advanced glycation end-products, measured as skin autofluorescence, and vascular stiffness in various glycemic strata. Methods We performed a cross-sectional analysis within the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam cohort, comprising n = 3535 participants (median age 67 years, 60% women). Advanced glycation end-products were measured as skin autofluorescence with AGE-Reader (TM), vascular stiffness was measured as pulse wave velocity, augmentation index and ankle-brachial index with Vascular Explorer (TM). A subset of 1348 participants underwent an oral glucose tolerance test. Participants were sub-phenotyped into normoglycemic, prediabetes and diabetes groups. Associations between skin autofluorescence and various indices of vascular stiffness were assessed by multivariable regression analyses and were adjusted for age, sex, measures of adiposity and lifestyle, blood pressure, prevalent conditions, medication use and blood biomarkers. Results Skin autofluorescence associated with pulse wave velocity, augmentation index and ankle-brachial index, adjusted beta coefficients (95% CI) per unit skin autofluorescence increase: 0.38 (0.21; 0.55) for carotid-femoral pulse wave velocity, 0.25 (0.14; 0.37) for aortic pulse wave velocity, 1.00 (0.29; 1.70) for aortic augmentation index, 4.12 (2.24; 6.00) for brachial augmentation index and - 0.04 (- 0.05; - 0.02) for ankle-brachial index. The associations were strongest in men, younger individuals and were consistent across all glycemic strata: for carotid-femoral pulse wave velocity 0.36 (0.12; 0.60) in normoglycemic, 0.33 (- 0.01; 0.67) in prediabetes and 0.45 (0.09; 0.80) in diabetes groups; with similar estimates for aortic pulse wave velocity. Augmentation index was associated with skin autofluorescence only in normoglycemic and diabetes groups. Ankle-brachial index inversely associated with skin autofluorescence across all sex, age and glycemic strata. Conclusions Our findings indicate that advanced glycation end-products measured as skin autofluorescence might be involved in vascular stiffening independent of age and other cardiometabolic risk factors not only in individuals with diabetes but also in normoglycemic and prediabetic conditions. Skin autofluorescence might prove as a rapid and non-invasive method for assessment of macrovascular disease progression across all glycemic strata.

T1 - BMI and BMI change following incident type 2 diabetes and risk of microvascular and macrovascular complications BT - the EPIC-Potsdam study JF - Diabetologia : journal of the European Association for the Study of Diabetes (EASD) N2 - Aims/hypothesis Studies suggest decreased mortality risk among people who are overweight or obese compared with individuals with normal weight in type 2 diabetes (obesity paradox). However, the relationship between body weight or weight change and microvascular vs macrovascular complications of type 2 diabetes remains unresolved. We investigated the association between BMI and BMI change with long-term risk of microvascular and macrovascular complications in type 2 diabetes in a prospective cohort study. Methods We studied participants with incident type 2 diabetes from the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam cohort, who were free of cancer, cardiovascular disease and microvascular disease at diagnosis (n = 1083). Pre-diagnosis BMI and relative annual change between pre- and post-diagnosis BMI were evaluated in multivariable-adjusted Cox models. Results There were 85 macrovascular (myocardial infarction and stroke) and 347 microvascular events (kidney disease, neuropathy and retinopathy) over a median follow-up of 10.8 years. Median pre-diagnosis BMI was 29.9 kg/m(2) (IQR 27.4-33.2), and the median relative annual BMI change was -0.4% (IQR -2.1 to 0.9). Higher pre-diagnosis BMI was positively associated with total microvascular complications (multivariable-adjusted HR per 5 kg/m(2) [95% CI]: 1.21 [1.07, 1.36], kidney disease 1.39 [1.21, 1.60] and neuropathy 1.12 [0.96, 1.31]) but not with macrovascular complications (HR 1.05 [95% CI 0.81, 1.36]). Analyses according to BMI categories corroborated these findings. Effect modification was not evident by sex, smoking status or age groups. In analyses according to BMI change categories, BMI loss of more than 1% indicated a decreased risk of total microvascular complications (HR 0.62 [95% CI 0.47, 0.80]), kidney disease (HR 0.57 [95% CI 0.40, 0.81]) and neuropathy (HR 0.73 [95% CI 0.52, 1.03]), compared with participants with a stable BMI; no clear association was observed for macrovascular complications (HR 1.04 [95% CI 0.62, 1.74]). The associations between BMI gain compared with stable BMI and diabetes-related vascular complications were less apparent. Associations were consistent across strata of sex, age, pre-diagnosis BMI or medication but appeared to be stronger among never-smokers compared with current or former smokers. Conclusions/interpretation Among people with incident type 2 diabetes, pre-diagnosis BMI was positively associated with microvascular complications, while a reduced risk was observed with weight loss when compared with stable weight. The relationships with macrovascular disease were less clear.

However, its pollution is of great concern due to agricultural activities in the region and the extensive use of pesticides. In a long term, this practice leads to environmental pollution, especially to the aquatic system. The objective of this study was to analyze the physicochemical characteristics, metals and pesticides levels in water samples obtained before and after the planting and pesticides' application season from three sites: Uruguay River and two minor affluents, Mezomo Dam and Salso Stream. For biomonitoring, the free-living nematode Caenorhabditis elegans was used, which were exposed for 24 h. We did not find any significant alteration in physicochemical parameters. In the pre- and post-pesticides' samples we observed a residual presence of three pesticides (tebuconazole, imazethapyr, and clomazone) and metals which levels were above the recommended (As, Hg, Fe, and Mn). Exposure to both pre- and post-pesticides' samples impaired C. elegans reproduction and post-pesticides samples reduced worms' survival rate and lifespan. PCA analysis indicated that the presence of metals and pesticides are important variables that impacted C. elegans biological endpoints. Our data demonstrates that Uruguay River and two affluents are contaminated independent whether before or after pesticides' application season. In addition, it reinforces the usefulness of biological indicators, since simple physicochemical analyses are not sufficient to attest water quality and ecological safety.

Moreover, there is a current trend towards sustainable local solutions for aquaculture and saline agriculture. In this context, halophytes are becoming increasingly important for research and the food industry. As Salicornia europaea is a highly salt-tolerant obligate halophyte that can be used as a food crop, indoor cultivation with saline water is of particular interest. Therefore, finding a sustainable alternative to the use of seawater in non-coastal regions is crucial. Our goal was to determine whether natural brines, which are widely distributed and often available in inland areas, provide an alternative water source for the cultivation of saline organisms. This case study investigated the potential use of natural brines for the production of S. europaea. In the control group, which reflects the optimal growth conditions, fresh weight was increased, but there was no significant difference between the treatment groups comparing natural brines with artificial sea water. A similar pattern was observed for carotenoids and chlorophylls. Individual components showed significant differences. However, within treatments, there were mostly no changes. In summary, we showed that the influence of the different chloride concentrations was higher than the salt composition. Moreover, nutrient-enriched natural brine was demonstrated to be a suitable alternative for cultivation of S. europaea in terms of yield and nutritional quality. Thus, the present study provides the first evidence for the future potential of natural brine waters for the further development of aquaculture systems and saline agriculture in inland regions.

EDCs are often components of synthetically manufactured products. Materials made of plastics, building materials, electronic items, textiles or cosmetic products can be particularly contaminated (Ain et al., 2021). One group of EDCs that has gained increased interest in recent years is phthalates. They are used as plasticizers in plastic materials to which people are daily exposed to. Phthalate plasticizers exert their harmful effects among others via activation of the estrogen receptor α (ERα), the estrogen receptor β (ERβ) and via inhibition of the androgen receptor (AR). Some phthalates have already been classified by the EU as Cancerogenic-, Mutagenic-, Reprotoxic- (CMR) substances and their use in industry has been restricted. After oral ingestion, phthalates are metabolized and are finally excreted with the urine. Numerous toxicological studies exist on phthalates, but mainly with the parent substances, not with their primary and secondary metabolites. In the course of the restriction of phthalates by the EU, the phthalate-free plasticizer di-isononylcyclohexane-1,2-dicarboxylate (DINCH®), was introduced to the market. So far, almost no toxicologically relevant properties have been identified for DINCH®. However, the effects of DINCH® have only been studied in animal experiments and, as with phthalates, almost exclusively with the parent substance. However, toxic effects of a particular compound may be induced by its metabolites and not by the parent compound itself. Therefore, potential endocrine effects of 15 phthalates, 19 phthalate metabolites, DINCH®, and five of its metabolites were investigated using reporter gene assays on the ERα, ERβ, and the AR. In addition, studies of the influence of some selected plasticizers on peroxisome proliferator-activated receptor α (PPARα) and peroxisome proliferator-activated receptor γ (PPARγ) activity were performed. Furthermore, a H295R steroidogenesis assay was performed to determine the influence of DINCH® and its metabolites on estradiol or testosterone synthesis. Analysis of the experiments shows that the phthalates either stimulated or inhibited ERα and ERβ activity and inhibited AR activity, whereas the phthalate metabolites did not affect the activity of these human hormone receptors. In contrast, metabolites of di-(2-ethylhexyl) phthalate (DEHP) stimulated transactivation of the human PPARα and PPARγ in analogous reporter gene assays, although DEHP itself did not activate these nuclear receptors. Therefore, primary and secondary phthalate metabolites appear to exert different effects at the molecular level compared to the parent compounds. Similarly, the results showed that the phthalate-free plasticizer DINCH® itself did not affect the activity of ERα, ERβ, AR, PPARα and PPARγ, while the DINCH® metabolites were shown to activate all these receptors. In the case of AR, DINCH® metabolites mainly enhanced AR activity stimulated by dihydrotestosterone (DHT). In the H295R steroidogenesis assay, neither DINCH® nor any of its metabolites affected estradiol or testosterone synthesis. Primary and secondary metabolites of DINCH® thus exert different effects at the molecular level than DINCH® itself. However, all these in vitro effects of DINCH® metabolites were observed only at high concentrations, which were about three orders of magnitude higher than the reported DINCH® metabolite concentrations in human urine. Therefore, the in vitro data does not support the assumption that DINCH® or any of the metabolites studied could have significant endocrine effects in vivo at relevant exposure levels in humans. Following the demonstration of direct and indirect endocrine effects of the studied plasticizers, a new effect-based in vitro 3D screening tool for toxicity assays of non-genotoxic carcinogens was developed using estrogen receptor-negative (ER-) MCF10-A cells and estrogen receptor-positive (ER+) MCF-12A cells. This arose from the background that breast cancer is the most common cancer occurring in women and estrogenic substances, such as phthalates, can probably influence the disease. The human mammary epithelial cell lines MCF-10A and MCF-12A form well-differentiated acini-like structures when cultured in three-dimensional Matrigel culture for a period of 20 days. The model should make it possible to detect substance effects on cell differentiation and growth, on mammary cell acini, and to differentiate between estrogenic and non-estrogenic effects at the same time. In the present study, both cell lines were tested for their suitability as an effect-based in vitro assay system for non-genotoxic carcinogens. An Automated Acinus Detection And Morphological Evaluation (ADAME) software solution has been developed for automatic acquisition of acinus images and determination of morphological parameters such as acinus size, lumen size, and acinus roundness. Several test substances were tested for their ability to affect acinus formation and cellular differentiation. Human epithelial growth factor (EGF) stimulated acinus growth for both cell lines, while all trans retinoic acid (RA) inhibited acinar growth. The potent estrogen 17β-estradiol had no effect on acinus formation of MCF-10A cells but resulted in larger MCF-12A acini. Thus, the parallel use of both cell lines together with the developed high content screening and evaluation tool allows the rapid identification of the estrogenic and cancerogenic properties of a given test compound. The morphogenesis of the acini was only slightly affected by the test substances. On the one hand, this suggests a robust test system, on the other hand, it probably cannot detect low-potent estrogenic compounds such as phthalates or DINCH®. The advantage of the robustness of the system, however, may be that vast numbers of "positive" results with questionable biological relevance could be avoided, such as those observed in sensitive reporter gene assays. N2 - Der Mensch ist häufig einer Vielzahl von endokrin wirksamen Chemikalien (EDCs) ausgesetzt, die schädliche Auswirkungen haben können, z. B. Störungen von Wachstum, Entwicklung und Fortpflanzung sowie Krebs (UBA, 2016). Eine Gruppe von EDCs, die in den letzten Jahren vermehrt an Interesse gewonnen hat, sind die Phthalate. Diese werden als Weichmacher in Kunststoffen verwendet. Einige Phthalate wurden bereits von der EU als Kanzerogene-, Mutagene-, Reproduktionstoxische- (CMR) Stoffe klassifiziert und ihre Verwendung in der Industrie beschränkt. Nach der oralen Aufnahme werden Phthalate metabolisiert und schließlich mit dem Urin ausgeschieden. Für die Phthalate existieren zwar zahlreiche toxikologische Studien, allerdings vorwiegend mit den Ausgangssubstanzen, nicht mit ihren primären und sekundären Metaboliten. Im Zuge der Beschränkung der Phthalate durch die EU wurde der phthalatfreie Weichmacher Diisononylcyclohexan-1,2-dicarboxylat (DINCH®), auf den Markt gebracht. DINCH® werden bisher kaum toxikologisch relevante Eigenschaften zugeordnet. Bislang wurden die Auswirkungen von DINCH® jedoch lediglich in Tierexperimenten untersucht und fast ausschließlich mit der Stamm-Substanz. Aus diesem Grund wurden potentiell endokrine Effekte von 15 Phthalaten, 19 Phthalat-Metaboliten, DINCH® und fünf seiner Metabolite unter Verwendung von Reportergen-Assays auf den ERα, ERβ und den AR untersucht. Zusätzlich wurden Untersuchungen des Einflusses einiger ausgewählter Substanzen auf die Aktivität des Peroxisom-Proliferator-aktivierten Rezeptor α (PPARα) und des Peroxisom-Proliferator-aktivierten Rezeptor γ (PPARγ) durchgeführt. Weiterhin wurde ein H295R-Steroidogenese-Assay durchgeführt, um den Einfluss von DINCH® und seinen Metaboliten auf die Estradiol- oder Testosteronsynthese zu bestimmen. Die Auswertung der Experimente zeigt, dass die Phthalate entweder die ERα- und ERβ-Aktivität stimulierten oder hemmten und die AR-Aktivität hemmten, während die Phthalatmetaboliten keinen Einfluss auf die Aktivität dieser menschlichen Hormonrezeptoren hatten. Im Gegensatz dazu stimulierten die Metaboliten von Di-(2-ethylhexyl) phthalat (DEHP) die Transaktivierung des humanen PPARα und PPARγ in analogen Reportergen-Assays, obwohl DEHP selbst diese Kernrezeptoren nicht aktivierte. Daher scheinen primäre und sekundäre Phthalatmetaboliten im Vergleich zu den Ausgangsverbindungen unterschiedliche Wirkungen auf molekularer Ebene auszuüben. Ebenso zeigten die Ergebnisse, dass der phthaltfreie Weichmacher DINCH® selbst keinen Einfluss auf die Aktivität von ERα, ERβ, AR, PPARα und PPARγ hatte, während die DINCH®-Metaboliten nachweislich alle diese Rezeptoren aktivierten. Im Falle des AR verstärkten die DINCH®-Metaboliten vor allem die durch Dihydrotestosteron (DHT) stimulierte AR-Aktivität. Im H295R-Steroidogenese-Assay beeinflusste weder DINCH® noch einer seiner Metaboliten die Estradiol- oder Testosteronsynthese. Primäre und sekundäre Metabolite von DINCH® üben demnach auf molekularer Ebene andere Effekte aus als DINCH® selbst. Die hier gewonnenen in vitro-Daten unterstützen die Annahme nicht, dass DINCH® oder einer der untersuchten Metaboliten erhebliche endokrine Wirkungen in vivo bei relevanten Expositionsmengen beim Menschen haben könnten. Nachdem endokrine Wirkungen der untersuchten Weichmacher nachgewiesen werden konnten, wurde ein neues wirkungsbasiertes in vitro 3D-Screening-Tool für Toxizitäts-Tests nicht genotoxischer Karzinogene mit östrogenrezeptor-negativen (ER-) MCF10-A-Zellen und östrogenrezeptor-positiven (ER+) MCF-12A-Zellen entwickelt. Dies geschah aus dem Hintergrund, dass Brustkrebs die häufigste Krebsart bei Frauen ist und östrogene Stoffe wie Phthalate die Krankheit vermutlich beeinflussen können. Die humanen Brustepithelzelllinien MCF-10A und MCF-12A bilden gut differenzierte azinusartige Strukturen, wenn sie in dreidimensionaler Matrigel-Kultur über einen Zeitraum von 20 Tagen kultiviert werden. Das Modell sollte es ermöglichen Substanzeffekte auf die Zelldifferenzierung und das Zellwachstum der Brustzell-Azini zu detektieren und dabei gleichzeitig zwischen östrogenen und nicht östrogenen Effekten differenzieren. Eine Softwarelösung zur automatisierten Acinus Detection And Morphological Evaluation (ADAME) wurde zur automatischen Erfassung von Acinus-Bildern und zur Bestimmung morphologischer Parameter wie Azinus-Größe, Lumengröße und Azinus-Rundheit entwickelt. Eine Reihe von Testsubstanzen wurde auf ihre Fähigkeit getestet, die Azinusbildung und die zelluläre Differenzierung zu beeinflussen. Der humane epitheliale Wachstumsfaktor (EGF) stimulierte das Azinuswachstum für beide Zelllinien, während all-trans-Retinsäure (RA) das Azinuswachstum hemmte. Das starke Östrogen 17β-Östradiol hatte keinen Einfluss auf die Azinusbildung von MCF-10A-Azini, führte aber zu größeren MCF-12A-Azini. Die parallele Verwendung beider Zelllinien zusammen mit dem hierbei entwickelten High-Content-Screening- und Evaluierungstool ermöglicht somit die schnelle Identifizierung der östrogenen oder kanzerogenen Eigenschaften einer gegebenen Testverbindung. Die Morphogenese der Azini wurde durch die Testsubstanzen nur geringfügig beeinflusst. Dies spricht einerseits für ein robustes Testsystem, andererseits kann es wahrscheinlich keine niedrigpotenten östrogenen Verbindungen wie Phthalate oder DINCH® erkennen. Der Vorteil der Robustheit des Systems kann jedoch darin liegen, dass eine große Zahl "positiver" Ergebnisse mit fragwürdiger biologischer Relevanz vermieden werden könnte, wie sie bei empfindlichen Reportergen-Assays zu beobachten sind.

Growing evidence indicates the crucial role of Se and Se-containing selenoproteins in the brain and brain function. As for the other essential trace elements, dietary Se needs to reach effective concentrations in the central nervous system (CNS) to exert its functions. To do so, Se-species have to cross the blood-brain barrier (BBB) and/or blood-cerebrospinal fluid barrier (BCB) of the choroid plexus. The main interface between the general circulation of the body and the CNS is the BBB. Endothelial cells of brain capillaries forming the so-called tight junctions are the primary anatomic units of the BBB, mainly responsible for barrier function. The current review focuses on Se transport to the brain, primarily including selenoprotein P/low-density lipoprotein receptor-related protein 8 (LRP8, also known as apolipoprotein E receptor-2) dependent pathway, and supplementary transport routes of Se into the brain via low molecular weight Se-species. Additionally, the potential role of Se and selenoproteins in the BBB, BCB, and neurovascular unit (NVU) is discussed. Finally, the perspectives regarding investigating the role of Se and selenoproteins in the gut-brain axis are outlined.
