description: Die Stadtwerke Bochum Holding GmbH beabsichtigt auf dem Gelände Mark 51°7 in Bochum eine geothermische Anlage zu errichten, die Grubenwasser aus dem stillgelegten Kohlebergwerk Dannenbaum zum Heizen und Kühlen nutzt. Hierfür wurden im Zeitraum 2021 bis 2022 die Strecken der 4. und 8. Sohle des Grubengebäudes Dannenbaum mit je einer Bohrung bohrtechnisch und hydraulisch erschlossen. Die Schächte der Zeche Dannenbaum waren nach ihrer Stilllegung im Jahr 1958 verfüllt und die Grube geflutet worden. Als erste der zwei Bohrungen wurde die Bohrung GT2 in die 4. Sohle des Grubengebäudes bis auf 343 m abgeteuft. Im Anschluss wurde die Bohrung GT1 vom gleichen Bohrplatz aus bis 864 m in die 8. Sohle zielgenau abgeteuft. In beiden Bohrungen deuteten das plötzliche Abfallen des Wasserspiegels sowie der Verlust der Meißelbelastung in der erwarteten Bohrtiefe auf ein erfolgreiches Antreffen der nur 3 m hohen Strecken hin. Um den hydraulischen Anschluss zum Grubengebäude genauer zu untersuchen, wurden in 2023 unter Einsatz einer 300 m tief installierten Förderpumpe und unter Einbindung beider Bohrungen Pumpversuche konzipiert und erfolgreich umgesetzt. Diese demonstrierten, dass das Bergwerk im Bereich der erschlossenen Sohlen hydraulisch zugängig ist und dass die für den zukünftigen Betrieb angestrebten Betriebsraten bis zu 160 m³/h unter laminaren Strömungsverhältnissen und mit nur geringen Druckdifferenzen umgesetzt werden können. Gleichzeitig zeigten sich trotz ähnlicher Geometrie der Strecken Unterschiede in den hydraulischen Eigenschaften der Bohrungen. In unserem Vortrag werden wir über die bohrtechnische Erschließung des Bergwerks sowie die Ergebnisse der Pumpversuche im Detail berichten. Das Projekt D2Grids wird durch INTERREG Nordwesteuropa-Mittel unterstützt.

description: The aim of this study was evaluate the potential use of apple wastes, as pomaces, after industrial transformation, to extract polyphenols for biotechnological applications. Apples solid wastes from industrial transformation were used as raw material to produce extracts enriched in antioxidant polyphenols, using a green and environmental friendly solvent in a solid-liquid extraction. The reaction parameters studied were the temperature (30, 50, 70, 90ºC), extraction time (10, 20, 40, 60 minutes), solvent ratio (ethanol:water, 20:80, 40:60, 60:40, 80:20) and solid:liquid ratio (1:1, 2:1, 4:1, 8:1). Response surface methodology based on central composite design was used to assess the main impact of the different extraction factors.  The phytochemical composition was assessed by HPLC-DAD/VIS-UV system and the free radical scavenging activity was measured by cupric reducing antioxidant capacity (CUPRAC) method. Our findings are important since polyphenols have an outstanding role in health area, and wide applications in food and pharmaceutical products. The optimized extraction method used in the current study might be less expensive, simple and accurate for the recovery of polyphenols based in an environmentally-friendly extraction solvent. These findings may contribute to its industrial applications for nutraceutical products development.

description: I have fabricated a chamber which enables the application of Nanosecond Pulsed Electric Fields (nsPEFs) to living cells while monitoring their real time fluorescence with an inverted microscope. The No. I thickness (150µm nominal) coverslip glass substrate used for fabrication allows the use of high numerical aperture oil immersion objectives for imaging intracellular organelles. Electrodes are fabricated by first evaporating a chromium adhesion layer, followed by a nickel seed layer. Subsequently, an ultra-thick positive photoresist is applied and patterned to create a 30µm thick electroplating mold. The electrodes are then electrodeposited into the mold from a nickel sulfamate plating bath. These electrodes are gold plated to ensure biological inertness. The process results in 25µm thick gold-plated electrodes with near vertical side walls deposited directly onto the glass coverslip with no glue layer. The electrode gap distance is 100µm which enables electric fields of up to I00kV/cm to be applied with a solid state switched Blumlein line pulse generator used in the microscope pulsing apparatus. I have applied nsPEF's to B16-FI0 Murine Melanoma cells and have recorded real time Calcium change using the indicator Fluo-4 AM. These preliminary experiments were conducted at a physiological temperature of 37°C and suggest B16 cells recover from intracellular Calcium release within minutes. In the development of this process I have minimized fabrication costs while selecting steps to maximize ease of processing. Several innovations in processing are discussed which allow semiconductor-style fabrication involving thin film deposition, photolithography, and electrodeposition to be performed outside of a conventional cleanroom while yielding acceptable results. Once fabricated,

I conducted the first biological experiments with this chamber by studying the changes in intracellular Ca2+ in B16 melanoma cells in response to Nanosecond Pulsed Electric Fields. The main findings emerging from this work are: I) Intracellular Ca2+ increases immediately upon exposure to nsPEF as low as 30 kV/cm; 2) Larger imposed fields in the range of 30-100 kV/cm result in a larger Ca2+ increase; 3) The recovery to normal Ca2+ levels is highly temperature dependent with recovery time at the physiological temperature of 37°C averaging one minute compared to greater than 10 minutes at room temperature; 4) The role of extracellular Ca2+ influx was examined by measuring the Ca2+ increase in the absence of extracellular Ca2+. This revealed that intracellular Ca2+ release is 45% of the total Ca2+ flux; and 5) The magnitude of Ca2+ increase is dependent upon the pulse frequency.

description: We evaluate the information that can unintentionally leak into the low dimensional output of a neural network, by reconstructing an input image from a 40- or 32-element feature vector that intends to only describe abstract attributes of a facial portrait. The reconstruction uses blackbox-access to the image encoder which generates the feature vector. Other than previous work, we leverage recent knowledge about image generation and facial similarity, implementing a method that outperforms the current state-of-the-art. Our strategy uses a pretrained StyleGAN and a new loss function that compares the perceptual similarity of portraits by mapping them into the latent space of a FaceNet embedding. Additionally, we present a new technique that fuses the output of an ensemble, to deliberately generate specific aspects of the recreated image.

INTENSIFICATION IN LANGUAGE AND SPEECH
Creators: name: Abdullaeva, S.M.
Publisher: name: Zenodo

description: Following P.A. Lekant, intensification in language and speech can be understood as a number of functional-semantic operations, including emphasis (accentuation), strengthening, completeness, gradation (usually its high degree), generalization and evaluation [Lekant 2011: 58]. Intensification is associated with the expression of emotions of a native speaker, for whom it is important to strengthen the semantics of his words in a given situation. This is why U. Labov believes that the means of linguistic intensification underlie social and emotional expression in the speaker's speech [Labov 1984: 43].

Publisher: name: Universitäts- und Landesbibliothek Bonn

Subjects: subject: ddc:630

description: The agricultural sector is undergoing a profound transformation process to meet international and national regulations and laws. These are being enacted by policymakers to limit the sector's tremendous gaseous emissions in an effort to reduce anthropogenic global warming and limit the effects of climate change. In this process, the improvement of slurry management strategies, i.e. the storage and application of slurry, is of particular importance, as this sector is one of the main sources of greenhouse gas emissions such as methane (CH4) and nitrous oxide (N2O) and of the environmentally harmful gas ammonia (NH3). Therefore, this dissertation investigates and evaluates two different slurry treatment strategies based on the application of alkaline additives with the aim to reduce these emissions.
 In the first study, a new mathematical tool is presented that allows the visualization of the main buffer systems in slurry. It facilitates the characterization of the buffer system and reveals their underlying dynamics. The knowledge gained contributes to the optimization of mitigation strategies relying on pH adjustment by the application of alkaline additives. This tool was successfully verified by more than 300 titrations of slurry stored at different temperatures and for different periods. The collected data revealed that buffer systems are subject to significant fluctuations during storage, which are greatly influenced by temperature. These fluctuations are caused by dynamic formation and degradation processes that are interrelated and thus form a complex system.
 The second study of this dissertation implements and assesses the first slurry treatment strategy, which is based on the application of calcium hydroxide (Ca(OH)2) as an alkaline additive to increase the pH value of the slurry. The study results demonstrated that during a storage period of 8 weeks and a pH value of 10, the emissions of CH4 and CO2 were reduced by 99% and these of N2O by 60%, while a further increment did not cause a greater reduction. In addition, the framework conditions that must be adhered to for this strategy to be implemented successfully are outlined.
 The third study presents the second slurry treatment strategy in which calcium cyanamide (CaCN2) is utilized as a slurry additive to reduce gaseous emission during a long-term storage period of 26 weeks. It was demonstrated that CaCN2 suppressed CH4 emissions rapidly and long-lasting, resulting in a reduction potential of total greenhouse gas emissions by up to 99% over the entire storage period. Furthermore, it was shown that the application inhibited the microbial conversion of volatile fatty acids to CH4, which caused the pH to drop during storage, resulting in a reduction of NH3 emissions.

description: Abstract

The study examined teacher background training as determinants of pre-school children’s writing skills in Southwestern Nigeria. The study adopted mixed design that consisted of observation and correlational design. A self-designed instrument was used for this study. The population for the study consisted of all the pre-school children and their teachers in Southwestern Nigeria. The sample size for the study consisted of 120 pre-school teachers and 600 pre-school children. The study adopted a multi-stage sampling procedure. Three states were selected from six states in Southwestern Nigeria using simple random sampling technique through a ballot system. The instrument used was “Preschool Children Writing Skill Rubric” (PCWSR). Data for PCWSR was a administered by checking children’s’ note books. The data were analysed using Independent Sample T-test. Results indicated that teacher background training significantly influenced preschool children’s writing skills (df = 598; t = 11.476; p < 0.05). The study concluded that teachers’ training background was found to be the factor that could influence the writing skills of preschool children.

description: The metaverse, envisioned as the next digital frontier for avatar-based virtual interaction, involves high-performance models. In this dynamic environment, users' tasks frequently shift, requiring fast model personalization despite limited data. This evolution consumes extensive resources and requires vast data volumes. To address this, meta-learning emerges as an invaluable tool for metaverse users, with federated meta-learning (FML), offering even more tailored solutions owing to its adaptive capabilities. However, the metaverse is characterized by users heterogeneity with diverse data structures, varied tasks, and uneven sample sizes, potentially undermining global training outcomes due to statistical difference. Given this, an urgent need arises for smart coalition formation that accounts for these disparities. This paper introduces a dual game-theoretic framework for metaverse services involving meta-learners as workers to manage FML. A blockchain-based cooperative coalition formation game is crafted, grounded on a reputation metric, user similarity, and incentives. We also introduce a novel reputation system based on users' historical contributions and potential contributions to present tasks, leveraging correlations between past and new tasks. Finally, a Stackelberg game-based incentive mechanism is presented to attract reliable workers to participate in meta-learning, minimizing users' energy costs, increasing payoffs, boosting FML efficacy, and improving metaverse utility. Results show that our dual game framework outperforms best-effort, random, and non-uniform clustering schemes - improving training performance by up to 10%, cutting completion times by as much as 30%, enhancing metaverse utility by more than 25%, and offering up to 5% boost in training efficiency over non-blockchain systems, effectively countering misbehaving users.

description: Redox homeostasis is achieved by antioxidant systems, involving a large collection of enzymes that scavenge or degrade Reactive Oxygen Species (ROS) produced endogenously at low levels during cell growth. Besides the enzymatic protection against ROS, cells also contain small antioxidant molecules, such as glutathione (GSH). With an intracellular concentration between 1 and 10 mM, GSH is the most abundant non-protein thiol in the cell and is considered as the major redox buffer of the cell. In a previous study, we showed that only scarce amounts of intracellular GSH are required to protect yeast nuclear activities during oxidative stress. Surprisingly, such protection is sufficient for cell survival despite the strong oxidation of cytosolic proteins and the complete inhibition of protein synthesis (Hatem et al., 2014).

GSH synthesis is a two-step process involving the gamma-glutamylcysteine (g-GC) synthetase Gsh1, which produces the g-GC intermediate from glutamate and cysteine, and the glutathione synthetase Gsh2, which adds a glycine to g-GC to release the final tripeptide. Deletion of GSH2 leads to yeast cells accumulating abnormal amounts of g-GC. It has been suggested that this molecule could replace GSH during oxidative stress exposure as the viability of ∆gsh2 cells, unable to synthesize GSH, is only mildly affected in oxidative stress conditions.

Because our previous study revealed that the antioxidant protection of all cellular components and activities is not strictly required to preserve cell viability during oxidative stress, we decided to better characterize the physiological response of ∆gsh2 cells submitted to hydrogen peroxide treatments. Here we present the main results of this study and discuss the potential role of g-GC in the cellular protection against oxidative injury, compare to GSH.

description: The rare-earth nickelates possess a diverse set of collective phenomena including metal-to-insulator transitions, magnetic phase transitions, and, upon chemical reduction, superconductivity. Here, we demonstrate epitaxial stabilization of layered nickelates in the Ruddlesden-Popper form, Nd$_{n+1}$Ni$_n$O$_{3n+1}$, using molecular beam epitaxy. By optimizing the stoichiometry of the parent perovskite NdNiO$_3$, we can reproducibly synthesize the $n = 1 - 5$ member compounds. X-ray absorption spectroscopy at the O $K$ and Ni $L$ edges indicate systematic changes in both the nickel-oxygen hybridization level and nominal nickel filling from 3$d^8$ to 3$d^7$ as we move across the series from $n = 1$ to $n = \infty$. The $n = 3 - 5$ compounds exhibit weakly hysteretic metal-to-insulator transitions with transition temperatures that depress with increasing order toward NdNiO$_3$ ($n = \infty)$.

description: We have developed a process, which can protect cocoa flavanols by embedding them into lycopene, or other carotenoids. This results in an increase in their ‘survival’ in the digestive tract, and consequently in an improvement in their absorption and efficacy. Clinical studies demonstrated that our process can improve the bioavailability of these molecules and increase their efficacy so that a piece of 5-10g has the power of 100g of unmodified dark chocolate.
We used this enriched cocoa flavanol Smart Chocolate as a platform to combine other food bioactive molecules with established physiological properties. They included lycopene to protect plasma lipoproteins, lutein and zeaxanthin to support neuron tissues, and astaxanthin to boost mitochondria respiration. Results of clinical validation demonstrated their superior efficacy above unmodified dark chocolate and conventional supplementation.

In addition we combined this platform with trans-resveratrol. The main problem in clinical application of this molecule is that in isolated form its bioavailability 100 to 1,000 lower than when it is consumed with red wine. By using our technology we developed chocolate with bioavailability of t-RSV boosted to the level of red wine.

description: We analyze two sectors of TESS photometry of the nova-like cataclysmic variable star V533 Her. We detect a periodicity consistent with the binary orbital period and estimate a revised value of 3.53709(2) hr. We also detect a strong signal near a period of 3.8 h that we associate with positive superhumps. The superhump frequency varies over the TESS observations with the fractional difference between the superhump and orbital periods, $ε$, ranging between $0.055\le ε\le 0.080$. The superhump amplitude is correlated with its frequency such that the amplitude increases as $ε$ decreases. Positive superhumps result from an instability that generates an eccentric accretion disk and $ε$ is a measure of the disk precession rate in the binary rest frame. The observed correlation implies that as the disk precession rate slows, the disk eccentricity increases.

description: Table olives are recognized as a valuable source of natural phenolic antioxidants. In this study we analyzed the ability of the phenolic fraction of a Sardinian cultivar of naturally fermented table olives, “Tonda di Cagliari”, to protect Caco-2 cell monolayers against oxidative stress and membrane disruption induced by tert-butil hydroperoxide (TBH). TBH exposure resulted in an alteration of cellular redox status, with an increase of ROS and a decrease of GSH intracellular level, which led over time to a loss of the epithelial integrity, as indicated by the decrease of the transepithelial electrical resistance (TEER) value. Pretreatment of Caco-2 cells with the olives phenolic extract at non-toxic concentrations (10 – 50 µg/mL) prevented ROS generation, GSH depletion and the loss of the epithelial integrity. The protective action of the extract is likely due to the ability of its main components, hydroxytyrosol, oleuropein and verbascoside, to scavenge TBH generated radicals or intermediate of reaction metabolites. Olives phenolic compounds concentrate in the intestinal lumen, where they may contribute, together with their metabolites, to protect the intestinal mucosa against the damage caused by oxidative species.

Why systems, materials, and atoms tend to seek stability over time
Creators: name: Passolungo, Simone
Publisher: name: Zenodo
Year: 2025

description:  This formula emerges from a unified vision of the physical behavior of the universe, where every observable phenomenon is a form of restitution of an initial energy delta (delta-E). The equation does not merely describe motion, but the way in which energy is distributed across space and time to complete its cycle of return. It is not an effect, but a principle: everything that happens is a form of coherent restitution. This principle also explains why systems, materials, and atoms tend to seek stability over time if not energetically perturbed. It is the natural outcome of inevitable energy dissipation that cannot be avoided—every structure, left undisturbed, will always move toward a state where the delta-E is balanced or minimized.

description: Grape processing for the production of wine generates a wide range of residues (pomace and seeds) rich in bioactive compounds (polyphenols, etc). Their biological potential has been already valorised in ruminant nutrition, but has been little investigated in pigs. This study was conducted to analyse the effect of dietary inclusion of grape seed by-product on growth performance, immune and antioxidant function in weaned pigs. A total of 12 weaned pigs were fed with a control or 5% grape seed cakes (GS) diets for 30 days. Pigs were sacrificed after 30 days, blood and organs were collected and stored at –80°C until analyses. The results showed that dietary GS did not exert significant effect on pig performance, but generated an anti-inflammatory effect by decreasing gene expression of TNF-α, IL-6, IFN-γ and other inflammatory molecules in liver. No effect on the activity and gene expression of antioxidant enzymes and malondialdehyde was also observed in liver. The effect on inflammation was less evident in spleen, but a slight increase in antioxidant enzyme activity was noticed. In conclusion, the dietary inclusion of GS modulated differentially immune and antioxidant response in weaned pig.

description: Games have been used at the Royal Institute of Technology (Sweden) and the University of Cambridge (UK) to aid the teaching of sustainable development to diverse groups of engineering students. This paper explores how games have helped students at two institutions to reflect on issues from different perspectives. More specifically, the work addresses whether games helped to stimulate students’ learning of facts; student reflections; and student peer discussions. The games evaluated include: Building Futures; Democracy; Dilemma; Fishbanks; GaSuCo; Power Grid; and Puerto Mauricio. Methodologies used include: student surveys; deep interviews; group interviews; and essays, written assignments and tests. The main findings are that games contribute strongly to the learning of sustainability and improve critical reflection as well as facilitate interpersonal communication.

description: Green tea and cranberry are rich with phenolic compounds and they are extensively studied for their cardioprotective, anti-carcinogenic and anti-infective activities. This study analyzes their effect on gut microbiota and selected biochemical parameters in lean NMRI mice and in monosodium glutamate (MSG) – induced mouse model of obesity with insulin resistance and hyperinsulinemia.
 Results on the species richness show similarity of the groups that were fed by standard chow and the diet enriched with green tea extract, both in the normal (lean) mice and those with MSG-induced obesity. On the contrary, mice treated with cranberry extract tend to form a separate cluster of data points, showing a more pronounced difference between this group and control and green tea-treated groups. Again, the shift is present in both normal and obese group of mice. In other words, the analysis of species richness indicate a lowering of the number of taxonomic units after intake of cranberry extract; this effect was even more apparent in obese mice. On the contrary, the green tea extract did not cause a prominent change of the species richness of the mice gut microbiome.

description: While the importance of evaluating the education of sustainable development programmes has been widely recognised, very limited information is available on the topic. QUESTE - SI project was funded by the European Commission under the Lifelong Learning programme ERASMUS (2010-2012). QUESTE - SI stands for “Quality system of European Scientific and Technical Education for Sustainable Industry”. The project was coordinated by EFMD, the Management Education Network, and ENQHEEI, the European Network for Quality of Higher Engineering Education for Industry. The QUESTE - SI evaluation and accreditation focuses on the institutional unit (department) that is responsible for one or more programmes. A key point is to ensure that each graduate learns the sustainability aspects related to the concerned education domain. A fair evaluation of social responsibility and sustainability education is not limited to teaching and learning methods or curricular content – it depends on parallel efforts in all dimensions. The main objective of the paper is to present, analyse and discuss principles, implementation and results of the original assessment and accreditation system for higher engineering education. The system comprises all five roles of the university: education, research, infrastructure and management, students’ involvement and society. More than 10 European science and technical universities have been accredited in accordance to the QUESTE - SI requirements. Kaunas University of Technology was represented by the Institute of Environmental Engineering with the M.Sc. Programme “Environmental Management and Cleaner Production” and the Ph.D. Programme “Environmental Engineering and Landscape Management”. The Institute of Environmental Engineering has been awarded the highest ranking and has become a fertile basis for a larger pilot project. The paper presents principles, methodology, results of QUESTE-SI evaluation and accreditation and the experience of pilot institution.

description: Anomaly-based intrusion detection promises to detect novel or unknown attacks on industrial control systems by modeling expected system behavior and raising corresponding alarms for any deviations.As manually creating these behavioral models is tedious and error-prone, research focuses on machine learning to train them automatically, achieving detection rates upwards of 99%. However, these approaches are typically trained not only on benign traffic but also on attacks and then evaluated against the same type of attack used for training. Hence, their actual, real-world performance on unknown (not trained on) attacks remains unclear. In turn, the reported near-perfect detection rates of machine learning-based intrusion detection might create a false sense of security. To assess this situation and clarify the real potential of machine learning-based industrial intrusion detection, we develop an evaluation methodology and examine multiple approaches from literature for their performance on unknown attacks (excluded from training). Our results highlight an ineffectiveness in detecting unknown attacks, with detection rates dropping to between 3.2% and 14.7% for some types of attacks. Moving forward, we derive recommendations for further research on machine learning-based approaches to ensure clarity on their ability to detect unknown attacks.

description: The aim of the present study was to evaluate the influence of a diet containing 5% grape pomace (GP) on polyphenols absorption and their antioxidant antiradicalic activity (DPPH test) on weaning piglets. 20 crossbred TOPIG starter piglets were assigned to one of the 2 treatments: control (10 piglets- normal diet for weaned pig-C) and diet with GP (10 piglets -diet -D) for 36 days. After 15 days and at the end of the experimental period, blood samples were collected from the two groups. All piglets were slaughtered and the organs, liver, spleen, duodenum, colon, kidney, Longissimus dorsi muscle, mesenteric lymph nodes, heart and brain were collected. The total polyphenols (TP) content and the antioxidant activity of the feed diet and diet components as well as of the blood and organs were determined by using Folin Ciocalteu and DPPH test respectively. GP increased the TP content in feed as well as its antioxidant activity. Expressed as % of control, TP were found to be higher in plasma, duodenum, colon, kidneys and heart than in the control. The highest antioxidant activity was found in liver, kidneys and heart.

description: Charge-order states of broken symmetry, such as charge density wave (CDW), are able to induce exceptional physical properties, however, the precise understanding of the underlying physics is still elusive. Here, we combine fluctuational electrodynamics and density functional theory to reveal an unconventional thermophotonic effect in CDW-bearing TiSe$_2$, referred to as thermophotonic-CDW ($tp$-CDW). The interplay of plasmon polariton and CDW electron excitations give rise to an anomalous negative temperature dependency in thermal photons transport, offering an intuitive fingerprint for a transformation of the electron order. Additionally, the demonstrated nontrivial features of $tp$-CDW transition hold promise for a controllable manipulation of heat flow, which could be extensively utilized in various fields such as thermal science and electron dynamics, as well as in next-generation energy devices.

description: Objectives: Recent studies showed that Spanish guava leaves are a source of phenolic compounds that have been related to the prevention and treatment of Diabetes Mellitus[1],[2]. Thus, the aim of this work was to evaluate the effects of an extract from guava leaves, on vascular dysfunction in obese mice.
Methodology: an extract from guava leaves was characterized by HPLC-DAD-ESI-TOF-MS, and it was tested on obese mice fed a high fat-rich diet to evaluate the vascular dysfunction.
Results: Firstly, the analysis of the extract by HPLC-DAD-ESI-TOF-MS revealed that flavonols represented a 49.2 % from the sum of phenolic in the leaves, followed by gallic/ ellagic acid derivatives (29.3 %) and flavan-3-ols (21.5 %). Moreover, major compounds were the isomers reynoutrin, guajaverin and avicularin. Secondly, the administration of the extract (5 mg/kg) to obese mice did not alter weight evolution, but improved the glucose tolerance test. Also, it caused a significant amelioration in all the metabolic markers evaluated in plasma. Moreover, the endothelial dysfunction was reversed in the extract-treated group.
Conclusions: the beneficial effects in obese mice of guava leaf extract, related to its phenolic composition, were associated to an improvement in the altered vascular functions that occur in obesity.
