description: The effects of three medicinal plants used in ethnopharmacology, corn silk (Maydis stigma), parsley (Petroselinum crispum) and bearberry leaves (Uva ursi folium) on antioxidant capacity pretreated mice blood and liver were determined. The first group of ten animals drank corn silk, second parsley and third bearberry leaf extract. The fourth group was the control when animals drank water. Extracts and water were administrated ad libitum. Antioxidant status of blood and liver was investigated by determining superoxide dismutase, catalase, guiacole peroxidase, glutathione peroxidase activities and reduced glutathione quantity. Quantities of generated hydroxyl and DPPH radicals, lipid peroxidation LP and total antioxidant power, FRAP, were determined at the end of experiment. On the basis of the overall presented results corn silk and bearberry extracts confirmed the therapeutic values known in ethnomedicine and could be proposed for further investigations as a new therapeutic approach in prevention and treatment of blood and liver diseases in modern medicine.

description: The flavonoid fraction of bergamot juice (BJe) has demonstrated radical-scavenging and anti-inflammatory activities. The aim of this study was to investigate the effects of BJe on the modulation of the ileum inflammation caused by intestinal ischemia/reperfusion (I/R) injury. This was induced in mice by clamping the superior mesenteric artery and the celiac trunk for 30 min, followed by release of the clamp, allowing reperfusion for 1 h. After 1 h of reperfusion, animals were killed for histological examination of the ileum tissue, the expression of  proinflammatory cytokines and adhesion molecules; for biochemical assays such as myeloperoxidase activity (MPO) and malondialdehyde (MDA) levels. Moreover, by Western blot analysis, we also investigated the expression of nuclear factor NF-κB, IκB-α, inducible nitric oxide synthase (iNOS) and the expression of antioxidant such as MnSOD. The results obtained from histological and molecular examinations showed that BJe was able to reduce histological damage, cytokines production, adhesion molecules expression, neutrophil infiltration and oxidative stress. In addition, NF-κB and MAP kinases pathways were also modulated by BJe treatment. In conclusion, in this study we demonstrated that BJe could represent a possible treatment against secondary events of intestinal I/R injury.

description: Parkinson's disease (PD) is a neurodegenerative disorder characterized by the degeneration of dopaminergic nigrostriatal neurons and loss of substantia nigra. Fumaric acid esters (FAEs) display immunomodulatory and anti-inflammatory properties. Recent studies showed that treatment with FAEs significantly reduces leukocyte infiltration in experimental autoimmune encephalomyelitis and colitis and also activates the Nrf2 antioxidant response pathway.

The aim of the present study was to evaluate the potential effects of dimethyl fumarate (DMF) in a mouse model of PD. Mice received four injections of the dopaminergic neurotoxin MPTP, starting 24 h after the first administration of MPTP, animals received DMF (10-30-100 mg/kg ip) daily for 7 days. On the 8th days, brains were processed for future analysis.

Treatments with DMF significantly increased the expression of tyrosine hydroxylase (TH) and dopamine transporter (DAT) and reduced α-synuclein; moreover, DMF treatment significantly reduced pro-inflammatory markers such as NFκB, COX-2 and nitrosative stress and exerts protective effects enhancing recovery of motor function. The results of the present study clearly showed that DMF exerts its neuroprotective effects possibly by reducing the neuroinflammation and activating the Nrf2 antioxidant response pathway. DMF may constitute a promising therapeutic target for the treatment of neurodegenerative diseases such as PD.

description: The aim of this study was to evaluate the effectiveness of isolation of antioxidants from bergenia (Bergenia rassifolia L.) (BCr), buckwheat flowers (Fogopyrum esculentum) (BF) and European goldenrod leaves (Solidago virgaulea) (RL) using pressurised liquid extraction (PSE) with increasing polarity solvents (hexane, acetone, ethanol:water(80:20) and water), and supercritical fluid extraction with pure carbon dioxide (SFE–CO2) and with added co–solvent ethanol.

The yields of BCr, BF and RL extracts obtained by SFE–CO2 varied from 0.37 (BCr) to 2.4 (RL) % (w/w dry matter) , whereas adding 10 % of high polarity ethanol increased extract yields approx. 2 times. In case of PLE the yields of analysed plants were remarkably higher, indicating that solvent polarity played the most important role. The antioxidant capacity was evaluated by Oxygen Radical Absorbance Capacity (ORAC) assay applying it to the extracts and straight to the solid ground before and after extractions (QUENCER method). The extracts were analyzed by UPLC–UV–QTOF–MS/MS. The main compounds were identified and quantified.
 In general, the results showed that bergenia, buckwheat flowers and rod leaves contain various polyphenolic compounds, possessing beneficial health effects; therefore these plants may be considered as a promissing sources of functional nutraceutical ingredients.

description: High incidence of melanoma in the individuals with red hair is due to the syntesis of pheomelanin pigments in the human tissue and its phototoxic properties.

Evaluation of melanoma risk in different individuals, can be accomplished by analyzing ESR spectras of their hairs, but at the same time it’s needed to find an effective antioxidant, capable to minimize damage of pheumelanin.

We have shown, that ascorbic acid is an effective antioxidant for neutralization of pheumelanin free radicals. We have defined presumable optimal concentration of ascorbic acid, which neutralizes free radicals in the human hair– 10mmole.

It is also important, that ascorbic acid has an influence on the free radicals of both pheumelanin, as well as eumelanin and optimal dose concentration for both is the same.

Chemical mechanism of influence of ascorbic acid on free radicals of eumelanin and pheumelanin is also shown.

According to changes of ESR signal we have considered, that ascorbic acid doublet is overlapped with spectras of red and black hair.

Finally, it can be said, that presumable optimal dose of ascorbic acid, to be used in the creams for skin protection, as well as for prevention of different skin disorders has been defined in vitro.

description: Antimony selenide (Sb2Se3) is at the forefront of an emerging class of sustainable photovoltaic materials. Despite notable developments over the past decade, the light-to-electricity conversion efficiency of Sb2Se3 has reached a plateau of ~10%. Is this an intrinsic limitation of the material or is there scope to rival the success of metal halide perovskite solar cells? Here we assess the trap-limited conversion efficiency of Sb2Se3. First-principles defect analysis of the hole and electron capture rates for point defects demonstrates the critical role of vacancies as active recombination centres. We predict an upper limit of 25% efficiency in Sb2Se3 grown under optimal equilibrium conditions where the concentrations of charged vacancies are minimised. We further reveal how the detrimental effect of Se vacancies can be reduced by extrinsic oxygen passivation, highlighting a pathway to achieve high-performance metal selenide solar cells close to the thermodynamic limit.

description: The classical causal relations between a set of variables, some observed and some latent, can induce both equality constraints (typically conditional independences) as well as inequality constraints (Instrumental and Bell inequalities being prototypical examples) on their compatible distribution over the observed variables. Enumerating a causal structure's implied inequality constraints is generally far more difficult than enumerating its equalities. Furthermore, only inequality constraints ever admit violation by quantum correlations. For both those reasons, it is important to classify causal scenarios into those which impose inequality constraints versus those which do not. Here we develop methods for detecting such scenarios by appealing to d-separation, e-separation, and incompatible supports. Many (perhaps all?) scenarios with exclusively equality constraints can be detected via a condition articulated by Henson, Lal and Pusey (HLP). Considering all scenarios with up to 4 observed variables, which number in the thousands, we are able to resolve all but three causal scenarios, providing evidence that the HLP condition is, in fact, exhaustive.

OXIDATIVE STRESS  LIVER: MODULATORS OF OXIDATIVE STRESS IN ALCOHOLIC LIVER INJURY AND REGENERATION

Publisher: name: Journal of International Society of Antioxidants in  Nutrition & Health
Year: 2016

description: The pro-fibrogenic gene, Wnt/β-catenin signaling pathway is well established to play a major role in hepatic fibrogenesis. PI proposes that hepatic fibrogenic process is negligible in normal liver because nucleoredoxin (NXN), a key liver antioxidant, interacts with Dvl that prevents frizzled (Fzd) to form Fzd: Dvl complex leading to preferential phosphorylation and consequent degradation of β-catenin via the proteasomal pathway. However, chronic alcohol-induced reactive oxygen species oxidize NXN and dissociate Dvl from NXN: Dvl complex resulting in inhibiting GSK3β and consequent stabilization and translocation of β-catenin into the nucleus, where it activates hepatic fibrogenesis. Resveratrol is a natural polyphenol found in grapes that has strong phytoestrogenic and antioxidant properties.

Pr. Lakshman proposes to discuss how alcohol abuse affects these complex signaling interactions in hepatic fibrogenesis, and the protective role of resveratrol in blocking these fibrogenic actions of chronic alcohol exposure.

description: The homeostasis of epithelial tissue relies on a balance between the self-renewal of stem cell populations, cellular differentiation, and loss. Although this balance needs to be tightly regulated to avoid pathologies, such as tumor growth, the regulatory mechanisms, both cell-intrinsic and collective, which ensure tissue steady-state are still poorly understood. Here, we develop a computational model that incorporates basic assumptions of stem cell renewal into distinct populations and mechanical interactions between cells. We find that the model generates unexpected dynamic features: stem cells repel each other in the bulk tissue and are thus found rather isolated, as in a number of in vivo contexts. By mapping the system onto a gas of passive Brownian particles with effective repulsive interactions, that arise from the generated flows of differentiated cells, we show that we can quantitatively describe such stem cell distribution in tissues. The interaction potential between a pair of stem cells decays exponentially with a characteristic length that spans several cell sizes, corresponding to the volume of cells generated per stem cell division. Our findings may help understanding the dynamics of normal and cancerous epithelial tissues.

description: We compute the time evolution of the non-equilibrium entropy in the homogeneous isotropization dynamics of the 1RCBH model, which has a critical point in its conformal phase diagram defined at finite temperature and R-charge density. We also evaluate the time evolution of the pressure anisotropy and the scalar condensate of the medium. We disclose a new feature (not present in the Bjorken flow dynamics analyzed in previous works), which is observed for all the analyzed initial data: the formation of a periodic sequence of several close plateaus in the form of a stairway for the entropy density near thermodynamic equilibrium. We find that the period of plateau formation in the stairway is half the period of oscillations of the slowest quasinormal mode of the system, which is therefore strongly tied to the late time dissipative dynamics of the system associated to the irreversibility of entropy production. For the particular case of the purely thermal SYM plasma at zero density and vanishing scalar condensate, we find that the period of the stairway is half the period of oscillations of the slowest quasinormal mode associated to the late time equilibration of the pressure anisotropy of the fluid, while at finite chemical potential the slowest quasinormal mode of the system is associated to the late time equilibration of the scalar condensate.

description: We investigate the quantum transport of the heat and the charge through a quantum dot coupled to fermionic contacts under the influence of time modulation of temperatures. We derive, within the nonequilibrium Keldysh Green's function formalism, generic formulas for the charge and heat currents by extending the concept of gravitational field introduced by Luttinger to the dynamically driven system and by identifying the correct form of dynamical contact energy. In linear response regime our formalism is validated from satisfying the Onsager reciprocity relations and demonstrates its utility to reveal nontrivial dynamical effects of the Coulomb interaction on charge and energy relaxations.

Search for long-lived, massive particles in events with displaced vertices and multiple jets in pp collisions at √s = 13 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Springer Berlin Heidelberg
Year: 2024

description: A search for long-lived particles decaying into hadrons is presented. The analysis uses 139 fb−1 of pp collision data collected at √ s = 13 TeV by the ATLAS detector at the LHC using events that contain multiple energetic jets and a displaced vertex. The search employs dedicated reconstruction techniques that significantly increase the sensitivity to longlived particles decaying in the ATLAS inner detector. Background estimates for Standard Model processes and instrumental effects are extracted from data. The observed event yields are compatible with those expected from background processes. The results are used to set limits at 95% confidence level on model-independent cross sections for processes beyond the Standard Model, and on scenarios with pair-production of supersymmetric particles with long-lived electroweakinos that decay via a small R-parity-violating coupling. The pair-production of electroweakinos with masses below 1.5 TeV is excluded for mean proper lifetimes in the range from 0.03 ns to 1 ns. When produced in the decay of m(g˜) = 2.4 TeV gluinos, electroweakinos with m(χ˜ 0 1 ) = 1.5 TeV are excluded with lifetimes in the range of 0.02 ns to 4 ns.
Helicobacter pylori and the Development of Gastric Cancer

description: My research was inspired by a close friend who has Crohn’s Disease. This autoimmune disorder causes chronic bowel inflammation resulting in irritable bowel disease, diarrhea, and malnutrition. Although there is no cure, current treatment uses antibiotics, corticosteroids, and immunosuppressants to alleviate most symptoms. Originally assigned to write a review paper for my microbiology and immunology course, I wanted to research the latest literature in potential groundbreaking treatments for Crohn’s Disease that may lead to developing a cure. Ultimately, I found very little save for the multitude of studies on current treatments. One of the most intriguing studies I found using Goucher’s library database Biological Abstracts related the development of Crohn’s Disease to infection with a particular gram negative stomach bug called Helicobacter pylori. However, despite this correlation to an infectious bacteria, there was no explanation of how or why H. pylori was associated with this autoimmune disorder. Having run into a dead end, I began researching the ways in which H. pylori induces gastric cancer specifically because this virulent method of inducing cancer comprises five percent of the world’s cancer burden. I was amazed at how much research was devoted to this field of study and I was able to access the majority of my research articles for free using Bio One, Biological Abstracts, and PubMed. The few articles I could not immediately access, I was able to receive in a few days through Goucher’s interlibrary loan service. Although I was ultimately unable to achieve my original goal of researching advancements into the treatment of Crohn’s Disease, I explored the potential mechanisms of eradication of gastric cancer and H. pylori, which may reduce the incidence of Crohn’s Disease. Overall, my research method using Goucher’s databases taught me to be patient and to explore alternate mechanisms when the first doesn’t work

description: We study 't Hooft anomalies of global symmetries in 1+1d lattice Hamiltonian systems. We consider anomalies in internal and lattice translation symmetries. We derive a microscopic formula for the "anomaly cocycle" using topological defects implementing twisted boundary conditions. The anomaly takes value in the cohomology group $H^3(G,U(1)) \times H^2(G,U(1))$. The first factor captures the anomaly in the internal symmetry group $G$, and the second factor corresponds to a generalized Lieb-Schultz-Mattis anomaly involving $G$ and lattice translation. We present a systematic procedure to gauge internal symmetries (that may not act on-site) on the lattice. We show that the anomaly cocycle is the obstruction to gauging the internal symmetry while preserving the lattice translation symmetry. As an application, we construct anomaly-free chiral lattice gauge theories. We demonstrate a one-to-one correspondence between (locality-preserving) symmetry operators and topological defects, which is essential for the results we prove. We also discuss the generalization to fermionic theories. Finally, we construct non-invertible lattice translation symmetries by gauging internal symmetries with a Lieb-Schultz-Mattis anomaly.

description: In 1827, Tsar Nicholas I instituted the Cantonist Decree, which led to the impressment of thousands of Jewish children into the Russian army. While officially, Jewish religious freedom was to be protected, the unofficial goal of the Cantonist system was to assimilate Russia’s Jewish minority. By encouraging the new institution of the Chapper or Kidnapper, the new legislation was successful in undermining the religious authority of the Kahal. Furthermore, many Cantonist children were coerced to convert to Russian Orthodoxy through abusive means. However, although the Cantonist system succeeded in converting over one third of Jewish recruits1 and led to the dissolution of the Kahal, the non-standard treatment of the Jewish minority contributed to a feeling of otherness that culminated in the strengthening of Jewish identity in spite of institutionalized anti-Semitism.

description: Megapodagrion megalopus (SELYS, 1862) Figures 11-12 Material. 7♂, 1 ♀, Base Camp. Remarks. All specimens were taken in the forest, far from water, flying close to the ground or sitting on sticks or stemlets of low growing plants. The larval habitat is unknown. but might not be lotic. Megapodagrion Selys sensu stricto is monoty pic. Those species included in Allopodagrion Forster, currentlv considered a subgenus of the former, differ in many important features from M. megalopus . Therefore I think that full generic rank for Allopodagrion, as originally assigned to by Forster (1910), is clearly justified. The strongest argument for doing so is given by penis morphology: The penis of Megapodagrion is lestine (Fig. 11-12), while that of Allopodagrion is typically megapodagrionine (Figs. 13-14) with two conspicuos cornua as have, for example, Dimeragrion Calvert, Heteragrion Selys, Oxystigma Williamson, Philogenia Selys and Sciotropis Racenis. Petiolation of wings ceases far distad from cux in Megapodagrion, but very close to, or even proximally of cux in Allopodagrion. Megapodgrion has two supplementary sectors between IR2 and R3 and two more between R3 and IR3 whiIe Ailopodagrion has only one in each space. The fore wings are shorter than the hind wings in Megapodagrion but equal or longer in Allopodagrion. Adult Megapodagrion are mottled with brown, the two apical abdominal segments are in thtl male densely covered with white pruinescence Adult Allopodagrion are black with blue patches on the mesepisterna, which might be covered by blue pruinescence, tip of abdomen has no pruinescence. The larval habitat of Megapodagrion is unknown, but adults are found in lowland rain forest away from running water flying close to the ground. All species of Allopodagrion are instead breeding in small mountain creeks in partly open or closed forest and do not abandon the water courses. It seems, therefore, that besides of the long legs, Allopodagrion does not share more characters with Megapodagrion than with Philogenia or with any other of the compared genera

description: A standard approach to solve ordinary differential equations, when they describe dynamical systems, is to adopt a Runge-Kutta or related scheme. Such schemes, however, are not applicable to the large class of equations which do not constitute dynamical systems. In several physical systems, we encounter integro-differential equations with memory terms where the time derivative of a state variable at a given time depends on all past states of the system. Secondly, there are equations whose solutions do not have well-defined Taylor series expansion. The Maxey-Riley-Gatignol equation, which describes the dynamics of an inertial particle in nonuniform and unsteady flow, displays both challenges. We use it as a test bed to address the questions we raise, but our method may be applied to all equations of this class. We show that the Maxey-Riley-Gatignol equation can be embedded into an extended Markovian system which is constructed by introducing a new dynamical co-evolving state variable that encodes memory of past states. We develop a Runge-Kutta algorithm for the resultant Markovian system. The form of the kernels involved in deriving the Runge-Kutta scheme necessitates the use of an expansion in powers of $t^{1/2}$. Our approach naturally inherits the benefits of standard time-integrators, namely a constant memory storage cost, a linear growth of operational effort with simulation time, and the ability to restart a simulation with the final state as the new initial condition.

description: We present the first detailed chemical-abundance analysis of stars from the dwarf-galaxy stellar stream Wukong/LMS-1 covering a wide metallicity range ($-3.5 < \rm[Fe/H] \lesssim -1.3$). We find abundance patterns that are effectively indistinguishable from the bulk of Indus and Jhelum, a pair of smaller stellar streams proposed to be dynamically associated with Wukong/LMS-1. We confirmed a carbon-enhanced metal-poor star ($\rm[C/Fe] > +0.7$ and $\rm[Fe/H] \sim -2.9$) in Wukong/LMS-1 with strong enhancements in Sr, Y, and Zr, which is peculiar given its solar-level [Ba/Fe]. Wukong/LMS-1 stars have high abundances of $α$ elements up to $\rm[Fe/H] \gtrsim -2$, which is expected for relatively massive dwarfs. Towards the high-metallicity end, Wukong/LMS-1 becomes $α$-poor, revealing that it probably experienced fairly standard chemical evolution. We identified a pair of N- and Na-rich stars in Wukong/LMS-1, reminiscent of multiple populations in globular clusters. This indicates that this dwarf galaxy contained at least one globular cluster that was completely disrupted in addition to two intact ones previously known to be associated with Wukong/LMS-1, which is possibly connected to similar evidence found in Indus. From these $\geq$3 globular clusters, we estimate the total mass of Wukong/LMS-1 to be ${\approx}10^{10} M_\odot$, representing ${\sim}1$% of the present-day Milky Way. Finally, the [Eu/Mg] ratio in Wukong/LMS-1 continuously increases with metallicity, making this the first example of a dwarf galaxy where the production of $r$-process elements is clearly dominated by delayed sources, presumably neutron-star mergers.

description: Lestes falcifer Sjostedt, 1918 Material (4♂). 2 ♂, Siapa 2; 2 ♂, Base Camp Remarks. All specimens were caught in the forest, away from water. At Siapa 2 L. falcifer was flying together with Gynacantha gracilis (Bur· meister) in a hollow among vines and bushes. The presence of these species, incl. oviposition of the latter, indicate that the hollow will be filled with water during rain season. Perissolestes sp. Remarks. One male was observed at Unturan. It was hanging from a twig in a dark corner of the creek, but could not be secured.

description: Objective: To simultaneously deblur and supersample prostate specific membrane antigen (PSMA) positron emission tomography (PET) images using neural blind deconvolution. Approach: Blind deconvolution is a method of estimating the hypothetical "deblurred" image along with the blur kernel (related to the point spread function) simultaneously. Traditional \textit{maximum a posteriori} blind deconvolution methods require stringent assumptions and suffer from convergence to a trivial solution. A method of modelling the deblurred image and kernel with independent neural networks, called "neural blind deconvolution" had demonstrated success for deblurring 2D natural images in 2020. In this work, we adapt neural blind deconvolution for PVE correction of PSMA PET images with simultaneous supersampling. We compare this methodology with several interpolation methods, using blind image quality metrics, and test the model's ability to predict kernels by re-running the model after applying artificial "pseudokernels" to deblurred images. The methodology was tested on a retrospective set of 30 prostate patients as well as phantom images containing spherical lesions of various volumes. Results: Neural blind deconvolution led to improvements in image quality over other interpolation methods in terms of blind image quality metrics, recovery coefficients, and visual assessment. Predicted kernels were similar between patients, and the model accurately predicted several artificially-applied pseudokernels. Localization of activity in phantom spheres was improved after deblurring, allowing small lesions to be more accurately defined. Significance: The intrinsically low spatial resolution of PSMA PET leads to PVEs which negatively impact uptake quantification in small regions. The proposed method can be used to mitigate this issue, and can be straightforwardly adapted for other imaging modalities.

description: In response to the global shift towards renewable energy resources, the production of green hydrogen through electrolysis is emerging as a promising solution. Modular electrolysis plants, designed for flexibility and scalability, offer a dynamic response to the increasing demand for hydrogen while accommodating the fluctuations inherent in renewable energy sources. However, optimizing their operation is challenging, especially when a large number of electrolysis modules needs to be coordinated, each with potentially different characteristics.
 To address these challenges, this paper presents a decentralized scheduling model to optimize the operation of modular electrolysis plants using the Alternating Direction Method of Multipliers. The model aims to balance hydrogen production with fluctuating demand, to minimize the marginal Levelized Cost of Hydrogen (mLCOH), and to ensure adaptability to operational disturbances. A case study validates the accuracy of the model in calculating mLCOH values under nominal load conditions and demonstrates its responsiveness to dynamic changes, such as electrolyzer module malfunctions and scale-up scenarios.
