Utilization of Ultraviolet C Light-Emitting Diodes for the Deactivation of SARS-CoV-2 in Human Breath

Ultraviolet light has a long track record when it comes to use for deactivating harmful microorganisms. With recent developments in LED technology in terms of generating electromagnetic waves from this specific spectral range, new applications have emerged. In this study, the possibility of constructing an effective miniature UV barrier for deactivating the SARS-CoV-2 virus in both exhaled and inhaled air is investigated. Our findings demonstrate that utilizing commonly available UVC diodes operating at the wavelength of 275 nm makes it possible to attain an adequate level of deactivation that fulfills the standards specified for commercial devices.

Transition Metal-Doped SnO2 As Versatile Battery Electrode Material

Tin oxide-based materials have been intensively investigated as alternative anodes for lithium-ion batteries due to their high specific capacity, environmental friendliness, non-toxicity, and ease of handling. However, the initial formation of Li2O upon lithiation is essentially irreversible, which has a severe effect on the first cycle Coulombic efficiency and the reversibly achievable capacity in general.[1]It has been shown that the incorporation of transition metal dopants can address this issue, as it enables the reversible formation and reformation of Li2O.[2] The choice of the dopant, however, plays a critical role for the long-term cycling stability, rate capability, and eventual energy density of the resulting lithium-ion cells.[3] While there have been intensive studies published already on the effect of different dopants for Li-ion battery applications, targeting an optimized combination for achieving enhanced cycling performance[3] and an in-depth understanding of the reaction mechanism,[4,5] the investigation as Na-ion battery active material has not been reported so far. In fact, our results show that the reaction mechanism is fundamentally different, while the incorporation of transition metal dopants is still favorable for the eventual charge storage via sodium cations. The resulting insights into the de-/sodiation mechanism are anticipated to enable the development of further enhanced electrode active materials for sodium-ion batteries and, thus, support the recent success of this alternative battery technology.

Lower-Body Resistance Training Reduces Interleukin-1β and Transforming Growth Factor-β1 Levels and Fatigue and Increases Physical Performance in Breast Cancer Survivors.

Martins, FM, Santagnello, SB, de Oliveira Junior, GN, de Sousa, JdFR, Michelin, MA, Nomelini, RS, Murta, EFC, and Orsatti, FL. Lower-body resistance training reduces interleukin-1β and transforming growth factor-β1 levels and fatigue and increases physical performance in breast cancer survivors. J Strength Cond Res 37(2): 439-451, 2023-This article ascertains whether resistance training (RT) improves inflammatory markers, fatigue (sensations and fatigability), and physical performance in breast cancer survivors (BCS) and investigates whether the changes in the inflammatory markers, fatigue, and physical performance are associated with each other. Volunteers were randomly divided into 2 groups: control group (n = 11) and RT group (n = 11). Resistance training (3 sets of 8-12 repetitions with 80% 1 repetition maximum (1RM) on 4 exercises-leg extension, leg curl, 45° leg press, and calf raise) was performed 3 times a week for 12 weeks. Self-reported fatigue (SRF), fatigability (critical torque [CT] and W prime [W']), muscle strength, and circulating inflammatory markers were assessed using the Brief Fatigue Inventory, iDXA, 1RM test, protocol of 60 maximal voluntary isometric contractions, and enzyme-linked immunosorbent assay, respectively. Resistance training reduced interleukin (IL)-1β, transforming growth factor (TGF)-β1, and SRF score and increased muscle strength, 6-minute walk test (6MWT), CT, and W'. In the RT group, the changes in SRF were positively associated with the changes in IL-1β. The changes in muscle strength were associated with the changes in CT and W', and the changes in the 6MWT were associated with the changes in CT, W', muscle strength, and SRF. Resistance training improved fatigue and physical performance and reduced IL-1β, and TGF-β1 in BCS. Although improvement in fatigability seems to be dependent on the increase in muscle strength, improvement in the sensation of fatigue seems to be dependent on the reduction in IL-1β after RT. Increase in physical performance seems to be dependent on improvement in muscle strength and fatigue.

Modeling Municipal Heritage Management

The resources medium-sized municipalities allocate in the process of both creating and maintaining instruments for heritage management have increased in the last decades. There are first and foremost legal reasons for this, as European national laws translate societal concerns on the preservation and commodification of the past. Sustainable solutions may be achieved through the understanding of heritage assets, and their use in the support of responsible, data-driven choices. This paper analyses a case of local tangible heritage administration in Oliveira de Azeméis, Portugal.

The party, organized by the Brotherhood of Our Lady of Conception, included a Eucharistic celebration, a monumental procession, and other profane amusements, including bullfights and fireworks. The study of this 17th century celebration focuses on the account of António de Oliveira de Cadornega is cross-checked with brotherhood documentation and with other historiography

444 pedras da réplica amazônica da “Saint Edward’s Crown” - Project 444 Stones: Arte - Ciência - História - Reflexão Política

Project by authorship and idealization of the paraense doctor Wirley Otávio Oliveira de Barros, which involves art, science, history and political reflection, developed in the city of Belém, capital of the State of Pará, in the middle of the Amazon region, registered in a notary through a Notarial Act. This grandiose work was developed with scientific support Museum of Geosciences of the Amazon (MUGEO) of the Institute of Geosciences (IG) of the Federal University of Pará (UFPA) through Prof. Dr. Marcondes Lima da Costa, with a PhD in Mineralogy and Geochemistry from Universität Erlangen-Nürnberg (Friedrich-Alexander), in Germany (1982) and with a post-doctorate in mineralogy-geochemistry from IG-USP (2001); chemist Dr. Suyanne Flávia Rodrigues, with a doctorate in Mineralogy and Geochemistry from the Graduate Program in Geology and Geochemistry (PPGG) at IG / UFPA and MsC. geologist Gisele Tavares Marques, also from PPGG. This project, which will soon be presented to the public, was duly informed to Her Majesty, Queen Elizabeth Alexandra Mary Windsor (Elizabeth II), of the United Kingdom of Great Britain and Northern Ireland, in addition to Head of Commonwealth Realms and Defender of Faith, as it presents as a prominent item the replica work of “Saint Edward's Crown” or “St. Stephen’s Crown ”, as mentioned in the Royal letter received on February 3, 2016, signed by Miss Jennie Vine (Deputy to the Senior Correspondence Officer for Buckingham Palace), who on this occasion conveys the monarch's personal message. This is the official coronation crown of British monarchs, consisting of 444 stones of distinct mineral gems, which inspired the title attributed to the project. Therefore, it is a replica of a symbol of POWER, whose heraldic meaning of CRUZ DE MALTA and FLOR-DE-LIS guide the conduct and political profile of the ruler. In this regard, the author also addresses a message to the "men of power", made through a personal text of his own.

Analysis of Physiological and Kinematic Demands of Wheelchair Basketball Games-A Review.

Seron, BB, Oliveira de Carvalho, EM, and Greguol, M. Analysis of physiological and kinematic demands of wheelchair basketball games-A review. J Strength Cond Res 33(5): 1453-1462, 2019-In wheelchair basketball (WB), knowledge of the specificities of the game is essential for efficient planning of training strategies for high performance. This study aimed to review the literature concerning studies that have investigated physiological and kinematic measures during WB games. The literature search took place in 4 electronic databases: Scopus, MEDLINE-PubMed, SPORTDiscus, and CINAHL. The inclusion criteria for this review were as follows: (a) articles that evaluated the behavior of physiological and kinematic variables during WB games; (b) athletes aged at least 18 years; and (c) participants with a minimum of 1 year in the modality practice. The selected studies (n = 16) were divided into 2 groups: physiological analysis (n = 11) and kinematic analysis (n = 5). In analyzing the studies, it was observed that the WB game is very demanding in relation to cardiovascular requirements (∼65% of the time is spent in zones of high heart rate [HR] intensity and 70% of V[Combining Dot Above]O2peak). Edwards and Stagno methods seem to be adequate for the control of internal loads imposed on WB players, and moderate correlations were found between rating of perceived exertion measures and HR-based methods. Considering the methodological limitations, kinematic analysis in WB games is rather inconsistent (distance traveled between 2.6 and 5 km; average speed between 1.8 and 2.0 m·s; maximum speed = 4 m·s). Despite the gaps observed in this context, the execution of rotational movements seems to have great relevance for WB. We can conclude that different methods have been adequate for the internal load control in WB games. However, the results of the external demands are not enough to determine a profile nor to serve as parameters for the training prescription for athletes of the modality.

CaP Coating and Low-Level Laser Therapy to Stimulate Early Bone Formation and Improve Fixation of Rough Threaded Implants.

This study aimed to compare in vivo osteogenesis on rough threaded dental implants with and without calcium phosphate (CaP) coating deposition, alone or in association with low-level laser therapy (LLLT) by gallium aluminum arsenide. Four groups were studied: G1: implant; G2: implant + CaP coating; G3: implant + LLLT; and G4: implant + CaP coating + LLLT. LLLT was applied for 7 days at the surgical site before and after placing the implant. Topographic characterization was performed before surgery using scanning electron microscopy and energy dispersion spectrophotometry. Bone-implant contact (BIC) was measured after 1, 2, and 6 weeks and reverse torque after 6 weeks. In short periods, G2, G3, and G4 showed significantly greater BIC than G1 (P < 0.05), but no difference in BIC was observed at 6 weeks. However, the values for the removal torque test at 6 weeks were higher in G2 and G4 (P < 0.05). Both CaP coating alone and using LLLT induce cellular stimulation and improve BIC in short-term healing, resulting in higher implant fixation, and should be considered in clinical practice due to their low cost and high effectiveness.

A empresa de relações públicas norte-americana contratada por Salazar (1951-1962) – A estreia da ditadura no modelo assimétrico bidirecional no período pós-António Ferro

Uma década antes de ser publicado o primeiro manual de relações públicas em Portugal, uma tradução da obra de Sam Black (1962), António de Oliveira de Salazar já tinha uma pasta com vasta correspondência pessoal com uma empresa de public relations de Nova Iorque. Chamava-se George Peabody and Associates e desenvolveu um intenso e sofisticado trabalho a nível turístico e político durante 11 anos (1951-62). Com recurso a uma pesquisa aos arquivos da Torre do Tombo e do Departamento de Justiça norte-americano, assim como ao estudo epistolográfico e prosopográfico das principais figuras do antigo regime, tentaremos demonstrar as estratégias, as táticas e os principais protagonistas desta empresa que serviu o Estado Novo e o ditador do regime. Como principal conclusão, este artigo revela como, ainda durante os anos 50 e sem António Ferro, o próprio Governo ditatorial protagonizou uma instintiva viragem comunicacional para o modelo assimétrico bidirecional (Grunig &amp; Hunt, 1984).

Abstract 4754: An ancestral link between tumor immune microenvironment and tamoxifen resistance in breast cancer

Abstract Maternal exposures to endocrine disrupting chemicals (EDCs) are known to increase daughter's breast cancer risk in humans and animal models. We have found that these exposures also pre-program mammary tumors to exhibit increased resistance to antiestrogen therapy (Hilakivi-Clarke et al. JNCI 109, 2016). Consistent with the idea that in utero EDC exposures alter later disease susceptibility by epigenetic means, we discovered that adult treatment of in utero EDC exposed rats with valproic acid (VA, non-specific HDAC inhibitor) and hydralazine (H, non-specific DNMT inhibitor) prevented tamoxifen (TAM) resistance. In contrast, in the control offspring VA+H promoted TAM resistance. Here we investigated if maternal exposure to synthetic ethinyl estradiol (EE2) alters tumor immune environment in the offspring, and if treatment with VA+H reverses the changes. Pregnant Sprague Dawley rats received 0 or 0.1 ppm EE2 during gestation days 10-20. Estrogen receptor positive (ER+) mammary tumors in the offspring were induced with 7,12-dimethylbenz[a]anthracene, and when a tumor reached 13 mm in diameter, core needle biopsies were obtained. Thereafter, offspring were treated with 15 mg/kg TAM in diet, with or without 1.2 g/kg VA and 5 mg/kg H via drinking water. Antigen processing and activating proteins CD74 and HLA-DRB5 were significantly elevated in pre-treatment tumor biopsies from in utero EE2 exposed rats. Ingenuity pathway analysis of iTraq protein data from the biopsies indicated that T cell receptor and IL15 were upstream regulators of most of the signaling changes between EE2 and control offspring. Further, non-treated mammary tumors of EE2 offspring exhibited higher mRNA levels of PD-L1, PD-1, Foxp3 and Tgfβ1 than tumors in the control offspring. TAM treatment further upregulated Foxp3 and Tgfβ1 as well as CD8a and PD-1 in the EE2 offspring. However, VA+H reversed all these changes in TAM treated in utero EE2 exposed animals. In the control offspring, a combination of TAM and VA+H increased tumor PD-1, PD-L1, Foxp3 and TGFβ1 levels, compared with non-treated tumors. Since elevated levels of Foxp3 and TGFβ1 are indicative of immunosuppression, and PD-1 and its ligand PD-L1 induce effector T cell exhaustion, our data suggest that in utero EE2 exposure promotes an immunosuppressive tumor microenvironment that allows cancer cells to evade elimination by cytotoxic T lymphocytes, especially during TAM therapy. Our findings also indicate that adding HDAC + DNMT inhibitors to the treatment regimen prevents these changes, and thus possibly explains the ability of the combination treatment to prevent antiestrogen resistance in the in utero EE2 exposed rats. Future studies will determine if the combination therapy benefits ER+ breast cancer patients exhibiting high PD-1/PD-L1 expression in pre-treatment tumors, and/or if these patients should receive checkpoint inhibitors with endocrine therapy.

Barium, zinc and strontium yellows in late 19th\u2013early 20th century oil paintings

This work focuses on the study of the 19th century yellow chromate pigments based on barium (BaCrO4), zinc (4ZnCrO4·K2O·3H2O) and strontium (SrCrO4). These pigments, which are reported to shift in hue and darken, have been found in 19th century artworks. A better understanding of their historic manufacture will contribute to the visual/chemical interpretation of change in these colours. Research was carried out on the Winsor & Newton (W&N) 19th century archive database providing a unique insight into their manufacturing processes. One hundred and three production records were found, 69% for barium, 25% for zinc and 6% for strontium chromates, mainly under the names Lemon, Citron and Strontian Yellow, respectively. Analysis of the records shows that each pigment is characterised by only one synthetic pathway. The low number of records found for the production of strontium chromate suggests W&N was not selling this pigment formulation on a large scale. Furthermore, contrary to what the authors have discovered for W&N chrome yellow pigments, extenders were not added to these pigment formulations, most probably due to their lower tinting strength (TS). The latter was calculated in comparison to pure chrome yellow (PbCrO4, 100% TS) resulting in 92% for barium, 65% for zinc potassium and 78% for strontium chromate pigments. This indicates that W&N was probably using extenders primarily to adjust pigment properties and not necessarily as a means to reduce their costs. Pigment reconstructions following the main methods of synthesis were characterised by complementary analytical techniques: Fibre optic reflectance spectroscopy, X-ray diffraction, micro-Raman and micro-Fourier transform infrared spectroscopies. These pigments can be clearly distinguished on the basis of their infrared CrO42− asymmetric stretching fingerprint profile (between 1000 and 700 cm−1) and of their Raman CrO42− stretching bands (850–950 cm−1). This enabled their identification in historic paint samples: a tube of late 19th century W&N Lemon Yellow oil paint and micro-samples from paintings by three Portuguese painters, António Silva Porto (1850–1893), João Marques de Oliveira (1853–1927) and Amadeo de Souza-Cardoso (1887–1918). The good correlation found between the reconstructions and historic samples validates their use as reference materials for future photochemical studies.

NUTRITION GAMES AND INVENTIVENESS OF PRACTITIONERS/CHILDREN

In this article we aim to make visible the practitioners/children performing arts” in a practical/experience of the daily life of the Body, Color and Flavor workshop at the Leblon Art Center of Rio de Janeiro Municipal Department of Education. The purpose of this workshop is to discourage thought/performed curricula, as well as the networks of knowledge, actions, values and beliefs in food, nutrition and health of practitioners/children in the third grade of elementary education. In this methodological path, we are guided by the thoughts of Paulo Freire, Certeau, Nilda Alves, Carlo Ginzburg, Ines Barbosa de Oliveira and Boaventura de Sousa Santos. To cheat the rules and to invent other ways of playing educational games are the schemes of children who do not recognize themselves in prescriptive and normative educational strategies.By subverting and re-signifying official artifacts, practitioners/children produced thought/performed curricula in everyday school settings. By making these doings/knowledge visible,we hope that we can instigate the exercise of the ecology of knowledge in the elaboration of these instruments and in the educational practices inside/outside schools.

Elastic Bands as a Component of Periodized Resistance Training

Joy, JM, Lowery, RP, Oliveira de Souza, E, and Wilson, JM. Elastic bands as a component of periodized resistance training. J Strength Cond Res 30(8): 2100-2106, 2016-Variable resistance training (VRT) has recently become a component of strength and conditioning programs. Prior research has demonstrated increases in power and/or strength using low loads of variable resistance. However, no study has examined using high loads of variable resistance as a part of a periodized training protocol to examine VRT within the context of a periodized training program and to examine a greater load of variable resistance than has been examined in prior research. Fourteen National Collegiate Athletic Association division II male basketball players were recruited for this study. Athletes were divided equally into either a variable resistance or control group. The variable resistance group added 30% of their 1 repetition maximum (1RM) as band tension to their prescribed weight 1 session per week. Rate of power development (RPD), peak power, strength, body composition, and vertical jump height were measured pretreatment and posttreatment. No baseline differences were observed between groups for any measurement of strength, power, or body composition. A significant group by time interaction was observed for RPD, in which RPD was greater in VRT posttraining than in the control group. Significant time effects were observed for all other variables including squat 1RM, bench press 1RM, deadlift 1RM, clean 3RM, vertical jump, and lean mass. Although there were no significant group ×-time interactions, the VRT group's percent changes and effect sizes indicate a larger treatment effect in the squat and bench press 1RM values and the vertical jump performed on the force plate and vertec. These results suggest that when using variable resistance as a component of a periodized training program, power and strength can be enhanced. Therefore, athletes who add variable resistance to 1 training session per week may enhance their athletic performance.

Environmental effects on the gills and blood of Oreochromis niloticus exposed to rivers of Bahia, Brazil

Through the integration of chemical, biochemical and morphological analyses, this study investigated the effects of multiple pollutants on environmental biomarkers, such as gill histopathological changes and hematological and biochemical parameters, in Oreochromis niloticus exposed to four sites in the Jacuipe and Subaé rivers over seven days. Sediment analyses identified Sapelba as the most contaminated site, followed by Oliveira de Campinhos, Santo Amaro and Jacuípe. Water analyses revealed aluminum, iron and manganese at all sites. Aluminum and other metal were also detected in the gills of fishes. Fish exposed to the Sapelba site exhibited significant necrosis formation, as well as higher hematological parameters and trend to increase of cortisol levels. However, filament epithelium proliferation was higher at the Oliveira de Campinhos and Santo Amaro sites, at which the lowest levels of the hematological variables were observed. Multivariate analysis grouped some gill histopathological changes together, such as epithelial detachment with edema and lamellar epithelial proliferation with the lamellar fusion of adjacent filaments, revealing relationships among them. Positive associations were identified between sediment contamination and necrosis and cortisol, while water contamination was related with filament epithelium proliferation, aneurism, lamellar fusion and several hematological parameters. Furthermore, relationships between blood parameters and gill histopathological changes demonstrated a joint physiological response that may have resulted from environmental variables such as dissolved oxygen. The results exhibited the direct influence of xenobiotics on these biomarkers but also highlighted the need to consider the complexity of environmental factors to optimize the adoption of these environmental predictive tools.

Luiz Bandeira Bridge: Assessment of a Historical Reinforced Concrete (RC) Bridge

The Luiz Bandeira Bridge is located along the Portuguese national road EN333-3, breaching the valley of the Vouga River, just northeast of the small village Sejães, in the district of Oliveira de Frades. It is considered to be the oldest concrete bridge in use in Portugal, and one of the oldest in Europe. Since this bridge is at risk of disappearing due to a construction of a dam, the Department of Civil Engineering of the University of Minho decided to launch a comprehensive study of Luiz Bandeira Bridge, in an attempt to preserve the memory of the past cataloguing the heritage for future reference. These studies include historical, geometric, and damage surveys; the physical and chemical characterization of existing structural materials; the assessment of the reinforcement detailing; and dynamic characterization by determining the main frequencies and vibration modes and safety level. This work presents a comprehensive overview of the most important results of these studies.
