Published: November 2021

With the continuous development of the Internet of things (IoTs), data security and privacy protection in the IoTs are becoming increasingly important. Aiming at the hugeness, redundancy, and heterogeneity of data in the IoTs, this paper proposes a ranked searchable encryption scheme based on an access tree. First, this solution introduces parameters such as the word position and word span into the calculation of the relevance score of keywords to build a more accurate document index. Secondly, this solution builds a semantic relationship graph based on mutual information to expand the query semantics, effectively improving the accuracy and recall rate during retrieval. Thirdly, the solution uses an access tree control structure to control user authority and realizes fine‐grained access management to data by data owners in the IoTs. Finally, the safety analysis of this scheme and the efficiency comparison with other existing schemes are given.

Published: October 2021

The incidence rate of cerebrovascular diseases is increasing year by year, but the accuracy of clinical diagnosis is not high enough to cause disease. Many patients cannot effectively diagnose and treat the disease at the early stage. CT perfusion imaging (CTP) and CT angiography (CTA) were used to diagnose cerebrovascular diseases. In this paper, 26 cases of patients with acute cerebrovascular disease in our hospital from June to August 2020 were selected as the research objects. According to the diagnosis method voluntarily chosen by patients, 6 cases were only detected by CT perfusion imaging, 8 cases were only detected by CT angiography, and the remaining 12 cases were diagnosed by CT perfusion imaging and CT angiography. Then, according to the diagnosis results of the CT image of the patients with cerebrovascular disease, these samples were followed up after 3 months, 6 months, and 9 months, and more accurate diagnosis results were obtained. The study showed that, after 3 months of CT detection, the sensitivity of patients with CTP detection was 67%, that of patients with CTA detection was 72%, and that of patients with combined detection was 83%. After 6 months of CT detection, the sensitivity of patients with CTP detection was 75%, that of patients with CTA detection was 79%, and that of patients with combined detection was 93%. After 9 months of CT detection, the sensitivity of patients with CTP detection was 86%, that of patients with CTA detection was 89%, and that of patients with combined detection was 99%. Therefore, the use of CTA combined with CTP joint detection of acute cerebrovascular disease imaging technology can effectively improve the diagnostic accuracy of patients.

Published: November 2021

In this study, polypyrrole-modified red mud (PRM) was prepared for the efficient removal of anionic dyes (methyl orange and Congo red) from aqueous solutions. The phytotoxicity (bean sprouts) of the dye solution before and after dye removal was investigated. Adsorption kinetics confirmed that the adsorption of methyl orange (MO) and Congo red (CR) on PRM was controlled by chemical reactions between the functional groups of polypyrrole and dyes. From Langmuir isotherm fitting, we found the theoretical adsorption capacities of MO and CR on PRM were 194.1 and 314.9 mg/g, respectively. The adsorption progress of MO and CR on PRM was found to be spontaneous and endothermic. The column studies demonstrated that, under dynamic flow, the PRM can efficiently remove MO and CR from aqueous solution, with adsorption capacities of 31.08 and 55.04 mg/g, respectively. In the toxicity test, the phytotoxicity of the column effluents (after dye removal) was significantly lowered compared to the initial dye influents. After the removal of MO and CR, the average root length of bean sprouts was increased from 3.30 cm to 5.18 cm and from 3.01 cm to 7.00 cm, respectively. These findings highlighted the efficient removal of dyes by PRM from aqueous solution, demonstrating the possible application of PRM for the removal of dye from dye-contaminated wastewaters.

Published: October 2021

This study aimed at screening rhizobial isolates of chickpea and evaluating their symbiotic nitrogen fixation efficiency and tolerance to abiotic stresses. A total of 107 (100%) isolates were collected of which 52 (48.6%) were confirmed as chickpea rhizobia using preliminary tests. Among 52 (48.6%) isolates, 46 (88.5%) have induced nodulation on chickpea under greenhouse and were screened under in vitro conditions and 6 (11.5%) of them were discarded due to fail to nodulate. The greenhouse data showed the highest nodule number (68.67 plant−1), nodule dry weight (0.17 g plant−1), and shoot dry weight (0.81 g plant−1) were scored by plants inoculated with isolates WUCR 17, WUCR 1, and WUCR 66, respectively. Among authenticated isolates, 73.9%, 21.7%, and 4.3% were highly effective, effective, and lowly effective, respectively. The physiological test showed 15% of isolates tolerated 13% salt concentration and 10.9% of isolates grew at pH 4–10 range. All isolates grew at 20–35°C and 13% grew at maximum temperature (50°C). The isolates showed better resistance to the tested antibiotics at low concentration (2.5 μg/ml) but the majorities were sensitive at high concentration (10 μg/ml). Among the isolates, 13% tolerated all tested heavy metals but 48% were sensitive to mercury. Regarding the carbohydrate utilization test, 52.2% catabolized all the tested 11 carbon sources but 6.5% of them utilized only 63.6% carbon sources. Amino acid utilization showed isolates (85%) utilized D-alanine except WUCR (14, 25, 31, 34, 39, 59, and 76) and 76% of the isolates utilized arginine and phenylalanine and 74% utilized leucine as a nitrogen source. Of the isolates, 43.5% of them utilized both D-alanine and arginine as a nitrogen source. In almost all tests conducted, isolates WUCR 1 and 5 performed top and were recommended as potential candidates for microbial inoculants.

Published: November 2021

The plasma-activated water (PAW), as a new environmentally friendly nonthermal processing technology, has attracted wide attention for its applications in agriculture, food, and biomedical fields. This paper used the needle array-plate dielectric barrier discharge (needle array-plate DBD) device to activate deionized water and prepare PAW simply and efficiently. It was found that the concentration of reactive oxygen and nitrogen species (RONS) generated in the process of needle array-plate DBD was large and varied. Especially in the wavelength range of 600–770 nm, the spectral intensity is stronger. And, the ionic wind is more likely to interact with the deionized water. The changes in PAW parameters and UV/Vis spectra with treatment time were measured under different voltages and needle-dielectric plate distances. Results show that increasing discharge voltage or decreasing needle-dielectric plate distance increases the concentration of RONS, ionic wind speed, water evaporation, and conductivity of the PAW and decreases pH. UV/Vis spectra results show that prolonged treatment time results in increased total absorbance and concentrations of H2O2 and

and that a new absorption peak appears at 210 nm in the UV/Vis spectra. When the wavelength is larger than 210 nm, a redshifted new peak and color enhancement are observed. The seeds of Astragalus adsurgens Pall were treated by discharge plasma, PAW, and the combination of plasma and PAW. It was found that high voltage and long-time activated PAW could significantly increase the ROS level of seeds and seedlings after germination for 3 days, resulting in oxidative stress damage. The survival rate of seeds was lower than that under the half lethal dose. This paper provides a feasible device design for treating activated water in large quantities with high efficiency, which is important for the application of PAW and mutation breeding of A. adsurgens Pall.
Evaluating the Dynamic Response of the Bridge‐Vehicle System considering Random Road Roughness Based on the Moment Method
Authors: Feng Fan , Huang Fanglin , Wen Weibin , Liu Zhe , Liu Xiang
Published: November 2021

The bridge‐vehicle interaction (BVI) system vibration is caused by the vehicles passing through the bridge. The road roughness has a great impact on the system vibration. In this regard, poor road roughness is known to affect the comfort of the vehicle crossing the bridge and aggravate the fatigue damage of the bridge. Road roughness is usually regarded as a random process in numerical calculation. To fully consider the influence of road roughness randomness on the response of the BVI system, a random BVI model was established. Thereafter, the random process of road roughness was expressed by Karhunen–Loeve expansion (KLE), after which the moment method was used to calculate the maximum probability value of the BVI system response. The proposed method has higher accuracy and efficiency than the Monte Carlo simulation (MCS) calculation method. Subsequently, the influences of vehicle speed, roughness grade, and bridge span on the impact factor (IMF) were analyzed. The results show that the road roughness grade has a greater impact on the bridge IMF than the bridge span and vehicle speed.

Authors: Jafari Fatemeh , Tabarrai Malihe , Abbassian Alireza , Jafari Farhad , Ayati Mohammad Hossein
Published: November 2021

Background. Premenstrual disorders involve physical, behavioral, and mood variations that affect women of childbearing age and interfere with family relationships, household responsibilities, professional duties, and social activities. Objectives. Considering the side effects of conventional medications, their use is not recommended except in severe cases of premenstrual disorders. Nowadays, there is a tendency to use traditional and complementary medicine that offers various treatments. The purpose of the current study was to investigate the impacts of garlic as a herbal medicine on the severity of premenstrual symptoms. Methods. This study was a double-blind, randomized, controlled trial. After identification of participants with moderate-to-severe PMS through the premenstrual symptoms screening tools questionnaire (PSST), they were randomly assigned to placebo (n = 64) or garlic (n = 65) groups. Each participant received one tablet daily for three consecutive cycles and logged the severity of their symptoms in the PSST questionnaire during the intervention period. Results. There was no significant difference between the two groups in the baseline level of premenstrual symptoms before the intervention. After treatment with garlic for three consecutive cycles, the total score of the severity of premenstrual symptoms significantly (P<0.001) reduced from 34.09 ± 7.31 to 11.21 ± 7.17. In the placebo group, this score changed from 33.35 ± 7.96 to 24.28 ± 7.22. The difference between mean changes in the two groups was 13.78, with a 95% Confidence Interval (CI) of 11.23–16.33. No serious side effects were observed in either group. Conclusion. Our findings highlight the potential effect of garlic in reducing the severity of premenstrual symptoms; therefore, the use of garlic can be considered as an alternative therapy in the prevention and treatment of premenstrual disorders.

Published: November 2021

Objective: We aimed to investigate costly punishment in patients with Huntington’s disease (HD). Background: HD is an autosomal dominant neurodegenerative disease with motor, cognitive, and psychiatric symptoms. As neuropsychiatric abnormalities often precede motor symptoms, we wanted to assess whether costly punishment is part of the neuropsychological profile of patients with HD. Methods: A total of 40 non-demented subjects were prospectively enrolled in this study with a between-subject design comparing manifest HD patients (n = 18) to healthy controls (HC; n = 22). All participants performed 8 rounds of a costly punishment task, in which money was shared unevenly in 5 rounds or in a fair manner in the remaining 3 rounds. Participants then had to decide whether they wanted to punish the trustee. Furthermore, all participants underwent neuropsychological background tasks. Results: HD patients performed worse in the neuropsychological background tests compared to HC (all p values <0.05). Moreover, HD patients punished more often in fair (Wald χ2 = 5.03, p = 0.025) but not in unfair rounds (Wald χ2 = 1.63, p = 0.202). Conclusions: Our results demonstrate increased costly punishment during fair conditions in HD patients. Whether this behaviour is due to a lack of recognition of social norms, an impairment in top-down inhibition, or an effect of antidopaminergic medication remains unclear.

Published: November 2021

Background: Coronavirus disease 2019 (COVID-19) cases in Germany, as in most other places in Europe or worldwide, are still highly prevalent. Vaccination rates currently remain low, putting cancer patients at a continued risk of infection with SARS-CoV-2, while prevalence of SARS-CoV-2 antibodies among cancer patients in Germany remains essentially unknown. Methods: Between August 2020 and February 2021, patients admitted to our hospital were prospectively enrolled in our COVID-19 biobank. Collected sera were analyzed for SARS-CoV-2-IgM/IgG using Elecsys Anti-SARS-CoV-2 assay. Results: One hundred and ten patients with cancer were included in this study. With 71 (65%) patients, most had active cancer treatment, mainly chemotherapy (56%). The most frequent diagnosis was gastrointestinal cancer (54%) with pancreatic cancer being the most common cancer type (24%). Hematologic malignancies were present in 21 patients (17%). Among the cancer patients first diagnosed during the pandemic, the rate of palliative treatment situations tended to be higher (76% vs. 67%, p = 0.17). A history of SARS-CoV-2 infection was documented in 15 (14%) patients; however, SARS-CoV-2 antibodies were detected in 10 (67%) patients only. Of the patients without a history of SARS-CoV-2 infection, none displayed SARS-CoV-2 antibodies. Conclusion: In the present single-center experience, a low serological prevalence of SARS-CoV-2 antibodies among cancer patients even after SARS-CoV-2 infection was found. The results support continued strict preventive measures as well as efforts toward faster vaccination, due to a low immunity level in the population.

Published: November 2021

Для оцінки морфологічних змін у тканинах пародонта при експериментальному гінгівіті з гіперергічним перебігом запального процесу було проведено моделювання цієї патології та експериментального гінгівіту без впливу на перебіг запальної реакції. Контролем слугували гістопрепарати тканин пародонта інтактних щурів.

Мета дослідження – вивчити морфологічні зміни тканин пародонта при експериментальному гінгівіті з гіперергічним перебігом запального процесу.

Матеріали і методи. Проведено морфологічні дослідження альвеолярного відростка із зубами та тканинами пародонта інтактних щурів і щурів із експериментальним гінгівітом віком 5–6 місяців. Мікроскопічно досліджували та фотодокументували зрізи товщиною 6–7 мкм, які були зафарбовані гематоксиліном та еозином.

Результати досліджень та їх обговорення. У щурів нормоергічної групи в епітеліальному пласті спостерігали розширення міжклітинних просторів, інфільтрацію нейтрофілами. Субепітеліальні тканини також були інфільтровані лейкоцитарними елементами. Найбільших змін зазнавали міжзубні ясенні сосочки, які були щільно інфільтровані нейтрофілами, місцями некротизовані. У щурів з експериментальним гінгівітом і гіперергічним перебігом запальної реакції спостерігали зміни епітелію, що відповідають неспецифічному запальному процесу. Практично усі міжзубні сосочки укриті виразками або частково некротизовані, епітелій підростає під некротичні маси, місцями наявна гіперплазія епітелію, особливо верхівок міжзубних ясенних сосочків. Окрім лейкоцитів, в епітелії ясен визначають мікрокісти з елементами ороговіння.

Висновки. Результати проведених гістологічних досліджень показали зміни структури ясен тварин при експериментальному гінгівіті без зміни реактивності організму. Зокрема, спостерігали деструктивні зміни епітеліального та сполучнотканинного шарів слизової оболонки; були наявні зміни епітелію: потовщення його зроговілого шару, ущільнення зернистого та остистого шарів; сполучної тканини: явища набряку, лейкоцитарної інфільтрації. При моделюванні гіперергічного гінгівіту в пародонті виникав запальний процес, який характеризувався розвитком значної лейкоцитарної інфільтрації епітеліального пласту; часто спостерігали як некротизацію ясенного сосочка, так і його гіперплазію з проліферацію епітелію.

Authors: Чарківський Т. Ю. , Авдєєв О. В.
Published: November 2021

Пародонтит є одним із найпоширеніших захворювань навколозубних тканин. Більшість протоколів його лікування передбачає використання антисептиків у пародонтальних кишенях. Ми пропонуємо вивчення можливості запровадження нового виробу медичного призначення – пародонтальних вкладок, насичених хлоргексидином, де кріоліофілізована ксеноочеревина виконуватиме роль депо антисептика. В даному дослідженні проводять вивчення здатності кріоліофілізованої ксеноочеревини насичуватись розчином хлоргексидину різних концентрацій, та зберігати його сухий залишок після проведення повторної процедури ліофілізації.

Мета дослідження – визначити здатність кріоліофілізованої ксеноочеревини свині насичуватись розчинами хлоргексидину різної концентрації, та здатність її утримувати сухий залишок розчину після повторної ліофілізації.

Матеріали і методи. У досідженні використовували кріоліофілізовану ксеноочеревину свинячого походження, виготовлену ТОВ «Інститут біомедичних технологій» товщиною 0,3 мм, та 20 % розчин хлоргексидину біглюконату, що в подальшому змішували з дистильованою водою для отримання розчинів різної концентрації – 2,5 % (1:7), 5 % (1:3) та 10 % (1:1). Пластинки кріоліофілізованої очеревини розміром 5х8 мм поділили на 4 групи по 30 штук у кожній. Кожну групу було зважено. На 10 хв групи занурювали у відповідний розчин хлоргексидину та знову зважували. Потім матеріал було ліофілізовано та проведено фінальне зважування.

Результати досліджень та їх обговорення. Після кожного етапу виготовлення пародонтальних вкладок, насичених хлоргексидином, їх зважували. Результати аналізу даних після замочування показали збільшення маси вкладок, порівняно з їх сухою масою, що свідчило про адсорбцію розчину ксеноочеревиною. Після проведення процедури ліофілізації маса вкладок із кожної групи зменшилась, однак все ще залишалась більшою, ніж маса сухої очеревини. Це свідчить про випаровування частини розчину під час ліофілізації та про наявність сухого залишку розчину хлоргексидину на вкладках. Масова частка цього залишку становила в середньому 13,77 % у першій групі вкладок (використовувався 2,5 % розчин хлоргексидину), 32,81 % у другій (5 % розчин хлоргексидину), 36,77 % у третій (10 % розчин хлоргексидину) та 57,4 % у четвертій групі (20 % розчин хлоргексидину).

Висновки. Кріоліофілізована ксеноочеревина має здатність насичуватись розчином хлоргексидину та зберігати його сухий залишок після повторної ліофілізації. Для подальших досліджень, зокрема в клініці, було прийнято рішення використовувати очеревину, яка була замочена у 10 та 20 % розчинах хлоргексидину з наступною ліофілізацією.
Memória hierofânica do catolicismo popular sertanejo e a sacralização da Serra do Horto, em Juazeiro do Norte – CE
Authors: Oliveira Paulo Wendell Alves de
Published: October 2021

A geografia da religião é um campo que nos permite diversas formas de abordagem do fenômeno religioso e sua relação com o espaço geográfico. A memória hierofânica constitui-se de uma base de leitura para a compreensão da constituição de grupos religiosos diversos sendo feita, especificamente neste trabalho, uma análise sobre o processo de espacialização do movimento do catolicismo popular sertanejo em Juazeiro do Norte, Ceará, tomando por recorte espacial a Serra do Horto, local de grande devoção que marca a relação do sagrado com esse grupo religioso. Tomamos a paisagem do sagrado e os ritos realizados pelos sujeitos como documentos que nos ajudam a compreender a constituição do próprio grupo e as formas de espacialização da crença que possuem e que marcam seu sistema simbólico. Ademais, associamos a esses documentos do sagrado a oralidade dos sujeitos pertencentes a essa crença, permitindo uma interpretação da forma simbólica do catolicismo popular sertanejo. Percebe-se que, em Juazeiro do Norte, dada a figura do Padre Cícero, ao ato hierofânico lá ocorrido e a paisagem existente nesse espaço, é permitida uma coerência de narrativa assumida pelo grupo em busca da “terra sem males”, que é uma das principais características que se associa a esse grupo religioso e constituiu o processo de espacialização simbólica nesse território, assumindo-o como sagrado ou sendo a própria “terra sem males”.
Violência contra mulheres: o perfil da vítima e do agressor em São Luís - MA

Published: October 2021

A pesquisa analisou a violência contra a mulher em São Luís-MA, traçando o perfil da vítima e agressor; e mapeou a distribuição espacial das agressões, através da emissão de medidas protetivas pela justiça. Utilizaram-se metodologias apoiadas no materialismo histórico e dialético, nas discussões de gênero e nas desigualdades intraurbanas. Foram empregados dados secundários, dos relatórios denominados “Pesquisa Social”, publicados entre 2009 e 2019, pelas 1ª e 2ª Varas Especiais de Violência Doméstica e Familiar contra a Mulher da Comarca de São Luís. O perfil da mulher vítima de violência doméstica, na sua maioria, são solteiras e/ou casadas, com idades que variam entre 26 e 43 anos, mãe de um ou mais filhos e sem renda fixa. Os agressores têm entre 26 e 34 anos, com diferentes profissões. Os atos violentos foram praticados majoritariamente por indivíduos que não têm mais relações afetivas com as vítimas e entre as motivações para a violência destacam-se o inconformismo com o fim da relação, ciúmes, dentre outros. A distribuição espacial da violência contra a mulher é heterogênea na escala intraurbana da capital maranhense, revelando certa desigualdade social, pois, a maioria das medidas protetivas, foi concedida para mulheres que habitam bairros pobres e periféricos, mas isso não quer dizer que a violência não esteja nos bairros com população de maior renda. Mesmo com o crescimento do acesso aos serviços especializados de denúncia e proteção às vítimas de violência de gênero, considera-se que ainda estão mal distribuídos pela cidade.

Published: October 2021

Neste artigo propõe-se discutir brevemente a evolução e a recente popularização dos pagamentos móveis no Brasil, em conjunto com o entendimento das relações entre as novas formas digitais e eletrônicas dos serviços financeiros com o crescimento das empresas de pagamento automático de pedágios em rodovias concedidas à iniciativa privada. Parte-se do pressuposto de que o objeto de estudo da geografia é o espaço geográfico, que pode ser brevemente definido enquanto conjunto indissociável de sistemas de objetos e sistemas ações. Além disso, entende-se que atualmente, no período técnico-científico-informacional, a informação é um vetor chave que orienta as ações. Estes são conceitos basilares que norteiam nosso método de interpretação. De acordo com os resultados obtidos, nota-se que as cinco principais empresas de pagamento eletrônico de pedágios sobre as quais a pesquisa se debruça – Sem Parar, ConectCar, Move Mais, Veloe e Taggy – apresentam crescimento nos últimos anos e buscam uma dupla expansão: de mercado, sendo um produto interessante mesmo para motoristas que não precisam trafegar por rodovias pedagiadas constantemente, e de função, se aproximando das empresas de pagamentos móveis de modo geral. Por fim, entende-se que essas novas formas de pagamentos móveis e digitais podem repercutir de múltiplas maneiras nos usos do território brasileiro na contemporaneidade.
Using morphometric and geomorphic indices to assess Western São Francisco Craton neotectonic traces
Authors: Bragança Mário Teixeira Rodrigues , Barros Luiz Fernando de Paula , Oliveira Déborah de
Published: October 2021

Recently, geomorphometric properties of river networks and catchments have been described and applied as an efficient tool in the investigation of the landforms' response to neotectonics. Geometric parameters of the Cotovelo River catchment extracted from an Alos-Palsar digital elevation model were used to compute morphometric and geomorphic indices to investigate whether the bedrock structure and recent active tectonics influence the local drainage network. The Cotovelo catchment is situated in the Middle to Upper Proterozoic western foreland basin of the São Francisco craton, in northwestern Minas Gerais, Southeastern Brazil; it is presumed to be a stable piece of earth’s crust. The automatically generated streams were processed at the sub-catchment scale to calculate the hypsometric integral, relief ratio, stream frequency, and drainage density morphometric indices as well as supported a geomorphic study based on the basin shape, asymmetry factor, valley floor width-to-height ratio, mountain front sinuosity, transverse topographic symmetry factor, and stream-length gradient index. Achieved results revealed recent and low-rate tectonic activity and structural control on the fluvial morphology. Prominent knickpoints, aligned with mapped fault scarps, disclose straight erosive fronts away from stratigraphic borders, indicating these features are unrelated to lithological changes. Despite the catchment location, the area exhibits impressive fluvial anomalies, and dissection occurs preferentially along ancient faults and fractures densely occurring in the rocky strata. Channel parallelism in context of medium to high relief and steep slopes, remarkably structurally drive fluvial dissection, asymmetric and elongated drainage catchments, and aligned landforms suggest neotectonic influence on the drainage network.

Published: October 2021

Dados de 5,6 milhões de alunos de escolas públicas que pontuaram em todas as provas do Exame Nacional do Ensino Médio (ENEM), de 2012 a 2018, foram analisados. O desempenho dos alunos foi agrupado por escola e por zona, correlacionado com variáveis socioeconômicas e escolares, e representado em diferentes unidades administrativas (município, micro e mesorregiões, estados e regiões). O problema das unidades de áreas modificáveis e as falácias também foram avaliados na comparação entre os diferentes níveis de agregação. Constatou-se que a pontuação média dos concluintes melhorou no período, mas o número total de alunos com elevada proficiência não aumentou da mesma forma. Dentre as variáveis analisadas, a renda familiar per capita apresentou maior correlação com o desempenho neste teste educacional. Embora a quantidade de dados analisados seja expressiva e seus resultados tenham permitido identificar as áreas de melhor desempenho, considerou-se que o baixo percentual de participação no exame pode comprometer o potencial de utilização deste teste educacional para avaliar a qualidade educacional das escolas públicas brasileiras. De modo geral, as menores proficiências do Brasil ocorreram nos municípios e microrregiões do Norte e do Nordeste do Brasil. Nestes agrupamentos territoriais, a renda per capita média é frequentemente menor. Apesar dos valores de correlação terem aumentado nos zoneamentos de maior agregação, a percepção desta associação entre as variáveis diminuiu nas representações cartográficas.

Background

Sodium‐glucose cotransporter 2 inhibitors improve cardiovascular outcomes in patients with diabetes with and without heart failure (HF). However, their influence on sympathetic nerve activity (SNA) remains unclear. The purpose of this study was to evaluate the effect of sodium‐glucose cotransporter 2 inhibitors on SNA and compare the responses of SNA to sodium‐glucose cotransporter 2 inhibitors in patients with type 2 diabetes with and without HF.

Methods and Results

Eighteen patients with type 2 diabetes, 10 with HF (65.4±3.68 years) and 8 without HF (63.3±3.62 years), were included. Muscle SNA (MSNA), heart rate, and blood pressure were recorded before and 12 weeks after administration of dapagliflozin (5 mg/day). Sympathetic and cardiovagal baroreflex sensitivity were simultaneously calculated. Brain natriuretic peptide level increased significantly at baseline in patients with HF than those without HF, while MSNA, blood pressure, and hemoglobin A1c did not differ between the 2 groups. Fasting blood glucose and homeostatic model assessment of insulin resistance did not change in either group after administering dapagliflozin. MSNA decreased significantly in both groups. However, the reduction in MSNA was significantly higher in patients with HF than patients with non‐HF (−20.2±3.46 versus −9.38±3.65 bursts/100 heartbeats;
P
=0.049), which was concordant with the decrease in brain natriuretic peptide.

Conclusions

Dapagliflozin significantly decreased MSNA in patients with type 2 diabetes regardless of its blood glucose‐lowering effect. Moreover, the reduction in MSNA was more prominent in patients with HF than in patients with non‐HF. These results indicate that the cardioprotective effects of sodium‐glucose cotransporter 2 inhibitors may, in part, be attributed to improved SNA.

Background

Dysglycemia at acute myocardial infarction (AMI) is common and is associated with mortality. Information on other outcomes is less well explored in patients without diabetes in a long‐term perspective. We aimed to explore the relationship between admission glucose level and long‐term outcomes in patients with AMI without diabetes in a nationwide setting.

Methods and Results

Patients without diabetes (n=45 468) with AMI registered in SWEDEHEART (Swedish Web–System for Enhancement and Development of Evidence‐Based Care in Heart Disease Evaluated According to Recommended Therapies) and admission glucose ≤11 mmol/L (≤198 mg/dL) were followed for outcomes (AMI, heart failure, stroke, renal failure, and death) between 2012 and 2017 (mean follow‐up time 3.3±1.7 years). The association between categorized glucose levels and outcomes was assessed in adjusted Cox proportional hazards regression analyses (glucose levels 4.0–6.0 mmol/L [72–109 mg/dL] as reference). Further nonfatal complications and their associated mortality were explored (patients without events served as a reference). A glucose level of 7.8–11.0 mmol/L (140–198 mg/dL) was associated with hospitalization for heart failure (hazard ratio [HR] 1.40 [95% CI, 1.30–1.51],
P
<0.001), renal failure (1.17; 1.04–1.33,
P
=0.009), and death (1.31; 1.20–1.43,
P
<0.001), but not with recurrent myocardial infarction (0.99; 0.92–1.07,
P
=0.849) or stroke (1.03; 0.88–1.19,
P
=0.742). Renal failure had the strongest association with future mortality (age‐adjusted HR 4.93 [95% CI, 4.34–5.60],
P
<0.001), followed by heart failure (3.71; 3.41–4.04,
P
<0.001), stroke (3.39; 2.94–3.91,
P
<0.001), and myocardial infarction (2.08; 1.88–2.30,
P
<0.001).

Conclusions

Elevated glucose levels at AMI admission identifies patients without diabetes at increased risk of long‐term complications: in particular, hospitalization for heart and renal failure. These results emphasize that glucose levels at admission could be useful in risk assessment after myocardial infarction.
Religious and Secular Coping Strategies of Reappraisal
Authors: Riegel Ulrich , Unser Alexander
Published: October 2021

In times of disaster, religion is said to be a powerful resource of meaning-focused coping. If offers motifs, symbols, and stories to reappraise situations and thereby ascribe meaning to them. Aside from religion, in modern times secular resources are feasible for meaning making during disaster as well. Empirical instruments that assess both religious and secular types of meaning-focused coping, however, are not available. Relevant instruments focus exclusively on either religious or secular coping. This paper addresses this desideratum by supplementing the RCOPE-scales of reappraisal with relevant scales of secular reappraisal. Three scales – Trust in Science, Consequences of Lifestyle, and Reappraisal of Science’s Power – have been constructed and tested on a sample of university students and staff members coping with the Corona pandemic. CFA shows a satisfactory fit for the supplementing instrument when Trust in Science is removed from the analysis. Correlation analysis with scales of religiosity (Centrality of Religiosity and Post-Critical Belief) indicates a good external validity of the new instrument. In consequence, the two supplements of Consequences of Lifestyle and Reappraisal of Science’s Power facilitate assessment of secular meaning-focused coping aside with relevant religious coping, while the Trust in Science Reappraisal scale needs further development.
Reconciled Community

Published: October 2021

Recent experience suggests that there is insufficient reflection on the ‘why’ of mission among missionary pioneers, that is, on the soteriology that underpins missional practices in the West. This article argues, first, that a social view of salvation is the best way to make theological sense of missional community formation (mcf). Second, this implied soteriology is further developed as an integrative lens on various dimensions of salvation in Christianity. Third, it is argued that this relocation of mcf in this social view of salvation offers rich opportunities for witness, and thus a potential remedy against soteriological embarrassment.

Published: October 2021

Wire and arc additive manufacturing (WAAM) is considered to be an economic and efficient technology that is suitable to produce large-scale and ultra-large-scale metallic components. In the past two decades, it has been widely investigated in different fields, such as aerospace, automotive
and marine industries. Due to its relatively high deposition rate, material efficiency, and shortened lead time compared to other powder-based additive manufacturing (AM) techniques, wire and arc additive manufacturing (WAAM) has been significantly noticed and adopted by both academic researchers
and industrial engineers. In order to summarize the development achievements of wire and arc additive manufacturing (WAAM) in the past few years and outlook the development direction in the coming days, this paper provides an overview of 3D metallic printing by applying it as a deposition
method. The review mainly focuses on the current welding systems, software for tool path design, generation, and planning used in wire and arc additive manufacturing (WAAM). In the end, the state of the art and future research on wire and arc additive manufacturing (WAAM) have been prospected.

China is a big coal producing country, there are a lot of coal gangue piled up. The zeolite X was synthesized by alkali melting and hydrothermal method based on the coal gangue from Chifeng city, Inner Mongolia. The obtained zeolite X sample is characterized by X-ray diffraction, SEM,
EDS spectrum and IR which showed the X zeolite is an octahedral structure with complete crystal shape and uniform grain size. The results of BET showed the specific surface area of zeolite X is 354.8 m2/g and the minimum pore size is 3.8 nm which indicated that the zeolite X belongs
to mesoporous materials. The adsorption conditions of the zeolite X adsorbent on copper ions were optimized. A solution containing Cu2+ ions with an initial concentration of 300 mg/L was added to the zeolite X with a dosage of 0.1 g and the initial pH value of the solution was adjusted
to 6. Then the solution was oscillated for 120 min at 225 r/min. The maximum adsorption capacity and removal rate were 148.6 mg/g and 99.1%, respectively. The adsorption mechanism was discussed by adsorption kinetics and thermodynamics. The quasi-second order kinetic equation can be well used
to describe the adsorption kinetics of zeolite X to Cu2+ (R2 = 0.9994) and Langmuir can well describe the adsorption behavior of zeolite X to Cu2+ (R2 = 0.9995) which showed the adsorption is a monolayer of chemical adsorption. The
adsorption capacity of zeolite X to Cu2+ is about 4.0 times that of coal gangue, indicating that the zeolite X has good adsorption capacity.

Breast cancer has a high incidence and causes death worldwide, especially in women. Melatonin is a hormone that affects the prevention and treatment of tumors, and its effects have improved when associated with a modified release system. Thus, this study aimed to investigate the effects
of a microemulsined system containing melatonin and PEG 400 on cellular oxidative stress and viscosity in the co-culture of blood mononuclear cells (MN) and MCF-7 cells. The microemulsion system containing melatonin and PEG 400 was developed from a mixture of the oil and aqueous phases and
stabilized with surfactants. Blood mononuclear cells (MN) obtained from voluntary donors and MCF-7 cells (ATCC) were maintained in culture in CO2 for 24 hours treated with melatonin or with the microemulsion system containing melatonin and PEG 400. The flow and viscosity curves
were evaluated using a rheometer, and the oxidative stress was evaluated by superoxide release and superox-ide dismutase (SOD) determination by colorimetric methods. The microemulsion system containing melatonin and PEG 400 showed a stable, translucent, and homogeneous property. The viscosity
was higher in MCF-7 cells and MN cells when in the presence of a microemulsion system containing melatonin and PEG 400. The rheological behavior of MN and MCF-7 cells did not change in the presence of melatonin. The microemulsion system with melatonin and PEG 400 increased SOD levels in cultures
of MN cells co-cultured with MCF-7 cells. These results suggest that the microemulsified system interferes with the oxidative metabolism of MN cells in co-culture with MCF-7 cells, with a reduction in SOD enzyme levels without changing superoxide levels, which could probably be favorable to
the antitumor action of blood MN cells.
