BackgroundEnteroviruses have the potential to cause both high morbidity and mortality especially in children. High season in Norway is between August and November, but this seasonality was interrupted by the COVID-19 pandemic.MethodsIn this study, we describe the enterovirus surveillance in Norway before and during the COVID-19 pandemic including the years from the start of 2016 until the end of 2022. Screening of enterovirus was performed by both laboratory developed methods and FilmArray® ME Panel. Relevant samples were typed, mostly by VP1 sequencing.ResultsSeventy-four percent of all cases occurred in infants under five years of age. A significant reduction in positive cases was observed during the peak years of the COVID-19 pandemic compared to the years before. Pre-pandemic, a wide range of types from all four enterovirus species were detected. During the years with COVID-19 infection control measures, significantly fewer enterovirus types were found along with a substantial reduction in the detection rate.ConclusionEnterovirus surveillance discovered a large amount of different types mainly affecting infants. The positivity rate was markedly reduced during the pandemic in 2020-2022 and fewer types occurred.

Published: January 2024

Interrupted lung angiogenesis is a hallmark of bronchopulmonary dysplasia (BPD); however, druggable targets that can rescue this phenotype remain elusive. Thus, our investigation focused on amphiregulin (Areg), a growth factor that mediates cellular proliferation, differentiation, migration, survival, and repair. While Areg promotes lung branching morphogenesis, its effect on endothelial cell (EC) homeostasis in developing lungs is understudied. Therefore, we hypothesized that Areg promotes the proangiogenic ability of the ECs in developing murine lungs exposed to hyperoxia. Lung tissues were harvested from neonatal mice exposed to normoxia or hyperoxia to determine Areg expression. Next, we performed genetic loss-of-function and pharmacological gain-of-function studies in normoxia- and hyperoxia-exposed fetal murine lung ECs. Hyperoxia increased Areg mRNA levels and Areg+ cells in whole lungs. While Areg expression was increased in lung ECs exposed to hyperoxia, the expression of its signaling receptor, epidermal growth factor receptor, was decreased, indicating that hyperoxia reduces Areg signaling in lung ECs. Areg deficiency potentiated hyperoxia-mediated anti-angiogenic effects. In contrast, Areg treatment increased extracellular signal-regulated kinase activation and exerted proangiogenic effects. In conclusion, Areg promotes EC tubule formation in developing murine lungs exposed to hyperoxia.

Published: January 2024

Cr-doped Al2O3 spheres with strong red emission were produced using a simple laser processing approach with a 50 W continuous CO2 laser. Structural characterization revealed that the produced spheres were monophasic, comprising the α-Al2O3 phase. Photoluminescence (PL) studies indicated that the observed red emission originates from multiple Cr3+ optical centers being dominated by the 2E → 4A2 transition (R-lines), with a further contribution from the parity and spin forbidden 2T1 → 4A2 transition (R′-lines). The identification of additional radiative recombination from chromium ion pairs (N-lines) evidences that the produced samples are heavily doped. As such, energy transfer processes between the different chromium optical centers are seen to take place, as suggested by the lifetime decay analysis. PL excitation revealed that the room temperature luminescence is preferentially populated via the spin-allowed 4A2 → 4T2,4T1 transitions and by the parity and spin-forbidden 4A2 → 2T2 (B-lines), 2T1 (R′-lines), 2E (R-lines). Such results demonstrate that the present synthesis method is able to deliver high-optical-quality Al2O3:Cr crystals in a fast and simple way, with potential interest for optical, sensing, or lasing applications.

The world cereal production and supply as well as their trade, stock and losses are important indicators of the world market of cereals. They play a huge role in ensuring food security. The aim of this research is to identify the relation of the indicators of the world grain crops market (production, supply, losses, trade, stocks) and the level of malnutrition Prevalence of Undernourishment (PoU) among the world's population. Based on data from the Food and Agriculture Organization of the United Nations (FAO), a correlation-regression analysis was conducted between indicators of the global grain crops market, in particular: the wheat market, the fodder market of grain crops, the rice market and PoU of the world population for the period 2013/14 – 2020/2021 marketing years. It has been proven that there is a close, statistically reliable relationship between the above mentioned indicators, except for grain stocks and POU. The analysis of the world cereal market showed that among the indicators characterizing its conditions, the indicator trade in grain crops (r = 0.851; D = 0.724; F = 3.968, (F > F t ); z = 1.26; rL = 0.37; rU = 0.97) has the highest level of correlation. It was found that with an increase in the volume of world cereal trade by 1 million tons, the PoU level will increase by 0.018%. A review of literary sources proves that the problem of ensuring food security, in particular with regard to reducing the level of starvation and malnutrition, cannot be solved only by fighting climate change, overcoming socio-economic and military problems, fighting pandemics, etc. Its solution to a large extent depends on fair, uniform export and import of food products, as evidenced by the calculations. A separate direction for solving the problem of the spread of malnutrition is the elimination of the policy of highly developed countries regarding the application of individual sanctions against countries with high PoU values, in particular, the Central African Republic, Madagascar, Haiti, Afghanistan, Chad, Congo, Lesotho, Liberia, Mozambique, etc.

Published: January 2024

Produksi semen semakin meningkat seiring dengan peningkatan pemakaian beton. Hal ini menimbulkan masalah karena untuk setiap ton semen yang diproduksi, akan menimbulkan lebih dari tigaperempat ton CO2 yang dapat meningkatkan pemanasan global. Oleh sebab itu reduksi penggunaan semen harus dilakukan, salah satunya dengan membuat beton tanpa semen. Tahun 1978, Joseph Davidovits menemukan bahwa cairan alkalin bisa mereaksikan silikon (Si) dan alumunium (Al) dalam abu terbang menghasilkan binder untuk merekatkan agregat membentuk beton Geopolymer. Penelitian ini menggunakan beton konvensional dengan menggunakan semen sebagai beton control. Kemudian dibuat beton geopolymer dengan penggunaan agregat yang sama, dengan activator (NaOH: Na2SiO3 dengan perbandingan 2:5), membuat campuran dengan menggunakan prekursor -Abu terbang dan Abu sekam padi dengan perbandingan 100%:0%(BG0), 90%:10%(BG1), 80%:20%(BG2) dan 70%:30%(BG3). Selanjutnya dibuat perbandingan Aktivator dan Prekursor 4 : 3. Hasil pengujian kuat tekan pada umur 7 dan 28 hari menunjukkan bahwa kuat tekan beton normal lebih rendah dibanding BG0 dan tidak berbeda signifikan dengan BG1. Sedangkan ratio hasil tekan 7 dan 28 hari bersesuaian dengan ratio kuat tekan 7 dan 28 hari PBI”71 yakni 0.6. Selanjutnya setiap penambahan Abu Sekam Padi 10 % untuk menggantikan abu terbang akan menurunkan kuat tekan sebesar 2 - 3 MPa.
Cement production is increasing along with the increase in concrete use. This creates a problem because every ton of cement produced will emit more than three-quarters of a ton of CO2 which can increase global warming. Therefore, cement use must be reduced, one of which is by making cement-free concrete. In 1978, Joseph Davidovits discovered that alkaline liquid could react with silicon (Si) and aluminum (Al) in fly ash to produce a binder to bond aggregates to form Geopolymer concrete. This research uses conventional concrete using cement as control concrete. Then geopolymer concrete is made using the same aggregate, with an activator (NaOH: Na2SiO3 with a ratio of 2:5), making a mixture using precursors -fly ash and rice husk ash with a ratio of 100%:0%(BG0), 90%:10 %(BG1), 80%:20%(BG2) and 70%:30%(BG3). Next, a 4:3 comparison of Activator and Precursor was made. The results of compressive strength testing at 7 and 28 days showed that the compressive strength of normal concrete was lower than BG0 and not significantly different from BG1. Meanwhile, the compressive yield ratio of 7 and 28 days corresponds to the compressive strength ratio of 7 and 28 days PBI"71, namely 0.6. Furthermore, each addition of 10% Rice Husk Ash to replace fly ash will reduce the pressure by 2 – 3 MPa..

Authors: Ferreira Eliana Lúcia 
Published: January 2024

Este estudo focaliza a dança esportiva em cadeira de rodas para as pessoas com deficiência física, tendo como objetivo analisar como um corpo se aloca/ se apropria de uma cadeira de rodas e produz novos movimentos artísticos, e principalmente como estes movimentos artísticos foram sendo estruturados e solidificados historicamente numa nova proposta esportiva. A trajetória metodológica da presente pesquisa desenvolveu-se a partir da coleta e análise de dados, oriundos de uma experiência de vinte e dois anos com os Grupo de dança esportiva em cadeira de rodas. As informações foram obtidas através de registros em vídeos das coreografias apresentadas pelos diversos grupos de dança em cadeira de rodas no decorrer do campeonato brasileiro dos anos de 2022 e 2023. Também realizamos entrevistas formais com dançarinos e coreógrafos destes mesmos grupos. Desta forma observamos que a modalidade de dança esportiva possuí suas especificidade. E estas especificidades foram possíveis devido às inúmeras experiências de novos movimentos corporais com a cadeira de rodas. E estas experiências ao longo dos anos alargaram as aptidões de cada corpo, do jeito que o corpo é, sem transferências rígidas de modelo. Sendo assim concluímos que o esporte se traduz como um fenômeno social de grande abrangência e visibilidade. Todavia, vê-se um esforço para superarem as dificuldades encontradas e os preconceitos existentes em suas trajetórias de vida e esportiva, a fim de conseguirem pertencer, crescerem na modalidade, serem reconhecidos e valorizados no esporte que praticam, pois o espaço esportivo é, delimitado e constituído por relações de poder.
