The role of dietary flavonoids for modulation of ATP binding cassette transporter mediated multidrug resistance
Authors: Teng Hui , Deng Hongting , He Yuanju , Lv Qiyan , Chen Lei
Published: December 2021

Flavonoids are widely existing compounds with enormous pharmacological effects from food and medicine. However, the low bioavailability in intestinal absorption and metabolism limits their clinical application. Intestinal efflux ABC (ATP binding cassette) transporters, including P‐glycoprotein (P‐gp), breast cancer resistance protein (BCRP) and multidrug resistance‐ associated proteins (MRPs), act as ’’pumping doors” to regulate the efflux of flavonoids from intestinal epithelial cells into the intestinal cavity or the systemic circulation. The present review describes the critical effect of ABC transporters involved in the efflux of flavonoids which depend on its efflux direction. And the role of flavonoids for modulation of intestinal ABC transporters was emphasized and several examples were given. We summarized that the resistance effect of flavonoid‐mediated multidrug on ABC transporters may influence the bioavailability of drugs, bioactive ingredients and/or toxic compounds upon dietary uptake. Meanwhile, flavonoids functionalized as reversing agents of the ABC transporter maybe an important mechanism for unexpected food‐drug, food‐toxin or food‐food interactions. The overview also indicates that elucidation of the action and mechanism of the intestinal metabolic enzymes‐efflux transporters coupling will lay a foundation for improving the bioavailability of flavonoids in vivo and increasing their clinical efficacy.

Through an interdisciplinary conversation in the context of the project: Food Insecurity in Times of Climate Change: Sharing and Learning from Bottom-up Responses in the Caribbean Region, we expose the voices, history and knowledge of local communities and activists in Barbuda, Belize, Colombia (San Andres and Providencia), Jamaica and Puerto Rico to the food insecurity and ecological crisis in the Caribbean. The composite effect of climate injustice and the COVID-19 pandemic is outlined as anthropogenic crises that thrive on inequality and dependency in the Caribbean. The community experiences of the project countries reveal an emergence of knowledge and diverse ways of producing food and relating to the environment as alternatives to development. It is a criticism of the solutions imposed from above that ignore the knowledge, needs and practices of popular ecologies in the Caribbean.
Conflictos ambientales en Centroamérica y las Antillas: un rápido toxic tour
Authors: Martínez-Alier Joan
Published: December 2021

In political ecology there is need for more empirical work on the large world resistance movement born from the environmentalism of the poor and the indigenous. The environmental conflicts collected in the Environmental Justice Atlas (www.ejatlas.org), 3,300 in October 2020 include about 130 from Mexico and 120 from Central America and the Caribbean, each one with a data sheet of 5 to 6 pages. This article puts Mexico aside because it is well covered in this issue of Ecología Política. I focus on Central America and the Caribbean briefly analyzing about twenty conflicts. Many of them are failures in environmental justice but some are encouragingly successful: for instance, Pacific Rim in El Salvador; Cerro Blanco in Guatemala and El Salvador; Crucitas in Costa Rica, and the Canal of Nicaragua that seemingly has been stopped. Also cases against Cemex in Puerto Rico and the Dominican Republic, the maroon people of Cockpit Country in Jamaica against bauxite mining, and Vieques in Puerto Rio against militarization. In the Conclusion I list some characteristics of the political ecology of the region.

Authors:   Sofia University, Aleksieva Lyubka , Mirtschewa Iliana ,   Sofia University, Radeva Snezhana ,   Sofia University
Published: December 2021

Early STEM education has a great potential to support children’s development in constructing their own knowledge, in designing, discussing and testing ideas and finding solutions to different problems. Significant role in achieving the goals of STEM education is played by the teacher, who scaffolds the learning process, builds a creative learning environment, provokes children with open questions and guides them to test their hypothesis as young scientists, mathematicians, engineers and technology users. Preschool teachers’ knowledge and perspectives could seriously influence their practices in STEM education and respectively, the fulfilment of STEM learning outcomes. It is very important to explore in depth teachers’ views and experiences thus to plan and provide appropriate courses for their academic preparation or continuous professional development. While reviewing some popular misconceptions for STEM education amongst teachers, this paper presents the results of pre- and post-interviews conducted with teachers from Bulgaria in the framework of the European multilateral Erasmus+ project №2018-1-TR01-KA203-059568 “STEM for Pre-schoolers and Their Families” (PARENTSTEM) (2018–2021). The overall goal of this project was to increase family involvement in the STEM education process of early childhood children specifically coming from low socio-economic status. As a part of this goal implementation, the project aimed to extend conceptual and pedagogical knowledge of early childhood teachers on STEM. In the frame of the project the preschool teachers-participants in the study were provided with three teacher trainings (two international and one national) and were additionally supported with the intellectual outputs of the project. This paper attempted to identify teachers’ preliminary knowledge, awareness and attitudes towards STEM conceptualization and pedagogy and to describe the relative influence of the project teacher trainings and activities on them. The results of the research unambiguously demonstrated the need for training of preschool teachers in terms of STEM education, outlining the main focuses to be considered when constructing STEM courses intended for preschool teachers.

Published: December 2021

Today we all live in an extremely dynamic world which provokes a variety of challenges related not only to health but also to education and social isolation. It appears that many young people are motivated and ambitious to shape their own future gaining experience and confidence during the school years. Many of their ideas have a creative and rational potential which triggers socially useful initiatives and projects on regional, national or international level. Participation in eco projects, volunteering and supporting social causes combines studying and practical activities and, thus, raises the quality of education and breaks its traditional character. And when innovation is also included, the result is predetermined and winning. Using an integrated system for ecological management, “Peyo Yavorov” Secondary School has encouraged students, teachers and parents to participate in eco initiatives for more than 20 years. This enriches their knowledge and improves the environment. Focusing on the ecological education ensures better understanding of the environmental problems with their local and global impact. Different approaches are used for developing key competences which creates later an active, healthy and environmental-friendly behavior. Activities in the eco field have proved to be effective as means of raising sensitivity and responsibility aiming at the change of one’s attitude – towards themselves, the others and the environment.

Authors: Yuan Baoquan , Zhang Panpan
Published: December 2021

This paper focus on the Cauchy problem of the 3D incompressible magneto-micropolar equations with fractional dissipation in the Sobolev space. Liu, Sun and Xin obtained the global solutions to the 3D magneto-micropolar equations with $\alpha=\beta=\gamma=\frac{5}{4}$. Deng and Shang established the global well-posedness of the 3D magneto-micropolar equations in the case of $\alpha\geq\frac{5}{4}$, $\alpha+\beta\geq\frac{5}{2}$ and $\gamma\geq2-\alpha\geq\frac{3}{4}$. In this paper, we establish the global well-posedness of the 3D magneto-micropolar equations with $\alpha=\beta=\frac{5}{4}$ and $\gamma=\frac{1}{2}$, which improves the results of Liu-Sun-Xin and Deng-Shang by reducing the value of $\gamma$ to $\frac{1}{2}$.

Sospeso tra due mondi: il velo di San Giusto tra Bisanzio e Trieste
Authors: Bevilacqua Livia
Published: December 2021

This article aims to a preliminary reassessment of the silk veil preserved in the Treasury of Trieste cathedral. The cloth is unparalleled in Byzantine as well in western medieval art, in that it is painted with tempera on both sides. It depicts a youthful martyr in a court costume, and bears an inscription that identifies the saint as St. Just. Since its alleged recovery from a reliquary in the early nineteenth century, the cloth has been often addressed by the scholars, who ascribed it either to a Byzantine or to a local master and dated it between the eleventh and the fourteenth century.
Despite being referred to in several more general studies, it has been rarely considered individually. In this paper I address the many questions that the Trieste veil raises, including problems of chronology, provenance, function, and iconography. After careful observation and based on both primary sources and visual evidence, I argue that it was produced in Byzantium, possibly at an early date, to serve as a liturgical implement; later, it was brought to the West, where the saint was given a new identity and the cloth was reused as a banner after being painted on the reverse.

Seismic Attributes Aided Characterization of Margin Backstepping and Advance along Isolated Carbonate Sequences, Sirt Basin, Libya
Authors: Abdalla Muneer A.
Published: December 2021

Isolated carbonate platforms are common and contain significant hydrocarbon accumulations, particularly in the tectonically complex Sirt Basin in Libya. This study investigates the margin cyclicity of two carbonate stratigraphic sequences developed on an isolated carbonate platform in the NW Sirt Basin using 3-D post-stack seismic volume and wireline log data. The two sequences (sequences 4 and 5) are bounded by unconformity surfaces from the base and top. Seismic attributes show that each sequence displays a cycle of margin backstepping followed by margin advance for several hundred meters. This study concludes that the margin backstepping and advance are mainly influenced by sea-level changes. A rapid sea-level rise caused the backstepping, whereas slow sea-level rise caused the margin advance.

Isolated dilatation of the aortic root and/or ascending aorta is a rare but well-known cardiovascular manifestation, can be caused by a variety of congenital or acquired conditions; that lead to the weakening of the aortic wall. The study aimed to detect the cause and the rate of the aortic root dilatation in children and adolescents, and to assess the effect of the Beta-adrenergic blockers in preventing further dilatation in the aortic root. A case series study was perform with five years of follow-up at Al-Hawary General Hospital, National Benghazi Cardiac Center. A total of 91 patients were seen with ascending aortic dilatation and/or root dilatation during the period from 6/2016 - 6/2021 included in the study diagnosed by clinical examination, chest x-ray, and echocardiogram. The diagnosis in 34/91(37%) was Tetralogy of fallout (TOF) and truncus arteriosus, 57/91 (63%) was dilated aortic root, 25/57 (44%) bicuspid aortic valve (BAV), 22/57 (38.5%) Marfan syndrome, 4/57(7%) Noonan syndrome, 2/57(3.5%) Turner syndrome, 3/57(5%) Ehlers-Danlos syndrome, 1/57(2%) idiopathic. Follow-up results of three months – five years: 57/91 patients with aortic root dilatation were followed up, none of the Marfan syndrome and Ehlers-Danlos syndrome patients who received beta-blockers had shown progression in the dilatation of the aortic root, and all patients who had bicuspid aortic valve did not show any progression in the dilatation without using medication. Conclusions: Dilated aortic root is a common finding in Marfan syndrome, bicuspid aortic root, and Ehlers-Danlos syndrome, and its progress could be decreased by using beta-adrenergic blockers in rapidly progressing dilation.

Published: December 2021

Climate change is recognized as a significant man-made global environmental challenge and it is also treated as threat. It may alter the distribution and quality of natural resources. Considering the vulnerabilities of forests and irreversible impacts of climate change on forests, long term planning for forest conservation and management is the urgent need of the hour to ensure and maintain the long-term mitigation potential of forests. In this study multi-disciplinary literature review, interviews with researchers in a variety of related fields, and consultation meetings with selected practitioners at the national, regional, and local levels were conducted. The findings of study highlighted the current status of knowledge, strengths, gaps and constraints in research pertaining to climate change adaptation and mitigation aspects of forests in India.

Typical bacterial symptoms, water-soaking brown and black leaf spots with yellow halo, were observed on watermelon seedlings in nursery and field of Gyeongnam and Jeonnam provinces. Bacterial isolates from the lesion showed strong pathogenicity on watermelon and zucchini. One of them was rod-shaped with 4 polar flagella by observation of transmission electron microscopy. They belonged to LOPAT group 1. The phylogenical trees with nucleotide sequences of 16S rRNA and multi-locus sequencing typing with the 4 house-keeping genes (gapA, gltA, gyrB, and rpoD) of the isolates showed they were highly homologous to Pseudomonas syringae pv. syringae and grouped together with them, indicating that they were appeared as P. syringae genomospecies group 1. Morphological, physiological, and genetical characteristics of the isolates suggested they are P. syringae pv. syringae. We believe this is the first report that P. syringae pv. syringae caused leaf spot disease on watermelon in the Republic of Korea.
Upper tropospheric energetics of standing eddies In wave number domain during contrasting Monsoon activity over India

Published: December 2021

The upper tropospheric energetics of the standing eddies in wave number domain during contrasting monsoon' activity over India have been investigated. Two normal monsoon years (1970. 1971) and two drought monsoon years (1972, 1979) are considered for a comparative study, Energy equations of Saltzman (1957) are used to compute wave-wave Interaction and wave to zonal mean flow Interaction. Analysis of the results show that the standing eddies in the region of tropical easterlies (5°S-24 .2°N) have larger kinetic energy than those in the region of southern hemispheric, westerlies (24.2°S-5°S). Wave to zonal mean flow interaction of all waves (waves 1-15) Indicate that the standing eddies are a source of kinetic energy to zonal mean flow ID the region of easterlies and there sink of kinetic energy to zonal mean flow in the region of westerlies. In the region of easterlies planetary standing waves (waves 1-2) are the major kinetic energy source to other standing waves and wave-wave Interaction of all waves leads to positive Imbalance of kinetic energy during normal monsoon years (1970, 1971) and negative imbalance, of kinetic, energy during drought monsoon years (1972, 19~9). In the region of westerlies the imbalance of kinetic energy IS negative during normal monsoon years and positive during drought monsoon years.

THE 500 HPA SUB-TROPICAL ANTICYCLONE DURING APRIL AND MAY 1988 AND THE WEATHER OVER INDIA
Authors: SINGH RANJIT
Published: December 2021

The sub-tropical ridge at 500 hPa in April has a considerable synoptic scale fluctuation. In April 1988, it showed a steady southward displacement to the equator. In May 1988, a fresh sub-tropical anticyclone formed in northern latitudes by the anticyclonic recut-mg of the dry northwesterlies of extra-tro-pical origin. By extending southward the northerlies ushered a dry spell extensively to the south of the sub-tropical ridge (STR). This was an event contrary to the normal northward progress of equatorial weather belt and the STR. Thus the mean April 500 hPa ridge does not provide a logical parameter for long range forecast-ing of the southwest (SW) monsoon rainfall over India.
TRENDS AND PERIODICITIES OF SURFACE AIR TEMPERATURE OF DELHI
Authors: LAL BHUKAN
Published: December 2021

Seasonal and annual surface air temperature of Delhi has been analysed for 90-year period (1901-1990) for finding trends and periodicities. The analysis revealed that frequency distribution of all the four seasons as well as of annual time series is normal. Markov linear-type of persistence is observed in pre and post-monsoon seasons. Recent period {1961-1990) averages of temperature are significantly lower than the long period means in respect of annual, monsoon and pre-monsoon seasons. Decreasing trend is noticed in monsoon and annual temperature time series. Low-pass filter analysis suggests that the trend is not linear but oscillatory consisting periods of 10 years or more.

Published: December 2021

Global Navigation Satellite System (GNSS) is widely used now days in variety of applications. The observation file for the near realtime estimation of Integrated Precipitable Water Vapour (IPWV) received at the ground-based receiver is mixed with ambiguities. Multi-path effects affect the positional accuracy as well as range from satellite to ground based receiver of the system. The designing of the antenna suppress the effect of multi-path, cycle slips, number of observations, and signal strength and data gaps within the data streams. This paper presents the preliminary data quality control findings of the Patch antenna (LeicaX1202), 3D Choke ring antenna (LeicaAR25 GNSS) and Trimble Zephyr antenna (TRM 39105.00). The results shows that choke ring antenna have least gaps in the data, cycle slips and multi-path effects along with improvement in IPWV. The signal strength and the number of observations are more in case of 3D choke ring antenna.
