Introduction

Circular RNAs (circRNAs), a novel class of non-coding RNAs, have been implicated in various diseases and are considered to play an important role in physiological and pathological processes. We aimed to profile renal circRNA in children with primary focal segmental glomerulosclerosis (FSGS) and predict the potential mechanism underlying the pathogenesis of FSGS.

Material and methods

A global circRNA expression analysis was performed in renal tissues from patients with FSGS (n=3) and controls (n=3). Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to validate the expression levels of three circRNAs in a cohort of 44 patients with FSGS, 44 age-matched healthy controls, and 15 patients with minimal change disease (MCD).

Results

A total of 152 circRNAs were differentially expressed in patients with FSGS compared with controls. Hsa_circ_0001461 and hsa_circ_0000605 were significantly increased in patients with FSGS compared with controls, as determined by qRT-PCR (p < 0.001). The receiver operating characteristic (ROC) curve areas of hsa_circ_0001461 and hsa_circ_0000605 were 0.948 and 0.934, respectively. Hsa_circ_0001461 was significantly elevated in patients with FSGS compared with those with MCD and was correlated with 24 h urinary protein in patients with FSGS (r = 0.732, p < 0.001). Bioinformatics analysis predicted mir-30a interaction with hsa_circ_0001461. Mir-30a was negatively correlated with the renal hsa_circ_0001461 level (r = -0.90, p < 0.001).

Conclusions

Hsa_circ_0001461 is identified as a novel biomarker in children with FSGS and might provide insights into the mechanism of FSGS pathogenesis.

Published: May 2021

A norma ISSAI 5300, desenvolvida pela Organização Internacional de Entidades Fiscalizadoras Superiores (INTOSAI), objetiva ser referência global sobre os fundamentos da auditoria de tecnologia da informação (TI). Assim, o trabalho analisa o cenário da fiscalização de TI nos tribunais de contas estaduais brasileiros quanto à aderência àquela norma. Para alcançar esse objetivo, identificaram-se as características estruturais e de recursos humanos, assim como os requisitos da norma com maior destaque positivo e maior destaque negativo nas unidades de fiscalização de TI dos tribunais. É uma pesquisa quantitativa que utilizou um questionário estruturado, aplicado junto a gestores e auditores dos tribunais, cujos resultados foram analisados por estatísticas descritivas. Os resultados apontaram que somente 8 (30,77%) tribunais de contas estaduais possuem um setor para auditoria de TI. O requisito com maior destaque positivo foi “escopo da auditoria de TI” e com destaque negativo foi “planejamento anual da auditoria de TI”. Conclui-se que a auditoria de TI nas cortes de contas estaduais ainda pode avançar, tanto na estruturação como na excelência do processo fiscalizatório. Trabalhos futuros podem ampliar a abrangência desta pesquisa, replicando a metodologia para investigar os mesmos requisitos da norma ISSAI 5300, aprofundando a análise em outros tribunais de contas estaduais, em tribunais de contas municipais ou, até mesmo, no tribunal de contas da união.

Authors: Lopes Neiva Aparecida Pereira , Muniz Reynaldo Maia
Published: May 2021

Este estudo foi desenvolvido a partir dos conceitos ligados à mobilidade urbana e ao transporte coletivo, tendo em vista as manifestações ocorridas em 2013 contra o aumento das tarifas, qualidade do transporte público e sua gratuidade, como consequência desses protestos, foi aprovada pela Emenda Constitucional nº 90 em 2015, a inserção do transporte na Constituição Federal, no seu artigo 6º, como novo direito social. Discussões que vieram à tona, já que o transporte coletivo é direito de todos e a responsabilidade é dos municípios. Com o objetivo de aprender e compreender os melhores instrumentos para o desenvolvimento das políticas públicas tornou-se relevante descrever e analisar como foi o processo de implantação do transporte público gratuito no município de Monte Carmelo, MG, que foi pioneira no país. Para tanto, adotou-se o modelo do ciclo de políticas públicas de Jann e Wegrich (2007). A metodologia utilizada na pesquisa foi estudo de caso. Pelos resultados, conclui-se que não se pode generalizar uma política pública. Cada cidade tem suas características, necessidades e condições econômicas. Monte Carmelo no período da implantação desse sistema de transporte, possuía um polo industrial cerâmico que gerava impostos, sendo, assim, possível a prefeitura arcar com esse ônus.
Abertura de créditos adicionais: estudo sob a ótica da teoria da escolha pública
Authors: Carlos Filho Francisco de Assis
Published: May 2021

No intuito de testar a teoria da escolha pública, o objetivo geral da presente pesquisa foi relacionar se o vínculo partidário dos prefeitos dos municípios paraibanos com a manipulação do orçamento no setor público, através da anulação de créditos adicionais. A amostra foi constituída por todos 223 municipios do estado da Paraíba. Os anos analisados foram 2017 e 2018. Os principais resultados foram de que houve aumento significativo nos orçamentos das prefeituras paraibanas de 2017 para 2018. Por outro lado, em média 25,9% em 2017 e 22,5% em 2018 do que foi planejado foi anulado. O teste de wilcoxon demonstrou que essa diminuição de anulação nos orçamentos das prefeituras de 2017 para 2018 foi estatisticamente significativa. O teste de  Kruskal-Wallis indicou que não houve diferença estatística significativa entre os partidos políticos em relação as anulações do orçamento nem em 2017 e nem em 2018. Dessa forma não foi aceita a hipótese proposta nessa pesquisa, em que o vinculo partidário dos prefeitos dos municípios paraibanos difere em relação a manipulação do orçamento no setor público. Esse resultado encontra amparo nos pressupostos da teoria da escolha pública. Variáveis como ano e mandato eleitoral seriam interessantes de serem estudadas no contexto dessa pesquisa.

Plants are utilized as traditional medicines since time immemorial. However, the dilemma of losing this knowledge is real because of poor documentation evidenced by the relatively few studies conducted coupled with rapid urbanization especially in the Philippines. It is imperative for ethnomedicinal knowledge especially of the M’ranao tribe in Baloi, Lanao del Norte to be conserved , hence this study. Ethnomedicinal data were collected from semi-structured interviews of 30 informants and analyzed qualitatively and quantitatively. Moreover, transect walk was performed to locate the frequently used medicinal plants. This study documented seventy eight (78) species of medicinal plants belonging to 36 families used for the treatment of various ailments belonging to 14 out of 16 human disease categories. The most important medicinal plant with a Use Value (UV) of 0.43 is Mingeyak (Salvia plebeian). There were fifty five (55) floral species found to have 100% Fidelity Level (FL) value. An Informant Concensus Factor (ICF) of 1.00 for disease Category 2, Category 3, and Category 16 indicates that there was a high degree of agreement among informants on how to treat cancer, anemia, and intestinal toxicity respectively. Leaves (63%) were the most frequently used plant part and decoction (41%) was the most common way of preparation. Internal application (77%) was the most recurrent way of plant administration to the ailing body. Herbs (47%) as medicine were the most frequently used plant habit. Qualitative investigation resulted to the identification of M’ranao traditional beliefs and practices in utilizing medicinal plants which include the time of collection, the number of plant organ collected (e.g. pito-pito) and the ways of conserving herbal plants for continuing sustainability. This study further revealed that the M’ranao tribe of Baloi has a rich floral resources use as medicines which could be further investigated for pharmacological properties to improve health care for various illnesses.

Vermi plays an important role in improving soil fertility and structure. This study was conducted to find out the perceptions of vermi raisers on different vermicomposting practices adopted in Zamboanga del Sur, Philippines. The researchers utilized the descriptive method in gathering the necessary data. Results revealed that the combination of 60% rice straw, 5% kakawate, and 35% manure is the most preferred feeding materials. The respondents also revealed that the 5% inclusion rate of jackfruit, banana, and pineapple peelings in the bedding materials increases the vermi population as compared to pure rice straw, kakawate, and manure. The higher cost of inputs and labor and pest invasion are the two most encountered problems. Covering the bed with canvass or galvanized iron, follow the correct procedure in the pre-decomposition process, and seek assistance from the agriculturists are the three most effective practiced solutions. The findings showed that the population of vermi can be doubled with the inclusion of jackfruit, banana and pineapple peelings in the substrate. Moreover, the harvest time is reduced due to higher consumption level. Vermicomposting is very necessary to answer the increasing demand for organic fertilizer amidst climate change.

RESULTS OF STUDY OF THE HYPOGLOSSAL NERVE FUNCTIONS IN PATIENTS AFTER HYPOGLOSSAL-FACIAL ANASTOMOSIS
Authors: Bobrov Andrey , Borysenko Oleg , Mischanchuk Nina , Papp Alexandr
Published: May 2021

Hypoglossal-facial anastomosis is a common method of restoring and/or replacing lost facial nerve function. At the same time, there are works that compare functional disorders of the XII pair of cranial nerves that arise in patients with various types of hypoglossal-facial anastomosis, which, in turn, indicates the rather great importance of this problem, as well as the need for further research. There are several modifications of the hypoglossal-facial anastomosis, which differ significantly, including the effect on the function of the tongue muscles. An important instrumental method for studying the function of the hypoglossal nerve is electromyography, namely, the determination of the total evoked potentials of the tongue muscles. In order to study complications in the form of dysfunction of the tongue muscles due to hypoglossal-facial anastomosis, a comparative analysis of the data of the tongue electromyography in patients after performing these interventions was carried out. Materials and methods. The study included 55 patients with chronic suppurative otitis media, with tumors of the cerebello-pontine angle (acoustic and vestibular schwannomas, tumors of the jugular glomus) complicated by a lesion of the facial nerve. In the main group of patients (20 patients), the original technique of the modified hypoglossal-facial anastomosis was used to restore the facial nerve function. Patients (n=35) in the control group underwent a classic hypoglossal-facial anastomosis. Results. As can be seen from the above data, when comparing the tongue muscles contraction amplitude 3, 6 and 12 months after the formation of the hypoglossal-facial anastomosis, a statistically significant decrease in this indicator is observed on the side of performing the hypoglossal-facial anastomosis in comparison with the intact side at all stages of the study (p <0.05) (p <0.05) (p <0.01), respectively. When comparing the indicators of the total muscle response in patients after using the modified and classical methods of XII-VII anastomosis, there was a statistically significant increase in the compound muscle response of the tongue in the main group - by an average of 10.94% (p <0.05). Conclusion. Performing hypoglossal-facial anastomosis leads to gross dysfunction of the hypoglossal nerve on the side of the intervention, manifested in the form of a significant decrease in the amplitude of muscle contraction according to electromyography of the tongue. The use of the modified technique of XII-VII anastomosis provided the restoration of the total muscle potential of the tongue by 8.82% after 3 months, by 8.7% – after 6 months. and by 15.38% – after 12 months after surgery in comparison with the group where the classic hypoglossal-facial anastomosis was performed.

Authors: Vengrzhinovskaya Oksana , Bondarenko Irina
Published: May 2021

Vitamin D deficiency occurs in 30-50% of the world's population [1]. Vitamin D deficiency increases in proportion to distance from the equator, which explains the increased filtration of UV rays. [2]. It causes rickets, osteoporosis, osteomalacia, but also cardiovascular disease. The Russian and foreign studies presented in this review indicate that moderate and severe vitamin D deficiency is a risk factor for the development of cardiovascular diseases. [3].A decrease in vitamin D levels is a risk factor for cardiovascular pathology: arterial hypertension (AH), dyslipidemia, diabetes mellitus (DM), myocardial fibrosis and a predictor of adverse cardiovascular events - strokes and heart attacks. Vitamin D has a vasoprotective effect, reducing endothelial dysfunction, has a positive effect on blood pressure, reduces the risk of left ventricular hypertrophy and atherosclerosis, slows down vascular remodeling and myocardial fibrosis, reduces insulin resistance, and affects the course of inflammatory processes [4].

Evolución del uso de las TIC por parte de los adolescentes en los últimos años: luces y sombras
Authors: Plaza de la Hoz Jesús
Published: May 2021

Abstract. INTRODUCCIÓN. Estudios recientes muestran que el uso de las tecnologías de la información y la comunicación (TIC) se generaliza entre los adolescentes y que persisten los inconvenientes derivados; de ahí, el interés por la evolución de esta relación jóvenes-tecnologías. MÉTODO. Este artículo compara resultados obtenidos en 2013 con un cuestionario cumplimentado por una muestra representativa (1.032 estudiantes de ESO) con otra más reducida (235) de similar alumnado tomada en 2019. El objetivo es observar los cambios sobre el uso de Internet, su influjo en el rendimiento académico y la vulnerabilidad de los jóvenes frente a las TIC. Para la comparativa se usa el programa de tratamiento de datos SPSS, aunque con un alcance exploratorio. RESULTADOS. Se observa una disminución tanto de efectos positivos como negativos; se constata también un uso prudente de la red, pero un mayor porcentaje de los que sienten amenazas. Además, los afectados sufren en solitario sus problemas en mayor grado. DISCUSIÓN. Se confirma la normalización del uso de TIC advertido en estudios recientes, junto con efectos negativos diversos. Ante esta doble tendencia, conviene seguir empoderando a los adolescentes en usar responsablemente las TIC, de modo que se normalice también la petición de ayuda, especialmente por parte de los afectados más negativamente.

Abstract. Carbonyl Sulphide (COS), a trace gas showing striking similarity to CO2 in terms of biochemical diffusion pathway into leaves, has been recognized as a promising indicator of the plant gross primary production (GPP), the amount of carbon dioxide that is absorbed through photosynthesis by terrestrial ecosystems. However, large uncertainties about the other components of its atmospheric budget prevent us from directly relating the atmospheric COS measurements to GPP. The largest uncertainty comes from the closure of its atmospheric budget, with a source component missing. Here, we explore the benefit of assimilating both COS and CO2 measurements into the LMDz atmospheric transport model to obtain consistent information on GPP, plant respiration and COS budget. To this end, we develop an analytical inverse system that optimizes biospheric fluxes for the 15 plant functional types (PFTs) defined in the ORCHIDEE global land surface model. Plant uptake of COS is parameterized as a linear function of GPP of the leaf relative uptake (LRU), which is the ratio of COS to CO2 deposition velocities in plants. A possible scenario for the period 2008–2019 leads to a global biospheric sink of 800 GgS.yr−1, with higher absorption in the high latitudes and higher oceanic emissions between 400 and 600 GgS.yr−1 most of which is located in the tropics. As for the CO2 budget, the inverse system increases GPP in the high latitudes by a few GtC.yr−1 without modifying the respiration compared to the ORCHIDEE fluxes used as a prior. In contrast, in the tropics the system tends to weaken both respiration and GPP. The optimized components of the COS and CO2 have been evaluated against independent measurements over Northern America, the Pacific Ocean, at three sites in Japan and at one site in France. Overall, the posterior COS concentrations are in better agreement with the COS retrievals at 250 hPa from the MIPAS satellite and with airborne measurements made over North America and the Pacific Ocean. The system seems to have rightly corrected the underestimated GPP over the high latitudes. However, the change in seasonality of GPP in the tropics disagrees with Solar Induced Fluorescence (SIF) data. The decline in biospheric sink in the Amazon driven by the inversion also disagrees with MIPAS COS retrievals at 250 hPa, highlighting the lack of observational constraints in this region. Moreover, the comparison with the surface measurements in Japan and France suggests misplaced sources in the prior anthropogenic inventory, emphasizing the need for an improved inventory to better partition oceanic and continental sources in Asia and Europe.

Abstract. The term Open-Air Factor (OAF) was coined following microbiological research in the 1960s and 1970s which established that rural air had powerful germicidal properties and attributed this to Criegee intermediates formed in the reaction of ozone with alkenes. We have re-evaluated those early experiments applying the current state of knowledge of ozone-alkene reactions. Contrary to previous speculation, neither Criegee intermediates, nor the HO radicals formed in their decomposition, are directly responsible for the germicidal activity attributed to the OAF. We identify other potential candidates, which are formed in ozone-alkene reactions and have known (and likely) germicidal properties, but the compounds responsible for the OAF remain a mystery. There has been very little research into the OAF since the 1970s and this effect seems to have been largely forgotten. In this letter we remind the community of the germicidal open-air factor. Given the current global pandemic spread by an airborne pathogen, understanding the natural germicidal effects of ambient air, solving the mystery of the open-air factor, and determining how this effect can be used to improve human welfare should be a high priority for the atmospheric science community.

Abstract. Terrestrial mud volcanoes (MVs) represent the surface expression of conduits tapping fluid and gas reservoirs in the deep subsurface. Such plumbing channels provide a direct, effective means to extract deep microbial communities fueled by geologically produced gases and fluids. The drivers accounting for the diversity and composition of these MV microbial communities distributed over a wide geographic range remain elusive. This study characterized microbial communities of 15 terrestrial MVs across a distance of ~10,000 km of the Eurasian continent to test the validity of distance control and physiochemical factors in explaining biogeographic patterns. Our analyses yielded diverse community compositions with a total of 28,928 amplicon sequence variances taxonomically assigned to 73 phyla. Although no cosmopolitan member was found, community variance between geographic locations was higher than within sites, generating a slope of distance–decay relationship exceeding those for marine seeps and MVs, and seawater columns. For comparison, physiochemical parameters explained 12 % of community variance, and specific geochemical parameters were correlated with specific taxa. Overall, the apparent lack of fluid exchange renders terrestrial MVs a patchy habitat with microbiome comprising specific colonists that are highly adapted to the local environmental context and restricted in terms of dispersal capability.

Abstract. High quality quantitative maps of seabed sedimentary physical and geochemical properties have numerous research and conservation applications, including habitat and ecosystem modelling, marine spatial planning and ecosystem service mapping. However, such maps are lacking for many ecologically and economically important marine areas. Using legacy data supplemented by measurements from recent benthic surveys, modelled hydrodynamic variables and high resolution bathymetry, quantitative maps for the top 10 cm of seabed sediment were generated via a combination of statistical and machine-learning techniques for the Firth of Clyde, a semi-enclosed coastal sea on the west coast of Scotland. The maps include sediment fractions of mud, sand and gravel, whole-sediment median grain size, sediment permeability and porosity, rates of natural seabed abrasion, and sediment particulate organic carbon and nitrogen content. Properties were mapped over an unstructured grid, so that very high resolutions were achieved close to the coastlines, where sediments may be expected to be spatially heterogeneous. Overall, the maps reveal extensive areas of very low sediment permeability coupled with low rates of natural seabed disturbance. Moreover, muddy sediments in the inner Firth of Clyde, Inchmarnock Water and the sea lochs are enriched in organic carbon and nitrogen relative to the sediments of the outer Firth of Clyde. As a demonstration of the value of these maps, the standing stock of organic carbon and nitrogen in the surficial sediments of the Clyde was calculated. The Clyde stores 3.42 and 0.33 million tonnes of organic carbon and nitrogen in the top 10 cm of seabed sediment, respectively, substantially contributing to Scotland’s coastal and shelf blue carbon stocks.

Characteristics of droughts in Argentina's core crop region

Abstract. This study advances the understanding and impacts of dry episodes on wheat, corn, and soybean yields over Argentina's core crop region. The production of these major crops is intense and is the main contribution to the country's gross domestic product. Our analysis focuses on the droughts' properties, including their magnitude, frequency at different timescales, duration, and severity. We analyzed 40 years of precipitation and soil moisture anomalies and their corresponding nonparametric standardized indices at timescales of 1, 3, and 6 months. The climate variables were complemented with 40 years of the crops' yield data. The percentage of drought occurrence in northeastern Argentina ranges between 12 % and 18 %, with the larger values located towards the core crop region's eastern–northeastern sector. An analysis of drought duration suggests that most cases tend to occur for periods shorter than 3 months, while a few can extend up to 1 year, and even fewer can last longer. More importantly, regardless of the duration, droughts have larger impacts during the crops' critical growth period. Corn and soybean have their critical growth periods during summer and are more sensitive to precipitation and soil moisture deficits than wheat, which has its critical growth period during spring. Quantification of the relation between the droughts' indicators during the crops' critical periods and detrended annual crop yields was performed. Large drought severity values during the crop-sensitive months result in significant crop yield losses. Results suggest that shorter-scale indicators during sensitive periods are more appropriate for predicting crop yield losses than the longer-scale indicators. This new approach can be helpful for regional decision-making systems that support planning by water managers and agricultural stakeholders.
Global riverine flood risk – how do hydrogeomorphic floodplain maps compare to flood hazard maps?

Published: May 2021

Abstract. Riverine flood risk studies require the identification of areas prone to potential flooding. This process can be based on either (hydrologically-derived) flood hazard maps or (topography-based) hydrogeomorphic floodplain maps. In this paper, we derive and compare riverine flood exposure from three global products: a hydrogeomorphic floodplain map (GFPLAIN) and two flood hazard maps (JRC and GAR). We find an average spatial agreement between these maps of around 30% at river basin level on a global scale. This agreement is highly variable across model combinations and geographic conditions, influenced by climatic humidity, river volume, topography, and coastal proximity. Contrary to expectations, the agreement between the two flood hazard maps is lower compared to their agreement with the hydrogeomorphic floodplain map. We also map riverine flood exposure for 26 countries across the Global South, by intersecting these maps with three human population maps (GHS, HRSL and WorldPop). The findings of this study indicate that hydrogeomorphic floodplain maps can be a valuable way of producing high-resolution maps of flood-prone zones to support riverine flood risk studies, but caution should be taken in regions that are dry, steep, very flat or near the coast.
Spatiotemporal distribution of seasonal snow water equivalent in High-Mountain Asia from an 18-year Landsat-MODIS era snow reanalysis dataset

Abstract. Seasonal snowpack is a key water resource and plays an important role in regional climate. However, how seasonal snow mass is distributed over space and time is not fully understood. This is due to the difficulties in estimation from remote sensing or ground measurements, especially over mountainous areas, such as High-Mountain Asia (HMA). In this paper we examined the spatiotemporal distribution of seasonal snow water equivalent (SWE) over HMA using a newly developed snow reanalysis dataset. The dataset was derived using a data assimilation method constrained by satellite observed snow data, spanning across 18 water years (2000–2017), at a high spatial (~500 m) and temporal (daily) resolution. Based on the results, the climatology of seasonal SWE volume is quantified as ~163 km3 over the entire HMA region, with 66 % of that in the northwestern watersheds (e.g. Indus, Amu Darya and Syr Darya). An elevational analysis shows that seasonal SWE volume peaks at mid-elevations (~3500 m). This work should help better understanding the snowpack climatology and variability over HMA, providing insights for future studies in assessing seasonal snow and its contribution to the regional water cycle and climate.
