Authors: Pang Shimei , Lin Ziqiu , Zhang Yuming , Zhang Wenping , Alansary Nasser , Mishra Sandhya , Bhatt Pankaj , Chen Shaohua
Published: September 2020

Imidacloprid is a neonicotinoid insecticide that has been widely used to control insect pests in agricultural fields for decades. It shows insecticidal activity mainly by blocking the normal conduction of the central nervous system in insects. However, in recent years, imidacloprid has been reported to be an emerging contaminant in all parts of the world, and has different toxic effects on a variety of non-target organisms, including human beings, due to its large-scale use. Hence, the removal of imidacloprid from the ecosystem has received widespread attention. Different remediation approaches have been studied to eliminate imidacloprid residues from the environment, such as oxidation, hydrolysis, adsorption, ultrasound, illumination, and biodegradation. In nature, microbial degradation is one of the most important processes controlling the fate of and transformation from imidacloprid use, and from an environmental point of view, it is the most promising means, as it is the most effective, least hazardous, and most environmentally friendly. To date, several imidacloprid-degrading microbes, including Bacillus, Pseudoxanthomonas, Mycobacterium, Rhizobium, Rhodococcus, and Stenotrophomonas, have been characterized for biodegradation. In addition, previous studies have found that many insects and microorganisms have developed resistance genes to and degradation enzymes of imidacloprid. Furthermore, the metabolites and degradation pathways of imidacloprid have been reported. However, reviews of the toxicity and degradation mechanisms of imidacloprid are rare. In this review, the toxicity and degradation mechanisms of imidacloprid are summarized in order to provide a theoretical and practical basis for the remediation of imidacloprid-contaminated environments.

Authors: Tillmann Urban , Krock Bernd , Wietkamp Stephan , Beran Alfred
Published: September 2020

Species of the dinophyte genus Alexandrium are widely distributed and are notorious bloom formers and producers of various potent phycotoxins. The species Alexandrium taylorii is known to form recurrent and dense blooms in the Mediterranean, but its toxin production potential is poorly studied. Here we investigated toxin production potential of a Mediterranean A. taylorii clonal strain by combining state-of-the-art screening for various toxins known to be produced within Alexandrium with a sound morphological and molecular designation of the studied strain. As shown by a detailed thecal plate analysis, morphology of the A. taylorii strain AY7T from the Adriatic Sea conformed with the original species description. Moreover, newly obtained Large Subunit (LSU) and Internal Transcribed Spacers (ITS) rDNA sequences perfectly matched with the majority of other Mediterranean A. taylorii strains from the databases. Based on both ion pair chromatography coupled to post-column derivatization and fluorescence detection (LC-FLD) and liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) analysis it is shown that A. taylorii AY7T does not produce paralytic shellfish toxins (PST) above a detection limit of ca. 1 fg cell−1, and also lacks any traces of spirolides and gymnodimines. The strain caused cell lysis of protistan species due to poorly characterized lytic compounds, with a density of 185 cells mL−1 causing 50% cell lysis of cryptophyte bioassay target cells (EC50). As shown here for the first time A. taylorii AY7T produced goniodomin A (GDA) at a cellular level of 11.7 pg cell−1. This first report of goniodomin (GD) production of A. taylorii supports the close evolutionary relationship of A. taylorii to other identified GD-producing Alexandrium species. As GD have been causatively linked to fish kills, future studies of Mediterranean A. taylorii blooms should include analysis of GD and should draw attention to potential links to fish kills or other environmental damage.
Merkel Cell Polyomavirus in Merkel Cell Carcinoma: Integration Sites and Involvement of the KMT2D Tumor Suppressor Gene
Authors: Arora Reety , Choi Jae Eun , Harms Paul W. , Chandrani Pratik
Published: September 2020

Merkel cell carcinoma (MCC) is an uncommon, lethal cancer of the skin caused by either Merkel cell polyomavirus (MCPyV) or UV-linked mutations. MCPyV is found integrated into MCC tumor genomes, accompanied by truncation mutations that render the MCPyV large T antigen replication incompetent. We used the open access HPV Detector/Cancer-virus Detector tool to determine MCPyV integration sites in whole-exome sequencing data from five MCC cases, thereby adding to the limited published MCPyV integration site junction data. We also systematically reviewed published data on integration for MCPyV in the human genome, presenting a collation of 123 MCC cases and their linked chromosomal sites. We confirmed that there were no highly recurrent specific sites of integration. We found that chromosome 5 was most frequently involved in MCPyV integration and that integration sites were significantly enriched for genes with binding sites for oncogenic transcription factors such as LEF1 and ZEB1, suggesting the possibility of increased open chromatin in these gene sets. Additionally, in one case we found, for the first time, integration involving the tumor suppressor gene KMT2D, adding to previous reports of rare MCPyV integration into host tumor suppressor genes in MCC.
Hybrid Pumped Hydro Storage Energy Solutions towards Wind and PV Integration: Improvement on Flexibility, Reliability and Energy Costs
Authors: Simão Mariana , Ramos Helena
Published: September 2020

This study presents a technique based on a multi-criteria evaluation, for a sustainable technical solution based on renewable sources integration. It explores the combined production of hydro, solar and wind, for the best challenge of energy storage flexibility, reliability and sustainability. Mathematical simulations of hybrid solutions are developed together with different operating principles and restrictions. An electrical generating system composed primarily by wind and solar technologies, with pumped-storage hydropower schemes, is defined, predicting how much renewable power and storage capacity should be installed to satisfy renewables-only generation solutions. The three sources were combined considering different pump/turbine (P/T) capacities of 2, 4 and 6 MW, wind and PV solar powers of 4–5 MW and 0.54–1.60 MW, respectively and different reservoir volume capacities. The chosen hybrid hydro-wind and PV solar power solution, with installed capacities of 4, 5 and 0.54 MW, respectively, of integrated pumped storage and a reservoir volume of 378,000 m3, ensures 72% annual consumption satisfaction offering the best technical alternative at the lowest cost, with less return on the investment. The results demonstrate that technically the pumped hydro storage with wind and PV is an ideal solution to achieve energy autonomy and to increase its flexibility and reliability.
Reach-Scale Model of Aquatic Vegetation Quantifies N Fate in a Bedrock-Controlled Karst Agroecosystem Stream
Authors: Bunnell Nolan L. , Ford William I. , Fogle Alex W. , Taraba Joseph
Published: September 2020

In-stream fate of nutrients in karst agroecosystems remains poorly understood. The significance of these streams is recognized given spring/surface water confluences have been identified as hotspots for biogeochemical transformations. In slow-moving streams high in dissolved inorganic nutrients, benthic and floating aquatic macrophytes are recognized to proliferate and drastically impact nutrient fate; however, models that quantify coupled interactions between these pools are limited. We present a reach-scale modeling framework of nitrogen dynamics in bedrock-controlled streams that accounts for coupled interactions between hydrology, hydraulics, and biotic dynamics and is validated using a multi-year, biweekly dataset. A fluvial N budget with uncertainty was developed to quantify transformation dynamics for the dissolved inorganic nitrogen (DIN) pool using a GLUE-like modeling framework, and scenario analyses were run to test for model function over variable environmental conditions. Results from a 10,000 run uncertainty analysis yielded 195 acceptable parameter sets for the calibration period (2000–2002), 47 of which were acceptable for the validation period (2003) (Nash-Sutcliffe Efficiency (NSE) > 0.65; percent bias (PBIAS) < ±15), with significantly different posterior parameter spaces for parameters including denitrification coefficients and duckweed growth factors. The posterior solution space yielded model runs with differing biomass controls on DIN, including both algae and duckweed, but suggested duckweed denitrifies at a rate that would place the bedrock agroecosystem stream on the high-end of rates reported in the literature, contradicting the existing paradigm about bedrock streams. We discuss broader implications for watershed-scale water quality modeling and implementation strategies of management practices for karst agroecosystems, particularly with respect to stream restoration.
Slope Erosion and Hydraulics during Thawing of the Sand-Covered Loess Plateau

Published: September 2020

Seasonal freeze-thaw processes have led to severe soil erosion globally. Slopes are particularly susceptible to changes in runoff, it can be useful to study soil erosion mechanisms. We conducted meltwater flow laboratory experiments to quantify the temporal and spatial distribution of hydraulic parameters on sandy slopes in relation to runoff and sediment yield under constant flow, different soil conditions (unfrozen slope: US; frozen slope: FS), and variable sand thickness. The results showed that sand can prolong initial runoff time, and US and FS have significantly different initial runoff times. There was a significant linear relationship between the cumulative runoff and the cumulative sediment yield. Additionally, hydrodynamic parameters of US and FS varied with time and spatially, as the distance between US and FS is linearly related to the top of the slope. We found that the main runoff flow pattern was composed of laminar flow and supercritical flow. There was a significant linear relationship between flow velocity and hydraulic parameters. The flow velocity is the best hydraulic parameter to simulate the trend of slope erosion process. This study can provide a scientific basis for a model of slope erosion during thawing for the Loess Plateau.
Non-traditional feed and probiotics for rearing of goslings
Authors: Lushnikov N. , Loshkomoynikov I.
Published: September 2020

Currently, considerable interest is caused by the study of the effect of various feed additives on the productive performance of animals. The ban on the use of antibiotics to stimulate poultry growth in many European countries has increased the interest of researchers and practitioners in the use of probiotics. It is important to study the use of non-traditional feed in animal husbandry. Thus, waste processing of rapeseed (presscake, meal) is the most important sources of essential amino acids (lysine, methionine, tryptophan, etc.), essential fatty acids (linoleic, linolenic, arachidonic, oleic, etc.). The importance of rapeseed seeds and products of its processing has increased after the breeding of varieties with a low content of erucic acid and glucosinolates. The purpose of the research was to study the use of non-traditional feed and probiotics in the rearing of goslings to obtain full-fl edged products when they are grown up to 4 months of age. The possibility of replacing sunflower presscake with rapeseed presscake of Siberian selection and partial replacement of full-fat soy with rapeseed oil has been carried out. It has been found that the treatment of goslings after birth with probiotics “Prolam” and “Monosporin” and their use in feeding the goslings had a positive effect on their growth and development. With an increase in production costs and an increase in the cost of feed, the prime cost of 1 kg of live weight gain has decreased when processing and feeding probiotic “Prolam” by 17,9 %, “Monosporin” by 15,4 %. It has been obtained profits on 1 head more from the use of probiotics by 29,8 and 35 Rubles, respectively, in comparison with the control group. The level of profitability when using probiotics in the 1st experimental group has increased by 29,7 %, in the 2nd group by 24,7 %. The weight of the semi-eviscerated carcass was higher in the experimental groups receiving rapeseed presscake and rapeseed presscake in combination with rapeseed oil, and exceeded the weight of the carcasses of the control group by 286,13 and 388,48 g, respectively. The mass of eviscerated carcasses was also higher in the experimental groups.
Analysis of compliance of box sizes to comfortable housing of highly productive cows
Authors: Turlyun V.
Published: September 2020

The analysis of some herds of imported cattle under the conditions of Russian farms had been shown that the genetic potential of imported cattle in many farms has being realized only by 57 %, with the output of up to 50 % of the cattle during the first 2 years. The reason for this is the discrepancy between the conditions of the biological needs of animals. In this regard, the study of factors that affect the provision of comfortable conditions for animals plays an important role. This is especially true for Holstein animals, which are more susceptible to various diseases. In accordance with the technological solutions used in modern large complexes, the loose housing method of maintenance is mainly used. This method allows the animal to move freely, providing access to the consumption of water and feed, as well as timely rest. This determines the importance of the requirements for the size of the boxes for the rest of animals, which should ensure dryness and cleanliness in the process of resting cows, prevent damage to animals, as well as the ability of other animals to displace each other. The crossbars should not interfere with the free movement of the cow in the process of lowering to the floor and getting up due to their flexibility. The dimensions of the boxes should be made taking into account the measurements of the animals’ torso, as well as the amplitude of movement in the process of lowering and rising. The purpose of the research was to study the size of boxes and their compliance with the biological needs of highly productive imported cattle. An analysis of the compliance of conditions for housing highly productive cattle of Canadian and Australian origin with their biological needs under the conditions of a mega farm has been presented in the paper. Calculation on the basis of measurements of animals has been shown that animals of the Canadian selection require boxes with a total length of at least 279 cm, Australian – 271 cm. The difference with the required width of the box has been also established. For the group of cows of Canadian selection it should be at least 120 cm, for the Australian – 114 cm. Research results have been shown that the discrepancy in the design of boxes for comfortable rest of animals is a deterrent to the realization of their genetic productive potential.
The history and distribution of the bulbil-bearing Ficaria verna subsp. verna (Ranunculaceae) in Britain
Authors: Braithwaite Michael
Published: September 2020

The distributions of the subspecies of Ficaria verna Huds. are under-recorded in Britain, but published county Floras indicate that subsp. verna is an introduction in some areas and is increasing in many areas. This evidence is examined and a hypothesis to account for the observed patterns is tested against an analogy with Allium paradoxum (M. Bieb.) G. Don in Berwickshire where the author has personally observed colonisation over forty years. The results suggest a link between the recent increase in Ficaria verna subsp. verna and the nineteenth century expansion of the horticultural trade. Earlier waves of colonisation are suspected but not substantiated.

O uso de plantas medicinais para fins terapêuticos é uma prática utilizada desde os primórdios da humanidade até os dias atuais. O Cerrado é considerado um hotspot de biodiversidade. De toda a diversidade florística existente no bioma há aproximadamente 220 espécies medicinais que são utilizadas diretamente pelo homem. O objetivo do trabalho foi avaliar a percepção de moradores da Cidade de Goiás sobre o uso de plantas medicinais e os impactos ambientais sobre a vegetação do Cerrado. Foram feitas 40 entrevistas com moradores do Município através da abordagem direta com a utilização de um questionário semiestruturado, as perguntas foram relativas ao uso de plantas medicinais e a percepção dos impactos ambientais sobre a vegetação da região. As espécies mais citadas foram Lippia alba, Stryphnodendron adstringens, Lychnophora spp. e Vernonanthura polyanthes, a parte da planta mais utilizada é a folha, seguida da casca. Grande parte das pessoas identificam o Cerrado pelas plantas, a maioria citou Anacardium spp. e Caryocar brasiliense, 92% delas afirmaram perceber diminuição das plantas medicinais com o passar dos anos, o desmatamento foi apontado como a principal causa, seguido de extrativismo predatório. O uso de plantas medicinais na região da Cidade de Goiás é uma prática comum e importante para a população, no entanto, os entrevistados relataram que com o passar do tempo a vegetação tem diminuído devido a ação do homem. Desse modo torna-se necessário medidas de conscientização e proteção do Cerrado para a manutenção da biodiversidade e da cultura popular relacionada ao uso das plantas medicinais.

Вивчено особливості нейропротективної тактики хірургічного лікування атеросклеротичного стенозу внутрішньої сонної артерії. В аналіз включено 108 пацієнтів з поєднаним атеросклеротичним ураженням церебральних і каротидних артерій, яким була зроблена оцінка резервних можливостей головного мозку. На підставі результатів, які були отримані під час проведення ішемічних проб, пацієнтів розподілили на дві групи. До 1-ї групи увійшло 68 осіб, яким була виконана каротидна ендартеректомія без використання тимчасового шунта, 2-гу групу склали 40 пацієнтів, яким дана операція виконувалася з використанням ТШ (тимчасового шунта). Рішення про використання шунта приймали за сукупністю показників ретроградного тиску, неврологічного дефіциту, кровотоку по середній мозковій артерії. У пацієнтів з оклюзією сонних артерій з контрлатеральної сторони використання ТШ показано незалежно від показників оксиметрії, ретроградного тиску, швидкості по середній мозковій артерії. При поєднаному атеросклеротичному ураженні сонних і церебральних артерій тактика хірургічного лікування повинна ґрунтуватися на оцінці функціональних резервів головного мозку. Результати проведеної проби гіпоксії слугували додатковим критерієм щодо рішення про накладення внутрішнього шунта (ВШ). Це дозволяє уникнути додаткових можливих ускладнень в ранньому післяопераційному періоді. Розімкнене Вілізієве коло не вимагає використання тимчасового шунта у 32 випадках

Abstrak. Survival analysis merupakan salah satu metode statistika yang sering digunakan untuk menganalisis data yang berhubungan dengan waktu kejadian. Waktu survival didefiniskan sebagai waktu bertahan suatu objek pada awal pengamatan hingga terjadinya suatu peristiwa (event or end-event). Salah satu tujuan dari analisis survival adalah mengetahui hubungan antara waktu survival dengan variabel independen yang diduga mempengaruhi waktu survival-nya. Hubungan antara waktu survival dan variabel independen dapat dimodelkan dengan menggunakan regresi cox. Dalam penggunaan model regresi cox proportional hazard diasumsikan bahwa variabel independen memenuhi asumsi proportional hazard. Salah satu pendekatan yang digunakan jika asumsi proportional hazard tidak memenuhi adalah pendekatan model regresi extended cox. Data yang digunakan dalam penelitian ini adalah data pasien kanker serviks di RSUD Kota Makassar Tahun 2017-2018. Data kanker serviks memiliki karakteristik yang memungkinkan untuk dilakukan analisis dengan menggunakan regresi extended cox. Adapun hasil analisis yang diperoleh variabel phlebitis tidak memenuhi asumsi proportional hazard, hal ini mengindikasikan bahwa variabel phlebitis bergantung pada waktu. Variabel yang signifikan mempengaruhi laju kesembuhan penderita kanker serviks adalah jenis pengobatan operasi dan phlebitis, dimana jenis pengobatan operasi memiliki probabilitas kesembuhan 13,90 kali lebih besar dibandingkan dengan pasien yang menggunakan jenis pengobatan lain. Sedangkan penderita kanker kanker serviks mengalami kejadian phebitis memiliki probablitias kesembuhan 0,39 kali lebih kecil dibandingkan dengan pasien yang tidak mengalami kejadian phlebitis.Keywords: Survival Analysis, Regresi Cox, Regresi Extended Cox, Kanker serviks.

Published: September 2020

Tivemos como objetivo investigar como os coveiros lidam com aspectos míticos e numinosos referentes ao fenômeno da morte no mundo da vida cotidiana e ao espaço do cemitério. Realizamos entrevistas semiestruturadas com coveiros atuantes no Cemitério do Bonfim, em Belo Horizonte, Minas Gerais. Foram utilizadas entrevistas de três sujeitos, e para a análise fenomenológica seguimos as diretrizes metodológicas de van der Leeuw. Foram encontrados quatro núcleos de sentido de experiências de coveiros diante do numinoso: a) o aspecto assombroso do cemitério; b) atravessamento da fronteira de “lá” para “cá”; c) a passagem do aquém para o além; e d) a manifestação da fronteira entre o além e o aquém. Concluímos que, ao lidarem com a fronteira porosa e flexível que separa o familiar do estranho, cada coveiro estabelece a distância e a relação com essa fronteira e com os aspectos míticos referentes ao fenômeno da morte.

O Paradigma da Intersetorialidade nas Políticas Públicas de Esporte e Lazer
Authors: Bonalume Cláudia Regina
Published: September 2020

O presente artigo foi elaborado a partir da pesquisa Esporte e lazer na formulação de uma política pública intersetorial para a juventude: a experiência do PRONASCI, desenvolvida enquanto dissertação de mestrado da autora, na Universidade de Brasília, Programa de Pós-Graduação em Educação Física – 2010. O desafio que nos leva a construir reflexões acerca da temática da intersetorialidade parte do momento em que nos deparamos com o esporte e o lazer passando a comporem o rol das políticas sociais, ao, gradualmente, começarem a alcançar o status de direito social e, ao mesmo tempo, sendo desafiados a assumir um caráter intersetorial. Se conquistar o espaço de política pública, reconhecida como direito social, representa uma árdua tarefa, fazê-lo acontecer como proposta democrática, descentralizada, universal e intersetorial, demanda muito esforço e clareza por parte dos gestores e da população em geral.

This research was conducted to investigate the functions of modal verbs in the UN Secretary-General's remarks on climate change. Qualitative descriptive research design was employed in conducting this research. The benefits of this research are expected to contribute to the development of semantic research regarding modal verbs, and provide the understanding of the functions of modal verbs expressed in response to the climate change. The findings show that the functions of modal verbs expressed in the remarks are certainty, possibility, volition, and obligation. The speaker used the modal verb ‘will’ to express certainty, and volition, while the modal verb ‘must’, and the lexical modal ‘have to’ were used to express obligation. The speaker used the modal verb ‘can’ and the modal verb ‘could’ to express possibility. Based on the results of the research, certainty is the function that was mostly expressed in the remarks, followed by possibility, volition, and obligation. A lot of certainties expressed in the UN Secretary-General's remarks on climate change signifies that the speaker conveyed a lot of predictions or events referring to future time.

Published: September 2020

In order to support a massive number of resource-constrained Internet of Things (IoT) devices and machine-type devices, it is crucial to design future beyond 5G/6G wireless networks in an energy-efficient manner while incorporating the network extension methodologies. To this end, this letter proposes a novel two-hop hybrid active-and-passive relaying scheme to facilitate simultaneous wireless information and power transfer (SWIPT) considering both the Time-Switching (TS) and Power-Splitting (PS) receiver architectures, while dynamically modelling the involved dual-hop time-period (TP) metric. An optimization problem is formulated for the joint optimization of throughput, harvested energy, and transmit power of a SWIPT-enabled system

with the proposed hybrid scheme, and is solved using a nonlinear optimizer. Our numerical results in terms of weighted utility function show the superior performance of proposed hybrid scheme over passive repeater-only and active relay-only schemes, while also depicting their individual performance benefits over the corresponding benchmark SWIPT systems with the fixed-TP.
Primavera del periodismo en Venezuela: cooperación y democracia. Aproximación desde la ética de la razón cordial
Authors: Suárez Montoya Leonardo
Published: September 2020

El objetivo general de este texto es analizar cómo la noción de la cooperación puede entronizarse en el oficio del periodismo desde la perspectiva de la ética de la razón cordial. Se pondrán en relación dos ejemplos de periodismo colaborativo en Venezuela, que aun no teniendo como base teórica ética, se rigen por ellos. Con este artículo se aspira a generar espacios de reflexión para fortificar el êthos de la comunicación social, de las empresas informativas y del periodista, con el norte de la democracia y la justicia social. Los autores principales de esta investigación son: Patrici Calvo (2012, 2017, 2018), para hablar de la cooperación desde la ética de la razón cordial, corriente filosófica creada por Adela Cortina (2007). Se ha recurrido a la hermenéutica crítica como método de reflexión y postura para la revisión teórico-conceptual y así, poder replantear la idea del periodismo y de su ética. El periodismo puede y debe contribuir con la democracia y no limitarse a la difusión de mensajes sin ningún propósito; por otro lado, antes de hablar de cooperación, hay un valor en la profesión periodística, el celo por la noticia, anclado en el afán de la primicia y de la exclusividad; en esta reflexión se apunta a reconducir ese celo noticioso hacia la democracia. Dicho esto, los medios de comunicación y plataformas digitales enfrentan el reto de asumir el deber ético de emprender una nueva narrativa profesional, corporativa y social desde de la colaboración, la solidaridad y compasión.

Citrus fruits are among the most consumed fruits by Brazilians, being grown in practically all states. Phenotyping has been associated with non-destructive optical analysis of plant characteristics, due to the use of images. The present study had the objective of estimating the morphological characteristics of Pera Rio orange fruits (Citrus sinensis) acquired in the local trade of Alta Floresta through traditional methods and using the Tomato Analyzer softwer. Measurements were made regarding length and width with the aid of a digital caliper, fruit mass using a digital precision analytical balance, total soluble solids content (ºBrix), skin thickness and height of the endocarp. The volume was also measured using the water column displacement method (VDCA), estimated diameter values with the Tomato Analyzer program, the correlation between the volumes was performed, and regression model estimates were performed based on the SigPlot program. . It was found that there was a correlation between volume estimation by the water column displacement method (VDCA) and fruit volume using the diameter estimated by the digital image (IPV), revealing that the R2 correlation coefficient was 0.80. Through the obtained results it is possible to state that the Tomato Analyzer is efficient to evaluate the volume of orange Pera Rio fruits, being able to be indicated to characterize other citrus fruits.

This work evaluated the bioactive compounds and the antioxidant potential of honey produced by Africanized bees (Apis mellifera L.) in the state of Piauí, Brazil. The analyses show that all honeys investigatedpresented features of the pollen type Mimosa caesalpiniifolia. The content of phenolic compounds ranged from 27.65 to 97.01 mg in GAE g-1 of honey, with an average content of 62.66 ± 20.46 mgEAG g-1 of honey. The total flavonoid contents expressed in mg of quercentin/g of honey ranged from 5.43 to 13.02 mg of QE g-1, with an average of 8.33 ± 1.86 mg of QE g-1 of honey. The best performance of antioxidant activity by reducing power was EC50 of 0.15 and the lowest performance of antioxidant activity with IC50 was 1.24. The highest antioxidant activity (DPPH) ranged from 66.11 ± 0.02mg EAQ 100g-1, while the lowest activities were 9.16 and 10.88 mg EAQ 100g-1. The results show that the contents of total phenolic compounds, total flavonoids, DPPH antioxidant activity, and the pollen-reducing power from Piauí were influenced by botanical origin.
