Seedling transplanting is one of the predominant rice production systems in China. The production of hydroponically grown long‐mat rice seedlings (HLMS) is a novel seedling cultivation method that reduces labor costs and improves efficiency. There is an urgent need to explore the optimum seedling age that maximizes grain yield from HLMS. Experiments were conducted to investigate the effects of seedling age on the seedling quality, field growth characteristics and grain yield of rice grown from HLMS. The grain yield was higher for young seedlings (13 d) than for older seedlings (27 d) as a result of robust seedling quality, increased mechanical transplanting quality, slight transplanting shock, sufficient tillers and increased panicle numbers in both cultivars when grown from HLMS under normal seeding density, and there was no significant difference in grain yield between transplanted 13‐ and 20‐d‐old seedlings. Moreover, the decreased yield in Wuyunjing24 might due to the reduced number of spikelets per panicle in old seedlings. In addition, the force of root entwining was significantly enhanced with increasing seedling age for both seedling cultivation methods and cultivars, and it was significantly higher for HLMS than for conventional mat seedlings raised in soil (CMSS). In general, transplanting young seedlings (13–20 d) by the HLMS method under normal seeding density brings better plant performance and higher yield than does transplanting older seedlings; relative to CMSS, HLMS increased the flexibility of seedling age (>7 d) and operational feasibility, which can be mainly ascribed to the enhanced force of root entwining.

Core Ideas

Hydroponically grown long‐mat seedlings significantly enhanced the force of root entwining (>8 kilograms per block), enabling rice seedlings of different ages to withstand farming operations.

Relative to conventional mat seedlings raised in soil, hydroponically grown long‐mat seedlings increased the flexibility of seedling age at transplant (>7 d).

Transplanting young seedlings (13–20 d) by the hydroponically grown long‐mat seedlings method achieved higher grain yield than did transplating older seedlings (27 d) under normal seeding density.

Published: September 2019

There is a lack of information on how to determine N‐use efficiency and monitoring and diagnosing N losses in irrigated potato (Solanum tuberosumL.) production. This study was conducted to determine and validate a simple model to estimate inorganic N leaching losses (Nlosses) from gravitational water and to determine Nlossesthresholds using the soil N and canopy sensor tests. We conducted field experiments (n= 6) from 2008 to 2012 to evaluate the effects of N rates and/or managements and gravitational water on tuber yield, crop N uptake (Nuptake) and Nlosseson the cultivar Innovator in the Argentinean Pampas. The N nutrition index (NNI), normalized chlorophyll meter reading (NNI‐CM), relative chlorophyll meter reading (CMr), and relative normalized difference vegetative index (NDVIr) were determined 70 d after planting. Tuber yield, residual N, and Nlossesvaried from 40.8 to 70.3 t ha−1, 23.2 to 78.7 kg N ha−1and 6.4 to 219.4 kg N ha−1, respectively. The Nlosseswere directly associated with the amount of gravitational water in the soil profile (r2= 0.79). Threshold values of 255 kg N ha−1for N available, 1.0 for NNI, 1.03 for NNI‐CM, 0.94 for CMr and 0.98 for NDVIr were defined. We determined linear increases in Nlossesabove these thresholds (r2= 0.75, 0.35, 0.53, 0.40, and 0.46, respectively). High N rates and gravitational water increased the N losses in potato crops under irrigation. This information could be useful to adjust N fertilizer recommendation and monitoring the Nlossesin potato crops under irrigation.

Core Ideas

Information on how to monitor and diagnose N losses in irrigated potato production is lacking.

This study estimates N losses from gravitational water, soil N, and canopy sensor tests.

The aim is to predict N‐loss thresholds using soil N and canopy sensor tests.

N losses were directly associated with the amount of gravitational water in the soil profile.

Published: September 2019

Gross primary production (GPP) is a measure for crop productivity, indicating yield and expressing C exchange of agro‐ecosystems. A multitude of satellite sensors at varying spatial and spectral resolution brings a possibility to use remotely sensed data for regional and global GPP estimation. More work is still needed to develop algorithms for GPP estimation applicable to multiple, if not all, vegetation types, phenological phases, and environmental conditions. This study employed neural networks (NN), multiple linear regressions (MLR), and vegetation indices (VI) to develop algorithms for GPP estimation based solely on remotely sensed data in two crops, maize (Zea mays L.) and soybean [Glycine max (L.) Merr.], with contrasting canopy architectures, leaf structures, and photosynthetic pathways. The focus of the study was to devise algorithms not requiring re‐parameterization for different crop species. Data used in the models included in situ hyperspectral reflectance and satellite surface reflectance products. For the tested NN, MLR, and VI algorithms, the bands selected to obtain minimal errors in maize and soybean combined were mainly located in red edge and near infrared (NIR) spectral regions. For both in situ reflectance and satellite surface reflectance, a NN estimated GPP with normalized root mean square errors (NRMSE) below 14 and 18.7%, respectively, and VI using bands in red edge and NIR with NRMSE 15.6 and 20.4%, respectively. The results showed that the models based on the red edge and NIR bands may facilitate accurate assessments of crop GPP at multiple scales, from close range to satellite platforms.

Core Ideas

The models using remotely sensed data allow accurate estimation of gross primary production in two crops.

The optimal bands for gross primary production estimation in two crops were in near infrared and red edge regions.

Vegetation indices with red edge and near infrared reflectance were generic for maize and soybean.

Published: September 2019

To meet the estimated future increase in wheat (Triticum aestivum L.) demand, exploring and dissecting the genetic basis of yield‐related traits play a crucial role in wheat yield improvement. In this study, we evaluated 12 grain yield‐related traits including fruiting efficiency (FE) in a wheat panel through genome‐wide association mapping (GWAS) approach. The panel displayed large phenotypic variation for all the measured traits, FE was positively associated with grain number per spike but not related to thousand kernel weight. Interestingly, FE was mostly explained by grain number per fertile spikelet (GFS), whereas the latter was determined by spikelet weight (SW). The GWAS identified 44 significant marker‐trait associations (MTAs) across almost the entire wheat genome linked to the 12 yield‐related traits, including four MTAs on chromosomes 2A, 2D, 4D, and 5A associated with FE. Several significant markers were identified in genomic regions previously reported, whereas others appeared to be potentially novel loci. Particularly, the co‐location of significant markers for yield‐related traits with major genes underlying plant development showed pleiotropic effects and the key role of these genes in modulating agronomic traits. The markers linked to FE, GFS, and SW are promising, especially considering that due to the destructive phenotypic determination, their improvement in early breeding generations can only be made by marker‐assisted selection. Taken together, these findings are encouraging and suggest the potential value of FE and associated traits as possible selection criteria to increase yield potential in wheat breeding programs.

Published: September 2019

Pedigrees provide suitable input for tracking breeding crosses and monitor plants and animal populations. Pedigree analysis is an essential tool to visualize and describe population structure and genetic diversity. Pasture plant breeding relies on a range of strategies from closed system recurrent selection using elite cultivars to diversity‐focused programs using ecotypes and wild germplasm as parents. There is currently no published pedigree analysis of white clover (Trifolium repens L.), despite over a century of breeding efforts in New Zealand. A pedigree map was constructed for white clover germplasm stored in the Margot Forde Germplasm Centre located in Palmerston North, New Zealand. Inbreeding and kinship coefficients and the effective number of founders through time were estimated to assess genetic relatedness in the reference population. A total of 15,265 accessions were included in the map. The maximum number of traced generations was 15, and the mean completeness of parentage for the reference population was 72%. The mean number of offspring was 5.14. The origin of founding and introduced accessions was assessed. The effective number of founders was 175.68 or 17.5% of the total number of reference founders. Founding accessions and influencing ancestors were identified. One of the earliest parental accessions identified was ‘North Canterbury Type I’ from 1941. Relatedness was determined using the k coefficient, with k = 1 as complete relatedness. The overall mean relatedness was k = 0.002. Overall mean inbreeding level was 0.39%. Relatedness and inbreeding coefficients revealed distinct germplasm pools formed across time that are of interest to pre‐breeding efforts.
Yield Responses of Wheat to Crop Residue Returning in China: A Meta‐Analysis
Authors: Qi Guangping , Kang Yanxia , Yin Minhua , Ma Yanlin , Bai Youshuai , Wang Jinheng
Published: September 2019

Crop residue returning (CRR) is known to improve the soil environment and thus increase crop production. However, the impacts of CRR on wheat (Triticum aestivum L.) yield have been contrary at times due to the differences in climatic conditions, soil traits, and management practices. These effects were evaluated using 351 paired observations published in 161 papers comprising studies conducted in 19 provinces (autonomous regions) of China. No publication bias or extreme values were found in the data, indicating that the analysis results are highly reliable. Compared with the practice of no crop residue returning (NCRR), the practice of CRR increased wheat yield significantly, on average by 8.29%, and proved more beneficial in Northwest China and in regions with average annual precipitation of 200 to 400 mm, average annual temperatures >11°C, sandy loam soil, and rotation with legumes (soybean [Glycine max (L.) Merr.]–wheat and pea [Pisum sativum L.]–wheat). The following aspects of CRR and crop management conferred greater benefits in yield: continuing the practice for 3 to 6 yr (compared with 1–2, 7–10, and ≥11 yr), using the residues at 3 to 6 t ha−1 (compared with <3, 6–9, and > 9 t ha−1), chopped straw (compared with intact straw), rainfed conditions (compared with irrigated conditions), and applying N at 200 to 300 kg ha−1 (compared with <100, 100–200, and >300 kg ha−1). The yield increase was significantly higher when the residues were returned in the form of mulch (12.56%) and for spring wheat (11.90%) than plowing them back into soil (4.53%) and for winter wheat (7.09%). The meta‐analysis thus confirms the benefits of CRR in higher wheat yields in China and also suggests that the benefits of CRR are site specific.

Published: September 2019

Reasonable use of water is required for the sustainable development of maize production in the North China Plain (NCP). In this study, straw mulching (SM) was evaluated in a 2‐yr field experiment to determine whether its effect on maize (Zea maysL.) yield and water use efficiency (WUE) differed under different irrigation systems. Compared with no mulching (NM) treatment, SM increased maize yield by 10.6 and 12.5% under a drip irrigation system in 2016 and 2017, respectively, which was mainly attributed to an 11.7 and 13.5% increase in total dry matter (DM). The increased soil water content in the 0‐ to 40‐cm layer at the six‐leaf (V6), silking (R1), and maturity (R6) stages for SM improved the soil mineral N content (Nmin) in that layer and then increased the N accumulation from V6 to R1 and post‐silking by 7.6 and 21.1% averaged over 2 yr compared with NM, respectively. The enhanced N accumulation for SM increased the leaf area index and DM accumulation rate, which increased the DM accumulation from V12 to R1 and post‐silking by 16.2 and 16.4% averaged over 2 yr compared with NM, respectively, and then the grain number and grain weight. Straw mulching also improved the WUE under the drip irrigation system due to the greater grain yield and 6.1% lower water consumption. This demonstrated that SM combined with the drip irrigation system effectively improved the yield and WUE of maize due to improved DM and N accumulation promoted by the increased water content and Nminin the upper soil layers.

Published: September 2019

In semiarid dryland farming regions, No‐till and intensified crop rotations may improve water use. Our objective was to determine water use efficiency (WUE) and precipitation use efficiency (PUE) for spring wheat (Triticum aestivum L.; SW) grown in crop sequences representing different levels of intensification, under minimum (Min‐till) or No‐till. Root zone (0–122 cm) water at planting (SWP) was 2.76 cm higher for two‐ and three‐phase sequences under Min‐till than continuous spring wheat (CSW), and sequences with fallow averaged 2.65 cm higher than those without. Conversely, SWP was unaffected by sequence under No‐till, with less effect of fallow. Root zone water at harvest was unaffected by the number of crop phases or fallow under Min‐till. However, values for CSW exceeded the two‐ or three‐phase sequences by 1.57 and 2.53 cm under No‐till, and sequences without fallow averaged 1.52 cm more than those with fallow. The highest WUE (8.4 kg grain ha−1 mm−1 water) was observed when SW was grown in three‐phase sequences compared with 7.7 kg grain ha−1 mm−1 water, for CSW and SW‐fallow. Spring wheat under Min‐till had higher WUE in sequences with fallow, but no effects of fallow occurred with No‐till. The lowest PUE (near 3 kg grain ha−1 mm−1 precipitation) and no effects of tillage were found in sequences with fallow. However, SW in continuously cropped sequences had PUE between 5.5 and 6.4 kg grain ha−1 mm−1 precipitation and was higher under No‐till. Both WUE and PUE are affected by intensification but may also be influenced by patterns of weather.

Core Ideas

Profile water varied as an interaction between crop sequence and tillage.

With fallow, soil water changed little the winter prior to planting.

Crop water use and yields were lower under continuous cropping than with fallow.

Water use efficiency was highest for three‐phase sequences but varied with yield.

Continuous cropping resulted in more efficient use of precipitation over the study.
Recalibration of Sensors in One of The World's Longest Running Automated Soil Moisture Monitoring Networks
Authors: Zhang Yongyong , Ochsner Tyson E. , Fiebrich Christopher A. , Illston Bradley G.
Published: September 2019

Obtaining accurate soil moisture data from sensors in automated monitoring networks is critical as these data are increasingly used for research in soil hydrology, ecohydrology, and related disciplines. One of the earliest such networks is the Oklahoma Mesonet, which monitors soil matric potential using heat dissipation sensors. Various calibration equations have been proposed for those sensors, and there is a need to compare and validate the performance of those equations, especially for matric potentials < –150 kPa. A laboratory experiment was conducted in silt loam soil using a sand‐kaolin box and a pressure plate apparatus with matric potentials ranging from 0 to –1500 kPa. The calibration equations included Starks’ equation, Flint et al.'s equation, Schneider et al.'s equation, and a new logistic equation. The upper limit of the sensors was ‐9 kPa, and the sensors remained responsive at ‐1500 kPa matric potential. The logistic equation produced the lowest root mean squared error (34 kPa), followed by Flint et al.'s equation (192 kPa), Starks’ equation (295 kPa), and Schneider et al.'s equation (463 kPa). After recalibration of the coefficients in the three preexisting equations, their performances improved, with all RMSE values ≤ 251 kPa; however, the logistic equation still provided superior accuracy. The logistic equation effectively removed an ∼ 0.02 cm3 cm−3 positive bias in soil water content that resulted from use of the original parameterization of Schneider et al.'s equation. This logistic equation is recommended for use with past and future data from the Oklahoma Mesonet's heat dissipation sensors.

Core Ideas

Soil matric potential data from the Oklahoma Mesonet are widely used.

Those data are estimated using a calibration equation shown here to be inaccurate.

The logistic equation developed here produces more accurate matric potential estimates.

Authors: Abdullahi Ibrahim Bello , Fakunmoju Segun Kamorudeen
Published: September 2019

This research examined the effect of market liquidity, inflation, and exchange rates on stock return in Nigerian Stock Exchange market. The researchers used ex-post facto design and employed secondary data subjected to Auto-regressive Distributive Lag (ARDL) bound test method of analysis within the period of twenty-one years. Findings reveal that in the short run, stock turnover, trading volume, exchange, and inflation rates have affected stock return positively and significantly. In the long run, market turnover has a positive effect. However, inflation and exchange rates have affected stock return negatively and significantly. Then, trading volume has a negative but insignificant effect on stock return, which is all at 5% level of significance. The researchers conclude that market liquidity, exchange, and inflation rates affect stock return. Therefore, the researchers recommend demutualization and transparent structures and adaptive method stabilization in exchange rate policies to increase stock market patronage, minimize transaction costs, and mitigate the market uncertainties.

Published: September 2019

This research aimed at investigating the male and female students’ preferences on the six types of Oral Corrective Feedback (OCF). This qualitative research used observation and interview to collect data. The observation was done to know the practice of the six types of OCF in speaking class and the interview was conducted to reveal the students’ preferences for OCF. The result from the observation shows that the lecturer mostly uses Explicit Correction to correct the students’ error. Then, the result from the interview indicates that male students prefer to have Explicit Correction because this type is the easiest type to know the error and correction clearly. Whereas the female students prefer to have Recast and Metalinguistic Feedback because Recast does not encourage them and Metalinguistic Feedback can make them think critically under the lecturer’s clue. Subsequently, both male and female students perceive Clarification Request and Repetition as the ambiguous type to grasp what the lecturer’s mean. The result of this current research is expected to provide an additional information about the practice of OCF strategies in speaking classroom which is appropriate with the students’ preferences.

Authors: Sultan Sultan , Jufri Jufri
Published: September 2019

This research examined teacher’s control of classroom interaction. Studying teachers’ controlling behaviors as a form of antisocial communication was necessary to develop teachers’ pedagogical competence and teacher-student relationships that were empowering and equitable. It employed a qualitative approach to critical discourse analysis. The respondents are six Indonesian Language teachers. Data collection was conducted by video recording, observation, and interview. Data were analyzed at the micro (text) and macro (social context) level. Research findings show that teacher’s control of classroom interaction might be realized in the acts of interrupting students, enforcing explicitness, controlling topic, formulating, restricting students’ contribution, asking close-ended questions, and ignoring students’ contribution. Teacher’s antisocial communication represented through various types of controls which can hinder the development of students’ language skills and adversely affect learning climates and students’ psychological aspects. Teacher’s beliefs and perspectives, teacher’s social status, and teacher’s pedagogical competence can be considered as factors that is able to contribute to practice of teacher’s control of students in classroom interaction.
Translingual Negotiation Strategies Used by English Students to Build Classroom Interaction in a Translation Class
Authors: Roza Veni
Published: September 2019

This research aimed at revealing what kind of translingual strategies that were practiced by the sixth-semester students to build interaction in the translation class. This qualitative research conducted through observing students’ interaction in translation class (using English, bahasa Indonesia, and Minangkabau languages). The researcher finds that four macro strategies proposed by Canagarajah (2013): envoicing, recontextualization, interactional, and entextualization strategies are consciously used by students during communication. Envoicing strategies are used by way of word coinage, foreignization, as well as code switching and code mixing dominantly by students while asking and clarifying information. Recontextualization  strategies are done through the use of the feature of linguistic form such formulaic Islamic greeting in Arabic preceding the talk. Interactional strategies used are confirmation check, check, clarification request, and recast. Interestingly more competent students use simplification in communication, and less competent speakers use leveling as entextualizationstrategies. The use of these strategies in speaking helps students (as speakers) to establish classroom interaction.
Native and Non-Native Listeners Perceptual Judgement of English Accentedness, Intelligibility, and Acceptability of Indonesian Speakers
Authors: Zahro Syifa' Khuriyatuz
Published: September 2019

This research aimed at investigating the extent of accentedness and intelligibility as well as the acceptability of Indonesian foreign-accented speech perceived by native and non-native listeners, as well as finding their correlation to each other. It used qualitative research. The participant of the research was selected using purposive sampling. The participants were divided into speakers and listeners. There are six speakers and four listeners selected. The four listeners were native and nonnative listeners who rated and transcribed six recorded reading of Indonesian speakers by means of SPIN (Speech Perception in Noise) test. The results show that native listeners rate the speech almost the same way as non-native listeners do. The speeches with clear and accurate pronunciation are rated highly accepted and fully intelligible, regardless of having a very strong accent. In contrast, less clear and accurate pronunciations, as well as a very strong accent of the speeches, are rated unacceptable and still reasonably intelligible. The result of the correlation test between accentedness and intelligibility as well as accentedness and acceptability of the accent finds on no account of correlation to each other. Therefore, accentedness and intelligibility plus accentedness and acceptability of the accent are independent, so that strong foreign accent could stay acceptable and intelligible. The factors found to influence the judgment are the familiarity of the accent, clarity, and accuracy of pronunciation. Aforementioned findings have implication to challenge English teachers in Indonesia to develop meaningful activities to teach English pronunciation accurately to be regarded as fully intelligible and acceptable by listeners, especially native English listeners.

Published: September 2019

This research aimed to analyze the acceptance level of the tax e-filing system on the tax compliance of the individual taxpayer. UTAUT had underpinned this research that consisted of the aspects of Performance Expectancy (PE), Effort Expectancy (EE), Social Influence  (SI), and Facilitating Condition (FC). These factors were expected to trigger the taxpayer attitude which will be impact on their behavioral intention. Using a qualitative research approach, an interview with 16 individual taxpayers with certain criteria was conducted. The interview questions were derived from the UTAUT aspects. Moreover, all interview scripts segmented into three distinct classifications; age, gender, and occupation. The interview data were analyzed using Nvivo 12. The result shows that tax e-filing system is effective to stimulate the commitment of the participant, not only to use the system regularly and to report their tax return but also to fulfill their tax obligation voluntarily. The e-filing system increases participant productivity because it offers cost reduction and time-saving. Furthermore, it is easy to understand and effortless to use. However, SI has less impact on the participant' decision to use tax e-filing system since it is mandatory in accordance with the tax regulation. Regarding the FC, it is sufficient to develop people interest in using the e-filing system. This result could be a beneficial source for the Directorate General of Taxes to evaluate the e-filing implementation and for Indonesia citizen to actively involved

Percepção Ambiental de Unidades de Conservação: O Olhar da Comunidade Rural do Barrocão no Entorno do Parque Estadual da Serra do Conduru – BA
Authors: Ferreira Damile Jesus , Profice Christiana Cabicieri
Published: September 2019

A atual relação entre ser humano-natureza que é estabelecida na sociedade capitalista é caracterizada pela dominação e degradação dos ambientes naturais. Assim, para a política ambiental, as Unidades de Conservação (UCs) de proteção integral são a garantia da conservação da biodiversidade, embora não haja ainda o reconhecimento do importante papel das comunidades locais no manejo sustentável dos recursos, no processo de gestão ambiental e na conservação da biodiversidade. Diante disto, o objetivo deste trabalho foi compreender a percepção ambiental dos moradores da comunidade rural do Barrocão (Uruçuca-BA) localizada no entorno do Parque Estadual da Serra do Conduru (PESC), identificando o tipo de relação que é estabelecida entre a comunidade e o PESC. O estudo trata-se de uma pesquisa quali-quantitativa, possuindo a fenomenologia como sua matriz teórico-metodológica. O método de coleta foi o uso de entrevistas semiestruturadas com 13 moradores integrantes da associação comunitária Doces e Segredos da Floresta, partindo de um roteiro elaborado seguindo as orientações metodológicas da percepção ambiental de Whyte (1977). As análises mostraram um distanciamento entre a gestão do PESC com a comunidade local, evidenciando a ausência da participação dos moradores nos processos de criação e gestão da UC. Apesar de estabelecerem uma relação conflitante com a unidade, os moradores reconhecem a função do parque e o consideram importante na conservação do meio ambiente.

Utilizando-se do método histórico comparativo em uma perspectiva interdisciplinar, principalmente, pelo diálogo da história, urbanismo, arquitetura, paisagismo e educação o presente artigo pretende fazer, além de discussões sobre preservação ambiental, sustentabilidade e qualidade de vida em ambiente urbano, compreender como os habitantes da cidade foram mudando a sua forma de se relacionar com o meio natural ao longo dos anos. Goiânia foi pensada e idealizada para ser, além uma cidade planejada no estilo arquitetônico de cidades-jardim, a futura capital de Goiás que nascia se aproximava dos princípios de uma urbanização sustentável que procurava manter o equilíbrio entre a natureza, economia e sociedade. Utilizando-se de uma documentação variada - planta e plano diretor elaborados por Atílio Corrêa Lima, registros de fotos aéreas, mapas das áreas destinadas a parques e bosques, projetos urbanísticos e planos diretores, relatório urbanístico, dados populacionais, plantas de urbanização de bairros, mapas de loteamentos legais e ilegais - o artigo pretende mostrar que o projeto de construção de Goiânia idealizado por Atílio Corrêa Lima entrevia uma interação entre a cidade, o homem e a natureza ao destinar amplos espaços para a construção de praças, jardins e áreas verdes para o lazer, tendo em vista também, a preservação dos recursos naturais essenciais à a uma cidade que poderia abrigar até 50 mil habitantes. No entanto a partir de 1950 o êxodo rural provocando pela expansão da fronteira agrícola para o Centro-Oeste levou a uma expansão acelerada e desordenada de Goiânia, e consequentemente, a expansão da malha urbana sobre as áreas que deveriam ser de conservação e preservação.
A Influência do Paradigma Biológico na Filosofia do Século XX: A Epistemologia Darwinista de Karl Popper
Authors: Barroso Marco Antônio , Sá Camila de Oliveira
Published: September 2019

Karl Raimund Popper é um epistemólogo que busca fazer conexões entre a produção científica e o evolucionismo de Darwin. Suas pesquisas são desenvolvidas a partir de questões sobre o método científico, a filosofia política e as ciências sociais, apresentando a teoria dos três mundos. O filósofo em questão estuda diversas teorias e hipóteses e as conceitua como teoria ou um programa metafísico conforme as características que apresentam. Esse trabalho teve como objetivo evidenciar a relação entre as teorias de Popper e a darwinista. Para Popper, o darwinismo é enquadrado no mundo 3 e é um programa metafísico de pesquisa, por não ser verossímel e falsificável. O darwinismo assim como os pensamentos de Popper, conforme ele mesmo admite, são pesquisas que irão fornecer bases para que outros pesquisadores possam responder as questões levantadas por aquelas. Contudo, pode-se perceber que há falhas na reflexão do filósofo a respeito de alguns termos da teoria evolutiva, como seleção natural e especiação.

In the present review, we describe the potential of root powder of yellow gentian (Gentiana lutea) for the prevention of obesity and diabetes including complications related to this disease.

Conclusion::

Reasonably effective, low-cost alternatives could fulfill an important role for a large part of the human population and could be of great value for the food market. Even a modest reduction of morbidity and mortality with respect to this disease translates into millions of lives saved.
Trehalose Protects against Insulin Resistance-Induced Tissue Injury and Excessive Autophagy in Skeletal Muscles and Kidney
Authors: Yu Wei , Zha Wenliang , Peng Hu , Wang Qiurong , Zhang Shuning , Ren Jun
Published: September 2019

Background::

Insulin resistance refers to a pathological state of compromised sensitivity of insulin to
promote glucose uptake and utilization, resulting in compensatory excessive insulin secretion and hyperinsulinemia
in an effort to maintain glucose homeostasis. Akt2 represents an important member of the Akt family and
plays an essential role in the maintenance of insulin signaling.

Methods::

This study was designed to examine the effects of trehalose on kidney and skeletal muscle (rectus
femoris muscle) injury in an Akt2 knockout-induced model of insulin resistance. Akt2 knockout (Akt2-/-) and
adult WT mice were treated with trehalose (1 mg/g/d) intraperitoneally for 2 days, followed by providing 2%
trehalose in drinking water for 2 months. Intraperitoneal glucose tolerance test (IPGTT), protein carbonyl content
and mitochondrial function (aconitase activity) were examined. Apoptosis and autophagy protein markers were
monitored using western blot analysis.

Results::

Akt2 ablation impaired glucose tolerance, promoted protein carbonyl formation and decreased aconitase
activity in kidney and skeletal muscles, associated with pronounced apoptosis and overt autophagy, the effects of
which, with the exception of IPGTT, were greatly ameliorated or negated by trehalose treatment. Moreover,
phosphorylation of mTOR was downregulated in both kidney and skeletal muscles from Akt2-/- mice, the effect of
which was attenuated by trehalose. Levels of Akt (pan and Akt2) were much lower in Akt2-/- mice, the effect of
which was unaffected by trehalose treatment although trehalose itself upregulated Akt levels.

Conclusion::

These data suggest that the autophagy inducer trehalose rescued against insulin resistance-induced
kidney and skeletal muscle injury, apoptosis and excessive autophagy, possibly in association with restored
mTOR phosphorylation without affecting Akt.
Azelaic Acid: A Promising Agent for Dermatological Applications
Authors: Kumar Anil , Rao Rekha , Yadav Poonam
Published: September 2019

Azelaic Acid (AA) is a naturally occurring 9-carbon straight-chain saturated dicarboxylic acid widely found in wheat, rye, and barley. It has been shown to possess numerous biochemical activities, such as anti-inflammatory, anti-microbial, antioxidant, anticomedolytic and anticancer. This therapeutic agent has been approved by US food Drug Administration for the treatment of mild to moderate acne and rosacea. Further, azelaic acid has been reported for the management of skin hyperpigmentation, melasma and alopecia. In this review article, several studies on azelaic acid that pointed out its bioactivities and pharmacology along with its drug delivery systems are reviewed. Additionally, an outlook on its mechanism of action is also given. Azelaic acid is an important moiety for the management of acne owing to its benefits in addressing follicular excess sebum, inflammatory action, hyperproliferation and activity against Propionibacterium acne. The commercially available topical formulations normally contain 15 to 20% AA. In the future, a broadspectrum antibacterial agent, azelaic acid can act as a pillar in acne therapy minimizing the potential risk of emergence of resistance. This review will definitely provide a new perspective for research involving this bioactive molecule.
Effect of the Histone Deacetylases Inhibitors on the Differentiation of Stem Cells in Bone Damage Repairing and Regeneration
Authors: Lu Wei , Ji Jun , Zhao Qing , Ji Kun , Wang Tiancong , Li Guifeng
Published: September 2019

Tissue damage repairing and regeneration is a research hot topic. Tissue engineering arises at the historic moment which is a defect repair compound composed of seed cells, tissue engineering scaffolds, and inducing factors. Stem cells have a limited growth period in vitro culture, and they have a pattern of replicating ageing, and these disadvantages are limiting the applications of stem cells in basic research and clinical treatment. The enhancement of stem cell differentiation ability is a difficult problem to overcome, and it is possible to enhance the differentiation ability of stem cells through histone modification so as to provide a more robust foundation for damage repairing and regeneration. Studies have shown that Histone Deacetylases (HDAC) inhibitors can improve mesenchymal stem cells in vitro induced in different directions, conversion efficiency, increasing the feasibility and safety of stem cell therapy and tissue engineering, to offer reference to promote the stem cell therapy in clinical application. Therefore, this paper mainly focusing on the usage and achievements of the deacetylase inhibitors in stem cell differentiation studies and their use and prospects in repair of bone tissue defects.

Published: September 2019

Background:

Cordycepin (Cor), one of the major bioactive components of the traditional
Chinese medicine Cordyceps militaris, has been used in clinical practice for several years. However,
its neuroprotective effect remains unknown.

Aim:

The purpose of the study was to evaluate the neuroprotective effects of Cor using a rotenoneinduced
Parkinson’s Disease (PD) rat model and to delineate the possible associated molecular mechanisms.

Methods:

In vivo, behavioural tests were performed based on the 10-point scale and grid tests. Levels
of dopamine and its metabolites in the striatum and the numbers of TH-positive neurons in the Substantia
Nigra pars compacta (SNpc) were investigated by high-performance liquid chromatography
with electrochemical detection and immunohistochemical staining, respectively. In vitro, cell apoptosis
rates and Mitochondrial Membrane Potential (MMP) were analysed by flow cytometry and the
mRNA and protein levels of Bax, Bcl-2, Bcl-xL, Cytochrome c (Cyt-c), and caspase-3 were determined
by quantitative real-time PCR and western blotting.

Results:

Showed that Cor significantly improved dyskinesia, increased the numbers of TH-positive
neurons in the SNpc, and maintained levels of dopamine and its metabolites in the striatum in rotenone-
induced PD rats. We also found that apoptosis was suppressed and the loss of MMP was reversed
with Cor treatment. Furthermore, Cor markedly down-regulated the expression of Bax, upregulated
Bcl-2 and Bcl-xL, inhibited the activation of caspase-3, and decreased the release of Cyt-c
from the mitochondria to the cytoplasm, as compared to those in the rotenone-treated group.

Conclusion:

Therefore, Cor protected dopamine neurons against rotenone-induced apoptosis by improving
mitochondrial dysfunction in a PD model, demonstrating its therapeutic potential for this disease.
