Um percurso meditativo por algumas florestas na arte
Authors: Rama Samuel
Published: November 2019

A grande floresta europeia densa e obscura desapareceu proporcionalmente ao crescimento das cidades sobretudo a partir da modernidade. Na mesma medida do desaparecimento das florestas reais dá-se o seu incremento no território da cultura em geral e nas artes plásticas em particular. A floresta assume-se assim como arquétipo ou índice do natural e é nos seus melhores exemplos da arte sempre revisitada por uma persistente expressão atravessada pelo sonho e pela nostalgia. Nas representações de florestas feitas por artistas que quiseram recuperar, do pondo de vista estético, estas paisagens a partir de dentro, podemos encontrar talvez uma das raízes mais longínquas do questionamento ou da relativização da ideia de paisagem enquanto vista ou janela, a favor de uma ideia de paisagem enquanto errância ou envolvimento. Esse questionamento parece trazer também consigo a expressão ou tradução do fundamento ético primeiro que faz reconhecer a natureza como algo absolutamente superior ao homem. Tal acontece porque a maioria das representações de florestas feitas a partir do seu interior revelam um certo carácter estético negativo que induz no espectador mobilidade, desconforto, estranhamento obrigando-o a indagar e articular juntamente estética e ética.
Latitude e longitude. A paisagem como irresolução
Authors: Monteiro Hugo
Published: November 2019

Este texto pretende pensar a paisagem de acordo com dois eixos fundamentais: latitude, relativo às categorias de espaço e de movimento; longitude, relativo aos motivos da altitude, elevação e alteridade. Estes dispositivos conceituais visam dar lugar à “irresolução” como parte significativa da experiência estética da paisagem. Latitude and longitude.

Origens do Cristo Crucificado em Portugal
Authors: Valle Marco Antonio Alves do
Published: November 2019

Em um antiqüíssimo mosteiro de monjas beneditinas, localizado na aldeia de Bouças, se venerou desde eras imemoriais, anteriores ou contemporâneas da formação da nacionalidade portuguesa, a imagem artística do Cristo Crucificado, a qual se atribuía dons sobrenaturais, tornando-se por isso, objeto de ardente devoção que só fez crescer através dos tempos chegando aos nossos dias. Reflexões sobre a inclusão, ou não, da imagem de Bom Jesus de Matosinhos ao Passo da Cricificação de Congonhas do Campo pelo "Aleijadinho".
Mise-en-scène em Laura Ribero e Hitchcock
Authors: Almeida Anderson Diego
Published: November 2019

O artigo estabelece relações entre a obra de Laura Ribero e a estética noir, partindo da concepção da imagem não só enquanto índice, mas também como imaginação. A atuação da fotógrafa é analisada conforme os elementos também presentes nos filmes de Hitchcock, como o suspense, a fantasia, os contrastes entre o claro e o escuro. Assim como em Hitchcock, a mise-en-scène de Laura Ribero é pontuada pelo curioso, pelo inesperado e pelo misterioso, revelando ao espectador a coexistência das suas duas identidades (a empregada e a fotógrafa) e a interlocução com o espaço. Sua fotografia é fortalecida pelo imaginário que gira em torno dela, motor das suas construções ficcionais, de uma estética permeada pelo noir.
O artista que teoriza. Do confronto ao desconfronto
Authors: Abade Jorge
Published: November 2019

O artigo versa, essencialmente, sobre os principais problemas com que um artista se depara quando faz investigação: a que é inerente ao ato criativo mas, principalmente, a uma investigação paralela ou combinada com essa atividade de criação artística, academicamente apelidada de científica, de cariz teórico. Indigita também, no entanto, a pertinência dessa atividade dupla simultânea, nomeadamente por serem empreendimentos que poderão estar mutuamente enredados.
A intertextualidade na arte brasileira de Glauco Rodrigues
Authors: Floridia Marília Longo Araújo
Published: November 2019

Neste artigo, investigamos a intertextualidade na obra do artista plástico Glauco Rodrigues (1929-2004) que possibilita o diálogo com diversos artistas. Nesse processo, buscamos conhecer a sua trajetória artística para compreender como a intertextualidade torna-se enfática no seu trabalho. O desenvolvimento da sua comunicação visual se inicia com um realismo regional, passa pela arte abstrata, e retorna ao figurativo sob o impacto da Pop Art. Diante deste percurso, Glauco Rodrigues passa a desenvolver uma linguagem visual brasilianista e antropofágica. Partimos do pressuposto que para apreciação crítica das artes plásticas faz-se necessária uma investigação do objeto de arte. Para tanto, selecionamos quatro trabalhos do artista para análise dos seus elementos de composição. Os quadros de Glauco Rodrigues contêm uma iconografia brasileira que resgata por meio da intertextualidade a nossa herança pictórica.
Fotografia, paisagem, deslocamento
Authors: Neves Alexandre Emerick , Silva Camila de Souza
Published: November 2019

Tema recorrente na arte contemporânea, a construção de paisagens é exemplificada aqui por obras como as de Olafur Eliasson e Douglas Huebler, com apoio na ideia de construção de paisagem apresentada por Javier Maderuelo. Propomos um aprofundamento da questão com base na apropriação de imagens fotográficas por meio de deslocamentos virtuais pela web em obras como as de Corine Vionnet, sobretudo a partir da convergência dos conceitos heideggerianos de habitar e construir com o conceito de espaço discursivo da fotografia de Rosalind Krauss. Diante disso, segue como estudo de caso um projeto da artista Camila Silva intitulado Caballos de paseo, que tem o livro como lugar de retorno e de novas partidas para deslocamentos pelos espaços discursivos da arte contemporânea.

Entre building cuts e alterations to a suburban house
Authors: Santos Fábio Lopes de Souza , Sampaio Rafael de Oliveira , Almeida Rafael Goffinet de
Published: November 2019

A inclusão do espaço como uma questão artística delineou nas trajetórias de Gordon Matta-Clark e Dan Graham um profundo interesse sobre as transformações da arquitetura e da cidade. Este artigo pretende analisar comparativamente algumas de suas propostas enfocando esta problemática para debater a construção dos espaços contemporâneos. Nesta tarefa, alguns referenciais teóricos provindos da arte e da arquitetura iluminarão questões centrais na prática e no pensamento de ambos os campos, sobretudo em relação a como o questionamento físico e discursivo das convenções que regiam o “objeto” e o “espaço” artísticos serviram de base para a crítica destes artistas sobre as convenções de tantos outros espaços constitutivos do cotidiano urbano.

A visibilidade pura
Authors: Barros José D'Assunção
Published: November 2019

Este artigo busca explorar a perspectiva de uma Historiografia Comparada da Arte, analisando as abordagens de dois importantes historiadores da Arte: Alois Riegl (1858-1905) e Heinrich Wölfflin (1864-1945). Os dois historiadores da arte examinados correspondem a um ambiente intelectual similar, uma vez que não estão distanciados no tempo e pertencem à mesma corrente historiográfica de análise da arte: a escola de Viena de Historiografia da Arte. Esta corrente, cujas bases teóricas ficaram conhecidas como “Teoria da Visibilidade Pura”, será o objeto de apreensão deste artigo.
O diálogo das estrelas
Authors: Veloso Sainy Coelho Borges
Published: November 2019

O artigo sintetiza um olhar/pensamento sobre a obra artística de Silvio Nunes Pinto, trabalhador rural que, no exercício de suas atividades cotidianas e para atender às demandas de suas realidades concreta e psíquica, produziu objetos ricos em detalhes e acabamentos, apesar de não se restringir somente às funções a elas destinadas. Sua obra é regida pela demanda imaginária e criativa que fabrica e dá forma à matéria indistinta da doméstica e distinta do sistema de arte. Para pensar sua poética do silêncio, recorri ao poema “Um lance de dados jamais abolirá o acaso” de Mallarmé (2014) de maneira associativa, e interdisciplinaridade de autores como Jacques Lacan (1982, 1985, 1992); Gilbert Durand (1989); Homi Bhabha (2007), entre outros.
Fenômenos latentes
Authors: Medina Erik Nardini
Published: November 2019

O presente artigo propõe aproximações entre as noções de inconsciente óptico benjaminianas e as ideias de redução fenomenológica descritas por Moles. O texto utiliza tais conceitos para explorar o universo das fotografias científicas tradicionais ­– de fenômenos muito pequenos, muito distantes, excessivamente rápidos ou notadamente lentos. Reconhecendo que tais fenômenos não são visíveis a partir da óptica natural, o artigo constrói uma narrativa que revela como determinados métodos são adotados na apreensão e no visionamento de fenômenos latentes, os quais se apresentam eles mesmos em escalas espaço-temporais distintas, observáveis apenas a partir de próteses: mecanismos de fazer-ver.
Arquivo e hibridização
Authors: Siebert Manuela Cristina
Published: November 2019

O presente artigo busca analisar o arquivo como um sistema de potenciais hibridizações, as quais permitem conexões entre percepções e/ou sensibilidades que podem ser, à priori, consideradas distantes ou desconexas. Essas questões serão discutidas a partir da obra do artista Paulo Gaiad e das interpretações múltiplas que ela sugere devido às hibridizações presentes nela, não só pelo viés da fatura e das suas obras de técnica denominada "mista", mas também pelo discurso do próprio artista.  A questão da multiplicidade interpretativa na obra de Gaiad será colocada em um diálogo com o texto "O Banquete" de Platão, no qual essa questão é debatida a cerca do sentimento do amor.
The HbCO Concentration on Blood of Motorcycle Mechanic Workshop in Surabaya - A Cross-Sectional Study
Authors: Ayuningtyas Citra
Published: November 2019

Carbon monoxide was one of the indicators of air pollution that most often comes from motor vehicles. Indirectly, increasing the number of motorcycles would be followed by an increase in the number of workshops that provide maintenance services. The process of maintenance and repair in the workshop causes carbon monoxide (CO) levels in the air to be higher from the standard so it was easily inhaled by workers and the internal mechanism reacts became carboxyhemoglobin (HbCO). This study aims to analyze the effect of CO levels in the workshop air and smoking habits of workers on HbCO levels in the blood of workshop mechanic workers. This research was an observational analytic study with 18 respondents as workshop mechanic workers who were male. Respondents in this study were identified based on age, years of service, length of work, use of Personal Protective Equipment (PPE), and nutritional status. The results showed that most respondents aged 25-36 years -old (38,9%), had a year of service ≥ 5 years (55,6%), had smoking habits (72,2%), did not use PPE (88,9%) and had a normal nutritional status (47,2%). CO levels in the air had a significant correlation on HbCO levels (p <0,000) as well as smoking habits also had a significant correlation on HbCO levels (p <0,000). It was recommended for workers to reduce smoking habits, improved healthy lifestyles, and used masks to reduce exposure to pollutants.

Authors: Tolinggi Safrudin , Dengo Moh. Rivandi
Published: November 2019

All countries of ASEAN member agree that dengue fever is one of the major problems faced by all ASEAN countries so the status of their territory has been determined to be hyperendemic in the last 10 years. Global warming is predicted to result in an increase in the average temperature of the earth's surface by 2,0OC to 4,5OC in 2100, which will have a direct impact on diseases caused by vectors. This study aims to examine the relationship of climate factors to the incidence of dengue fever and find a predictive model of dengue fever in Gorontalo regency. This research data used secondary data from 2012-2016, which included climate data (average temperature, irradiation time, rainfall, rainy days, and average wind speed) per month obtained from the Meteorology and Geophysics Agency (MGA) Gorontalo Class II and dengue fever incidence data were monthly incident data obtained from the Health Office Gorontalo regency. Based on the values of determinant values (R2) of the five models that were obtained, the value is 13,4% with p value = 0,004 and the linear regression equation using the backward method. Thus, estimated number of cases of dengue fever in Gorontalo Regency in a year reached 132 cases. Besides climate factors, the increasing number of cases of dengue fever might be caused by urbanization, population density, high population mobilization, community behavior, existence and quality of facilities and health services obtained by the community. Improvisation is needed for planning prevention programs and its implementation. As well as designing spatial-based disease prevention and control program that analyzes all climate, demographic and environmental parameters that are the causes of the high incidence of dengue fever.

In this work, a xylan-based antimicrobial additive agent was prepared and aimed for uses in paper products against Escherichia coli bacteria. The derived Cationic-Xylan-grafted-PHGH (CX-g-PHGH) was successfully synthesized by graft copolymerization of cationic-xylan with guanidine polymer (PHGH) using ceric ammonium nitrate as initiator. The obtained CX-g-PHGH had maximum PHGH grafting ratio of 18.45% and efficiency of 58.45%, and showed good viscosity and thermal stability. Furthermore, the paper samples prepared in this work were reinforced obviously with the addition of CX-g-PHGH by improved mechanical properties. Compared to the reference paper without any of the xylan-derivatives, the index of tensile, tear, burst and folding endurance of the paper had increases up to 20.07%, 25.31%, 30.20% and 77.78%, respectively. Moreover, the prepared CX-g-PHGH paper exhibited an efficient antimicrobial activity against E. coli bacterial, by which a lot of applications based on the new xylan-derived additive agent obtained in this work could be found, especially in field of antimicrobial paper products against E. Coli bacteria from contaminated food.

Published: November 2019

AMC (Aluminium Matrix Composite) is material which has a great potential for being developed. This research was done to find effect added of Cu variation for impact strength and microstructure on Al-Si composite. Mass fractions of sand silika is 3% and Cu variation adding is 0, 1, 2, 3 & 4%. Composite manufacture is using stir casting method with stirring 600 rpm during of 5 minutes on semi solid temperature. Speciments were tested using optical microscope and impact charpy testing machine. The value impact of composite without adding Cu is 0,333 J/mm2 after added Cu value down. Until adding Cu 4% the value impact is 0,104 J/mm2. Micro photograph showed the result of porosity and SiO2 unform distribution with the adding of Cu to the composite. From the test results it is known that the strength of the impact decreases with mass fraction addition Cu. This is because the addition of Cu can increase the porosity and formed CuAl2 phase which are brittle.

Published: November 2019

Urinary tract infection (UTI) during pregnancy is assumed to be associated with increased maternal and fetal morbidity and mortality; hence, a proper assessment of knowledge and practices is crucial to formulate preventive strategies to ensure the health of both the mother and the baby. The study determined the knowledge, attitude, practices (KAP), and the beliefs of pregnant women about UTI based on the Health Belief Model. A survey questionnaire was used to gather data from pregnant women with and without UTI. The association of the pregnant women’s sociodemographic characteristics with their KAP and health beliefs was determined using Pearson’s chi-square test. Results of the study showed that the majority of pregnant women have unsatisfactory knowledge with a positive attitude and good hygienic practices against UTI. Educational qualification and socioeconomic status showed a significant association with the KAP of pregnant women. Positive attitude and satisfactory hygienic practices were evident among the respondents despite their unsatisfactory knowledge. The salient traits of the Filipino women are exhibited on the descriptive of the Health Belief Model that include being resilient amid a problem and considering difficulties not as barriers but opportunities to make life healthier and better.

Background

Ttralogy of Fallot (TOF) is a severe type of congenital heart disease (CHD) and confers substantial risk to mother and fetus. However, the outcomes of pregnant women with TOF have not been well studied.Methods

Women with TOF who has been seen and/or delivered at our tertiary-care hospital between April 2008 and January 2018 were retrospective reviewed.Results

A total of 31 TOF patients with pregnancies were identified in ten-year period. Among these patients, cardiac defects were surgically repaired in 19 cases and remained uncorrected in 12 women. The frequency of miscarriages and preterm birth was greater in the uncorrected group (16.67% vs one, and 50% vs 5.26%, respectively). The percentage of babies who were small for gestational age (SGA) was 41.67% and 10.53% in two groups. The neonatal mortality and fetal mortality were observed in women without correction for TOF, which were 3.23% (1/31) and 6.45(2/31), respectively. Maternal and neonatal risk appeared to be associated with heart functional classifications, pulmonary hypertension and histories of cardiac events such as serious cardiac arrhythmias.Conclusions

Obstetric and cardiac complications are more frequently present in the pregnant women with uncorrected TOF. Surgical correction is associated with improved maternal and perinatal outcome.

Background Taurolidine is thought to be an alternative antimicrobial in periodontal therapy. The purpose of this follow-up taurolidine study was to determine in more detail the mode of action of taurolidine against bacterial species being associated with periodontal disease. Further, a potential development of resistance against taurolidine in comparison with minocycline was to evaluate. Results Visualizing the mode of action of taurolidine to Porphyromonas gingivalis by scanning and transmission electron micrographs showed in part pores and release of constituents from the cell wall. The interaction of taurolidin with bacterial cell wall is also supported by the finding that taurolidine inhibited in a concentration-dependent manner the activities of LPS and of the P. gingivalis arginine-specific gingipains. However, an effect on A. actinomycetemcomitans leukotoxin was not found. When transferring 14 clinical isolates from subgingival biofilm samples (4 P. gingivalis, 2 A. actinomycetemcomitans, 2 Tannerella forsythia, 2 Fusobacterium nucleatum, 4 oral streptococci) on agar plates containing subinhibitory concentrations of taurolidine up to 50 passages, one P. gingivalis strain developed a resistance against taurolidine which was probably linked with efflux mechanisms. When antimicrobial pressure was removed, MIC reverted to baseline value. Testing development of resistance to minocycline in a similar way, an increase of MIC values occurred in five of the 14 included strains after exposure to subinhibitory concentrations of the antibiotic. Efflux might play a role in one A. actinomycetemcomitans strains, but obviously not in the other four strains. Removing antimicrobial pressure for a few passages did not revert the increased MIC values. Conclusion Taurolidine interacts with LPS and gingipains. Development of resistance seems to be a rare event when applying taurolidine. A potential development of resistance might be associated with efflux mechanisms.

Background: Poor ovarian response (POR), a manifestation of low ovarian reserve and ovarian aging , leads to a significantly reduced pregnancy rate after in vitro fertilization-embryo transfer (IVF-ET) . Acupuncture is effective at improving ovarian reserve. The purpose of this study is to evaluate the effect of acupuncture on increasing the number of retrieved oocytes after controlled ovarian hyperstimulation (COH) in women with POR. Methods: This is a multicenter randomized controlled trial . A total of 140 women with POR will be randomly assigned to receive acupuncture or non-treatment for 12 weeks before COH. The primary outcome will be the number of retrieved oocytes. The secondary outcomes include antral follicle count (AFC), serum level of anti-müllerian hormone (AMH), basal serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) , the score of the self-rating anxiety scale (SAS), the fertilization rate, the cleavage rate, the available embryo rate and the high-quality embryo rate. The safety of acupuncture will also be assessed. Discussion: The results of this trial will identify the effectiveness of acupuncture in the treatment of POR. This will provide a new treatment option for POR patients and physicians.

Published: November 2019

Background: The loss of life ability of patients after stroke is mostly caused by the dysfunction of upper limbs, especially hands. Hand functional exercise is the premise of alleviating hand dysfunction, and the relief of hand spasm is the basis of timely and effective hand functional exercise. Previous clinical observation showed that fascial point needling could effectively alleviate hand spasm immediately after stroke, but further evidence from large sample studies is needed. The overall objective of this trial is to further evaluate the clinical efficacy of fascial point acupuncture on hand spasm after stroke. Methods/design: This multicenter randomized controlled trial will compare the efficacy of fascial point acupuncture versus sham acupuncture and routine rehabilitation therapy in stroke patients with hand spasm. Patients will be randomized to undergo either the fascial point acupuncture or the sham acupuncture or the control (routine rehabilitation therapy). We will recruit 210 stroke inpatients who meet the trial criteria and observe the remission of hand spasm and improvement of limb function after 4 weeks of intervention. The first evaluation indexes are the remission of hand spasm and the duration of spasm remission. The second evaluation indexes are the hand function of affected limbs and the ability of daily living. When the accumulative total number of cases included reaches 120, a mid-term analysis will be conducted to determine any evidence that experimental intervention does have an advantage. Discussion: Our aim is to evaluate the efficacy of fascial point acupuncture in relieving hand spasm after stroke. The results will provide more evidences for the clinical application of this therapy in the future. Trial registration: The trial has been registered at the Chinese Clinical Trial Registry（ChiCTR）on April 9, 2019.

Published: November 2019

Background: Obesity is rising in developing countries like India and is associated with an increase in cardiometabolic problems. Rising incomes, rapid urbanization, and mechanization have induced lifestyle changes like consumption of more obesogenic foods and sedentary habits at work and leisure, contributing to a transition from under- to over-nutrition. This study maps the prevalence of adult (15-49 years) overweight and obesity across regions and socioeconomic groups in India, and estimates its association with lifestyle, health environment, dietary patterns, diabetes, and hypertension.Methods: We employ a combination of 3 latest nationally representative datasets with over 700,000 adults. We use a linear probability regression model to identify the correlates of overweight/obesity and their relative magnitudes. We use intra-household regression to identify differences between men and women and coarsened exact matching to causally estimate the impact of obesity on diabetes and hypertension.Results: Overweight/obesity rates have increased across all states, in rural and urban areas, and for all wealth levels. Women are more likely to be overweight/obese than men, even in the same household. Improved health environment (toilets, piped water, clean cooking fuel), urban jobs, television watching, and processed snacks increase the risk of overweight/obesity. Adults who are overweight/obese have a 5.6% higher risk of diabetes and a 9.7% higher risk of hypertension.Conclusions: Our results underscore the need for policy intervention to reduce the burden of obesity and NCD’s in India.

Background : Diarrheal infections remain relevant for many countries of the world. The processes of globalization, fundamental changes in nutrition and water consumption contributed to the fact that the significance of individual infection sources, etiological structure of diarrheal infections changed. Purpose of the study: on the background of the analytical study of the incidence of diarrheal infections in Ukraine under the current conditions, to determine the factors influencing epidemic situation. Methods: The reports of the Ministry of Health of Ukraine, Main Administrations of Statistics in Kharkiv, Odesa, Zaporizhia oblasts for 2011-2018 are used in the paper. Epidemiological and statistical research methods are applied. Results: The epidemic situation with diarrheal infections in Ukraine is characterized by a low incidence of typhoid fever (from 0.012 to 0.14 per 100 thousand people), shigellosis (from 1.97-6.13 per 100 thousand people), stable incidence rates without the downward trend, salmonellosis (from 17.35 till 24.1 per 100 thousand people), high incidence of diahrreal infections of specified etiology (from 115.5 to141.9 per 100 thousand people) and diahrreal infections of unspecified etiology (from 69.76 to 107.02 per 100 thousand people). The most complicated epidemic situation is observed in economically most developed regions of the country. Most diarrheal infectionsoutbreaks are connected with catering establishments 36.5 % and with children educational establishments 26.1 %. In the region with the highest shigellosis and salmonellosis incidence direct strong correlation relationships are established between the incidence and population, density, natural population movement. The oblasts with the highest diahrreal infections of specified etiology, rotaviral enteritis, diahrreal infections of unspecified etiology incidence are at least provided with water resources and have problems with provision of high-quality drinking water. There is a need to improve the system of epidemiological surveillance over diarrheal infections by extension of the indicators of microbiological study of drinking water quality in the regions of Ukraine, where high diahrreal infections of specified etiology, rotaviral enteritis, diahrreal infections of unspecified etiology incidence is registered; by increasing frequency of food item inspections in the oblasts, where mediana shigellosis and salmonellosis incidence exceeds the average one in Ukraine. Keywords: diarrheal infections, shigellosis, salmonellosis, rotaviral enteritis.

Endophytic fungi can produce many active secondary metabolites, which are important resources of natural medicines. However, there is currently little understanding of endophytic fungi at the omics levels. Calcarisporium arbuscula , an endophytic fungus from the healthy fruit of russulaceae, can produce a variety of secondary metabolites with anti-cancer, anti-nematode and antibiotic bioactivities. Comprehensive survey of the endophytic fungi genome and transcriptome will help to understand their capacity to biosynthesize secondary metabolites and lay the foundation for the development of these precious resources. In this study，we reported the high-quality genome sequence of a strain C. arbuscula NRRL 3705 based on Single Molecule Real-Time sequencing technology. The genome of this fungus is over 45 Mb in size, relatively larger than other typical filamentous fungi, and comprises 10,001 predictable genes, encoding at least 762 secretory-proteins, 386 carbohydrate-active enzymes and 177 P450 enzymes. 398 virulence factors and 228 genes related to pathogen-host interactions were also predicted in this fungus. Moreover , 65 secondary metabolite biosynthetic gene clusters were revealed, including the gene cluster for mycotoxins aurovertins. In addition, several gene clusters were predicted to produce various mycotoxins, including aflatoxin, alternariol, destruxin, citrinin and isoflavipucine. Notably, two independent gene clusters were shown possibly involved in the biosynthesis of alternariol. Furthermore, RNA-Seq assay showed that only the expression of aurovertin gene cluster is much stronger than the housekeeping genes under laboratory conditions, consistent with that aurovertins are the predominant metabolites. The gene expression of the remaining 64 gene clusters for compound backbone biosynthesis was all lower than the housekeeping genes, which might partially explain poor production of other secondary metabolites in this fungus.Our omics data along with bioinformatics analysis indicated that C. arbuscula NRRL 3705 contains a large number of biosynthetic gene clusters and has a huge potential to produce profound secondary metabolites. This work also provides the basis for development of endophytic fungi as a new resource of natural products with promising biological activities.
