Varāhamihira’s Physiognomic Omens in the Garuḍapurāṇa
Authors: Zysk Kenneth 
Published: November 2019

In this paper, I study the three chapters devoted to human physiognomy in the Garuḍapurāṇa. Two of the three come directly from Varāhamihira’s sixth-century Bṛhatsaṃhitā with the commentary (vivṛti) of the Kaśmirian Bhaṭṭotpala (fl. ca. 966 or 969 CE). I hope to make two research contributions. First, I hope to show that the date of this section of the Purāṇa, if not indeed the entire Purāṇa, cannot be before the sixth century and probably after the tenth century. Second, I will illustrate how a text in different metres was normalised into anuṣṭubh metre for ease of memory and recitation. I shall conclude with a discussion of the lessons we can learn from this kind of ancient Indian redaction process

Rationale: Riboflavin (vitamin B2) is one of the most promising agents for photodynamic therapy (PDT). However, its use is limited by the excitation in the ultraviolet (UV) and visible spectral ranges and, as a result, by a small penetration into biological tissue not exceeding a few millimeters. This problem could be solved by approaches ensuring excitation of riboflavin molecules within tumor tissues by infrared (IR) light. Upconversion nanoparticles (UCNPs) can be potentially considered as mediators able to effectively convert the exciting radiation of the near IR range, penetrating into biological tissue to a 3 cm depth, into the photoluminescence in the UV and visible spectral ranges.Aim: To evaluate the efficacy of UCNPs for IR-mediated riboflavin activation in the depth of tumor tissue during PDT. Materials and methods: The water-soluble riboflavin flavin mononucleotide (FMN, Pharmstandard-UfaVITA, Russia) was used as a photosensitizer in in vitro and in vivo experiments. The in vitro experiments were performed on human breast adenocarcinoma SK-BR-3, human glioblastoma U-87 MG, and rat glioma C6 cell lines. Lewis lung carcinoma (LLC) inoculated to hybrid BDF1 mice was used as a model to demonstrate the delivery of FMN to the tumor. UCNPs with a core/shell structure [NaYF4:Yb3+, Tm3+/NaYF4] were used for photoactivation of FMN in vivo. PDT based on FMN, UCNPs and laser radiation 975 nm (IR) was performed on mouse xenografts of human breast adenocarcinoma SKBR-3.Results: We were able to show that FMN could act as an effective in vitro photosensitizer for SK-BR-3, U-87 MG, and C6 cell lines. FMN IC50 values for glioma cells were ~30 μM, and for SK-BR-3 cell line ~50 μM (24 h incubation, irradiation 4.2 J/cm2). In the LLC model, the appropriate concentration of FMN (30 μM and above) can be achieved in the tumor as a result of systemic administration of FMN (at 2 and 24 hours after injection). The effect of PDT using near IR light for UCNP-mediated excitation of FMN was demonstrated in mouse xenografts SKBR-3, with the tumor growth inhibition of 90±5%.Conclusion: The study has demonstrated the possibility to use riboflavin (vitamin B2) as a photosensitizer for PDT. The photoexcitation of FMN via the anti-Stokes photoluminescence of UCNPs allows for implementation of the PDT technique with the near IR spectral range.
Методические аспекты прогноза и поисков крупнообъемных золоторудных месторождений на примере Енисейского кряжа
Authors: Мансуров Ринат Халитович 
Published: November 2019

Актуальность исследования обусловлена необходимостью изучения и вовлечения в производство новых крупнообъемных золоторудных месторождений, что будет способствовать образованию и долгосрочному развитию целых регионов РФ. Важным аспектом является разработка новых и совершенствование существующих методов поисков золоторудных месторождений. Целью исследования является апробация методики поисков золоторудных месторождений в сложных горно-таежных ландшафтах применительно к условиям Енисейского кряжа, в частности, в пределах малоизученной восточной части этого региона, а также выделение прогнозно-поисковых критериев и признаков вновь выявленного рудопроявления Буреминское и их сопоставление с критериями и признаками известного крупнообъемного золото-сульфидного Олимпиаднинского месторождения. Методы исследования: анализ литературных и фондовых данных; прогнозные построения на предмет выделения перспективных поисковых участков на выявление крупнообъемного золотого оруденения; разработка новых и совершенствование существующих методов и методических приемов поисков золоторудных месторождений; применение этих методов (литохимическое опробование по вторичным ореолам рассеяния разных уровней разреза элювиально-делювиальных отложений, шлиховое и сколковое (точечное) опробование) на практике; лабораторно-аналитические исследования - полуколичественный спектральный анализ на 26 элементов, химико-спектральный анализ на золото. Результаты. Вновь выявлена рудоконтролирующая зона складчато-разрывных деформаций рудопроявления Буреминское, приуроченная к зоне разрывных нарушений северо-северо-западной ориентировки, оперяющих к Ишимбинской системе разломов, в узле их сочленения с разрывами СВ направления. Комплекс шлихового и литохимического по вторичным ореолам рассеяния опробования надкоренного информативного малосмещенного горизонта элювиально-делювиальных отложений позволил выявить в пределах зоны рассланцевания несколько золотоносных минерализованных зон. Последние представляют собой зоны-залежи рассеянной вкрапленной золото-сульфидной минерализации, локализованные в интенсивно железо-магнезиально-карбонатизированных углеродсодержащих карбонат-кварц-серицитовых сланцах удерейской свиты сухопитской серии среднего рифея. Для золотой минерализации рудопроявления Буреминское выделены прогнозно-поисковые критерии и признаки. По ряду из них наиболее близким аналогом рудопроявления являются первичные вкрапленные золото-сульфидные руды Олимпиаднинского месторождения, с которым проведено сопоставление основных геологических элементов рудопроявления Буреминское.

Актуальность исследования обуславливается необходимостью повышения энергоэффективности в области использования углеводородов для комбинированной выработки химической продукции и энергоносителей с применением технологий газификации. Это даст возможность снижать издержки производства и расширять возможности газохимии. Цель исследования: определение термодинамической эффективности реакторов частичного окисления топлива, входящих в состав энергохимических установок комбинированной выработкой энергоносителей и синтез-газа. Основное внимание уделено влиянию режимных параметров на численное значение эксергетического КПД. Объект: реактор частичного окисления с набором вспомогательного оборудования, обеспечивающий получение синтез-газа. При этом учитывается системный фактор, т. е. параметры энергосистемы, в рамках которой планируется сооружение подобного типа энергохимической установки. Методы: проведение численного эксперимента с привлечением традиционных подходов к составлению эксергетического баланса теплоэнергетических установок. Также использованы разработанные ранее авторами математические модели для расчета параметров синтез-газа, образующегося в процессе переработки углеводородного сырья в проточных автотермических некаталитических реакторах. Результаты. Полученные результаты позволяют выбирать наиболее целесообразные режимные параметры работы реактора частичного окисления, входящего в состав энергохимических установок с газификацией нестабильного газового конденсата. Так, максимальные значения эксергетического КПД достигаются при использовании атмосферного воздуха без обогащения кислородом как для случая с подачей водяного пара (ŋ ex =78-83 %), так и для случая без подачи пара (ŋ ex =82-88 %). При этом некоторые варианты тепловых схем энергохимических установок с газификацией топлива в термодинамическом плане могут считаться равноэффективными, а решение по количеству подаваемого водяного пара в зону реакции должно соответствовать требованиям к синтез-газу. Выбор уровня рабочего давления в реакторе требует дополнительных исследований, поскольку очевидность применения реактора атмосферного типа на данном этапе исследований не выявлена.

Authors: Jiménez-Rivera Alexander , Montero-Carmona Wayner 
Published: November 2019

La micropropagación de raicilla se ha visto como una alternativa para suplir la necesidad de materiales para productores interesados en el cultivo. No obstante, los costos poco competitivos del cultivo de tejidos tradicional han dificultado su implementación en la producción de vitroplantas para zonas de cultivo. Con el fin de evaluar diferentes sustituciones en la composición del medio de cultivo, se realizó una comparación del crecimiento de plantas en medios con sustituciones en las sales minerales (por sales hidropónicas), Vitaminas (por tiamina o complejo B1, B6 y B12) y gelificante (por almidón de maíz).
Se observaron diferencias significativas (a=0,05) entre las características de crecimiento evaluadas (número de brotes, longitud de brotes, número de hojas y peso seco). Un análisis multivariado mostró una relación entre los medios con sustitución de sales hidropónicas, los medios con vitaminas (B1, B6 y B12) y el medio Testigo (MS); los cuales influenciaron la longitud de brotes y el número de hojas. Por su parte el medio con sustitución de almidón de maíz afectó el número de brotes y el peso seco. Esta última variable también se vio influenciada por el medio de Bajo Costo (sustitución de los tres componentes). De los tratamientos evaluados, el medio con sustitución de Tiamina fue el que presentó los rendimientos más bajos; mientras el medio de Bajo Costo los más elevados según Prueba de Hotelling - Bonferroni. El análisis de costos realizado mostró un ahorro significativo (hasta 59%) entre el medio de Bajo Costo y el tratamiento testigo (Medio MS).

Sob a égide de uma frase adaptada de um filme, o epicentro temático do presente texto reside na produção artística que motiva a inquirição teórica, revelando a génese de um processo de autor de investigação em arte. Assim, em primeiro lugar procede-se à identificação das linhas de força que emergem da panorâmica geral desse percurso artístico com mais de três décadas, desde um período inicial em que a utopia parece palpável e a que, gradualmente, se sucedem diversas realidades. Em seguida, um conjunto mais recente de obras permite maior focagem na questão da reavaliação da pintura como possibilidade artística contemporânea, cruzando a especificidade tradicional com a abertura dos limites, a liberdade e o hibridismo. Finalmente, são reveladas algumas inquietações teóricas, poéticas e políticas de um projeto recente, ainda em curso, relacionado com o filme referido.
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.

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.

Published: November 2019

Abstract
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.
Taurolidine acts on bacterial virulence factors and does not induce resistance in periodontitis-associated bacteria

Published: November 2019

Abstract
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.

Abstract
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.
