Исследовано влияние условий получения на показатели безопасности экстрактов сладкой и сброженной выжимки из винограда красных сортов – Мерло, Каберне Совиньон, Шираз, Изабелла. Для получения экстрактов использовали водопроводную воду и 1%-й водный раствор соляной кислоты. Анализ экстрактов проводили методом капиллярного электрофореза, атомной спектрометрией, химическими испытаниями. Установлено, что применение кислой среды увеличивает в экстрактах сладкой и сброженной виноградной выжимки содержание марганца на 25–39%, железа – на 33–40%, меди – на 30–60%, цинка – на 60–75%, свинца – в 2–3 раза, кадмия – в 2 раза. Проведение процесса экстракции из сладкой выжимки винограда показало уменьшение извлечения в экстракт токсичных металлов, особенно кадмия. Установленное содержание токсичных металлов и железа в экстрактах виноградной выжимки не превышало предельно допустимых концентраций для вспомогательных материалов винодельческой продукции. Наличие этанола в количестве 3,0–4,4% об., метанола 100–130 мг/дм3, суммарного содержания высших спиртов 110–220 мг/дм3, уксусного альдегида, 2-фенилэтанола, фурфурола в количестве 5–20 мг/дм3, сложных эфиров 120–240 мг/дм3 в образцах экстрактов сброженной выжимки не превышает аналогичных показателей для винодельческой продукции.

Authors: Johnson Humphrey Elliot , Kennedy Alan , Sproules Stephen , Nelson David
Published: November 2021

The use of a sodium in sodium chloride dispersion is systematically evaluated for the synthesis of nickel(0) and nickel(I) complexes from readily-prepared nickel(II) precursors. A variety of complexes with phosphine and bipyridine-type ligands were accessed, although some reactions were found to produce mixtures of nickel(0) and nickel(I), and yields were highly variable. Several new nickel(I) complexes were obtained, and these were characterised using techniques including NMR spectroscopy, EPR spectroscopy, and single crystal X-ray diffraction analysis.

Published: November 2021

Molecular optimization aims to improve the drug profile of a starting molecule. It is a fundamental problem in drug discovery but challenging due to (i) the requirement of simultaneous optimization of multiple properties and (ii) the large chemical space to explore. Recently, deep learning methods have been proposed to solve this task by mimicking the chemist's intuition in terms of matched molecular pairs (MMPs). Although MMPs is a typical and widely used strategy by medicinal chemists, it offers limited capability in terms of exploring the space of solutions. There are more options to modify a starting molecule to achieve desirable properties, e.g. one can simultaneously modify the molecule at different places including changing the scaffold. This study trains the same Transformer architecture on different datasets. These datasets consist of a set of molecular pairs which reflect different types of transformations. Beyond MMP transformation, datasets reflecting general transformations are constructed from ChEMBL based on two approaches: Tanimoto similarity (allows for multiple modifications) and scaffold matching (allows for multiple modifications but keep the scaffold constant) respectively. We investigate how the model behavior can be altered by tailoring the dataset while keeping the same model architecture. Our results show that the models trained on differently prepared datasets transform a given starting molecule in a way that it reflects the nature of the dataset used for training the model. These models could complement each other and unlock the capability for the chemists to pursue different options for improving a starting molecule.

Overriding Adolescent Refusals of Treatment
Authors: Skelton Anthony , Forsberg Lisa , Black Isra
Published: November 2021

Adolescents are routinely treated differently to adults, even when they possess similar capacities. In this article, we explore the justification for one case of differential treatment of adolescents. We attempt to make philosophical sense of the concurrent consents doctrine in law: adolescents found to have decision-making capacity have the power to consent to—and thereby, all else being equal, permit—their own medical treatment, but they lack the power always to refuse treatment and so render it impermissible. Other parties, that is, individuals who exercise parental responsibility or a court, retain the authority to consent on an adolescent’s behalf. We explore four defences of the doctrine. We reject two attempts to defend the asymmetry in the power to consent to and refuse medical treatment by reference to transitional paternalism. We then consider and reject a stage of life justification. Finally, we articulate a justification based on the distinctiveness of adolescent well-being.
Infarto agudo al miocardio sin lesiones coronarias obstructivas (MINOCA)
Authors: Soria Bajaña Satya Lucia , De La Pared Ramírez Mario Fernando , Delgado Lazo Kristel , Ortega Romero Nataly Gardenia
Published: November 2021

El infarto de miocardio con arterias coronarias no obstruidas (MINOCA, por sus siglas en inglés) ha ganado importancia en los últimos 20 años debido a la dilucidación de etiologías fisiopatológicas diferentes de las causas obstructivas del flujo coronario (obstrucción definida como estenosis < 50%). Diversos estudios han evidenciado una prevalencia que varía entre el 6% y el 25%, la cual llega a ser más alta en las mujeres (10-25%). Entre las múltiples causas de MINOCA existen diferentes grupos de alteraciones en la reactividad coronaria: las epicárdicas y las microvasculares, entre las cuales se incluyen espasmo coronario, disrupción de la placa aterosclerótica y disección coronaria, enfermedad de takotsubo, miocarditis y tromboembolia coronaria. El uso combinado de tomografía de coherencia óptica y resonancia magnética incrementa el diagnóstico del mecanismo causal en los Minoca, con un diagnóstico final en la mayoría de los casos de infarto de miocardio. El tratamiento de MINOCA se basa en pruebas limitadas y no existen ensayos controlados, aleatorizados y prospectivos. Los medicamentos (aspirina, estatinas, betabloqueantes, clopidogrel, inhibidores de la enzima convertidora de angiotensina/bloqueadores de los receptores de angiotensina) deben considerarse sobre la base del mecanismo subyacente de MINOCA en cada individuo. El enfoque general del presente trabajo es dar a conocer las características, factores de riesgo, métodos de diagnóstico y tratamiento del MINOCA. Los resultados se obtuvieron mediante el desarrollo de una investigación de tipo bibliográfica, delimitada a una metodología de revisión, que permite concluir que a pesar del creciente desarrollo de investigación en esta área, se requieren estudios que permitan obtener conocimiento más preciso del mecanismo fisiopatológico subyacente, lo que permitirá un uso racional y ajustado de la terapéutica disponible y la exploración de nuevos fármacos, tanto para el tratamiento sintomático como para la evolución pronóstica.

La punción lumbar (PL), un método utilizado tanto para fines diagnósticos como terapéuticos, y sigue siendo hoy un procedimiento ampliamente utilizado. Una de sus complicaciones más frecuentes es la cefalea post punción lumbar. Una de sus complicaciones más frecuentes es la cefalea post punción lumbar. La incidencia de esta complicación varía y puede ocurrir hasta en 40% 48 h posteriores al procedimiento. El presente artículo describe y compara diferentes literaturas sobre Cefalea post punción lumbar. Para ello, se recolecta esta información de diferentes fuentes bibliográficas adquiridas de bases de datos (SCOPUS, PubMed, Biblioteca Cochrane, Google Scholar) valorando la calidad y veracidad de la información recopilada, así como la actualidad del contenido. Los que nos indica la bibliografía consultada es que pareciera ser muy recurrente la presencia de cefalea a causa de una punción post lumbar. Sin embargo la presencia de la misma por lo general puede aparecer en mujeres en proceso de dar a luz como consecuencia de la administración de la epidural. Sin embargo estos factores no solo están asociados a la presencia de la cefalea, sino que el calibre, tamaño de la aguja e incluso la forma y dirección al momento de insertarla es determinante. En este particular estudios han confirmado que a menor calibre de la aguja tiene más probabilidades de que por la punción se genere una cefalea. El diagnostico se realiza más que todo por la clínica o sintomatología del paciente, siendo casos extremos la realización de exámenes imagenológicos a menos que la cefalea sea muy excesiva y se puedan presentar problemas neurológicos y en cuanto a lo que tiene que ver el tratamiento se recomienda tratamientos no invasivos, como reposo, hidratación y analgésicos no opioides y cafeína. Hay tratamientos invasivos como la colocación de un parche epidural.

THE BELT OF BISHOP CAESARIUS OF ARLES. BETWEEN THE "THING" AND THE "SYMBOL"
Authors:   St. Petersburg Institute of History of the Russian Academy of Sciences, Omelchenko Darya M.
Published: November 2021

The article studies the question whether bishop Caesarius of Arles (503–542) could be the owner of a leather belt with an ivory buckle from the Museum of Antique Arles. The issue is the absence of narrative sources directly proving that idea. High price of the object did not match the bishop’s ascetic reputation. Still that did not preclude that someone from the closest circle of his associates or supporters could make that gift to Caesarius. The article studies the ornament of the movable ring of the buckle and the iconographic type of the plot of the Resurrection of Christ carved on its surface. Some parts of the belt, its decoration and manufacturing techniques find parallels with various artifacts (buckles, sarcophagi, diptychs) stored in other museums or discovered during archaeological excavations in Gaul. A review of the elements of the liturgical vestments of the clergy of Late Antiquity led to the conclusion that the belt could not have a liturgical status. On the basis of narrative sources related to the life and work of Caesarius, the author makes assumptions about the possible extra-liturgical contexts of wearing such a belt. The data presented in the study make it possible not only to attribute the belt to the period of bishop Caesarius’s life, but also to consider the latter as the most likely owner of the thing.
ENGRAVING "THE TRIUMPH OF OUR LADY" IN THE PARIS BOOK OF HOURS BY GEOFFROY TORY. IS IT A PAGAN PARADE OR CHRISTIAN PANEGYRIC?
Authors:   Russian Academy of Sciences Library, Subbotina Olga V.
Published: November 2021

The article focuses on the engraving “The Triumph of Our Lady” from the Book of Hours by Geoffroy Tory, 1531, kept in the collection of the Russian National Library in St. Petersburg. That woodcut precedes the Hours of the Virgin Mary section, and complements the main row of images, most of which are related to the Mariological theme. An attempt is made to study possible sources for the rare iconography. Both Hypnerotomachia Poliphili (The dream of Poliphilus) by Aldus Manutius, Venice, 1499 and The Triumphs (I Trionfi) of Francesco Petrarch are considered. The author also takes into account the printed products of Tory himself, such as: “Champ fleury” (Flowery fields), 1529, Triumphal Entry of Eleanor of Austria, 1531. The iconography of the engraving displays the elaborately developed in Italian painting and drawing scheme of Roman triumphs of emperors and pagan gods. It also includes the visual impressions of theatrical and religious ceremonies, solemn entrances that Tory could witness. But those patterns were transformed and given a new Christian subject matter related to the glorification of the Virgin Mary. That corresponded to both the type of a prayer book (BVM) and the section the engraving preceded.

Published: November 2021

Introduction:
The literature points to several viruses associated with brain carcinogenesis, including gliomas.

Aim:
The aim of this study was to assess the presence of several viruses in gliomas and plasma from patients with brain tumor and the possible association of viral positivity with the clinical course.

Material and methods:
The study group consisted of 37 patients with gliomas who were subjected to surgery. Mean patient age was 54.59 (SD 15.85) years. The presence of viral DNA was assessed using real-time polymerase chain reaction.

Results and discussion:
We did not confirm any BK virus, John Cunningham virus, or human adenovirus-positive gliomas. The percentage of patients with gliomas positive for Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpesvirus (HHV) 6 and 7 was 18.9%, 8.1%, 2.7%, and 10.8%, respectively. We did not confirm the co-occurrence of glioma and plasma viral positivity. Fisher’s test did not reveal the influence of viral infection on the risk of death. We did not detect any differences regarding sex, WHO classification of gliomas, or the functional impairment evaluated by the Karnofsky scale index at admission to the hospital in the group of patients positive or negative for EBV, CMV, or HHV6.

Conclusions:
We cannot confirm an association of the investigated viruses with gliomas.

This paper investigated self-regulated learning skills as a predictor of students’ achievement in mathematics based on ability level. The study is prediction-design research of correlational type. The subjects were 882 SSII students from the secondary schools in Owerri Education Zone of Imo State. The researchers adopted the multi-stage but simple random sampling technique to draw the sample. Two instruments were used to collect data for this study. They are the Self-regulated Learning Questionnaire (SRLQ) and Mathematics Achievement Proforma. The validity of the instruments was ensured through experts’ suggestions and guidance. Single-administration reliability and Cronbach Alpha ensured the reliability of SRLQ (0.89). The data collected were analyzed using regression analysis and coefficient of determination at 0.05 alpha level with the aid of Statistical Package for Social Sciences (SPSS) version 20. The results of the study revealed that self-regulated learning skill predicts 6.0% and 4.3% respectively to the variance observed in high and low achieving students in mathematics. This prediction is significant as attested to by the regression analysis carried out (p < 0.05). Therefore, secondary school students should regulate their learning to increase their mathematics achievement.

Published: November 2021

Kajiannya  dilatar belakangi karena banyak siswa kelas IV yang belum bisa melaksanakan wudhu dan  tayamum dengan baik dan benar. Hal  ini  terlihat dari perolehan nilai praktek yang  belum mencapai KKM. Dari  34  siswa  dikelas  IV  hanya  18  siswa  atau  53%  yang  tuntas  KKM,  berarti  masih  ada  16  siswa  yang  belum  tuntas  pada  materi  wudhu. Sedangkan  dalam  materi  tayamum  dari  34  siswa  hanya  11  siswa  atau  33%  yang  tuntas kkm dalam melaksanakan praktek  tayamum berarti masih ada 23 siswa yang belum tuntas KKM. Peneliti  berupaya  keras  untuk  melakuka  perbaikan  dalam  pembelajaran wudhu dan tayamum melalui Penelitian Tindakan Kelas (PTK) dengan menggunakan metode  demonstrasi  melalui  dua  siklus.  Hasil  penelitian  perbaikan  pembelajaran mengalami peningkatan pada materi wudhu dari pembelajaran awal 53% meningkat menjadi 68% disiklus I dan meningkat menjadi 94% pada siklus II. Sedangkan pada materi  tayamum mengalami peningkatan dari pembelajaran awal 33% menjadi 50% disiklus I dan meningkat menjadi 94% pada siklus II. Dengan  demikian  perbaikan  pembelajaran  PAI  pada  materi  wudhu  dan tayamum menggunakan metode demonstrasi dapat meningkatkan keterampilan siswa dalam  melaksanakan  wudhu  dan  tayamum.  Sehingga  peneliti  memutuskan  untuk mengakhiri Penelitian Tindakan Kelas hanya sampai pada siklus II saja.
