Authors: Viogenta Pratika , Susanti Laila , Megasari Latifah
Published: January 2023

The urgency of finding novel sources of active compounds to overcome infectious diseases is encouraged. Morel berry (Physalis angulata L.) is a traditional herbal plant that can be used as an antimicrobial because of its unique chemical content. This study aims to find compounds that have antibacterial activity from the chloroform fraction of morel berry roots. This study used the Kirby-Bauer method with concentrations of 20%, 40%, 60%, 80%, and 100% against Staphylococcus epidermidis and Pseudomonas aeruginosa bacteria. Determination of antibacterial compounds and their functional groups was performed using thin-layer chromatography (TLC) technique and reagent spray test, TLC-Bioautography and Fourier transforms infrared (FTIR) studies. The chloroform fraction of morel berry showed a zone of inhibition with the highest diameter of 11.50 and 12.00 mm against S. epidermidis and P. aeruginosa, respectively. Phytochemical screening revealed the presence of alkaloids, flavonoids, tannins, and saponins in the chloroform fraction. The relative retention stain of 0.54 on the TLC plate inhibited the growth of the two tested bacteria and indicated the presence of functional groups O-H phenol, C-H aliphatic, C=O ester, C=C aromatic, C-OH alcohol, and C-H aromatic. This study found that tannins in the roots of morel berries could be used as a natural antibacterial agent to treat S. epidermidis and P. aeruginosa.

In the modern world, with the weakening of the trend of globalization, the trend of regionalization is of fundamental importance for maintaining not only the economic, but also the socio-political order in individual states. Most often it is understood as progress in the field of regional integration. However, this does not exhaust its positive potential. It also manifests itself in the deepening of the processes of interconnected development of both territories and spheres of activity, manifesting in them its transformative, integrative nature. One of the most significant areas for the future, where serious integrative changes are observed, has become the field of education. It is education that can give a more holistic character to integration in the post-Soviet space.

Authors: Ivanova Alla E. , Semyonova Victoria G.
Published: January 2023

The article deals with the issues of assessing premature mortality using potential demographic methods, which allows taking into account not only the number of death events, but also the age of the deceased.
This approach, applied by the authors to assessing the trends and structure of causes of death during the pandemic in Moscow and Russia, demonstrated an overestimation of the significance of causes specific to young ages. As part of the discussion, using the example of a comparative characteristic of potential life losses in the United States and other economically developed countries, it is shown how the factor of a younger mortality structure in the United States due to a pandemic caused significantly higher not only demographic, but also social losses.

El limón persa, es un cultivo que ha ganado suma importancia en el campo mexicano, gracias a las condiciones medioambientales que favorecen el desarrollo de esta especie. Actualmente los estados con mayor producción son: Veracruz, Michoacán, Oaxaca y Colima que en conjunto aportan a nivel nacional el 75% de la producción. Hoy en día México ocupa el segundo lugar a nivel mundial en la producción de la variedad de limón persa en donde un 70% del total se destina a mercado nacional y el resto al mercado de exportación principalmente a EU. En el cultivo de limón persa por ser un cultivo permanente, se encuentra un elevado grupo de organismos entre benéficos y parásitos o plagas. Es importante determinar cuáles son las especies de insectos y ácaros que son plagas, para conocer su comportamiento e interacción con las especies benéficas evitando así, romper el equilibrio existente en el cultivo. La importancia de los ácaros en la especie Citrus latifolia L., puede comprender hasta un 20% de las plagas de mayor incidencia económica en diferentes cultivos incluyendo al limón persa, esta importancia aumenta debido a que la “araña roja” ataca directamente en la calidad del fruto lo que ocasiona pérdidas mayores en huertos de exportación.

Bailarines. Identidades disruptivas en construcción
Authors: Tortajada Quiroz Andrea Margarita
Published: January 2023

En Occidente, la danza escénica es una práctica considerada femenina y contraria a las masculinidades hegemónicas. Por tal razón, los bailarines varones se ven obligados a superar obstáculos culturales, políticos, económicos y sociales para realizar su labor, y han construido y representado masculinidades alternativas. De esta manera, en la arena social, las luchas no se reducen a “lo femenino” y “lo masculino” enfrentados sino que, como se estudia en este texto, también a las masculinidades diversas que buscan expresarse. Muchas veces, incluso, el término de masculinidades ni siquiera se aproxima a la identidad con la que se reconocen las personas consideradas biológica y socialmente hombres, pues plantean géneros alternativos y disidentes que rompen con el binarismo generalizado, y los exploran y representan en una gran diversidad de formas dancísticas. Aquí se retoman testimonios de creadores escénicos que viven ese proceso artístico y político.
THE PICTORIAL TREATMENT OF THE 18 TH CENTURY PAINTED LAMBRIGGIO IN THE ALCOVA ROOM OF PALAZZO CHIABLESE: METHODOLOGICAL APPROACH, TECHNICAL SOLUTIONS AND RETOUCHING
Authors: Gatti Alessandro , Russo Danilea , Capezio Roberta , Piccirillo Anna , Caldera Massimiliano , Manchinu Paola
Published: January 2023

This paper illustrates the results of the diagnostic campaign, the problems that emerged and the choices made during the 2019 intervention in the Alcova room of Palazzo Chiablese, paying particular attention to the phase of aesthetic restitution of the polychrome wooden lambriggio with panels dated to the second half of the 18th century. The radical changes in the intended use of the environment during the 19th century, associated with the destruction that occurred during WW2, left indelible wounds on the painted artefacts. In particular, the panels have undergone repeated treatments such as to conceal, in some cases, the 18th century paintings, creating a strong visual discontinuity. The pictorial activity included diversified technical solutions, modulated according to the specific problems encountered: small retouching alternated with extensive reconstructions based on historical photographic documentation and on direct comparison with the decorative elements of the most preserved panels. In compliance with the conservative history of the artefacts an overall recovery project was developed aimed at the search for a new aesthetic unit capable of coherently communicating with the remaining fixed furniture and mobile environment.
Smart Heritage: an easy method for matching colors
Authors: Vatteroni Carolina
Published: January 2023

Historic buildings and architectural surfaces are a significant part of the European heritage.In the field of preservation and conservation of historic facades – especially for those of buildings that are still in use - restorers frequently face the task of faithfully repurpose from a chromatic point of view surfaces and paintings, often having small patches of original color as the only reference.This step is often carried out by visual assessment by a restorer proficient in the field of colorant formulation and with in-depth knowledge of the behavior of colorants in a specific material: the process involves making a series of samples that are tested on the surface to be treated, in order to identify the most suitable.Nevertheless, such a procedure is strictly related to the sensitivity of the conservator.The series of samples produced can easily be subject to phenomena of observer metamerism and conditional match: in fact, it is possible that a set of samples that appear to match under a defined set of viewing conditions, such as light source or viewing angle, no longer match if those conditions change.Since restoration is first and foremost a science, the restorer is provided by the market with effective and specific color measurement devices that are able to capture, measure and quantify the color of a surface, providing reliable data: -in order of increasing sophistication- densitometers, colorimeters and spectrophotometers.Unfortunately, on a restoration site and scaffolding the restorer does not always have the opportunity to use such sophisticated field-portable: as such equipment is often designed for other purposes, its use in built heritage conservation usually necessitates testing and careful calibration on order to ensure accurate data.Compromises must be made: the aim of this paper is to identify an intermediate solution, which would be more effective than visual assessment, easy to perform, and significantly less expensive than portable spectrophotometers.How this will be achieved? The tool I tested for this purpose is X-Rite's Color Checker, a target specifically designed for photography and video production that is able to compare, measure and analyze differences in color reproduction in any color rendition system.I used the Color Checker target and software to compare original paintings with samples reproduced by visual assessment, in order to verify their spectral match, which means the two colors have the same color coordinates and appear identical regardless of illuminant or observer.Then, I tested my data by comparing them with those obtained by specifically designed equipment.The results show that this method is able to provide relevant information on color matching, it is quick and easy to perform and definitely affordable, and it could represent a smart alternative for built heritage conservation.
RETOUCHES WITH HISTORY – CONSERVATION OF THE SACRED HEART OF JESUS BY ADOLF HERMAN DUSZEK AND ITS AUTHORIAL POST-WWII RESTORATION
Authors: Śwituszak Paula Karina , -Szewczyk Alina Tomaszewska
Published: January 2023

WWII left a great proportion of cultural heritage in Middle-Eastern Europe damaged. In the immediate aftermath of the war, there was neither necessary expertise, manpower nor resources to deal with such complex and total conservational challenges. Artists and craftsmen took to preserving and repairing the most darling objects of local heritage, leaving to us not only their original works, but also visible marks of the struggle to preserve them. Today, we are facing the task to preserve the multilinear story hidden behind those objects - their original body, wounds, and bandages, showing both the art of creation as well as the art of restoration to next generations. A great example of such a conservation effort is the story of The Sacred Heart of Jesus, painted by Adolf Herman Duszek in 1924 and restored by him after the war, in 1950. Over 70 years later, the painting required another intervention – mainly because of the bad state of preservation of the paint layer. The main challenge of this restoration was to find the balance between leaving the visible traces of the history of the object, the conservation ethics as well as the aesthetics and expectations of the recent owners. As it turns out, the impact of a private context is a significant aspect during the formation of the conservation programme. This paper discusses the need for compromises which had to be reached during the conservation of this particular painting.

Authors: Vuga Martina
Published: January 2023

This paper presents results of the preliminary examination and conservation-restoration treatment of polychrome wooden sculpture, Madonna and Child, dated around 1520 from the National Gallery of Slovenia. Extensive areas of paint loss, discoloration of old retouches and darkened coating on gildings disrupted the sculpture’s visual unity and balance. Overpaints have progressively and significantly changed its appearance. Prior to the intervention we conducted detailed technical examination. Treatment included surface cleaning and partial removal of materials. Decisions, methods, and materials regarding aesthetic reintegration are pointed out: various approaches used on different surfaces, of which faces, and other parts of the skin, received a comprehensive “skin care”.

Published: January 2023

The glazed ceramic pitcher no. N11519 from the National Museum of Slovenia collection presents empirical research and approaches to conserving damaged paintings by testing conservation materials and various reintegration techniques. Studies of specific pigmented retouching paints describe the retouching practice of glaze-like retouching paints. They have been a part of the diploma thesis entitled Ways of reintegration the missing polychrome painting on ceramic pitcher at the Academy of Fine Arts and Design, University of Ljubljana, majoring in Conservation and Restoration of Fine Arts. The reintegration assessment intends to present multilayered paint effects on chromatic reintegration of a large area of reconstructed painting on a ceramic pitcher. A silicone mold was made in the selected area of an extensive paint loss for reintegration samples, from which gypsum casting mock-ups were formed. The practical determination of the chromatic reintegration was to simulate the stratigraphy of the paint layer and the in-glaze method of decorating the pitcher: a white underglaze over which a polychrome painting with overglaze was applied. The practical goal was to get close to the original painting's color, structure, and texture with differing application modes in lines, dots, liquid strokes, and surface smoothing. The chromatic reintegration tests of a glaze painting were perceived with varied and comminated approaches to applying retouching paint media to gypsum mock-ups. This can be achieved by meticulous scrutiny to review and evaluation a medium in the appropriate solvent. The mock-up assessments showed that the most suitable for the glazed pitcher is chromatic reintegration with dotted hatched, using the retouching colors with urea-aldehyde resin Laropal® A 81. The researched methods and the technique of chromatic reintegration on a ceramic pitcher were presented in the exhibition In Good Hands: 60 Years of the Department of Conservation and Restoration of the National Museum of Slovenia

The painting, a large-scale oil on canvas (256 x 325 cm), was one of a number of pictures restored in the late 1960s by a team of conservators from the Istituto Centrale del Restauro in Rome, who came to Dublin during the establishment of the first conservation studio at the Gallery. The visiting restorers brought novel ideas and materials with them from the Istituto that would shape the Irish approach to conservation for decades to come. The prevailing ethos at the time in Italy was based on a minimal intervention approach with the use of novel, synthetic materials that had not yet been introduced to the collection of the National Gallery of Ireland.  The painting, after treatment by the Istituto team, recorded material evidence of a particular moment in the development of conservation in Italy and Ireland. Large areas of historic loss and damage across the surface of the painting had been reintegrated by the Italian restorers with the application of retouchings in the tratteggio style, also known as rigatino, using a Paraloid-based medium. In some cases, portraits and other significant details in the image were fully reconstructed by the retouchings. Underlying instability required the removal of some of these retouchings during the most recent treatment, but others could be retained if desired. With the help of archival images and documentation, a decision-making model was developed to evaluate the quality and historic value of these retouchings and to determine which to preserve, which to modify and which to remove. Reduction of retouchings often necessitates replacement, and the partial preservation of the historic retouchings brought further factors to bear on the decision-making model for the chromatic reintegration of the painting. A return to the tratteggio technique was chosen for the larger instances of loss compensation in the treatment, albeit with a finer hatching so that the newer reintegration remains distinguishable from the historic one. This was complemented with a pointillist technique over textured fillings for smaller and shallower losses.  Furthermore, where blistering and heat damage in the paint layers resulted in uneven topography, a third auxiliary technique was used. The desired texture was found when testing Paraloid-based gels on a mock-up and applied to bring continuity the surface texture in these areas of the painting. With this approach we intend to meet the conservation needs of the object, restore the legibility of the image and retain the evidence of the historic intervention of this founding team of Italian restorers at the National Gallery of Ireland.
With a little help of my friends. A hopeful educational methodology on retouching for conservation-restoration students on wooden sculpture.
Authors: Tonini Francesca
Published: January 2023

Is it possible to mix and match the theoretical foundations of Cesare Brandi - internationally recognized - with the new theories of Muñoz Viñas  for a new ethics of restoration, taking into account the suggestions of Paul Philippot, who was the first to deal with the restoration of wooden sculpture? For educational purposes in restoration schools, is not easy to cover all these aspects of retouching, but it is important to find a method that allows students to acquire a solid foundation, and then to deepen the different aspects of the question, hopefully simple but at the same time effective. The Author develops a proposal based on three basic cornerstones: 1. familiarity with the techniques of execution of the work of art and the materials of which it is composed (study of technical art history, and laboratory practice from painting to gilding); 2. study of the basic principles of the restoration theory; 3. practical experiments with the different techniques of pictorial integration (tratteggio, selezione cromatica, selezione effetto oro, dots, mimetic retouching), of the different retouching materials (watercolors, tempera, varnish colors, micaceous), and with protective coatings. In all situations the basic theoretical principles are: 1. recognizability: the pictorial restoration must always be easily recognizable (also using modern technologies); 2. reversibility, i.e. the retouching must be easily reversible without endangering the original work. Thus, the proposed methodology will be a useful tool to contribute and work on the wooden cultural heritage by including not only tangible aspects but also emotional, ideological and above all identity meanings.

Purpose

Congenital lung malformations (CLMs) consist of a variety of pulmonary development disorders. In the CLM approach, computed tomography (CT) is considered the gold standard imaging technique due to the high-resolution for the lung parenchyma evaluation, the study of the vascular system after contrast injection, and the multiplanar reconstructions. In the paediatric population CT is considered too invasive due to ionizing radiation and the use of contrast agent. Therefore, the indications for the use of magnetic resonance imaging (MRI) are increasing. The aim of our study is to compare retrospectively MRI and CT in the evaluation of CLMs, to reduce or avoid the use of contrast-enhanced CT in the paediatric population.

Material and methods

We retrospectively evaluated 22 paediatric patients with prenatal diagnosis of CLMs. All the patients underwent postnatal MRI in the first 2 weeks of life (except for a patient) and pre-surgery contrast-enhanced CT. A total of 7 blinded radiologists divided into 3 different groups independently reviewed each MRI and CT examination. Sensitivity and specificity of radiologists with different years of experience on the field, as well as of MRI findings regarding every pathology, were evaluated using a ROC curve. The interobserver agreement regarding the MRI findings was also measured.

Results

Analysing the ROC curves, we observed that MRI provided a satisfactory accuracy for diagnosing most congenital pulmonary diseases.

Conclusions

Our study showed that MRI without contrast agent allows us to reach a CLM diagnosis in good agreement with contrast-enhanced CT, which is considered the gold standard imaging technique.
14-3-3η protein is associated with disease activity and osteoporosis in patients with rheumatoid arthritis
Authors: Adel Yasmin , Sadeq Yousra
Published: January 2023

Objectives

This study was designed to explore the potential association of serum 14-3-3η protein level with disease activity and bone mineral density (BMD) in Egyptian patients with rheumatoid arthritis (RA). Patients were recruited from the outpatient clinic at Mansoura University Hospital.

Material and methods

One hundred eighty-eight patients with RA and 192 matched controls were enrolled. The rheumatoid arthritis activity parameters were evaluated in RA patients. Bone mineral density was measured. Serum levels of 14-3-3η protein and IL-6 were estimated for all participants by enzyme-linked immunosorbent assays (ELISA).

Results

Rheumatoid arthritis patients had a significantly higher median serum 14-3-3η protein level compared to matched controls (p ≤ 0.05). Serum level of 14-3-3η protein was significantly correlated with DAS28–ESR (p ≤ 0.05) and serum IL-6 level (p ≤ 0.05). The rheumatoid arthritis-osteoporosis group had significantly higher serum 14-3-3η protein than the RA-osteopenia group and RA-control group. Similarly, the difference of the serum 14-3-3η protein between the RA-osteopenia group and the RA-control group was significant. In the linear regression analysis, the strongest factors that were associated with BMD in RA patients were the serum level of 14-3-3η protein (p ≤ 0.05), IL-6
(p ≤ 0.05) and DAS28–ESR (p ≤ 0.05).

Conclusions

Serum level of 14-3-3η protein was significantly elevated in RA patients compared to controls and is significantly correlated with parameters of activity disease. The RA-osteoporosis group had significantly higher serum 14-3-3η protein than the RA-osteopenia group and RA-control group. Serum 14-3-3η protein can be a promising biomarker to reflect RA activity and predict presence of osteoporosis in RA patients.
Cardiovascular lesions in giant cell arteritis
Authors: Dzhus Marta , Mostbauer Halyna
Published: January 2023

Introduction

Giant cell arteritis (GCA) is a systemic vasculitis that affects large vessels. Cardiovascular complications that develop with GCA have high morbidity and can be fatal. The aim of this work was to discuss epidemiology, clinical picture, etiopathology and risk of development of cardiovascular complications in GCA.

Material and Methods

A literature review was performed for 2002 to 2021 using PubMed and Medline scientific search databases. The following keywords were used to search academic journal databases: “giant cell arteritis”, “heart attack”, “cardiovascular system”, “aortic aneurysm”, “coronary heart disease”, “aortic dissection”, “myocardium” and “stroke”. Articles written in languages, other than English, were excluded.

Results

The analysis of studies showed an increased risk of an aneurysm, aortic dissection, coronary heart disease, cerebrovascular events, and peripheral artery disease in patients with GCA. This was not surprising as it has been shown that, cardiovascular complications worsens the prognosis in GCA. According to the results of observations and cited studies the most significant risk of cardiovascular complications was observed in the first year following the diagnosis of GCA.

Conclusions

Patients with GCA have an increased risk of cardiovascular disease, but research data/findings are somewhat conflicting, and there is limited information/knowledge on how to treat the patients. Awareness of the risk of cardiovascular disease in GCA is essential, and monitoring these potentially fatal consequences is mandatory in patients with GCA. It is critical to be aware of the danger of cardiovascular illness in GCA patients and to keep track of these potentially deadly outcomes.
The use of orthoses in the treatment of carpal tunnel syndrome. A review of the literature from the last 10 years
Authors: Georgiew Filip , Florek Jakub , Janowiec Sebastian , Florek Paweł
Published: January 2023

Introduction

A review of the literature from the last 10 years quite clearly shows that immobilization of the wrist in the splint (orthosis) is the most effective, initial method of conservative treatment of carpal tunnel syndrome (CTS). The particular advantages of the described method of treatment are: availability, low cost, good patient tolerance, simplicity and minimal incidence of complications.
The aim of this study was to try to define the criteria of proceeding with the selection of the type of orthosis and the duration of its use depending on the clinical condition and the patient’s expectations.

Material and Methods

The PubMed electronic database was searched for appropriately selected studies published between 2012 and 2022. The search strategy used was based on the following keywords: carpal tunnel syndrome, immobilization, orthosis, conservative treatment. The authors also searched the cited literature on relevant research and review papers on potentially relevant topics related to conservative treatment of the CTS.

Conclusions

Immobilization in an orthosis gives therapeutic effects in all patients, regardless of the stage of the carpal tunnel syndrome.
Most often the orthosis is only used at night for several weeks. During the exacerbation of symptoms, it can also be used during the day during activities that increase symptoms.
In practice, it is recommended to wear a splint that immobilizes the wrist in a neutral position or slightly extended at 0–15 degrees (most often 0–5 degrees).
A splint immobilizing the wrist and the 2–5 metacarpophalangeal joints are recommended for patients with positive Berger test results.
There are no statistically significant differences in the treatment results between individual and traditional orthoses.
No statistically significant differences were observed in the treatment effects between rigid and soft orthoses.
