Published: July 2022

ABSTRAKPenelitian ini bertujuan untuk menentukan pengaruh pH awal gel terhadap massa kristal tunggal kalsium tartrat tetrahidrat dari cangkang telur ayam dengan metode gel metasilikat. Serbuk cangkang telur ayam yang telah dikalsinasi memiliki kandungan CaO sebesar 99,53%. Serbuk CaO dari cangkang telur ayam yang direaksikan dengan asam klorida (HCl) 1,5 M menghasilkan kalsium klorida (CaCl2). Kalsium klorida selanjutnya digunakan sebagai larutan supernatan dalam sintesis kristal tunggal kalsium tartrat tetrahidrat (CaTT). Natrium silikat (Na2SiO3) yang direaksikan dengan asam tartrat (C4H6O6) membentuk gel metasilikat dengan variasi pH awal gel (pH 3,50; 4,00; 4,50; 5,00 dan 5,50). Supernatan CaCl2 berdifusi ke dalam gel dan membentuk kristal CaTT berwarna kuning bening yang tidak larut dalam akuades. pH awal gel berpengaruh pada massa kristal CaTT dimana pada pH rendah 3,50 dan 4,00 menghasilkan kristal dengan massa rata-rata 0,1722 g dan 0,2191 g, pada pH 4,50 sebesar 0,3003 g dan pada pH 5,00 dan 5,50 massa kristal yang dihasilkan berturut turut yaitu 0,2289 g dan 0,2116 g. Karakterisasi kristal hasil sintesis menggunakan XRD membuktikan bahwa kristal hasil sintesis adalah kristal CaTT tunggal dengan sistem kristal ortorombik.Kata kunci: Cangkang telur ayam, gel metasilikat, kalsium tartrat tetrahidrat ABSTRACTThis study aims to determine the effect of the initial pH of the gel on the single crystal mass of calcium tartrate tetrahydrate from chicken egg shell using the metasilicate gel method. The calcined chicken egg shell powder has a CaO content of 99.53%. CaO powder from chicken egg shells reacted with 1.5 M hydrochloric acid (HCl) produced calcium chloride (CaCl2). Calcium chloride is then used as a supernatant solution in the synthesis of single crystals of calcium tartrate tetrahydrate (CaTT). Sodium silicate (Na2SiO3) reacted with tartaric acid (C4H6O6) formed a metasilicate gel with a variation of the initial pH of the gel (pH 3.50; 4.00; 4.50; 5.00 and 5.50). The CaCl2 supernatant diffuses into the gel and forms clear yellow CaTT crystals which are insoluble in distilled water. The initial pH of the gel affected the crystal mass of CaTT where at low pH 3,50 and 4,00 produced crystals with an average mass of 0,1722 g and 0,2191 g, at pH 4,50 of 0,3003 g and at pH 5,00 and 5,50 crystal masses produced were 0,2289 g and 0,2116 g, respectively. Characterization of crystals synthesized using XRD proves that the synthesized crystals are single CaTT crystals with orthorhombic crystal systems.Keywords: Chicken egg shell, metasilicate gel, calcium tartrate tetrahydrate

Introduction. Currently, considerable attention is being given to the study of the interaction of the von Willebrand factor (vWF) and its specific regulator of metalloprotease ADAMTS13 in various clinical conditions accompanied by the development of thrombosis.Aim — to assess the change in the activity of ADAMTS13 metalloprotease and vWF factor antigen in patients with acute coronary syndrome during the first five days after the onset of an anginal attack.Patients and methods: The study included 90 patients aged 42 to 86 years (Me — 61.5 y.o.) hospitalized with a diagnosis of acute coronary syndrome. Of these, 69 were men (Me — 59 y.o.) and 21 women (Me — 63 y.o.). All patients were tested for ADAMTS13 activity, ADAMTS13 antigen, and vWF antigen. Blood samples for the study were obtained upon admission to the hospital (arterial and venous blood), as well as 24, 72 and 120 hours after hospitalization (venous blood).Results. It was found that at all points of the study, in patients without coronary artery thrombosis, the average value of the ADAMTS13 activity indicator was significantly higher compared to the group of patients with coronary artery thrombosis. At the same time, there were no statistically significant differences in the average values of the ADAMTS13 antigen between the compared groups of patients. The mean value of vWF antigen in patients with coronary artery thrombosis was significantly higher compared to that of patients without coronary artery thrombosis.Conclusion. An increase in ADAMTS13 activity was noted more often in patients with acute coronary syndrome without coronary artery thrombosis than in patients with coronary artery thrombosis, which may indicate the antithrombotic effect of ADAMTS13 metalloprotease. No differences were found in ADAMTS13 antigen levels when comparing the study groups of patients, which indicates a greater significance for the anticoagulant activity of the functional characteristics of ADAMTS13. Significantly higher levels of the vWF antigen in patients with coronary artery thrombosis were due to the response to ischemic myocardial injury and stress but were not the primary cause of the thrombotic event.

Introduction. In most cases, in patients with hereditary fibrinogen deficiency, clinical manifestations are represented by bleeding of varying intensity and localization. However, the clinical picture of hereditary fibrinogen deficiency can also be represented by thrombosis.Aim — to characterize the detected mutations in fibrinogen genes and to analyze prothrombotic factors in patients with hereditary hypofibrinogenemia and thrombosis.Materials and methods. Forty-nine patients with hereditary hypofibrinogenemia were observed, of which 46 patients had no history of thrombosis and 3 patients had a confirmed history of thrombosis. These 3 patients made up the study group.Results. Heterozygous mutations were found in all 3 patients in the fibrinogen gamma chain gene (FGG), one of them had a previously undescribed deletion g.2653_2684+211del, p.(Asp167Glufs*2), which removes 32 terminal nucleotides of the fifth exon of the FGG gene and leads to the formation of a stop codon in place of amino acid 168. In two other patients, there were missense mutations c.1140T>A, p.(Cys365Ser) and c.1114A>T, p.(Asp356Val), which can determine the thrombogenic properties of the altered protein structure of fibrinogen. Other prothrombotic factors were also identified: genetic polymorphisms of low thrombotic risk, surgery, taking combined oral contraceptives.Conclusion. Hereditary fibrinogen deficiency does not play a protective role in relation to the development of thrombosis and may cause the development of thrombosis, which is associated with its multifunctional role in the hemostasis system. The pathogenesis of thrombosis in patients with hereditary hypofibrinogenemia is multifactorial and may be associated with the characteristics of the main protein defect and the coexistence of hereditary and acquired thrombotic risk factors (surgical interventions, taking combined oral contraceptives, etc.).
Measures of social support for blood donors during the formation of the donor movement in the USSR
Authors: Serebryany R. S. , Kamelskikh D. V. 
Published: July 2022

Introduction. The period of formation of the donor community in the USSR fell on the 30–40s of the twentieth century. The first measures to organize the donor community were of a spontaneous nature. However, beginning in the 1930’s, with the support of the state and public organizations in the USSR, on the eve of the war, a mass donor community arose based on the ideology of the time and system of motivations.Aim — to reconstruct the measures of social support for blood donors, which contributed to the formation of the donor community in the USSR and to identify the role of the state in organizing the donor community in the USSR.Main findings. To conduct the study, a set of methods was used, including the study and generalization of experience based on archival sources, monographic description, and narrative analysis. A number of archival materials are introduced into scientific circulation for the first time. Decrees of the Council of People’s Commissars of the RSFSR, issued in the 30–40s of the 20th century, which formed the basis of the legal framework for organizing social support for donors, are given. This article is devoted to the emergence and development of the donor community in the USSR. A number of measures of social support for blood donors are described, which are characteristic of various stages in the development of the donor community (“attracting and retaining” donors in the 1930s, “survival” of donors at the beginning of the Great Patriotic War, and their “encouragement” at the final stage of the Great Patriotic War). Measures of social support for blood donors, which arose in the pre-war period, proved their effectiveness (attracting about 5.5 million people into the ranks of donors, from whom 1.7 million liters of blood were harvested) during the Great Patriotic War, and with some changes, maintain their relevance today.

Abstract
We measured the thermophysical properties of molten gallium oxide (Ga2O3) in a contamination-free and microgravity environment by using the electrostatic levitation furnace in the International Space Station. The density of molten Ga2O3 was obtained over a wide temperature range of 2001–2174 K including the undercooled state and found to be expressed as 5004.8–0.4478(T − T
m) (kg m−3), where T
m, the melting point, is 2066 K. Measurements of its viscosity and surface tension were also performed by using the drop oscillation method and these values were found to be 337.0 (10−3 N m−1) and 13.6 (10−3 Pa·s) at 2228 K, respectively.
Oral history: reproduction of socio-cultural reality
Authors: Denysevych Olena 
Published: July 2022

The article is an attempt to analyze the application of the method of oral history in order to actualize the understanding of the past on the example of the stories of people of Polish origin living in the Zhytomyr region. Through individual memory to recreate the collective memory, which scientists consider as a set of individual memories, which is created by the individual taking into account the influences of society and a particular social group in the process of everyday communication.
In world science, the question of what socio-historical values, knowledge, patterns of behavior, elements of folk art should be preserved and passed on to future generations to ensure effective development and to preserve social order.
Collective memory is not only the main mechanism of cultural unity of the community, but also the mechanism of "archiving" the most important components of cultural and mystical experience and the spiritual world of the nation. Collective memory is a systemic factor in "connecting" the past to the present, an important tool for updating the history of the national community. Thus, national identity is impossible without a developed collective memory as the ability to preserve and consciously reactivate previous experience.
The theory of "spiral of silence" was used as an explanation of the social behavior of the population of that time in order to save their own lives and avoid repression.

Published: July 2022

El siguiente estudio pretende señalar el aumento de la violencia hacia los adultos mayores durante el confinamiento derivado de la pandemia por COVID-19, para ello se realizó un análisis a partir de la revisión de artículos indexados y fuentes oficiales nacionales e internacionales; por medio del uso de palabras clave, se analizan los factores y escenarios de violencia en los niveles: macro social, grupal e individual y se distinguen también las afectaciones para el adulto mayor, así mismo se analizó la violencia estructural que funciona en contra de los grupos más vulnerables. Se logra identificar la presencia de la violencia a partir del confinamiento involuntario, ya que se omitieron factores de cuidado, atención y vulnerabilidades físicas y psicológicas ante la condición de aislamiento, lo cual atenta a su bienestar y se fomentan prácticas violentas que pasan desapercibidas por los órganos correspondientes de guardar la salud e integridad del adulto mayor. Las decisiones tomadas durante el confinamiento por medio de las medidas preventivas, determinó la retención y privación del movimiento del sector adulto, lo que ocasionó una omisión a los derechos de los adultos mayores, convirtiéndolos en rehenes de sus propios agresores, hogares y de la sociedad.
