Abstract
Various nuclear magnetic resonance (NMR) methods are combined to study the structure and dynamics of Li1.5Al0.5Ti1.5(PO4)3 (LATP) samples, which were obtained from sintering at various temperatures between 650 and 900 °C. 6Li, 27Al, and 31P magic angle spinning (MAS) NMR spectra show that LATP crystallites are better defined for higher calcination temperatures. Analysis of 7Li spin-lattice relaxation and line-shape changes indicates the existence of two species of lithium ions with clearly distinguishable jump dynamics, which can be attributed to crystalline and amorphous sample regions, respectively. An increase of the sintering temperature leads to higher fractions of the fast lithium species with respect to the slow one, but hardly affects the jump dynamics in either of the phases. Specifically, the fast and slow lithium ions show jumps in the nanoseconds regime near 300 and 700 K, respectively. The activation energy of the hopping motion in the LATP crystallites amounts to ca. 0.26 eV. 7Li field-gradient diffusometry reveals that the long-range ion migration is limited by the sample regions featuring slow transport. The high spatial resolution available from the high static field gradients of our setup allows the observation of the lithium ion diffusion inside the small (<100 nm) LATP crystallites, yielding a high self-diffusion coefficient of D = 2 × 10−12 m2/s at room temperature.
Rethinking the Traumatic Memory of the Holocaust in Literature (Based on Monika Schneiderman’s Work “Fałszerze pieprzu. Historia rodzinna”)
Authors: Yevchuk Uliana 
Published: October 2021

The article analyzes the attempt to reconstruct the historical memory of the Holocaust in the novel by Polish writer Monika Schneiderman “Fałszerze pieprzu. Historia rodzinna”. The writer questions the issue of Polish-Jewish relations, the responsibility and guilt of Holocaust witnesses to its victims. The author, who has a complex identity, seeks to find out for herself why her Polish family did not show enough sympathy for the suffering of Jews during World War II, including her Jewish relatives. As such indifference on the part of Poles to Holocaust victims was quite common, Monica Schneiderman tries to explain this by examining the relations between societies who lived side by side for centuries in the pre-war period, concluding that the two neighbouring nations lived in separate communities that were not open to each other.
Based on the reproduction of the history of her own family, the author seeks answers to difficult questions of universal human values – perception and understanding of others, empathy, compassion. In her works Monica Schneiderman shows the need to include these recently “closed” but extremely important topics in the public discourse.

Published: October 2021

The research focuses on the interaction of the Lithuanian and Belarusian languages in thesurroundings of Radun (Belarus, Voranava district, Lith. Rodūnia). Employing the language changemethodology, the paper presents a detailed analysis of the most prominent cases of phonetic interference oftwo – old and middle – generations of residents in both languages spoken by them.The data show that the oldest residents are expressing both languages using the Lithuanian articulatory base. Over time, the characteristic Lithuanian features begin to level: varies the pronunciation of a; in open endings, the long tense vowels i, ы are usually pronounced as é; unstressed vowels are reduced inconsistently, etc.As Lithuanian is for the middle-generation speakers, it already demonstrates essential changes, whichoccurred because they started expressing their Lithuanian using the Belarusian articulatory base. First of all, they usually lengthen stressed short vowels; they do no longer pronounce unstressed long vowels; they donot distinguish between acute – or circumflex-accented mixed i, u + R type diphthongs; the distinction between the falling and rising diphthongs ai, au, is made based on phonetic, not accentual, factors; the palatalised dental consonants t, d are replaced by the palatalised velar consonants k, g.
Regional Identity and Multiculturalism: the Baltic Germans of Latgale in the Early 20th Century Latvian Literature
Authors: Romanovska Alina 
Published: October 2021

In the studies of Latvian culture and history, there is a number of investigations dedicated to the influence of Baltic German culture on Latvian culture. Hence the Latgale region was not given due attention in this regard. The role of the Baltic Germans in this region is peculiar due to its specific history, and it is important to study how the Baltic German culture influences the multicultural identity of Latgale. A project of the Latvian Science Council The Baltic Germans of Latgale in the context of socio-ethnic relations from the 17th until the beginning of the 20th century (2020–2021) is devoted to this topic. One of the tasks of the project is the analysis of the image of the Baltic Germans in fiction. In the framework of the research, the works written in the Latvian literary language, the action of which is set in Latgale, are analysed. The focus is on fictional works about Latgale written by two authors – Antons Austriņš (1884–1934) and Ādolfs Ers (1885–1945) – in the first and second decades of the 20th century. The said writers are the first currently distinguished authors narrating in the Latvian literary language, who describe Latgale in a number of their works. Compared to other nationalities (Poles, Russians, Jews), the Baltic Germans are mentioned minimally in their works; moreover, it is a commonplace that in some cases protagonist’s belonging to German descent is not mentioned, which can only be inferred. Although the Baltic Germans belong to the Latgale past, their culture is imperceptibly and harmoniously apparent in Latgale, i.e. it is evident in the castles (castle ruins) and manors as well as in the use of Germanisms by the Baltic Germans, it has determined the location of the Latgale cities and influenced the worldview.

Authors: Chanduluru Hemanth Kumar , Sugumaran Abimanyu 
Published: October 2021

Abstract
The current study explores a design and development of the simple, fast, green and selective novel method of UPLC to quantify pitavastatin and ezetimibe simultaneously. The combined approach of Green Analytical Method with Quality by Design-based risk assessment was done using the Ishikawa fishbone diagram followed by a rotatable central composite design used for the optimization. The optimal chromatographic separation was attained through a mobile phase of 72: 28% v/v ethanol and 0.1% orthophosphoric acid (pH 3.5), with a 0.31 mL min−1 flow rate. The developed UPLC-PDA method was sensitive and specific for pitavastatin and ezetimibe, with linearity ranging from 2 to 30, 10–150 μg mL−1 with an R2 of 0.9999 and 0.9997, respectively. The forced degradation study of stability-indicating assay results shows the degradation in respective stress conditions. The developed UPLC method was validated and found to have sensible results with good linearity, accuracy and precision. Further, the greenness was evaluated using five states of art metrics like NEMI, GAPI, AES, AMGS, and AGREE metrics and found the greenest results. Based on the results we concluded that the developed UPLC method could be efficient for the simultaneous determination of pitavastatin and ezetimibe in bulk and tablet dosage.

Authors: Bilinskyi Petro 
Published: October 2021

Treatment of distal humerus fractures is a complex problem in traumatology. The result of treatment depends on the choice of fixator according to the fracture area. Objective. To improve the techno­logy of treatment in patients with complicated distal humerus fractures with fixators of small contact and multiplanar osteosynthesis and to evaluate its efficacy. Methods. 39 patients were treated for the period 2000–2020 with distal humerus nonunion (types 12-B1, 12-C1, 12-C2) and 23 patients with complicated above- and transcondylar humerus fractures (types 13-A2, 13-C1, 13-C2). Fixation of bone fragments of the distal humerus was made with device for fixation (Patent 17502 UA). It is a shaped plate with a groove on which half rings with threaded holes are stabilized. For the osteosynthesis of above- and transcondylar humerus fractures we used V-shaped plate with the possibility to regulate branch spreading width as for the condylar size (Patent 33358 UA). Autografting was performed as for necessity. Results. Plate osteosynthesis was performed mainly through anterior approach with minimal tissues traumatization. Release of radial nerve we made as for necessity. This device provides the stable fixation even in a case of short distal fragment. Device for bone fragments fixation was placed on the posterior condylar surface and lower part of the humerus through olecranon osteotomy. Osteosynthesis with suggested device is one of the options with bone autografting and can be method of choice at repeated surgery. Follow-up period was 1–2 years and later. In 60 patients we obtained good results with completed bone union. Conclusions. Suggested device can be used in cases of distal humerus nonunion. It allows to decrease the damage of surgery, to avoid many complications. Key words. Complicated fractures of the distal humerus, devices for limited-contact multiplanar osteosynthesis.

Published: October 2021

Gunshot wounds of the elbow joint are the third most common after knee and shoulder injuries. Features of the anatomical and functional structure of the elbow joint, the close location of the vascular and nervous formations, favorable conditions for the development of infection determine the severity of gunshot wounds and cause the complexity of its treatment. Objective. To evaluate the frequency and nature of the elbow joint gunshot wounds in the structure of the general combat injuries, as well as to determine the volume of medical care and direction of treatment of such injuries in the conditions of the regional hospital as a stage of care. Methods. A retrospective study included 1 809 patients (96.0 % of men, mean age (33.7 ± 0.2) years). Firearms limb injuries were detected in 1 013 (56.0 %) of all victims, of which the elbow joint — 25 (2.47 %). Mines and explosives injuries were in 22 (88 %) of the patients, bullet — in 3 (12 %). Results. Tactics of treatment of elbow joint gunshot wounds depended on the severity of the condition of the victims and the nature of concomitant traumatic injuries. In the structure of combat injury of the elbow joint the majority was combined (52 %) and multiple (40 %) injuries and was accompanied by gunshot fractures in 60 %. In patients who were in severe state, applied the tactics of Damage control in two stages. At the first stage the fractures were fixed with plaster splints or external fixation devices (EF), the wounds were not subjected to full surgical debridment (SD), but only washed with antiseptics and the visible foreign bodies were removed. In patients with soft tissue injuries wounds the primary SD was performed according to general principles, injured nerves were not restored. In the second stage, after patient is stabilized, the repeated SD of the wound was performed. After their uncomplicated healing the EF was removed and the method of fixation was changed to internal osteosyntesis. Conclusions. It is recommended to perform stabilization of intra-articular gunshot fractures of the elbow joint with EF and after uncomplicated wound healing go to the internal osteosynthesis. Key words. Elbow joint, gunshot wounds, treatment.
Comparative analysis of weight-bearing function of lower extremities in children with recurrences of congenital equinovarus clubfoot after surgical treatment by «traditional» methods and Ponseti method

Published: October 2021

Congenital equinovarus clubfoot (EVC) is the second most common congenital anomaly of the musculoskeletal system in children and one of the most common causes of childhood disability in Ukraine. The frequency of EVC reaches 1–3 cases per 1 000 newborns (35–40 % of all foot deformities). Objective. To determine the features of the children ability with EVC recurrences, before and after surgical treatment by «traditional» methods and Ponseti method. Methods. Biomechanical examinations of 65 children with EVC recurrences were performed. They were divided into two groups: group I (33 patients) — treated by «traditional» methods, which provided initial surgery, in order to completely correct all components of the deformity; group II (32 patients) — treatment by Ponseti method. Weight-bearing function was studied for all patients, before treatment, after 6 and 12 months after surgery, with statography. Results. It was determined that the standing parameters in the groups were not statistically different. After 6 months after the treatment, according to the statograms, the weight-bearing displacement remained, under the conditions of two weight-bearing standing towards the contralateral limb, in both groups of patients. In group I, after treatment, this parameter did not change (p = 0.924), and in group II it decreased by (2.7 ± 4.7) % (p = 0.013). Weight-bearing on the operated limb in both groups, in 12 months from surgery increased by 45 %. Conclusions. In patients, after treatment of EVC recurrences by Ponseti method, the weight-bearing function indicators, in the case of two weight-bearing standing, changed statistically significant. During the recovery process, when patients began to load the operated foot, a slight deterioration of standing parameters was observed in patients of group I in 6 months from surgery. In patients of group II, a complete restoration of statographic parameters occurred earlier, in 6 months, a normalization of weight-bearing and stability was observed. Thus, it can be argued that the use of Ponseti method in the complex treatment of EVC allows to restore the ability of weight bearing much earlier than with the «traditional» method. Key words. Congenital talipes equinovarus, children, Ponseti method, statography.
Molecular hydrogen as a possible therapeutic factor in complex rehabilitation therapy in patients with muscular skeletal disorders (literature review)
Authors: Makolinets Vasyl , Grashenkova Tamara , Moseichuk Volodymyr , Makolinets Kyrylo , Moseichuk Vladyslav 
Published: October 2021

The paper presents an analysis of foreign scientific and medical data on the therapeutic factor — molecular hydrogen. The effectiveness of its application in the complex therapy of many diseases is revealed. The effect is achieved due to the small size of the mo­lecule, which passes through biological membranes and inhibits dangerous free radicals in the mitochondria, as well as in the nuc­leus, which reduces the possibility of DNA damaging. Molecular hydrogen neutralizes oxidants in the brain due to its ability to cross the blood-brain barrier. It normalizes the functions and metabolic processes in the body and, as an antioxidant, is selective: it does not affect the useful free radicals involved in important metabo­lic processes and selectively eliminates only the most dangerous oxidants — hydroxyl radicals. Interacting with them, hydrogen converts them into water molecules without the formation of by-products and chain reactions. Unlike other known antioxidants, molecular hydrogen does not disrupt normal metabolism, does not cause negative changes in cells, activates the body’s own anti­oxidant systems. The possibility and expediency of the use of molecular hydrogen in the case of pathology of the musculoskeletal system has been confirmed. The peculiarities of its effect on bone and cartilage tissue in the experiment are shown. It has been determined that the use of molecular hydrogen is a new pharmacological strategy aimed at the selective removal of ONOO—, and can be an effective method in the treatment of joint diseases. Because cartilage receives nutrients through a diffusion-loading mechanism, and molecular hydrogen penetrates rapidly into tissues, it can be useful for the prevention of diseases of joints of degenerative origin. It reduces oxidative stress and slows down the reduction of matrix proteins and inhibition of proteinase degradation. Its effectiveness has been proven after injuries to the spinal cord, muscles and tendons, comorbid diseases such as hypertension, coronary heart disease, diabetes and metabolic syndrome. Key words. Molecular hydrogen, hydrogen water, hydrogen inhalations, joint diseases, consequences of musculoskeletal injuries, comorbid pathology.
