State of cellular and humoral systemic immunity in women of reproductive age under the development of proliferative processes in the endometry of the uterus and breast glands
Authors: Shapoval Yuliia 
Published: June 2022

The immune system plays an important role in the pathogenesis of endometrial hyperplasia (EH) and benign breast tumors, as in the body of women this system interacts closely with the reproductive system. Due to the fact that the transformation of endometrial cells and mammary glands is controlled by the immune system, it is important to study the redistribution of components of cellular and humoral immune components in women with combined pathology.
The aim of the study was to study the state of cellular and humoral parts of the immune system in women of reproductive age, patients with endometrial hyperplasia and benign breast tumors.
Materials and methods. Studies of the state of the immune cell were performed in peripheral blood to determine the subpopulation composition of blood lymphocytes using monoclonal antibodies to antigens CD3 + (total number of T lymphocytes), CD4 + (T-helpers), CD8 + (T-suppressors), CD16 + (NK cells), CD19 + (B-lymphocytes). Indicators of humoral immunity - immunoglobulins (Ig) of classes A, M and G were determined using monospecific sera against these immunoglobulins.
Results of the research. There was a decrease in the mean values of T-lymphocytes, T-suppressors, T-helpers and B-lymphocytes with a simultaneous increase in NK cells in the peripheral blood in patients with GE and mastopathy compared with the control group. There was a decrease in the immunoregulatory index - the ratio of CD4 + / CD8 +. An increase in the content of Ig G and a decrease in the levels of Ig M and Ig A in the groups of patients with GE and in the combination of GE and mastopathy in comparison with healthy women is shown.
Conclusions. Immunological homeostasis, which is characterized by changes in cellular and humoral immunity at the systemic level, is involved in the violation of reproductive function in women with hormonal imbalance, which leads to the development of GE and mastopathy

The research object in the work is the printed circuit boards (PCB) Production technological process using the additive technology of photopolymer 3D printing. The existing problem is that the manufacturing process of single-sided and double-sided PCBs, simple in technology, from the third to the fifth accuracy class, requires the use of a large amount of consumables and technological equipment. In turn, this affects the cost of the product. The research subject is models and methods for manufacturing PCB using photopolymer 3D printing.
In order to reduce the cost of materials: film or aerosol photoresist, as well as reduce the number of technological operations, applying photoresist and for the manufacture of PCBs stencils, it is proposed to use photopolymer 3D printing technologies for the manufacture of PCBs. The paper analyzes the costs of Plexiwire Resin Basic Orange Transparen photopolymer resin for the manufacture of single-sided PCBs and calculates the cost of the consumable (resin) compared to the costs of dry film photoresist. 60 % cost of consumables (photopolymer resin) compared to dry film photoresist for making single-sided PCBs. The work is aimed at determining the dependence of the geometric dimensions of the PСВs topology and the consumption of photopolymer resin on the technological parameters of photopolymer exposure. A regression correlation model of the dependence of resin consumption on exposure parameters has been developed and correlation coefficients have been calculated. It has been established that with an increase in the exposure time of the photopolymer resin, the consumption of the photopolymer resin increases and the deviation of the geometric dimensions of the PCBs topology increases, which in turn negatively affects the quality of the product. Therefore, using the obtained regression model, it is possible to calculate the influence of parameters on the PCB topology and reduce the deviation of conductor sizes and resin consumption.
Effect of vacuum drying the insulation pressboard on partial discharge characteristics under ripple voltage conditions

Published: June 2022

The object of the research is partial discharges arising in a sample of the insulation pressboard. In most modern high-voltage direct current transmission schemes based on voltage-source converters six-pulse or twelve-pulse converters are used. The signal waveform on the direct current voltage side of a high-voltage direct current transmission is not pure direct current voltage and it has alternating current component. Since the partial discharge activity under distorted voltage is much different than that under pure direct current voltage, voltage ripples and voltage harmonics are the subject of various studies.
This article examines the effect of vacuum drying the insulation pressboard on partial discharge characteristics at direct voltage ripples. The insulation pressboard was dried in a vacuum chamber with a residual pressure of 1 mm Hg.
Among all the characteristics of a partial discharge, the main focus has been on the apparent charge of a partial discharge. The greater is the apparent charge value, the stronger is the destructive effect on high-voltage insulation. It was shown that drying the insulation in a vacuum chamber has the greatest effect on reducing the apparent charge of a partial discharge at direct current voltage than at alternating current voltage. After drying the insulation in a vacuum chamber, the amplitude of the partial discharge pulses was decreased by 99.3 % at direct current voltage in comparison with the moistened sample. After vacuum drying, at DC voltage, rare and very low magnitude partial discharges were recorded.
The conducted research contributes to the development of methods for partial discharge detection under non-standard voltage conditions.

Published: June 2022

The object of research is the development of applying a consistency to a vertical surface using an automated device. One of the most problematic places is the poor quality of work at height and the danger associated with the life of workers. Currently, there is only a manual and semi-mechanized method of applying the mixture to a vertical surface. When applying plaster to a vertical surface inside a building, some countries use a plastering robot. In this case, the work is done with high quality and is serviced by two workers. Therefore, when studying this issue, the authors decided to develop a device with which it is possible to perform work on applying to a vertical surface from the outside of the building with high quality.
In the course of the study, technological maps were used, on the basis of which estimates were developed, which showed that the introduction of new technologies makes it possible to obtain up to 20 % cost savings on works, equipment and mechanisms. An economic effect was obtained from the developed technology. This is due to the fact that the proposed technology makes it possible to reduce the cost of work using the developed equipment, since the equipment serves 3 workers, namely 1 operator and 2 workers servicing this equipment. The proposed equipment has a number of features that make it possible to additionally mix the mixture at the outlet, edit the supply of the mixture, apply the required thickness evenly, in particular, control the quality of work. This makes it possible to choose the inclination angle, the thickness of the mixture and obtain indicators of the strength of the mixture and the number of losses. Compared to similar known methods, the mixture is fed automatically, which provides advantages such as quality control, safety precautions and reduces the risk of loss of life.

AbstractObjective. Epilepsy surgery can potentially cure drug‐resistant epilepsy, but careful presurgical evaluation is vital to select patients who will profit from such an intervention. Many epilepsy surgery programs offer extensive presurgical evaluation including several days of video‐EEG monitoring. Non‐lesional epilepsy cases are rare among epilepsy surgery patients. We set up a lesionorientated paediatric epilepsy surgery program for patients with clearly localized lesions with limited presurgical diagnostics, in particular, with a maximum of 48 hours of non‐invasive EEG monitoring that did not necessarily include ictal EEGs.Methods. We retrospectively evaluated the outcome of patients who were operated on within our epilepsy surgery program with respect to seizure freedom.Results. Fifty‐two children and adolescents with MRI lesions at a mean age of 8.27 ± 4.83 years (range: 0.17‐18.87) underwent a resective procedure. The most frequent surgery was a hemispherotomy. Overall seizure freedom was 81.8% after 12 months and 85.6% after a median observation period of 20.45 months. Seizure frequency was reduced >50% in all other patients. Preoperative recording of an ictal EEG on the side of surgery had no effect on postoperative seizure outcome (p= 0.697), nor did recording of epileptiform discharges on the ipsilateral (p= 0.538) and contralateral side (p= 0.147).Significance. Our findings highlight the high success rate using a lesionorientated epilepsy surgical approach with reduced presurgical video‐EEG monitoring in the paediatric epilepsy population. Our data show that it is possible to reduce the complex pre‐surgical work‐up for epilepsy in children and adolescents by asking the basic question: “Is there any reason why the lesion should not be resected”.

A cigány/roma közösségek kutatásának hazai irányai és legismertebb eredményei
Authors: Láczay Magdolna 
Published: June 2022

A magyar többségi társadalomban félévezrede ismertek a cigány közösségek. A források azonban szegényesek, és csak az életük néhány területére adnak információt. A szórványosan, kis létszámban érkező népcsoport definiálására akkor vállalkozott a tudomány néhány tudósa, amikor létszámuk jelentősen megnőtt. A 20. század második felében előbb a levéltárosok és a néprajztudósok kutatták, honnan származnak, van-e közös történelmük, honnan ered a nevük, milyen sajátos jellemzők alakítják az életformájukat, nyelvüket, kultúrájukat, hiedelemvilágukat. Eredményeik alapján kisebbségként definiálták őket, de mára Európában már 10-12 millióra becsülik a létszámukat. A cigány/roma történelemnek vannak naiv kutatói és szószólói, akik a régmúlt dicsőségét és a meghurcoltatásokat vélik megtalálni, de a tudományos kutatásokban, napjainkban egyre elfogadottabb az a nézet, hogy az elmúlt évszázadok európai és magyarországi, cigány/roma gyűjtőnéven ismert közösségek sem történeti, sem néprajzi, sem szociológiai szempontból nem írhatók le homogén, differenciálatlan entitásként. A cigány/roma embereket, illetve közösségeket a történelem folyamán nem ugyanazok a kritériumok tették cigánnyá/romává, ezért őket elsődlegesen a társadalmi helyzetük alapján kell megismerni, hogy integrálódásuk lehetővé válhasson, és az iskolázásnak, a kötelező foglalkoztatásnak, a cigánytelepek felszámolásának hazai és uniós programjai valóságos társadalmi felemelkedési utakat nyithassanak.

Published: June 2022

Highlights:

Rare occurrence of a large, well-differentiated primary renal neuroendocrine tumor in a young man.
Identifying primary renal NET from the workup and histological examination of renal tumors needs to be done to understand more of this infrequent type of tumor.

Abstract:
Neuroendocrine Tumors (NETs) are a diverse range of neoplasms with various biological and histologic features and therapeutic responses. The prevalence of primary renal carcinoids is scarce worldwide. At the moment, complete surgical resection is the primary treatment against primary neuroendocrine tumors of the kidney. Nephrectomy followed by the lymph node dissection is a standard procedure for localized primary renal NETs. Since renal carcinoid tumor is extremely rare, we decided to present a unique case of a 25-years-old male with neuroendocrine renal carcinoid tumor following radical nephrectomy. The results indicated a solid, solitary tumor verified on the frozen section because a postoperative CT–scan showed a recurring mass in the renal fossa following radical nephrectomy. The case emphasized the need to investigate primary renal NET in the workup and histological examination of renal tumors and also contributed to our understanding of this infrequent clinical entity.

Abstract:
The cognitive, motor and language aspect of HIV-infected children is an important issue affecting their quality of life. The capute scale, divided into Cat and Clams scores, is commonly used to assess children's cognitive, motor, and language functions. This study assessed Cat and Clams’ scores of HIV-infected children. We performed Cat and Clams assessment on 136 children consisting of 68 HIV-infected children and 68 normal children as control aged 0-36 months. The Capute scale examined both groups at the first meeting (first month), and for the rest six months, we evaluated the progress of cognitive, motor, and language development. In the first meeting, we found that HIV-infected children had significantly low capute scores than the control group. The sixth-month Capute score in HIV-infected children was also significantly lower than the control group. HIV-infected children had lower Capute scores than normal children.
