And studied the preferred nesting sites and its spatial distribution in the capital of Belarus. Significant differences in the population density of magpies in the urban landscapes of Minsk were revealed, which correlated with the degree of their anthropogenic transformation and the characteristics of their residential development. Practical measures are proposed to regulate the number of magpies in places of their mass concentration. It is concluded that the reason for the active synanthropization and increase in the number of magpies was the growth of tree plantations in the squares and parks of Minsk. The practice of not pruning old trees also played a certain positive role. The combination of all these factors led to an increase in the number of magpies.

Published: June 2022

In the present work we carried out a comparative analysis of independent methods of verification of the number of monitor units of the radiation therapy irradiation plan. In the course of the work, verifications were carried out using theoretical calculations for irradiation fields with different geometric parameters and with the help of computer systems for radiation planning. Based on the data obtained, it is shown that it is impossible to expect an exact or almost exact coincidence of the results of these two calculations, since the theoretical verification is performed using simpler geometric models and calculation algorithms than the calculation using a computer planning system. It was also found that for the same rectangular field for different accelerators in isocentric conditions, with the same emission energy and the same SSD, the amount of ME is approximately equal and does not exceed 3%.

YST-сells role in inflammatory bowel disease is still not fully investigated: on the one hand, they are thought to be involved in dysregulation of the immune response to gastrointestinal commensal bacteria in genetically susceptible individuals and, on the other hand, YST-cells may initiate repair of damaged intestinal epithelium and exhibit immunoreg-ulatory effects. The composition of T-lymphocytes subsets (авТ-cells, YST-cells) and the expression of functional molecules (TLR4+, CD314+, CD8+, CD45RO+) on circulating YST-cells in patients with inflammatory bowel disease were characterized in this study. An increase of YST-cells numbers predominantly expressing a cytotoxic phenotype along with a depletion of YST-cells memory population in peripheral blood of patients with Crohn’s disease and ulcerative colitis has been shown, what may reflect impaired tolerance mechanisms and results from chronic stimulation to autoantigens.

Este artículo presenta los resultados de una investigación cuyo objetivo fue describir la percepción de inseguridad que manifiestan los periodistas de radio, televisión y prensa escrita destinados a la cobertura legislativa, en la ciudad de Asunción, Paraguay, en el año 2019. En cuanto a la metodología desarrollada para este estudio fue de tipo descriptiva, valiéndose del paradigma cuantitativo, con diseño transeccional y observacional. Como técnica de recolección de datos se ha utilizado la encuesta, y como instrumento el cuestionario. La población seleccionada para este estudio corresponde de 30 participantes, 17 masculinos y 13 del sexo femenino, 20 periodistas de radio, 6 de prensa escrita y 4 de televisión. Los datos producidos demuestran que la percepción de la inseguridad ha aumentado en un 87%, mientras que solo el 13% señalaron que ha disminuido, al mismo tiempo estos valores guardan una relación directa con el manejo de la información periodística de los medios, ya que los encuestados señalaron que en un 93% el periodismo infunde mucha información sobre la delincuencia y sólo el 7% responde que el periodismo no infunde mucha información sobre hechos delictivos. En este punto es de resaltar que los periodistas informan, forman y entretienen, y que su percepción de seguridad tiene influencias en cada contenido de información del ámbito de la inseguridad, así como los medios de comunicación se ubican en un espacio estratégico para la generación de contenidos y discursos sociales, y visto el contexto actual es posible considerar que inducen a asumir un discurso de miedo que no sólo es funcional a ciertos intereses empresariales, sino que impactan directa o indirectamente sobre derechos básicos de los ciudadanos y ciudadanas, repercutiendo en la vida cotidiana de la sociedad paraguaya.

Local chickens are generally kept by people in rural areas with extensive or traditional rearing systems. In general, the productivity of native chickens kept traditionally is still low. The intensive selection carried out by Balitbangtan produces superior native chickens in terms of productivity and adaptation, namely the Kampung Unggul Balitbangtan (KUB) chickens. The superiority of KUB chickens is thought to also have superior reproductive performance, one of which is the timing of puberty.  This study used each of 15 types of KUB chickens and local native chickens that were kept 2 months old. Research chickens were kept in the same cage in a different room. The feed given in the morning before the chickens were released was only in the form of rice bran. Then the chickens are released to find their own food throughout the day. The parameters measured in this study were the time of puberty or sexual maturity which was marked by the first egg production by female chickens. This study used the Independent Sample T-Test and analyzed using the SPSS application. The conclusion of this study is that the period of puberty or the first time the chickens laid eggs traditionally reared KUB chickens are faster than local native chickens. In the maintenance system, the puberty time for both KUB and local native chickens that are kept traditionally is longer than those that are kept intensively.

Authors:   Jinnah hospital, Lahore, Arif Syed Usama
Published: June 2022

Introduction: Sustained weight loss after gastric bypass is achieved by a combination of gastric restriction and a variable degree of malabsortion and has therefore a greater risk for gallstone development than purely restrictive procedures like adjustable gastric banding. Objectives: The main objective of the study is to analyse the surgical treatment of gallstones in patients undergoing gastric bypass surgery as a treatment of obesity. Material and methods: This randomized control trial was conducted in Jinnah Hospital, Lahore during 2021 to 2022. Patients who underwent bariatric surgery for obesity were included in the study. Those who had cholecystectomy before bariatric surgery, those who underwent concomitant cholecystectomy (CC) during bariatric surgery, those with concomittant gall stoness and those who did not attend their follow-up regularly were excluded from the study. Results: The data was collected from 100 patients and we reviewed records from all patients treated for acute biliary pancreatitis. The average age was 36.43±9.52 years and, the ratio of women/men was 151 (81.6%)/34 (18.4%). Mean BMI was determined as 44.16±5.09. When comorbidities were evaluated, 116 (62.7%) patients had comorbidity, while 69 (37.3%) patients did not. Conclusion: It is concluded that prophylactic and selective management can be safely performed and the only significant difference with patients not submitted to concomitant cholecystectomy is mostly observed in operative times that are higher in those who do undergo cholecystectomy.

Objectives: The main objective of the study is to find the role of aminotransferase in patients of type 2 diabetes mellitus. Methodology of the study: This cross sectional study was conducted in BVH, Bahawalpur during 2021. The data was collected from 100 patients of both genders. Patients whose fasting plasma glucose (FPG) ≥126 mg/dl on 2 occasion were included in the study. Patients with any concomitant diseases which can alter liver function and patient with hepatitis, alcoholic and taking any medicine were excluded from the study. Results: The data was collected from 100 patients with a mean age of 53.72 ± 9.82 years old and mean duration of disease of 7.41 ± 6.01 years were included in the final analysis. There were no significant difference in the levels of Fas, AST, Cl, K, Ca, BUN, creatinine and uric acid in type II diabetics compared to the non-diabetic healthy control group. Conclusion: Serum alanine aminotransferases are frequently high in patients of type 2 diabetes mellitus. However, there was no association with gender, body mass index, or duration of diabetes.

Introduction. Pathogenic Escherichia coli present a real threat to human health. One of the ways of transmission of these isolates is via environmental water sources. Therefore, evaluation of pathogenic potential of E. coli population in water is of great interest. Purpose of the study. The aim of this study was to compare E. coli isolates from wells, sewers, water pools and surface waters were compared with two control groups - “non-pathogenic” isolates from feces of healthy people and “potentially pathogenic” from feces of people with inflammatory bowel diseases (IBD). Materials and methods. PCR-assay was used to detect potential virulence genes. 19 E. coli virulence genes were analyzed: 11 toxins, 5 adhesion and invasion proteins and 2 diarrhogenic serotypes. The PCR identification of carbapenemase genes and various E. coli pathotypes was performed with the commercial “Amplisense” kits according to the manufacturer’s instruction. The assay was performed on 47 E. coli isolates from water environmental sources (WES), 44 isolates from feces of “practically healthy” people, 43 isolates from feces from IBD patients. Results. Isolates from WES were found to be similar to the group of isolates from healthy people. Only 2 types of virulence E. coli were detected in these groups - toxins CNF1 and 2 and invasin einv. IBD group of isolates demonstrated striking difference from the others. Only IBD isolates demonstrated such genes as adhesion regulator aggR, invasive antigen ipaH, hemolysin hly and antibiotic resistance gene NDM. CNF1 gene was found in IBD group significantly more often, than in two other groups. The only pathotype detected in the samples analyzed, enteroaggregative, was limited to the IBD group, too. Limitations. To compare the pathogenetic potential of E. coli from human feces and environment, 134 isolates were tested for 19 pathogenic genetic determinants, which is a representative selection. Within the analysis, we were unable to compare bacterial pathogenic potential from various environmental sources (surface waters and sewage, treatment facilities etc.) due to the uneven representation of these objects in the selection. It will be the subject of our future studies. Conclusion. Pathogenic potential of E. coli isolates from environmental water sources was close to that from healthy human feces.

The literature review examines the main previously published and current regulatory documents regulating the work of women, lists harmful and dangerous factors characteristic of the work of drivers of freight, passenger and motor-car railway rolling stock. Railway transport refers to enterprises with a continuous technological process, a shift nature of work and work at night. Driving professions related to train traffic and shunting work are characterized by a high level of nervous and emotional tension. The modernization of modern production leads to a weakening of the adverse influence of factors of the production environment (physical, chemical), the severity of labour and an increase in nervous and emotional tension, hypodynamia and hypokinesia, work regimes. The work of a woman of reproductive age in harmful working conditions will inevitably affect not only her health, but also the child born to her. To solve the issue of the possibility of attracting women to work in railway transport as a machinist and assistant machinist of electric rolling stock of high-speed and high-speed traffic, comprehensive physiological and hygienic studies of the profession of a machinist and assistant machinist in railway transport from the point of view of the physiological and psychophysiological characteristics of the female body should be performed. The review provides state social guarantees for the protection of the health of working women, especially during pregnancy, proves the need for scientific justification of hygienic requirements that ensure the safe work of women in the profession of a machinist, as well as measures and requirements for the prevention of violations in the state of reproductive health. In preparing the review, the databases Scopus, Web of Science, Medline, The Cochrane Library, EMBASE, Global Health, CyberLeninka, RSCI were used.

Introduction. There is a potential risk of harm to kid health when using toys, in particular, there is a possibility of micro-fungi entering the oral cavity of a baby when using bath toys, which may be the cause of mycotic diseases. The study was initiated by the appeal of the Russian TV First Channel to the Institute of Medical Mycology named after P.N. Kashkin, where samples of used bath toys with a black scurf inside were transferred for research and evaluation of their safety. The purpose: to evaluate the safety of the presented samples of baby bath toys after their intended use. Materials and methods. The experimental group was represented by four baby toys for the bath, which were used for their intended purpose, and were operated for several months. As a control, 4 similar toys for the bath were used. The study of the inner surface of the toys of the experimental group was carried out using a Leica DM 4020 light microscope,and sowing scrapings on Sabouraud’s solid nutrient medium. Isolates were determined by MALDI-TOF mass spectrometry. The inner surface of the toys was also studied by scanning electron microscopy. The fungus resistance of the samples was assessed according to GOST 9.049-91. Results. The study of the inner surface of prototype toys for the bath established the well-developed and “young” biofilms in the black areas of the inner surface. Biconvex spores (2×3 μm) of fungal origin were identified. Inoculation of swabs from the inner surface revealed a massive growth of opportunistic fungi: yeast fungi Candida guilliermondii (Castell.) Langeron & Guerra and Rhodotorula spp.. Studies on the fungus resistance of control samples of toys show that the material is not a nutrient medium for microfungi (neutral or fungistatic). Limitations: a relatively small sample of samples, the use of expensive high-tech equipment, the difficulty of reproducibility of the result. Conclusion. Colonization of the interior surface of toy specimens used in bathing kids with microscopic fungi and bacteria is indicative of a potential risk of harm to infants due to product design, period of use, and possibly materials used. In this regard, it is necessary to review the hygienic safety requirements for the design of bath toys and make appropriate additions to the Technical Regulations of the Customs Union “On the safety of toys” (TR CU 008/2011). Safety can be ensured by the requirement of tightness of the body of toys, as well as a significant reduction in the service life of such products.
