The purpose of this research was to study the effect of the vitamin‐mineral complex E‐selenium and the probiotic preparation Bacell when added to industrial feed on the fish‐breeding‐biological and physiological‐ biochemical parameters of juvenile sterlet‐beluga hybrids when reared in cages.The duration of the experiment was 45 days. In experimental option 1, the fish were fed with basic compound feed with the addition of E‐selenium (300 μg selenium/kg of feed), in experimental option 2, the fish were fed with basic compound feed with the addition of E‐selenium (300 μg selenium/kg of feed) and the Bacell preparation (0.2 % by weight of dry food). The control variant was fed with basic feed.The absolute increase in the experimental variants was 13.0–25.0 % higher than in the control. Hematological parameters varied – in some cases with a high degree of significance. In particular, hemoglobin increased by 5.6–13 %, blood serum protein by 0.42–12.6 %, cholesterol by 9.8–16.3 % in the experimental variants and by 70.5 % in the control, due to the presence of a high degree of stress in control fish. At the same time, in fish experiments the effects of stress factors were suppressed by antioxidants. Preventive doses of microelements, vitamins and probiotics reduce and stabilise peroxide processes and contribute to the maintenance of good physiological condition of fish kept in artificial conditions.

Authors: Radzhabova R. T. , Akhmedova L. Sh. 
Published: October 2024

Aim. The research and mapping of natural object dynamics using aerial and satellite imagery is one of the long‐established and actively developing fields of remote sensing and geographic research. The current phase is characterised by the wide availability of remote sensing data processing software, which offers almost unlimited possibilities for transforming and integrating datasets from different periods.Material and Methods. For the effective use of archival maps in studying territorial dynamics, two interconnected factors are critical: the date of the map’s creation and the positional accuracy of the mapped objects. The materials used in this study were TM/Landsat satellite images from the periods 2002–2017 and 2006–2014.Results. Reservoirs with a surface area of up to 60–70 km² and a volume of up to 250 million m³ increase absolute air humidity by 10–15 %. In areas with a hot climate, the impact of a reservoir on air humidity is even more pronounced.Conclusions. The anticipated significant changes in the microclimate are expected to affect the structure of agricultural production in the Irganay valley and in the villages of Maidanskoye, Untsukul, and Gimry, particularly through changes in precipitation distribution during the growing season.

The new coronavirus infection caused by SARS‐CoV‐2 is a dangerous respiratory disease. The aim of the investigation was to study the pathomorphological changes in lungs of Syrian hamsters infected with SARS‐CoV‐2 as is necessary for adequate therapy and prevention of the disease.Syrian hamsters of the SPF category were infected intranasally with a dose of 5×105TCID50 SARS‐CoV‐2/human/RUS/Nsk‐FRCFTM‐1/2020). Animals were euthanised on days 3, 6, 10, 14 and 21 after infection and the lungs were collected. To determine virus replication real‐time RT‐PCR was used. The lungs was used for histological examination. Statistics was performed using Statistics for Windows 10 software.Specific pathological lesions characterising the inflammatory process were detected in all groups of animals. The severity of pathological changes and the volume of lung tissue lesions varied depending on the stage of the disease. The most severe lesions were observed on days 6–10. By day 21, the process of organ structure restoration was noticed.The study showed that pathological changes in the Syrian hamster’s lungs caused by experimental infection with the SARS‐CoV‐2 were multifaceted and complex. In mild cases, congestion and infiltration are observed, and in severe cases, atelectasis and pulmonary edema were life‐threatening. The most severe lesions in lungs were noted on days 6–10. By day 21, the process of restoration was observed.

Published: October 2024

Aim. For the first time, flow cytometry has been used to study the structure and functional characteristics of bacterio‐, pico‐ and nano‐ phytoplankton in the Middle Caspian during the bloom period in early September 2022.Water samples were taken at different horizons (from the surface to the bottom layer) at a series of stations along the western coast of the Caspian Sea on the border between its northern and central parts to quantitatively assess heterotrophic bacterioplankton, picophyto‐ and nanophy‐ toplankton. Sampling was undertaken in early September 2022 under summer hydrological conditions with water surface temperatures ranging from 24.7°C to 26.7°C. Sample analysis was performed using flow cytometry.Extremely high concentrations of picophytoplankton (up to 1.8×105 cells/mL), probably of Synechococcus picocyanobacteria, were detected off the northwestern coast of the Middle Caspian. Very high values of nanophytoplankton abundance (up to 1.6×105 cells/mL), dominated by small flagellates, were also found. A clear spatial uncoupling of pico‐ and nanophytoplankton was revealed. Maximum levels of nanophytoplankton were confined to the area of intensive phytoplankton blooming with high concentrations of chlorophyll a, while picophytoplankton reached peak abundance further south, outside this area. The influence of the thermocline on the vertical structure of microbial communities was detected. The concentrations of picophytoplankton and the proportion of physiologically active HNA‐bacteria decreased sharply under the thermocline.The results obtained indicate the leading role of the smallest phototrophs in the Caspian pelagial and emphasise the need for further comprehensive studies of Caspian microbial communities using modern methods.

Authors: Çiçek Ramazan , Dinç Ayten 
Published: October 2024

Background: Hematopoietic stem cell transplantation is a life-saving treatment method for numerous diseases. This study aims to determine the knowledge and attitudes of Faculty of Health Sciences students in a university towards hematopoietic stem cell donation and descriptive cross-sectional design.
Materials and Methods: The study participants consisted of students studying at the Faculty of Health Sciences of a university in western Turkey. A total of 345 students were available to complete a survey. The data were collected online through the Google Form. Data were analyzed using the SPSS 25 program (IBM Corp.; Armonk, NY, USA). Moreover, the Chi-square test, independent samples t-test, and one-way ANOVA were used in this study.
Results: 25.2% were registered at "The Turkish Stem Cell Coordination Center", and 89.1% of the unregistered ones wanted to be a stem cell donor. The university students had a moderate level of knowledge about stem cell donation. While the participants were more knowledgeable about stem cell collection with the peripheral method, they had poor knowledge of stem cell collection methods from the bone marrow and stem cell donation processes. There was a significant correlation between the students' level of knowledge about hematopoietic stem cell donation and their university year, occupation, age, graduate school, and parents' educational level (p<0.05).
Conclusion: In this study, it was found that the university students had insufficient knowledge on hematopoietic stem cell donation and their intention to donate stem cells was high. Holding training sessions, seminars, and conferences for university students as future health professionals to raise their awareness of stem cell donation is recommended. The fact that new-generation health professionals are sensitive and educated about stem cell donation can contribute to increasing stem cell donations in society.

Authors: Bramante Clarice Nunes , Rizzato Julia Soto , Nakamura Isabella Bagni , Galvão Taís Freire , Silva Marcus Tolentino 
Published: October 2024

Objective
To assess the absence of diabetic foot examination in Brazil and how ethnicity affected this outcome.

Design
This is an analysis of a nationwide survey held in Brazil in 2019. Participants with diabetes and that were 15 years of age or older were eligible for inclusion in the analysis. Adjusted Poisson regression with robust variance was used to calculate prevalence ratios (PRs) and 95% confidence intervals (95% CIs) of never having had the foot examined, with separate models according to ethnicity. Stata 14.2 was used for all calculations.

Results
We included 6216 individuals with diabetes; 52.1% (95%CI: 50.0%-54.2%) reported never having had their feet examined by a health care professional and 61% self-declared as Black (Black and Brown [Brazilian mixed race]). A higher frequency of negligence was observed among Black individuals (55.3%; 52.5%-58.1%) than among White individuals (48.2%; 45.0%-51.5%). Negligence was higher between 15- to 39-year-old participants (PR = 1.34, 1.14-1.57), lower educational level (PR = 1.37, 1.13-1.65), higher alcohol consumption (PR = 1.18, 1.06-1.31), fair health status (PR = 1.11, 1.01-1.21), and diabetes diagnosis of up to 10 years (PR = 1.42, 1.28-1.57). Among Blacks, tobacco use and other factors increased the frequency of the outcome, whereas participation in the Brazilian Unified Health System primary care program was a protection factor (P&lt;.05).

Conclusion
Black Brazilians with diabetes had higher negligence of foot examination by health care professionals. Strengthening primary care would help mitigate systemic racism in Brazil.
