Assessment and condition of a small river in urbanized areas (with the example of the river Kurdyum of the municipal formation “Saratov city”)
Authors: Belikov А. S. , Boldyrev V. A. , Sedova O. V.
Published: October 2024

The results of the study of the ecological status of the Kurdyum river within the municipal formation “Saratov city” are presented. The hydrochemical regime, hydrophilic flora and vegetation of the watercourse were studied in the 2022–2023 field seasons. The ecological status of the river by structural parameters of macrophytes was assessed. The species composition of aquatic plants in the river Kurdyum was represented by 41 macrophyte species belonging to 32 genera, 23 families and three divisions (Charophyta, Polypodiophyta, and Magnoliophyta). The families Potamogetonaceae, Asteraceae, Poaceae, Typhaceae and Ranunculaceae predominated by the number of species. The genus Potamogeton contained the greatest number of species (four) while other genera were represented by one – two species. Hydrophytes were a numerous ecological group, accounting for 51% of the total number of species. New locations of species rare for the Saratov region (Myriophyllum verticillatum and Zannichellia palustris) were revealed. The vegetation cover of the Kurdyum river is characterized by the greatest phytocenotic diversity of true aquatic vegetation. The impoverishment of the phytocenotic composition of helophytic and hygrophytic vegetation is explained by the lack of favorable conditions for the development of their phytocenoses (the watercourse has abrasion banks along a significant length) or trampling and eating by grazing animals. The studied river is characterized by species diversity in comparison with previously studied urban watercourses. Index comparison has revealed an inverse relationship between species diversity and the level of anthropogenic load. Cluster analysis has revealed that the structure of flora and vegetation from the source to the mouth of the river is not homogeneous and is formed under the influence of a combination of hydrological, chemical and anthropogenic factors. The results of our chemical analysis of the water showed that the maximum permissible concentrations of Fe, Zn, Cu, surfactants, NO2 and NH3 were exceeded throughout the river. However, the environmental indicators assessed based on the structural parameters of macrophytes allow us to consider the ecological status of the watercourse satisfactory. Thus, the Kurdyum river is moderately polluted with a high trophic status.
Contact zone of European (Meles meles Linnaeus, 1758) and Asian (M. leucurus Hodgson, 1847) badgers (Mustelidae, Mammalia) in the rightand left-bank districts of the Saratov region
Authors: Oparin M. L. , Kartavov N. A. , Oparina O. S. , Sukhov S. V. , Titov S. V.
Published: October 2024

DNA studies of badgers (Meles sp.) from the right-bank and left-bank areas of the Volga river in the Saratov region are described. Asian badgers (Meles leucurus Hodgson, 1847) inhabit the Left Volga Bank of the Saratov region, while European badgers (M. meles Linnaeus, 1758) inhabit the Right Volga Bank districts of the region, but Asian badgers were found in Khvalynsky district of the Saratov region, besides the European badger. Despite a sufficient number of publications devoted to the Asiatic badger distribution in the Vyatka–Kama region and the Volga region, and studies devoted to the development of systematics of the genus Meles in Russia, the question of the boundaries of the ranges of European and Asiatic badgers and the zones of their sympatry (parapatry) in the Volga–Kama region has not been fully investigated to date. Our work is devoted to the study of this question. As a result of analyzing the biological material collected by us, it was found that all five studied individuals of badgers from the Saratov Volga region phenotypically looked like Asian badgers, but our DNA analysis showed that only two of them were M. leucurus, whilst three ones were heterozygous individuals carrying genes from both species and were identified as hybrids. The remaining 29 individuals were captured in the right-bank areas of the region. Badgers were sampled from individuals from the northern to southern borders of the region in areas located along the Volga river on the Volga upland and in the Oka–Don plain. Of these, one individual from Khvalynsky district turned out to be an Asian badger, one individual from Krasnoarmeysky district was a hybrid of the two named species, and three individuals, one from Tatishchevsky, the second from Volsky and the third from Khvalynsky districts showed introgression of Asian badger genes into the genotype of the European badger. Thus, we have managed to find out that at this stage of development of the phase of the climatic cycle in the Lower Volga region, characterized by warming winters, the Volga river, with its two reservoirs within the Saratov region, is not an absolute zoogeographical boundary, and badgers, whose species are characterized by winter sleep, can in certain conditions overcome, most likely on ice, both the river itself and the lake parts of the Volgograd and Saratov reservoirs. According to the revealed introgression in some individuals from different areas on the Volga upland of the right bank of the Saratov region, it can be assumed that such traveling across the Volga river took place earlier, possibly before its flow was regulated by dams.
Common hamster (Cricetus cricetus, Cricetidae, Rodentia) in the Simferopol city: Population dynamics and survival outlook
Authors: Zaytseva E. A. , Tsellarius A. Yu. , Bogomolov P. L. , Kuptsov A. V. , Surov A. V.
Published: October 2024

In the Simferopol city, the numbers of Common hamsters began to grow since the early 1970s and reached a peak in the mid-1990s. The abundance was kept at a high level until 2014–2015 and then began to decline. In multi-storey residential development areas, steady settlements of hamsters have now virtually disappeared, and even in large green areas (the City Park and Botanical Garden), the numbers dropped almost tenfold. One of the possible causes for this decline was cutting down shrubs and hedges, which began since 2016–2017. However, the population has also severe declined in areas with no such activities. Thus, the fate of the Simferopol hamster population is worrisome. Obviously, we are dealing with a multi-factor process which requires special studying, without which no estimating of population viability or developing of conservation measures are possible.

Published: October 2024

This study assessed the mechanical properties of hybrid composite vulcanizates made from natural rubber with ceramics industrial waste and carbon black as filler. Ceramic waste was characterized using Xray Diffraction (XRD) and Xray Fluorescence (XRF). Natural rubber (NR) was filled with ceramic powder and carbon black at varying ratios of filler loading as follow; 00, 60/00, 50/10, 40/20, 30/30, 20/40, 10/50, 0/60. The mechanical properties of the hybrid composites evaluated include; tensile strength, young modulus, Flexural Strength, Flexural modulus, Abrasion Resistance and hardness. The result obtained shows the presence of SiO2, Al2O3, Fe2O3, TiO2, CaO, MgO, Na2O, K2O in the ceramic composition and SiO2 appears to be the largest compound in the ceramic. The ceramic/CB ratio of 40/20 shows the highest tensile strength (40.00 MPa), while the modulus was highest with ratio of 60/0. The highest flexural strength (27.00 MPa) was at ceramic/CB ratio 0/60 while the lowest (19.67 MPa) was at ratio of 60/0. The flexural modulus of NR composite began to increases and peaked as the CB increases with the ceramic (40/20 pphr) filler loading at 436.33 MPa. The hardness of the hybrid composite increased as the CB concentration increased with maximum hardness obtained with ceramic/CB ratio 20/40 (47.00 shore A). At ratio of 30/30 the wearing rate was lowest (higher abrasion resistance) at 97.89, Ceramic waste can improve the mechanical properties of the natural rubber vulcanizates by increasing its elasticity, and abrasion resistance if used alone as a filler.

Intertextualitás és feminista újraírás: frankensteini visszhangok Alasdair Gray Szegény párák című művében
Authors: Miklós Nóra
Published: October 2024

Tanulmányom központi témája az a komplex intertextuális kapcsolathálózat, amely által Alasdair Gray Szegény párák című regénye dialógusba lép Mary Shelley Frankenstein, avagy a modern Prométheusz című alkotásával. Feltevésem, hogy a Szegény párák bizonyos értelemben ott folytatódik, ahol a Frankenstein, avagy a modern Prométheusz abbamarad, és hogy az előbbi valójában intertextuális válasz az utóbbira. A dolgozatban különböző intertextusok felől tárom fel a Gray-regény frankensteini visszhangjait, amelyhez az irodalom emlékezetére hangsúlyt fektető Renate Lachmann elméletét veszem alapul. Elemzésem arra a feminista olvasatra éleződik ki, amely a két történet kapcsolódásában megmutatkozik. Úgy vélem, hogy miközben válaszokat keres egy sajátosan női szörnyűség mibenlétére, a Szegény párák kitölti Mary Shelley regényének feminista csendjeit.

Resumo Fundamento A Doença de Chagas (DC) representa um grave problema de saúde pública na América Latina. O Benznidazol (BNZ) é utilizado para o tratamento DC e, apesar do seu amplo uso, poucas informações estão disponíveis sobre sua toxicidade e mecanismos das Reações Adversas ao Medicamento (RAM). Objetivos Identificar e classificar as reações adversas clínicas e laboratoriais ocasionadas pelo uso do BNZ quanto à sua causalidade e gravidade. Métodos Estudo de coorte prospectivo realizado no período de janeiro de 2018 a dezembro de 2021. O acompanhamento do tratamento incluiu consultas e análises laboratoriais antes, 30 e 60 dias após o início do tratamento. As RAM foram classificadas quanto à causalidade e gravidade. Na análise estatística o nível de significância adotado foi p<0,05. Resultados Participaram do estudo 40 pacientes com DC crônica, observou-se alta prevalência de RAM com um total de 161 em 30 (90%) pacientes. Destas, 104 (64,6%) foram classificadas como possíveis e 57 (35,4%) como prováveis. As reações foram classificadas em moderadas e leves. Dos 40 pacientes, nove (22,5%) suspenderam o tratamento. As RAM associadas à interrupção e intervenções foram as que afetaram o sistema dermatológico, sistema nervoso central e periférico ou que culminaram em ageusia. Após 30 dias de tratamento, alterações hematológicas e bioquímicas leves foram observadas como linfopenia. Conclusão Apesar do elevado percentual de RAM, muitos pacientes foram capazes de completar o tratamento, o que se atribui ao êxito da estratégia de acompanhamento com intervenções de tratamento sintomático juntamente ao aconselhamento, levando à compreensão da sintomatologia e manutenção do tratamento.

Resumo Fundamento: O fondaparinux é um anticoagulante eficaz e seguro usado no tratamento de síndromes coronarianas agudas (SCAs). No entanto, devido à baixa representatividade de indivíduos obesos em ensaios clínicos, os efeitos de se aplicar os resultados desse medicamento nesta população continuam incertos. Objetivos: Comparar o fondaparinux à enoxaparina no tratamento de obesos com SCA. Métodos: Este é um estudo do tipo coorte retrospectivo, incluindo indivíduos obesos (IMC ≥ 30 Kg/m2) internados com Infarto do Miocárdio sem Elevação do Segmento ST (IAMSSST) ou Angina Instável (AI) e tratados com fondaparinux ou enoxaparina entre 2010 e 2020. Os grupos que receberam fondaparinux e enoxaparina foram comparados quanto suas características clínicas e laboratoriais usando o teste do qui-quadrado e o teste de Mann-Whitney, conforme apropriado. A incidência dos desfechos primários (morte, reinfarto, acidente vascular cerebral, sangramento maior) foi comparada entre os grupos. Um p<0,05 foi considerado estatisticamente significativo em todas as análises. Resultados: Um total de 367 pacientes obesos com IAMSSST ou AI foi incluído, dos quais 258 usaram fondaparinux e 109 usaram enoxaparina. A idade média foi 64 ± 12 anos, 52,9% eram do sexo masculino. A prevalência e diabetes, hipertensão, dislipidemia, doença arterial coronariana prévia, acidente vascular cerebral prévio, e implementação de estratégia invasiva foi similar entre os grupos. A incidência do desfecho primário foi 4,7% no grupo fondaparinux e 5,5% no grupo enoxaparina (p = 0,729). Não houve diferença entre os grupos quando os componentes do desfecho primário foram analisados separadamente. Conclusão: Em uma amostra de pacientes obesos com IAMSSST ou AI, não houve diferença na ocorrência do desfecho composto (morte, acidente vascular cerebral, reinfarto, sangramento maior) entre os pacientes que utilizaram fondaparinux ou enoxaparina.

Published: October 2024

Nowadays, metrology has employed advanced techniques such as artificial intelligence, the internet of things and data analysis, all with the aim of accurately and precisely measuring different physical magnitudes. All this is known today as metrology 4.0, which has as its main objective to ensure the reliability and accuracy of measurements in fields such as industry. In this context, a web application is proposed for a company dedicated to the calibration of instruments, in which regression algorithms are applied for prediction in their calibration instruments. This will not only provide better quality and more reliable results to customers, but will also optimize the company's processes and improve the efficiency of decision making related to instrument calibration. It is expected that, through the use of regression algorithms, the company will predict when the standard instrument will give bad readings. This will make it possible to send the instrument for calibration in advance, avoiding errors and guaranteeing measurement accuracy. Although concrete results are not yet available, a significant improvement in the accuracy and reliability of predictions is anticipated, as well as in the company's operational efficiency.

Factors Mediating Lung Cancer in Never Smokers Identified from Epidemiologic Analysis
Authors: Guo Kevin , Cho William C , Dako Farouk
Published: October 2024

Lung Cancer in Never-Smokers (LCINS) is one of the leading causes of cancer patient deaths in the United States. Unlike lung cancer onset by cigarette smoking, LCINS is not as readily understood and research on the subject has been conflicting. Thus, early diagnosis and prevention are key in reducing mortality among LCINS patients. In this study, the Prostate, Lung, Colorectal, and Ovarian (PLCO) dataset contains more than 155,000 participants and over 36,000 never-smokers. Data from more than 5,000 patients with LCINS were analyzed using R and Excel software to determine risk factors of LCINS. The factors analyzed for predictive power in LCINS incidence were age, height, weight, body mass index, race, income, family history, and secondary smoke exposure. Multiple statistical methods, including t-tests, ANOVA tests, and logistic regression, were implemented to assess each factor. Through comparison and corroboration of results from these statistical methods, age and race were identified as the key factors that had statistically significant evidence as potential influences in LCINS incidence. This was indicated by strong positive correlation between age/race and the predicted probability of LCINS development with a statistically significant p value. Other physical characteristics did not appear to have a significant impact on the likelihood of developing LCINS. In addition, the statistical method that provided the most information regarding a factor’s power was logistical regression due to the binomial outcome of whether or not a patient has LCINS. It enables a deeper elucidation of how individual factors influence the probability of LCINS development. These results provide valuable insights into demographic risk factors for LCINS and lay the groundwork for future investigations, potentially including the application of advanced analytical techniques such as deep learning algorithms to explore additional predictive factors for LCINS and other lung cancer subtypes.

Co-occurrence of two types of cancers, especially lung and colorectal cancers is rare. This study investigated patients at Bach Mai Hospital who were diagnosed with two or three cancers. Only a few patients concurrently had two cancers. Positron emission tomography (PET)/computed tomography (CT) was used for the staging of cancer, especially synchronous malignancies. In this report, we have presented the case of a patient diagnosed with rectal and lung cancer based on CT, magnetic resonance imaging, and PET/CT scans as well as immunohistochemistry. Managing terminal synchronous cancers is challenging. The efficacy of the preferred anticancer therapy must be considered to ensure patients’ quality of life. Although the combination of tyrosine kinase inhibitor-targeted therapy and chemotherapy is promising, its toxicity remains unknown. Our patient received two cycles of mFOLFOX6, afatinib, and bisphosphonate. However, the treatment was discontinued due to grade 3 stomatitis and grade 2 anemia. Despite recovery and partial response in terms of symptom and tumor marker reduction, the patient refused further treatment and chose palliative care.

Pancreatic cancer is increasingly prevalent and characterized by a high mortality rate. Due to the limitations of current diagnostic methods, early-stage detection remains elusive, contributing to persistently low survival rates among affected individuals. Nanomaterials have garnered significant attention in cancer research for their potential diagnostic applications. Among these, MXenes – a novel family of two-dimensional nanomaterials composed of transition metal carbides, nitrides, and carbonitrides – are of particular interest due to their unique properties. These include high electrical conductivity, hydrophilicity, thermal stability, large interlayer spacing, tunable structure, and high surface area. These characteristics make MXenes highly effective for detecting trace amounts of various analytes. In addition, their tunable structure enables precise manipulation of their properties, allowing for optimized sensing responses. Montmorillonite nanoclay (MMT), a member of the smectite group of natural clay minerals, is known for its ability to promote bone development and influence cell behavior. When combined with MXenes, MMT forms promising nanocomposites for early pancreatic cancer detection through sensing applications. The Ti3C2 MXene-MMT nanocomposites exhibit potential as scaffold sensors capable of distinguishing cancerous from non-cancerous samples by observing the distinctive patterns in resistance changes. In addition, MXenes possess excellent selectivity, allowing for the reliable identification of targeted analytes from a complex mixture of chemical and biological analytes. Due to the advanced sensing capabilities of MXene-MMT composite scaffold sensors, they hold great promise for early cancer diagnosis and tissue regeneration, providing a novel therapeutic approach to improving patient outcomes.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of human epidermal growth factor receptor 2, estrogen receptor, and progesterone receptor expression. While traditional TNBC treatment primarily relies on systemic chemotherapy, epigenetic modification has an important role in immune evasion and tumor progression. Recent classifications of TNBC into “hot” and “cold” tumors, based on immune activity and mutation burden, have revealed that poor response to immune checkpoint inhibitors (ICIs) in these tumors is due to low tumor-infiltrating lymphocytes and the presence of immunosuppressive cells. Emerging treatments such as ICIs and poly(ADP-ribose) polymerase inhibitors offer promising alternatives. The tumor microenvironment (TME) shapes immune responses in TNBC, and a limited subset of patients has shown encouraging responses to ICIs in treating TNBC at both early and advanced stages. However, combination therapies face challenges, including medication interactions and side effects. Epigenetic modulators, such as histone deacetylase and DNA methyltransferase inhibitors, also show promise in reversing epigenetic changes by enhancing anti-tumor immunity in TNBC. The frequent expression of indoleamine 2,3-dioxygenase 1 (IDO1) in TNBC, which catalyzes the conversion of tryptophan to kynurenine, contributes to immune suppression in TNBC patients. High IDO1 levels impair the tumoricidal activity of natural killer cells and correlate with poor responses to anti-PD-L1 therapy, which can be improved using IDO1 inhibitors. Targeting myeloid-derived suppressor cells, regulatory T-cells, and tumor-associated macrophage, along with utilizing epigenetic mechanisms, show promise in modulating the immunosuppressive TME in TNBC. Combining these approaches with standard therapies, along with biomarker-guided patient selection, can enhance treatment efficacy. Clinical trials and preclinical models are essential for optimizing these strategies. This study emphasizes the importance of understanding the mechanisms of modulation, tumor-immune interactions, and the potential of epigenetic therapies in improving treatment outcomes in TNBC.
