Abstract

Uterine leiomyomas (fibroids) are the most common non-cancerous tumor affecting women. Psychosocial stress is associated with fibroid risk and severity. The relationship between psychosocial stress and fibroid pathogenesis may involve alterations in microRNAs (miRNAs) although this has yet to be examined. We investigated associations between two psychosocial stress measures, a composite measure of recent stressful life events and perceived social status, with expression levels of 401 miRNAs in myometrium (n = 20) and fibroids (n = 44; 20 matched between tissues) from pre-menopausal women who underwent surgery for fibroid treatment. We used linear regressions to identify psychosocial stressors associated with miRNAs, adjusting for covariates (age, body mass index, and race/ethnicity). Psychosocial stressors were modeled as ordinal variables and results were considered statistically significant if the overall variable significant was below false discovery threshold (FDR < 0.10) and showed a monotonic dose-response (nominal p-trend < 0.05). In the myometrium, 16 miRNAs were significantly associated with total stressful events and two miRNAs were associated with perceived social status. No fibroid miRNAs were associated with either stress measure. Pathway analyses revealed miRNA-mRNA targets were significantly enriched (FDR < 0.05) in pathways relevant to cancer/tumor development. Of the 74 differentially expressed miRNAs between myometrium and fibroids (p < 0.05), miR-27a-5p was also associated with stress exposure. Our pilot analysis suggests that psychosocial stress is associated with changes in myometrium miRNAs, and thus, plays a role in the pathogenesis of fibroids from healthy myometrium.
First report of free-living amoebae in sewage treatment plants in Porto Alegre, southern Brazil

Published: September 2023

Abstract

Free-living amoebae (FLA) are amphizoic protozoans with a cosmopolitan distribution. Some strains of species are associated with infections in humans. They feed on microorganisms by phagocytosis; however, some of these can become endocytobionts by resisting this process and taking shelter inside the amoeba. The whole world is experiencing increasing shortage of water, and sewage is being reused, so the study of this environment is important in public health context. The objective of this work was to identify FLA present in sewage treatment plants in Porto Alegre, Brazil. About 1 L samples were collected from eight stations (raw and treated sewage) in January, February, July, and August 2022. The samples were sown in monoxenic culture, and the isolated amoebae were subjected to morphological and molecular identification. Polymerase chain reaction results indicated the presence of the genus Acanthamoeba in 100% of the samples. Gene sequencing showed the presence of Acanthamoeba lenticulata and Acanthamoeba polyphaga - T5 and T4 genotypes - respectively, which are related to pathogenicity. The environment where the sewage is released can be used in recreational activities, exposing individuals to potential interactions with these amoebae and their potential endocytobionts, which may pose risks to public health.

Authors: YADAV RAHUL , RAO HARSHITA , GOEL GAURAB 
Published: September 2023

Objective: It is established that the standard treatment foracute cholecystitis is laparoscopic cholecystectomy. However, the question of the timing of surgery remains controversial. To compare early laparoscopic cholecystectomies (within 72 h of symptom onset) and delayed laparoscopic cholecystectomies (beyond 72 h) for acute cholecystitis in terms of intra-operative difficulties and post-operative complications.
Methods: The patients operated on for acute cholecystitis, between December 2018 and December 2021, were included in a prospective study. They were divided into two groups based on whether surgery was performed before (group 1) or after (group 2) 72 h after the onset of symptoms. We conducted a comparison between the two groups.
Results: The two groups were comparable in terms of demographics, clinical presentation, and radiological findings. The duration of surgery was significantly longer for group 2 (53.6 min versus 30.7 min, p<0.001). There was more conversion in group 2 than in group 1, without a significant difference (6% versus 0%, p = 0.17). There were no postoperative deaths during the study period. Specific post-operative complications were comparable between the two groups. The post-operative hospital stay was significantly longer in group 2 (9.3 d versus 5.4 d)
Conclusion: In the case of acute cholecystitis, early surgery can reduce the cost of care, the duration of surgery and the hospital stay while the conversion rate and postoperative morbidity are comparable to the delayed treatment.

Published: September 2023

Objective: Anemia is a serious global public health problem that particularly affects young children. As many as 67.1% children aged 6-59 mo surveyed suffered from anemia in 2019 and 65.5% in Karnataka, according to NFHS-5. Nutritional anemia is most common but preventable cause for anemia in children in developing countries. This is due to improper feeding habits, especially during the initiation of complementary foods. Hence the present study is to know the pattern of anemia in infants of age group between 6 mo to 12 mo and to assess the nutritional and other associated risk factors contributing to Anemia.
Methods: This study was carried out in 193 children aged 6 mo to 12 mo admitted in our hospital. Detailed clinical evaluation and relevant laboratory investigations were done as per proforma.
Results: In our study majority were of age group 6 to 9 mo (52.8%). 40.4% of mothers of our study infants were anemic during pregnancy and 9.3% were blood transfused. Majority (53.4%) were exclusively breastfed. 45.6% were started on complementary feeding at 4 to 6 mo age.17.6% were moderately wasted and 9.3% of infants were severely wasted. There was a significant association between severity of anemia and mother’s anemia, inclusion of cow’s milk in diet, adequacy of complementary feeding, and inclusion of formula feeds (p<0.05).
Conclusion: Nutritional anemia is most common cause of anemia in childhood, especially in developing countries like India. Parents and caregiver need awareness regarding the effect, causes of anemia and how to prevent it.

В ходе оценки состояния сообществ гидробионтов реки Зеи на участке строительства Амурского газохимического комплекса в 2018 г. выявлено 37 таксонов планктонных водорослей рангом ниже рода, 32 вида зоопланктона и 37 видов бентосных организмов. В мае фитопланктон представлен большей частью диатомовыми водорослями, в июле он был более разнообразен, существенную роль играли зеленые, золотистые водоросли и цианобактерии. Зоопланктон в мае включал в основном коловраток, в июле на ряде станций по биомассе доминировали ракообразные. Зообентос в мае представлен преимущественно олигохетами и двустворчатыми моллюсками, тогда как в июле доминировали насекомые. Показатели численности и биомассы фитопланктона, зоопланктона и бентоса невысоки. Индексы Гуднайта и Уитлея, Пареле, Вудивиса, Майера свидетельствуют об относительно благополучных экологических условиях на изученных участках реки. По показателям фито- и зоопланктона, зообентоса воды реки отнесены к олигосапробным.
Environmental engineering survey performed at the construction site of the Amur Gas Chemical Complex in 2018 in order to assess the state of aquatic communities of the Zeya River revealed 37 taxa of planktonic algae (below genus rank), 32 species of zooplankton, and 37 species of benthic organisms. In May, phytoplankton was mainly represented by diatoms; in July, it was more diverse, when green algae, golden algae and cyanobacteria all played a significant role. In May, zooplankton included mainly rotifers; in July, crustaceans dominated by biomass at most stations. Zoobenthos was represented in May mainly by oligochaetes and bivalves, while insects dominated in July. The abundance and biomass of phytoplankton, zooplankton, and benthos were low. The Goodnight–Whitley, Parele, Woodiwiss, and Mayer indices testified to relatively favorable environmental conditions in the studied sections of the Zeya River. According to the indicators of phyto- and zooplankton, and zoobenthos, the waters of the river are classified as oligosaprobic.

Published: September 2023

Изучено влияние ртути, поступавшей с кормом в течение трех месяцев, на некоторые биохимические показатели сыворотки крови серебряного карася Carassius auratus (L., 1758): концентрацию общего белка, общего холестерина и липопротеинов высокой плотности. Содержание ртути в мышцах рыб группы, потреблявшей корм с повышенным содержанием ртути («ВР»), возрастало в 5.8, 10.4 и 11.7 раза, с пониженным содержанием («НР») – в 1.4, 3.2 и 3.2 раза через 1, 2 и 3 месяца соответственно (p < 0.05). Накопление ртути приводило к возрастанию всех изученных показателей; максимально увеличивался уровень общего холестерина у рыб опытной группы к концу эксперимента (в 3.1 раза). При этом показана достоверная положительная связь биохимических показателей крови с содержанием ртути в мышцах рыб. Полученные результаты свидетельствуют о возникновении изменений в липидном и белковом метаболизме рыб под воздействием ртути, степень выраженности которых зависит от количества ртути в корме и длительности эксперимента.
The effect of mercury, supplied with food for three months, was studied on some biochemical parameters (concentration of total protein, total cholesterol, and high-density lipoproteins) of the blood serum of goldfish Carassius auratus (L., 1758). The content of mercury in the muscles of the fish that consumed the food with a high content of mercury (“HM”) increased by 5.8, 10.4, and 11.7 times, with a low content (“LM”), by 1.4, 3.2, and 3.2 times after 1, 2, and 3 months, respectively (p < 0.05). Accumulation of mercury resulted in increasing of all the studied parameters; the total cholesterol concentration increased to the maximum in the fish of the experimental group by the end of the experiment (by 3.1 times). At the same time, there was a significant positive relationship between the biochemical parameters of blood and the mercury content in the fish muscles. The obtained results indicated significant changes in the lipid and protein metabolism of fish under the influence of mercury, their intensity depended on the amount of mercury in the feed and the exposure time.

Описаны первые находки многоярусных пестичных морфоструктур трех типов аномалий (пролификация, «ветвистость» и фасциация) Typha laxmannii в прибрежьях о-ва Донского в дельте р. Дон. Высказано предположение, что причинами возникновения подобных структур служат возрастающая техногенная нагрузка на регион, а также трансформация ландшафта в историко-геологическом прошлом, которая привела к изоляции архаичных и мигрирующих видов рода Typha в рукавах дельты.
The article describes first findings of three multi-tiered anomalous pistillate morpho-structures (proliferation, “branching”, and fasciation) of Typha laxmannii inhabiting the coasts of the Donskoy Island, the Don River delta. It is suggested that these malformations are associated with an increasing technogenic load on the region as well as the transformation of the landscape in the historical and geological past, which led to the isolation of archaic and migratory Typha species in the delta branches.

Authors: Ермолаева Н.И. 
Published: September 2023

Проведен расчет оптимумов и пределов экологической толерантности различных видов зоопланктона по отношению к солености и к уровню рН в сложных геохимических условиях юга Западной Сибири. Показано, что в разнообразных климатических условиях у зоопланктонных организмов формируются различные пределы галотолерантности и приспособленности к диапазону значений рН. В условиях озер замкнутого стока на юге Западной Сибири оптимальные значения рН для большинства массовых видов зоопланктона составляют 7.5–8.5. Большинство Rotifera, Cladocera и Cyclopoida (за исключением типичных галофилов) не выдерживают уровень солености выше 5 г/л. У представителей отр. Calanoida уровень галотолерантности значительно выше и у некоторых видов превышает 90 г/л.
In the study, the optima and tolerance limits of various zooplankton species in the diverse geochemical conditions of the south of Western Siberia have been calculated. It is shown that in various climatic conditions zooplankton organisms form different limits of halotolerance and adaptability to pH range. In the drainless lakes under study, the optimal values of pH for most mass zooplankton species are within 7.5–8.5. The majority of Rotifera, Cladocera and Cyclopoida do not tolerate salinity above 5 g/l, except for typical halophiles. The halotolerance level of the representatives of the order Calanoida is much higher; for some species, this indicator exceeds 90 g/l.

Проведен мониторинговый эксперимент установления экотопической разницы по накоплению Ni, Zn, Mn, Al, Se, Cs, La и Sm мохообразным Ceratodon purpureus (Hedw.) Brid в условиях антропогенно нарушенной среды Донбасса. Концентрации элементов в гаметофитах растения определены методом нейтронного активационного анализа. Экспозиция образцов проводилась с ноября 2018 г. по май 2019 г. на 24 учетных площадках Центрального Донбасса с разной степенью техногенной трансформации геосистем. Показана разница по накоплению Ni в 6.9, Zn – 10.2, Mn – 6.3, Al – 5.3, Se – 9.6, Cs – 3.9, La – 5.9 и Sm – 5.4 раза при оценке экологически напряженных территорий в сравнении с малонарушенными или восстановленными экотопами. Установлены структурно-функциональные модификации в листовом аппарате бриофита, пригодные для которые рекомендованы для фитомониторинговых исследований в экспресс-диагностике. По результатам факторного анализа были выделены две группы загрязняющих элементов, различающихся по источнику происхождения: в одну из них вошли Al, Ni, Mn, Zn, в другую – Cs, Se, La, Sm. Реализованный опыт рассматривается как элемент первичного скрининга биогеохимических характеристик в Донбассе периода 2018–2019 гг.
The ecotopic difference in the accumulation of Ni, Zn, Mn, Al, Se, Cs, La and Sm in bryophyte Ceratodon purpureus (Hedw.) Brid was studied during a long-term experiment in the anthropogenically disturbed environment of Donbass. The concentrations of elements in moss gametophytes were determined by neutron activation analysis. The moss samples were exposed from November 2018 through May 2019 at 24 test plots in the central Donbass with varying degrees of technogenic transformation of geosystems. When comparing ecologically stressed areas with intact or restored ecotopes, the difference in the accumulation of Ni was 6.9 times, Zn – 10.2, Mn – 6.3, Al – 5.3, Se – 9.6, Cs – 3.9, La – 5.9, and Sm – 5.4 times. There were structural and functional modifications in the leaf apparatus of bryophyte, suitable for using in further phytomonitoring studies for express diagnostics. According to the results of the factor analysis, two groups of pollutants were identified, differing in the source of origin: (1) Al, Ni, Mn, and Zn, (2) Cs, Se, La, and Sm. The obtained data are considered as part of the primary screening of biogeochemical characteristics in the Donbass in 2018–2019. Within the gradient of toxic load and local impact, the leading role of mining and metallurgical facilities in the pollution of natural ecosystems of Donbass was proved.
Interannual dynamics of the Ural River phytoplankton and different-type stretches of the Iriklinsky reservoir in spring
Authors: Джаяни Е.А. , Шашуловская Е.А. 
Published: September 2023

Показано, что ведущая роль в межгодовых изменениях фитопланктона незарегулированного участка р. Урал весной 2016–2019 гг. принадлежала температуре воды и сумме атмосферных осадков, при увеличении которой в воде повышалась концентрация биогенных элементов и органического вещества. В Ириклинском водохранилище развитие фитопланктона зависело от поступления веществ с водосбора, однако степень его воздействия в разных плесах определялась совместным влиянием суммы атмосферных осадков и соотношения основных гидрологических параметров. Благодаря этому в каждом плесе периоды максимального количественного развития сообществ имели временные различия. Фитопланктон исследованных участков отличался разной глубиной трансформации: наибольшее количество статистически значимых изменений изученных показателей характерно для реки и верхнего плеса водохранилища, наименьшее – для нижних плесов, что определялось степенью влияния главной реки и морфометрическими параметрами участков.
Our study revealed that water temperature and total atmospheric precipitation played the leading role in the interannual dynamics of phytoplankton in the unregulated section of the Ural River in spring of 2016–2019. With rise in water temperature, the concentration of nutrients and organic matter increased. In the Iriklinsky reservoir, the phytoplankton development depended on arrival of substances from the catchment, however, the cumulative effect of the ratio of major hydrological parameters and the total atmospheric precipitation was crucial. Due to this, the periods of the maximum quantitative development of the communities in each stretch differed in time. Phytoplankton transformation was diverse and hinged on the influence of the main river, including morphometric parameters of sites. For instance, most statistically significant changes in the studied parameters were recorded in the river and the upper reaches, while the least – in the low reaches of the reservoir.
