Актуальность: Важную роль в лечении женского и мужского бесплодия различной этиологии играют вспомогательные репродуктивные технологии (ВРТ), в рамках которых, проведение молекулярно-цитогенетических исследований супружеских пар, позволяет выявить особенности генотипа, положительно коррелирующие с нарушением репродуктивной функции. Долгое время в проводимых исследованиях не уделялось должного внимания хромосомным полиморфизмам (ХП), так как они не считались клинически значимыми. К настоящему моменту опубликованные научные данные не позволяют сделать однозначного вывода о вкладе ХП в хромосомные аномалии в период раннего онтогенеза, ввиду чего данный вопрос остается дискутабельным и актуальным.
Цель исследования – изучить влияние хромосомных полиморфизмов акроцентрических хромосом (группы D/G) в кариотипах мужчин и женщин на эффективность программ ВРТ.
Методы: Проведено контролируемое одноцентровое ретроспективное исследование эффективности программ ВРТ среди 188 бесплодных супружеских пар с полиморфными вариантами акроцентрических хромосом в кариотипе. Группы пациентов с ХП сравнивались с контрольной группой (557 пар без ХП в кариотипах) по таким критериям, как: частота нормального оплодотворения, качество эмбрионов, процент дорастания до бластоцисты, частота имплантации эмбрионов (ЧИ), частота наступления клинической беременности (ЧНБ), частота ранних потерь беременности.
Результаты: Анализ полученных результатов не показал статистически значимой разницы в количестве полученных на ТВП ооцитов, числе дробившихся эмбрионов и выходе бластоцист отличного качества в группах пациентов с ХП. Также не наблюдалось различий при сравнении частоты нормального оплодотворения и процента выхода бластоцист между группами пациентов с ХП и пациентов с нормальными кариотипами. Однако, выявлена тенденция к снижению ЧИ эмбрионов (44,4 против 49,4%), ЧНБ (54,7 против 58,9%) и увеличению частоты потерь беременности среди пар, в которых хотя бы один из партнеров является носителем ХП.
Заключение: Результаты исследования показали, что ХП группы D/G приводят к снижению эффективности программ ВРТ, негативно влияют на такие параметры, как ЧИ, ЧНБ и увеличивают ранние потери беременности. Полученные данные подтверждают важность проведения кариотипирования пациентов с целью выбора наиболее эффективного метода лечения ВРТ.

Актуальность: В условиях продолжающейся пандемии COVID-19 появляется все больше женщин, уже перенесших это заболевание в разные сроки гестации, с разной степенью тяжести и объемом терапии в острый период, поэтому важным направлением исследований должно стать именно наблюдение за развитием плода, течением беременности и перинатальными последствиями у этого контингента пациенток. Пока таких исследований крайне мало, и они касаются только отдельных состояний – частотыпреждевременных родов и замерших беременностей, пороков развития у плодов, состояния фетоплацентарного комплекса (плацента, околоплодные воды, состояние плода и т.д.).В этом контексте не вызывает сомнений актуальность исследований влияния COVID-19 (SARS-CoV-2) на здоровье беременной женщины, внутриутробного плода и новорождённого.
Цель исследования – анализ современных данных о влиянии COVID-19 (SARS-CoV-2) на особенности состояния внутриутробного плода, возможных путей инфицирования анте-, интра- и постнатально, а также прогнозирование направлений и перспектив будущих исследований.
Материалы и методы: Для обзорабылпроведенпоиск научной литературы за последние 2 года в PubMed по следующим ключевым словам: «внутриутробный плод», «вертикальная трансмиссия COVID-19 (SARS-CoV-2)».
Результаты: Во второй части статьи изучены вероятность инфицирования и распределение случаев по степени тяжести перинатальных последствий. Рассмотрены теории патогенеза акушерских и плодовых осложнений инфекции во время беременности. Очерчен круг потенциальных дальнейших научных изысканий.
Заключение: Анализ доступных источников выявил отсутствие единой классификации болезни COVID-19 и связанных с ней осложнений у беременных и новорожденных. Поэтому важной задачей для системы здравоохранения является разработка единой национальной терминологии и классификации болезни COVID-19 при беременности.
Крайне необходимы дальнейшие исследования влияния COVID-19 на беременность. Неотложной необходимостью является создание национальных реестров случаев беременности у женщин с COVID-19, внедрение единой терминологии и алгоритмов диагностики и лечения COVID-19 и вызванных им осложнений у беременных и новорожденных.
Исследование возможных негативных последствий COVID-19и разработка соответствующих лечебно-профилактических мероприятий является, несомненно, крайне важной задачей для акушерской науки. Отдельным направлением исследований должно стать изучение состояния здоровья, течение беременности и перинатальные последствия у вакцинированных женщин.

Abstract
NASA’s Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, at around 23:14 UTC on 2022 September 26, causing a reduction in its orbital period that will be measurable with ground-based observations. This test of kinetic impactor technology will provide the first estimate of the momentum transfer enhancement factor β at a realistic scale, wherein the ejecta from the impact provide an additional deflection to the target. Earth-based observations, the LICIACube spacecraft (to be detached from DART prior to impact), and ESA’s follow-up Hera mission, to launch in 2024, will provide additional characterizations of the deflection test. Together, Hera and DART comprise the Asteroid Impact and Deflection Assessment cooperation between NASA and ESA. Here, the predicted dynamical states of the binary system upon arrival and after impact are presented. The assumed dynamically relaxed state of the system will be excited by the impact, leading to an increase in eccentricity and a slight tilt of the orbit, together with enhanced libration of Dimorphos, with the amplitude dependent on the currently poorly known target shape. Free rotation around the moon’s long axis may also be triggered, and the orbital period will experience variations from seconds to minutes over timescales of days to months. Shape change of either body, due to cratering or mass wasting triggered by crater formation and ejecta, may affect β, but can be constrained through additional measurements. Both BYORP and gravity tides may cause measurable orbital changes on the timescale of Hera’s rendezvous.

Published: July 2022

Since the beginning of subterranean biological research, the development of underground laboratories has provided scientists with protected places to perform long-term studies and to collaborate with others across subjects. However, aided by advances in technology for research centres and universities and by concerns for the conservation of natural subterranean environments, mots of past subterranean laboratories went under the radar of the institutions that owned them.
Here we describe a new underground facility that was built in Italy by the Regional Park of “Monte Barro” (Lecco, Lombardy) and dedicated to the memory of Enrico Pezzoli who was strongly active in the study of spring and cave biodiversity.
The laboratory has been established by repurposing an ancient draining gallery of the Park; it has been conceived to study local fauna, especially that of local aquifers. Removable equipment has been set stretching along the gallery, from the beginning to deep sections, creating distinct sectors with different conditions allowing to rear, study and compare both troglophile and troglobiont species. In every sector of the laboratory independent blocks with different controlled conditions of light and biotic features can be easily placed and used to rear individuals of both invertebrates and amphibians. Experimental activity does not prevent the exploitation of the gallery by local fauna, with spiders, crustaceans and amphibians usually occurring.
The first experiences performed in the new resource suggest that subterranean laboratories, if appropriately conceived, may represent sustainable facilities thanks to their low energetic requirements and their strong potential in integrating research and education.
The roles of landscape of fear and light in allowing the exploitation of spring habitats by subterranean amphipods: an experimental and field approach

Border habitats such as interfaces and ecotones promise research targets from an evolutionary and zoological point of view. Springs are typical ecotones that border two strongly distinct environments: surface and underground. They are exploited by both subterranean and surface species for which they may provide specific environmental pressures promoting phenotypic plasticity and local adaptations.
The aim of this study is to understand how the landscape of fear (LOF) and physical constraints, like light occurrence, affect springs' exploitation by both a subterranean (Niphargus thuringius) and a surface crustacean amphipod species (Echinogammarus stammeri).
From March to May 2021, we surveyed 15 springs, divided into 25 plots according to their distance to the border, and both day and night, we recorded amphipods activity and LOF levels for them. In a subterranean laboratory, we also reared 80 N. thuringius and 80 E. stammeri in safe and risky conditions with constant darkness and diel light variation assessing their activity and survival for 30 days. Risky conditions were represented by meso-predators (four fire salamander larvae) alone or with a top-predator (a dragonfly larva of the species Cordulegaster boltonii).
While in field conditions, the activity of N. thuringius seemed negatively affected by the number of active predators, in laboratory experiments, the main role was played by the light treatment; activity was significantly higher in constant darkness conditions.
E. stammeri activity in the field was higher in surface plots, while in laboratory conditions was affected by LOF. Predation risk negatively affected the survival of both amphipods.
Our findings reveal that while light conditions seem to shape activity patterns of stygobionts strongly, predators have a lower effect on activity, even though predators have negative effects on survival. Moreover, physical constraints, such as light exposure, can affect antipredator responses of subterranean organisms, thus representing selective pressures for the exploitation of surface environments.
Groundwater invertebrates and droughts: resistance in stygobiont isopods and planarians

In surface freshwater habitats water level can be strongly variable and benthic invertebrates are usually adapted to cope with hydrological variability. Groundwater habitats are usually more stable, even if in sites at the interface with the vadose zone, in epikarst streams and dripping pools hydroperiod may vary. Adaptations to survive droughts are thus likely to have been developed also by groundwater-dwelling animals. However very few studies have been performed to assess stygobiont resistance to dryness. They involve mainly the amphipods of the genus Niphargus and Stygobromus; one case is reported for a triclad of the genus Atrioplanaria.
Here we describe cases of resistance to drying in stygobiont planarians of the genus Dendrocoelum and the in the isopod Monolistra pavani.
Since 2016 we performed multiple surveys in 53 caves in Italy and Switzerland, sampling different stable and unstable groundwater environments. Stygobionts were searched visually and by distressing the substrate. When we detected stygobionts in dry sectors of a cave, we observed their features and behaviours, we pictured them, and we tried to rinse them. We rinsed M. pavani individuals in small plastic tanks and recorded the time of reactivation.
During the surveys we recorded a Dendrocoelum planarian encapsulated in a thick mucus layer on the substrate of a dry subterranean stream. When placed in water the planarian started gliding slowly and reached a length of 18 mm. During the drought of January-April 2022, we detected individuals of M. pavani in dry areas of two different caves. 72% of the individuals were able to reactivate. Time to reactivate ranged between 0 s to 30 s. We recorded living M. pavani individuals that were able to reactivate themselves even after 39 days of drought.
Our observations provide new insights into the natural history of groundwater-dwelling invertebrate taxa which global climatic changes increase the risk of drought occurrence in subterranean environments.
Biology Students Association as the base for establishing future experts and cave fauna exploration

Published: July 2022

Biology Students Association – BIUS (BIUS) from Zagreb, Croatia is a non-government and non-profit association founded in 1999 by biology students from the Faculty of Science, University of Zagreb. Aiming to develop future experts in different fields of biology, BIUS is composed of groups that specialize in various subject areas. Besides holding diverse science lectures, workshops, and field trips, the main BIUS' activities are annual student research camps with the participation of up to 130 members.
An integral part of BIUS from the very beginning is the Biospeleology group (Group). During these first 23 years of the Group's existence, many members discovered their interest in cave biology through field research, cabinet work, and educational workshops. The Group organized two student research camps and participated in 16 others. In addition, the Group organized seven independent projects. Throughout all of these projects, cave fauna was collected from over 150 caves and pits at different localities of Croatian karst. The Group's long-term existence is facilitated by the guidance of mentors from the Croatian Biospeleological Society. Altogether, the Group provides numerous skills and valuable opportunities to students and is important for developing future scientific experts in cave biology in Croatia.
So far, 12 Group members have written their master thesis and four have their doctoral thesis in the field of cave biology. Former members currently work at universities, research institutes, government, and civil sector, or as entrepreneurs on topics closely related to cave biology and karst research.
Prophète ou alter Christus ? Vincent Ferrier au miroir d’estampes du xviie siècle
Authors: Rousseau Claire 
Published: July 2022

Durant sa vie, saint Vincent Ferrier fut un prêcheur mystique, impliqué également dans la résolution de conflits locaux, nationaux ou internationaux et œuvrant pour la paix et l’unité. Pour comprendre son influence, l’approche traditionnelle consiste à analyser sa biographie et ses écrits. Mais l’iconographie du saint exprime également comment sa figure fut promue par les frères de l’Ordre des Prêcheurs et comment elle fut perçue. Le présent article se donne pour but d’examiner le déploiement de son image dans les estampes françaises et flamandes du xviie siècle, siècle d’or de la gravure au burin. Si l’iconographie reste traditionnelle, les estampes s’inscrivent en deux catégories : d’une part, les images de dévotion et les illustrations d’ouvrages, et d’autre part les vies en planches. Ces dernières construisent un discours visuel qui confère à saint Vincent un exceptionnel statut de prophète des derniers temps, voire d’alter Christus.
Le culte d’un saint comme outil politique du temps présent : la Grande Guerre de Vincent Ferrier
Authors: Le Gall Erwan 
Published: July 2022

Les commémorations organisées en 1919 par l’évêque de Vannes pour le 500e anniversaire de la mort de saint Vincent Ferrier sont d’un grand intérêt pour qui s’intéresse au complexe processus de sortie de la Première Guerre mondiale. Non seulement elles viennent rappeler quel redoutable acteur politique est Mgr Gouraud, mais elles invitent à reconsidérer la portée du consensus national qui s’exprime lors de l’été 1919. Si celui-ci est clairement perceptible lors des cérémonies patriotiques et lors des fêtes données pour le retour des régiments victorieux, tel n’est en revanche pas le cas lorsqu’est célébré le prédicateur valencien. Ce faisant, s’impose l’idée d’une Union sacrée qui serait avant tout affaire de moment politique.
Renouvellement de l’écriture autobiographique dans les pas de la littérature prolétarienne suédoise : l’exemple des journaux de Susanna Alakoski
Authors: Pagès Laurent 
Published: July 2022

Cet article met en lumière une tendance forte parmi les écrits autobiographiques des vingt dernières années en Suède : celle qui hérite des écrivains prolétariens qui ont marqué l’histoire littéraire du pays. Il s’appuie principalement sur l’exemple des journaux de l’écrivaine Susanna Alakoski, Oktober i Fattigsverige (Octobre dans la Suède de la pauvreté, 2012) et April i Anhörigsverige (Avril dans la Suède des proches, 2015), pour montrer comment cet héritage se transmet dans un genre que l’autrice renouvelle afin de trouver de nouvelles manières de dire l’itinéraire d’une femme transfuge de classe et venue d’ailleurs dans une écriture orientée vers le collectif et le politique.
Work-Family Conflict and Family Role Performance Among Collegiate Athletic Trainers
Authors: Singe Stephanie M. , Rodriguez Melanie , Cairns Alexandrya , Eason Christianne M. , Rynkiewicz Kelsey 
Published: July 2022

ABSTRACT

Context:
Work-life balance continues to be a focal point of athletic training research, particularly due to the job challenges and demands of healthcare providers. Despite a large body of literature, much is still unexplored, especially in the area of family role performance.

Objective:
Examine the relationship between work-family conflict (WFC), family role performance (FRP) and various demographic variables among athletic trainers employed in the collegiate setting.

Design:
Cross-sectional online survey.

Setting:
Collegiate setting.

Patients or Other Participants:
586 collegiate athletic trainers (females=374, males=210, gender variant/non-conforming=1, preferred not to answer=1).

Main Outcome Measure(s):
Data were collected through an online survey (Qualtrics) where participants responded to demographic questions and previously validated WFC and FRP scales. Demographic data were reported and analyzed for descriptives and frequencies. Mann-Whitney U tests were performed to identify differences among groups.

Results:
Participants mean scores were 28.19±6.01 and 45.86±11.55 for the FRP and WFC scales respectively. Mann Whitney-U tests revealed statistically different differences between men and women for WFC scores (U=344667, p=.021). Family role performance was moderately negatively correlated with WFC total score (rs[584] = −.497, p&lt;.001) and predicted WFC scores (b=72.02, t582=−13.30, p=.001). Mann Whitney-U test demonstrated married athletic trainers (47.20±11.92) had statistically significantly higher WFC scores (U=19847.00, p=.003) than those who were not married (43.48±11.78). Mann Whitney U analysis (U=32096.00 p=.001) also found a significant difference between college athletic trainers with children (48.16±12.44) and those without children (44.68±10.90).

Conclusions:
Collegiate athletic trainers experience more WFC with marriage and having children. These findings indicate that time required to raise a family and build relationships may cause WFC due to time incongruencies. Athletic trainers want to engage in their family roles, when this is limited WFC increases.

Published: July 2022

Orientation: Over the past two decades, a new school of thought has emerged that requires investigation into the multidimensional nature of commitment on loyalty.Research purpose: The study explores the extent to which the affective and calculative commitment of retail banking customers is influenced by selected antecedents, on the one hand, and its influence on loyalty on the other.Motivation for the study: Greater knowledge of the factors that influence the affective and calculative commitment of bank customers becomes important to enhance their loyalty in the competitive banking industry of South Africa.Research design, approach and method: The collection of data was secured from 400 retail bank customers through self-administered questionnaires and analysed using descriptive statistics and standard multiple regression.Main findings: Perceived value, customer orientation, and expertise have a significant and positive influence on affective commitment and calculative commitment. Furthermore, affective commitment has a positive and significant influence on calculative commitment, while both affective and calculative commitment have a positive and significant influence on customer loyalty.Practical/managerial implications: The study guides South African retail banks in developing an improved understanding of the importance of commitment (affective and calculative) as a precursor to loyalty in an emerging African market context. Moreover, it emphasises the importance of selected commitment stimuli that influence the future strengthening of the commitment-loyalty link.Contribution/value-add: Through the application of a relationship marketing and social exchange theoretical framework, selected commitment (affective and calculative) stimuli are investigated to uncover their influence on strengthening the commitment-loyalty link.
