Introduction: Embryonic and larval development in sea urchins is highly dependent on maternal nutritional status and on the environmental conditions of the seawater. Objective: To compare the development of Arbacia dufresnii in two different water temperatures and in progeny with varying maternal origins. Methods: We induced A. dufresnii females and males from Nuevo Gulf to spawn, collected the eggs of each female individually (progeny), separated them into two seawater temperatures (12 and 17 °C), and fertilized them. We recorded the percentage of fertilized eggs and embryos per developmental stage according to time, temperature and progeny. We measured larval growth by total length (TL) and midline body length (M) according to time post fecundation (DPF), temperature, and progeny. Results: Temperature did not affect fertilization, but embryo development was faster and more synchronized in the high temperature treatment. The generalized linear models indicate that embryo development depends on a quadruple interaction between the embryonic stage, time (h), seawater temperature and progeny. Larval growth was faster, producing larger larvae at the highest temperature. Larval growth depends on a triple interaction between time (DPF), seawater temperature and progeny. Conclusions: We found a temperature and progeny impact during embryonic and larval development and, in both cases, these factors generate a synergistic effect on developmental timing and larval size. This probably provides a survival advantage as a more rapid speed of development implies a decrease in the time spent in the water column, where the sea urchins are vulnerable to biotic and abiotic stressors.
Analysis of the target group of lactose-free functional foods for product development
Authors: Szabó E. , Szakos D. , Kasza Gy. , Ózsvári L.
Published: April 2021

The aim of this research was to assess the consumer habits of lactose sensitive persons in case of lactose-free products and their other shopping aspects for development of new, dairy-based lactose-free products. The research was based on face-to-face questionnaire survey, and those who declared to be lactose sensitive were analysed. Among them, only half of the women (49.3%) and one third of the men (34.6%) were medically proven lactose sensitive, so more than half of the respondents declared themselves affected on the basis of self-diagnosis. Our results show that reliably regular customers of lactose-free products are women and persons with medical diagnosis, high educational degree, and under the age of 30. The lactose-free consumer group prefers the following product features: lactose-free label; rich in calcium, vitamins, and fibre, and free of carbohydrate, sugar, and gluten. Only two-thirds of lactose sensitive customers (66.7%) consume lactose-free products regularly, so it can be assumed that the level of knowledge of this disease, its treatment, and the importance of lactose-free dairy products among these persons is insufficient. This could be solved with education, advertisement, and other information opportunities.
Identification of ovine-associated staphylococci by MALDI-TOF mass spectrometry

Published: April 2021

The objective of this study was to use matrix-assisted laser desorption ionisation–time of flight mass spectrometry (MALDI-TOF MS) for the identification of ovine-associated staphylococci. Presumptive Staphylococcus isolates were recovered from ovine udder surface (US), individual raw milk, bulk tank milk, and cheese samples and were characterised by conventional phenotypic methods. A total of 69 bacterial isolates were further confirmed by MALDI-TOF MS. Forty-two (60.9%) of 69 isolates were successfully identified on genus and species level. Two thirds (n = 28) of the 42 identified isolates were shown to be Staphylococcus spp. These 28 staphylococcal isolates formed two clusters, one consisting of 22 Staphylococcus aureus strains and the other composed of 6 non-aureus staphylococci, including S. simulans (n = 3), S. auricularis, S. equorum, and S. haemolyticus. MALDI-TOF MS has proven to be a reliable tool for the identification of staphylococci from raw sheep's milk, especially bulk tank milk; however, currently it appears to be less useful for the identification of bacterial isolates originating from ovine US samples. This is the first study to evaluate the applicability of MALDI-TOF MS for identification of Staphylococcus spp. in ovine raw milk, cheese, and US samples in Hungary.
Substitution of potassium sorbate preservative by fermented wheat flour in the production of biscuits. Safety, nutritional and sensory characteristic potentials
Authors: Fink R. , Filip S.
Published: April 2021

In this study, the potential of the substitution of the conventional preservative potassium sorbate by fermented wheat flour as an alternative was analysed. The organic acid content and antibacterial activity of preservatives and the macronutrient characterisation were tested, as was the sensory evaluation of biscuits with added conventional and alternative preservatives. The results show that the fermented wheat flour contains secondary fermentation metabolites (e.g. acetic, lactic and pyruvic acids). Both fermented wheat flour and potassium sorbate have antibacterial effects against Staphylococcus aureus, Bacillus cereus and Bacillus subtilis. The sensory evaluation demonstrated that fermented wheat flour in the recommended concentration range had no impact on sensory quality. Therefore, fermented wheat flour represents a potential substitution for conventional potassium in bakery products.
Antibacterial efficacy of ethyl pyruvate treatment against Escherichia coli O157:H7 and Salmonella Typhimurium on cherry tomatoes
Authors: Ucak Ozkaya G. , Besir A. , Metin E. , Durak M.Z.
Published: April 2021

Cherry tomatoes inoculated with Escherichia coli O157:H7 and Salmonella Typhimurium were treated with vaporised ethyl pyruvate (EP). The changes of microbial and organoleptic properties of the samples during storage were investigated at two temperatures (4 and 10 °C) and four EP concentrations (0, 42, 105, and 420 ppm) for 7 days at 4 °C and for 5 days 10 °C. After 3 days, 4.3 log and 3.6 log reductions in E. coli O157:H7 numbers were detected in cherry tomatoes treated with 42 ppm EP at 4 °C and at 10 °C, respectively. The highest EP treatment (420 ppm) led to 5.7 log CFU g−1 E. coli O157:H7 reduction after 1 day at 4 and 10 °C. The reduction of Salmonella Typhimurium on samples treated with 420 ppm EP was 7.7 log CFU g–1 after 1 day at 4 °C, and 6.9 log after 1 day at 10 °C. The treatment of EP can be effective at decreasing pathogen populations and can protect the organoleptic and colour properties of fresh produce.
A potential role for psilocybin in the treatment of obsessive-compulsive disorder
Authors: Jacobs Edward
Published: April 2021

The recent revivification of interest in the therapeutic use of psychedelics has had a particular focus on mood disorders and addiction, although there is reason to think these drugs may be effective more widely. After outlining pertinent aspects of psilocybin and obsessive-compulsive disorder (OCD), the current review summarizes the evidence indicating that there may be a role for psilocybin in the treatment of OCD, as well as highlighting a range of potential therapeutic mechanisms that reflect the action of psilocybin on brain function. Although the current evidence is limited, that multiple signals point in directions consistent with treatment potential, alongside the psychological and physiological safety of clinically administered psilocybin, support the expansion of research, both in animal models and in further randomized controlled trials, to properly investigate this potential.
Psychedelic-assisted psychotherapy for depression: How dire is the need? How could we do it?
Authors: Earleywine Mitch , De Leo Joseph
Published: April 2021

Despite the popular support for psychedelics as aids for depression, academics and the public frequently overestimate the efficacy of available medications and psychotherapies. Metaanalyses reveal that antidepressant medications alone help only one in four patients and rarely surpass credible placebos. Their effects, though statistically significant, might not impress depressed patients themselves. Psychotherapies create better outcomes than antidepressant drugs alone; combining the two provides measurable advantages. Nevertheless, the best combinations help only 65% of the clients who complete treatment. The drugs create side-effects and withdrawal surprisingly more severe than professional guidelines imply, too. Psychedelics appear to improve depression through some of the same mechanisms as psychotherapy, as well as some novel ones, suggesting that the combination could work very well. In addition, subjective experiences during the psychedelic sessions covary with improvement. Guiding clients to focus on these targeted thoughts and feelings could improve outcome. These data underscore the serious need for clinical trials of psychedelic-assisted, empirically supported treatment for depression with guided experiences during the psychedelic session. These trials would require important components to maximize their impact, including meaningful preparatory sessions designed to enhance motivation and explain empirically supported approaches, guided administration sessions that focus on oceanic boundlessness, integration sessions that support progress, and follow-up sessions consistent with established research. This combination involves markedly more than a simple pairing of medication and talk therapy, but proper application could have an unparalleled impact on public health.
Passive system optimization in office buildings using a reference testbed building
Authors: Bonjar Mohammad Reza Ganjali , Horváth Kristóf Roland , Baranyai Bálint , Kistelegdi István
Published: April 2021

The purpose of this research is the application of a passive design strategy for office buildings, the wall-window-ratio optimization under moderate climate. A simplified thermal and lighting simulation model of an office research building served as reference testbed for thermal comfort, daylight factor and illuminance as well as heating, cooling and lighting energy demand assessment. These six performance types of similarly oriented room groups are evaluated via a self-developed weighting process to determine the orientation dependent optimal wall-window-ratio of all room groups. This multi objective optimization applies in a broad range of office buildings under moderate climate.
Discovery of the Australian diving beetle Neobidessodes mjobergi (Zimmermann, 1922) in New Guinea (Coleoptera, Dytiscidae, Hydroporinae)
Authors: Surbakti Suriani , Balke Michael , Hendrich Lars
Published: April 2021

The diving beetle genus Neobidessodes Hendrich & Balke, 2009 contains 10 species. Nine of them were considered endemic to Australia, one of them to the Trans Fly Savanna and Grasslands Ecoregion of New Guinea island. Here, we provide the first report of one of the Australian species, Neobidessodes mjobergi (Zimmermann, 1922), from the same region of New Guinea. We suggest that more focused research will reveal the occurrence of far more Australian diving beetle species in that region of New Guinea.
From Militants to Secret Agents: Ukrainian Communists under General Denikin
Authors: Aunoble Éric
Published: April 2021

During the Civil War, the Communist Party and its activists had to constantly adapt to ever-changing situations. This paper aims to study their reaction in Ukraine in 1919 after Denikin took control of the country. It will focus on the 800 activists sent behind enemy lines from July to November 1919. Using the paperwork of special bodies created by the Central Committee (CC) of the Communist Party (Bolshevik) of Ukraine (CP(b)U) to tackle this task (Zafrontbyuro – rearguard bureau; Voenotdel – military department; Otdel Svjazi – communications department), the article will first question the way underground activists were selected. Second, it will highlight how missions behind enemy lines were designed and organized. Third, it will consider the missions themselves and the hardships endured once activists reached Denikin-controlled territory. Fourth, one has to wonder what activists tried to do, questioning what they thought about their dangerous job and what their missions effectively brought to the Bolsheviks. This will help us understand how the Civil War was indeed a “formative experience” (in Sheila Fitzpatrick’s words) for the communists, shaping their worldview and behavior.
The Ukrainian People’s Gromada in the Civil War: Ukrainian Conservatives, Russian Statists, or Little Russian Patriots?
Authors: Chemakin Anton
Published: April 2021

This article is devoted to the Ukrainian People’s Gromada (UPG), the organization of Little Russian landlords which played a prominent part in the political life of Ukraine and South Russia during the Civil War. Ukrainian historiography treats the UPG as an organisation of Ukrainian conservatives and assigns it the key role in the Hetman coup d’état of April 1918. There is also a widespread opinion that the Gromada was dissolved immediately after Hetman P. P. Skoropadsky took power. This work aims to reconsider traditional views on UPG and, with reference to new archival sources, prove the following: the role of the Gromada in the coup d’état was exaggerated considerably; the UPG continued to exist after Skoropadsky took power; and one can doubt the “Ukrainian” nature of the organisation, despite its name. Based on Skoropadsky’s memoirs and the accounts of other witnesses, as well as some German sources, the author proves that the Gromada was not the leading force in the coup d’état, but only the organisation which prepared lists of candidates to be included in the new government. The sources kept in the Central State Archives of the Supreme Bodies of Power and Government of Ukraine and the Hoover Institution Archives that are devoted to the activities of the UPG from the summer of 1918 to the spring of 1919 have not been made public previously. After the directorate seized power, the leaders of the Gromada fled from Kiev to Odessa. There they took part in local political intrigues and tried to distance themselves from Hetman Skoropadsky and the project of the Ukrainian state. The UPG leaders, who had previously viewed themselves as Ukrainian “samostiyniks”, now proclaimed that they were not Ukrainians, but Little Russians and “Russian statists”. An attempt is made to analyse the reasons why UPG members moved from the Russian political camp to the Ukrainian one and back several times in a comparatively short period. Based on research in the field of “nationalism studies”, the author concludes that the Gromada members had traditional, pre-modern views on the nation (in this case as a corporation of Little Russian nobility), which, together with their desire to adapt to the ever-changing political situation and fight for their privileges and economic interests, made it possible for them to keep joining Russian and Ukrainian nationalists interchangeably without perceiving their actions as national treason. The study of this topic makes it possible to address the Little Russian nobility’s behaviour in the Civil War and their attempts to integrate into Ukrainian or Russian national projects.
The Russian Red Cross in the Civil War
Authors: Fayet Jean-François
Published: April 2021

Based on Russian and non-Russian materials, this article examines the history of the Russian Red Cross Society during the Civil War. The ascension of the Bolsheviks to power led to the breakup of the Russian Red Cross Society (RRCS) into a multitude of national and political associations, each claiming its material and symbolic heritage. When the Civil War began, these fragments of the RRCS no longer existed as effective sanitary organisations. But in autumn 1918, as epidemics threatened troops and civil populations alike, RC institutions had to be set up again urgently. In view of their experience and infrastructure, the Moscow, Omsk, and Kiev RC organisations quickly became decisive players in the Civil War with the Red Army and the White armies of Kolchak, Denikin, and Wrangel. In many fields, these RC organisations acted as a substitute for the state. They were responsible for nursing, nutrition, and evacuation. On the external front, the material assets of the former RRC had to be recovered, Russian soldiers arrested abroad assisted, and the exclusivity of the RC emblem defended. In conclusion, this article argues that the Russian Civil War was a dramatic theatre of modern humanitarian action for the entire international RC movement (the International Committee of the Red Cross and the League of Red Cross Societies) in terms of the practices and laws that had to be invented. Given its fragmentary nature, the mix of identity, social, and ideological conflicts, the civilian populations in the foreground, and the intermingling of national and international players, the Russian Civil War was a forerunner of the “new wars” of the late twentieth century.
Peter the Great as Antichrist: The Secular Sources of an Old Believer Compilation from Holy Scripture
Authors: Perrie Maureen
Published: April 2021

This article is devoted to an Old Believer work about Peter the Great, known as A Compilation from Holy Scripture about the Antichrist, which was first published in 1861. Some scholars have suggested that the work dates back to Peter’s reign, when many traditionally minded Orthodox Christians regarded the tsar as the Antichrist. The author of this article argues, however, that the work dates from the early nineteenth century, and that the case it makes for Peter’s identity as Antichrist is based primarily on tales about the tsar which were published in the late eighteenth century. On the basis of anecdotes about Peter’s conception, for example, the author of the Compilation drew a comparison with the Annunciation, the Epiphany, and the Feast of the Circumcision, to demonstrate a sacrilegious parallel between Peter’s biography and that of Christ, which “proved” that Peter was the Antichrist. The Compilation also cites works which seem to blasphemously suggest that Peter was God incarnate, in order to argue that the tsar was the embodiment not of God, but of Satan. Finally, when one work praised Catherine the Great for representing “the spirit of Peter the Great”, the compiler concluded that the spirit of all subsequent Russian rulers was also the spirit of Peter, that is, the spirit of the Antichrist. This is an idiosyncratic version of the argument made in the late eighteenth century by Evfimii, the founder of the Old Believer sect of the beguny, that Peter had founded a dynasty of Antichrists, and that all “true Christians” should flee from his realm. The distinguished Russian scholars Viktor Zhivov and Boris Uspenskii have argued that the metaphorical sacralisation of the monarch, in secular eighteenth-century panegyrics, was interpreted literally by some Old Believers and contributed to their identification of Peter as the Antichrist. The author of this article suggests that a similar role was played by more popular works such as the collections of anecdotes which presented the tsar as a God-like figure.
Politics in the Non-Political: The Ideology of Constitutional Reforms in Professional Congresses in the Early 20th Century
Authors: Tumanova Anastasia , Safonov Alexander
Published: April 2021

This article considers congresses organised by representatives of various professions (technicians, doctors, teachers) on the eve of the First Russian Revolution. Based on documents from the four most important and populous public meetings, the authors conclude that they turned into a meeting place for non-zemstvo intellectuals with public figures from the zemstvo movement, which led to the emergence of a political class. The purpose of this article is to describe the evolution that the congresses underwent based on the analysis of congress documents (meeting records, reports, resolutions, etc.), periodicals, and political investigations covering their work. It is demonstrated that congresses ceased to be reviews of achievements of certain branches of the national economy (science and technology, medicine, and public education), which were meant to confirm the recognition of their significance by the state. Instead, they turned into demonstrations of the independent position of professional figures on issues of professional and socio-political agenda, into channels for mobilising public opinion in the direction of constitutional reform of the autocratic system and ideological preparation for the First Russian Revolution. The congresses promoted the involvement of the community outside the zemstvo in transforming the bureaucratic system into a legal state and class-based Russian society into civil society. On the eve of 1905, public congresses were an important milestone in the development of the liberation movement in Russia and symbolised its transition to so-called “new liberalism”. It was characterised by overcoming the monopoly position of zemstvo activists in the liberal movement and involving various professional groups in Russian society, mobilising public opinion to discuss public participation in political decision-making. According to the authors, professional forums were historically significant as they had an impact on the ruling elite: they let it know about public ideas concerning urgent socio-political transformations and ensured public participation in the development of strategies for their implementation. Professional congresses lie at the intersection of several areas of modern historical knowledge: political and social history, the history of ideas, and the history of professions. However, they have not been studied comprehensively so far, and the authors fill this historiographical gap.
Feeding habits of the Robber Frog Pristimantis paulodutrai (Bokermann, 1975) in northeastern Brazil
Authors: Alves-dos-Santos Thales Francisco S. S. , Forti Lucas Rodriguez , Napoli Marcelo Felgueiras
Published: April 2021

Abstract: Studying feeding habits is crucial to understand complex predator-prey interactions. Even though anurans play a fundamental role in the control of arthropods populations, the diet of several Neotropical species is poorly known. We describe the frequency and occurrence of prey items and their dry mass in stomach contents of the Robber Frog Pristimantis paulodutrai in the north east of the state of Bahia, Brazil. Based on the stomach contents of 30 individuals, Araneae, Isopoda, and Formicidae were found to be the most important food items. The generalist diet of this frog, which seems to be phylogenetically conserved among Pristimantis, is likely to be linked to its ecological dominance in the habitats surveyed. Our study corroborates the high trophic relevance of Robber Frogs in tropical forests as generalist predators.

Published: April 2021

ABSTRACT Objective: to analyze the association between Burnout, stress, mental suffering and other personal and work factors associated with this syndrome. Method: cross-sectional, descriptive and correlational study with 282 health professionals from the emergency services of the city of Ribeirão Preto, Brazil, collected from October 2015 to March 2016. The instruments used were: sociodemographic questionnaire, Maslach Burnout Inventory, Childhood Trauma Questionnaire, Stress Symptom Inventory, Perceived Stress Scale, Psychiatric Screening Questionnaire, Fantastic Lifestyle Checklist, Hospital Anxiety and Depression Scale and Holmes-Rahe Social Readjustment Rating Scale. Descriptive writing of the data. Pearson's Chi-Square or Fisher's Exact Tests to check the association between variables and later regression analysis, in which ORs were calculated, with 95% CI and 5% significance level. Results: there was statistical evidence of an association between Burnout and education, early stress, stress, common mental disorders, lifestyle, anxiety and depression. The regression analysis shows that the variables that influence Burnout are: type of service (p=0.032; OR=0.187), education (p=0.029; OR=2.313), perception of stress (p=0.037; OR=1.67) and social readjustment (p=0.031; OR=1.279). Conclusion: this study points to a profile for the development of Burnout, consisting of health professionals with higher education, who suffered early stress, who have symptoms and perception of stress, who do not have a healthy lifestyle and show symptoms of mental suffering. Such results can assist in the development and implementation of strategies aimed at reducing both work stress and the prevalence of Burnout syndrome.
Biology and bulb production of Eleutherine bulbosa (Iridaceae), a native species from Borneo, Indonesia

Published: April 2021

Abstract Eleutherine bulbosa is a known ornamental plant of the Iris family, which originated from Central Borneo, Indonesia. The bulbs of E. bulbosa have long been used as a medicinal source by the local people of Borneo. Despite its known medicinal and other values, studies on the morphology and efficiency in bulb production of this species are limited. The aims of our study are to examine the vegetative and reproductive morphology of E. bulbosa, and to determine the effect of various dosages of NPK fertilizer on flowering and bulb production. The plants were grown in pots using potting mix consists of equal volume of burnt rice hulls, cocopeat, and organic manures (1:1:1). Our study showed that E. bulbosa has a cymose rhipidium inflorescence with 25-50 mm long peduncles, have 3-4 umbel on the secondary axis, each consists of 10-12 florets that opens in turn every day. Florets are 20-30 mm long, 20 mm in diameter, 10-15 mm pedicels, and short-lived. The perianth is white, about 25 mm wide with yellow anthers and stigma. Fruits were not formed during the duration of the study. NPK fertilizer application at the lowest dose of 1 g per pot had promoted earlier shoot emergence and vegetative growth, including plant height, leaf number, leaf size, number of tillers, and bulb production compared to control (no fertilizer). Application of fertilizer at 1 and 2 g per plant significantly promoted earlier flowering, whereas application at 3 g per plant delayed and reduced the proportion of flowering plants. The results of this study can aid in taxonomic identification and efficient cultivation of this plant for uses as potted flowering ornamentals or bulb production for different purposes. Higher cultivation and reduced wild harvesting can result in the conservation of this species.

Published: April 2021

Abstract Orchids are one of the groups of plants with the greatest commercialization potential. They have floral characteristics highly valued in the sector of flowers and ornamental plants. However, exotics species are the most commercialized. The native species are still little explored for their ornamental potential. Thus, this work describes the vegetative and floral morphological characteristics of Schomburgkia crispa Lindl. aiming at evaluating its ornamental potential. For such, seven individuals were chosen. The quantitative characters were evaluated in all plants, totaling fifty pseudobulbs and eighty-eight flowers. During flowering, the most representative plant was chosen for the visual evaluation of its morphological features through photographs. A floral diagnosis sheet based on photos of fresh flowers was prepared by keeping the maximum level of morphological details. At the end of the experimental period, averages and standard deviations were calculated for each character evaluated. The species S. crispa presented, on average, plants 46.17 cm long, 31.50 cm wide, and with 88 cm of diameter. For flowering characters, the species presented in general 16.50 flowers per plant, 14.67 per flower stem, and 4.66 flowers opened per day, with an average durability of 32 days. Thus, we conclude that the species S. crispa has a great ornamental potential for use in ornamental horticulture.
Binary alkali-activated systems obtained by the valorisation of calcined kaolin sludge and bottom ash
Authors: Longhi Márlon A. , Rodríguez Erich D. , Bernal Susan A. , Provis John L. , Kirchheim Ana Paula
Published: April 2021

This paper assesses the use and valorisation of two industrial wastes generated at a large scale, which are currently disposed in landfills, as raw materials to produce geopolymers. Specifically, a kaolinitic sludge from the mining industry (CKS), and bottom ash (BA) generated during coal combustion in a thermal power station, were used as aluminosilicate precursors in geopolymer synthesis. The geopolymers were synthesised at 50°C, with a sodium oxide/aluminium oxide (Na2O/Al2O3) molar ratio of 1.0, and different silica/aluminium oxide (SiO2/Al2O3) molar ratios adjusted by manipulating the content of the soluble silicate solution used as the activator. The mechanical strength and reaction products formed during the geopolymerisation process were assessed up to 90 days of curing. The use of CKS as the main component of the precursor blend provides a geopolymer with better mechanical properties due to its higher reactivity than BA. The content of soluble silicates in the alkali activator plays an important role during geopolymerisation, improving the mechanical properties due to the formation of a more reticulated and dense structure. The mortars show a compressive strength higher than 55 MPa after 28 days and low water absorption by capillarity. This elucidates the feasibility of valorising these industrial residues as precursors for geopolymer cements.
Blasting and preconditioning modelling in underground cave mines under high stress conditions
Authors: Córdova E. , Gottreux I. , Anani A. , Ferrada A. , Contreras J.S.
Published: April 2021

Cave mining is an underground mass mining technique. The largest projects, which are known as 'super caves', produce hundreds of thousands of tons of ore per day, which involves large footprints with considerable column height, and have a life of mine of over 20-40 years. These operations are typically located deep, under high stresses and in competent rock masses, making initiation and propagation of the caving process harder to manage. These challenges must be confronted by optimizing the fragmentation of the orebody to achieve smaller size blocks that will result in consistent caving and improved flow of the ore from the drawpoints. To achieve better performance from the drawpoints, preconditioning is applied to fragment and damage the material required to cave. We present a proposed design for preconditioning in underground mines, considering the challenges that these large-scale mines are already facing, based on a comprehensive analysis of current design parameters, case studies, and sensitivity analyses using numerical models.
Everyday issues in women with bleeding disorders
Authors: Skouw-Rasmussen Naja , Pollard Debra
Published: April 2021

Men and women with bleeding disorders have similar symptoms but their experiences are different. It has been shown that women with a bleeding disorder rate their quality of life on a par with that of men with haemophilia who have HIV. Many factors determine quality of life, ranging from delay in diagnosis, to access to treatment and support from family and friends. Women should ask themselves what is important to them and recognise the barriers that determine whether they can achieve their aims in life. Quality of life instruments do not measure the impact of these disorders in a way that is specific to women. Psychosocial health – i.e. the mental, emotional, social, and spiritual aspects of what it means to be healthy – can have a major impact on quality of life. Women with bleeding disorders face a number of challenges to their psychosocial health. They struggle to be believed, they live with guilt, and they may have to fight for the best care for their children. They face obstacles to building relationships and their experiences can leave them isolated. Perhaps because of this, women with bleeding disorders are strong – but they also need to be encouraged to make time for themselves and look after their mental health.

COVID-19’DA KARDİYOTORASİK RADYOLOJİK GÖRÜNTÜLEME VE YAPAY ZEKANIN ROLÜ
Authors: AYYILDIZ Veysel  Atilla

ÖZET

Covid-19'un görüntülemesiyle ilgili bulgular 2020'nin başlarında yayınlandığından beri çok şey öğrenildi. Görüntüleme çalışmalarını bildirmek için birçok sınıflandırma sistemi, karakteristik görüntüleme bulgularına dayanarak geliştirilmiştir. Görüntülemedeki artmış performans ve RT-PCR (Revers Transkriptaz-Polimeraz Zincir Reaksiyonu) testine erişimin kolaylaşması sonucu görüntüleme yalnızca daha şiddetli hastalığı olan veya solunumu kötüleşen hastalar için endikedir. Enfeksiyon, asemptomatik tablodan şiddetli ve bazen ölümcül hastalığa kadar değişen bir spektrumda ortaya çıkmakla beraber, en sık akut akciğer hasarı görülür. Görüntüleme başlangıçta alternatif olarak BT (Bilgisayarlı Tomografi) ile ortaya çıkıp sonradan muhtemelen RT-PCR'na kıyasla daha üstün bir test olarak, spesifik endikasyonlara dayalı daha sınırlı bir rol almıştır. Salgının başlarında, Covid-19 şüphesi olan hastalar için, RT-PCR testinin kullanılabilirliğinin sınırlı olduğu ve performansının belirsiz olduğu durumlarda triyaj amacıyla göğüs görüntüleme için çeşitli sınıflandırma ve raporlama şemaları geliştirilmiştir. Covid-19'a özgü tipik bulgulara sahip özellikler ve alternatif bir tanıyı öneren özellikler için gözlemciler arası anlaşma, çok sayıda çalışmada yüksektir. Göğüs grafisi (GG) ve BT'deki akciğer tutulumunun derecesini değerlendiren bazı çalışmalar, kritik hastalık ve mekanik ventilasyon ihtiyacı ile korelasyon göstermiştir.

Pulmoner belirtilere ek olarak, tromboembolizm ve miyokardit gibi kardiyovasküler komplikasyonlar, bazen nörolojik ve abdominal belirtilere katkıda bulunan Covid-19'a atfedilmiştir. Son olarak yapay zeka, hem radyografi hem de BT açısından Covid-19 pnömonisinin hem tanı hem de prognozunda umut vadetmektedir.
Covid-19 Tedavisinde İmmun Plazma Uygulamaları
Authors: NURLU TEMEL Esra
Published: April 2021

Yüzyılda bir yaşanan ve ne zaman sonlanacağı öngörülemeyen şiddetli akut solunum yolu sendromu koronavirüsü-2 (SARS-CoV-2) pandemisi tüm dünyada hız kesmeden devam etmektedir. Umut verici aşı ve ilaç çalışmalarına rağmen pandeminin kontrol altına alınamaması nedeni ile iyileşen hastalardan elde edilen immun plazmanın koronavirüs hastalığı 2019 (COVID-19) tedavisinde uygulanması, alternatif tedavi seçeneklerinden biri olarak güncelliğini korumaktadır. İyileşen hasta plazmalarının salgın hastalıklarda kullanımı yeni bir yöntem olmayıp tarihte birçok bulaşıcı hastalığın tedavisinde kullanılmıştır. İmmun plazma içinde bulunan Nötralizan antikorların (Nab) bilinen etki mekanizması virusun hücre içine girişinin, füzyonunun ve çıkışının engellenmesidir. Plazma tedavisinin erken dönemde (7 gün) kullanılmasının hastalık şiddetini azaltarak hem hastanede kalış süresini kısalttığını hem de sağ kalımı arttırdığını gösteren çalışmalar mevcuttur. Güvenlik ile ilişkili olarak biriken veriler; immun plazma tedavisinin diğer plazma ürünleri ile benzer yan etkilere sahip olduğu yönündedir. İmmun plazmanın, duyarlı kişilerde doğrudan SARS-CoV-2’yi hedefleyebilecek etkili ve hızlı bir tedavi stratejisi olabileceği düşünülmektedir . Bu derlemede güncel veriler ışığında COVID-19 pandemisinde hızla kullanım alanı bulan plazma tedavisi uygulamaları tartışılacaktır.

Authors: ÖZOKCU Osman
Published: April 2021

This study aimed to determine the variables predicting the attitudes of Turkish special education preservice teachers towards the teaching profession. The study was carried out using a relational screening model among the quantitative research methods. The participants of the study consisted of 308 (163 females, 145 males) special education preservice teachers. The research data were collected using the Personal Information Form, Academic Motivation Scale, Life Satisfaction Scale, Professional Self-Esteem Scale, and Teacher Self-Efficacy Scale. The Pearson correlation coefficient and hierarchical regression analysis tests were used to analyze the data. The results of the study demonstrated that the preservice teachers' attitudes were predicted by the variables of professional self-esteem, amotivation, intrinsic motivation, and self-efficacy, while the life satisfaction and extrinsic motivation variables were not significant predictors of attitudes towards the teaching profession
Kronika konjaničkog spomenika Marka Aurelija
Authors: Buntak Marija
Published: April 2021

Rad prati složenu povijest konjaničkog spomenika Marka Aurelija od njegova nastanka do postavljanja na Kapitolijski trg (Piazza del Campidoglio) te suvremenog doba. Proučavanjem povijesnih izvora rasvjetljuje okolnosti pod kojima je skulptura, gotovo dvostruko veća od prirodne veličine, izrađena od bakra na koji je zatim aplicirana pozlata, svojom grandioznošću oduvijek plijenila pozornost i pobuđivala zanimanje stanovnika i posjetitelja Rima.

Julije Klović na medaljama i medaljonu
Authors: Mirnik Ivan
Published: April 2021

Za svog života Juraj Julije Klović portretiran je na medaljama dvaput – ukoliko nije riječ o dvije inačice iste medalje – a samo jedna medalja sačuvana je do danas i to u Odjelu za numizmatiku i medalje Britanskog muzeja u Londonu. Godine 1632. postavljen je u rimskoj crkvi nadgrobni spomenik J. J. Kloviću s mramornim ovalnim medaljonom s portretom velikoga majstora minijature. U drugoj polovini 17. stoljeća neki ne prevješti medaljer napravio je medalju s poprsjem osobe koja profilom ni u kom slučaju ne sliči Kloviću, iako natpis govori suprotno. Tijekom druge polovine 20. stoljeća neki hrvatski medaljeri (I. Belobrajdić, Z. Brkić, A. Kukec, K. Kovačić, D. Mataušić) posvećivali su Kloviću svoje radove, bilo s njegovim portretom, bilo s reminiscencijama na neke od njegovih vrlo brojnih radova.

At the present stage of development and practical application of acupuncture, we are faced with an unusual phenomenon. It lies in the fact that the doctor is involved in reflexology, reveals the nature of the lesions of certain organs with the help of modern methods of diagnostics, which are very different from the Oriental. But on the other hand, the treatment of acupuncture is not very far removed from the level and approaches of the ancient doctors, and the doctors at this stage used the combination of acupuncture points which have been tested by thousand-year practice. This leads to the complexity of the treatment of acupuncture. The authors experience of developing the plan and building an acupuncture prescription based on a modular systematization of acupuncture points. This will allow the doctor to plan treatment for virtually any patient. To avoid mistakes, a template approach is necessary: to evaluate the functional condition of the meridians and acupuncture points, to understand the causes of these violations, form of acupuncture diagnosis on the basis of leading etiopathogenetic mechanism, to develop the baseline treatment. Professionals not proficient in pulse diagnosis, we propose to use prestazioni diagnostics, which allows to evaluate and analyze the effectiveness of reflexotherapy, to adjust the treatment process. In the cycle of U-sin to evaluate the functional state of meridians, to choose the correct technique irritation of acupuncture points.
