Abstract
Waves of COVID-19 have been managed successfully within US, EU, Southeast Asia and Latin America, however, South Asia and Sub-saharan Africa still suffer new variants and EU fights with UK and United States of ,,new waves of old disease“, postcovide or long covide syndrome. The aim of this communication and research is to prepare our auditors for the size and extent of postcovid systems and the importance of non-doctors and non-medicine experts in management of its consequences.

Abstract
Objective: The aim of our research was to determine the distinction between behavioral patterns of refugees versus economic migrants from Ukraine in order to confute widespread Slovak media image of all incoming Ukrainian citizens as severily suffering from war trauma and being at the edge of their financial or material survival.Design: Case Study from the Capital of Slovakia. Participants: Ukrainian citizens living in Bratislava who entered Slovakia at the beginning of the time of the Russian invasion until today. Methods: Analytical evaluation based on a critical approach to media image confronted with real situations regarding refugees versus economic migrants from Ukraine was applied. To grasp the issue of behavior of incoming persons, firstly, naturalistic observation method has been used. Results: Using sensitive and detailed observation the distinction between Ukrainian refugees and economic migrants can be drawn and should be applied on a common basis. This should be based on their behavioral patterns as seen in praxis. Conclusion: Discerning refugees from economic migrants needs to be done in order to ensure fairness towards incoming persons and also locals. The distinction should be based on objective observation of behavioral patterns of all the incoming Ukrainian citizens and based on that decisions of competent institutions and preparation of relevant legislation should be made. It is inevitable to start to grasp the problem of unjust generalizing approach and also to stop antisocial behavior on the streets, in the city transport, at the shops, in the doctor´s waiting room, etc. of incoming Ukrainian citizens, who do not show any signs of war trauma and are obviously economic migrants, moreover, inadaptable. Continuation of peaceful living of locals should be granted by Slovak government both in the form of issuing proper legislation and by immediate implementation of legislation into practice. The Slovak media image of the current situation concerning this matter needs to be straight reconsidered, revised and by these steps to prevent and protect the community from further demage and overall reduction in the quality of life of all the inhabitants of the capital.

Abstract
This current issue of Clinical Social Work and Health Intervention (CSW, 1-5) summarizes the three last issues focused on two devastating events. 1st – the two year pandemics of coronavirus infection originated from Hongkong 2003; via Abu Dhabi 2012; Busan 2017; Wuchan 2019 via Italy, France and large airports and sports/ cultural events to Central and Eastern Europe. 2nd – three war conflicts, two of them in Europe, or very close to the EU: first in 2012-2020 in Yemen due to airstries and infrastructure bombing of Taizz, Sanaa and Hodeida; second in Karabakh, Stepanakert Region by shelling from Azerbajjjan; third in Ukraine after bombing and still permanent shelling from Russian and Russia-satellite allies to Ukraine. We have to face the part played by devastating infrastructure destruction of hospitals schools, socio-economic and industrial damage to health and sanitary with consequences such as has been noted after an earthquake in Haiti and war in Rwanda and DRC. Currently, unfortunately, dealing with destroyed urban infrastructure in Mariopil and other towns, such as cholera outbreaks and Covid 19 resurgence results in massive a flow of refugees of war - a classic example of how socio-economic tragedy is followed by large health catastrophe. The EU is prepared for country rehabilitation including healthcare and educational support. The ultimate condition however is the immediate stopping of armed activities especially bombing and shelling of the water supplies and sanitary infrastructure.

Abstract
Point prevalence studies bring us approximate situations in border emergency settings where longitudinal or comparative studies are not realistic from logistic safety points of view. The one day point prevalence study performed at most frequently used checkpoints between Ukraine (UA) and Slovakia (SK). No case of TB screened by the WHO recommended questionnaire, or HIV performed by rapid test has been noted on day 7 after the war was declared.

Abstract
St. Elizabeth University, Bratislava, and its Tropic team has had an active participation in refugee and migrant humanitarian aid since 2015. In the beginning, it was mainly providing health care in the border areas of Hungary, Serbia, and Slovenia, which represented transit points on the route to Western European final destinations. The uncontrolled influx of fleeing people (mainly Syrians at that time) was stopped in March 2016. The diplomatic EU-Turkey deal and subsequent closure of Balkan borders resulted in an extensive humanitarian catastrophe when thousands ended up stranded in Greece. Since then, the members of St. Elizabeth’s Tropic team operate in affected Greek areas. At first, the University had its presence in the northern part of mainland Greece, which later moved to Lesbos Island. Cooperating closely with the Greek Ministry of Health as well as with multiple non-governmental non-profit organizations registered in Greece. The Topic team focuses on refugee health care inside as well as outside the Greek refugee camps.

Abstract
Thousands of healthcare and social workers (HCSW) died or lost their ability to work in their field after Covid pandemics in all three waves, and thousands left their profession due to burnout syndrome. Despite development of vaccines took 6- 18 months and refreshment of old molecules for treatment weeks, many countries paid a very high price for this pandemics not due to lack of medications or ventilator assistance devices but due to the increasing lack of trained HCSW.

Abstract
Objective: The aim of our research was to find out, if university students of humanities and social sciences at five Slovak public universities have theoretical prerequisites for intercultural competencies mainly needed in multicultural healthcare. These concrete theoretical prerequisites are dealing with knowledge regarding Islamic teachings on: family; female infanticide; reproduction; usage of assisted reproduction technologies; and induced abortion. Design: Research study. Participants: Overall 1000 students at 5 Slovak public universities (at each n=200). Methods: Empirical research was done using our own questionnaire. Verification of our three hypotheses has been done using the method of statistical testing for testing hypotheses on equality of parameters of two alternative divisions with large selection ranges. Results: Responses to questions concerning definition of marriage in Islam (Questions #1 - 3) have shown, that both male and female students have proved better knowledge of this issue than in the case of the area concerning possibilities of use of reproductive medicine achievements in Islam. Responses to question (Question #4) regarding Muhammad´s attitude to feminine infanticide have shown that men, in comparison to women, have manifested more radical (more numerous) inclination to the answer that Muhammad entrusted fathers with decision on its performance. Responses to questions dealing with possibilities to use reproductive medicine achievements in Islam (Questions #5-7) have shown that female, in comparison to male students, have manifested more radical (more numerous) rejective position. Conclusion: Knowledge of marriage and reproductive issues in Islam among students stays at historical level, what causes a problem not to be able to understand and respect contemporary needs of Muslim patients in the frame of an holistic approach in multicultural healthcare and social work in Slovakia. Improvements in current curriculum concerning students´ intercultural competencies mainly connected to an understanding of standpoints of Muslim believers concerning their social foundations, health and entire well-being are inevitable.

Abstract
Studies in vivo have suggested the involvement of CREB-regulated transcription coactivator (CRTC)2 on ACTH-induced transcription of the key steroidogenic protein, Steroidogenic Acute Regulatory (StAR). The present study uses two ACTH-responsive adrenocortical cell lines, to examine the role of CRTC on Star transcription. Here we show that ACTH-induced Star primary transcript, or heteronuclear RNA (hnRNA), parallels rapid increases in nuclear levels of the 3 isoforms of CRTC; CRTC1, CRTC2 and CRTC3. Furthermore, ACTH promotes recruitment of CRTC2 and CRTC3 by the Star promoter and siRNA knockdown of either CRTC3 or CRTC2 attenuates the increases in ACTH-induced Star hnRNA. Using pharmacological inhibitors of PKA, MAP kinase and calcineurin, we show that the effects of ACTH on Star transcription and CRTC nuclear translocation depend predominantly on the PKA pathway. The data provides evidence that CRTC2 and CRTC3, contribute to activation of Star transcription by ACTH, and that PKA/CRTC-dependent pathways are part of the multifactorial mechanisms regulating Star transcription.

Abstract
Circadian and ultradian variations of basal glucocorticoid secretion and transient elevations during stress are essential for homeostasis. Using intronic qRT-PCR to measure changes in primary transcript (hnRNA) we have shown that secretory events induced by stress or ACTH injection are followed by episodic increases in transcription of rate limiting steroidogenic proteins, such as steroidogenic acute regulatory protein (StAR), cytochrome P450 side chain cleavage and melanocortin receptor associated protein. These transcriptional episodes imply rapid turnover of steroidogenic proteins and the need of de novo synthesis following each secretory event. In addition to episodic ACTH secretion, it is likely that intracellular feedback mechanisms at the adrenal fasciculata level contribute to the generation of episodes of transcription. The time relationship between activation and translocation of the CREB co-activator, transducer of regulated CREB activity (TORC) to the nucleus preceding transcriptional episodes suggest the involvement of TORC in the transcriptional activation of StAR and other steroidogenic proteins.

Abstract
Microglia, the tissue macrophages of the brain, have under healthy conditions a resting phenotype that is characterized by a ramified morphology. With their fine processes microglia are continuously scanning their environment. Upon any homeostatic disturbance microglia rapidly change their phenotype and contribute to processes including inflammation, tissue remodeling, and neurogenesis. In this review, we will address functional phenotypes of microglia in diverse brain regions and phenotypes associated with neuroinflammation, neurogenesis, brain tumor homeostasis, and aging.

Abstract
MTD-PLS, the Partial Least Squares (PLS) variant of the Minimum Topological Difference (MTD) method is described. In MTD-PLS, molecules are characterised not only by the occupancy or nonoccupancy of the hypermolecular vertices (as in classical MTD), but also by additional descriptors for each vertex: fragmental van der Waals volumes, fragmental hydrophobicities, partial atomic charges, etc. This method was applied to a series of 73 polyhalogenated derivatives of dibenzo-p-dioxine, dibenzofuran and biphenyl (induction of aryl hydrocarbon hydrolase and affinities to rat cytosolic receptor), previously studied by MTD. The separation of steric, hydrophobic, and electrostatic effects was achieved retranslating from the latent variable space into a linear combination of the initial structural variables. The MTD-PLS method yields more detailed results compared to classical MTD, indicating the importance of electrostatic effects at some substituent positions.

Abstract
A1 selective agonist and antagonist radioligands bind to the same A1 adenosine receptor binding subunit, as documented by photoaffinity labelling and partial peptide maps. In this study we document that although these radioligands recognize the same A1 adenosine receptor (A1AR), they recognize different numbers of A1ARs in bovine brain membranes, with agonist number being greater than antagonist number. Neither addition of guanine nucleotides nor removal of Mg2+ ions enhanced antagonist binding in membranes. On solubilization, agonists still recognized a greater number of A1ARs but addition of guanine nucleotides or removal of Mg2+ substantially increased the number of receptors detected with antagonist radioligands. The effects of Mg2+ and guanine nucleotides were not additive, suggesting that formation of a "low agonist-receptor-G protein state" by either modulating agent was sufficient to alter the receptor conformation such that it could be recognized by antagonist. These studies suggest that a proportion of the "precoupled A1AR-G protein complex" in membranes are in a conformation that cannot be recognized by antagonists and that membrane constraints are such that ions or guanine nucleotides cannot sufficiently modulate the conformation to allow it to recognize antagonists. On removal of membrane structure by solubilization, these constraints are removed.

Abstract
In 4 cases of heterochromic cyclitis with cataract, 5 cases of herpetic iridocyclitis, and 5 cases of senile cataract, hypersensitivity to both alpha-crystalline and uveal pigment was investigated by lymphocyte-transformation and leukocyte-migration tests. In 3 cases of heterochromic cyclitis with cataracts, cellular hypersensitivity to alpha-crystalline was proven. Basing on these findings, the role of hypersensitivity to lens proteins in the etiology of heterochromic cyclitis is suggested.
