A brief informational material on the history of the use of phytoncides in medical practice over the past few centuries and the results of our own research on the study of the properties of new drugs based on phytoncides in liposomes is proposed. The effectiveness of phytoncides use for 20 years within the framework of the «Indoor Airspace Ecology» program indicates that this direction is promising. Key words: phytoncides, liposomes, antibacterial agents

Staphylococcus is considered to be one of the most common pathogens that can lead to the development of numerous pathological processes, from pyoderma to peritonitis. Being a potentially pathogenic microorganism, it is able not to make itself noticed for years, peacefully coexisting with the host organism. But should one only go through a viral infection out of bed, suffer from stressful situations, or simply get overcooled, the potentially pathogenic microflora activates and manifests itself as a local or general infectious process. Activation of staphylococcal microflora is most often observed in sickly people with weakened immune systems, suffering from endocrine diseases, having long ellneses. Long-term and uncontrolled use of antibiotics with the formation of resistance to them is also of great importance. It is the widespread distribution of antibiotic-resistant strains of staphylococcus that makes doctors and scientists look for new forms of controling this and other microorganisms. Against this background, it’s time to recall the bacteriophages long forgotten in the era of the craze for antibiotics, especially given the fact that over the past thirty years not a single completely new group of antibacterial agents has been synthesized.

AbstractInfluenza is an acute respiratory illness caused by the influenza A, B, and C viruses. It can occur in local outbreaks or seasonal epidemics, with possibility to spread worldwide in a pandemic when a novel strain with significant antigenic differences emerges. During the past years, several new drugs have become available, with different accessibility related to specific countries' approval. We have conducted a review of literature, analyzing the most recent data on efficacy and safety of drugs currently available to treat influenza, with a particular attention toward special populations. Efficacy and safety profile of neuraminidase inhibitors (oseltamivir, zanamivir, laninamivir, peramivir) and recently approved cap-dependent endonuclease inhibitor baloxavir marboxil are reported in literature, but still little information is available about special populations such as critically ill patients and patients with a history of chronic respiratory disease. Moreover, the emergence of strains with reduced or no susceptibility to current drugs is a matter of concern, suggesting the need of constant monitoring of viral variants.

It is generally accepted that history is an element of culture and the historian a member of society, thus, in Croce's aphorism, that the only true history is contemporary history. It follows from this that when there occur great changes in the contemporary scene, there must also be great changes in historiography, that the vision not merely of the present but also of the past must change.

It is perhaps one of the most important characteristics of the past decade in astronomy that the evolution of some major classes of astronomical objects has become accessible to detailed research. The theory of the evolution of individual stars has developed into a substantial body of quantitative investigations. The evolution of galaxies, particularly of our own, has clearly become a subject for serious research. Even the history of the solar system, this close-by intriguing puzzle, may soon make the transition from being a subject of speculation to being a subject of detailed study in view of the fast flow of new data obtained with new techniques, including space-craft.

Purpose The current “specific language impairment” and “developmental language disorder” discussion might lead to important changes in how we refer to children with language disorders of unknown origin. The field has seen other changes in terminology. This article reviews many of these changes. Method A literature review of previous clinical labels was conducted, and possible reasons for the changes in labels were identified. Results References to children with significant yet unexplained deficits in language ability have been part of the scientific literature since, at least, the early 1800s. Terms have changed from those with a neurological emphasis to those that do not imply a cause for the language disorder. Diagnostic criteria have become more explicit but have become, at certain points, too narrow to represent the wider range of children with language disorders of unknown origin. Conclusions The field was not well served by the many changes in terminology that have transpired in the past. A new label at this point must be accompanied by strong efforts to recruit its adoption by clinical speech-language pathologists and the general public.

Abstract. Background: Medical students are at high risk of suicidal ideation. Aim: We aimed to obtain information on suicidal ideation among medical students in Dammam located in the Eastern Province of Saudi Arabia. Method: This cross-sectional study was conducted at the College of Medicine affiliated with Imam Abdulrahman Bin Faisal University in the Eastern Province of Saudi Arabia. Suicidal ideation in the past 12 months was assessed based on responses to four questions in the depression subscale of the General Health Questionnaire 28 (GHQ-28). In addition, data were collected to examine the association of suicidal ideation with various factors. Results: We found that 1 in 3 medical students in the study had suicidal ideation in the past 12 months, while around 40% had lifetime suicidal ideation. Suicidal ideation was associated with feelings of parental neglect, history of physical abuse, and dissatisfaction with academic performance. Limitations: The cross-sectional nature of this study limits its ability to determine causality regarding suicidal ideation. Conclusion: These rates are considerably high when compared with rates from studies in other countries around the world. This study provides a reference in the field of suicidology for this region of Saudi Arabia.

The article is devoted to the study of inscriptions on the gravestones of Haji Ibrahim al-Uradi, his father, brothers and other relatives. The information revealed during the translation of these inscriptions allows one to date important events from the history of Highland Dagestan. Also we can reconsider the look at some important events from the past of Hidatl. Epitaphs are interesting in and of themselves, as historical and cultural monuments that needed to be studied and attributed. Research of epigraphy data monuments clarifies periodization medieval epitaphs mountain Dagestan using record templates and features of the Arabic script. We see the study of medieval epigraphy as one of the important tasks of contemporary Caucasian studies facing Dagestani researchers. Given the relatively weak illumination of the picture of events of that period in historical sources, comprehensive work in this direction can fill gaps in our knowledge of the medieval history of Dagestan. In addition, these epigraphs are of great importance for researchers of onomastics, linguistics, the history of culture and religion of Dagestan. The authors managed to clarify the date of death of Ibrahim-Haji al-Uradi, as well as his two sons. These data, the attraction of written sources and legends allowed the reconstruction of the events of the second half of the 18th century. For example, because of the epidemic of plague and the death of most of the population of Hidatl, this society noticeably weakened and could no longer maintain its influence on Akhvakh. The attraction of memorable records allowed us to specify the dates of the Ibrahim-Haji pilgrimage to Mecca and Medina, as well as the route through which he traveled to these cities.

The work aims to show a peculiar perspective of looking at photographs taken on the eve of the broadly understood disaster, which is specified in a slightly different way in each of the literary texts (Stefan Chwin’s autobiographical novel Krótka historia pewnego żartu [The brief history of a certain joke], a poem by Ryszard Kapuściński Na wystawie „Fotografia chłopów polskich do 1944 r.” [At an exhibition “The Polish peasants in photographs to 1944”] and Wisława Szymborska’s Fotografia z 11 września [Photograph from September 11]) – as death in a concentration camp, a general concept of the First World War or a terrorist attack. Upcoming tragic events – of which the photographed people are not yet aware – become for the subsequent recipient an inseparable element of reality contained in the frame. For the later observers, privileged with time perspective, the characters captured in the photograph are already victims of the catastrophe, which in reality was not yet recorded by the camera. It is a work about coexistence of the past and future in the field of photography.
