The article is devoted to the study of an urgent problem of modern humanity – the fight against a pandemic caused by a new coronavirus infection, namely: the study of the mechanism of development of ‘long Covid’ (post-covid syndrome), a new clinical and laboratory method of its diagnosis, issues of drug and non-drug rehabilitation of patients who have suffered COVID‑19. The paper describes the etiopathogenesis of post-covid syndrome (PS), the distinctive features of which are the defeat of the cardiovascular, respiratory, nervous, digestive, immune systems of the body, ENT organs and musculoskeletal system. For the diagnosis of post-covid syndrome, a monochrome nanoparticle analyzer (MAN) has been tested for the first time in the Russian Federation, which allows determining pathophysiological shifts in the homeostasis system. It was found that the MAN method has a sufficiently high diagnostic sensitivity (78%), and shifts in the homeostasis system in post-covid syndrome are statistically significant (p < 0.001). A fundamentally important point of this study is that an algorithm has been developed for noninvasive diagnosis of PS by saliva (oropharyngeal flushes), based on the detection of a high contribution to the scattering of laser radiation in the mid-frequency range of the spectrum on nanoparticles ranging in size from 119 to 121 nm. The article also pays special attention to medicinal and non-medicinal methods of treatment of patients with ‘long Covid’ experiencing the consequences of a new coronavirus infection. It has been established that the best effect is provided by complex treatment combining methods of the traditional European school (drug therapy with the use of cardiovascular drugs, nootropic agents, chondroprotectors, vitamins and mineral complexes, hormones, hepatoprotectors, biostimulants, sedatives and anti-inflammatory drugs and other drugs) and non-drug methods of restorative treatment practiced by Oriental medicine (acupuncture, hirudotherapy, massage, osteopathy, etc.).

Despite the height of the coronavirus infection, the Nobel Prize in Medicine was awarded in Stockholm in October 2020. This event was held online for the first time and was not accompanied by the traditional honoring of the laureates. In his will, Alfred Nobel entrusted the selection of the winner in this nomination to the Karolinska Medical and Surgical University of Stockholm, and the first award in this nomination took place in 1901. Since then, this event has been held 110 times, and 216 scientists have become laureates of the prize in the field of physiology and medicine, since the nominees are often not just one, but a group of researchers. This happened in 2020 - for research in the field of studying the hepatitis C virus, three scientists received the most prestigious award: the British Michael Houghton and the Americans Harvey Alter and Charles Rice. Due to the results of the research, which these three people conducted separately from each other, for the first time it became possible to completely eliminate the virus from the body.

Introduction. The article is devoted to the study of the mechanism of occurrence of postcovid syndrome, a new laboratory method for its diagnosis and issues of drug and non-drug rehabilitation of patients who have suffered COVID-19.The purpose of this work was to study the possibilities of using the method of monochrome analysis of nanoparticles for instrumental and laboratory diagnostics of postcovid syndrome and to substantiate the use of complex therapeutic approaches to the treatment of patients.Materials and methods. The biomaterial (saliva) of 250 patients who underwent COVID-19 in mild, moderate and severe forms, with a slight predominance of males, in the age range from 18 to 75 years, who were in the Center of Eastern and European Medicine (Moscow) on rehabilitation treatment in the period from June 2020 to September 2021, was studied by the method of monochrome analysis of nanoparticles. According to the results of the work carried out, it was found that the most typical saliva spectrum of patients diagnosed with “postcovid syndrome” was multimodal (three or more peaks) with the greatest contribution (45%) to light scattering on agglomerates of  nanoparticles with a  diameter of  more than 1000  nm, with detectable nanoparticles of the middle sub-range of the spectrum from 119 to 122 nm with a 15% contribution to light scattering and an increased contribution to light scattering up to 41% on small nanoparticles with a diameter of 22 nm.Results. Analysis of the results of the study showed a statistically significant (p < 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group). Conclusions. An algorithm for non-invasive diagnosis of postcovid syndrome by saliva was developed. Also, special attention was paid during the study to the development of an integrated approach to the rehabilitation of patients who have undergone a new coronavirus infection, including medicinal and non-medicinal methods of treatment. >< 0.01) appearance of a peak of 119 nm on the histogram of patients, which was not observed either in the group of practically healthy individuals (control group) or in the group of patients with general somatic pathology (comparison group).Conclusions.

Methods Of Treatment

Therapeutic nihilism was at its peak in the late nineteenth century. An excellent example of a drugless therapeutic procedure is that described almost 80 years ago by Dr. H. V. Knaggs. The interest that often attaches itself to simple methods of treatment must be my excuse for resuscitating an old but, at the same time, very little known remedy for preventing the recurrence of ordinary sore throats. Most people, when they hear of it for the first time, are very apt to smile incredulously, and to at once put it down among the category of superstitions, "old women's remedies," etc. In fact, nearly every patient to whom I have suggested it has appeared sceptical of its utility at first, although subsequently a careful trial has frequently convinced them to the contrary. Its prophylactic powers are undoubted. The treatment alluded to consists merely in placing round the neck from ten to twenty threads of Berlin wool. This must be worn continuously night and day, and not taken off except for the purpose of making ablutions. With some cases it is necessary that the wool should be worn all the year round; with others, during the months when the complaint is likely to return. When it is thought desirable to discontinue its use, it should be done gradually by discarding a single thread each day until none are left. If objected to on the score of unsightliness, a small coin or locket may be attached, which will effectually keep the wool out of sight, and, after a time, out of mind. Laryngitic and tonsillitic forms for disease, which are especially prevalent among children, are due in very many instances to exposure and cold, and are particularly apt to recur periodically, especially in the colder and more changeable periods of the year. It is in such cases that the treatment is productive of marked benefit. A considerable number of cases, both among children and adults, have been thus treated in our practice. Observations as to its efficacy have extended over a number of years. Strange as it may seem, scarcely in any single instance has it failed in our hands to avert future attacks. The question naturally arises, How can a simple remedy like a few threads of wool possibly effect this object? or in what manner does it act? In the first place, we know that wool is a bad conductor of heat. Secondly, according to the principles laid down by Dr. Jaeger in his system of sanitary clothing, ventilation is one of the best means at our disposal for promoting skin action, and for retaining the body at an equable temperature both in summer and winter. It is probable, therefore, that the skein of wool, when attached round the neck, keeps up a belt of skin-action, and so acts continuously, and in a slight degree, as a mild counter-irritant.

Ibuprofen is a long lasting non-steroidal anti-inflammatory drugs (NSAIDs) and still represents one of the most diffused analgesics around the world. It has an interesting story started over 50 years ago. In this short comment to an already published paper, the authors try to focus some specific important point. On top, they illustrate the recent, confusing and fake assertion on the potentially dangerous influence that ibuprofen could have, increasing the risk of Coronavirus infection. This is also better illustrated in a previously published paper, where the readers could find more clear responses to eventual doubts.

Biopotential Recording

AbstractContinuous multi-channel monitoring of biopotential signals is vital in understanding the body as a whole, facilitating accurate models and predictions in neural research. The current state of the art in wireless technologies for untethered biopotential recordings rely on radiative electromagnetic (EM) fields. In such transmissions, only a small fraction of this energy is received since the EM fields are widely radiated resulting in lossy inefficient systems. Using the body as a communication medium (similar to a ’wire’) allows for the containment of the energy within the body, yielding order(s) of magnitude lower energy than radiative EM communication. In this work, we introduce Animal Body Communication (ABC), which utilizes the concept of using the body as a medium into the domain of untethered animal biopotential recording. This work, for the first time, develops the theory and models for animal body communication circuitry and channel loss. Using this theoretical model, a sub-inch$$^3$$ 3 [1″ × 1″ × 0.4″], custom-designed sensor node is built using off the shelf components which is capable of sensing and transmitting biopotential signals, through the body of the rat at significantly lower powers compared to traditional wireless transmissions. In-vivo experimental analysis proves that ABC successfully transmits acquired electrocardiogram (EKG) signals through the body with correlation $$>99\%$$ > 99 % when compared to traditional wireless communication modalities, with a 50$$\times$$ × reduction in power consumption.

AbstractMusic has been steadily rising up the historical agenda, a product of the emergence of sound studies, the history of the senses, and a mood of interdisciplinary curiosity. This introductory article offers a critical review of how the relationship between music and politics has featured in extant historical writing, from classic works of political history to the most recent scholarship. It begins by evaluating different approaches that historians have taken to music, summarizes the important shifts in method that have recently taken place, and advocates for a performance-centered, contextualized framework that is attentive to the distinctive features of music as a medium. The second half examines avenues for future research into the historical connections between music and politics, focusing on four thematic areas—the body, emotions, space, and memory—and closes with some overarching reflections on music's use as a tool of power, as well as a challenge to it. Although for reasons of cohesion, this short article focuses primarily on scholarship on Britain and Ireland in the eighteenth and nineteenth centuries, its discussion of theory and methods is intended to be applicable to the study of music and political culture across a broad range of periods and geographies.

Interspecies Barrier

COVID-19 is a highly contagious new infection caused by the single-stranded RNA Sars-CoV-2 virus. For the first time, this infection was recorded in December 2019 in the Chinese province of Wuhan. The virus presumably crossed the interspecies barrier and passed to humans from a bat. Initially, the disease was considered exclusively in the context of damage to the respiratory system, but it quickly became clear that the disease also entails serious consequences from various systems, including the cardiovascular system. Among these consequences are myocarditis, myocardial damage, subsequent heart failure, myocardial infarction, and Takotsubo syndrome. On the other hand, clinical data indicate that the presence of chronic diseases in a patient aggravates the course and outcome of coronavirus infection. In this context, the relationship between COVID-19 and atherosclerosis, a condition preceding cardiovascular disease and other disorders of the heart and blood vessels, is particularly interesting. The renin-angiotensin system is essential for the pathogenesis of both coronavirus disease and atherosclerosis. In particular, it has been shown that ACE2, an angiotensin-converting enzyme 2, plays a key role in Sars-CoV-2 infection due to its receptor activity. It is noteworthy that this enzyme is important for the normal functioning of the cardiovascular system. Disruptions in its production and functioning can lead to various disorders, including atherosclerosis.

AbstractBody ownership concerns what it is like to feel a body part or a full body as mine, and has become a prominent area of study. We propose that there is a closely related type of bodily self-consciousness largely neglected by researchers—experiential ownership. It refers to the sense that I am the one who is having a conscious experience. Are body ownership and experiential ownership actually the same phenomenon or are they genuinely different? In our experiments, the participant watched a rubber hand or someone else’s body from the first-person perspective and was touched either synchronously or asynchronously. The main findings: (1) The sense of body ownership was hindered in the asynchronous conditions of both the body-part and the full-body experiments. However, a strong sense of experiential ownership was observed in those conditions. (2) We found the opposite when the participants’ responses were measured after tactile stimulations had ceased for 5 s. In the synchronous conditions of another set of body-part and full-body experiments, only experiential ownership was blocked but not body ownership. These results demonstrate for the first time the double dissociation between body ownership and experiential ownership. Experiential ownership is indeed a distinct type of bodily self-consciousness.

Abstract This study explores the representation and use of Victorian visual aids, specifically focusing on how the design of spectacle and eyeglass frames shaped ideas of the ‘normal’ and ‘abnormal’ body. It contributes to our understanding of assistive technologies in the Victorian period by showcasing the usefulness of material evidence for exploring how an object was produced and perceived. By placing visual aids in their medical and cultural context for the first time, it will show how the study of spectacle and eyeglass frames develops our understanding of Victorian society more broadly. Contemporaries drew upon industrialization, increasing education, and the proliferation of print to explain a rise in refractive vision ‘errors’. Through exploring the design of three spectacle frames from the London Science Museum’s collections, this study will show how the representations and manufacture of visual aids transformed in response to these wider changes. The material evidence, as well as contemporary newspapers, periodicals, and medical texts, reveal that visual aids evolved from an unusual to a more mainstream device. It argues that visual aids are a unique assistive technology, one that is able to inform our understanding of how Victorians measured the body and constructed ideas of ‘normalcy’ and ‘abnormalcy’.
