Of all the methods of studying cranial blood circulation, which I will not list here, the best is the one in which the state of cranial blood circulation is judged by the blood pressure in the two ends of the carotid artery. Hrthle was the first to observe this method, and therefore the method itself is often called the Hrthle method. However, as Hrthle himself says, the idea of ​​a method existed before. So, A. Dastre and J. Morat, for the purpose of proving the existence of vasomotor fibers for the lower limb in n. ischiadicus, determined the blood pressure in the central end of one a. cruralis and in the peripheral end the other; on the side last n. ischiadicus overcame. With irritation of a peripheral nerve cut, the pressure increased in the peripheral end of the а. cruralis, remaining unchanged in the central cut. This increase in pressure in the operated limb, which coincides with the unchanged pressure in the rest of the body, proves that (with the indicated irritation) there is a reduction in small arteries.

Diseases that cause anemia are very diverse, and therefore it is very difficult to classify anemias according to their etiology, and due to various constitutional and other characteristics of the organism, the same cause can cause different phenomena. It is easier to approach the question of the cause of anemia by determining whether erythropoiesis suffers from this disease or whether there is an increased breakdown of red blood cells. In the body, the state of the blood is composed of two processes: on the one hand, erythropoiesis, on the other hand, the decay of erythrocytes. Demonstrative formula Yerringer'a E R D (Blutmauserung), where E is the number of erythrocytes, P is their production and D ~ destruction. As long as P balances M, the difference E. remains unchanged. If D, that is, hemolysis, increases more than P, then we get a hemolytic type of anemia. If D hemolysis remains unchanged, but P decreases we get an aplastic type of anemia.

The aim is to analyse how the British, radical avant-garde collective King Mob (KM) and the American Up Against the Wall Motherfucker (UAWMF) developed an idea of the body rooted in the Gothic and Romantic imagery of the monster and the mob that emphasised the revolutionary potential of ugliness. The body bridged aesthetics and politics, co-extensive with organisational principles that confronted society at large. On the one hand, KM viewed the ugliness of the mob as a physical force whose imagery was strong enough to destabilise the State, while on the other, UAWMF understood the hostility of society towards the body of the hippie as the locus point of a new identity and discourse for it.

The article constitutes an attempt at analysing futurist pronatalist discourse, on the basis of the manifestos and artistic praxis of the Futurists. The reproduction postulates, prevalent in the works of the Polish Futurists and usually placed in the context of vitalism, characteristic of the 1920s, are shown from a biopolitical perspective, emphasizing the intersection of the biological with the political and social horizons. The author attempts to trace especially the political entanglements of the “population project” of the Polish Futurists, which turns out be marked by numerous paradoxes, situating itself between the pronatalist rhetoric typical of nationalistdiscourse (on the one hand, the discourse promoted by F.T. Marinetti, and on the other, the one formulated in Poland directly after regaining independence) and thinking in terms of a community which starts from the material functions of the body. In this second context, the reproduction postulates are not only an attack on bourgeois morality, but are closely connected with the futurist critique of all social institutions and the state apparatus with its biopolitical dispositions.

Introduction. There is a lack of knowledge of the pathophysiological mechanisms that form peripheral nerve disorders in mercury lesions of professional origin. The study aims to reveal the mechanisms underlying peripheral nerve damage in the long-term post-contact period of chronic mercury intoxication (CMI). Materials and methods. Fifty-one people had the diagnosis of a long-term period of CMI. The post-contact period was 8.5±2.6 years. The authors compared the results with a control group of 26 healthy men who had no contact with toxic substances. Stimulating electroneuromyography was performed. We studied the body systems that could contribute to the formation of disorders in the peripheral nerves. Changes in peripheral hemodynamics were studied using reovasography. The content of autoantibodies, neuron-specific enolase, serotonin, histamine, catecholamines (epinephrine, dopamine), metanephrine, and neurotrophin-3 was reviewed. The content of ceruloplasmin, secondary products of lipid peroxidation processes, reduced glutathione, the activity of superoxide dismutase and the content of nitric oxide levels were determined. Results. The study established pathogenetic structural links of peripheral nerve disorders. The autoimmune process's role was to increase the range of antibodies to the MAG protein and increase the level of antibodies to DNA. Violations of elastic-tonic properties of peripheral vessels could be associated with the functional state of motor axons. The increased content of neurotransmitters is related to the state of peripheral blood circulation; the most pronounced changes were on the legs, which could contribute to the occurrence and maintenance of vasoconstriction. The role of oxidative stress in the formation of demyelinating disorders in patients' peripheral nerves in the long-term period of CRI is possible. Conclusion. Neuroimmunological processes has an essential role in the development of peripheral nerve demyelination was shown, which consists in an increase in the content of antibodies to the MAG protein expressed on Schwann cells of peripheral nerves and in an increase in the level of antibodies to DNA involved in the formation of demyelinating changes when exposed to metallic mercury. The revealed pathological changes in the state of the peripheral blood circulation, characterized by a violation of the vessels' elastic-tonic properties, leading to demyelination of motor axons in patients in the long-term period of CMI. The increased content of neurotransmitters in the examined is of great importance in the state of peripheral circulation. Pronounced changes in blood circulation are established on the lower extremities, which may be associated with the predominance of α-adrenergic receptors in the arterial bed and may contribute to the occurrence and maintenance of vasoconstriction in the legs. The relationship between changes in indicators of oxidative stress, consisting of a decrease in the value of superoxide dismutase and reduced glutathione, and the formation of demyelinating disorders of peripheral nerves in patients in the long-term period of CMI has been proved.

In the introduction to his great work of 2005, Framing the Early Middle Ages, Chris Wickham urged not only the necessity of carefully framing our studies at the outset but also the importance of closely defining the words and concepts that we employ, the avoidance ‘cultural sollipsism’ wherever possible and the need to pay particular attention to continuities and discontinuities. Chris has, of course, followed these precepts on a vast scale. My aim in this chapter is a modest one. I aim to review the framing of thirteenth-century England in terms of two only of Chris’s themes: the aristocracy and the state—and even then primarily in terms of the relationship between the two. By the thirteenth century I mean a long thirteenth century stretching from the period of the Angevin reforms of the later twelfth century on the one hand to the early to mid-fourteenth on the other; the reasons for taking this span will, I hope, become clearer during the course of the chapter, but few would doubt that it has a validity.

This paper will focus on one element of the pushback against the massive influx of immigrants taken in for humanitarian purposes, namely, an identity-based chauvinism which uses identity as the point of resistance to the perceived dilution of that identity, brought about by the transformation of culture induced by the incorporation of a foreign other. The solution to this perceived dilution is a simultaneous defence of that culture and a demand for a conformity to it. While those in the critical tradition have encouraged a counter-position of revolutionary transformation by the other through ethics, dialogue, or the multitude, such a transformation is arguably impeded by what is ultimately a repetition of the metaphysics of conformity. Drawing on the personalism of Emmanuel Mounier and the Eucharistic theology of Creston Davis and Aaron Riches, this paper submits an alternative identity politics position that completes the revolutionary impulse. Identity here is not the flashpoint of a self-serving conflict, but the launch-point of politics of self-emptying, whose hallmarks include, on the one hand, a never-ending reception of transformation by the other, and on the other hand, an anchoring in the Body of Christ that is at once ever-changing and never-changing.

The consideration of this problem is important for at least two reasons. In many countries there are reports of an increasing decline in public morals and of growing dishonesty and corruption in the life of the body politic. This is taking place at a time when the established religious systems are being subjected to the pressure of pseudo-scientific secularism on the one hand and the claims of modern alternative faiths on the other. Clearly the two developments are interconnected. Yet, to judge from the burden of many public utterances of responsible leaders, including the now important and significant ‘Moral Re-armament’ Group, the close dependence of moral truth and the truth about the character of reality is not realised. Most people are content to mutter the usual platitudes—‘Honesty is the best policy’, ‘Do please try to be good and speak the truth’. But the problem of truth is more complicated than our naīve moralists would have us believe.

Geographers are now taking the problematic of corporeality seriously. ‘The body’ is becoming a preoccupation in the geographical literature, and is a central figure around which to base political demands, social analyses, and theoretical investigations. In this paper I describe some of the trajectories through which the body has been installed in academia and claim that this installation has necessitated the uptake of certain theoretical legacies and the disavowal or forgetting of others. In particular, I trace two related developments. First, I point to the sometimes haphazard agglomeration of disparate theoretical interventions that lie under the name of postmodernism and observe how this has led to the foregrounding of bodily tropes of fragmentation, fluidity, and ‘the cyborg‘. Second, I examine the treatment of the body as a conduit which enables political agency to be thought of in terms of transgression and resistance. I stage my argument by looking at how on the one hand Marxist and on the other queer theory have commonly conceived of the body, and propose that the legacies of materialist modes of analysis have much to offer current work focusing on how bodies are shaped by their encapsulation within the sphere of the social. I conclude by examining the presentation of corporeality that appears in the first volume of Marx's Capital. I do so to suggest that geographers working on questions of subjectivity could profit from thinking further about the relation between so-called ‘new’ and ‘fluid’ configurations of bodies, technologies, and subjectivities in the late 20th-century world, and the corporeal configurations of industrial capitalism lying behind and before them.

AbstractQuite a few recent ECJ judgments touch on various elements of territorial rule. Thereby, they raise the profile of the main question this Article asks: Which territorial claims does the EU make? To provide an answer, the present Article discusses and categorizes the individual elements of territoriality in the EU’s architecture. The influence of EU law on national territorial rule on the one hand and the emergence of territorial governance elements at the European level on the other provide the main pillars of the inquiry. Once combined, these features not only help to improve our understanding of the EU’s distinctly supranational conception of territoriality. What is more, the discussion raises several important legitimacy questions. As a consequence, the Article calls for the development of a theoretical model to evaluate and justify territoriality in a political community beyond the state.

Abstract The art of bodypainting that is fairly unknown to a wider public turns the body into a canvas - it is a frequently used phrase in the field of bodypainting that illustrates the challenge it faces: it uses a three-dimensional surface and has to cope with its irregularities, but also with the model’s abilities and characteristics. This paper looks at individuals who are turned into art by bodypainting. Although body painting can be very challenging for them - they have to expose their bodies and to stand still for a long time while getting transformed - models report that they enjoy both the process and the result, even if they are not confident about their own bodies. Among the reasons there are physical aspects like the sensual enjoyment, but also the feeling of being part of something artistic. This is enhanced and preserved through double staging - becoming a threedimentional work of art and then being staged for photography or film clips. This process gives the model the chance to experience their own body in a detached way. On the one hand, bodypainting closely relates to the body and on the other hand, it can help to over-come the body.
