Since the first demonstration of a tissue and organ transilluminator by a graduate of the Kyiv University V.A. Milliot at the 1867 exhibition in Paris, many enthusiasts have dealt with this diagnostic method. This paper provides an overview of publications from the funds of the Kharkiv Medical Library, materials from the Internet about the “transillumination” method, about Moshe Zelmanovich Sigal, educated at Donetsk Medical Institute, his life path, predecessors and followers. Studies in transmitted light are based on the differences in the absorption of light by various structures of the body. Transillumination attracts with the possibility of its use during operations. Depending on the relative position of the light source, the object being studied, and the researcher, three types of transillumination are possible: 1) intracavitary — the light source is inserted into the organ cavity; 2) transorgan — the light source is located behind the organ; and 3) extracavitary — transillumination is performed from the outside into the hollow organ when the imaging is made using an optical device inserted into the organ cavity. Inflation of a cavity increases the transparency of its walls and allows identifying subtler structures of the body. Based on transillumination angioscopy, M.Z. Sigal a half century ago developed a technique for lifetime monitoring of blood flow through the intramural vessels of the walls of hollow organs. Due to the difference in the color of blood in the vessels, the veins produce more intense shadow images than the arteries during transillumination. Transillumination angioscopy is possible without contrast agents. The development of technical means, the emergence of new light sources and its transportation allow modern surgeons to guide the course of the operation until the last suture using transillumination.

Primary Focus

A review of Jelena Novak’s work is an excellent sphere within which to grapple with the term “postopera”, which was introduced into operatic theory by way of analogy with Hans-Thies Lehmann’s term “postdramatic theatre”. In addition to defining the characteristics of postopera, the work (and this review) offers a window into the history of opera and the development of the genre. Options for the interpretation of operatic works are presented mostly through the body-voice gap, that is, the difference between the visual and audible elements of operatic art; this relationship is redefined or, rather, foregrounded by postopera. The review highlights the author’s primary focus on six examples of postopera, for the most part postmodern and minimalist; discloses the broad theoretical and historical foundations, as well as methodologies, on which the author bases her discourse; and locates the book contextually in the wider theory of musical-theatre praxes. Additionally, it presents the meaning that Novak’s book could have in the Slovenian operatic space, identifies certain limitations of the work, and at the same time offers options for the broadening of the author’s questions and further research.

Effect Of Light

Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. The sizes of particles, bubbles or droplets can be determined by the Image Analysis Technique. It is known that the quality of captured images depends significantly on the original image background that is mainly affected by the type of the light source. The aim of this contribution is to investigate the effect of light source type on image quality. The four types of light sources were tested: 1) 1000 W halogen lamp, 2) 72 W LED bar panel, 3) 60 W LED chip, and 4) 90 W LED chip. The illumination intensity and image background quality were investigated for each tested light sources. The effect of the shutter speed on evaluated particle sizes was tested using monodisperse spherical calibration particles having diameter of 1.19 mm. The difference observed between particle sizes evaluated by image analysis for given light source and declared calibration particle diameter was used as a measure of light source quality.

Physical Findings

Background: A rarity of form of vasculitis, also known as TAK, induces inflammation in the walls of the major arteries in the body: the aorta and its main branches. The disease results from a body attack and inflammation of the walls of the arteries caused by the body's own immune system. Case Presentation: A 37-years-old women had complaints of fever, giddiness, weakness of right upper limb and lower limb since1 day. After undergoing whole blood count, liver function examination, renal and MRI function checks, CT scan, angiography, etc. was studied. She was diagnosed with takayasu arteritis.  She had past medical history of neck pain and numbness since January 2020. For these complaints her family members referred her in private hospital. There is no significant history of surgery in present, lower segment caesarean section and piles operation was done previously. Physical findings were normal except the Glasgow Coma Scale score was 11 that is, patient  was semi-conscious, In General appearance patient activity was dull and weak due disease condition, Patient’s all routine investigations were normal except few like Total WBC count was increased (21,500cell /cm) due to increased infection, Granulocytes were increased  that is 75 % due to infection and autoimmune disease, ESR was increased  that is52mm/h. Angiography showed block in the right common carotid artery, MRI- showed Acute infract in left fronto  temporo parietal region involving insular par ventricular white matter,  absent flow in distal M1 segment of MCA. Conclusion: The most frequently involved arteries and the angiographic trends in this Takayasu Arteritis study were subclavian arteries and carotid arteries. The difference between angiographic characteristics may lead to clinical differences. Operations and surgery should be carried out at various points in the course of the disease.

The Difference

We tested the hypothesis that the phototatic response of nocturnal insects is influenced by the flickering of light sources by comparing the numbers of insects captured in traps illuminated with flickering and non-flickering light. Four flicker profiles produced by a square pulse wave with different combinations of frequency and duty cycle were investigated. Overall, fewer insects were captured in traps illuminated with a flickering light source, independent of the flicker setting used. Furthermore, the difference observed was statistically significant for specific combinations of flickering conditions and insect orders, thus suggesting that flickering reduces the number of nocturnal insects attracted to light sources.

Relevance. Movement surrounds and accompanies us everywhere: planets move, time, river waters, the life of cities is accompanied by traffic along highways. Our own life is also inseparable from the phenomenon of movement, both at the micro and macro levels: whether it be the movement and division of atoms of matter and cells of the body, the movement and interaction of our bodies in space, or the movement of a person towards a specific goal, conditioned by intention and expressed in actions, which in themselves are also a movement of the will. Purpose: to describe and evaluate the nature of the phenomenon of movement both in the history of philosophy (from Zeno to Descartes and Bergson) and in the history of medicine (from Aristotle and Celsus to modern mechanisms that give a person a chance to return the possibility of movement as an aspect of full life). Methods: the research method is not only the analysis of the development of the phenomenon of movement in the history of philosophy and science, but also the analysis of the influence of modern technologies on the very understanding of the nature of movement not as a physiological, but as an ontological phenomenon. Results. The ancient idea of movement as a deception of the senses, describing the closed on itself the existence of an objectively motionless space or being the source and cause of eternally arising and disintegrating existence, was an attempt by thinkers to “catch the mind on being”, not just creating a picture of a single cosmos, but also comprehending him as part of the human world. The bodily movement and structure of a person was understood as part of the visible and speculative structure of being. The thought of the Middle Ages, which understood movement as the path of the world and man to God, perceived the phenomenon of movement as an expression of free will and, at the same time, the desire of the world to its completion, which is at the same time the moment of its transformation. The Renaissance epoch, which proclaimed man as an end in itself for existence, closely links the physical movement of man with the movement of the cosmos, and considers the visible nature to be the source of knowledge of the Divine Will. The New Time, which theoretically separated the mechanics of the bodily and the impulses of the soul and mind and declared man a “biological machine”, in fact does not break the relationship between the movement of the soul and the body, but, demonstrating the difference in the nature of these movements, anticipated the discovery of psychosomatics. Finally, modern times not only created a classification of “body techniques” inherent in various stages of human life and groups of people, describing the socio-cultural aspect of corporeality, but also perceived movement as an act of our existence and involvement in the existence of the world. Conclusion. Movement cannot be understood as a purely physiological act. In the process of growth, becoming, having barely learned to walk, we are faced with the need to perform actions, to “behave”, to be like a personal I and as a part of the moving world that collided with us. A world in which every step is an event and deed capable of defining “the landscape of our personal and universal being”.

A surprising omission in New Testament studies of the imperial world is a comparison of Augustus's conception of rule in theRes Gestae(RG) with Paul's eschatological gospel of grace in his letter to the Romans. Even though each document has been foundational in the history of Western civilization, a comparison of their vastly different social outcomes has not been undertaken. Neil Elliott has made an outstanding contribution in laying the foundations for such a study, offering a scintillating analysis of Paul's letter to the Romans in terms ofiustitia(justice),clementia(mercy),pietas(piety), andvirtus(valor), the four virtues of Augustus inscribed on the Golden Shield erected in the Julian senate house (RG34.2). However, a full-scale investigation of the Augustan conception of rule in theRGwould open up new perspectives on Paul's engagement with the imperial world in Romans, given that Augustus became the iconicexemplumof virtue for his Julio-Claudian successors. Nonetheless, the difference in genre and aims of each document makes such a comparison daunting for New Testament scholars, as does the controversy that each document continues to generate in its own discipline. Further, we are unsure about the extent of the exposure that Paul might have had to theRG, directly or indirectly. Possibly Paul saw a Greek version of theRGtext at Pisidian Antioch, along with the Latin text that still survives there, during his first missionary journey (Acts 13:14–50), even though there are no archaeological remains of the Greek text at Antioch today. Presumably Paul would have been aware that the original Latin copy of theRGwas inscribed in bronze at Augustus's mausoleum at Rome. This article will argue that Paul, in planning to move his missionary outreach from the Greek East to the Latin West (Rom 15:19a–24), thought strategically about how he was going to communicate the reign of the crucified, risen, and ascended Son of God to inhabitants of the capital who had lived through the “Golden Age” of grace under Augustus and who were experiencing its renewal under Nero. What social and theological vision did Paul want to communicate to the city of Rome in which Augustus was the yardstick of virtue to which future leaders of Rome should aspire?

Compare the different appearance of jadeite-jade with three standard light sources, daylight D65,incandescent light A and fluorescent light F2(CWF),whose colors are purple to bluish violet with low chroma and low lightness in. The analysis of color index in the CIE 1976L* a* b uniform color space shows that the hue of lavender is influence by the light of standard light sources, followed by chroma, simultaneously value is seldom influenced obviously. And the color saturation of purple jade samples with CWF is usually higher, showing more vivid purple. However, D65 is benefit to the lightness of the purple jade, in which the average of color differences is known as the largest while the variance is the smallest. As D65 can be used to distinguish the purple color of jade samples most greatly, it is intended to be the best light source for appreciation of jadeite-jade. In consideration of the better quality of the purple color displayed with the CWF, it can be used during business transaction process.

Background and Importance: Spondylodiscitis is an inflammatory disease of the body of one or more vertebrae and intervertebral disc. The fungal etiology of this disease is rare, particularly in patients without immunodeficiency. Delay in diagnosis and treatment of this disease can lead to complications and even death. Case Presentation: A 63-year-old diabetic female patient, who had a history of spinal surgery and complaining radicular lumbar pain in both lower limbs with a probable diagnosis of spondylodiscitis, underwent partial L2 and complete L3 and L4 corpectomy and fusion. As a result of pathology from tissue biopsy specimen, Aspergillus fungi were observed. There was no evidence of immunodeficiency in the patient. The patient was treated with Itraconazole 100 mg twice a day for two months. Pain, neurological symptom, and laboratory tests improved. Conclusion: The debridement surgery coupled with antifungal drugs can lead to the best therapeutic results.
