Introduction. The interest in Nikola Tesla, a scientist, physicist, engineer and inventor, is constantly growing. In the millennia-long history of human civilization, it is almost impossible to find another person whose life and work has been under so much scrutiny of such a wide range of researchers, medical professionals included. Although Tesla was not primarily dedicated to biomedical research, his work significantly contributed to the development of radiology, and high frequency electrotherapy. This paper deals with the impact of Tesla?s work on the development of a new medical branch - radiology. Nikola Tesla and the Discovery of X-ray radiation. Tesla pioneered the use of X-rays for medical purposes, practically laying the foundations of radiology. Namely, since 1887, Tesla periodically experimented with X-rays, at that time still unknown and unnamed, which he called "shadowgraphs". Moreover, at the end of 1894, he conducted extensive research focusing on X-rays, but unfortunately it was interrupted after the fire burning down his laboratory in 1895. In 1896 and 1897, Tesla published ten papers on the biologic effects of X-ray radiation. All his studies on X-rays were experimental. During 1896 and 1897, Tesla continued improving X-ray devices. Apart from this, Tesla was the first to point out the harmful effects of exposure to X-ray radiation on human body. Conclusion. Nikola Tesla was a visionary genius of the future. Tesla?s pioneer steps, made more than a century ago in the domain of radiology, are still being used today.

Nikola Tesla was an ingenious and briliant scintifist which contributed to the science and technology prosperity of the world. Nikola Tesla discovered high frequency oscillator 1891 year, and afterwards, single electrode X-ray tube without target electrode, electron (?particles charged with electricity?), Bremsstrahlung or ?breaking radiation? or ?very special radiation? (X-radiation) in 1892 year, biological hazards of X-rays, and more about 700 inventions, and 112 patents. Tesla's research work in the field of X-rays was stopped in 1895 because burned in his laboratory. When W. C. R?ntgen 1895, recognition X-rays, Tesla restored his work on this field and sent R?ntgen a telegram with congratilations and R?ntgen shows obtained with X-ray tubes which operated with high frequency currents. Tesla discovered many secret of nature.

To celebrate the fiftieth anniversary of the discovery of X-rays by William Conrad Rontgen, which was made on 8 November 1895, a series of meetings were held in London during November 1945, twelve Societies participating. The inaugural meeting was held under the auspices of the Royal Society at Burlington House on 8 November, and was opened by the reigning President, Sir Henry Dale. He referred to the early history of the discharge in vacuo and gave a lively account of the impact of the discovery on men of science at Cambridge, where he was an undergraduate at the time. The discussion, devoted to various aspects of Rontgen’s great discovery and to its influence, was opened by Sir Lawrence Bragg, who gave an account of the contents of the two chemical papers in which Rontgen announced his findings to the world, one dated December 1895 and the other March 1896. Sir Lawrence drew attention to the wide range of this pioneer work and also to an important early letter of Schuster’s on the rays, published in Nature on 23 January 1896, with a full translation of Rontgen’s first paper.

The Canadian Light Source (CLS) in Saskatoon has been under construction for the last 4 years, and will be producing a number of very intense beams of far-IR, IR, soft and hard X-rays in 2004 for use by several hundred Canadian scientists in chemistry, surface and material science, and a host of other scientific disciplines. The CLS will dramatically enhance the Canadian spectroscopic tradition that Gerhard Herzberg help create. I begin this article (from my 2002 CIC Montreal Medal lecture) with an overview of the history of SR in Canada, beginning in 1972 with the first Canadian synchrotron workshop organized at the University of Western Ontario by Bill McGowan, and attended by Dr. Herzberg. The CLS facility is then described, along with the properties of the first and second set of beamlines to be built at the CLS. These SR beams, in the IR and X-ray regions from the third generation CSL ring, will be competitive in brightness and intensity with the best beamlines in the world for most applications. Finally, some of the present Canadian SR research at foreign SR sources is described across the entire SR spectrum. All known spectroscopic and diffraction experiments are dramatically enhanced with SR; and SR opens up new areas of spectroscopy, microscopy, and spectromicroscopy that cannot be studied with any other source of radiation.Key words: synchrotron light, X-rays, infrared, spectroscopy.

Introduction. Shortly after the discovery of X-rays, their practical application in the clinical practice became the object of interest of many non-medical individuals. One of them was the famous Serbian writer, Branislav Nusic. This paper presents the life and work of Branislav Nusic, as well as his article: ?Roentgen?s Photography? which was published in the journal ?Politics? (July 8, 1906; N? 892, p. 3), under the alias Ben Akiba, in the Cyrillic script. The life and work of Branislav Nusic. Alchiviadi Nu?a, later Branislav Nusic (1864 - 1938) was a great Serbian literate, playwright, journalist, photographer, politician, diplomat, member of the Serbian Royal Academy, President of the Association of Yugoslav Playwrights, manager of the theaters in Belgrade, Novi Sad, Skopje and Sarajevo, and a military volunteer in the Serbian - Bulgarian war (1885). ?Roentgen?s Photography?. The author wrote this text in his own way, the only way he could and knew, vividly and wittily. He knew about the great power and strength of X-ray radiation, and he wrote of his knowledge in this short story. Without Branislav Nusic, the history of Serbian radiology would be poorer for not seeing the X-rays by the eyes of an educated, intelligent and, above all, humorous writer. Conclusion. Branislav Nusic, alongside Nikola Tesla, Mihajlo Pupin Idvorski, Dr. Abraham Vinaver, and all past and present Serbian radiologists, has become an essential and memorable link in the chain of the history of the Serbian radiology.

In Religion and Medicine, Dr. Jeff Levin, distinguished Baylor University epidemiologist, outlines the longstanding history of multifaceted interconnections between the institutions of religion and medicine. He traces the history of the encounter between these two institutions from antiquity through to the present day, highlighting a myriad of contemporary alliances between the faith-based and medical sectors. Religion and Medicine tells the story of: religious healers and religiously branded hospitals and healthcare institutions; pastoral professionals involved in medical missions, healthcare chaplaincy, and psychological counseling; congregational health promotion and disease prevention programs and global health initiatives; research studies on the impact of religious and spiritual beliefs and practices on physical and mental health, well-being, and healing; programs and centers for medical research and education within major universities and academic institutions; religiously informed bioethics and clinical decision-making; and faith-based health policy initiatives and advocacy for healthcare reform. Religion and Medicine is the first book to cover the full breadth of this subject. It documents religion-medicine alliances across religious traditions, throughout the world, and over the course of history. It summarizes a wide range of material of relevance to historians, medical professionals, pastors and theologians, bioethicists, scientists, public health educators, and policymakers. The product of decades of rigorous and focused research, Dr. Levin has produced the most comprehensive history of these developments and the finest introduction to this emerging field of scholarship.

The Impact

The potential utilization of wood/polyvinyl chloride (WPVC) composites containing an X-ray protective filler, namely bismuth oxide (Bi2O3) particles, was investigated as novel, safe, and environmentally friendly X-ray shielding materials. The wood and Bi2O3 contents used in this work varied from 20 to 40 parts per hundred parts of PVC by weight (pph) and from 0 to 25, 50, 75, and 100 pph, respectively. The study considered X-ray shielding, mechanical, density, water absorption, and morphological properties. The results showed that the overall X-ray shielding parameters, namely the linear attenuation coefficient (µ), mass attenuation coefficient (µm), and lead equivalent thickness (Pbeq), of the WPVC composites increased with increasing Bi2O3 contents but slightly decreased at higher wood contents (40 pph). Furthermore, comparative Pbeq values between the wood/PVC composites and similar commercial X-ray shielding boards indicated that the recommended Bi2O3 contents for the 20 pph (40 ph) wood/PVC composites were 35, 85, and 40 pph (40, 100, and 45 pph) for the attenuation of 60, 100, and 150-kV X-rays, respectively. In addition, the increased Bi2O3 contents in the WPVC composites enhanced the Izod impact strength, hardness (Shore D), and density, but reduced water absorption. On the other hand, the increased wood contents increased the impact strength, hardness (Shore D), and water absorption but lowered the density of the composites. The overall results suggested that the developed WPVC composites had great potential to be used as effective X-ray shielding materials with Bi2O3 acting as a suitable X-ray protective filler.

AbstractAs a radiation biodosimetry tool, gene expression profiling is being developed using mouse and human peripheral blood models. The impact of dose, dose-rate, and radiation quality has been studied with the goal of predicting radiological tissue injury. In this study, we determined the impact of aging on the gene expression profile of blood from mice exposed to radiation. Young (2 mo) and old (21 mo) male mice were irradiated with 4 Gy x-rays, total RNA was isolated from whole blood 24 h later, and subjected to whole genome microarray analysis. Pathway analysis of differentially expressed genes revealed young mice responded to x-ray exposure by significantly upregulating pathways involved in apoptosis and phagocytosis, a process that eliminates apoptotic cells and preserves tissue homeostasis. In contrast, the functional annotation of senescence was overrepresented among differentially expressed genes from irradiated old mice without enrichment of phagocytosis pathways. Pathways associated with hematologic malignancies were enriched in irradiated old mice compared with irradiated young mice. The fibroblast growth factor signaling pathway was underrepresented in older mice under basal conditions. Similarly, brain-related functions were underrepresented in unirradiated old mice. Thus, age-dependent gene expression differences should be considered when developing gene signatures for use in radiation biodosimetry.

The Relationship

The buzz about hyaluronan (HA) is real. Whether found in face cream to increase water volume loss and viscoelasticity or injected into the knee to restore the properties of synovial fluid, the impact of HA can be recognized in many disciplines from dermatology to orthopedics. HA is the most abundant polysaccharide of the extracellular matrix of connective tissues. HA can impact cell behavior in specific ways by binding cellular HA receptors, which can influence signals that facilitate cell survival, proliferation, adhesion, as well as migration. Characteristics of HA, such as its abundance in a variety of tissues and its responsiveness to chemical, mechanical and hormonal modifications, has made HA an attractive molecule for a wide range of applications. Despite being discovered over 80 years ago, its properties within the world of fascia have only recently received attention. Our fascial system penetrates and envelopes all organs, muscles, bones and nerve fibers, providing the body with a functional structure and an environment that enables all bodily systems to operate in an integrated manner. Recognized interactions between cells and their HA-rich extracellular microenvironment support the importance of studying the relationship between HA and the body’s fascial system. From fasciacytes to chronic pain, this review aims to highlight the connections between HA and fascial health.

The Impact

Every few decades, the world order changes due to various geopolitical, economic and other circumstances. For example, as a result of globalization, the world order has undergone significant changes in the last forty years. Globalization has led to the destruction of the postwar world order, as well as to world leadership by the United States and the West. However, in recent decades, as a result of globalization, the U.S. and the West began to cede their leadership to developing countries, so there is now a change in the economic structure of relations in the world system. Today the center of economic growth is in the East, namely in Asia. There are no new superpowers in the world at the moment, but the unipolar world will cease to exist due to the weakening of the U. S. leadership, which will lead to a change in the world order. A new leader, which may replace the U. S., will not have as wide range of advantages as the USA has. Most likely, the essence of the new order will be to unite the largest countries and alliances into blocks, for example, the USA together with the Trans-Pacific Partnership, the EU, etc. The article outlines forecasts of GDP growth rates as well as the global energy outlook; analyzes the LNG market as well as the impact of the pandemic on the global oil and gas market; and lists the characteristics of U. S. geopolitics.
