Rapid, sensitive, accurate and portable diagnostics are a mainstay of modern medicine. Tuberculosis is a disease that has been with us since time immemorial and, despite the fact that it can be treated and cured, it still remains the world's biggest infectious killer, taking the lives of millions annually. There have been important developments in the diagnostic devices for tuberculosis however, these are often prone to error, expensive, lack the necessary sensitivity or accuracy and, crucially, not sufficiently portable and thus not applicable in the remote, rural areas, where they are most needed. Modern solutions have been emerging in the past decade, seeking to overcome many of the inhibiting issues in this field by utilising recent advances in molecular biology, genetics and sequencing or even completely ‘reinventing the wheel’, by developing novel and unprecedented diagnostic techniques. In this mini review, the issues and challenges arising from the historical methods of diagnosing tuberculosis are discussed, followed by outlaying their particular lack of appropriateness for regions of the world where tuberculosis still remains endemic. Subsequently, more recent developments of new methods and technological advancements as ‘modern weapons’ in the battle to defeat this disease and associated challenges are reviewed, and finally an outlook is presented, highlighting the future of the modern solutions under development, which are envisioned to lay the platform for improvements in delivering timely intervention, reduce immense expense and burden on healthcare systems worldwide, while saving millions of lives and eventually, may enable the eradication of this ancient disease.

Every late spring since 1951, the Wiener Festwochen bring performers from around the world to Vienna for an opportunity to share recent developments in performance styles and present them to a Viennese public that seems to be increasingly open to experimentation. These festival weeks solidify a specific form of Viennese self-understanding and self-representation as a culture that is rooted in performance. This essay seeks to link two recent Austrian performances—one of them was part of the Wiener Festwochen in 2016, the other was staged in downtown Linz during the past few years—to this Austrian and specifically Viennese culture of performance by reading them as contemporary articulations of a tradition of radical performance art that can be traced back to the Viennese Actionism of the sixties and later feminist articulations in the seventies and eighties. They play on the dramatic effect of these actions, specifically their joy in cruelty, chaos, and orgiastic intoxication, by staging regressions and thus making visible what has been dammed up and repressed in contemporary society.1 Just as their historical models, these two performances merge the performing and the fine arts and they highlight provocative, controversial, and, at times, violent content. But they do it in an interspecies context that adds an entire layer of complexity to the project of societal and cultural critique.

The replacement of diseased organs and tissues by the healthy ones of others has been a unique milestone in modern medicine. For centuries, transplantation remained a theme of fantasy in literature and the arts. Within the past five decades, however, it has developed from a few isolated attempts to salvage occasional individuals with end-stage organ failure to a routine treatment for many patients. In parallel with the progressive improvements in clinical results has come an explosion in immunology, transplantation biology, immunogenetics, cell and molecular biology, pharmacology, and other relevant biosciences, with knowledge burgeoning at a rate not dreamed of by the original pioneers. Indeed, there have been few other instances in modern medicine in which so many scientific disciplines have contributed in concert toward understanding and treating such a complex clinical problem as the failure of vital organs. The field has been a dramatic example of evolution from an imagined process to an accepted form of therapy.

The number of dental radiographs taken in the UK has steadily increased over the past 20 years—recently estimating around 18 million taken in the general dental services alone, and dental radiographs now account for nearly 25% of all medical radiographic exposures.1 Radiographs remain our most useful diagnostic aid. Their strength is in demonstrating hard tissue pathology, which makes radiographs particularly effective in the maxillofacial region. Although well accepted in this capacity, there remain a number of limitations and drawbacks to conventional radiographs which recent developments have begun to overcome. There have been improvements in the scope and capabilities of dental imaging equipment. There has also been a continuing effort to reduce radiation-induced harm by limiting our exposure to it. This has been possible both through the introduction of new methods and protocols for reducing individual radiation exposures and by the creation of guidelines for selecting radiographs more effectively and thereby reducing the total number of radiographs taken.

Abstract There are different opinions around the World regarding the zoonotic capability of H3N8 equine influenza viruses. In this report, we have tried to summarize the findings of different research and review articles from Chinese, English, and Mongolian Scientific Literature reporting the evidence for equine influenza virus infections in human beings. Different search engines i.e. CNKI, PubMed, ProQuest, Chongqing Database, Mongol Med, and Web of Knowledge yielded 926 articles, of which 32 articles met the inclusion criteria for this review. Analyzing the epidemiological and Phylogenetic data from these articles, we found a considerable experimental and observational evidence of H3N8 equine influenza viruses infecting human being in different parts of the World in the past. Recently published articles from Pakistan and China have highlighted the emerging threat and capability of equine influenza viruses for an epidemic in human beings in future. In this review article we have summarized the salient scientific reports published on the epidemiology of equine influenza viruses and their zoonotic aspect. Additionally, several recent developments in the start of 21st century, including the transmission and establishment of equine influenza viruses in different animal species i.e. camels and dogs, and presumed encephalopathy associated to influenza viruses in horses, have documented the unpredictable nature of equine influenza viruses. In sum up, several reports has highlighted the unpredictable nature of H3N8 EIVs highlighting the need of continuous surveillance for H3N8 in equines and humans in contact with them for novel and threatening mutations.

Complementary therapies are the names given throughout the methods applied in parallel with modern medicine to gain the health of the individual. Interest in complementary therapies from the past to the present day and the frequency of use of these methods continues to increase. Increasing use of complementary therapies by the community and requiring patients to make appropriate and safe decisions in their own care requires that health care professionals have knowledge and skills in complementary therapies. In this context, nurses are expected to identify and develop their own practice of using complementary therapies, and to develop a strategy for these practices. Nurses integrating these practices into patient care and evaluating their outcomes ensure that the care provided to the patient is comprehensive and holistic. In order for these processes to take place, important policies must be established for nurses across the country. In the 1900s many countries developed politics and started to establish certificate programs and projects. Regarding national and international legislation, it is seen that legal regulations are not sufficient, especially for nurses. In this review, national and international legal arrangements for complementary therapies and the place of complementary therapies in nursing will be discussed.

With the search for petroleum deposits in the world pushing farther offshore each year, the oil industry has answered the call with the development of dynamically positioned drill ships, hole re-entry techniques, and subsea completions. These developments are helping make deep water oil recovery a reality. Now, more than ever, there is a need for accurate, long-range radiopositioning systems so that deep water surveys and well locations can be conducted with the required accuracy.Radiopositioning systems of the past decade include land-based systems such as Shoran, Raydist, Decca and Toran and the self- contained Satellite and Integrated systems. Recent developments for work in deeper water further offshore include Loran-C in the Range-Range mode and Differential Omega.


One of the most exciting recent developments in archaeology and history has been the adoption of new perspectives which see human societies in the past--as in the present--as made up of networks of interlinked individuals. This view of people as always connected through physical and conceptual networks along which resources, information, and disease flow, requires archaeologists and historians to use new methods to understand how these networks form, function, and change over time. The Connected Past provides a constructive methodological and theoretical critique of the growth in research applying network perspectives in archaeology and history and considers the unique challenges presented by datasets in these disciplines, including the fragmentary and material nature of such data and the functioning and change of social processes over long timespans. An international and multidisciplinary range of scholars debate both the rationale and practicalities of applying network methodologies, addressing the merits and drawbacks of specific techniques of analysis for a range of datasets and research questions, and demonstrating their approaches with concrete case studies and detailed illustrations. As well as revealing the valuable contributions archaeologists and historians can make to network science, the volume represents a crucial step towards the development of best practice in the field, especially in exploring the interactions between social and material elements of networks, and long-term network evolution.
