Silent Myocardial Ischemia in Master Marathon Runner | Chapter 08 | New Insights into Disease and Pathogen Research Vol. 1

Silent myocardial ischemia is defined as objective documentation of myocardial ischemia in the absence of angina or anginal equivalents. Silent myocardial ischemia is quite different from silent coronary artery disease. The symptomatic angina is the tip of the ischemic iceberg and it is less frequent in athletes  than in non-athletes. Athletes change their perception of ischemic stimulus and increasing pain threshold from increased circulating endorphin levels.  Silent  myocardial  ischemia  is  more  prevalent  than angina in patients with coronary artery disease, and athletes are not immune to it. In  order  to  discover  early  stages  of malignant neoplasia (e.g. breast and colon cancer) in the asymptomatic  stage and  thus  prevent  reaching  final  stages  of the  disease, screening participation has been widely accepted. Vice versa,  although atherosclerotic cardiovascular disease  causes  more  deaths and disabilities  than  all   causes  of  death  correlated  to  cancer, there  are  no  precise  guidelines  concerning  the  screening  of asymptomatic  elements  suffering  from  atherosclerosis. There are a number of reports of exercise-related sudden deaths and myocardial infarctions in aerobically trained athletes suffering from exercise - induced silent myocardial ischemia. The most appropriate and common method to discover silent myocardial ischemia is exercise stress testing. Therefore, in this chapter  the authors describe three emblematic cases of silent myocardial ischemia detected in master marathon runners during systematic pre-participation screening. These marathon runners were asymptomatic but were suffering from a severe coronary artery disease that was detected only thanks to exercise treadmill stress test, and were then properly treated. Silent myocardial ischemia is not such a rare event in athletes, indeed quite the opposite. In fact, even though athletes are asymptomatic this does not exclude the possibility that they are suffering from severe coronary artery disease.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t
