Observing the Sun with Coronado™ Telescopes
At around the turn of the millennium, the introduction of the Coronado range of solar telescopes and filters heralded the ‘coming of age’ of amateur solar astronomy. Before then, solar astronomy was mostly white-light only. Hydrogen-alpha systems were expensive and difficult to use, but today even the budget-priced Coronado PST (Personal Solar Telescope) provides a band pass of one Angstrom and is thermally stable. That means that today’s amateur solar observers can see – and image – sunspots, flares, prominences, plage, filaments, and active regions of the Sun, all in amazing detail.

Noninvasive Imaging of Myocardial Ischemia
Non-invasive imaging plays a very important role in the assessment of patients investigated for coronary artery disease, providing valuable information for diagnosis and aiding management decisions. It covers a broad spectrum of investigations including radionuclide imaging, echocardiography, magnetic resonance imaging and computed tomography. Progress towards the most efficacious means of assessing a patient is relentless, with recent years seeing an important shift in emphasis from invasive to noninvasive techniques. This informative book compares the various modalities in a practical diagnostic environment. It thus provides a forum for fertile discussion, bringing the discussion of these various methodologies together in one reference for the first time. The narrative flow is unique and will ensure that all levels of medical practitioners with an interest in cardiac imaging will find this an unparalleled resource for use in guiding their practice.
New Frontiers in Lifestyle-Related Diseases
Akiyoshi Hosoyamada, M.D., Ph.D. President, Showa University Tokyo, Japan September 2007 v Preface The leading cause of death in Western countries and some developing countries is atherosclerotic cardiovascular diseases. Among them, acute myocardial infarction is the most common type of fatal disease, caused by the progression of atherosclerosis characterized by accumulation of choles terol in vascular walls. Development of atherosclerosis is greatly enhanced by major risk factors for cardiovascular diseases such as obesity, hyperlip idemia, diabetes (hyperglycemia), and hypertension. Among those, obesity frequently initiates a metabolic change that subsequently induces hyperlip idemia, diabetes, hypertension, and eventually atherosclerotic cardiovascu lar diseases. Because obesity and its related disorders largely depend on lifestyle factors such as high calorie intake and low physical activity, a series of disorders are termed lifestyle-related diseases.
NEURO-COVID-19 : Neuroinvasive potential and neurological complications of SARS-CoV-2
From the earliest days of the COVID-19 pandemic, there have been reports of significant neurological and psychological symptoms following SARS-CoV-2 infection. This research paper is designed to examine the potential psychoneuroendocrine pathogenic mechanisms by which SARS-CoV-2 elicits psychiatric sequelae, as well as to posit potential pharmacologic strategies to address and reverse these pathologies. Following a brief overview of the presence and prevalence of neuropsychiatric manifestation in COVID-19 patients, we address mechanisms by which SARS-CoV-2 could enter or otherwise elicit changes in the CNS.
Multi-slice and Dual-source CT in Cardiac Imaging : Principles - Protocols - Indications - Outlook
Cardiac diseases, and in particular coronary artery disease, are the leading cause of death and morbidity in industrialized countries. The development of non-invasive imaging techniques for the heart and the coronary arteries has been considered a key element in improving patient care. A breakthrough in cardiac imaging using CT occurred in 1998, with the introduction of multi-slice computed tomography (CT). Since then, amazing advances in performance have taken place with scanners that acquire up to 64 slices per rotation. This book discusses the state-of-the-art developments in multi-slice CT for cardiac imaging as well as those that can be anticipated in the future

Mente e Cuore : Clinica psicologica della malattia cardiaca = Mind and heart : Psychological Clinic of Heart Disease
Recent data has shown that there is a relationship between psychological conditions and heart disease. Furthermore, psychological interventions on patients with coronary heart disease (CHD) can reduce heart risk and improve their quality of life. This volume, which is the result of collaboration with the most committed international researchers in the field of clinical psychology and health applied to heart disease, presents an updated and complete overview of scientific research in this area. The first part of the volume presents the psychological pictures and relational aspects associated with heart disease with a particular focus on personality traits. The second part illustrates the psychological interventions in cardiac rehabilitation that research has shown to be effective in reducing cardiac risk. This text can be a useful reference to the practice of doctors, psychologists and health professionals who want to understand and deepen the link between heart disease and psychological aspects.

Impact of COVID-19 on the dental community
The COVID-19 pandemic is considered to be a global public health emergency. Due to its route of transmission via contact with droplets and aerosols, dentists are at high risk of acquiring an infection while treating patients. The impact of the coronavirus on the dental community is eminent, and the greatest challenge is how we can offer dental treatment despite the outbreak. Dental education programs in both under- and postgraduate forms will also suffer from the ramifications of the pandemic. This topical collection offers many perspectives on the management of the COVID-19 crisis within the dental community.
Homocysteine
Homocysteine is a non-proteinogenic α-amino acid. It is a homologue of the amino acid cysteine, differing by an additional methylene bridge (-CH2-). It is biosynthesized from methionine by the removal of its terminal methyl group. In the body, Homocysteine (HCY) can be recycled into methionine or converted into cysteine with the aid of certain B-vitamins. A high level of Homocysteine in the blood (hyperhomocysteinemia) makes a person more prone to endothelial cell injury, which leads to inflammation in the blood vessels, which in turn may lead to atherogenesis, which can result in ischemic injury. Therefore, hyperhomocysteinemia is a possible risk factor for coronary artery disease (CAD). Coronary artery disease occurs when an atherosclerotic plaque blocks blood flow to the coronary arteries, which supply the heart with oxygenated blood.
Heart block
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle. It is involuntary, striated muscle that constitutes the main tissue of the wall of the heart. The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall (the pericardium) and the inner layer (the endocardium), with blood supplied via the coronary circulation. It is composed of individual cardiac muscle cells joined together by intercalated discs, and encased by collagen fibers and other substances that form the extracellular matrix.

Extra-coronal restorations : Concepts and clinical application
A clinical guide to contemporary materials and techniques for the restoration of individual teeth and implants. It fully reflects the important developments in the field over the past 15 years, including in particular the shift away from wholesale use of crowns towards adhesive dentistry and less invasive extra-coronal restorations. The book opens by considering the principles and evidence base relating to the longevity of restorations of teeth and implants. Importantly, it explains how to ensure "a healthy start" and manage future risks. Material choice and aesthetic issues are then discussed, before all aspects of the planning and provision of extra-coronal restorations are examined in depth. The coverage also includes the adaptation of crowns to existing partial dentures. In line with modern dental education, each chapter begins with clinically relevant learning objectives, and helpful clinical tips are highlighted.
