Los seres vivos estamos formados por moléculas orgánicas, proteínas, ácidos nucleicos, azúcares y grasas. Todos ellos son compuestos cuya base principal es el carbono. Los productos orgánicos están presentes en todos los aspectos de nuestra vida: la ropa que vestimos, los jabones, champús, desodorantes, medicinas, perfumes, utensilios de cocina, la comida, etc.
La química es el origen de la vida. Según la teoría más aceptada sobre el origen de la vida en la tierra, ésta surgió a partir de reacciones químicas hace miles de millones de años que dieron lugar a los primeros compuestos orgánicos a partir de compuestos inorgánicos, actualmente el gran problema que tenemos es conservar precisamente esa vida en el planeta, con este texto pretendemos contribuir a la comprensión de los efectos que algunos elementos químicos producen a la naturaleza y por ende el medio ambiente, para ir creando una cultura ambientalista en nuestros lectores.
Methadone and buprenorphine are the only two opioids that are indicated for the management of both pain and opioid-related drug addiction. Both present unique challenges to the general practitioner and pain specialist, requiring a separate analysis from the rest of the drugs in the same family. Handbook of Methadone Prescribing and Buprenorphine Therapy is an invaluable guide to the safe use of these opioids. Authored by clinical and academic leaders from a variety of settings and backgrounds, this book includes chapters on pharmacology, adverse effects, safe rotation from other opioids, cardiac toxicity, prescribing, pharmacokinetics, equianalgesic dose and replacement therapy. This comprehensive text provides clinicians, researchers, policy-makers and academicians a resource for all the relevant points in methadone prescribing and buprenorphine therapy.

Zoonotic diseases are infections that can be transmitted between people and animals. These infections are caused by microorganisms, such as viruses, bacteria, parasites, and fungi. Patients with zoonotic infections can experience severe and life-threatening illness, whilst others remain asymptomatic. For example, animals can harbor germs asymptomatically for long periods with no apparent impact on their own health. However, some microbes carried by animals can result in human illness, depending on the zoonotic disease. Furthermore, it is widely reported that almost 60% of human diseases are zoonotic, and at least 75% of the pathogens that cause diseases in humans are of zoonotic origin.
This open access book develops a framework for advancing agroecology transformations focusing on power, politics and governance. It explores the potential of agroecology as a sustainable and socially just alternative to today’s dominant food regime. Agroecology is an ecological approach to farming that addresses climate change and biodiversity loss while contributing to the Sustainable Development Goals. Agroecology transformations represent a challenge to the power of corporations in controlling food system and a rejection of the industrial food systems that are at the root of many social and ecological ills. In this book the authors analyse the conditions that enable and disable agroecol...
This new book presents important research in the field of ecological economics which is a trans-disciplinary field of academic research that addresses the dynamic and spatial interdependence between human economies and natural ecosystems. Ecological economics brings together and connects different disciplines, within the natural and social sciences but especially between these broad areas. Ecological economics presents a more pluralistic approach to the study of environmental problems and policy solutions, characterised by systems perspectives, adequate physical and biological contexts, and a focus on long-term environmental sustainability.
