Available in PDF, EPUB and Kindle. Book excerpt: The instant New York Times bestseller | A Washington Post Notable Book | One of NPR's Best Books of the Year “Expert storytelling . . . [Pollan] masterfully elevates a series of big questions about drugs, plants and humans that are likely to leave readers thinking in new ways.” —New York Times Book Review From #1 New York Times bestselling author Michael Pollan, a radical challenge to how we think about drugs, and an exploration into the powerful human attraction to psychoactive plants—and the equally powerful taboos. Of all the things humans rely on plants for—sustenance, beauty, medicine, fragrance, flavor, fiber—surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable. So, then, what is a “drug”? And why, for example, is making tea from the leaves of a tea plant acceptable, but making tea from a seed head of an opium poppy a federal crime? In This Is Your Mind on Plants, Michael Pollan dives deep into three plant drugs—opium, caffeine, and mescaline—and throws the fundamental strangeness, and arbitrariness, of our thinking about them into sharp relief. Exploring and participating in the cultures that have grown up around these drugs while consuming (or, in the case of caffeine, trying not to consume) them, Pollan reckons with the powerful human attraction to psychoactive plants. Why do we go to such great lengths to seek these shifts in consciousness, and then why do we fence that universal desire with laws and customs and fraught feelings? In this unique blend of history, science, and memoir, as well as participatory journalism, Pollan examines and experiences these plants from several very different angles and contexts, and shines a fresh light on a subject that is all too often treated reductively—as a drug, whether licit or illicit. But that is one of the least interesting things you can say about these plants, Pollan shows, for when we take them into our bodies and let them change our minds, we are engaging with nature in one of the most profound ways we can. Based in part on an essay published almost twenty-five years ago, this groundbreaking and singular consideration of psychoactive plants, and our attraction to them through time, holds up a mirror to our fundamental human needs and aspirations, the operations of our minds, and our entanglement with the natural world.

Download or read book Anatomy Age and Ecology of High Mountain Plants in Ladakh the Western Himalaya written by Jiří Doležal and published by Springer. This book was released on 2018-07-02 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This aesthetically unique book combines ecological, morphological and anatomical, as well as phylogenetic studies on plant material in a largely unexplored dry mountain region above the timberline. It offers the first comparative analysis of hundreds of plants - annuals, perennial herbs and dwarf shrubs - in an area of 87,000 km2 at altitudes from 2600 to 6150 m above sea level in the Western Himalaya. Characteristic landscape pictures of all major vegetation types and maps show at which locations and altitudes the individual species of vascular plants are distributed, while macroscopic plant pictures and plant age are related to high-quality micro-sections and micro-photographs. The anatomical features of 345 dicotyledons were characterized using the published coding systems and those of 155 monocotyledones were characterized on the basis of a newly developed key. The number of annual rings and anatomical features of the xylem and phloem of dicots are compared and related to different ecological conditions within this extremely dry and cold environment. The ecological and anatomical characterization is used to create a phylogenetic tree based on nucleotide sequences, and indicates which features are genetically stable and which ones are modified by environmental factors. The book appeals to scientists in the fields of plant taxonomy, morphology, anatomy and ecology.

Download or read book Ecophysiology of High Salinity Tolerant Plants written by M. Ajmal Khan and published by Springer Science & Business Media. This book was released on 2006-05-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.
Download or read book Nitrogen Acquisition and Assimilation in Higher Plants written by Sara Amancio and published by Springer Science & Business Media. This book was released on 2005-02-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth. During the green revolution nitrogenfertilisation was responsible for spectacular yield increases. At present yield is balanced with commitments towards the environment and sustainable agriculture. For agro-biotechnology comprehensive knowledge of plant functioning is needed. Yield improvement and accumulation of essential nitrogen compounds is relying on selection and gene technologies. Research on the uptake, acquisition and assimilation of nitrogen, as well as the synthesis and storage of reserve and defence N-compounds, therefore, is essential. The third volume in the Plant Ecophysiology series integrates functional and molecular physiology with ecophysiological and sustainable agricultural approaches to get a better understanding of the regulation and the impact of environmental and stress signals on nitrogen acquisition and assimilation. The book is of interest for advanced students and junior researchers and supplies comprehensive information for scientists working in the field of nitrogen metabolism and readers interested in sustainable development.
Download or read book Multiple Abiotic Stress Tolerances in Higher Plants written by N.K. Gupta and published by CRC Press. This book was released on 2023-10-03 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 50 years, classical breeding has played a significant role in achieving higher crop productivity, but major crops have reached a plateau in their yield potential. Therefore, the current focus for sustainable intensification of agriculture is the use of biotechnological approaches to enhance the yield potential by combating the yield losses that occur due to abiotic stresses. The abiotic stresses are governed by multigenes, and therefore, a holistic approach is needed to get success in imparting stress tolerance to enhance the yield potential of our crops. Plants face multiple stress conditions during their life stages and adopt several physiological, biochemical, and molecular strategies to combat that, which are sometimes not sufficient to survive, particularly crop plants. The climate change era has created a need to understand the abiotic stresses in a holistic way. Therefore, a deep understanding of multiple abiotic stress mechanisms is necessary to develop crops tolerant to climate fluctuation. With this background, the outline of this book covers the following features: • Agriculture sustainability and molecular understanding of multiple stress tolerance • Systems biology for life-history strategies, conventional and genomic approaches above and underground • Genetic resources and molecular understanding of seed priming • Molecular signaling compounds, cell signal transduction, and crosstalk between plant growth hormones and regulators • Roles Transcription factors, LEA proteins, reactive oxygen species and alternative oxidase • Genome editing, metabolomics, and ‘omics’ technologies
Download or read book Antioxidants and Antioxidant Enzymes in Higher Plants written by Dharmendra K. Gupta and published by Springer. This book was released on 2018-03-10 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of antioxidants and antioxidant enzymes and their role in the mechanisms of signaling and cellular tolerance under stress in plant systems. Major reactive oxygen species (ROS)-scavenging/modulating enzymes include the superoxide dismutase (SOD) that dismutates O2 into H2O2, which is followed by the coordinated action of a set of enzymes including catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and peroxiredoxins (Prx) that remove H2O2. In addition to the ROS scavenging enzymes, a number of other enzymes are found in various subcellular compartments, which are involved in maintaining such redox homeostasis either by directly scavenging particular ROS and ROS-byproducts or by replenishing antioxidants. In that respect, these enzymes can be also considered antioxidants. Such enzymes include monodehydroascorbate reductase (MDAR), dehydroascorbate reductase (DHAR), glutathione reductase (GR), alternative oxidases (AOXs), peroxidases (PODs) and glutathione S-transferases (GSTs). Some non-enzymatic antioxidants, such as ascorbic acid (vitamin C), carotenes (provitamin A), tocopherols (vitamin E), and glutathione (GSH), work in concert with antioxidant enzymes to sustain an intracellular steady-state level of ROS that promotes plant growth, development, cell cycles and hormone signaling, and reinforces the responses to abiotic and biotic environmental stressors. Offering a unique compilation of information on antioxidants and antioxidant enzymes, this is a valuable resource for advanced students and researchers working on plant biochemistry, physiology, biotechnology, and signaling in cell organelles, and those specializing in plant enzyme technology.

Download or read book The Invention of Surgery written by David Schneider and published by Simon and Schuster. This book was released on 2020-03-03 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by an author with plenty of experience holding a scalpel, Dr. David Schneider’s The Invention of Surgery is an in-depth biography of the practice that has leapt forward over the centuries from the dangerous guesswork of ancient Greek physicians through the world-changing developments of anesthesia and antiseptic operating rooms to the “implant revolution” of the twentieth century.The Invention of Surgery is history of surgery that explains this dramatic, world-changing progress and highlights the personalities of the discipline's most dynamic historical figures. It links together the lives of the pioneering scientists who first understood what causes disease and how surgery could powerfully intercede in people’s lives, and then shows how the rise of surgery intersected with many of the greatest medical breakthroughs of the last century. And as Schneider argues, surgery has not finished transforming; new technologies are constantly reinventing both the practice of surgery and the nature of the objects we are permanently implanting in our bodies. Schneider considers these latest developments, asking “What’s next?” and analyzing how our conception of surgery has changed alongside our evolving ideas of medicine, technology, and our bodies.

Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive guide to the botany, history, distribution, and cultivation of all known psychoactive plants • Examines 414 psychoactive plants and related substances • Explores how using psychoactive plants in a culturally sanctioned context can produce important insights into the nature of reality • Contains 797 color photographs and 645 black-and-white illustrations In the traditions of every culture, plants have been highly valued for their nourishing, healing, and transformative properties. The most powerful plants--those known to transport the human mind into other dimensions of consciousness--have traditionally been regarded as sacred. In The Encyclopedia of Psychoactive Plants Christian Rätsch details the botany, history, distribution, cultivation, and preparation and dosage of more than 400 psychoactive plants. He discusses their ritual and medicinal usage, cultural artifacts made from these plants, and works of art that either represent or have been inspired by them. The author begins with 168 of the most well-known psychoactives--such as cannabis, datura, and papaver--then presents 133 lesser known substances as well as additional plants known as “legal highs,” plants known only from mythological contexts and literature, and plant products that include substances such as ayahuasca, incense, and soma. The text is lavishly illustrated with 797 color photographs--many of which are from the author’s extensive fieldwork around the world--showing the people, ceremonies, and art related to the ritual use of the world’s sacred psychoactives.
