Buch. Condizione: Neu. Neuware -Evolving Strategies in Peritoneal Dialysis is intended as a concise compilation of articles designed to understand the basics of the current practice of the most cost-effective form of life support for patients with end-stage renal disease who require dialysis. Current strategies are understood best with a review of the historical development of catheter materials, solution packaging, and simplified machinery, which allow safe and effective nocturnal treatments. Quantitation of the efficacy of peritoneal dialysis is also reviewed because such calculations were also developed by the pioneers of nephrology to ensure adequacy of dialysis and daily fluid balance, which are responsible for the best chance for long-term patient survival. Comparison of methods for catheter placement is presented as well as the role that a dialysis center plays in the health and success of this form of end-stage renal disease patient care. The novel concept of assisted peritoneal dialysis for the infirm or institutionalized patients is probably the next direction needed to make available this treatment to many more patients than are currently eligible to receive it. This concept is explored in a separate chapter. Finally, professional dialysis staff must monthly assess individuals' nutritional status, bone health, and infection prevention and treatment to ensure the greatest functional status for these patients. This book concludes with a review of each of these topics to expand the mandatory monthly surveillance performed by dialysis centers for each patient who receives home peritoneal dialysis therapy.Books on Demand GmbH, Überseering 33, 22297 Hamburg 114 pp. Englisch.

Buch. Condizione: Neu. Neuware -The term extreme weather normally conjures up thoughts of massive storms or heat waves or overtly cold temperatures. These are all examples of what we might consider as weather events that occur out of the ordinary or what is regarded as the normal pattern of calm, heat, cold, dry, or wet conditions for one season of the year or another. The point is that if we consider an oscillation of data points in a weather pattern and plot a mean through it, extreme weather can be observed as a perturbation in a distribution of climatic events over time. These events may be short-lived, such as a wind gust occurrence, or of longer duration, such as heavy rain leading to flooding. Importantly, once initiated, a perturbation event has an associated consequence, which usually requires human intervention to rectify the event¿s consequences.Books on Demand GmbH, Überseering 33, 22297 Hamburg 152 pp. Englisch.

Buch. Condizione: Neu. Neuware -DNA damage response (DDR) and lesion repair are vital processes ensuring genome integrity through various pathways depending mainly on the nature of DNA injury and cell cycle stage. DDR is finely regulated at many levels in co-ordination with other ongoing processes as is genome replication and cell cycle progression. Posttranslational modifications (PTMs), affecting both protein-protein and protein-DNA interactions, play a crucial role in finely tuning all processes involved in the restoration of genome lesions. Regarding damaged chromatin, PTMs serve in many cases as recruitment platforms for DNA repair mechanisms by facilitating binding sites or regulating interactions between involved proteins. Ubiquitination, the addition of ubiquitin moieties on a target protein, apart from controlling protein availability through degradation, is also involved, together with partner small ubiquitin-like modifier (SUMO), in controlling many pathways involved in DDR by modifying the structure-function relationship and thus interacting with partner molecules. The aim of this book is to cover a broad spectrum of current topics in ubiquitination and to a lesser extent SUMOylation involvement in regulation of DDR and repair in health and disease. This book is intended for pre- and postgraduate students and young scientists in this field. Members of both academic and research institutions, actively involved in the field, have described their current understanding of major mechanisms involved, highlighted key events, described ongoing applications in both developmental diseases and cancer and provided hints for future potential applications.Books on Demand GmbH, Überseering 33, 22297 Hamburg 220 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Global wheat consumption in the 2016/2017 season is forecasted to reach a record high 736m tonnes, showing a growth of 25% in the last 15 years. This raises the question which outlets the wheat is going into, what the growth of these outlets is, which regions or countries have grown the most, and where do we see future potential. Strong competition of other feed grains like corn is expected to slow the growth of wheat used for feed in the next years, and in the future, companies involved in the grain supply chain and feeding industry will need to be flexible enough to continue to meet this fast-changing demand for feed grains. For feed producers, this means they need to be able to access supplies of different grains from different origins to allow for the cheapest composition of their feed, while grain suppliers need to be able to continuously best engage with global trading opportunities to originate grains in various regions and move them to demand regions as cost-effectively as possible. 250 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Hyperbaric oxygen treatment (HBO2) is a widely accepted adjuvant therapy in various health conditions that exhibit impaired tissue blood flow. At high pressures, the delivery of the dissolved oxygen in plasma is enhanced, which contributes to better tissue oxygenation, cellular metabolism and ultimately, healing. However, this is not the only beneficial outcome of HBO2 treatment since oxygen is a highly reactive molecule and can induce upregulation of many enzymatic systems in the cell at the cellular, genetic and molecular level. Particularly, vascular/endothelial function is affected by the HBO2. Our understanding of these mechanisms is still emerging. There have been many controversies related to the HBO2 protocols and indications. As well as exhibiting beneficiary effects on the tissue perfusion, it is known that HBO2 demonstrates high toxicity at higher pressures, due to increased oxidative stress and barotrauma. On the other hand, there is a lack of translation of the knowledge on the mechanisms of action of HBO2 obtained from the experimental research to the clinical practice. Thus, this book presents the reader with an overview of the current knowledge on the mechanisms of HBO2 effects in various experimental models and clinical treatment protocols, in an attempt to provide a better understanding of how and when HBO2 should be used as an effective therapy without unwanted side effects. 130 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long-term management of aquatic resources all over the world, efforts have met with limited success. Thus, the sustainable use of aquatic resources has become a very important reality considering a projected human population of 11 billion by the year 2100. With this reality in mind, the purpose of this book is to shed more light on the field of marine ecology by emphasizing the diversity of aquatic life on earth and its importance both as part of a balanced ecosystem and as part of critical source of food on earth. The book covers important findings, discussions and reviews on a variety of subjects on environmental and competitive interactions of marine organisms at different trophic levels and their effects on the productivity, dynamics and structure of marine ecosystems around the world. Each chapter focuses on a specific case in the field of marine ecology and was written by researchers with years of experience in their respective fields. We hope that academicians, researchers and students as well as experts and professionals working in the field of marine ecology will benefit from these contributions. We also hope that this book will inspire more studies to help better understand the marine environment and develop strategies to better protect this crucial element of life on earth. 294 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Measurements in present experiments have dramatically advanced our understanding of ultrahigh-energy cosmic rays. The suppression of the flux at the highest energies is now confirmed without any doubt, and strong limits have been placed on the photon and neutrino components. There are indications for a small, large-scale anisotropy both below and above the energy of the angle and for a correlation on smaller angular scales at E > 5.5\*1019 eV. Around 3\*1018 eV, there is a distinct change of slope with energy, and the shower-to-shower variance decreases. Interpreted with the leading LHC-tuned shower models, this implies a gradual shift to a heavier composition, and a number of fundamentally different astrophysical model scenarios have been developed to describe this evolution. 172 pp. Englisch.
