Cellebiologi (cytologi)

Die Patch-Clamp-Technik ist heute eine der wichtigsten neurophysiologischen Arbeitsmethoden. Ihre Anwendung hat in der biomedizinischen Grundlagenforschung bedeutende Erkenntnisse über die Funktion und die Eigenschaften von Ionenkanälen erbracht, und auch aus der angewandten pharmakologischen Forschung ist sie in­zwischen nicht mehr wegzudenken. Klar und praxisbezogen vermitteln die Autoren die wesentlichen Informationen, um die Methode im Labor einzuführen und erfolgreich anzuwenden. Das Buch erläutert die theoretischen Grundlagen der Messung, den detaillierten Aufbau eines Messplatzes und die praktische Durchführung typischer Messkonfigurationen. Konkrete Tipps und Tricks helfen beim ¿Trouble-Shooting¿ und sind nicht nur für Neuanwender eine unverzichtbare Hilfe.

This detailed edition reflects the significant new findings in the components of permeability barriers and how they work in different tissues with a collection of cutting-edge techniques. Chapters explore the formation, maintenance, regulation, and dynamics of permeability barriers in an effort to push the boundaries of the field. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Permeability Barrier: Methods and Protocols, Second Edition serves as an invaluable guide for both experts but novices in the stem cell field and other related areas of research.

Angiotensin: From the Kidney to Coronavirus, a new volume in the Molecular Mediators in Health and Disease series, presents the communication role of the hormone in both health and disease states. Beyond the most common conditions, the book also explores the role of Angiotensin in infectious diseases, like COVID-19. Sections provide background to its discovery and role in homeostasis, focus on molecular biology aspects, including genetics and measurements of its associated proteins, describe the specific actions of angiotensin in normal physiology with different organ systems, survey different classes of drugs that act on the Renin-angiotensin-aldosterone system, cover non-angiotensin II peptides, and more. The final part of the book is dedicated to angiotensin's role in disease states, making this the ideal reference for researchers in life sciences interested in understanding the physiological role of Angiotensin in a complete fashion. Research physicians will also benefit from the book's complete coverage of organ systems and diseases where Angiotensin plays a key role.

The Chemical Dialogue Between Plants and Beneficial Microorganisms provides foundational insights on plant beneficial microorganisms and their impact on the health and productivity of plants. Providing in-depth and recent updates about unexplored aspects of plant microbes interactions, the book includes the biological repertoire of arbuscular mycorrhizal association, molecular architecture of Rhizobium-plant symbiosis, and endophytes in transcriptional plasticity during host colonization by endophytes. The book also includes details about the mechanism of different plant beneficial microorganisms, how these differ, and their cross signaling. This book will be an important reference for researchers working on different plant beneficial microorganisms and their molecular arsenal.

During the last two decades, the prevalence of obesity has dramatically increased in western and westernized societies. Its devastating health consequences include hypertension, cardiovascular diseases, or diabetes and make obesity the second leading cause of unnecessary deaths in the USA. As a consequence, obesity has a strong negative impact on the public health care systems. Recently emerging scienti?c insight has helped understanding obesity as a complex chronic disease with multiple causes. A multileveled gene-environment interaction appears to involve a substantial number of susceptibility genes, as well as associations with low physical activity levels and intake of high-calorie, low-cost, foods. Unfor- nately, therapeutic options to prevent or cure this disease are extremely limited, posing an extraordinary challenge for today's biomedical research community. Obesity results from imbalanced energy metabolism leading to lipid storage. Only detailed understanding of the multiple molecular underpinnings of energy metabolism can provide the basis for future therapeutic options. Numerous aspects of obesity are currently studied, including the essential role of neural and endocrine control circuits, adaptive responses of catabolic and anabolic pathways, metabolic fuel sensors, regulation of appetite and satiation, sensory information processing, transcriptional control of metabolic processes, and the endocrine role of adipose tissue. These studies are predominantly fuelled by basic research on mammalian models or clinical studies, but these ?ndings were paralleled by important insights, which have emerged from studying invertebrate models.

Induced Pluripotent Stem (iPS) cells are mature cells that have been genetically reprogrammed so that they return to their embryonic state. It is not yet known if iPS stem cells and embryonic stem cells differ significantly. Today many fundamental belief systems in biology are shifting towards accepting that mature body cells can be reverted to an embryonic state without the help of eggs or embryos. With their changed identities, iPS cells are then ready to serve as new tools for research in the fields of disease pathogenesis, drug discovery, oncology, and cell transplantation. One example of this would be using iPS from a patient's mature cells to repair damaged tissue; it is thought that there would be very low incidence of rejection of the 'new' tissue in these cases. For the last four years, this therapeutic promise has been studied by hundreds of researchers worldwide in an effort to understand the ability of these cells to reverse their biological clocks.
