La prueba del cielo: el viaje de un neurocirujano a la vida después de la muerte
by Eben AlexanderMiles de personas han tenido experiencias cercanas a la muerte, pero los científicos han sostenido de que son imposibles. El doctor Eben Alexander era uno de esos científicos. Un neurocirujano altamente entrenado, Alexander sabía que las experiencias cercanas a la muerte se sienten reales, pero que simplemente son fantasías producidas por el cerebro bajo un estrés extremo. Luego, el cerebro del propio doctor Alexander fue atacado por una extraña enfermedad. La parte del cerebro que controla los pensamientos y las emociones —y en esencia nos hace humanos— se le apagó por completo. Estuvo en coma durante siete días. Entonces, mientras sus médicos consideraban parar su tratamiento, los ojos de Alexander se abrieron. Volvió. La recuperación de Alexander es un milagro médico. Pero el verdadero milagro de su historia yace en otro lugar. Mientras su cuerpo estaba en coma, Alexander viajó más allá de este mundo y se encontró con un ser angelical que lo guió a los terrenos más profundos de la existencia suprafísica. Allá conoció a, y habló con, la fuente Divina del universo. La historia de Alexander no es una fantasía. Antes de comenzar su viaje, no podía reconciliar su conocimiento de la neurociencia con ninguna creencia del cielo, Dios ni el alma. Hoy en día, Alexander es un médico que cree que la verdadera salud se puede adquirir solo cuando nos damos cuenta de que Dios y el alma son reales y la muerte no es el final de la existencia personal, sino solo una transición. Esta historia sería extraordinaria sin importar a quién le haya ocurrido. Que le haya ocurrido al doctor Alexander la hace revolucionaria. Ningún científico ni persona de fe la podrá ignorar. Leerla te cambiará la vida.

Label-Free Biosensor Methods in Drug Discovery
by Ye FangThis volume explores label-free biosensors, advantageous in part because this technology bypasses the need of labels, reporters, and cell engineering, all of which are common to labeled techniques but may introduce artifacts in assay results. Addressing several fundamental and practical aspects as to how to implement label-free methods in the drug discovery process, this book covers a wide range of topics, including binding kinetics determination, fragment screening, antibody epitope mapping, protein-protein interaction profiling and screening, receptor pathway deconvolution, drug pharmacology profiling and screening, target identification, drug toxicity assessment, and physical phenotype profiling and diagnostics based on various cellular processes such as cell adhesion, migration, invasion, infection, and inflammation. As part of the Methods in Pharmacology and Toxicology series, chapters aim to provide key detail and implementation advice to aid with progress in the lab. Practical and thorough, Label-Free Biosensor Methods in Drug Discovery provides a new avenue for rapid access to a focused collection of highly regarded contributions in the field.
Label-Free Monitoring of Cells in vitro (Bioanalytical Reviews #2)
by Joachim WegenerThis book is dedicated to label-free, non-invasive monitoring of cell-based assays and it comprises the most widely applied techniques. Each approach is described and critically evaluated by an expert in the field such that researchers get an overview on what is possible and where the limitations are. The book provides the theoretical basis for each technique as well as the most successful and exciting applications.Label-free bioanalytical techniques have been known for a long time as valuable tools to monitor adsorption processes at the solid-liquid interface in general – and biomolecular interaction analysis (BIA) in particular. The underlying concepts have been progressively transferred to the analysis of cell-based assays. The strength of these approaches is implicitly given with the name 'label-free': the readout is independent of any label, reagent or additive that contaminates the system under study and potentially affects its properties. Thus, label-free techniques provide an unbiased analytical perspective in the sense that the sample is not manipulated by additives but pure. They are commonly based on physical principles and read changes in integral physical properties of the sample like refractive index, conductivity, capacitance or elastic modulus to mention just a few. Even though it is not implied in the name, label-free approaches usually monitor the cells under study non-invasively meaning that the amplitude of the signal (e.g. electric field strength, mechanical elongation) that is used for the measurement is too low to interfere or affect. In contrast to label-based analytical techniques that are commonly restricted to a single reading at a predefined time point, label-free approaches allow for a continuous observation so that the dynamics of the biological system or reaction become accessible.
Label-Free Super-Resolution Microscopy (Biological and Medical Physics, Biomedical Engineering)
by Vasily AstratovThis book presents the advances in super-resolution microscopy in physics and biomedical optics for nanoscale imaging. In the last decade, super-resolved fluorescence imaging has opened new horizons in improving the resolution of optical microscopes far beyond the classical diffraction limit, leading to the Nobel Prize in Chemistry in 2014. This book represents the first comprehensive review of a different type of super-resolved microscopy, which does not rely on using fluorescent markers. Such label-free super-resolution microscopy enables potentially even broader applications in life sciences and nanoscale imaging, but is much more challenging and it is based on different physical concepts and approaches. A unique feature of this book is that it combines insights into mechanisms of label-free super-resolution with a vast range of applications from fast imaging of living cells to inorganic nanostructures. This book can be used by researchers in biological and medical physics. Due to its logically organizational structure, it can be also used as a teaching tool in graduate and upper-division undergraduate-level courses devoted to super-resolved microscopy, nanoscale imaging, microscopy instrumentation, and biomedical imaging.
Label-Free Technologies For Drug Discovery
by Matthew Cooper Lorenz M. MayrOver the past two decades the benefits of label-free biosensor analysis have begun to make an impact in the market, and systems are beginning to be used as mainstream research tools in many drug discovery laboratories.Label-Free Technologies For Drug Discovery summarises the latest and emerging developments in label-free detection systems, their underlying technology principles and end-user case studies that reveal the power and limitations of label-free in all areas of drug discovery.Label-free technologies discussed include SPR, NMR, high-throughput mass spectrometry, resonant waveguide plate-based screening, transmitted-light imaging, isothermal titration calorimetry, optical and impedance cell-based assays and other biophysical methods. The technologies are discussed in relation to their use as screening technologies, high-content technologies, hit finding and hit validation strategies, mode of action and ADME/T, access to difficult target classes, cell-based receptor/ligand interactions particularly orphan receptors, and antibody and small molecule affinity and kinetic analysis.Label-Free Technologies For Drug Discovery is an essential guide to this emerging class of tools for researchers in drug discovery and development, particularly high-throughput screening and compound profiling teams, medicinal chemists, structural biologists, assay developers, ADME/T specialists, and others interested in biomolecular interaction analysis.
Labeling the Mentally Retarded: Clinical and Social System Perspectives on Mental Retardation
by Jane R. MercerThis eight-year study of an American city traces the answer to the question "Who is retarded?" by analyzing the labeling process in a large number of community agencies. Data for the study are drawn from a representative sample of 7,000 persons under fifty years of age who were tested ans screened for "symptoms" of mental retardation. The author finds that that schools label more persons as mentally retarded than any other agency and share their labels more widely with others in the community. Relying on IQ test scores for diagnosis, schools place many persons with scores above 70 and with no physical disabilities in the role of retardate. The author contends that both the statistical model of "normal" and the unicultural viewpoint of educators and clinicians work to the disadvantage of the poor and the ethnic minorities. Given the opportunity, many persons demonstrate by their ability to cope with the problems in other areas of life that they are not comprehensively incompetent. The author makes serval policy recommendations. First, she suggests lowering the IQ score cutoff point used by schools in determining who shall be labeled as retarded. Second, she recommends that the clinicians use the two-dimensional definition of retardation proposed by the American Association of Mental Deficiency, subnormality in both intellectual performance and adaptive behavior. Third, she concludes that pluralistic assessment procedures must be employed to take into account cultural biases in IQ tests designed to measure cognitive skills. This title is part of UC Press's Voices Revived program, which commemorates University of California Press's mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1973.

Labor of Love: Gestational Surrogacy and the Work of Making Babies
by Heather JacobsonWhile the practice of surrogacy has existed for millennia, new fertility technologies have allowed women to act as gestational surrogates, carrying children that are not genetically their own. While some women volunteer to act as gestational surrogates for friends or family members, others get paid for performing this service. The first ethnographic study of gestational surrogacy in the United States, Labor of Love examines the conflicted attitudes that emerge when the ostensibly priceless act of bringing a child into the world becomes a paid occupation. Heather Jacobson interviews not only surrogate mothers, but also their family members, the intended parents who employ surrogates, and the various professionals who work to facilitate the process. Seeking to understand how gestational surrogates perceive their vocation, she discovers that many regard surrogacy as a calling, but are reluctant to describe it as a job. In the process, Jacobson dissects the complex set of social attitudes underlying this resistance toward conceiving of pregnancy as a form of employment. Through her extensive field research, Jacobson gives readers a firsthand look at the many challenges faced by gestational surrogates, who deal with complicated medical procedures, delicate work-family balances, and tricky social dynamics. Yet Labor of Love also demonstrates the extent to which advances in reproductive technology are affecting all Americans, changing how we think about maternity, family, and the labor involved in giving birth.

Laboratory Guide to Enzymology
by Geoffrey A. Holdgate Antonia Turberville Alice LanneLABORATORY GUIDE TO ENZYMOLOGY An accessible guide to understanding the foundations of enzymology at its application in drug discovery Enzymes are highly specialized proteins necessary for performing specific biochemical reactions essential for life in all organisms. In disease, the functioning of these enzymes can become altered and, therefore, enzymes represent a large class of key targets for drug discovery. In order to successfully target dysfunctional enzymes pharmaceutically, the unique mechanism of each enzyme must be understood through thorough and in-depth kinetic analysis. The topic of enzymology can appear challenging due its interdisciplinary nature combining concepts from biology, chemistry, and mathematics. Laboratory Guide to Enzymology brings together the theory of enzymology and associated lab-based work to offer a practical, accessible guide encompassing all three scientific disciplines. Beginning with a brief introduction to proteins and enzymes, the book slowly immerses the reader into the foundations of enzymology and how it can be used in drug discovery using modern methods of experimentation. The result is a detailed but highly readable volume detailing the basis of drug discovery research. Laboratory Guide to Enzymology readers will also find: Descriptions of key concepts in enzymology Examples of drugs targeting different enzymes via different mechanisms Detailed discussion about many areas of enzymology such as binding and steady-state kinetics, assay development, and enzyme inhibition and activation Laboratory Guide to Enzymology is ideal for all pharmaceutical and biomedical researchers working in enzymology and assay development, as well as advanced students in the biochemical or biomedical sciences looking to develop a working knowledge of this field of research.
A Laboratory Guide to the Anatomy of The Rabbit: Second Edition
by Edward CraigieThe present work does not in any way aim to replace Bensley's Practical Anatomy of the Rabbit, which has long since proved its value beyond question. The attempt has been to meet a need for a shorter and less detailed laboratory guide adapted to courses for which Bensley's Anatomy has been found too extensive. Classes for which the present book is designed have assignments of time for this subject varying from about twenty-four hours to about sixty hours. Some of them have two-hour periods and some have three-hour periods. Some, moreover, have need for special emphasis on certain parts which are of less immediate interest to others. Of the twenty-eight illustrations, fifteen are new and the remainder have been borrowed from Bensley's Practical Anatomy. Four of the latter were the work of the late Dr. Bensley, the rest were prepared by the present author.
