Las experiencias relatadas sobre los meses de confinamiento, reunidas en este libro, serán comprensibles para todo aquel que ha vivido las circunstancias de esta pandemia global. Se trata de una marca muy profunda que hemos recibido de manera colectiva y, por lo tanto, las lectoras y lectores de este libro serán capaces de sentirse cómplices de estos relatos.
Most of the matter in our solar system, and, probably, within the whole universe, exists in the form of ionized particles. On the other hand, in our natural environ ment, gaseous matter generally consists of neutral atoms and molecules. Only under certain conditions, such as within the path oflightning or in several technical devices (e. g. gas discharges, rocket engines, etc. ) will some of the atoms and molecules be ionized. It is also believed that the chemistry of the earth's troposphere predomi nantly proceeds via reactions between neutral particles. (The complex system of atmospheric chemistry will be treated in one of the forthcoming volumes to this series. ) Why, then, are ions consi...
This issue of Clinics in Geriatric Medicine is devoted to Geriatric Urology. Guest Editor Tomas L. Griebling, MD, MPH has assembled a group of expert authors to review the following topics: Non-Surgical Treatment of Urinary Incontinence in Elderly Women; Outcomes of Surgery for Stress Urinary Incontinence in Older Women; Evaluation and Management of Pelvic Organ Prolapse in Elderly Women; Underactive Bladder in Older Adults; Translational Research and Voiding Dysfunction in Older Adults; Functional Brain Imaging and Voiding Dysfunction in Older Adults; The Role of Urodynamics in Elderly Patients; Associations Between Voiding Symptoms and Sexual Health in Older Adults; Asymptomatic Bacteriuria and Urinary Tract Infections in Older Adults; Comorbidity and Surgical Risk in Older Urologic Patients; Small Renal Masses in Older Adults; Prostate Cancer in Elderly Men: Active Surveillance and Other Considerations; Late Onset Hypogonadism and Testosterone Replacement in Elderly Men; and Contemporary Chemotherapy for Urologic Malignancies in Geriatric Patients.
This work begins with a boy named Geraldo growing up Sicilian in Rochester, New York, and ends with the author breakfasting with Eleanor Roosevelt in the White House. It is a portrait of what it was like to come of age in the 1930s and 1940s.
This book is the first of its kind entirely dedicated to carbohydrate vaccines written by renowned scientists with expertise in carbohydrate chemistry and immunochemistry. It covers the synthesis of carbohydrate antigens related to bacteria and parasites such as: Heamophilus influenza, Streptococcus pnemoniae, Shigella flexneri, Candida albicans, Mycobacterium tuberculosis, and Chlamydia. The first three chapters are of wide interest as they cover fundamental concerns in new vaccine developments. The first one presents the immune system and how carbohydrate antigens are processed before protective antibodies are produced. It also illustrates antigen presentation in the context of major histo...
Reviews the use of synthetic oligosaccharides in biochemistry, immunology, pharmaceutical and medicinal chemistry. Presents strategies for synthesis of complex oligosaccharides. Discusses the mechanisms of interaction between carbohydrates and biologically important proteins, such as enzymes, immunoglobulins, and receptor proteins. Valuable reading for biochemists, immunologists, pharmaceutical chemists, organic synthetic chemists, pharmacologists, and researchers in the life sciences.
This expansive and practical textbook contains organic chemistry experiments for teaching in the laboratory at the undergraduate level covering a range of functional group transformations and key organic reactions.The editorial team have collected contributions from around the world and standardized them for publication. Each experiment will explore a modern chemistry scenario, such as: sustainable chemistry; application in the pharmaceutical industry; catalysis and material sciences, to name a few. All the experiments will be complemented with a set of questions to challenge the students and a section for the instructors, concerning the results obtained and advice on getting the best outcome from the experiment. A section covering practical aspects with tips and advice for the instructors, together with the results obtained in the laboratory by students, has been compiled for each experiment. Targeted at professors and lecturers in chemistry, this useful text will provide up to date experiments putting the science into context for the students.
Protein kinases are fascinating enzymes that maintain the proper function of nearly every task performed by the cells of the human body. By extracting a phosphate from the energy molecule ATP and linking it to another protein, protein kinases alter the structure and ultimate function of other proteins. In this way, protein kinases help monitor the extracellular environment and integrate signaling cues that, for the most part, are beneficial for human health and survival. However, protein kinases are often dysregulated and responsible for the initiation and progression of many types of cancers, inflammatory disorders, and other diseases. Thus, decades of research have revealed much about how ...
"Brings kids inside the world of music by helping them understand what proficient listeners think and feel as they listen to music, and what musicians think and feel as they play music ... Students construct their own understandings of music, first through an exploration of their personal relationship to music, then through a series of listen and talk sessions, and finally, by composing their own pieces and exploring the connections between their lives and the works of music they create ... All lessons fulfill the National Standards for Music Education"--From publisher description.
