Veterinary Embryology - PDF
نویسندگان: خلاصه: A thorough appreciation of the cellular, molecular and tissue changes which precede the birth of an animal is a fundamental requirement for understanding normal structural development and also abnormal processes which result in congenital defects. This textbook provides information relevant to many subjects taught in preclinical, paraclinical and clinical years. Early chapters describe and explain sequential events relating to the division, growth and differentiation of cells and to the formation of foetal membranes, implantation and placentation. Succeeding chapters trace the origin, growth, development and maturation of the major body systems. Age determination of the embryo and foetus is reviewed in a single chapter. Genetic, chromosomal and environmental factors which adversely affect pre-natal development are reviewed in the final chapter. A reading list at the end of each chapter offers additional sources of information on the topics discussed. Tables, flow diagrams and numerous hand-drawn illustrations provide information in a form which complements the concepts presented in the text.

Principles of Tissue Engineering Fifth Edition - Original PDF
نویسندگان: خلاصه: Now in its fifth edition, Principles of Tissue Engineering has been the definite resource in the field of tissue engineering for more than a decade. The fifth edition provides an update on this rapidly progressing field, combining the prerequisites for a general understanding of tissue growth and development, the tools and theoretical information needed to design tissues and organs, as well as a presentation by the world’s experts of what is currently known about each specific organ system. As in previous editions, this book creates a comprehensive work that strikes a balance among the diversity of subjects that are related to tissue engineering, including biology, chemistry, material science, and engineering, among others, while also emphasizing those research areas that are likely to be of clinical value in the future. This edition includes greatly expanded focus on stem cells, including induced pluripotent stem (iPS) cells, stem cell niches, and blood components from stem cells. This research has already produced applications in disease modeling, toxicity testing, drug development, and clinical therapies. This up-to-date coverage of stem cell biology and the application of tissue-engineering techniques for food production – is complemented by a series of new and updated chapters on recent clinical experience in applying tissue engineering, as well as a new section on the emerging technologies in the field.
Direct Microscopic Somatic Cell Count - Original PDF
نویسندگان: خلاصه: The direct microscopic somatic cell count (DMSCC) is microscopic count of the actual number of somatic cells in milk. A somatic cell is any biological cell forming the body of an organism. In dairy industry, the somatic cell count (SCC) is an indicator of the safety and quality of milk. Mastitis is an inflammation of the udder typically associated with microbial infection. The number of somatic cells increases in response to presence of pathogenic bacteria like Staphylococcus aureus, a cause of mastitis. Somatic cells (SC) are cells from the cow (predominantly white blood cells, otherwise known as leukocytes) that are normally present in milk. During most mastitis infections, the number of leukocytes present in the udder increases to help the cow, goat, ewe, camel, buffalo etc. to fight the infection. The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 SC in ml for uninfected cows and greater than 250,000 SC in ml for cows infected with significant pathogen levels. There are several indirect and direct laboratory methods used for determination of somatic cells count in milk. Routine instrumental laboratory methods like flow cytometry have to be regularly calibrated using reference materials with a known concentration of somatic cells. The concentration of somatic cell count can be determined by reference microscopic method. The first microscopic procedure for examination of milk films was described in 1910 by Prescott and Breed. Staining of somatic cells was later modified by Newman, Lampert, Levowitz, Weber and other researchers. This microscopic method was processed into a normative form by the International Dairy Federation and later by International Standard Organisation. There are several possibilities to stain somatic cells. Somatic cells can be stained by dipping the dried smear on the slide in the modified Newman-Lampert methylene blue stain solution (cow’s milk and ewe’s milk) or methyl green-pyronin Y stain solution (goat’s milk) or by mixing the milk in reagent tube with ethidium bromide stain solution (milk from all species). Subsequently, the microscopic slide with fixed smear and stained cells is examined using a microscope or epifluorescence microscope with immersion oil objective at magnification 500× to 1000×. Somatic cells are counted in several microscopic fields. Consequently, the somatic cells count is calculated using one of several mathematical formulas listed in international standard. The direct microscopic somatic cell count method is suitable for precise laboratory analysis of somatic cell in raw milk. However, this microscopic method has some limitations that may influence the results of analysis. This book contains the theoretical and practical information about this laboratory method.
Separation: Anxiety and Anger - Original PDF
نویسندگان: خلاصه: Dr. Bowlby's second pioneering volume examines the effect of separation on the development of the child and the psychopathology that often follows separation. The experience of separation and the ensuing susceptibility to anxiety, anger, and fear constitute the flip side of the attachment phenomenon. In an authoritative new foreword to Bowlby's classic study, Stephen Mitchell (who gives resonant voice to the relational perspective in psychoanalysis) bridges the distance between attachment theory and the psychoanalytic tradition.
Loss: Sadness and Depression - Original PDF
نویسندگان: خلاصه: In this third and final volume John Bowlby completes the trilogy Attachment anf Loss, his much acclaimed work on the importance of the parental relationship to mental health. Here he examines the ways in which young children respond to a temporary of permenant loss of a mother-figure and the expression of anxiety, grief and mourning which accompany such loss. The theories presented differ in many ways from those advanced by Freud and elaborated by his followers, so much so that the frame of reference now offered for understanding personality developement and psychopathology amounts to a new paradigm.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
