Download or read book Junctional Complexes of Epithelial Cells written by Gregory R. Bock and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epithelial cells cover the outer and inner surfaces of the body, forming a selective polarized barrier between the intercellualar space and the 'external' world. Linking the cells of this continuous layer and contributing to epithelial organization and function are specialized membrane domains--desmosomes, gap junctions, and occluding junctions. The contributors to this multidisciplinary symposium volume explore the nature of such junctional structures, focusing on the molecular organization and diversity of their constituent proteins, their formation and control, and interactions with ions and cytoskeletal elements. The physiological significance of cell-cell interaction in epithelia is considered, with reference to cell adhesion, barrier formation and intercellular communication, and to the functional implications for tissue architecture, embryonic development, morphogenesis and carcinogenesis.

Download or read book Tight Junctions in Cancer Metastasis written by Tracey A. Martin and published by Springer Science & Business Media. This book was released on 2013-02-26 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a dramatic increase in knowledge of tight junctions in the past decade. The molecular structure of tight junctions, cellular functions and the pathophysiological roles of tight junctions are becoming clear. Of the most important functions, the role of the cellular structure in cancer spread and drug delivery are increasingly realised. It is now clear that there are fundamental changes to tight junctions during the process of cancer development. Tight junctions are also critical to the metastatic process of cancer cells. The cellular structure is also crucial in drug therapies, namely, the permeability and bioavailability of the drugs, penetration of barriers such as the blood brain barrier. This current volume aims to summarise the current knowledge of tight junctions, their role in cancer and cancer metastasis and is of interest to scientists and clinicians.

Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Download or read book Biology and Regulation of Blood Tissue Barriers written by C. Yan Cheng and published by Springer Science & Business Media. This book was released on 2014-01-25 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written by many outstanding investigators who have spent decades to study different aspects of blood‐tissue barrier function. They have summarized some of the latest and fascinating development in their fields of research including the blood‐brain barrier, the blood‐retinal barrier, the gut barrier, the blood‐biliary barrier, the blood‐follicle barrier, the blood‐epididymis barrier, the blood‐testis barrier, the tight junction barrier in general as well as barriers in the female reproductive tract. Included are also chapters that focus on topics that are physiologically applicable to all blood‐tissue barriers. Many of these chapters also include information on specific human diseases, such as pathological changes of the gut barrier that cause bowel disorders resulting from inflammation of the epithelial lining in the intestine, and infertility in men as a result of disruption of the blood‐epididymal and/or blood‐testis barriers; and on new therapeutic approaches (e.g., drug delivery across the blood‐brain and the blood‐retinal barriers).
Download or read book ART and the Human Blastocyst written by David K. Gardner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of human artificial reproductive technology (ART) is continually advancing and has witnessed significant changes since the inception of Louise Brown in 1978. Though Louise Brown herself was conceived after the trans fer of a blastocyst, there remain significant confusion and debate regarding the stage at which the human embryo conceived in the laboratory should be replaced in the mother. Developments in culture media formulations, leading to the introduction of sequential media, have brought the role of the blasto cyst in human ART back into the spotlight. It was due to this resurgence of interest in the niche of extended culture in human infertility treatment that the symposium on "ART and the Human Blastocyst" was held. of this meeting within this volume bring to the forefront The proceedings the main issues raised with the transfer of embryos at the blastocyst stage. It is evident from the chapters that follow that ART needs to be perceived as a continuum of procedures, each one dependent on the preceding one, and all equally as important as each other. That is to say, the development of a com petent embryo is ultimately dependent on the quality of the gametes from which it was derived. With regard to the oocyte, this then places the emphasis on the physician to use a stimulation protocol that both produces quality oocytes and does not impair endometrial function. Maintenance of gamete and embryo quality is the laboratory's role.

Download or read book Cells Molecules and Mechanisms written by Eric Wong and published by Axolotl Academic Publishing. This book was released on 2009 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Yet another cell and molecular biology book? At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology."--Open Textbook Library.
Download or read book Cell cell Junctions written by Alpha S. Yap and published by Perspectives Cshl. This book was released on 2017 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neighboring cells are linked to each other by multimolecular complexes such as adherens junctions, desmosomes, and gap junctions. These complexes help maintain tissue integrity, act as barriers to permeability, reinforce cell polarity, and allow cells to communicate with each other. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology reviews our understanding of the organization, regulation, and dynamics of cell-cell junctions and the roles they play in morphogenesis, tissue homeostasis, and disease. The contributors examine the assembly and structure of different cell-cell adhesion systems, the plasticity of cell-cell junctions (e.g., during cell migration), and how the junctions act as hubs to sense and transduce various mechanical and chemical signals. The authors also discuss the roles of cell-cell junctions in specific developmental and physiological processes, such as hearing, skeletal myogenesis, and neural circuit assembly, as well as in diseases such as cancer. This volume is therefore an indispensable reference for cell and developmental biologists, as well as anyone interested in understanding the roles of these complexes in human health and disease.
