توضیحاتی در مورد کتاب :
درک گسترده ای از نقشی که کلسیم در فیزیولوژی سلولی و فیزیولوژی پاتو ایفا می کند به دلیل مطالعات پیشگامانه بسیاری از دانشمندانی که در هفتمین سمپوزیوم بین المللی بهاری علوم بهداشتی در دانشگاه جورج واشنگتن در واشنگتن دی سی شرکت کردند، به دست آمده است. شرکت کنندگان در این نشست منحصر به فرد از زمینه های مختلف تحقیقات پایه و بالینی مانند فیزیولوژی مولکولی، انکولوژی، ژنتیک مولکولی، قلب و عروق، انرژی زیستی، آسیب شناسی، و غدد درون ریز رنجیدند. محتوای مقالات سمپوزیوم نشاندهنده کار در این حوزهها و سایر حوزههای تحقیقات زیستپزشکی است. هدف سازماندهی این کتاب ایجاد تعادل بین بیوشیمی 2 و فیزیولوژی متابولیسم سلولی طبیعی + کلسیم و پیامدهای پاتولوژیک تغییرات آل 2 در هموستاز کلسیم + سلول است. بخش اول کتاب به مکانیسمهای انتقال مسئول تنظیم 22 کلسیم داخل سلولی و روشهای دارویی برای کنترل کلسیم سلولی اختصاص دارد. توجه ویژه ای به اساس مولکولی برای فعالیت های حمل و نقل غشای پلاسما، 2 2 از جمله پمپ Ca + ATP، سیستم تبادل Na + -Ca + و کانال های 2 Ca + حساس به ولتاژ داده شده است. بخش دوم روابط هیجان انگیز بین اولیسم phosphoinositide metab 2، انتقال سیگنال، و متابولیسم Ca + سلول را پوشش می دهد. این بخش با مروری شیوا توسط پروفسور مایکل بریج، که سخنران اصلی سمپوزیوم و دریافت کننده جایزه شایستگی علمی بود، آغاز می شود.

توضیحاتی در مورد کتاب به زبان اصلی :
A widespread appreciation for the role that calcium plays in cell physiology and patho physiology has now been achieved due to the pioneering studies of many of the scientists who attended the VIIth International Spring Symposium on Health Sciences at George Washington University in Washington, D. C. The participants in this unique meeting rep resented diverse fields of basic and clinical research, such as molecular physiology, oncology, molecular genetics, cardiology, bioenergetics, pathology, and endocrinology. The content of the proceedings of the symposium represents work in these and other areas of biomedical research. Organization of the book is aimed at striking a balance between the biochemistry 2 and physiology of normal cell Ca + metabolism and the pathological consequences of al 2 terations in cell Ca + homeostasis. The first section of the book is devoted to the transport mechanisms responsible for 2 2 regulating intracellular Ca + and the pharmacological modalities for controlling cell Ca + . Particular attention is given to the molecular basis for plasma membrane transport activities, 2 2 including the ATP-driven Ca + pump, the Na + -Ca + exchange system, and voltage sensitive 2 Ca + channels. The second section covers the exciting relationships between phosphoinositide metab 2 olism, signal transduction, and cell Ca + metabolism. This section begins with an eloquent overview by Professor Michael Berridge, who was the keynote speaker at the symposium and the recipient of the scientific merit award.
