Mast cells (MCS) are not simple trouble makers in immediate allergic hypersensitivity, but play various important biological roles in host defense as well as tissue remodeling after infl ammation such as wound healing and fi brosis. Since heterogeneity exists in human MCS, human skin type MCS should be used for dermatological research. A large number of pure human skin type MCS which satisfy al...
Background Neurofibroma consists of abundant extracellular matrix and many types of cells, including Schwann cells (SCs), mast cells (MCs), fibroblasts and endothelial cells. As SCs have been found to be the cell of origin for neurofibroma, how MCs may migrate into the tumor has not been fully clarified. Given that chemokine receptor CCR3 is found predominantly expressed by differentiated MCs, ...
The differentiation of the vegetative or unresponsive wakefulness syndrome (VS/UWS) from the minimally conscious state (MCS) is an important clinical issue. The cerebral metabolic rate of glucose (CMRglc) declines when consciousness is lost, and may reveal the residual cognitive function of these patients. However, no quantitative comparisons of cerebral glucose metabolism in VS/UWS and MCS hav...
Mast cells (MCs) have been identified in various tumors; however, the role of these cells in tumorigenesis remains controversial. Here, we quantified MCs in human and murine malignant pleural effusions (MPEs) and evaluated the fate and function of these cells in MPE development. Evaluation of murine MPE-competent lung and colon adenocarcinomas revealed that these tumors actively attract and sub...
OBJECTIVE To establish consensus recommendations among health care specialties for defining and establishing diagnostic criteria for the minimally conscious state (MCS). BACKGROUND There is a subgroup of patients with severe alteration in consciousness who do not meet diagnostic criteria for coma or the vegetative state (VS). These patients demonstrate inconsistent but discernible evidence of...
The advantage of Monte Carlo simulations is attributed to the flexibility of their implementation. In spite of their prevalence in finance, we address their efficiency and accuracy in option pricing from the perspective of variance reduction and price convergence. We demonstrate that increasing the number of paths in simulations will increase computational efficiency. Moreover, using a t-test, ...
We study the problem of minimal triangulation of graphs. One of the first algorithms to solve this problem was Lex M, which was presented in 1976. A new algorithm, and a simplification of Lex M called MCS-M, was presented in 2002. In this paper we compare these two algorithms and show that they produce the same set of triangulations, answering an open question mentioned by the authors of MCS-M.
هدف: هدف پژوهش حاضر، ساخت و اعتبارسنجی سیاهه آسیب‌شناسی روانشناختی نوجوانان در فضای مجازی بود. روش: روش آمیخته اکتشافی (کیفی-کمی) بدین منظور با استفاده از تحلیل مضمون مقالات مصاحبه‌های انجام‌شده متخصصان فعال مجازی، آسیب ها شناسایی شدند بر اساس آن ای ساخته شد. جامعه آماری بخش کیفی شامل مقالات، اساتید دانشگاه های اراک، اصفهان، امام خمینی قزوین شهر اراک بودند که نمونه هدفمند آنها انتخاب کمی بو...
طیف توان ساختارهای یزرگ مقیاس به عنوان معیاری از دامنه و رشد افت و خیزها در دورانهای مختلف، کلیدی اساسی برای کاوشهای کیهان شناسی مربوط به چگونگی شکل گیری و تحول ساختارهای یزرگ مقیاس می باشد. یک روش مفید و قدرتمند برای انجام چنین تحقیقی استفاده از ویژگی های خطوط جذبی لیمان آلفا می باشد. این خطوط جذبی که بر اثر گذار الکترون از تراز 1 به تراز 2 اتمهای هیدروژن خنثی واقع در فضای میان کهکشانی تولید م...
The relationship between mast cells (MCs) and pregnancy is a controversially discussed topic. The presence and quantitative distribution of MCs in the reproductive tract was confirmed in different species. A phase-dependent oscillation of MCs during the hormonal regulated estrous cycle was suggested and on this basis, MCs were assumed to play a positive role in implantation because of their abi...
