امروزه، آلودگی هوای کلان‌شهرها به یک چالش زیست‌محیطی اساسی تبدیل شده است. در مورد شهر تهران، که 90 درصد از وزن کل آلاینده‌های هوای آن از خودروها منتشر می‌شود، کربن منوکسید نسبت به بقیه آلاینده‌های هوا اهمیت بیشتری دارد، به‌طوری‌که بیش از 75 درصد وزن آلاینده‌های این شهر را دربر می‌گیرد. با توجه به اینکه تحلیل پایداری لایه سطحی جوّ، درحکم شاخص وضعیت تلاطمی آن، بیشترین اثر را در پراکنش آلاینده‌های ...

نیاز به پشتیبانی قدرتمند و پیشرفته پردازش اطلاعات (که از منابع مختلف تهیه شده اند) در برنامه­ ریزی ­ها (به دلیل حجم فرایند داده ­ها و رشد کاربر سامانه­ های (Systems) کارآ و قدرتمند پردازش اطلاعات را اجتناب­ ناپذیر می­ سازد، GIS یا سامانه اطلاعات جغرافیایی با ویژگی خاص تلفیق داده­ های مکانی و غیرمکانی در میان مدیران و برنامه­ ریزان، به عنوان یک سامانه از جایگاه خاصی برخوردار گردیده است.

Objective: Antiepileptic drugs (AEDs) that are usually used for treatment of epilepsy have substantial side effects and about 30% of patients continue to have seizures with current AEDs therapy. Some herbs which traditionally used in the management of seizures of many rural areas of the developing countries have shown anticonvulsant activity in modern pharmacological bioassays. The aim of the p...

Systemic mastocytosis (SM) is characterized by the abnormal proliferation and accumulation of mast cells (MCs). Constitutive activation of kit, a receptor tyrosine kinase (TK), has been associated with all types of SM. Signal transducers and activators of transcription (STATs), such as STAT5, mediate downstream kit signalling. We hypothesized that nuclear phospho-STAT5 (pSTAT5) in MCs might ref...

This paper applies the Model Confidence Set (MCS) procedure of Hansen, Lunde, and Nason (2003) to a set of volatility models. A MCS is analogous to confidence interval of a parameter in the sense that the former contains the best forecasting model with a certain probability. The key to the MCS is that it acknowledges the limitations of the information in the data. The empirical exercise is base...

The use of microcystins (MCs) contaminated water to irrigate crop plants represents a human health risk due to their bioaccumulation potential. In addition, MCs cause oxidative stress and negatively influence photosynthetic activities in plants. The present study was aimed at investigating the effect of MCs on photosynthetic parameters and antioxidative response of lettuce. Furthermore, the bio...

BACKGROUND Human mast cells (MCs) were classified into at least two subtypes, i.e., tryptase- and chymase-positive MCs (MC(TC)) and tryptase-only-positive MCs (MC(T)). However, differences in global molecular expression between these subtypes are unknown. METHODS We analyzed public microarray data of MC subtypes derived from various tissues and those of peripheral blood granulocytes by using ...

Aggregation of the high-affinity IgE receptor (FcεRI) on mast cells (MCs) causes MC degranulation, a process that involves cortical F-actin disassembly. Actin depolymerization may be triggered by increase of cytosolic Ca(2+). Entry of Ca(2+) through the Ca(2+) release-activated Ca(2+) (CRAC) channels is under powerful regulation by the serum- and glucocorticoid-inducible kinase SGK1. Moreover, ...

There’s a broad field of applications for the microcontroller technology, that can be enumerated from simple, like small electric equipment operation, until sophisticated, like single loop digital controllers with man-machine and machine-machine interface, also using complex digital control techniques. The main preoccupation for us is to transmit to an undergraduate student, who hadn’t had any ...

Exosomal miRNAs are emerging as mediators of the interaction between mast cells (MCs) and tumor cells. The exosomal miRNAs can be internalized by liver cancer cells to inhibit cell metastasis. We explored the interaction between MCs and hepatocellular carcinoma (HCC) cells. We used hepatitis C virus E2 envelope glycoprotein (HCV-E2) to stimulate MCs and harvest MCs-derived exosomes to detect th...
