PURPOSE Our aim was to investigate the distribution of CD34 and smooth muscle cell actin positive myofibroblasts in the stroma of the normal mammary gland, benign and malignant tumors. The observations were especially focused on the diagnostic value of the cumulative results obtained with these immunoreactions. METHODS Our study included 112 female patients with suspect breast masses obtained...
The right inferior frontal gyrus (rIFG) and the presupplementary motor area (pre-SMA) have been identified with cognitive control-the top-down influence on other brain areas when nonroutine behavior is required. It has been argued that they "inhibit" habitual motor responses when environmental changes mean a different response should be made. However, whether such "inhibition" can be equated wi...
Shape memory alloy (SMA) thin films formed by sputter deposition have attracted considerable attention in the last decade. Current intensive research demonstrated that thin films' unique fine microstructure is responsible for superior shape memory characteristics in films, compared to that of bulk materials. Simultaneously, much effort has been taken in the development and fabrication of microd...
Background Tuberous Sclerosis Complex (TSC), and Spinal Muscular Atrophy (SMA) are two inherited disorders while they are genetically independent. TSC is characterized by the formation of multiple hamartomas in nearly all organs. SMA is a destructive neurological disorder leading to progressive muscular weakness and atrophy. Case Presentation</e...
it is several decades that the application of membrane processes for gas separation has become a great concern within industries. among them, the polymeric membranes of different structures have played the most important role. such application has been widely extended to gas separation and due to the necessity of both; prediction of the behavior of these processes and recognition of the effecti...

This paper proposes a re-centering variable friction device (RVFD) for control of civil structures subjected to near-field earthquakes. The proposed hybrid device has two subcomponents. The first subcomponent of this hybrid device consists of shape memory alloy (SMA) wires that exhibit a unique hysteretic behavior and full recovery following post-transformation deformations. The second subcompo...
به طور کلی در فرآیندهای مارکوف ارگودیک دو بعدی یافتن فرم بسته توزیع ایستا، تنها برای حالات خیلی خاص امکان پذیر است. با توجه به این مشکل و نیز با توجه به اهمیت توزیع ایستا، بررسی و مطالعه رفتار مجانبی توزیع ایستای این فرآیندها مورد توجه قرار گرفته است. زنجیر قدم زدن تصادفی دو بعدی که در برخی متون به آن، فرآیند qbd دو طرفه نیز می گویند، یکی از این فرآیندها است. یک فرآیند qbd زمان گسسته یک زنجیر م...
Background & Aims: Spinal muscular atrophy (SMA) is a common disorder with autosomal recessive inheritance pattern. The frequency of carriers of this disease is one in forty to one in sixty. SMA occurs in 98% of cases due to the homozygous deletion of SMN1 exons 7 and 8. The purpose of this study was to evaluating the deletion and point mutations of the SMN1 gene in patients with SMA in west Az...
Background: Spinal muscular atrophy includes a group of neuromuscular disorders characterized by degeneration of anterior horn cells in the spinal cord, and leads to progressive muscular weakness. NAIP is one of the genes that inhibits motor neuron apoptosis. Deletion of this gene is usually observed in type I SMI. The aim of this study was to investigate the frequency and pathogenicity of NAIP...
