چکیده پنبه (gossypium hirsutum l.) یکی از مهمترین محصولات در سراسر می باشد و جزء گیاهان متحمل به شوری طبقه بندی می شود. ارقام مختلف این گیاه نسبت به شوری خاک واکنش های متفاوت نشان می دهند. هدف از این تحقیق، اثر تنش شوری از نظر میزان تحمل ارقام پنبه از طریق سنجش فاکتورهایی نظیر آنتوسیانین ها، آنتی اکسیدانت ها، پرولین و برخی عناصر تحت اثر شوری های مختلف بود. بر این اساس 10 رقم پنبه شامل ساحل، q2...
یکی از محورهای برنامههای توسعه اقتصادی در ایران بعد از انقلاب، گرایش از برنامهریزی بخشی به سمت برنامهریزی منطقهای است و هدف این گرایش، تخصیص منابع و فعالیتها به هر نقطه بر مبنای استعدادها و ویژگیهای خاص آن منطقه و کاهش شکاف رشد اقتصادی بین مناطق مختلف کشور است. هدف این مطالعه نیز بررسی همگرایی رشد منطقه ای بخش کشاورزی استانهای ایران در بین سالهای 1380 تا 1390 میباشد. بر این اساس فرضیه ...
We report heterozygous, loss-of-function SOX2 mutations in three unrelated individuals with Anophthalmia-Esophageal-Genital (AEG) syndrome. One previously reported case [Rogers, R.C. (1988) Unknown cases. Proceedings of the Greenwood Genetic Center. 7, 57.] has a 2.7 Mb deletion encompassing SOX2 and associated with a cryptic translocation t(3;7)(q28;p21.3). The deletion and translocation break...
BACKGROUND Although the clinical outcome of patients with diffuse large B cell lymphoma (DLBCL) has been improved by the addition of rituximab to standard chemotherapy, almost one-third fails or relapses after first line treatment. The presence of monoclonal gammopathy (MG) is a known adverse prognostic factor for DLBCL. Because this subset of patients does not benefit from R-CHOP, new therapeu...
BackgroundWhile traditional pelvic exenterations (PE) represent a potentially curative treatment for recurrent tumours localized centrally in the pelvis, new surgical techniques have been developed recently to enable complete resection even invading into side wall. Extended (EPE) include of internal, external, or common iliac vessels, side-wall muscles, large nerves, bones. EPE are currently pe...
T-cell prolymphocytic leukaemia (T-PLL) is an aggressive T-cell neoplasm with a mature post-thymic T-cell phenotype. Most patients present with markedly elevated leucocyte counts, splenomegaly, lymphadenopathy, hepatomegaly, skin lesions, pleuroperitoneal effusions or central nervous system involvement (Matutes et al, 1991). The most frequent chromosome abnormalities in T-PLL are inv(14)(q11q32...
Despite the growing concern about actual on-going climate change, there is little consensus about the scale and timing of actions needed to stabilise the concentrations of greenhouse gases. Many countries are unwilling to implement effective mitigation strategies, at least in the short-term, and no agreement on an ambitious global stabilisation target has yet been reached. It is thus likely tha...
Motivated by the structure of existing pollution permit markets, we study the equilibrium path that results from allocating an initial stock of storable permits to an agent, or a group of agents, in a position to exercise market power. A large seller of permits exercises market power no differently than a large supplier of an exhaustible resource. However, whenever the large agent’s endowment f...
This paper analyzes the effects of pollution control regulation on input markets. Under Title IV of the 1990 Clean Air Act Amendments, sulfur dioxide emissions from large coal-fired electric power plants in the United States are regulated by a cap-and-trade system. We ask the question: Who captured the rents from Title IV? We first show that Phase I of the tradeable permits program, from 1995 t...
The human α1A voltage-dependent calcium channel (Cav2.1) is a pore-forming essential subunit embedded in the plasma membrane. Its cytoplasmic carboxyl(C)-tail contains a small poly-glutamine (Q) tract, whose length is normally 4∼19 Q, but when expanded up to 20∼33Q, the tract causes an autosomal-dominant neurodegenerative disorder, spinocerebellar ataxia type 6 (SCA6). A recent study has shown ...
