BACKGROUND AND PURPOSE Increasing evidence suggests that iron deposition is present in the later stages of MS. In this study we examined abnormal phase values, indicative of increased iron content on SWI-filtered phase images of the SDGM in CIS patients and HC. We also examined the association of abnormal phase with conventional MR imaging outcomes at first clinical onset. MATERIALS AND METHO...
BACKGROUND The nature of bronchial mucosal inflammation and its physiologic and clinical significance in rhinovirus-induced asthma exacerbations is unclear. We investigated bronchial mucosal inflammatory response and its association with physiologic and clinical outcomes in an experimental model of rhinovirus-induced asthma exacerbations. METHODS We used immunohistochemistry methods to detect...
BACKGROUND This study compared the strength of incorporation and biocompatibility of 2 porcine-derived grafts (cross-linked and non-cross-linked) in a rat hernia model. METHODS A standardized 2 × 4 cm(2) fascial defect was created in 30 Wistar rats and repaired with either a cross-linked or a non-cross-linked graft. The rats were killed 3, 6, and 12 months later. The strength of incorporation...
Recently, we have described a panel of metastasis-associated antigens in the rat, i.e., of molecules expressed on metastasizing, but not on nonmetastasizing tumor lines. One of these molecules, recognized by the monoclonal antibody D6.1 and named accordingly D6. 1A, was found to be abundantly expressed predominantly on mesenchyme-derived cells. The DNA of the antigen has been isolated and clone...
LEP has proved to be one of the most flexible ee colliders built to date. It has operated at various energies, in several modes, with everincreasing demands for luminosity in clean and precisely known beam conditions. Together with some unique features, LEP therefore has much in common with future ee factories. Beam-dynamical phenomena have been among the crucial determinants of LEP’s performan...
به منظور بررسی اثر اسید هیومیک بر صفات مورفولوژیک و عملکرد گل زعفران، آزمایشی در سال 1395- 1394 در قالب طرح بلوکهای کامل تصادفی در دانشکده کشاورزی دانشگاه بیرجند اجرا شد. تیمارهای آزمایش شامل چهار سطح اسید هیومیک (0، 5، 10 و 15 لیتر در هکتار) با سه تکرار بود. نتایج نشان داد، اسید هیومیک تاثیر معنیداری بر اجزا برگ (وزن تر و خشک و کلروفیل a )داشت، به طوریکه، بیشترین وزن تر برگ (0/116 گرم در بوت...
