Permanganate—A New Fixative for Electron Microscopy
During the early phases of tissue sectioning for electron microscopy, virtually all of the standard cytological fixatives were tried. Of these, osmium tetroxide appeared to give the best preservation, and this was further improved by buffering the fixative solution at a slightly alkaline pH (Palade (1)). A variant developed by Dalton (2) contains Os04 in a chromate-dichromate system. Formalin h...

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولMultiparameter immunofluorescence on paraffin-embedded tissue sections.
Immunohistochemical techniques have gained increasing importance in diagnostics and research. While formalin-fixed, paraffin-embedded human tissue retains excellent morphology, the detection of antigens by immunofluorescence in its sections and especially the demonstration of multiple simultaneous antibodies have limitations. Double immunofluorescence labeling of routinely processed paraffin se...
متن کاملRCL2, a new fixative, preserves morphology and nucleic acid integrity in paraffin-embedded breast carcinoma and microdissected breast tumor cells.
Methacarn and RCL2, a new noncrosslinking fixative, were compared to formalin-fixed or frozen tissue samples of the same invasive breast carcinoma and were evaluated for their effects on tissue morphology and immunohistochemistry as well as DNA and RNA integrity. The histomorphology of methacarn- or RCL2-fixed paraffin-embedded tumors was similar to that observed with the matched formalin-fixed...
متن کاملStorage of Frozen Sections in Paraffin Blocks.
The development of the techniques for cutting frozen sections, in particular the use of cryostat microtomes (Pearse, 1960; Cunningham, Bitensky, Chayen, and Silcox, 1960 and 1962; Goodbody, 1963 a and b; Cunningham, 1963), has resulted in sections which not only are produced routinely very rapidly but which are completely acceptable histologically. Such sections would be ideal, especially where...
