Frozen Thin Sections of Fresh Tissue for Electron Microscopy, with a Description of Pancreas and Liver
A simple method has been developed that allows frozen thin sections of fresh-frozen tissue to be cut on a virtually unmodified ultramicrotome kept at room temperature. A bowl-shaped Dewar flask with a knifeholder in its depths replaces the stage of the microtome; a bar extends down into the bowl from the microtome's cutting arm and bears the frozen tissue near its lower end. When the microtome ...
متن کاملTemperature quantitation and mapping of frozen tissue.
A method was developed for quantitating the temperature within frozen tissue with the magnetic resonance (MR) parameter R2*. The pulse sequence uses half-pulse excitation and a short spiral readout to achieve echo times as short as 0.2 msec. Fiber-optic temperature sensors were inserted into bovine liver tissue. The tissue was frozen at one end while being held warm at the other end. Once stead...
متن کاملFast and Simple Protocols for Mass Spectrometry-Based Proteomics of Small Fresh Frozen Uterine Tissue Sections
Human tissues are an important link between organ-specific spatial molecular information, patient pathology, and patient treatment options. However, patient tissues are uniquely obtained by time and location, and limited in their availability and size. Currently, little knowledge exists about appropriate and simplified protocols for routine MS-based analysis of the various types and sizes of ti...
متن کاملAccuracy of Frozen Sections
Background and Objective: Intraoperative consultation by frozen section is a high – risk procedure with important consequences. Therefore, it is critical to determine efficiency of frozen section performance periodically. This study was performed to determine the accuracy of frozen section in Urmia University of Medical Sciences. Materials & Methods:Inthis cross sectional study, we compared th...
متن کاملUltrastructure of the adrenal cortex in frozen thin sections.
Pieces of both unfixed and fixed rat adrenal cortex were frozen and cut with a cryoultramicrotome. In unstained frozen sections of unfixed adrenals patches of heterochromatin were seen in the nucleus, while numerous round uniformly dense structures, the mitochondria, could be identified in the cytoplasm. Lipid droplets appear as small ligh round areas. Staining the sections with potassium perma...
