— Clearing was an important step in the preparation of histological sections aiming to remove alcohol and other dehydrating agents from tissues prior to infiltration of the paraffin wax Xylene
Yêu cầu trực tuyến →In addition tissue scraped off FFPE slides or from scrolls of FFPE tissue may be used for molecular or proteomic analyses Hematoxylin and eosin staining of FFPE sections reviewed by a pathologist are highly valuable to ensure the presence of adequate lesional cells for molecular and other analyses Therefore proper microtomy technique is
Yêu cầu trực tuyến →2 — Paraffin sections are usually cut at a thickness of 3 5µm ensuring that only a single layer of cells makes up the section a red blood cell has a diameter of about 7µm One of the advantages of paraffin wax as an embedding agent is that as sections are cut they will stick together edge to edge forming a ribbon of sections
Yêu cầu trực tuyến →— Adapted from lithotripsy technology used for treatment of ureterorenal calculi intravascular lithotripsy IVL is a novel technique for the treatment of severely calcific plaque lesions that uses acoustic shockwaves in a balloon based delivery system Shockwaves induce calcium fractures which facilitate stent expansion and luminal gain
2 — For example tissue components must retain some chemical reactivity so that specific staining techniques can be applied subsequently 3 Formalin usually as a phosphate buffered solution is the most popular fixative for preserving tissues that will be processed to prepare paraffin sections Ideally specimens should remain in fixative for
Yêu cầu trực tuyến →This protocol was adapted from Preparation of Cells and Tissues for Fluorescence Microscopy Chapter 4 in Basic Methods in Microscopy This protocol describes the sectioning of tissues embedded in paraffin blocks Paraffin sections require extensive fixation and processing steps but provide superior morphology compared with other
Yêu cầu trực tuyến →— FFPE involves the process of dehydrating and the infiltration of paraffin into the tissue This tissue is then encased in paraffin to create the tissue block and thin sections are sliced with a microtome Paraffin sections are more physically stable than frozen sections and better at preserving tissue morphology with less injury

— Paraffin wax 58 60 ºC two changes 2 hours each; Embedding tissues into paraffin blocks Trim paraffin blocks as necessary and cut at 3 10 um 5 um is commonly used Place paraffin ribbon in water bath at about 40 45 ºC Mount sections onto slides Allow sections to air dry for 30 minutes and then bake in 45 50 ºC oven overnight
Yêu cầu trực tuyến →— The Holmium Ho YAG laser is presently the most extensively employed in laser lithotripsy for the management of kidney stones Despite its adoption as the gold standard for laser lithotripsy Ho YAG laser lithotripsy poses three significant challenges namely thermal effect insufficient stone fragmentation and stone displacement which
Yêu cầu trực tuyến →— Sections cut to a thickness of 2 µm with a single tissue section on each slide were employed in this study since this is our laboratory standard In a previous study Yörükoglu et al 6 employed a wash in warm buffer to prevent the sections to be smeared with liquid paraffin after combined HIER and dewaxing In our study we did not observe
— Tissue embedding and sectioning is a backbone of many biological research labs While commiserating with other grad students over tedious hours spent in the lab you re probably aware that there is more than one way to slice up a chunk of ve previously introduced what to consider when choosing a tissue embedding
Yêu cầu trực tuyến →— Heat sections at 56°C for 30 minutes to affix sections well Most tissue sections will bind well under these conditions If there is a problem with section adhesion heating the sections for up to 24 hours at 56°C or for 1 hour at 75°C will increase adhesion
Yêu cầu trực tuyến →— we show you how to perform IHC using paraffin embedded sections Typically these will be formalin fixed paraffin embedded FFPE section Unlike using a cryostat on frozen section paraffin embedded sections can sometimes better preserve tissue morphology Paraffin sections also let you work with larger tissues and storage is
Yêu cầu trực tuyến →Lithotripsy is a procedure used to treat kidney stones that are too large to pass through the urinary tract It works by sending focused ultrasound energy or shock waves directly to the stone The shock waves break a large stone into smaller stones that will pass through the urinary system Lithotripsy lets people with certain types of kidney stones avoid surgery
