Microtome: A microtome (from the Greek mikros, meaning "small", and temnein, meaning "to cut") is a tool used to cut extremely thin slices of material, known as sections. Important in science, microtomes are used in microscopy, allowing for the preparation of samples for observation under transmitted light or electron radiation.Intraoperative radiation therapySurgical pathology: 200px|right|thumb|[[Malignant melanoma of the skin. This is as it would appear on the patient.Lower segment Caesarean section: A lower (uterine) segment Caesarean section (LSCS) is the most commonly used type of Caesarean section used today. It includes a transverse cut just above the edge of the bladder and results in less blood loss and is easier to repair than other types of Caesarean sections.Henry Wurtz: Henry Wurtz (5 June 1828 in Easton, Pennsylvania – 1910) was an American chemist. He graduated from Princeton in 1848, and then studied chemistry at the Lawrence Scientific School of Harvard.Telepathology: Telepathology is the practice of pathology at a distance. It uses telecommunications technology to facilitate the transfer of image-rich pathology data between distant locations for the purposes of diagnosis, education, and research.Immunoperoxidase: Immunoperoxidase is a type of immunostain used in molecular biology, medical research, and clinical diagnostics. In particular, immunoperoxidase reactions refer to a sub-class of immunohistochemical or immunocytochemical procedures in which the antibodies are visualized via a peroxidase-catalyzed reaction.Vital stain: A vital stain in a casual usage may mean a stain that can be applied on living cells without killing them. Vital stains have been useful for diagnostic and surgical techniques in a variety of medical specialties.Male breast cancerTARGIT: TARGIT (TARGeted Intra-operative radioTherapy) is a technique of giving radiotherapy to the tissues surrounding a cancer after its surgical removal. The technique was designed in 1998 at the University College London.Microspherophakia: Microspherophakia is a rare congenital autosomal recessive condition where the lens of the eye is smaller than normal and spherically shaped. This condition may be associated with a number of disorders including Peter's anomaly, Marfan syndrome, and Weill–Marchesani syndrome.Prescription cascade: Prescription cascade refers to the process whereby the side effects of drugs are misdiagnosed as symptoms of another problem resulting in further prescriptions and further side effects and unanticipated drug interactions. This may lead to further misdiagnoses and further symptoms.Assay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Inferior mesenteric lymph nodes: The inferior mesenteric lymph nodes consist of:Monoclonal antibody therapyBrain biopsyLow-voltage electron microscope: Low-voltage electron microscope (LVEM) is an electron microscope which operates at accelerating voltages of a few kiloelectronvolts or less. While the low voltage electron microscopy technique will never replace conventional high voltage electron microscopes, it is quickly becoming appreciated for many different disciplines.Toluidine blue stainLiquid nitrogen vehicle: A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor.Breast biopsyFixative (drawing): In drawing, a fixative is a liquid, similar to varnish, which is usually sprayed over a finished piece of artwork, usually a dry media artwork, to better preserve it and prevent smudging.Dermatology: Dermatology is the branch of medicine dealing with the skin, nails, hair and its diseases.Random House Webster's Unabridged Dictionary.Breast cancer classification: Breast cancer classification divides breast cancer into categories according to different schemes, each based on different criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes.Invasive lobular carcinomaLymphovascular invasionDinitrogen tetroxideKeratin 6A: Keratin 6A is one of the 27 different type II keratins expressed in humans. Keratin 6A was the first type II keratin sequence determined.Anaplastic carcinoma: Anaplastic carcinoma is a general term for a malignant neoplasm arising from the uncontrolled proliferation of transformed cells of epithelial origin, or showing some epithelial characteristics, but that reveal no cytological or architectural features of associated with more differentiated tumors, such as the glandular formation or special cellular junctions that typical of adenocarcinoma and squamous cell carcinoma, respectively.Hysterectomy Educational Resources and Services (HERS) FoundationStratified squamous epithelium: A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.Autoradiograph: An autoradiograph is an image on an x-ray film or nuclear emulsion produced by the pattern of decay emissions (e.g.Breast engorgementCancer/testis antigen family 45, member a5Rombo syndrome: Rombo syndrome is a very rare genetic disorder characterized mainly by atrophoderma vermiculatum of the face,James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology.Laser ablation of thyroid nodules: Laser ablation of thyroid nodules is a minimally invasive procedure indicated to treat benign thyroid lesions such as cold nodules or single nodules within a multinodular goiter. The technique consists in the destruction of the tissue by the insertion therein of optical fibers which convey the light energy, causing a complete and not reversible lesions necrosis.Immunostaining: Immunostaining is a general term in biochemistry that applies to any use of an antibody-based method to detect a specific protein in a sample. The term immunostaining was originally used to refer to the immunohistochemical staining of tissue sections, as first described by Albert Coons in 1941.FormaldehydeDissection puzzle: A dissection puzzle, also called a transformation puzzle or Richter Puzzle, is a tiling puzzle where a set of pieces can be assembled in different ways to produce two or more distinct geometric shapes. The creation of new dissection puzzles is also considered to be a type of dissection puzzle.
