Formaldehyde
A highly reactive aldehyde gas formed by oxidation or incomplete combustion of hydrocarbons. In solution, it has a wide range of uses: in the manufacture of resins and textiles, as a disinfectant, and as a laboratory fixative or preservative. Formaldehyde solution (formalin) is considered a hazardous compound, and its vapor toxic. (From Reynolds, Martindale The Extra Pharmacopoeia, 30th ed, p717)
Fixatives
Agents employed in the preparation of histologic or pathologic specimens for the purpose of maintaining the existing form and structure of all of the constituent elements. Great numbers of different agents are used; some are also decalcifying and hardening agents. They must quickly kill and coagulate living tissue.

Tumor Markers, Biological
Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or body fluids. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including hormones, antigens, amino and nucleic acids, enzymes, polyamines, and specific cell membrane proteins and lipids.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

Oils
Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)

Histocytochemistry
Neoplasm Proteins
Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.

Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Emulsions
Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.

Keratins
A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.

Loss of PTEN expression in paraffin-embedded primary prostate cancer correlates with high Gleason score and advanced stage. (1/216)
The tumor suppressor gene PTEN/MMAC-1/TEP-1 (referred to hereafter as PTEN) maps to chromosome 10q23 and encodes a dual specificity phosphatase. The PTEN protein negatively regulates cell migration and cell survival and induces a G1 cell cycle block via negative regulation of the phosphatidylinositol 3'-kinase/protein kinase B/Akt signaling pathway. PTEN is frequently mutated or deleted in both prostate cancer cell lines and primary prostate cancers. A murine polyclonal antiserum was raised against a glutathione S-transferase fusion polypeptide of the COOH terninus of PTEN. Archival paraffin tissue sections from 109 cases of resected prostate cancer were immunostained with the antiserum, using DU145 and PC-3 cells as positive and negative controls, respectively. PTEN expression was seen in the secretory cells. Cases were considered positive when granular cytoplasmic staining was seen in all tumor cells, mixed when areas of both positive and negative tumor cell clones were seen, and negative when adjacent benign prostate tissue but not tumor tissue showed positive staining. Seventeen cases (15.6%) of prostate cancer were positive, 70 cases (64.2%) were mixed, and 22 cases (20.2%) were negative. Total absence of PTEN expression correlated with the Gleason score (P = 0.0081) and correlated more significantly with a Gleason score of 7 or higher (P = 0.0004) and with advanced pathological stage (American Joint Committee on Cancer stages T3b and T4; P = 0.0078). Thus, loss of PTEN protein is correlated with pathological markers of poor prognosis in prostate cancer. (+info)Recovery of ranavirus dsDNA from formalin-fixed archival material. (2/216)
The extraction and amplification of nucleic acid from formalin-fixed and paraffin-embedded tissues has become an important exercise in the collection of retrospective epidemiological data. A protocol is described that enables the extraction and amplification of dsDNA from fixed tissues within paraffin blocks and from specimens stored in 10% (aq) formalin. The procedure can be used for the examination of ranavirus DNA within archival tissues thereby providing valuable data for identifying the origin and tracing the spread of ranaviruses. (+info)Relation between antigen release and immune response of oil adjuvanted vaccines in chickens. (3/216)
The relationship between release properties of the model antigen, bovine serum albumin (BSA), from formulations in vitro and immune response after administration of various oil adjuvanted vaccines containing liquid paraffin was examined in chickens. The vaccine prepared at an hydrophile-lipophile-balance (HLB) number of 4.8 showed slower release of BSA and higher immune response on injected chickens than that with an HLB number of 6.0. Decreases of aqueous volume ratio in the formulation also led to slower release of BSA and higher immune response. The slower release rate of BSA showed higher ELISA antibody titer even at 20 weeks after vaccination. The ELISA antibody titer inversely was related to the constant release rate, k, calculated from the in vitro release test. The correlation coefficient was 0.863. The immune response of oil adjuvanted vaccines containing Haemophilus paragallinarum agreed well with these results with BSA. Our results indicated that a stronger and more prolonged immune response of oil adjuvanted vaccines was achieved by slower release rate of antigen from the formulation. In addition, there was a good correlation between immune response and the value of k. (+info)Immunofluorescent detection of alpha1-antitrypsin in paraffin embedded liver tissue. (4/216)
Alpha1-antitrypsin was detected by indirect immunofluorescence in frozen sections of liver biopsies from patients with clinically and biochemically proven alpha1-antitrypsin deficiency. The antigen could also be demonstrated in those liver specimens of the same patients which were fixed in Bouin's fluid and embedded in paraffin. The cellular localization and the brightness of the fluorescence were the same in both frozen and paraffin sections. Four additional biopsies from three other patients were selected on the basis of PAS-positive diastase-resistant inclusions reported in the hepatocytes. All these biopsies showed bright fluorescence in the cytoplasm of the liver cells although one of the biopsies was stored for as long as eight years. Specific fluorescence was constantly found in the periportal hepatocytes with varying degrees of positivity. No fluorescence was observed in the six control biopsies from patients with various other liver diseases. These findings prove that paraffin embedded specimens are suitable for immunofluorescence detection of alpha1-antitrypsin and that a retrospective study on old paraffin blocks is possible. (+info)Cutaneous necrosis due to cetrimide application. (5/216)
Reports of necrosis caused by quaternary ammonium compounds, such as cetrimide, are rare. The case is reported of a 77-year-old woman who was admitted to hospital for four months with cutaneous necrosis of the left foot and leg owing to the topical application of cetrimide powder. (+info)Congenital-infantile fibrosarcoma. A clinicopathologic study of 10 cases and molecular detection of the ETV6-NTRK3 fusion transcripts using paraffin-embedded tissues. (6/216)
Congenital-infantile fibrosarcoma (CIFS) is a relatively indolent sarcoma that should be distinguished from more aggressive spindle cell sarcomas of childhood. CIFSs have been found to have a novel recurrent reciprocal translocation t(12;15)(p13;q25) resulting in the gene fusion ETV6-NTRK3 (ETS variant gene 6; neurotrophic tyrosine kinase receptor type 3). We studied immunohistochemical expression of NTRK3, and conducted a reverse transcription-polymerase chain reaction (RT-PCR) assay to detect the ETV6-NTRK3 fusion transcripts using archival formalin-fixed paraffin-embedded tissues from 10 CIFSs. Thirty-eight other spindle cell tumors were included as controls. The ETV6-NTRK3 fusion transcripts were identified in 7 (70%) of 10 CIFSs. Nucleotide sequence analysis showed that the fusion occurred between ETV6 exon 5 and NTRK3 exon 13. The 38 control tumors were negative for the fusion transcript. Immunohistochemically, CIFSs consistently expressed NTRK3. But the expression of NTRK3 also was observed in 22 of 38 control tumors. These results show the diagnostic usefulness of RT-PCR methods to detect ETV6-NTRK3 fusion transcripts in archival formalin-fixed paraffin-embedded tissue and the important role of NTRK3 in the development of CIFS, despite its being a protein of little importance in differential diagnosis. (+info)Increasing the number of synapses modifies olfactory perception in Drosophila. (7/216)
The Drosophila mutant gigas produces an enlargement of postmitotic cells caused by additional rounds of DNA replication. In neurons, the mutant cell establishes more synapses than normal. We have taken advantage of this feature to study the effect of synapse number on odorant perception. Mosaic adults were generated in which one antenna was homozygous for gigas, whereas the contralateral side served as an internal control. Morphological analysis indicates that the number and type of sensory afferents forming the mutant antenna, as well as their projection to the olfactory glomeruli, are normal. In contrast, the volume of identified glomeruli increases to a variable extent, and mutant sensory neurons branch profusely. The number of synapses, estimated in the ventral (V) glomerulus that receives ipsilateral afferents only, is increased twofold to threefold. Large-dense-core vesicle-containing terminals that probably modulate olfactory centers are identified in the V glomerulus. Their number and size are not modified by the mutant input. Sensory transduction, measured by electroantennograms, is normal in amplitude and kinetics. In odorant tests, however, the profile of the behavioral response to ethyl acetate shows attractive responses to concentrations to which sibling controls remain indifferent (10(-)8 and 10(-)7 v/v). In addition, the intensity of the response is augmented both at attractive and repulsive odorant concentrations with respect to that of controls. These results demonstrate that increased synapse number in the sensory neurons can modify the behavior of the organism, allowing a higher sensitivity of perception. (+info)Cyclin D1 overexpression in multiple myeloma. A morphologic, immunohistochemical, and in situ hybridization study of 71 paraffin-embedded bone marrow biopsy specimens. (8/216)
Cyclin D1 expression was evaluated by immunohistochemical analysis and biotin-labeled in situ hybridization (ISH) in a series of 71 decalcified, paraffin-embedded bone marrow biopsy specimens from patients with multiple myeloma (MM). Cyclin D1 messenger RNA (mRNA) overexpression was detected by ISH in 23 (32%) of 71 cases, whereas cyclin D1 protein was identified by immunohistochemical analysis in 17 (24%) of 71 specimens. All cases that were positive by immunohistochemical analysis also were positive by ISH. Statistically significant associations were found between cyclin D1 overexpression and grade of plasma cell differentiation and between cyclin D1 overexpression and extent of bone marrow infiltration. Our findings demonstrate the following: (1) ISH for cyclin D1 mRNA is a sensitive method for the evaluation of cyclin D1 overexpression in paraffin-embedded bone marrow biopsy specimens with MM. (2) ISH is more sensitive than immunohistochemical analysis in the assessment of cyclin D1 expression. (3) Cyclin D1 overexpression in MM is correlated positively with higher histologic grade and stage. (+info) Pneumonia, lipid refers to a type of pneumonia that is caused by the presence of lipids (fats) in the lungs. This condition is also known as lipid pneumonia or fatty acid pneumonia.
The symptoms of lipid pneumonia can be similar to those of other types of pneumonia, such as cough, fever, chills, and difficulty breathing. However, lipid pneumonia may also cause a distinctive "fatty" or "oily" appearance on chest X-rays.
There are several possible causes of lipid pneumonia, including inhalation of lipids from the environment or from certain medical procedures (such as intratracheal lipid injections), and certain underlying medical conditions (such as cystic fibrosis). The diagnosis of lipid pneumonia is typically made through a combination of clinical evaluation, chest X-rays, and laboratory tests.
Treatment of lipid pneumonia usually involves supportive care measures such as oxygen therapy, hydration, and pain management, as well as antibiotics to prevent or treat any underlying bacterial infections. In severe cases, hospitalization may be necessary to monitor and treat the condition.
Prognosis for lipid pneumonia is generally good if treated promptly and effectively, but the condition can be serious and potentially life-threatening if left untreated or if there are underlying medical conditions that complicate treatment.
Breast Neoplasms also known as Breast Cancer, is a condition where abnormal cell growth develops in the breast tissue. It originates from various cell types including milk-producing glands (lobules), milk ducts, connective tissue, and fatty or fibrous tissue.
There are different types of Breast Neoplasms such as:
1. Fibroadenomas: These are benign tumors that are made up of glandular and fibrous tissues. They are usually small and round, with a smooth surface, and can be moved easily under the skin.
2. Cysts: These are fluid-filled sacs that can develop in both breast tissue and milk ducts. They are usually benign and can disappear on their own or be drained surgically.
3. Ductal Carcinoma In Situ (DCIS): This is a precancerous condition where abnormal cells grow inside the milk ducts. If left untreated, it can progress to invasive breast cancer.
4. Invasive Ductal Carcinoma (IDC): This is the most common type of breast cancer and starts in the milk ducts but grows out of them and invades surrounding tissue.
5. Invasive Lobular Carcinoma (ILC): It originates in the milk-producing glands (lobules) and grows out of them, invading nearby tissue.
Breast Neoplasms can cause various symptoms such as a lump or thickening in the breast or underarm area, skin changes like redness or dimpling, change in size or shape of one or both breasts, discharge from the nipple, and changes in the texture or color of the skin.
Treatment options for Breast Neoplasms may include surgery such as lumpectomy, mastectomy, or breast-conserving surgery, radiation therapy which uses high-energy beams to kill cancer cells, chemotherapy using drugs to kill cancer cells, targeted therapy which uses drugs or other substances to identify and attack cancer cells while minimizing harm to normal cells, hormone therapy, immunotherapy, and clinical trials.
It is important to note that not all Breast Neoplasms are cancerous; some are benign (non-cancerous) tumors that do not spread or grow.
Adenocarcinoma is a type of cancer that begins in glandular cells, which are cells that produce fluids or mucus. It is the most common type of cancer found in the digestive tract, breast, and prostate. Adenocarcinomas can be benign (non-cancerous) or malignant (cancerous). Malignant adenocarcinomas can invade nearby tissues and spread to other parts of the body through the bloodstream or lymphatic system.
Adenocarcinoma is a term used to describe a variety of different types of cancer that arise in glandular tissue, including:
1. Colorectal adenocarcinoma (cancer of the colon or rectum)
2. Breast adenocarcinoma (cancer of the breast)
3. Prostate adenocarcinoma (cancer of the prostate gland)
4. Pancreatic adenocarcinoma (cancer of the pancreas)
5. Lung adenocarcinoma (cancer of the lung)
6. Thyroid adenocarcinoma (cancer of the thyroid gland)
7. Skin adenocarcinoma (cancer of the skin)
The symptoms of adenocarcinoma depend on the location of the cancer and can include:
1. Blood in the stool or urine
2. Abdominal pain or discomfort
3. Changes in bowel habits
4. Unusual vaginal bleeding (in the case of endometrial adenocarcinoma)
5. A lump or thickening in the breast or elsewhere
6. Weight loss
7. Fatigue
8. Coughing up blood (in the case of lung adenocarcinoma)
The diagnosis of adenocarcinoma is typically made through a combination of imaging tests, such as CT scans, MRI scans, and PET scans, and a biopsy, which involves removing a sample of tissue from the affected area and examining it under a microscope for cancer cells.
Treatment options for adenocarcinoma depend on the location of the cancer and can include:
1. Surgery to remove the tumor
2. Chemotherapy, which involves using drugs to kill cancer cells
3. Radiation therapy, which involves using high-energy X-rays or other particles to kill cancer cells
4. Targeted therapy, which involves using drugs that target specific molecules on cancer cells to kill them
5. Immunotherapy, which involves using drugs that stimulate the immune system to fight cancer cells.
The prognosis for adenocarcinoma is generally good if the cancer is detected and treated early, but it can be more challenging to treat if the cancer has spread to other parts of the body.
Adenofibroma is a rare benign tumor that develops in the glands or ducts of the sweat glands. It can occur in any part of the body where there are sweat glands, but it most commonly occurs on the face, neck, and scalp.
Adenofibromas are usually slow-growing and do not spread to other parts of the body. They may be small and firm or large and soft to the touch. They can be skin-colored or pink, and they may have a rough surface.
The cause of adenofibroma is not known, but it is thought to arise from abnormal growth of sweat gland cells. It is usually diagnosed by a dermatologist or a pathologist who examines a sample of the tumor under a microscope.
Treatment for adenofibroma is usually not necessary unless the tumor is causing symptoms or is cosmetically bothersome. In these cases, surgical removal of the tumor may be recommended. Complete removal of the tumor is usually possible, and the prognosis is excellent.

Squamous cell carcinoma (SCC) is a type of skin cancer that develops in the squamous cells, which are thin, flat cells located in the outermost layer of the skin. SCC is one of the most common types of skin cancer and can arise anywhere on the body, including the head and neck, hands, and feet.
SCC typically appears as a firm, flat, or raised bump on the skin, and may be pink, red, or scaly. The cancer cells are usually well-differentiated, meaning they resemble normal squamous cells, but they can grow rapidly and invade surrounding tissues if left untreated.
SCC is more common in fair-skinned individuals and those who spend a lot of time in the sun, as UV radiation can damage the skin cells and increase the risk of cancer. The cancer can also spread to other parts of the body, such as lymph nodes or organs, and can be life-threatening if not treated promptly and effectively.
Treatment for SCC usually involves surgery to remove the cancerous tissue, and may also include radiation therapy or chemotherapy to kill any remaining cancer cells. Early detection and treatment are important to improve outcomes for patients with SCC.
T-cell lymphoma is a type of cancer that develops in the immune system's T cells, which are responsible for fighting off infections and diseases. There are several subtypes of T-cell lymphoma, including:
* Peripheral T-cell lymphoma (PTCL): This is a rare type of T-cell lymphoma that can develop in the skin, lymph nodes, or other organs.
* Cutaneous T-cell lymphoma (CTCL): This is a type of PTCL that affects the skin and can cause lesions, rashes, and other skin changes.
* Anaplastic large cell lymphoma (ALCL): This is a rare subtype of PTCL that can develop in the lymph nodes, spleen, or bone marrow.
* Adult T-cell leukemia/lymphoma (ATLL): This is a rare and aggressive subtype of PTCL that is caused by the human T-lymphotropic virus type 1 (HTLV-1).
Symptoms of T-cell lymphoma can include:
* Swollen lymph nodes
* Fever
* Fatigue
* Weight loss
* Night sweats
* Skin lesions or rashes
Treatment options for T-cell lymphoma depend on the subtype and stage of the cancer, but may include:
* Chemotherapy
* Radiation therapy
* Immunotherapy
* Targeted therapy
Prognosis for T-cell lymphoma varies depending on the subtype and stage of the cancer, but in general, the prognosis for PTCL is poorer than for other types of non-Hodgkin lymphoma. However, with prompt and appropriate treatment, many people with T-cell lymphoma can achieve long-term remission or even be cured.
A malignant tumor that originates in the milk ducts of the breast. It is the most common type of breast cancer and typically affects women after the age of 50. The tumors are often small at first and may not cause any symptoms, but as they grow, they can invade nearby tissue and spread to other parts of the body (metastasize).
The exact cause of ductal carcinoma is unknown, but certain risk factors such as family history, genetics, hormone replacement therapy, obesity, and delayed childbearing have been linked to its development. Early detection through mammography and breast self-examination can improve survival rates, which are generally high for women diagnosed with this type of cancer if caught early. Treatment typically involves surgery to remove the tumor (lumpectomy or mastectomy), followed by radiation therapy and/or chemotherapy.
