Histology

Signs of losing fetal tissue may include heavy vaginal bleeding, passing of tissue or clots, and cramping or pain in the lower abdomen. If you suspect you have lost fetal tissue, it's important to seek medical attention promptly to ensure proper evaluation and care.

• Artificial Technologies, Inc. (AT) was established in New Haven, Connecticut in 2011 to commercialize applications of its proprietary multilayer polypeptide nanofilm technology. Development of the technology began in 2001 at Louisiana Tech University, led by Dr. Donald Haynie. Dr. Haynie perfected the techniques to design and construct stable, controllable, and versatile polypeptide nanofilms using a reliable layer-by-layer assembly method. This method allows for the creation of nanofilms on surfaces of virtually any shape or size, including films or coatings on flat surfaces as well as films on round template particles which create micro- or nano-capsules. athas exclusively licensed this technology from Louisiana Tech University

Microtome in histology is used for cutting thin, precise sections of tissue samples for microscopic examination. It allows for the preparation of consistent and standardized tissue slices for staining and analysis. This precision helps in identifying cellular structures and abnormalities in tissues.

Yes, neural tissue is considered soft tissue. Soft tissues are tissues that support, connect, or surround other structures and usually have a softer consistency compared to bones. Neural tissue includes the brain, spinal cord, and nerves, which are all made up of cells and fibers that are softer and more pliable compared to bones.

A histology test on a placenta involves examining tissue samples under a microscope to assess the structure and abnormalities. It can provide information on the health of the placenta, fetal development, and any potential issues that may have affected the pregnancy or delivery.

Nonciliated simple columnar epithelium is a type of tissue found in the body that consists of a single layer of column-shaped cells without cilia or hair-like projections. It is primarily involved in absorption and secretion functions, and can be found lining the digestive tract, reproductive organs, and some parts of the respiratory system.

Acids, alkaline substances, strong oxidizing agents, and certain toxic chemicals can destroy living tissue. These substances can cause burns, corrosion, and necrosis of the tissue upon contact. It is important to handle such materials with caution and use appropriate safety measures to prevent harm.

In the histology laboratory, precautions should be taken to minimize exposure to chemicals, biological materials, and sharp objects. These may include wearing appropriate personal protective equipment, handling specimens carefully, following standard operating procedures, and ensuring proper ventilation in the lab. Regular training on safety protocols and emergency procedures is also important.

The most commonly used fixative for routine histology is formalin, specifically buffered formalin. This fixative helps preserve tissues by stabilizing proteins and preventing degradation, allowing for better preservation of cellular structures for microscopic examination.

Host tissue refers to the cells, tissues, or organisms that provide the environment for a parasite or pathogen to live and reproduce. It can be human, animal, or plant cells that are susceptible to infection or infestation by a foreign organism.

1. Deparaffinize and hydrate tissue sections.
2. Stain with a 1% solution of potassium permanganate for 5 minutes.
3. Rinse with tap water.
4. Counterstain with a 1% solution of oxalic acid for 1-2 minutes.
5. Rinse and dehydrate before mounting with a coverslip.

The basement membrane binds epithelial tissue to underlying connective tissue. It provides structural support, filtration, and helps regulate the exchange of molecules between the epithelial cells and the underlying tissues.

The histology laboratory plays a crucial role in clinical diagnosis by examining tissue samples to identify abnormalities, diseases, and conditions at a cellular level. Pathologists analyze the samples using various techniques to provide accurate diagnoses, which help guide treatment decisions for patients. The histology laboratory ensures that the information obtained from tissue samples contributes to the overall clinical management and care of patients.

Superficial tissue refers to the outermost layer of the body, such as the skin, subcutaneous tissue, and mucous membranes. It provides protection against external forces, regulates temperature, and helps in sensation perception.

villi, which are finger-like projections that increase surface area for absorption; crypts of Lieberkühn, which are invaginations where new epithelial cells are produced; and the presence of various cell types, including enterocytes, goblet cells, Paneth cells, and enteroendocrine cells.

The digestive tract is lined with different types of epithelial cells that perform different functions. For example, columnar cells in the small intestine aid in absorption, while goblet cells secrete mucus for lubrication and protection. Smooth muscle cells in the muscularis layer help propel food along the tract through peristalsis.

No, histology is a common noun. It refers to the study of the microscopic structure of tissues.

Spongy bone is the tissue that makes up the interior of bones; compact bone is the tissue that forms the surface of bones. In long bones, spongy bone forms the interior of the epiphyses; the diaphysis (shaft) consists of compact bone surrounding the central marrow cavity.

Spongy bone can also be found in the rib slide (21). It contains large marrow spaces defined by shelves and spicules of bone. The inner space is lined by osteoblasts and osteoclasts (called the endosteum). Osteocytes can be seen in layers in adult spongy bone. Outside all of bone, is a connective tissue sheath called the periosteum. It contains inner layers of osteogenic cells that can give rise to osteoblasts and make new bone,.

Tissue plasminogen activator (tPA) is administered to patients experiencing acute ischemic stroke to help dissolve blood clots and improve blood flow to the brain. It is a clot-busting medication that can help reduce the severity of a stroke if administered within a specific time window after symptoms start.

Hematoxylin stain is used in histology to selectively stain cell nuclei blue, allowing for better visualization of tissue morphology and structures. It serves as a contrast stain in combination with eosin stain, highlighting cellular and tissue features for microscopic analysis and diagnosis.

Haematoxylin stain is commonly used in histology to stain cell nuclei blue/purple, helping to visualize their morphology and distribution within tissues. It serves as a contrast stain to highlight the cellular details when combined with counterstains like eosin. This staining method is crucial for distinguishing different cell types, aiding in the accurate interpretation of tissue structures in histological slides.

Inflammation of bony tissue is known as osteomyelitis. It is usually caused by a bacterial infection that can spread through the bloodstream or from nearby tissue. Symptoms can include pain, swelling, redness, and fever.

A red-top tube with no anticoagulant is typically used for histology. This allows for the blood to clot and separate, leaving the serum available for further testing.

Tissue is a general term referring to a group of similar cells that work together to perform a specific function in the body. Collagen is a type of protein that is the main component of connective tissues in the body. So, tissue can contain collagen as one of its components.
