What is toluidine blue stain?
Toluidine blue stain is a synthetic dye commonly used in histology and cytology to highlight cellular structures. It is particularly effective for staining acidic tissue components, such as nucleic acids and glycosaminoglycans, which appear blue under a microscope. The stain is often used in the diagnosis of tumors and in the identification of certain pathogens due to its ability to differentiate between various cell types and tissue components. Additionally, toluidine blue has applications in the assessment of tissue morphology and viability.
What energy required for a seedling to push up out of the ground comes from?
The energy required for a seedling to push up out of the ground mainly comes from stored reserves in the seed itself. As the seed absorbs water and nutrients from the soil, it uses this stored energy to fuel the initial growth and emergence of the seedling. This process is known as germination.
What is bi apical soft tissue densities in the chest?
Biapical soft tissue densities in the chest represent areas of increased density or thickening of the soft tissues at the apices of both lungs. This finding can be associated with various conditions such as scarring from old infections, inflammation, or rarely, malignancies. Further evaluation with imaging studies and clinical assessment is usually required to determine the underlying cause.
What is automatic tissue processing?
Automatic tissue processing is done automatic tissue processor in which we put the reagent ,alcohol,xylene & other required things and set the time. It done tissue processing automaticaly.
What is the emetogenic and tissue damage potential of docetaxel?
Not a highly emetogenic drug. no prophylactic antiemetic required. and is not related with significant tissue damage.
When tissue is heated above 60 degrees C what happen to the tissue?
When tissue is heated above 60 degrees Celsius, it undergoes thermal denaturation, leading to the irreversible unfolding of proteins and disruption of cellular structures. This process can cause cell death, loss of function, and damage to the extracellular matrix. Prolonged exposure to such high temperatures can result in burns and necrosis of the affected tissue. Overall, heating tissue to this extent can severely compromise its integrity and viability.
What is the component in muscle tissue that contains the ATPase activity required for contraction?
myosin
Six to eight servings are required daily to maintain tissue hydration.?
water
What are external factors including shearing forces which may exacerbate tissue viability and skin breakdown?
External factors that can exacerbate tissue viability and skin breakdown include shearing forces, friction, moisture, and pressure. Shearing forces occur when layers of skin move in different directions, causing damage to blood vessels and tissues. Excess moisture from sweat or incontinence can weaken the skin barrier, while prolonged pressure on specific areas can restrict blood flow, leading to tissue ischemia and necrosis. Together, these factors can significantly increase the risk of pressure ulcers and compromise skin integrity.
What is fibro glandular parenchyma?
Fibroglandular parenchyma is the combination of fibrous and glandular tissue found in the breast. This tissue is responsible for producing and transporting milk in breastfeeding women. Changes in fibroglandular tissue density can affect mammography results and breast cancer risk assessment.
How long after a patient's death can nonvital tissue donation occur?
Nonvital tissue donation can typically occur within 24 to 48 hours after a patient's death, depending on the specific type of tissue being donated and the protocols of the donation organization. It's crucial that the donation process begins promptly to ensure the viability of the tissues. Coordination with medical professionals and donation agencies is essential to facilitate timely recovery.
How many cells have to be together to count as tissue?
The minimum number of cells required to count as tissue is one. Animal connective tissue typically has cells scattered throughout an extracellular matrix, as such, a single cell surround by the matrix could be classified as tissue. However, in practice terms, the answer is 'a lot' as distinct cellular specialization into tissue types is not achieved without dozens to trillions of cells.
