Pathology

Pathology is the scientific study of the nature of disease and its causes, processes, development, and consequences. It deals with the study of mechanisms and manifestations of disease, and involves the study of bodily changes that occur as the result of disease. This category is for questions about pathology, the study of disease and its causes, development, and consequences.

How does the activity of the enzyme will be more than 100 percent?

An enzyme's activity can appear to exceed 100% due to a cascade effect where the enzyme catalyzes multiple cycles of a reaction, leading to a cumulative amplification of the reaction. However, it is important to note that enzyme activity is typically expressed as a rate, which is a measure of the amount of substrate converted per unit time, and therefore cannot be greater than 100%.

What is a semi diurnal wave?

A semi-diurnal wave is a type of tidal wave that has two high tides and two low tides of approximately equal size within a 24-hour period. This wave pattern is commonly observed in many coastal areas around the world.

Whih disease is produced by ameoba?

Amebic dysentery is a disease caused by the parasite Entamoeba histolytica. Symptoms include severe diarrhea, abdominal cramps, and fever. It is typically contracted through contaminated food or water.

What does trabecular thickening mean?

Trabecular thickening refers to an increase in the density or bulk of the trabecular bone, which is the spongy network of bone tissue found at the ends of long bones and within the vertebrae. This can be a response to increased mechanical loading or as part of the aging process to provide greater structural support and strength to the bone.

Name for pathology method to report cervical cytology?

The name for the pathology method to report cervical cytology is called the Bethesda System. It is a standardized method used to classify and report cervical cytology results, providing consistent terminology for healthcare professionals to communicate findings accurately.

What is Discohesive clusters of atypical epithelial cells seen?

The short answer is, a problem for whatever the sample was removed from. Breaking down the phrase, we have:

1. Discohesive (pronounced dis-co-HE-sive) - the cells are not organized (cohesive); the cells are arranged in an abnormal pattern

2. Clusters - the cells are making little islands of themselves rather than arranging as a continuous sheet or structure

3. Atypical - not normal; showing signs of genetic or structural changes

4. Epithelial - a cell classification associated with the linings of organs as well as with the production of enzymes or hormones

Putting everything back together, you have abnormal, organ lining or organ forming cells that are not organized and are gathered into little groups. In practical terms, this is likely either a cancer or a pre-cancerous growth that is invading and expanding into the local normal tissues.

Why is phenylalanine observed in the urine of a classical PKU patient?

PKU stands for phenylketonuria, the classic symptom of which (and the diagnostic test for the disease) is phenylalanine in the urine. This is a genetic disorder in which the body is unable to process phenylalalanine, so it is excreted in the urine.

Why goiter is more common in women than in men?

Women are more prone to goiter due to hormonal changes during puberty, pregnancy, and menopause, as well as hormonal imbalances, such as thyroid disorders. Estrogen can stimulate the growth of thyroid tissue, leading to an increased risk of goiter in women compared to men. Additionally, women are more likely to develop autoimmune thyroid diseases, which can also contribute to goiter formation.

The process where bleeding is stopped?

The process of stopping bleeding is called hemostasis. It involves the constriction or narrowing of blood vessels, formation of a platelet plug to temporarily block the bleeding, and activation of the coagulation cascade to form a stable blood clot. This process is crucial for maintaining normal blood circulation and preventing excessive blood loss.

What is the function of a slime capsule in a bacterial cell?

A slime capsule in a bacterial cell provides protection against desiccation (drying out), phagocytosis by immune cells, and chemical attack. It also helps the bacteria adhere to surfaces and form biofilms.

Define bacteria discuss the morphology and pathogenesisof any pyogenic bacteria?

Bacteria are single-celled microorganisms that can be beneficial or harmful to humans. Pyogenic bacteria are a type of bacteria that can cause pus formation by promoting inflammation and infection. Morphologically, they can be spherical (cocci) or rod-shaped (bacilli), and some examples include Staphylococcus aureus and Streptococcus pyogenes. These bacteria can invade tissues, produce toxins, and trigger an immune response, leading to symptoms like fever and localized inflammation.

What are people who works with parasites called?

People who work with parasites are typically called parasitologists. They study the biology, ecology, and behavior of parasites, as well as how they interact with their hosts. Parasitologists may work in fields such as biology, veterinary science, or public health.

What is iVDPV?

iVDPV= infective vaccine derived poliovirus

cVDPV= circulating vaccine derived poliovirus

aVDPV= ambiguous vaccine derived poliovirus

They are caused by a mutation regaining virulence in the attenuated poliovirus strains (Sabin 1-3) used for the oral poliomyelitis vaccine (OPV). Not sure of the specific difference between regressed strains though.

What occurs when mast cells and basophil cells degranulate?

When mast cells and basophils degranulate, they release inflammatory mediators such as histamine, cytokines, and leukotrienes. This process plays a key role in triggering allergic reactions and promoting inflammation in response to allergens or pathogens. Symptoms may include itching, swelling, redness, and increased blood flow to the affected area.

How many red blood cells are produced each second?

Roughly about 2.4 million erythrocytes (red blood cells) are produced every second.

What do pathogens cause?

Many pathogens enter the body through the mouth and nose.The linings of the mouth, throat and nose produce mucus which can trap bacteria. This mucus is periodically swallowed and the acid in the stomach kills most of the bacteria. So that's how we get colds and why pathogens make us feel icky and ill.

Why is milk fish called milkfish?

Milkfish got its name because of its milky white coloration and its reputation for having a rich and creamy taste. The name "milkfish" is a direct translation from its Filipino name, "bangus," which is also derived from the same visual and taste characteristics.

What is erythrocytosis?

Erythrocytosis, also known as polycythemia, is a condition characterized by an abnormally high concentration of red blood cells in the bloodstream. This can lead to thickened blood, reduced oxygen delivery to tissues, and an increased risk of blood clots. Erythrocytosis can be caused by various factors, including genetic mutations, chronic hypoxia, and certain medical conditions.

What are the 3 major groups of fungi?

What does proliferation mean?

To grow or multiply by rapidly producing new tissue, parts, cells, or offspring

What are results for a acid-fast test for enterobacter aerogenes?

Enterobacter aerogenes is a gram-negative bacterium and typically does not retain acid-fast stains due to its cell wall structure. Therefore, a positive result on an acid-fast test would be unlikely for Enterobacter aerogenes.

Is an example of an abiotic factor for a given animal?

An example of an abiotic factor for an animal could be temperature. For instance, a high or low temperature could affect the metabolism, behavior, and overall health of an animal.
