Carcinoma due to chronic pernicious anemia develops in?
-
Pylorus
-
Body
-
Fundus
-
All
Correct Answer
A. FundusExplanation
Carcinoma due to chronic pernicious anemia develops in the fundus. Chronic pernicious anemia is a condition characterized by the inability to absorb vitamin B12, leading to a deficiency. This deficiency can cause changes in the gastric mucosa, including atrophy and metaplasia. The fundus of the stomach is particularly affected by these changes, making it more susceptible to the development of carcinoma. Therefore, the fundus is the most likely site for the development of carcinoma in individuals with chronic pernicious anemia.Rate this question:

The best method for confirming amyloidosis?
-
Tongue biopsy
-
Rectal biopsy
-
Colonoscopy
-
Sigmoidoscopy
Correct Answer
A. Rectal biopsyExplanation
A rectal biopsy is the best method for confirming amyloidosis because it allows for the direct examination of the rectal tissue, which is commonly affected by amyloid deposits. During a rectal biopsy, a small sample of tissue is taken from the rectum and examined under a microscope for the presence of amyloid deposits. This method provides a more accurate diagnosis compared to other options such as tongue biopsy, colonoscopy, or sigmoidoscopy, which may not specifically target the affected area or provide sufficient tissue samples for analysis.Rate this question:

Cell cycle regulating oncogene?
-
CDK4
-
Myc
-
Erb
-
Sis
Correct Answer
A. CDK4Explanation
CDK4 is a cell cycle regulating oncogene. It plays a crucial role in controlling the progression of the cell cycle by forming a complex with cyclin D and phosphorylating the retinoblastoma protein (Rb). This phosphorylation releases Rb's inhibitory effect on the cell cycle, allowing the cell to proceed from the G1 to the S phase. Dysregulation of CDK4 can lead to uncontrolled cell growth and division, contributing to the development of cancer. Therefore, CDK4 is a key player in cell cycle regulation and a potential target for cancer therapies.Rate this question:

Hemodialysis associated amyloid?
-
Isolated amyloid
-
Beta 2 microglobulin
-
Gamma albumin
-
Delta fibrin
Correct Answer
A. Beta 2 microglobulinExplanation
Hemodialysis-associated amyloidosis is a condition that occurs in patients undergoing long-term hemodialysis. It is characterized by the deposition of amyloid fibrils in various tissues, particularly in joints and bones. The main component of these amyloid fibrils is Beta 2 microglobulin, which is a protein that is normally present on the surface of cells and is involved in immune response. However, in patients with end-stage renal disease undergoing hemodialysis, Beta 2 microglobulin accumulates in the blood due to impaired clearance by the kidneys, leading to its deposition as amyloid fibrils. Therefore, Beta 2 microglobulin is the correct answer in this context.Rate this question:

Not a feature of apoptosis?
-
Cellular swelling
-
Nuclear compaction
-
Intact cell membrane
-
All
Correct Answer
A. Cellular swellingExplanation
Apoptosis is a programmed cell death process that occurs in multicellular organisms. During apoptosis, cells undergo a series of controlled events that ultimately lead to their death. One of the characteristic features of apoptosis is the shrinkage of the cell, not cellular swelling. Therefore, cellular swelling is not a feature of apoptosis. Instead, apoptosis involves nuclear compaction, which refers to the condensation and fragmentation of the cell's nucleus. Additionally, apoptosis also involves the maintenance of an intact cell membrane until the final stages of the process.Rate this question:

Onion thickening of arteriolar walls seen in?
-
Garres osteomyelitis
-
Hyaline arteriosclerosis
-
Raynauds disease
-
Beurgers disease
Correct Answer
A. Hyaline arteriosclerosisExplanation
Hyaline arteriosclerosis is a condition characterized by the thickening and hardening of the arteriolar walls. This occurs due to the deposition of a protein called hyaline in the walls of small arteries and arterioles. This condition is commonly associated with chronic hypertension and diabetes. It can lead to a decrease in blood flow and oxygen supply to various organs, potentially causing organ damage. Garres osteomyelitis is a bone infection, Raynaud's disease is a condition characterized by the narrowing of blood vessels in response to cold or stress, and Beurgers disease is a condition that involves inflammation and clotting of the small and medium-sized arteries in the extremities.Rate this question:

Edema in nephrotic syndrome caused by?
-
Na and water restriction
-
Hypoalbuminemia
-
Hyperlipidemia
-
None
Correct Answer
A. HypoalbuminemiaExplanation
In nephrotic syndrome, there is a significant loss of protein, particularly albumin, through the urine. This leads to a decrease in the levels of albumin in the blood, known as hypoalbuminemia. Albumin plays a crucial role in maintaining the balance of fluids in the body by exerting an osmotic pressure that keeps fluid within the blood vessels. When albumin levels are low, the osmotic pressure decreases, causing fluid to leak out of the blood vessels and accumulate in the tissues, resulting in edema. Therefore, hypoalbuminemia is the main cause of edema in nephrotic syndrome.Rate this question:

Does Berry aneurysm defect lie in______________
-
Degeneration of media layer
-
Inflammation in vessel wall
-
Degeneration of internal elastic lamina
-
None
Correct Answer
A. Degeneration of media layerExplanation
Berry aneurysm is a type of aneurysm that occurs in the brain's blood vessels. It is characterized by a bulging or ballooning of the blood vessel wall, usually at a weak point where the vessel branches. The correct answer, "Degeneration of media layer," refers to the degeneration of the middle layer of the blood vessel wall, known as the media. This degeneration weakens the vessel wall, making it more prone to bulging and forming an aneurysm. Inflammation in the vessel wall and degeneration of the internal elastic lamina can also contribute to the development of a berry aneurysm, but the degeneration of the media layer is the primary factor.Rate this question:

Schilling test is used to find out ?
-
Gastric indigestion
-
Vit B9 malabsorption
-
Intestinal metaplasia
-
Vit.B12 malabsorption
Correct Answer
A. Vit.B12 malabsorptionExplanation
The Schilling test is a diagnostic test used to determine the cause of vitamin B12 malabsorption. This test involves the administration of radioactive vitamin B12 and measuring the amount of radioactivity excreted in the urine. If there is a deficiency in the absorption of vitamin B12, it can lead to various symptoms such as anemia, fatigue, and neurological problems. Therefore, the Schilling test is used to identify the underlying cause of vitamin B12 malabsorption, which can be due to factors such as pernicious anemia or gastrointestinal disorders.Rate this question:

In tumour Telomerase get?
-
Reactivated
-
Inactivated
-
No change
-
Minimal change
Correct Answer
A. ReactivatedExplanation
Telomerase is an enzyme that helps maintain the length of telomeres, which are protective caps at the ends of chromosomes. In normal cells, telomerase is usually inactive, preventing unlimited cell division. However, in cancer cells, telomerase can be reactivated, allowing the cells to continuously divide and grow. Therefore, the correct answer is "Reactivated" as tumour cells often have increased telomerase activity compared to normal cells.Rate this question:
