Which of the following is a sign of reversible cell injury?

Which of the following will occur in both apoptosis and atrophy?

Which of the following will differentiate necrosis from hypertrophy? Necrosis...

A tissue preparation is experimentally subjected to a hypoxic environment. The cells in this tissue begin to swell, and chromatin begins to clump in cell nuclei. ATPases are activated, and ATP production decreases. Which of the following ions accumulating in mitochondria and the cytosol contributes most to these findings and to eventual cell death?

An 11-year-old girl becomes infected with hepatitis A and experiences mild nausea for 1 week. On physical examination, she has minimal right upper quadrant tenderness and yellowish sclera. Laboratory findings showed elevated liver enzymes. Her laboratory findings most likely result from which of the following

changes in her hepatocytes?

A 72-year-old man died suddenly from congestive heart failure. At autopsy, his heart weighed 580 g (normal 330 g) and showed marked left ventricular hypertrophy, minimal coronary arterial atherosclerosis and calcium deposits on the cusps his aortic valve. Which of the following pathologic processes best accounts for the changes in his aortic valve?

A 68-year-old woman suddenly lost consciousness and on awakening 1 hour later, she could not speak or move her right arm. Two months later, a head CT scan showed a large cystic area in the left parietal lobe. Which of the following pathologic processes has most likely occurred in her brain?

A 63-year-old man has a 2-year history of worsening congestive heart failure. An echocardiogram shows mitral valve stenosis with left atrial dilation. A mural thrombus is present in the left atrium. One month later, he experiences left flank pain and notes hematuria. Embolization of the thrombus has likely led to blockage of a renal arterial branch, causing what type of necrosis in this patient?

Which of the following mechanisms contribute to cellular aging?
