1. A 45-year-old man has a myocardial infarction. A coronary stent restores blood flow, but reperfusion causes a paradoxical increase in damage. Which of the following is the most likely mechanism of the new myocardial damage?
A) Direct poisoning of mitochondrial enzymes
B) Increase in lipid peroxidation of membranes
C) Inhibition of ATPase-dependent transport
D) Loss of intracellular amino acids
E) Prevention of cross-linking of labile amino acids
Answer B: WELL,LIPID PEROXIDATES ARE H202 FORMATION ITS LETHAL TO THE MEMBRANES JUST LIKE THE SUPERNOXIDES OH-.

3.) An 82-year-old woman has become increasingly disoriented over the past year. She is pleasant and attempts to be cooperative. She performs poorly on a Mini-Mental State Examination. Pulse is 80/min, and blood pressure is 160/90 mm Hg.

Which of the following is the most likely explanation for these findings?

A) Dementia, Alzheimer's type
B) Huntington's disease
C) Multi-infarct dementia
D) Multiple sclerosis
E) Parkinsonism

I HAD THIS ON MY LAST SET, WELL SORRY GUYS ITS NOT DEMENTIA,ALZHEMIER™S TYPE, CLUE HERE IS MULTI-INFARCT CAUSED BY THE 160/90 mm Hg. HTN and smal lacunar lesions in internal capsule (supplied by lenticulaostriate arteries)

Prior to admission, she had severe excruciating stabbing-like chest pain radiating to her left shoulder. She is anxious and in severe pain. Pulse is 110/min, and blood pressure is 160/80 mm Hg.

SUBSTANCE P(PAIN) IS INVOLVED IN NOCICEPTION,TRANSMITTING INFORMATION ABOUT TISSUE
DAMAGE FROM PERIPHERAL RECEPTORS TO THE CENTRAL NERVOUS SYSTEM TO BE CONVERTED TO THE
SENSATION OF PAIN. IT HAS BEEN THEORIZED THAT IT PLAYS A PART IF FIRBOMYALGIA. CAPAICIN HAS BEEN SHOWN TO REDUCE THE LEVELS OF SUBSTANCE P PROBALLY BY REDUCING THE NUMBER OF C-FIBRE NERVES OR CAUSING
THESE NERVES TO BE MORE TOLERANT.

A previously healthy 32-year-old woman has the onset of recurrent headaches. She develops nausea, vomiting, weakness, abdominal pain, and easy bruisability. Her temperature is 38.5 C (101.3 F). Laboratory studies show:

A) macrocytes

B) schistocytes

C) sickle cells

D) spherocytes

E) target cells


Answer B
Platelet Count is too low. That is why she has easy brusisability.
So something in your head should ring?? The platelets are being used up to form clots THROUGHOUT(HEADACHE,ABDOMINAL PAIN ETC) her body.
. She was already having headaches previously, so these little clots was affecting her slowly, possibly the internal carotids. Well, also we should see fibrin split products too!


THE CONCENT OF HEMOGLOBIN IS LOW BC OF THIS-------(MIA)MICROANGIOPATHIC HEMOLYTIC ANEMIA IS WHAT IS CAUSING US TO PICK SCHISTOCYTES(it™s loss of red blood cells through destruction caused by factors in the small blood vessels. IN ALL CAUSES,THE MOA OF MAHA is the formation of a
Fibrin mesh due to increased activation of the system of coagulation(fibrin is what finalizes the clot-too much is being despositing in tiny vessels) THE RED BLOOD CELLS ARE PHYSICALLY CUT BY THESE PROTEIN NETWORKS AND THE FRAGMENTS ARE IDENTICAL TO THE SCHISTOCYTES.

Most common Causes of MIA:
TTP(NO ADAM3)
HUS
DIC
HEPARIN INDUCED THROMBOCYTOPENIA

22. A 45-year-old man has a 6-month history of burning pain that begins in the epigastric area and ascends into the chest. Episodes occur most frequently after large meals and at night.
