Epidemiology The videoconferencing of a rural primary care physician and an OHSU specialist is best described as:

Epidemiology HIPAA allows for limited use of patient information for treatment, payment, and operations (TPO) without explicit consent. In which of the following situations is sharing of patient data NOT permitted?

Anatomy A 36-year-old man is brought to the emergency department because of a deep knife wound on the medial side of his distal forearm. He is unable to hold a piece of paper between his fingers and has sensory loss on the medial side of his hand and little finger. Which nerve is most likely injured?

Embryology A recent case study reported on twins experiencing congenital chest pains. Echocardiographic imaging reveals that the infants each had a defect that permitted the herniation (abnormal passage) of the left auricle of the heart into the left pleural cavity. Which of the following defects might allow a portion of the heart to move abnormally into the space normally occupied by the lungs?

Embryology (Copenhaver) Once the lesser omentum has formed, it will extend between which two structures?

Histology Blood Leukocytes are characterized by their nuclear morphology. Monocytes have variable nuclear shapes and are classified as which of the following?

Formation of body cavities Which component of the embryonic lung will be formed by the somatic mesoderm from the lateral plate region?

Anatomy: limbs 17-year-old football player presents to the emergency department with extreme pain in his leg after a particularly brutal tackle during a game. The attending physician determines that he is suffering from compartment syndrome compression of the muscles and neurovascular structures due to bleeding and swelling in the leg. The patient is transferred immediately to the OR. To preserve the integrity of the muscles and neurovascular structures, which of the following structures should be cut to release the pressure?

Histology: Blood, connective tissue, adipose Major Basic Protein is associated with killing of helminthic (parasitic) worms. What type of cell produces and secretes Major Basic Protein?

Histology: Blood, connective tissue, adipose During congestive heart failure, the liver may not get sufficient oxygenated blood to meet its metabolic needs. A pathologist can detect this problem by inspection of a liver biopsy and noting the pattern of dying hepatocytes. Based on your knowledge of normal histology, where would you expect the pathologist to see the most pathologic changes in these cells?

Histology: Blood, connective tissue, adipose The primary function of multilocular adipocytes is which of the following?

Limbs (Nelsen) A 42-year-old painter visits the orthopedics clinic complaining of weakness of her upper limb. Physical examination suggests involvement of the posterior cord of the brachial plexus. Which action would be affected?

CAD (Wojcik) To detect subclinical coronary artery disease, which of the following methods is commonly used?

CAD (Wojcik) Regardless of intervention used, a decrease in LDL-C levels by 1 mmol/L (38.7 mg/dL) can reduce the relative risk of a major cardiovascular event by which of the following percentages?

GWAS (Spellman) Imagine that 10,000 generations ago a new mutation was generated that can cause tall stature and green skin. The mutation has passed through the population but is very rare and not fully penetrant. You are interested in identifying this mutation and seek to use the property of linkage disequilibrium to find it. The most effective strategy to find this variant would be which of the following?

GWAS (Spellman) In a condition such as colon cancer, the risk will be least for which of the following relatives of an affected individual?

Intercellular Junctions (Musil) Which of the following substances is excluded from all gap junction channels?

Intercellular Junctions (Musil) If the lateral plasma membranes of a confluent monolayer of epithelial cells were completely fused to each other, what would happen to the transepithelial resistance (TER)?

Intercellular Junctions (Musil) The adhesive function of the classical cadherin E-cadherin is directly regulated by which of the following?

Lipoproteins (Wojcik) Which lipoprotein fraction is called atherogenic cholesterol?

Lipoproteins (Wojcik) Henry is a 56 year-old male with well-controlled hypertension who comes to the office for an annual visit. His physical exam is completely normal. As part of the routine labs, you obtain a fasting lipid panel. The results are reported as follows: Total Cholesterol - 174 Triglycerides 97 HDL-cholesterol 60 LDL-cholesterol -95 In this case, which one of the values is calculated rather than measured directly?

Mevalonate (Duell) Which of the following genes is most frequently mutated in familial hypercholesterolemia?

Mevalonate (Duell) Cholesterol is a substrate for which of the following?

Mevalonate (Duell) Sterol regulatory element binding protein-2 (SREBP-2) is involved in which of the following functions?

Mevalonate (Duell) The rate limiting enzyme for cholesterol synthesis is which of the following?

Sorting (Mayinger) Using genetic engineering techniques, you have created a protein that contains two conflicting sorting sequences that specify different compartments: A cleavable N-terminal signal sequence for mitochondrial targeting and a C-terminal KDEL peptide that mediates retrieval to the ER via KDEL receptor and COP-I vesicular traffic. Where would this protein most likely end up?

Sorting (Mayinger) What is the role of the nuclear localization sequence in a nuclear protein?

Nutrition (Stadler) Preconception folic acid supplementation is recommended to decreases the risk in offspring of which of the following conditions?

Vitamins (Stadler) Vitamin C is an essential water soluble vitamin required for:
