A) Amylase
B) Gastrin
C)Glucagon
D) Human pancreatic polypeptide
E) Insulin
F) Lipase

Unfortunately I answered this question incorrectly. TSH-receptor binding antibodies cross placenta and induce goiter development. Answer is "B".

Just wanted to confirm some answers.

40. A 54-year-old woman who works as a nurse comes to the physician for routine tuberculosis screening. A sample of her whole blood is incubated with a mixture of synthetic peptides representing two proteins of the suspected pathogen. Three days later, supernatant is collected for evaluation. Measurement of which of the following cytokine concentrations is most likely to indicate a positive result?
A) Granulocyte-macrophage colony-stimulating factor
B) Interferon alpha
C) Interferon gamma
D) Interlukein-4
E) IL - 10
F) Transsforming growth factor-beta

Not sure about this one. Answered A which was wrong.


34 A 24-year-old woman was slung on her right thumb by a bee 30 minutes ago. She develops an urticarial lesion at the site of the sting. Six hours later, the area has become indurated and firm. Which of the following explains the induration at the site of the sting?
A) Decrease in the expression of adhesion molecules on vascular endothelial cells
B) Decrease in serum C-reactive protein concentration
C) Influx of macrophages producing interleukin-1, IL-6, and tumor necrosis factor-a
D) Lysis of endothelial cells by the alternative complement pathway
E) Vasoconstriction

Is C right ?

a study is designed to evaluate the relationship b/w ambient noise and hearing loss in an automoblile plant .different location in the manufacturing plant have different levels of ambient noise .each employe is given a test for hearing acuity and the the noise level is measured at his or her workstation which of the following describe this study design a) case series b )cohort c )crossover d )cross sectional e )randomized c trial

D) cross sectional.

measures simultaneously the exposure and the outcome.

It like cutting the population and taking a cross section and checking both the exposure and the outcome i.e checking the Prevalence at that particular point in time.

45. An otherwise healthy 60-year-old man comes to the physician for a follow-up examination 2 weeks after he was found to have a serum prostate-specific antigen concentration of 5.3 ng/mL (N,..4) A biopsy specimen of the prostate shows evidence of adenocarcinoma. A CT scan of the spine shows osteoblastic lesions at LI. The patient undergoes bilateral orchiectomy. Five months later, he dies suddenly of a massive myocardial infarction. At autopsy, which of the following microscopic changes in the prostate resulting from the orchiectomy is most likely present,
A) Corpora amylacea
B) Edema
C) Hypertrophied cells
D) Necrosis of the blood vessel walls
E) Scattered shrunken cells
F) Widespread necrosis

Is it E ?

The pain began almost immediately after this attempt Which of the following is the most likely cause of this patients pain?

A) A fracture of a lumbar vertebra
B)Rupture of the deltoid tendon
C) Rupture of an intervertebral disc

Haven't done nbme16 yet, so I don't know the question. A horseshoe kidney is stuck underneath the inferior mesenteric artery... maybe that helps with the answer, or you just post the answer choices.

surgical approach to repair the aneurysm is further complicated by
abnormal origion of superior mesenteric artery
anomalous origin of multiple renal arteries
multiple ureters with abnormal course
tumors with malignant degenration
friability of vascular tissue collagin synthesis abnormalities (this one is wrong)
