can any one tell me easy way of doing MRI of cruciate ligaments.i am always confusing anterior vs posterior cruciate ligaments :confused:
Watch this video.
Try to remember direction of the guide-needle on 1:24 min - from medial side to lateral. I saw this procedure a lot of time in operating room, and remembered in such manner I think.
It's not MRI, but for understanding may be useful.

Poliovirus mRNA lacks a 5' m7G cap but is translated efficiently by cellular ribosomes. Which of the following additional structural features of poliovirus mRNA is the most likely cause of its ability to be translated in the absence of a cap?
A) Absence of a 3' untranslated region (UTR)
B)Absence of a 5' UTR
C) Absence of a poly(A) tail
D) Presence of an internal ribosome entry site
E) Very short open reading frame
Answer is D.
Unlike the host cell's mRNAs the 5' end of poliovirus RNA is extremely long-over 700 nucleotides-and is highly structured. This region of the viral genome is called internal ribosome entry site (IRES) and it directs translation of the viral RNA. (http://en.wikipedia.org/wiki/Poliovirus).

An 8-year-old girl is brought to the physician for a well-child examination. Her mother says that she has been well except for an occasional cold. Her immunizations are up to date. She is at the 50th percentile for height and 60th percentile for weight. Physical examination shows breast bud development and a few pubic hairs. The mother asks whether her daughter's development is normal. Which of the following is the most appropriate initial response by the physician?
A) "I am concerned that your daughter may have precocious puberty."
B) "I think that your daughter is likely to begin menstruating in the next few months."
C) "I would like to order laboratory studies to ensure that your daughter's development is normal."
D) “Your daughter's breast development is somewhat less than might be expected for her age."
E) “Your daughter's development is normal."

Here we see Tanner-2 (10-11,5 y.o.), hypothyroidism(?)
i marked A its wrong..is it E?
