Answer to Question 1

If serum B12 levels are measured, they do not reveal the amount of B12 on a tissue level. Serum B12 could be normal with a low tissue level. Methylmalonic, a metabolite in the B12 pathway is a more accurate indicator of B12 on the tissue level.

Answer to Question 2

This should be done in a schematic format and should include the pathways involving homocysteine conversion and illustrating where the B vitamins are involved. These pathways are available in basic biochemistry texts and most advanced nutrition texts.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
