    Mast cell diseases, like Mastocytosis, occur when the body has an excessive amount of mast cells. Due to the amount of mast cells in a person with Mastocytosis' body, they can get very sick and experience symptoms such as skin rashes, nausea, vomiting, headaches, bone pain and skeletal lesions, and anaphylaxis. The mast cells can be triggered by heat, cold, perfumes, medicines, and insect bites.

      I wonder...do these cells disappear or decompose? What might the long-term effects of adding such cells do to your body?
  • Researchers have reduced blood alcohol levels in intoxicated mice by injecting them with nanocapsules containing enzymes that are instrumental in alcohol metabolism. The treatment demonstrates a novel drug delivery technology that could have broad medical applications.

How can a mutation in the DNA occur - 1 views

shared by Day Hop on 26 Mar 12 - No Cached
  • Mutations can be inherited. This means that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children. 2) Mutations can be acquired. This happens when environmental agents damage DNA, or when mistakes occur when a cell copies its DNA prior to cell division.

  • whether Einstein started off with a special brain that predisposed him to be a great physicist, or whether doing great physics caused certain parts of his brain to expand

Understanding General Canine Genetics - 0 views

  • In the dog, there are 78 chromosomes existing of 39 matched pairs which make up the dog’s “genotype”. On the other hand, the dog’s “phenotype” is what the animal actually looks like and this can be influenced by both environmental and developmental factors. For example, a dog’s adult size is partially determined by his genotype but is also influenced by such factors as health and nutrition as a puppy.

      Dog size depends on the dog's "phenotype". This is influenced by both environmental and developments factors. Such as the heath and the way the dog grew up.
