        shall consist of a separate account for each disease with 
        respect to which an amount is designated under section 6098, 
        and one account (to be known as the `Miscellaneous Account') 
        for amounts designated under section 6098 for which no disease

        as may be appropriated or credited to such account as provided 
        in this section or section 9602(b).
    ``(b) Transfers to Trust Fund.--There are hereby appropriated to 
each account within the Biomedical Research Fund amounts equivalent to 
the amounts designated under section 6098 for the disease with respect 
to which such account is established (or, in the case of the 
Miscellaneous Account, the amounts designated under section 6098 for 
which no disease is indicated).
    ``(c) Expenditures.--The Secretary of Health and Human Services 
shall distribute, as provided in appropriation Acts, amounts in the

any fiscal year for which the annual amount appropriated for the 
National Institutes of Health for biomedical research regarding the 
disease with respect to which the account is established is less than 
the amount so appropriated for the prior fiscal year.
    ``(e) Qualified Research.--For purposes of this section, the term 
`qualified research' means, with respect to any account of the

Institutes of Health regarding the disease with respect to which such 
account is established (or, in the case of the Miscellaneous Account, 
regarding any disease).''
