The Multiple Functions of Hemoglobin

Critical Reviews in Biochemistry and Molecular Biology, 1995
The aim of this review is to focus and discuss several parallel biological functions of hemoglobin besides its basic function of oxygen transport. In light of the information present in the literature the following possible physiological roles of hemoglobin are discussed: (1) hemoglobin as molecular heat transducer through its oxygenation-deoxygenation

The multiple functions of Numb

Experimental Cell Research, 2010
Numb is an evolutionary conserved protein that plays critical roles in cell fate determination. Mammalian Numb displays a higher degree of structural complexity compared to the Drosophila homolog based on the number of encoding genes (Numb and Numb-like) and of alternative spliced isoforms.

Functional MRI in Multiple Sclerosis

Journal of Neuroimaging, 2004
ABSTRACTThere is increasing evidence that the severity of the clinical manifestations of multiple sclerosis (MS) does not simply depend on the extent of tissue destruction, but rather represents a complex balance among tissue damage, tissue repair, and cortical reorganization.

Multiplication by Functions

2010
If X is an open subset of Rn, the function ψ belongs to \(C^\infty (X),\) and f is locally integrable on X, one has, for every test function \(\phi,\ ({\rm test}(\psi\ f))(\phi ) = ({\rm test}\ f)(\psi\ \phi ).\)
