Methods for conducting dietary assessment in the United States date back to the early twentieth century. Methods of assessment encompassed dietary records, written and spoken dietary recalls, FFQ using pencil and paper and more recently computer and internet applications. Emerging innovations involve camera and mobile telephone technology to capture food and meal images. This paper describes si...

even when the effects of socioeconomic and behavioral factors—such as income, education, adequacy of prenatal care and harmful habits—are taken into account.5 In addition, despite the wide selection of safe and effective contraceptive methods and extensive dissemination of contraceptive information, unwanted pregnancy remains an important U. S. public health problem. More than half of the six m...

Biological vesicles are composed of a phospholipid membrane bi-layer, which has folded on itself to form a spherical structure with an aqueous cavity. We propose that synthetic vesicles, termed liposomes, composed of speciic species of phospholipids might provide a useful architecture for the execution of some existing algorithms for DNA based computation. In this model, the liposomes would ser...

Ginkgolides were always close to my heart. I continue to be strongly attracted to Ginkgo biloba, the ginkgolides and bilobalide. Starting in 1963, I became fascinated by these molecules while working on their isolation and structure elucidation in Sendai. Presumably, due to the ginkgolide studies, I received an invitation to join the faculty at Columbia University. After almost three decades of...

Numerous studies on cerebral angiography have been conducted since Egas Moniz's study in 1927. It is known that complications due to cerebral angiography are mainly resulted from the contrast medium. We have selected organic tri-iodide solution as a contrast medium because it is safe and offers a high contrast. Urografin (60% and 76%) were used in 1869 cerebral angiographies. Present studies we...

Optical absorption spectra of higher fullerenes (C70 and C76) as well as of C60 are calculated by a tight binding model with a long range Coulomb interaction. A reasonable parameter set gives calculated spectra which are in overall agreement with the experiments of of C60 and C70 in solutions. The variations of the spectral shape are discussed relating with the symmetry reduction going from C60...
