Is bone equally responsive to calcium and vitamin D intake from food vs. supplements? Use of 41calcium tracer kinetic model

Autor: Tara S. Rogers, Marjorie G. Garrod, Janet M. Peerson, Darren J. Hillegonds, Bruce A. Buchholz, Elieke Demmer, Christine Richardson, Erik R. Gertz, Marta D. Van Loan

Publikováno v: Bone Reports, Vol 5, Iss , Pp 117-123 (2016)

Background: Few interventions directly compare equivalent calcium and vitamin D from dairy vs. supplements on the same bone outcomes. The radioisotope calcium-41 (41Ca) holds promise as a tracer method to directly measure changes in bone resorption w

Traditionally, the bioavailability of vitamin B-12 (B12) from in vivo labeled foods was determined by labeling the vitamin with radiocobalt (57Co, 58Co or 60Co). This required use of penetrating radioactivity and sometimes used higher doses of B12 th

Transcobalamin C776G genotype modifies the association between vitamin B12 and homocysteine in older Hispanics

Autor: Joshua W. Miller, Ralph Green, Marjorie G. Garrod, Lindsay H. Allen, Mary N. Haan

Publikováno v: European journal of clinical nutrition

Background A common polymorphism, C776G, in the plasma B12 transport protein transcobalamin (TC), encodes for either proline or arginine at codon 259. This polymorphism may affect the affinity of TC for B12 and subsequent delivery of B12 to tissues.

Fraction of Total Plasma Vitamin B12 Bound to Transcobalamin Correlates with Cognitive Function in Elderly Latinos with Depressive Symptoms

Autor: Mary N. Haan, Ralph Green, William J. Jagust, Joshua W. Miller, Dan M Mungas, Marjorie G. Garrod, Lindsay H. Allen

Publikováno v: Clinical Chemistry. 54:1210-1217

Background: The fraction of total plasma vitamin B12 bound to transcobalamin (holoTC/B12 ratio) may reflect tissue levels of the vitamin, but its clinical relevance is unclear. Methods: We assessed associations between cognitive function and total B1

Measurement of Total Vitamin B12 and Holotranscobalamin, Singly and in Combination, in Screening for Metabolic Vitamin B12 Deficiency

Autor: Marjorie G. Garrod, Alan L. Rockwood, Mark M. Kushnir, Joshua W. Miller, Ralph Green, Mary N. Haan, Lindsay H. Allen

Publikováno v: Clinical Chemistry. 52:278-285

Background: The standard screening test for vitamin B12 deficiency, measurement of total plasma vitamin B12, has limitations of sensitivity and specificity. Plasma vitamin B12 bound to transcobalamin (holoTC) is the fraction of total vitamin B12 avai

Metabolic evidence of vitamin B-12 deficiency, including high homocysteine and methylmalonic acid and low holotranscobalamin, is more pronounced in older adults with elevated plasma folate123

Autor: Ralph Green, Mary N. Haan, Joshua W. Miller, Lindsay H. Allen, Marjorie G. Garrod

Background: An analysis of data from the National Health and Nutrition Examination Survey indicated that in older adults exposed to folic acid fortification, the combination of low serum vitamin B-12 and elevated folate is associated with higher conc
