On the origin of light-induced changes in the proton magnetic relaxation rate of chloroplast thylakoid membrane suspensions
(Elsevier, 1981-03)
The spin-lattice relaxation rate of solvent protons in suspensions of chloroplast thylakoid membranes undergoes a large transient depression following illumination in white light. This change appears to require the presence ...
Optical errors in a liquid chromatography absorbance cell
(Elsevier, 1988)
The shadowgraph method is used to visualize mobile phase flow through a liquid chromatography absorbance cell with "Z" flow geometry. It is shown thatmixing is incomplete in the cell. Composition gradients persist throughout ...
Synthesis of high-affinity, hydrophobic monosaccharide derivatives and study of their interaction with concanavalin A, the pea, the lentil, and fava bean lectins
(Elsevier, 1992-12)
Concanavalin A (Con A) and agglutinins from the pea (PSA), lentil (LCH), and fava bean (VFA) constitute a group of -mannose/-glucose binding legume lectins. In addition to their sugar binding specificity, these lectins ...
Solid phase enzyme-linked competitive binding assay for riboflavin
(Elsevier, 1988-01)
A new solid-phase enzyme-linked assay for riboflavin (vitamin B2) is described. The assay is based on the competition between analyte vitamin molecules and a glucose-6-phosphate dehydrogenase-3-carboxymethylriboflavin ...
Synthesis of 1-(2-aminopropyl)benzimidazoles, structurally related to the TIBO derivative R82150, with activity against human immunodeficiency virus.
(Elsevier, 1993-04)
A number of 1-(2-aminopropyl)-2-mercaptobenzimidazoles related to the TIBO derivatives R82150 have been prepared and tested for their activity against human immunodeficiency virus type 1 (HIV-1). These compounds were all ...
Prostate Carcinoma Skeletal Metastases: Cross-talk between Tumor and Bone
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-12)
The majority of men with progressive prostate cancer develop metastases with the skeleton being the most prevalent metastatic site. Unlike many other tumors that metastasize to bone and form osteolytic lesions, prostate ...
