Kidney development branches out
(John Wiley & Sons, Inc., 1999)
For more than 40 years now, the developing kidney has served as a model paradigm for epithelial-mesenchymal interactions. The principles of inductive signaling, epithelial cell differentiation, and pattern formation are ...
Fermi-liquid-type spectral function and angle resolved photoelectron spectra of the Ti-3dz2-band of TiTe2
(Elsevier, 1994-05-06)
Angle and temperature dependent photoelectron spectra with high energy and momentum resolution ([Delta]E = 300meV, [Delta][theta]Eb eV) of the quasi-two-dimensional, metallic layer compound TiTe2 along the direction . The ...
Antibody-antigen complex formation with immobilized immunoglobulins
(Elsevier, 1992-08-15)
We have investigated the complex formation between an immobilized monoclonal antibody and antigens that differ in size about 50-fold. As a model system, we used an iodinated progesterone derivative and a progesterone-horseradish ...
Preparation of polyfunctional diorganomercurials and their transmetallation to diorganozincs. Applications to the preparation of optically active secon
(Elsevier, 1992-10-13)
Two new methods of preparation of functionalized diorganomercurials have been developed. The first method involves a substitution reaction of (ICH2 Their transmetallation with zinc dust (toluene, 80[deg]C, 3-5 h) affords ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Defect interactions on solid surfaces
(Elsevier, 1993-03-10)
A unified approach to the calculation of the elastic interaction between defects on a surface that describe, for example, steps, islands, and stress domains is presented. This is accomplished by determining the spatial ...
Genotypes with the apolipoprotein ε4 allele are predictors of coronary heart disease mortality in a longitudinal study of elderly Finnish men
(Springer-Verlag, 1996-05)
Earlier we reported that allelic variation in the gene coding for apolipoprotein (apoE) is a significant predictor of variation in the risk of coronary heart disease (CHD) death in a longitudinal study of elderly Finnish ...
Hydrodesulfurization over model sulfide cluster-derived catalysts
(Elsevier, 1991)
There is growing interest in the use of organometallic clusters as precursors to model heterogeneous catalysts. This interest is partially derived from the expectation that "solid-state metal complex catalysts" will be ...
Hydrogen peroxide production using chemically treated Pichia pastoris cells
(Elsevier, 1994-01)
A new method has been developed to prepare intact cell systems to produce hydrogen peroxide (H2O2) using methylotrophic yeast Pichia pastoris. The high alcohol oxidase (EC 1.1.3.13; AOXase) content in the living P. pastoris ...
