We used vesicular stomatitis virus to test the effect of complementation on the relative fitness of a deleterious mutant, monoclonal antibody-resistant mutant (MARM) N, in competition with its wild-type ancestor. We carried out competitions of MARM N and wild-type populations at different multiplicities of infection (MOIs) and initial ratios of the wild(More)
We compared, using a combination of different immunological methods and by competitive PCR, the expression of the alpha2-macroglobulin receptor/low-density lipoprotein receptor-related protein (alpha2-M-R/LRP) in human keratinocytes and fibroblasts. This receptor has previously been found in skin only in dermal cells associated with fibroblasts and(More)
Src-family kinase expression was measured in 52 human mammary tumor (T) specimens compared with non-tumor (NT) tissue from the same patient by enzymatic assays employing a Src-kinase family-specific peptide substrate and by immunoblotting with an antibody recognizing the Src-family kinases Src, Fyn, and Yes. In the T specimens, the mean enzymatic activity(More)
RNA viruses are widely used to study evolution experimentally. Many standard protocols of virus propagation and competition are done at nominally low multiplicity of infection (m.o.i.), but lead during one passage to two or more rounds of infection, of which the later ones are at high m.o.i. Here, we develop a model of the competition between wild type (wt)(More)
Reconstructed human skin was prepared from human keratinoblasts. After 1 week of cultivation at the air-liquid interface a stratified layer developed, similar to native human epidermis. Liposomes with an average diameter of 50 nm, made of phosphatidylcholine (PC), phosphatidylserine (PS) and human stratum corneum lipids (hSCL) were applied on top of this(More)
In this paper is described by histochemical, polarization optical and electron microscopical techniques resp. an up to now unknown protein structure in the basal plasmoditrophoblast of the human placenta. This structure consists of noncollagenic filaments containing cystin or cystein. They are arranged in the plain in the form of a network and parallel to(More)
Inflammation plays an important role in both the initiation of atherosclerosis and development of atherothrombotic events. The adherence of leukocytes/monocytes to the endothelium is an early event in atherogenesis. Phytotherapeutica as garlic and garlic extracts were shown to have beneficial modulating effects in patients with atherosclerotic disease. The(More)
