  • Publication number: 20110229918
    Abstract: The invention relates to a precursor for producing sintered metallic components, a method for producing the precursor and the production of the components. The object of the invention is to disclose possibilities of being able to produce sintered metallic components, which render possible an increased physical density and a reduced shrinkage on the fully sintered component. With a precursor according to the invention for the production of sintered metallic components, a coating layer is formed on a core, which is formed from respectively one particle of a first metallic powder. The coating layer is formed with a second powder and a binder. The first powder thereby has a particle size d90 of at least 50 ?m and the second powder has a particle size d90 of less than 25 ?m. The precursor is powdery.

    Abstract: Anti-herpetic material such as 2-amino purine derivatives to prevent or treat autoimmune disease or a disease originating from an abnormal functioning of the sympathetic chain in a human subject. The disease is often of a tissue or organ associated with decreased blood flow to the tissue or organ (correlated with hypertonicity of the vessels feeding the tissue or organ). The treatment reduces inflammation, scarring, destruction, and pain in the tissue or organ affected and returns the tissue or organ to nearly normal functioning, while showing none of the side effects of previous treatments. Prolonged use of the anti-herpetic compounds reduces prodrome, vesicle formation and viral shedding. The anti-herpetic compounds may be administered alone or in combination with a compound that reduces the rate of renal excretion of the anti-herpetic compound. The anti-herpetic compounds are particularly useful when administered at a level equivalent in activity to 250 mg/kg famciclovir per day.

  • Publication number: 20110014196
    Abstract: The invention relates to compounds comprising a plurality of enzyme substrates suitably linked and further carrying one or more cargo entities. In particular such compounds have the structure (substrate)n-linker-(cargo)m wherein “substrate” is a substrate specific for an enzyme-type protein; n is 2 or more; “linker” is a linking unit consisting of 1 to 300 atoms; “cargo” is a drug, a label detectable by a fluorescence detector, magnetic resonance imaging (MRI), positron emission tomography (PET) or scintigraphy, or a functional group which can be transformed into a drug or a detectable label; and m is 1 or more. The invention further relates to a corresponding molecular shuttles having the structure (fusion protein)n-linker-(cargo)m wherein “fusion protein” is a proteinaceous binding entity fused to an enzyme-type protein for which specific substrates exist. The proteinaceous binding entity is designed to bind to a target structure in vitro or in vivo, for example a cellular receptor.

  • Publication number: 20110009607
    Abstract: The present invention provides a method for preparing a DNA fragment, in which a desired double-stranded DNA fragment having a sticky end is directly and easily obtained from an amplification product (an amplified fragment) after PCR without a restriction enzyme digestion. The method for preparing a DNA fragment having a sticky end of the present invention comprises: (i) a step of performing a PCR reaction using a template DNA and specific primers to obtain an amplified DNA fragment; and (ii) a step of performing a prescribed treatment on the amplified DNA fragment to dissociate a protecting group from the fragment.
