Abstract: The present invention relates to methods for increasing absorption of compounds of interest by nematode worms through the design of carrier systems containing said compound of interest and expressing chemoattractive tags at their surface.

Abstract: An aerolysin nanopore or a nanotube is used for the electrical detection of peptides, proteins separated by at least one amino acid and other macromolecules such as polysaccharides or synthetic or natural polymers present in a preparation where said nanopore or nanotube is inserted into a lipid membrane which is subjected to a difference in potential greater than ?160 mV, in a reaction medium having an alkali metal halide electrolyte solution with a concentration of less than 6M and at a temperature of less than 40° C., and where said use is intended to differentiate said peptides, proteins and other molecules according to their length and their mass. Application to the sequencing of peptides and other molecules to differentiate them according to their length and mass with an amino acid-level or monomer-level resolution and to medical diagnosis.

Abstract: The present invention concerns a polypeptide comprising the N-terminal fragment of a cystatin, and/or a cystatin expression inducer for use for the treatment of sterility and/or infertility, and a method of diagnosing and/or predicting sterility and/or infertility of a subject and/or of a couple of subjects, which method comprises measuring the level of at least one cystatin in a biological sample of a male subject and/or measuring the level of at least one cystatin in a biological sample of a female subject, and optionally measuring further the level of at least one cathepsin in a biological sample of said male of female subject.

Abstract: In one aspect, the present invention concerns methods and kits for quantifying a target nucleic acid in a sample. In embodiments, a method comprises sequestrating the target nucleic acid by one or more interactors to form a sequestered conjugate that will be further labeled to form a labeled conjugate. The signal produced by the labeled conjugate is measured and correlated to the amount of the target nucleic acid. In another aspect, the present invention concerns a method for quantifying a target nucleic acid in a sample by a reaction of the nucleic acids in the sample with a nucleic acid interactor or set of interactors to form a conjugate. The conjugate is then sequestered from the rest of the sample with a molecule bound to a support, to form a sequestered conjugate. The sequestered conjugate is labeled to form a labeled conjugate. The signal produced by the labeled conjugate is measured and correlated to the amount of the target nucleic acid.

Abstract: The invention provides a novel PF4 pharmacophore that is useful, inter alia, for identifying peptidomimetics and other compounds capable of modulating PF4 activity (e.g., as inhibitors, agonists or antagonists). Mutant PF4 polypeptide sequences are also provided that modulate PF4 activity in cells.
