Abstract: The present invention relates to probiotic compositions and kits thereof, comprising live bacteria belonging to the natural flora of the human body cavity such as intestine and vaginal tract, in particular, strains of lactobacillus or bifidobacterium species, and low molecular-weight non-proteinaceous iron chelators capable of lowering the iron concentration over the whole physiological pH-range of relevance to levels that inhibit growth of pathogens, but which allow for the growth of the bacteria of the composition.

Abstract: A new class of polychelants, their chelates with metal ions and their physiologically acceptable salts, useful, either as they are or in association or formulation with other components, for diagnostic imaging as general or specific contrast agents for specific tissues, organs or body compartments.

Abstract: A process for the preparation of macromolecular chelants characterized by a high content in chelant groups per macromolecule.

Abstract: The present invention refers to pharmaceutical and diet formulations for the prophylaxis and treatment of gastrointestinal disorders.

Abstract: A new class of branched dendrimeric macromolecules, is described essentially consisting of a polyvalent central nucleus and a series of polyoxaalkylene "dendra". Such molecules are characterized by the presence of at least one branch, attached either directly to the "core" or to a "dendron", which does not participate in the growth and which therefore differs from all the other functions of the macromolecule.

Abstract: Branched, dendrimeric macromolecules having a central nucleus and a series of polyoxaalkylene chains that radiate from the nucleus and spread into the surrounding space branching a cascade fashion until the desired size results. Molecules formed in this manner are free of excessive functional crowding on their outer surfaces. Synthetic methods of preparing these molecules and their uses are described.

Abstract: Branched, dendrimeric-type macromolecules composed essentially of a central nucleus and of a series of polyoxaalkyl chains that depart from said nucleus and spread into the surrounding space branching in a cascade fashion useful as carriers of drugs, contrast agents, etc.

Abstract: The present invention concerns Lactobacillus strains and pharmaceutical compositions containing them.

Abstract: The present invention concerns the use of dendrimeric-type branched macromolecules, comprising polyoxaalkylene chains, as catalysts or coadjuvants of phase transfer catalysis reactions.
