Surface-active agents are also known as surfactants.

Compositions and methods for use in three dimensional model printing

Compositions for use in the manufacture of three-dimensional objects including compositions for use as a support and / or release material in the manufacture of the three-dimensional objects are provided. There is thus provided, in accordance with an embodiment of the present invention, a composition suitable for building a three-dimensional object. The compositions may include, inter alia, a curable component, having a functional group, wherein if the functional group is a polymerizable reactive functional group, then the functional group is a (meth)acrylic functional group, a photo-initiator, a surface-active agent and a stabilizer; wherein said composition has a first viscosity of about 50–500 cps at a first temperature, wherein said first temperature is ambient temperature, and a second viscosity lower than 20 cps at a second temperature wherein said second temperature is higher than said first temperature, wherein, after curing, the composition results in a solid form. There is thus provided, in accordance with another embodiment of the present invention, a composition suitable for support in building a three-dimensional object. The compositions may include, inter alia: a non-curable component, a curable component, wherein the non-curable component is not reactive with said curable component, a surface-active agent and a stabilizer; wherein said composition has a first viscosity of about 20–500 cps at a first temperature, wherein said first temperature is ambient temperature, and a second viscosity lower than 20 cps at a second temperature wherein said second temperature is higher than said first temperature, wherein, after irradiation, the composition results in a solid, a semi-solid or liquid material. A method for the preparation of a three-dimensional object by three-dimensional printing is provided in accordance with embodiments of the present invention. Embodiments of the present invention further provide a three-dimensional object prepared according to the methods of the invention.

Compositions, formulations and kit with anti-sense oligonucleotide and anti-inflammatory steroid and/or obiquinone for treatment of respiratory and lung disesase

A pharmaceutical composition and formulations comprise preventative, prophylactic or therapeutic amounts of an oligo(s) anti-sense to a specific gene(s) or its corresponding mRNA(s), and a glucocorticoid and/or non-glucocorticoid steroid or a ubiquinone or their salts. The agents, composition and formulations are used for treatment of ailments associated with impaired respiration, bronchoconstriction, lung allergy(ies) or inflammation, and abnormal levels of adenosine, adenosine receptors, sensitivity to adenosine, lung surfactant and ubiquinone, such as pulmonary fibrosis, vasoconstriction, inflammation, allergies, allergic rhinitis, asthma, impeded respiration, lung pain, cystic fibrosis, bronchoconstriction, COPD, RDS, ARDS, cancer, and others. The present treatment is effectively administered by itself for conditions without known therapies, as a substitute for therapies exhibiting undesirable side effects, or in combination with other treatments, e.g. before, during and after other respiratory system therapies, radiation, chemotherapy, antibody therapy and surgery, among others. Each of the agents of this invention may be administered directly into the respiratory system so that they gain direct access to the lungs, or by other effective routes of administration. A kit comprises a delivery device, the agents and instructions for its use.

The present invention relates to a foamable therapeutic composition comprising: (a) a therapeutically effective concentration of at least one active agent selected from the group consisting of a channel agent, a cholinergic agent, and a nitric oxide donor; and (b) a foamable carrier comprising:
    • i. about 50% to about 98% of a solvent selected from the group consisting of water; a hydrophilic solvent; a hydrophobic solvent; a potent solvent; a polar solvent, a silicone, an emollient, and mixtures thereof;
    • ii. 0% to about 48% of a secondary solvent selected from the group consisting of water; a hydrophilic solvent; a hydrophobic solvent; a potent solvent; a polar solvent, a silicone, an emollient, a co-solvent, a penetration enhancer and mixtures thereof;
    • iii. a surface-active agent;
    • iv. about 0% to about 5% by weight of at least one polymeric agent; and
    • v. a liquefied or compressed gas propellant at a concentration of about 3% to about 25% by weight of the total composition;
    • wherein the composition is housed in a container and is substantially flowable, and
    • which upon release expands to form a breakable foam; and
    • wherein the foamable carrier is selected to generate a foam of good to excellent quality.
The invention further provides a method of treating, alleviating or preventing a disorder of mammalian subject, comprising administering such a composition to an afflicted target site.
