DIRECTLY COMPRESSIBLE POLYVINYL ALCOHOLS
The present invention relates to directly compressible co-mixtures for the production of tablets having delayed release of active compound which comprise polyvinyl alcohols (PVAs) and microcrystalline celluloses (MCCs). The invention also relates to a process for the preparation of corresponding directly compressible co-mixture
COMPOSITE MATERIALS
A composite material is formed by combining an expandable polymer having a charge with another polymer having an opposite charge to produce. In particular, the composite material can be prepared by combining the polymers with a medium such as and water, and expanding the mixture using a treatment that expands the mixture to produce, for example, insoluble porous foam-like composites.
ENZYMATIC SYNTHESIS OF SOLUBLE GLUCAN FIBER
An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.
Manufacturing process for polysaccharide beads
The invention discloses a method of manufacturing polysaccharide beads, comprising the steps of: i) providing a water phase comprising an aqueous solution of a polysaccharide; ii) providing an oil phase comprising at least one water-immiscible organic solvent and at least one oil-soluble emulsifier; iii) emulsifying the water phase in the oil phase to form a water-in-oil (w/o) emulsion; and iv) inducing solidification of the water phase in the w/o emulsion, wherein the organic solvent is an aliphatic or alicyclic ketone or ether.
RESIN MOLDED ARTICLE
The present invention pertains to a resin formed article obtained by forming a resin composition that comprises a cycloolefin resin and a styrene-based thermoplastic elastomer, the styrene-based thermoplastic elastomer having a weight average molecular weight of 20,000 to 150,000, and having a difference in refractive index (ΔnD) of more than −0.002 to less than +0.002 with respect to the cycloolefin resin, the resin composition having a residual ratio of 0.10 wt % or less when analyzed based on the residue on ignition test method specified in the Japanese Pharmacopeia, the resin composition having a light transmittance (optical path length: 3 mm) of 55% or more with respect to light having a wavelength of 450 nm when the resin composition is formed in a shape of a sheet having a thickness of 3.0 mm, and subjected to light transmittance measurement, and the resin composition having a Charpy impact strength of 5 to 40 kJ/m.sup.2 when the resin composition is formed to have a thickness of 4.0 mm, a length of 80.0 mm, and a width of 10.0 mm, and subjected to the notched Charpy impact test specified in JIS K 7111-1 at 23° C.

Protein-polymer-drug conjugates
A drug conjugate is provided herein. The conjugate comprises a protein based recognition-molecule (PBRM) and a polymeric carrier substituted with one or more -L.sup.D-D, the protein based recognition-molecule being connected to the polymeric carrier by L.sup.P. Each occurrence of D is independently a therapeutic agent having a molecular weight ≦5 kDa. L.sup.D and L.sup.P are linkers connecting the therapeutic agent and PBRM to the polymeric carrier respectively. Also disclosed are polymeric scaffolds useful for conjugating with a PBRM to form a polymer-drug-PBRM conjugate described herein, compositions comprising the conjugates, methods of their preparation, and methods of treating various disorders with the conjugates or their compositions.
Residence structures and related methods
Residence structures, systems, and related methods are generally provided. Certain embodiments comprise administering (e.g., orally) a residence structure to a subject (e.g., a patient) such that the residence structure is retained at a location internal to the subject for a particular amount of time (e.g., at least about 24 hours) before being released. The residence structure may be, in some cases, a gastric residence structure. In some embodiments, the structures and systems described herein comprise one or more materials configured for high levels of active substances (e.g., a therapeutic agent) loading, high active substance and/or structure stability in acidic environments, mechanical flexibility and strength in an internal orifice (e.g., gastric cavity), easy passage through the GI tract until delivery to at a desired internal orifice (e.g., gastric cavity), and/or rapid dissolution/degradation in a physiological environment (e.g., intestinal environment) and/or in response to a chemical stimulant (e.g., ingestion of a solution that induces rapid dissolution/degradation). In certain embodiments, the structure has a modular design, combining a material configured for controlled release of therapeutic, diagnostic, and/or enhancement agents with a structural material necessary for gastric residence but configured for controlled and/or tunable degradation/dissolution to determine the time at which retention shape integrity is lost and the structure passes out of the gastric cavity. For example, in certain embodiments, the residence structure comprises a first elastic component, a second component configured to release an active substance (e.g., a therapeutic agent), and, optionally, a linker. In some such embodiments, the linker may be configured to degrade such that the residence structure breaks apart and is released from the location internally of the subject after a predetermined amount of time.
