The disclosure relates to compositions comprising a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with a) at least one hydrophobic group, and b) at least one hydrophilic group, wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, or poly alpha-1,3-1,6-glucan.

Amphiphilic polysaccharide derivatives and compositions comprising same

The invention pertains to a printing form and a process for preparing a polymeric printing form from a curable composition that includes a multifunctional urethane in a specified reactive group equivalent weight range, and an initiator. The process includes coating the curable composition onto a supporting substrate, such as a print cylinder, to form a layer, curing the layer with heat or by exposure to actinic radiation, and engraving the resulting cured layer to form at least one printing cell in the cured layer. The process prepares novel polymeric printing forms, particularly novel polymeric gravure printing forms, having a cured polymer-based composition layer that is engravable, resistant to solvent inks, and capable of printing gravure-quality images. The present invention shortens the time to prepare gravure printing cylinders and removes the need for and disposal of toxic heavy metals such as copper and chrome associated with conventional gravure print cylinder preparation.

A hydrogel tissue adhesive formed by reacting an aminated polysaccharide with a water-dispersible, aldehyde-functionalized multi-arm polyether is described. The hydrogel tissue adhesive may be useful as a general tissue adhesive and sealant for medical and veterinary applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, ophthalmic procedures, drug delivery, and to prevent post-surgical adhesions. Additionally, due to the presence of the aminated polysaccharide, the hydrogel tissue adhesive may also promote wound healing and blood coagulation, and provide antimicrobial properties.

Hydrogel tissue adhesive formed from aminated polysaccharide and aldehyde-functionalized multi-arm polyether

Disclosed herein are a kit and a method for forming a tissue coating that prevents undesired tissue-to-tissue adhesions resulting from trauma, surgery, infection, or other stimulus. The tissue coating is a hydrogel formed by reacting an aminocarboxymethyldextran containing primary amine groups with an oxidized carboxymethylcellulose containing aldehyde groups.

Tissue coating for preventing undesired tissue-to-tissue adhesions

A hydrogel tissue adhesive formed by reacting an aldehyde-functionalized polysaccharide containing pendant aldehyde groups with a water-dispersible, multi-arm amine is described. The hydrogel may be useful as a tissue adhesive or sealant for medical applications that require a more rapid degradation time, such as the prevention of undesired tissue-to tissue adhesions resulting from trauma or surgery.

Hydrogel tissue adhesive for medical use

This invention relates to dibenzothiopyran compounds. This invention also relates to layers and devices including at least one of these compounds.

Aromatic chalcogen compounds and their use

Novel aldehyde-functionalized polysaccharide compositions are described that are more stable in aqueous solution than oxidized polysaccharides or other types of polysaccharides containing pendant aldehyde groups. The aldehyde-functionalized polysaccharides may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.

Aldehyde-functionalized polysaccharides

Novel aldehyde-functionalized polysaccharide compositions containing pendant dialdehyde groups are described that are more stable in aqueous solution than oxidized polysaccharides. The aldehyde-functionalized polysaccharides may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.

The present disclosure relates to organometallic complexes and electronic devices containing the complexes. The complexes have the formula MYZ, where n is 1, 2, or 3; M is a metal in a +2, +3, or +4 oxidation state, Y is selected from an 8-hydroxyquinolate and a substituted 8-hydroxyquinolate, and Z is a phenolate. At least one Y is a substituted 8-hydroxyquinolate having the formula 

Organometallic complexes

The present invention relates to tris(N-aryl-benzimidazole)benzene compounds of the formula: where R-R, Ar, m, n, p, q, r, and s are defined in the specification. Also provided are compositions comprising tris(N-aryl-benzimidazole)benzene compounds. The invention also relates to use of such compounds in electronic devices.
