Disclosed herein are crosslinked chondroitin sulfate particles crosslinked chondroitin sulfate particle polyelectrolytes. The particles are useful in drug delivery applications. The particles may be used to treat various conditions, including bacterial and fungal infections.

Filmogenic compositions are described for topical anaesthetic bioadhesives (TABs) comprising a) a xanthan biopolymer matrix selected from Xanthomonas species and pathovars, including Xanthomonas campestris pathovars campestris and maninhotis, and Xanthomonas arboricola pathovar pruni, a producer of pruni xanthan, wherein the matrix is made of pure or combined xanthan varieties in any proportion, said matrix comprising between 1% and 95% by weight of the total weight of the composition, and additives or excipients; b) at least one anaesthetic, in a proportion of 0.1% to 50% by weight of the total weight of the composition. The topical anaesthetic bioadhesives (TABs) are also described, and they may be applied to the gingival mucosa and/or alveolar mucosa on the buccal (1) or lingual/buccal (2) surfaces with extensions and anatomical contours for crowns of the upper and lower dental arches.

Provided is a peptide for targeting colorectal cancer, a composition for diagnosing radioresponsiveness-dependent prognosis of colorectal cancer using the peptide, and a drug delivery use of the peptide, wherein a functional peptide capable of targeting cancer has been discovered so as to implement personalized diagnosis and treatment for individual patients having cancer, in consideration of problems occurring during treatment in which treatment cases of respective patients differ due to different therapeutic responses resulting from genetic differences in the individual patients.

Disclosed herein are methods and compositions for making vault particles in yeast hosts and yeast vaults produced therefrom.

Described herein is the use of rabbit hybridoma technology, along with a panel of truncated mesothelin domain fragments, to identify anti-mesothelin mAbs that bind specific regions of mesothelin. In one aspect of the present disclosure, the rabbit mAbs bind an epitope that is not part of Region I. In particular, the identified mAbs (YP187, YP223, YP218 and YP3) bind either Region II (391-486), Region III (487-581) or a native conformation of mesothelin with subnanomolar affinity. These antibodies do not compete for binding with the mesothelin-specific immunotoxin SS1P or mesothelin-specific antibody MORAb-009. In another aspect, disclosed is a high-affinity rabbit mAb that binds Region I of mesothelin (YP158). YP158 binds native mesothelin protein in cancer cells and tissues with high affinity and specificity.

The invention relates to novel conjugating reagents capable of reaction with at least one nucleophile present in a peptide or protein, which contain at least one leaving group which is lost on reaction with said nucleophile, in which the leaving group includes a portion —(CH.sub.2CH.sub.2O).sub.n—, in which n is a number of six or more; and novel processes for the preparation of conjugates containing peptides or proteins made using such reagents.

The invention relates to a microsphere composition comprising (a) a microsphere material; and (b) a lipidic liquid formulation comprising (i) an effective amount of a progestogen, and (ii) vitamin E or an analog of vitamin E, incorporated within said microsphere material, into said microspheres. The composition may be used to manage and control the synchronization of estrus in animals.

Methods, compositions, and systems for treating ischemia-associated and other ocular conditions using cartilage oligo matrix protein-Angiopoietin 1 (COMP-Ang1) are disclosed and described.

Provided are knottin-drug conjugates. The conjugates include a knottin peptide that includes an engineered loop that binds to a target on a cancer cell surface, and a drug (e.g., a nucleoside drug) conjugated to the knottin peptide through a linker. Also provided are pharmaceutical compositions and kits that include the knottin-drug conjugates, as well as methods of using the knottin-drug conjugates, e.g., for therapeutic purposes.
