Abstract: Specific drug delivery to tumor cells without affecting normal cells is a major challenge in cancer treatment. The present invention incorporates embedding nonionic surfactant vesicles (niosomes) containing an anti-cancer therapeutic agent with chlorotoxin into a thermosensitive chitosan hydrogel network. Chitosan has mucoadhesive property which can be used in the targeting of the tumor cells with the mucin over expression. Chlorotoxin is a 36 amino acid peptide obtained from Leiurus quinquestriatus scorpion venom which binds preferentially to tumor cells of neuroectodermal origin but not to normal cells. The incorporation of chlorotoxin along with niosomes in the chitosan hydrogel is used as the second targeting strategy to further improve the specific delivery of drugs to tumor cells such as glioma.

Abstract: The invention provides novel guanylate cyclase-C agonist peptides and their use in the treatment of human diseases including gastrointestinal disorders, inflammation or cancer (e.g., a gastrointestinal cancer). The peptides can be administered either alone or in combination with an inhibitor of cGMP-dependent phosphodiesterase. The gastrointestinal disorder may be classified as either irritable bowel syndrome, constipation, or excessive acidity etc. The gastrointestinal disease may be classified as either inflammatory bowel disease or other GI condition including Crohn's disease and ulcerative colitis, and cancer.
Abstract: The present invention provides a therapeutic agent, a treatment method and an inspection method for diseases caused by activation of neutrophils. More specifically, the invention relates to a neutrophil activation regulator which comprising a histidine-rich glycoprotein (HRG) as an active ingredient, and provides a therapeutic agent for diseases caused by neutrophil activation comprising the neutrophil activation regulator, a treatment method for diseases caused by neutrophil activation, and further an inspection method for diseases caused by neutrophil activation. The present invention is based on the neutrophil activation regulator including the HRG as an active ingredient. The present invention extends to the depressant agent for neutrophil-vascular endothelial cell interaction including the HRG of the present invention as an active ingredient, the treatment method for diseases caused by neutrophil activation and/or inflammatory diseases accompanied by neutrophil activation.

Abstract: The present invention provides embodiments which involve methods of providing a predetermined concentration of thymosin beta 4 (TB4) at a predetermined time, t, in a body portion of a live human patient. The methods can include determining a thymosin beta 4 treatment dosage (D) using Formula I: C=(A)D·t?B, wherein C is the predetermined concentration at time t, in ng/mL, D is the dosage of thymosin beta 4 administered in mg, t is the time elapsed after administration of dosage D in hours, A is about 30 to about 38, and B is about 0.5 to about 1; and administering the dosage (D) of thymosin beta 4 to the patient. Formula I may be, for example, C=(35.6)D·t?0.754??(Formula II).
