Abstract: A method of facilitating the delivery of an agent across the blood-brain barrier (BBB) of a subject, the method involving the use of a low dose of vascular endothelial growth factor (VEGF) polypeptide. In some embodiments, the VEGF polypeptide can be given to the subject before and after administration of the agent at multiple doses.

Abstract: A drug delivery system and methods of using such for delivering a peglyated therapeutic agent to heart.

Abstract: Disclosed herein is a method of facilitating the delivery of an agent across blood-brain barrier (BBB) of a subject. The method includes administering to the subject in sequence or concomitantly, an effective amount of a growth factor selected from the group consisting of, vascular endothelial growth factor (VEGF), insulin-like growth factor I (IGF-1), IGF-II, a portion thereof and a combination thereof; and an agent that is any of a therapeutic agent or an imaging agent. The administered amount of the growth factor is capable of transiently increasing BBB permeability of the subject and thereby allowing the agent to be delivered across BBB. Also disclosed herein is a method of treating a subject suffering from a brain tumor, a brain stroke, a neuropsychiatric disorder and/or a neurodegenerative disease.

Abstract: Disclosed herein is a multiple drugs delivery system and its uses in treating diseases. The multiple drugs delivery system includes, an anti-PEG antibody for directing the PEGylated therapeutic to the treatment site; and a hydrogel for retaining the anti-PEG antibody and/or the PEGylated therapeutic at the treatment site for at least 3 days. The hydrogel is selected from the group consisting of hyaluronan (HA) or a derivative of HA, collagen, gelatin, fibronectin, fibrinogen, alginate, chitosan, and a synthetic biocompatible polymer. The anti-PEG antibody and the hydrogel are present in the mixture in a ratio from about 1:1 (v/v) to 1:100 (v/v). At least two dosages of the PEGylated therapeutic, which may be the same or different, are administered to the subject, with each dosage being given at about 1 hour to about 1 week apart. Accordingly, a novel method of treating a subject having cancer or ischemia disease is also provided.

Abstract: Proteo-microparticles such as proteoliposomes comprising a microparticle (e.g., a liposome) and platelet membrane proteins, wherein the proteo-microparticles are capable of binding to monocytes, neutrophils, or other circulating blood cells capable of migrating to an injured site. Also provided herein are uses of the proteoliposomes for delivering a therapeutic agent via monocytes to an injured site.

Abstract: A combination of active agents selected from a FoxM1 enhancer, an Id1 enhancer, and a JNK3 inhibitor and the uses thereof in promoting cardiomyocyte proliferation and treating heart diseases in a subject in need of the treatment.

Abstract: Disclosed herein are a method and a kit for making a diagnosis as to whether a subject suffers from myocardial infarction (MI). The method and the kit can accurately and efficiently identify the MI patient through detecting the circulating let-7a and let-7f, both of which are highly expressed in healthy subject, and downregulated in MI patient. According to the present method and kit, the MI patient is capable of receiving a proper treatment in time.
