Abstract: Generally, the present invention relates to the use of folic acid and folate modification in inducing B-cell immune tolerance and targeting mIgM-positively-expressed B-cell lymphoma. The present invention also relates to a method, a pharmaceutical composition and a combination for inducing B-cell immune tolerance and for targeting mIgM-positively-expressed B-cell lymphoma.

Abstract: Compositions and methods for administration of local anesthetics that are delivered by a single injection and enable repeated on-demand or high influx analgesia over extended periods have been developed. Pharmaceutical compositions including an effective amount of one or more sodium channel blockers including site 1 sodium channel blockers, optionally one or more alpha-2-adrenergic agonists, which are optionally encapsulated in liposomes, particles or microbubbles, and one or more triggerable elements are provided. The triggerable elements allow delivery of the encapsulated anesthetic drugs when an appropriate triggering stimuli are applied. Exemplary triggering agents or stimuli include near-infrared irradiation, UV- and visible light, ultrasound and magnetic field. In one embodiment, ultrasound is used to trigger a burst of microbubbles to enhance penetration of local anesthetic.

Abstract: A polypeptide modified complex in the pharmaceutical field that can specifically adsorb apolipoproteins in plasma and can mediate a drug across the blood-brain barrier, a target delivery system, and use thereof in preparation of a formulation for diagnosing and treating brain tumors and other brain diseases. The polypeptide fragment (SP) of the amyloid ? (relating to one type) is modified shown that the modified delivery system increases uptake the of the amyloid ? by vascular endothelial cells after the modified delivery system forms a protein crown with plasma proteins. The modified liposome delivery system delivers a drug to the lesion site more effectively, significantly improving the therapeutic effect of the drug. After the SP adsorbs plasma proteins, a drug may be mediated across the blood-brain barrier and/or targeted to tumor neovascular and tumor cells, and the modified drug and delivery system thereof obtain a better therapeutic effect when treating brain tumors and other diseases in the brain.

Abstract: Compositions and methods for prolonging the local anesthetic effect of site 1 sodium channel blockers and local anesthetics with minimal or reduced toxicity have been developed for ophthalmic use. It has been established that agents such as dexmedetomidine having alpha-2-adrenergic agonist and Hyperpolarization-activated cyclic nucleotide-gated channel antagonist activity can dramatically prolong the duration of nerve blockade when administered to the surface of, a compartment of or tissue adjacent to, the eye. A preferred active agent for prolonging the local anesthetic effect of site 1 sodium channel blockers or local anesthetics is Dexmedetomidine.

Abstract: The present invention relates to a group of MDM2 and MDMX antagonists, namely, D-peptides, variants thereof, and stapled D-peptides, along with pharmaceutical compositions comprising the antagonists, and methods of treating conditions such as cancer using the antagonists.
