摘要:
A cell-targeted polymeric drug delivery system was designed based on the specific interaction between hyaluronic acid (HA) and its cell surface receptors overexpressed on cancer cell surface. The invention relates to compounds composed of a carrier molecule, wherein the carrier molecule contains at least one residue of an anti-cancer agent and at least one residue of a hyaluronic acid. The invention also relates to methods of making and using the compounds thereof.
摘要:
Novel degradable macromolecular magnetic resonance imaging contrast agents for use in various diagnostic procedures, and methods for synthesizing, using and degrading these agents, are disclosed. The macromolecule contrast agents disclosed in various aspects of this invention are degradable gadolinium compounds which show prolonged plasma retention, and enhanced permeability and retention in solid tumors, but are still capable of being rapidly cleared from the body.
摘要:
Example systems and methods enhance contrast in MRI images. To facilitate imaging of atherosclerotic plaques, arterial and venous, cardiac, and even tumor tissues and fibrosis, a fibrin-fibronectin complex or disease-related fibronectin specific MRI contrast agent (CLPD) has a specific binding affinity for fibronectin.
摘要:
Described herein are peptide targeting imaging agents. The peptides are covalently attached to the imaging agent and have a specific peptide sequence that enables the imaging agent to accumulate specifically in tumor tissues. Additionally, the imaging agents are readily excreted by the subject within a short period of time after administration to the subject. Methods for using the imaging agents are also described herein.
摘要:
Described herein are methods for using macromolecular MRI contrast agents to evaluate the effectiveness of anti-cancer treatments. The methods take advantage of MRI for evaluating more specifically and accurately one or more tumor properties of the tumor in response to a particular treatment. Ultimately, the 5 methods described herein help evaluate the effectiveness of the anti-cancer treatment over time.

摘要:
A metal treatment composition including Tin (II) Chloride and processed montmorillonite clay. The addition of Tin (II) Chloride to the composition provides Tin for forming a ceramic-metal layer on the surfaces of the friction pair. Tin (II) Chloride provides Chlorine ions for forming Chloric films for protecting juvenile surfaces which form in the friction zone. The clay is heated and pulverized to produce a powder comprising both particles having crystalline layer structure and salts and oxides. The layered crystalline structure of the clay contains slip planes that transversely shift when tangential pressure from the friction pair is applied thereby lubricating the friction pair. The salts and oxides contribute to the formation of the ceramic-metal layer.

Disclosed is a method of therapy used in combination with a diagnostic tool for enhanced photodynamic therapy using MRI, called (magnetic resonance imaging)-guided photodynamic therapy. The methods of the present invention includes administration of MRI contrast agent labeled polymer photosensitizer conjugates, detection and localization of tumor or cancer tissues with contrast-enhanced MRI and specific illumination and treatment of localized target tissues, such as tumors or cancer cells, using laser energy. The delivered laser energy activates the photosensitizer accumulated in the target tissue, resulting in treatment. Also disclosed are novel conjugate compounds, such as PLGA-Mce6-DOTA-Gd complexes, having multi-functionality in that the complex may include an MRI contrasting agent linked to a photosensitizing agent.
