The present invention relates to implantable medical devices, such as stents, that comprise a composition for controlled delivery of flavonoids or a derivative thereof. The flavonoids are aimed at preventing or reducing secondary complications which can occur following implantation of the device such as e.g. occlusive and catastrophic vascular phenomena. The invention further relates to the inclusion of additional therapeutic agents in the system that may have antiproliferative, antimitotic, antimicrobial, anticoagulant, fibrinolytic, anti-inflammatory, immunosurpressive, and anti-angiogenic activities. The composition comprising the flavanoids and optional further therapeutic agents may be used in methods for treating or preventing narrowing or obstruction of the body passageway. In particular the devices and compositions of the invention are useful in methods for treating or preventing restenosis, e.g. subsequent to angioplasty and / or for preventing or reducing acute, subacute and chronic secondary complications associated with angioplasty, such as e.g. thrombus.

The invention provides generally a method of monitoring, diagnosing, prognosing and treating glioma. Specifically, the invention provides for three (3) prognostic subclasses of glioma, which are differentially associated with activation of the akt and notch signaling pathways. Tumor displaying neural or proneural PN lineage markers (including notch pathway elements) show longer median patient survival, while the two remaining tumor markers Prolif and Mes are associated with shortened survival. Tumors classified in this manner may also be treated with the appropriate PN- Prolif- or Mes- therapeutic corresponding to the subclassification in combination with anti-mitotic agents, anti-angiogenic agents, Akt antagonists, and neural differentiation agents. Alternatively, the invention also provides for method of prognosing and diagnosing glioma with a two- gene model based on the expression levels of PTEN and DLL3.

Methods and compositions for the development of effective cancer therapies using mitotic inhibitors which have limited general toxicity to normal, non-cancerous cells and tissues are provided. The methods and compositions utilize cytotoxic compounds comprised of a cell-binding agent (e.g., antibodies) conjugated to an anti-mitotic compound (e.g., maytansinoids). The invention further provides antibodies which are substantially incapable of inducing antibody-dependent cell-mediated cytotoxicity (ADCC) and / or complement dependent cytotoxicity (CDC), thereby ensuring that the therapeutic effect is mediated primarily by the anti-mitotic component of the cytotoxic compound, rather than by indirect cell killing via ADCC and / or CDC. The antibodies of the invention further are capable of differentiating between polypeptide antigens which are more highly expressed on proliferating cancer cells as compared to proliferating non-cancer cells.

The present invention discloses a method for high throughput screening (HTS) for identifying an analyte with a measurable effect on cells. The aforementioned method comprises steps of: (a) providing an array comprising a plurality of cell samples; (b) providing at least one analyte to be tested; (c) contacting said cell samples with said analyte; and (d) detecting a signal indicative of said measurable effect on cells wherein alteration of said signal over time measured on said cell sample relative to a control sample is indicative of said measurable effect of said analyte on said cell sample.The current invention further discloses means and methods for identifying an analyte selected from the group consisting of: cannabis extract or a fraction thereof cannabinoid- type constitute non cannabinoid-type constitute and any combination thereof. The analyte is indicative of cytotoxic or anti proliferative or anti mitotic or cell growth inhibitory activity in vitro.
