  • Publication number: 20240115552
    Abstract: Mebendazole is an antiparasitic drug with over 40 years of safe use. Recently mebendazole was repurposed for glioblastoma therapy. Three polymorphs of mebendazole exist, but the relative polymorph content for existing drugs varies, and the therapeutic anti-cancer relevance of the different polymorphs was unknown. As an oral drug mebendazole polymorph C is a superior form, and it reaches the brain and brain tumors in effective concentrations. Efficacy is further improved by combining mebendazole with a P-glycoprotein inhibitor. Mebendazole may also be used for therapy of other cancers, as well as a chemo-preventative agent.

  • Publication number: 20190231802
    Abstract: A chemotherapeutic-releasing implantable stick is described herein. The chemotherapeutic-releasing implantable stick includes an implantable stick having a length and thickness to fit within a needle track from a needle biopsy, the implantable stick providing a biocompatible and biodegradable substrate for the release of a chemotherapeutic agent when implanted. The chemotherapeutic-releasing implantable stick further includes a chemotherapeutic agent absorbed into the implantable stick.

  • Patent number: 8394580
    Abstract: This invention relates, e.g., to a method for detecting the presence of lymph node metastases in a subject having papillary thyroid carcinoma (PTC), comprising measuring in a sample from the subject the amount of expression (e.g., the amount of protein, or the amount of mRNA encoding the protein) of one or more of the following proteins: (a) LIMD2, and/or (b) PTPRC, and/or (c) LTB, and/or (d) CD48, and/or (e) ABCC3, wherein a significant amount of over-expression of one or more of protein(s) (a)-(e), compared to the baseline value, indicates that lymph node metastases are likely to be present in the subject.

  • Publication number: 20060035244
    Abstract: Follicular thyroid adenoma (FTA) is distinguished from follicular thyroid carcinoma (FTC) by comparing amount of an expression product of at least one gene selected from the group consisting of DDIT3, ARG2, ITM1, Clorf24, TARSH, and ACO1 in a test follicular thyroid specimen to a normal control thyroid specimen. The test follicular thyroid specimen is identified as FTA if the amount of expression product of TARSH is equal to or greater in the test follicular thyroid specimen than in the normal control thyroid specimen. The test follicular thyroid specimen is identified as FTC if the amount of expression product of DDIT3, ARG2, ITM1, Clorf24, or ACO1 is greater in the test follicular thyroid specimen than in the normal control thyroid specimen.
