DESCRIPTION (provided by applicant): This proposal outlines a body of research to evaluate the cytotoxicity and therapeutic efficacy of radiolabeled alpha-melanocyte stimulating hormone (a-MSH) peptide analogs that target a-particle emitting radioisotopes to the nuclei of melanoma cells. The selective targeting of alpha-particle emitting radioisotopes for cancer therapy is emerging as an exciting ...

DESCRIPTION (provided by applicant): NIH sponsored cancer researchers have been obtaining promising results using molecules radiolabeled with lead-212 in treatment for metastatic melanoma and disseminated colon and pancreatic cancers. Another isotope, radium-223 is being used in clinical trials in treatment of skeletal metastases. There is no effective therapy for these diseases. Together 199,280 ...

DESCRIPTION (provided by applicant): Prostate cancer is the most prevalent cancer among men; and the second leading cause of cancer death among men in the US. There are currently no approved therapies for hormone-refractory prostate cancer. Epidemiological studies have demonstrated a strong relationship between incidence of and mortality from various cancers including prostate cancer, exposure to ...

DESCRIPTION (provided by applicant): Monitoring the effects of pharmaceutical or radiation intervention in cancer patients is an important tool in the management of disease. Current methods for monitoring tumor response to therapy using imaging include CT and PET scanning. Emerging methods include functional and molecular imaging. In addition to the use of imaging to visually assess tumor growth, ...

DESCRIPTION (provided by applicant): Human embryonic stem cells (HuES) have the potential to generate an unlimited source of beta/islet cells for transplantation, however the biologic factors required for this process have been difficult to ascertain partly due to the lack of stage specific in vitro cell assays. Recently, we have developed a murine in vitro pancreatic stem/progenitor colony assay ...

DESCRIPTION (provided by applicant): Mycobacterium tuberculosis and other Mycobacterium species are major pathogens around the world. They are part of a larger group of so-called fastidious pathogens that are difficult to study because, for a wide range of reasons, they are difficult to culture. Phenotype MicroArrayTM (PM) technology is a tool that can aid in understanding the physiological and me ...

DESCRIPTION (provided by applicant): Our long term goal is to develop a universal cell-based therapy containing human myeloid progenitor cells to attenuate radiation-induced gastrointestinal or hematopoietic injury. Radiation (XRT) remains an important therapeutic modality in the treatment of malignancies. Injury to the gastrointestinal tract (GI) and hematopoietic system are serious sequelae of r ...

DESCRIPTION (provided by applicant): Cerebral autoregulation that maintains perfusion in response to fluctuations of systemic blood pressure (BP) is lost post-stroke and traumatic brain injury (TBI). Noninvasive bedside methods are urgently needed to identify people with impaired autoregulation who may be at increased risk for stroke and adverse outcomes. The phase I goals are: 1) To develop and o ...

DESCRIPTION (provided by applicant): The development of a new technology for reagentless multiplexed determination of protein concentrations in clinical and biological samples is proposed. The proposed approach employs nanotubes with molecular sized openings embedded within a mechanical and chemically robust polymeric membrane. We propose that a microarray may be constructed using these membranes ...
