A variety of murine transplantable tumors have been found to be immunosuppressive. In the case of viral-induced neoplasms, immunosuppression could often be related to the effects of the corresponding oncogeneic type C virus (1-3). In the case of chemically induced or spontaneous neoplasms, the concept has been raised that tumor cells, or their metabolic soluble products, were immunosuppressive ...
After the landmark, IAEA trial confirming the potential of intra-arterially used Re 188 Lipoidol for the treatment of inoperable hepatocellular carcinoma (HCC), it was surprising to note that none of the participating centers took this work forward. To a nonnuclear physician or scientist, it would seem baffling, but we in NM are well aware of the difficulties in instituting a new radionuclide t...
Objectives: To determine the cancer incidence in Gipuzkoa (Spain) from 1998 to 2002 and describe time trends since 1986. Methods: The annual incidence of cancer in Gipuzkoa from 1998 to 2002 was estimated as a rate per 100,000 inhabitants. Incidence trends for the period 1986-2002 were studied for all cancers and for the main cancer sites using Poisson regression and Joinpoint regression for pr...
There is a need for effective "broad spectrum" therapies for metastatic melanoma which would be suitable for all patients. The objectives of Phase Ia/Ib studies were to evaluate the safety, pharmacokinetics, dosimetry, and antitumor activity of (188)Re-6D2, a 188-Rhenium-labeled antibody to melanin. Stage IIIC/IV metastatic melanoma (MM) patients who failed standard therapies were enrolled in b...
We present techniques for obtaining precision astrometry using old photographic plates from assorted large-aperture reflectors in combination with recent CCD Mosaic Imager frames. At the core of this approach is a transformation of plate/CCD coordinates into a previously constructed astrometric reference frame around the open cluster NGC 188. This allows us to calibrate independently the Optica...
PURPOSE The need of prophylactic central neck dissection (PCND) in patients with papillary thyroid carcinoma (PTC) is still controversial. The major restriction of PCND is the potential complications. We undertook a retrospective study to discuss its necessity in PTC patients. METHODS A total of 188 patients with PTC who underwent total thyroidectomy and PCND were involved. In all of these, c...
INTRODUCTION New (188)Re and (99m)Tc peptide conjugates with substance- P (SP) were prepared and biologically evaluated. The radiopharmaceuticals have been labelled with the [M≡N](2+) (M=(99m)Tc, (188)Re) core using a combination of π-donor tridentate and π-acceptor monodentate ancillary ligands. METHODS The new radiopharmaceuticals have been prepared through a two-step reaction by simultaneo...
MicroRNAs (miRNAs) have recently come to be viewed as critical players that modulate a number of cellular features in various biological systems including the mature CNS by exerting regulatory control over the stability and translation of mRNAs. Despite considerable evidence for the regulatory functions of miRNAs, the identities of the miRNA species that are involved in the regulation of synapt...
This study evaluated a multifunctional micelle simultaneously loaded with doxorubicin (Dox) and labeled with radionuclide rhenium-188 ((188)Re) as a combined radiotherapy and chemotherapy treatment for hepatocellular carcinoma. We investigated the single photon emission computed tomography, biodistribution, antitumor efficacy, and pathology of (188)Re-Dox micelles in a murine orthotopic lucifer...
