The cell-mediated immune response of C57BL/6 mice to murine sarcoma virus (MSV) was examined by the [125I]-iododeoxyuridine release cytotoxicity assay using MSV-induced sarcoma tissue culture cell lines as target cells. Cellular cytotoxicity was detected as early as 3 days after virus inoculation.
Humans are exposed to cobalt (Co) and chromium (Cr) from industry and surgical devices, most notably orthopedic joint replacements. This review compares the potential health effects of exposure to Co and Cr contaminants from these two different sources, both in the locally exposed tissues and at
A newly induced syngeneic transplantable sarcoma, MCA 105, was used for studies of the biologic characteristics of fresh noncultured and secondarily in vitro sensitized (IVS) cells with antitumor reactivity. Fresh spleen cells harvested from mice immunized to the MCA 105 tumor by a mixture of viable
Autolymphocyte therapy (ALT) is tumor-specific, adoptive cellular therapy of neoplastic disease using nonspecific ex vivo activation of autologous peripheral blood lymphocytes (PBL), which are composed primarily of memory T-cells (ALT-cells) and are active in patients with metastatic renal cell
Malignant tumors around fracture fixation implants have been reported sporadically for many years. Recently, however, reports of sarcomatous degeneration around a standard cemented hip arthroplasty and around cobalt-chromium-bearing hip arthroplasties raise new questions of the malignant potential
Kaposi sarcoma (KS) is the most common AIDS-associated malignancy and is characterized by angiogenesis and the presence of spindle cells. Kaposi sarcoma-associated herpesvirus (KSHV) is consistently associated with all clinical forms of KS, and in vitro infection of dermal microvascular endothelial
Increase in neoplasia in offspring after preconception exposure of parents presents puzzling features such as high frequency of effects and lack of Mendelian inheritance. The present study examined the hypothesis that preconception carcinogenesis involves an increase in the rate of occurrence of
The purpose of this study was to determine the potential use of lymphokine-activated killer (LAK) cells against Kaposi's sarcoma (KS) cells. We used chromium release cold-target inhibition assay for understanding the expression of heterogeneous LAK-cell antigens (Ags) on KS cells, endothelial cells
BACKGROUND
Ewing sarcoma patients have a poor prognosis despite multimodal therapy. Integration of combination immunotherapeutic strategies into first-/second-line regimens represents promising treatment options, particularly for patients with intrinsic or acquired resistance to conventional
Advances with implantation of synthetic biomaterials in the setting of orthopedic surgery have clearly resulted in improvements in patient outcomes. However, all implants have been shown to have associated risks. For example, ionic and particulate debris from implants have been shown to engage in
BACKGROUND
We hypothesized that pressure stimulates colon cancer cell adhesion to surgical wounds.
METHODS
We quantitated adhesion of murine 26/51 transplantable colon cancer cells by cell counting or chromium 51-labeling. Tumor cells were added to murine surgical wounds after 30 minutes
A series of 43 dogs with spontaneous melanomas, sarcomas, or mammary carcinomas were tested for peripheral blood lymphocytotoxicity against a range of allogeneic tumor cells in vitro on one or more occasions during therapy. All tumor-bearer groups contained a proportion of dogs showing a significant
Utilizing controlled cryopreservation techniques, we were able to standardize the 51Cr release cytotoxicity assay and thereby ensured reliable comparisons between results obtained on different days. Optimal conditions for freezing of both effector and target cells were quite similar. Dimethyl
