Location models on networks typically have a set of clients who have demand for services or commodities, and facilities to serve the clients. Location problems have many applications in the area of operations research. Various problems arise while imposing constraints on the clients and/or the facilities. One of the constraints could be to use a minimum(More)
Betulinic acid (BA), a plant derived triterpenoid, isolated from various sources shows cytotoxicity in cell lines of melanoma, neuroectodermal and malignant brain tumors. Chronic myelogenous leukemia (CML) is characterized by Philadelphia chromosome (Bcr-Abl), a molecular abnormality leading to the intrinsic tyrosine kinase activity that provides growth and(More)
Betulinic acid (BA) is known to induce apoptosis in melanoma neuroectodermal and malignant brain cancer cell lines. Present report describes the role of antioxidants on the BA-induced toxicity to human cell line SK-N-MC. Hydrophilic antioxidants viz., L-ascorbic acid (VitC) and N-acetyl-L-cysteine (l-NAC) had no protective effect on BA-induced apoptosis at(More)
The induction and rejoining of gamma-ray-induced DNA single-strand breaks (SSBs) were measured in the spermatogenic cells of mice using the alkaline elution technique. The animals were injected with [3H]thymidine and sacrificed on subsequent days to examine selectively cohorts of radiolabeled cells in the successive stages of maturation. A significantly(More)
Recent findings that retinoic acid (RA) induces terminal granulocytic differentiation of the human promyelocytic leukemia cell line HL-60 in vitro and blast cell maturation in patients suffering from acute non-lymphocytic leukemia (ANLL) prompted an investigation on the ability of this agent to induce terminal maturation in blast cells from ANLL patients in(More)
Phorbol ester, 12-0-Tetradecanoyl-13-Phorbol-Acetate (TPA), induces a terminal macrophage-like differentiation of cells from human acute myelogenous leukemia cell lines. We report here that blastoid cells obtained from acute nonlymphocytic leukemia (M1-M2) undergo differentiation-related changes characteristic of macrophage lineage after exposure to TPA.(More)
