conclusions chronic meningitis in immunocompromised hosts can be due to more than one pathologic etiology and we should do all diagnostic evaluation to rule out all possible differential diagnosis. introduction cryptococcal meningitis is a rare disorder that is caused by cryptococcus neoformans in immunocompromised host. case presentation the case was a 64-year-old man with a history of stem ce...

BACKGROUND Taurolidine (TRD) represents an anti-infective substance with anti-neoplastic activity in many malignant cell lines. So far, the knowledge about the cell death inducing mechanisms and pathways activated by TRD is limited. The aim of this study was therefore, to perform a comparative analysis of cell death induction by TRD simultaneously in different malignant cell lines. MATERIALS ...

The mechanism involved in leukemogenesis and neoplastic cell growth of adult T-cell leukemia (ATL) still remains unclear. We examined the tumorigenicity of human T-cell leukemia virus type I (HTLV-I)-infected cell lines in an in vivo cell proliferation model using severe combined immunodeficient (SCID) mice. Eleven HTLV-I-infected cell lines were injected into SCID mice and we found that 4 of t...

The reduced gap junctional intercellular communication (GJIC) and gap junction protein (connexin) expression that have been noted in many neoplastic cell types may contribute to the neoplastic phenotype. We assessed GJIC (by fluorescent dye micro-injection) and connexin expression (by Northern blotting, Western blotting and immunohistochemistry) in five mouse and 17 human lung carcinoma cell li...

BACKGROUND Molecular-level differentiation of neoplastic cells is essential for accurate and early diagnosis, but effective molecular probes for molecular analysis and profiling of neoplastic cells are not yet available. We recently developed a cell-based SELEX (systematic evolution of ligands by exponential enrichment) strategy to generate aptamers (designer DNA/RNA probes) as molecular probes...

the aim of this work was to see whether tamarin immunisation with recombinant vaccinia virus expressing epstein barr virus latent proteins could prime t cells which were, on activation, able to inhibit the outgrowth of epstein barr virus transformed cells in vitro. the vaccination appeared to be successful as all vaccinated tamarins developed vaccinia lesions. however, the vaccination protocol ...

Adherent fibroblast-like cells from paired lines, one non-neoplastic and the other "spontaneously" transformed neoplastic, were compared in simultaneous in vivo and in vitro assays. The in vivo assay was the i.m. implantation of 10(6) or 10(7) cells in irradiated syngeneic animals, and the two in vitro assays were the evaluation of colony morphology on plastic and the enumeration of colony grow...

background: treatment of cancer patients using conventional chemotherapy causes serious side effects and, at best, merely extends the patient’s lifespan by a few years. the potential of alternative therapies may therefore be of great benefit in cancer control. the effect of trigonella foenum graecum seed extract has been previously reported on some neoplastic cells. here, its effect is evaluate...
