1. The total lipid was extracted from BP8/C3H ascites-sarcoma cells with acetone, light petroleum, pyridine and chloroform-methanol successively. Each extract was treated with mild alkali. The alkali-stable lipids from the pyridine and chloroform-methanol extracts, which included the glycolipids,
Bacillus firmus is a Gram-positive, aerobic, sporulating, nonpathogenic air contaminant which, according to earlier findings, is a strong polyclonal activator of B lymphocytes. The crude lipids of this microbe induced significant resistance of mice against listerial infection. The administration of
The effect of rotating magnetic field (RMF) was studied on the growth of Deals' guinea pig sarcoma (DGPS) transplanted subcutaneously into the inguen of guinea pigs. The 0.2 ml of transplanted suspension contained 1.5-2.0 x 10(6) of vital DGPS cells. Over a period of 24 days the animals were daily
Focus formation by Rous sarcoma virus (RSV) was significantly enhanced when virus was incubated with the saline fraction of chloroform extracted chicken egg yolk, prior to infecting chicken embryo cells. The enhancement was restricted to members of RSV subgroups B, C and D and was proportional to
We have used photoaffinity labeling to investigate the distribution and function of daunomycin binding sites in Sarcoma 180 cells. When native daunomycin is irradiated at 366 or 488 nm in the presence of cells, the drug is irreversibly incorporated into cellular molecules. The cellular acceptor for
Purpose. MDM2 is an oncogene whose protein product may promote tumorigenesis by blocking wild-type p53 tumor suppressor mediated G (0)/G(1) cell cycle arrest, thereby inhibiting repair of damaged DNA prior to cell division. While MDM2 DNA amplification is frequently observed in human sarcoma, the
BACKGROUND
Cordyceps taii, an entomogenous fungus native to south China, is a folk medicine with varieties of pharmacological activities including anticancer effect. To validate the ethnopharmacological claim against cancer, the antitumor and antimetastatic activities of chloroform extract of C.
OBJECTIVE
In this phase II and pharmacokinetic study, chronic, low-dose, oral etoposide was evaluated for its efficacy in patients with AIDS-related Kaposi's sarcoma who were not previously exposed to cytotoxic therapy.
METHODS
Of 28 patients accrued for the study, 25 were assessable for toxicity
Alterations to p53 seem to be of prognostic significance in soft tissue sarcomas, but their significance for synovial sarcomas has not been studied. We analysed 34 synovial sarcomas in 19 patients for p53 alterations (p53 gene mutations + p53 immunopositivity) and examined this factor for its
OBJECTIVE
In this retrospective study, we defined the clinicopathologic characteristics of oral Kaposi's sarcoma (KS) and determined the presence of human herpesvirus 8 in the oral lesions in a group of South African patients. These results were compared with similar data from patients in developed
BACKGROUND
Ruta angustifolia Pers. is a perennial herb that is cultivated worldwide, including Southeast Asia, for the treatment of various diseases as traditional medicine.
OBJECTIVE
The purpose of the study was to identify an active principle of R. angustifolia and to investigate its effect on the
OBJECTIVE
Defining the mechanism of infection with human herpesvirus-8 (HHV-8) or Kaposi's sarcoma associated herpesvirus (KSHV) is an important clinical issue. HHV-8 has been linked to Kaposi's sarcoma (KS) development in HIV-1-infected individuals, and KS develops in 40% of those infected with
The Orchidaceae family is appreciated worldwide for the beauty of its flowers, and hundreds of species of this family occur in Brazil. Yet little is known about the potential of orchids for therapeutic application. We have investigated bioactive compounds produced by the South Brazilian orchid
Biological properties of two strains of simian virus 40 (SV40) from brains of two patients with progressive multifocal leukoencephalopathy (PML) have been compared to those of a standard laboratory strain of SV40. Infectivity of both SV40-PML viruses was resistant to treatment with chloroform, low
