Reverse mutation assay: No data gap, no adverse effect In vitro mammalian cell assay: No data gap, possible adverse effect In vivo cytogenetics assay: No data gap, no adverse effect Neurotoxicity: No data gap, possible adverse effect † † Hen neurotoxicity study did not indicate distal delayed neuropathies, but acetylcholinesterase inhibition was flagged as " possible adverse effect " in several...

The seeds of Lupinus termis are used in the Middle East and Africa as food and in folklore medicine. In traditional medicine, the seeds are reputed to be effective for diabetes. Topically, the powdered seeds are used to treat acne, and in clinical studies performed outside the U.S.A., the ethanolic extract demonstrated efficacy in the treatment of chronic hand and foot eczema. In order to evalu...

The aim of the present study was to establish screening biomarkers of exposure to antineoplastic drugs administered to 11 patients undergoing cancer chemotherapy. Among the anticancer drugs administered were cyclophosphamide (all), Adriamycin (5 of 11), methotrexate (3 of 11), 5-fluorouracil (4 of 11), vincristine (3 of 11), megestrol acetate (1 of 11), and procarbazine (1 of 11). The noninvasi...

Mutagens can be carcinogens, and traditionally, they have been identified in vitro using the Salmonella 'Ames' reverse mutation assay. However, prokaryotic DNA packaging, replication and repair systems are mechanistically very different to those in the humans we inevitably seek to protect. Therefore, for many years, mammalian cell line genotoxicity assays that can detect eukaryotic mutagens as ...

background and objectives: numerous procedures in biology and medicine require the counting of cells. direct enumer- ation of colony forming units (cfus) is time-consuming and dreary accurate cell counting on plates with high numbers of cfus is error prone. in this study we report a new indirect cell counting method that was developed based on the use of redsafe fluorometric assay. the usefulne...

INTRODUCTION Many studies on the biological effects of electric and magnetic fields have been conducted since Wertheimer and Leeper reported an association between wiring configuration and childhood cancer among residents in Denver, Colorado. The genetic effects, especially mutagenicity and carcinogenicity, of electromagnetic fields have also been studied experimentally with positive and negati...

PURPOSE Stomatin-like protein 2 (SLP-2) is a novel and unusual stomatin homologue of unknown functions. It has been implicated in interaction with erythrocyte cytoskeleton and presumably other integral membrane proteins, but not directly with the membrane bilayer. We show here the involvement of SLP-2 in human esophageal squamous cell carcinoma (ESCC), lung cancer, laryngeal cancer, and endomet...

Abstract : Avian influenza virus (AIV) infection is a major cause of influenza mortality in birds and can cause human mortality and morbidity. Although the risk of infection with avian influenza virus (AIV) is generally low for most people, the pathogenic virus can cross the species barrier and acquires the ability to infect and be transmitted among the human population; therefore the ra...
