NTP Announces Bioassay Results
-Peripheral-blood basophils were counted, in thick smears, in samples from patients with primary bronchial carcinoma, from patients in the same wards and from normal individuals. The median counts for patients with other chest conditions (15-5/4d) and bronchial-carcinoma patients free of tumour months to years after resection (16/1l) did not differ from those for normal individuals (19/1,u), bu...
متن کاملNew NTP bioassay results.
Background: Trichophyton rubrum is the most common dermatophyte species and the most frequent cause of fungal skin infections in humans worldwide. It's a major concern because feet and nail infections caused by this organism is extremely difficult to cure. A large set of expression data including expressed sequence tags (ESTs) and transcriptional profiles of this important fungal pathogen are n...
متن کاملPhenolphthalein highlights NTP bioassay review.
Background: The aim of the study was to determine the maximal tolerated dose (MTD) of gemcitabine every two weeks concurrent to radiotherapy, administered during an aggressive program of sequential and simultaneous radiochemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC) and to evaluate the efficacy of this regime in a phase II study. Methods: 33 patients with his...
متن کاملUse of a multistrain assay could improve the NTP carcinogenesis bioassay.
There are often large strain differences in the response of laboratory animals to toxic chemicals and carcinogens, with some strains being totally resistant to dose levels that cause acute toxicity and/or cancer in other strains. The current National Toxicology Program carcinogenesis bioassay (NTP-CB) uses only a single isogenic strain of mice and rats and may therefore miss some carcinogens. N...

The use of heat treatment for the removal of non-specific effects in the direct radioimmunoassay of human circulatory CEA has been widely adopted have shown the existence of heat-labile determinants on CEA which may be destroyed by this assay technique. Heat-labile antigens appeared to be shared between CEA isolated from tumour and normal colon whilst the heat-stable antigens appeared to be mor...
