Dietary administration of sodium saccharin to male Fischer rats increased the rate of DNA synthesis of the urinary bladder epithelium as measured by tritiated thymidine uptake. A multifocal mild epithelial hyperplasia was induced, which was most readily detected by scanning electron microscopy, with pleomorphic microvilli present on many of the hyperplastic cells.
It is now almost forty years since the first description of learning in the fruit fly Drosophila melanogaster. Various incarnations of the classic mutagenesis approach envisaged in the early days have provided around one hundred learning defective mutant fly strains. Recent technological advances permit temporal control of neural function in the behaving fly. These approaches have radically cha...
The long-term two-bottle choice test is commonly used as a simple screen to examine the acceptance of taste solutions by rodents. As part of an investigation of factors influencing the sensitivity of the two-bottle choice test, we determined the extent to which test duration influenced test sensitivity. C57BL6/J and 129X1/SvJ mice received four series of eight two-bottle tests, with each test l...
Investigating molecular mechanisms underlying human taste sensation requires functionally dedicated and at the same time proliferating human taste cells. Here, we isolated viable human fungiform taste papillae cells from biopsy samples, adenovirally transduced proliferation promoting genes, and obtained stably proliferating cell lines. Analysis of gene expression of 1 human taste cell line term...
Plants under attack by pathogens and pests can mount a range of inducible defences, encompassing both chemical and structural changes. Although few reports exist, it appears that plants responding to pathogen or herbivore attack, or chemical defence elicitors, may produce progeny that are better able to defend themselves against attack, compared with progeny from unthreatened or untreated plant...
The Otsuka Long-Evans Tokushima Fatty (OLETF) rat, an outbred strain of Long- Evans Tokushima Otsuka rat (LETO) that lacks CCK-1 receptor expression, is hyperphagic and develops obesity and type-2 diabetes. The present study sought to assess how OLETF rats alter intake, preference, and conditioned preference of palatable solutions after acute food deprivation. Our results show that after 24 h c...
Incorporation of sulfur into 2.4 T CoFe alloys during galvanostatic deposition has been studied. The results indicate that the main source of sulfur in magnetic deposit is saccharin used as an additive in the plating solution. The atomic percent of sulfur in deposit and the sulfur incorporation rate show strong dependence on saccharin concentration in the plating solution. This dependence has p...
