Quiescent BALB/c-3T3 cells exposed briefly to platelet-derived growth factor (PDGF) become "competent" to replicate their DNA even if PDGF is removed from cell culture medium prior to the onset of DNA synthesis. We have suggested that persistence of the PDGF-induced competent state reflects a rapidly induced and relatively stable biochemical change within the target cells. Others suggest that t...

A phototrophic enrichment culture, using acetate as carbon source, reductively dechlorinated 2,3,5,6-tetrachlorobiphenyl. ortho chlorines were removed preferentially over meta chlorines. Triand dichlorobiphenyls were the major, products. During 14 months incubation, chlorine was removed from 58% of the target molecules; 19% of the total chlorines were removed. Dechlorination did not occur in a ...

this study aimed at providing learners with an opportunity not only to bring together their core and disciplinary knowledge to acquire major skills of learning english as a foreign language (efl), and the intellectual challenge of these issues at the interface of media, language and religion, but also help the materials generators to produce suitable types of content to be delivered through the...

LLocalization aims to adapt a product so that it feels “natural” to end-users in a target locale. This suggests that without localization, the product will feel foreign due to differences in knowledge — epistemic differences — between the source and target locales. These differences arise because culture and language frame how we understand our experiences and how we think of ourselves as a col...

This paper proposes a microbe culture technology in an open environment using hydrogel microtubes. Oil production microbes, such as Aurantiochytrium, have been discovered and are currently studied to produce fuels instead of fossil fuels. Scale-up of the culture systems of such microbes is critical for practical applications. The microbe culture in a nutrition-rich open environment, such as lak...

Advantages of PCR assays over more conventional culture-based diagnostics include significantly higher sensitivities and shorter turnaround times. They are particularly useful when patient treatment has already been initiated or for specimens that may contain microorganisms that are slow-growing, difficult to culture, or for which culture methods do not exist. However, due to genome variability...
