27 Feb 1991TL;DR: In this article, a junction reactor aligns a pair of capillaries (513, 514) substantially collinearly, end-to-end that allows a small gap (512) to be produced between these two ends.
Abstract: A junction reactor (50) that aligns a pair of capillaries (513, 514) substantially collinearly, end-to-end that allows a small gap (512) to be produced between these two ends. An applied voltage difference between the other ends of these two capillaries producces in the gap (512) electric fields lines that extend across the gap (512). Empirical evidence shows that the gap (512) introduces only a small reduction in resolution of an electrophoretic or electrochromatographic separation. The gap (512) enables sample liquid to be coupled between capillaries (513, 514) of different internal diameters and enables on-capillary reactions such as attaching a fluorescent tag to a sample components.

TL;DR: The case for a link between sunlight and this increasingly common cancer is strengthened, with a correlation between hprt(-) mutant frequency and the sunlight record for the 3 weeks prior to taking the blood sample found.
Abstract: Between 1983 and 1995 we have monitored human populations for evidence of exposure to environmental mutagens, taking blood samples to measure hprt - mutant frequency in T cells and more recently bcl-2 t(14:18) translocation frequency in B cells. We have now analysed data from 785 assays on 448 blood samples from 308 normal subjects and find that there is a highly significant statistical correlation between hprt - mutant frequency and the sunlight record for the 3 weeks prior to taking the blood sample. We discuss the weaknesses in retrospective studies of this nature and the possibility of spurious epidemiological correlations that may result. More controlled experiments can be envisaged that would give a firmer basis to the statistical associations observed, hprt - mutations in T cells show little evidence of a UV fingerprint, so that the correlation may be due to immunomodulation rather than mutation. We also find a correlation between the sunlight record and bcl-2 translocation. This translocation is found at a low frequency in the B cells of many normal subjects and is the commonest translocation observed in non-Hodgkin's lymphoma. Our results strengthen the case for a link between sunlight and this increasingly common cancer.

TL;DR: The combined use of the 2′-tetrahydropyran-4-yl(Thp group and 5′-9-phenylxanthen-9yl(Pix) group gave satisfactory results in the solid phasesynthesis of medium sized RNA fragments.

25 Jun 2007TL;DR: In this article, an expandable valve is configured to exert a force on a membrane layer so as to substantially block a portion of the channel to retain the sample in a desired location and prevent flow past the valve mechanism between the channel and a chamber.
Abstract: A device and methods for sample distribution through a channel in which an expandable valve provides a mechanism to regulate flow through the channel. The valve may be configured to exert a force on a membrane layer so as to substantially block a portion of the channel to retain the sample in a desired location and prevent flow past the valve mechanism between the channel and a chamber.
