Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
High spatial and temporal resolution of conditional gene expression is typically difficult to achieve in whole tissues or organisms. We synthesized two reversibly inhibited, photoactivatable ('caged') doxycycline derivatives with different membrane permeabilities for precise spatial and temporal light-controlled activation of transgenes based on the 'Tet-on' system. After incubation with caged doxycycline or caged cyanodoxycycline, we induced gene expression by local irradiation with UV light or by two-photon uncaging in diverse biological systems, including mouse organotypic brain cultures, developing mouse embryos and Xenopus laevis tadpoles. The amount of UV light needed for induction was harmless as we detected no signs of toxicity. This method allows high-resolution conditional transgene expression at different spatial scales, ranging from single cells to entire complex organisms.
