The PCL-1 probe comprises a light-emitting luciferin molecule enclosed inside a molecular cage of boronic acid. The boronic acid selectively reacts with hydrogen peroxide molecules which release the luciferin, triggering a bioluminescent reaction in the presence of firefly luciferase. In their study, Chang and his co-authors worked with transgenic mice that carried the luciferase gene. – The high sensitivity and selectivity of the PCL – 1 probe for hydrogen peroxide, favorable properties of favorable properties of the in vivo bioluminescence imaging, make an unequivocal for monitoring physiological fluctuations in hydrogen peroxide levels in real time, Chang says. This offers the possibility small-molecule disparate contributions of hydrogen peroxide to health, aging and disease.
This is a significant advance over previous hydrogen peroxide probes. ‘.. Chang and his group have shown that hydrogen peroxide can serve as highly effective signaling agent in vivo imaging achieve this they have a number of hydrogen peroxide fluorescent tags for tracking small-molecule metabolites oxygen developed in living cells, tissues and organisms new with her. PCL-1 probe, They chose the with prostate cancer, and observe variations of the hydrogen peroxide by cancer cells to the amount of by the probe by the probe generated. ‘Allows the PCL-1 probe allows us to study the chemistry in living animals such as cancer and other diseases progress,’Chang says. ‘We can see the probe in the same mouse over time, as to see therapeutics therapeutics and other treatments, its physiology , without doing biopsies or sacrifice the animal the animal.Not prepared to revealing American Wary About U.S. Healthcare Reform.
Results of survey , the biggest poll to investigate this year, the American attitude to the health care reform the legislative, have been News Maker during the National Press Club conference on the 15th July in Washington, DC released.
We are by the Obama administration and of the Kongress for their support for institution like ours and for its careful consideration from political questions, the results on the future generations, said Kaiser, one the poll author, I hope. That this scientific study are be useful she in their consultations. .
