4D OCT Helps to Solve Mystery of Early Embryonic Heartbeat
HOBOKEN, N.J., Aug. 12, 2020 — Scientists from Stevens Institute of Technology and Baylor College of Medicine used 4D optical coherence tomography (OCT) to study the pumping mechanism underlying the developing mammalian heart. 4D OCT allowed them to investigate the functional relation between blood flow and heart wall dynamics within different regions of the embryonic heart at a level of detail not currently accessible by other methods. 4D OCT could potentially enable scientists to assess cardiac pumping over embryonic
Fiber Microendoscope Could Reduce Unnecessary Biopsies
HOUSTON, June 3, 2015 — A low-cost, portable, battery-powered microendoscope developed at Rice University could reduce the need for costly biopsies for many patients undergoing screening for esophageal cancer. That's the conclusion of researcher behind a clinical study...
Nanobubbles Destroy Some Cells, Treat Others
HOUSTON, Dec. 4, 2012 — A single laser blast can activate plasmonic nanobubbles that selectively kill diseased cells while at the same time treating others, and leaving neighboring healthy cells untouched.
Dual-Purpose Neural Probe Enables New Capabilities
HOUSTON, June 13, 2012 — A new device that combines light delivery with a tetrode into a single neural probe may offer new ways of studying small clusters of brain cells.
Nanoparticle-Laser Method Targets Chemo Drugs
HOUSTON, April 10, 2012 — A potential treatment method for drug-resistant cancer uses gold nanoparticles to convert laser energy into “plasmonic nanobubbles,” which allow chemotherapy drugs to enter single cells. Delivering chemotherapy with nanobubbles is 30 times more...
Laser Surgery Promising as Epilepsy Cure
HOUSTON, July 26, 2011 — To most parents, a child’s laughter is music to their ears, but when 8-year-old Keagan Dysart laughed, it meant he was having a gelastic seizure — a rare convulsion that caused him to laugh uncontrollably two to three times an hour. But...
Imaging a Heart’s First Beat
HOUSTON, April 16, 2010 — Through high-resolution, non-invasive imaging, scientists are documenting the formation of the mammalian heart and are capturing video of the embryonic heart before it begins beating. Kirill Larin, assistant professor of biomedical engineering in...
Neurons Imaged Fast in 3-D
HOUSTON, April 28, 2008 -- A technique that combines a laser beam with a multiphoton microscope allows scientists to quickly observe the function of neurons, or nerve cells, in three dimensions, providing a much better view of their fast activity. Scientists at Baylor...
Virus Imaged in Great Detail
WEST LAFAYETTE, Ind., March 6, 2008 -- Single-particle electron cryomicroscopy, also known as cryo-EM, has been used to capture a 3-D image of a virus with near atomic-level resolution, the highest level of detail achieved for a living organism of that size. A team led by Wen Jiang,...
Nanoparticles Sneak Drugs into Cancer Cells
HOUSTON, Jan. 18, 2007 -- A new use for Buckyball nanoparticles has been discovered -- as "passkeys" that allow drugs to enter cancer cells. All living cells defend themselves by walling off the outside world. Cell walls, or membranes, form a protective cocoon around the...
Four Lasers Used for Color-Blind DNA Sequencing
May 1, 2005 — Increasing the speed and accuracy of DNA sequencing and decreasing its cost are necessary for it to become a routine part of individualized medicine. Traditionally, identifying the order of bases in a sequence has required the labeling of pieces of...
