Professor publishes on first-ever imaging of cells growing on spherical surfaces

Applications include new cancer detection strategies

2012-09-22
(Press-News.org) MELBOURNE, FLA.—Shengyuan Yang, Florida Institute of Technology assistant professor of mechanical and aerospace engineering, with graduate student Sang Joo Lee, has published a paper on the first-ever imaging of cells growing on spherical surfaces. The paper is published in the online journal, Review of Scientific Instruments, and will appear later in September in the print version.

The potential biomedical applications of the researchers' technique include new strategies and devices for the early detection and isolation of cancer cells, facilitating new methods of treating cancer tissues. "We also foresee new strategies and techniques to control the differentiation of stem cells and the morphologies and structures of the resulting cells and tissues," said Yang.

The effects of substrate stiffness on cell behaviors have been extensively studied; however, the effects of substrate curvature are not well-documented. The curvature of the surface on which cells adhere can have profound effects on cell behaviors, according to Yang.

"To reveal these cell mechano-biological responses to substrate curvatures, we have introduced a novel, simple, and flexible class of substrates, polyacrylamide gels embedded with micro glass balls ranging in diameter from 5 mm to 2 mm, to culture cells. To the best of our knowledge, this is the first experimental attempt to study cell responses to spherically-shaped substrates. Our cell culture experiments imply that this class of substrates, micro glass ball embedded gels, can be useful tools to study cell mechanobiological responses to substrate curvatures, related cell and tissue engineering researches, and biomedical applications, such as cancer detection and treatment, and the control of stem cell differentiations, for example," said Yang.

This work was supported with funding from the National Science Foundation (NSF) CAREER Program. The reviewer of this paper at Review of Scientific Instruments commented, according to Yang: "This is a clever idea. . . This work has great potentials with high impact."

Einstein hosts its first stem cell institute symposium

2012-09-22
September 21, 2012 – (BRONX, NY) – The promise of stem cells seems limitless. If they can be coaxed into rebuilding organs, repairing damaged spinal cords and restoring ravaged immune systems, these malleable cells would revolutionize medical treatment. But stem cell research is still in its infancy, as scientists seek to better understand the role of these cells in normal human development and disease. On Friday, September 14, the Ruth L. and David S. Gottesman Institute for Stem Cell and Regenerative Medicine Research at Albert Einstein College of Medicine of Yeshiva ...

NASA satellite sees Tropical Storm Jelawat form in northwestern Pacific

NASA satellite sees Tropical Storm Jelawat form in northwestern Pacific
2012-09-22
As another tropical storm was forming in the northwestern Pacific Ocean, NASA's Terra satellite was providing forecasters at the Joint Typhoon Warning Center with visible and other data on the storm. NASA's Terra satellite passed over Tropical Depression 18W before it strengthened into Tropical Storm Jelawat late in the day on Sept. 20, in the Philippine Sea (part of the western North Pacific Ocean basin). On Sept. 20 at 01:50 UTC, as the depression was strengthening into a tropical storm, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's ...

Undertreatment of common heart condition persists despite rapid adoption of novel therapies

2012-09-22
A novel blood thinner recently approved by the FDA, dabigatran (Pradaxa), has been rapidly adopted into clinical practice, yet thus far has had little impact on improving treatment rates for atrial fibrillation. This is according to a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health that examined national trends in oral anticoagulant use. They found that despite rapid adoption of dabigatran for the treatment of atrial fibrillation, a large proportion of patients–two in five–did not receive oral anticoagulant therapy. In addition, although ...

Simple ovarian cancer symptom survey that checks for 6 warning signs may improve early detection

2012-09-22
SEATTLE – A simple three-question paper-and-pencil survey, given to women in the doctor's office in less than two minutes, can effectively identify those who are experiencing symptoms that may indicate ovarian cancer, according to a study by researchers at Fred Hutchinson Cancer Research Center. The study represents the first evaluation of an ovarian cancer symptom-screening tool in a primary care setting among normal-risk women as part of their routine medical-history assessment. The results are published online in the Open Journal of Obstetrics and Gynecology. Early ...

Naked mole-rats may hold clues to pain relief

2012-09-22
Naked mole-rats evolved to thrive in an acidic environment that other mammals, including humans, would find intolerable. Researchers at the University of Illinois at Chicago report new findings as to how these rodents have adapted to this environment. The study was published online this week on PLOS ONE. In the tightly crowded burrows of the African naked mole-rats' world, carbon dioxide builds up to levels that would be toxic for other mammals, and the air becomes highly acidic. These animals freely tolerate these unpleasant conditions, says Thomas Park, professor ...

Women Have Options When It Comes To Hair Loss Thanks to Dr. Andrea Purcell

2012-09-22
Hair; for many women it is a defining factor of their looks. We spend hours washing, combing, styling, cutting, dying, and working it every which way to get the look we want. It is a source of expression and feminine pride and it is something that is uniquely ours. Unfortunately for many women, hair loss is a common and upsetting issue. Watching something so special and unique fall out before your very eyes can be painful and can hurt a woman's self-esteem and confidence. This loss of confidence can lead to other issues such as depression and anxiety. As a women ...
