How 3-D bioprinting could address the shortage of organ donations

2015-03-11
(Press-News.org) Three-dimensional bioprinting has come a long way since its early days when a bioengineer replaced the ink in his desktop printer with living cells. Scientists have since successfully printed small patches of tissue. Could it someday allow us to custom-print human organs for patients in need of transplants? An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, explores the possibility.

Matt Davenport, an associate editor at C&EN, points out that for every organ donor in 2012, there were more than eight patients on a waiting list. The ability to print functioning organs could completely transform the equation. But this goal is decades away and some scientists are unconvinced that bioprinting will ever replicate human organs.

Researchers still have many obstacles to overcome, such as how to incorporate blood vessels into printed organs. Vessels are critical for transporting nutrients and oxygen to cells, but they're also very complex. But as researchers confront these challenges, some experts predict that the new parts might work even better than the originals.

New mothers more satisfied after giving birth in a public hospital

2015-03-11
Women who give birth in a public hospital are more confident parents compared to women who have babies privately, a new Australian study has found. A joint study by Queensland University of Technology and the University of Queensland, surveyed more than 6400 mums in Queensland, and found women who birth in the public sector were more likely to receive after-hospital health care, in turn boosting their confidence as a new parent, than women in the private system. Associate Professor Yvette Miller from QUT's Faculty of Health and one of the authors of the study published ...

Cochrane Review of effectiveness of point of care diagnostics for schistosomiasis

2015-03-11
Researchers from the Cochrane Infectious Disease Group, hosted at LSTM, have conducted an independent review to assess how well point of care tests detect Schistosoma infections in people living in endemic regions. Schistosomiasis, also known as bilharzia, is a parasitic disease classified as a neglected tropical diseases (NTD), which is common in tropical and subtropical regions. The traditional means of testing for the disease is microscopy, which is lab based. Point-of-care tests and urine reagent tests are quicker and easier to use than microscopy in the field, and ...

TRMM sees large and more powerful Cyclone Pam, warnings posted

TRMM sees large and more powerful Cyclone Pam, warnings posted
2015-03-11
The Tropical Rainfall Measuring Mission or TRMM satellite saw powerful towering thunderstorms in Tropical Cyclone Pam, indicating the storm was strengthening as it moved through the Solomon Islands. Pam has now triggered warnings in the Solomon Islands, Vanuatu and New Zealand. In the Solomon Islands, a tropical cyclone warning was in effect today, March 11, for Temotu, Malaita and Makira provinces. A tropical cyclone watch was in effect for Rennell and Bellona, Central, Isabel, Western, Guadalcanal and the Choiseul provinces. In Vanuatu, a tropical cyclone warning ...

Finding strengths -- and weaknesses -- in hepatitis C's armor

2015-03-11
Using a specially selected library of different hepatitis C viruses, a team of researchers led by Johns Hopkins scientists has identified tiny differences in the pathogens' outer shell proteins that underpin their resistance to antibodies. The findings, reported in the January 2015 issue of the Journal of Clinical Investigation, suggest a reason why some patients' immune systems can't fend off hepatitis C infections, and they reveal distinct challenges for those trying to craft a successful vaccine to prevent them. Due to concerns about the rising costs of newly available ...

Researchers develop 'visual Turing test'

2015-03-11
PROVIDENCE, R.I. [Brown University] -- Researchers from Brown and Johns Hopkins universities have come up with a new way to evaluate how well computers can divine information from images. The team describes its new system as a "visual Turing test," after the legendary computer scientist Alan Turing's test of the extent to which computers display human-like intelligence. "There have been some impressive advances in computer vision in recent years," said Stuart Geman, the James Manning Professor of Applied Mathematics at Brown. "We felt that it might be time to raise the ...

Study explains control of cell metabolism in patient response to breast cancer drugs

2015-03-11
La Jolla, Calif., March 9, 2015 - Researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) have discovered a mechanism that explains why some breast cancer tumors respond to specific chemotherapies and others do not. The findings highlight the level of glutamine, an essential nutrient for cancer development, as a determinant of breast cancer response to select anticancer therapies, and identify a marker associated with glutamine uptake, for potential prognosis and stratification of breast cancer therapy. "Our study indicates that a protein called RNF5 ...

Naproxen plus acid-blocking drug shows promise in preventing bladder cancer

2015-03-11
ANN ARBOR, Mich. -- The anti-inflammatory class of drugs NSAIDs have shown great promise in preventing cancers including colon, esophagus and skin. However, they can increase the risks of heart attacks, ulcers and rare but potentially life-threatening bleeds. A new study suggests there may be ways to reduce these dangerous side effects. Collaborators from the University of Michigan, the National Cancer Institute and the University of Alabama looked at naproxen, which is known to have a lower cardiovascular risk than other NSAIDs. Naproxen, like most NSAIDs and aspirin, ...

Deadly to cancer cells only

2015-03-11
Parvoviruses are a class of viruses that normally infect rodents; in humans, they do not cause any disease symptoms. However, they are able to infect and kill cancer cells. The details behind this biological selectivity on the part of the viruses have not been understood until now. "Since the viruses might soon play a role in cancer medicine, it is important to know why they replicate exclusively in tumor cells in humans," says virologist Dr. Jürg Nüesch from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ). In order to complete their ...

New genetic evidence resolves origins of modern Japanese

2015-03-11
Was there a single migration event or gradual mixing of cultures that gave rise to modern Japanese? According to current theory, about 2,000-3,000 years ago, two populations, the hunter-gatherer Jomon from the Japanese archipelago, and the agricultural Yayoi from continental East Asia, intermingled to give rise to the modern Japanese population. However, some researchers have suggested otherwise, with the Jomon culture gradually transformed into the Yayoi culture without large migrations into modern day Japan. To resolve the controversy, researchers Oota, Mano, Nakagome ...

Stem cells in the brain: Limited self-renewal

2015-03-11
The generation of neurons (neurogenesis) in humans is predominantly limited to development; in the adult stage it takes place in only a few regions of the brain. These regions contain neural stem cells that generate neurons in a process with various intermediary stages. Stem cell renewal is limited - total number drops Until now it was thought that maintaining the stem cell pool was based on the self-renewal of individual stem cells. The team of scientists headed by Dr. Jovica Ninkovic and Professor Dr. Magdalena Götz were able to refute this: Both the self-renewal ...
