A major study examining the fish-eating habits of pregnant women has found that they are not linked to autism or autistic traits in their children. Scientists at the University of Bristol looked at the assumption that mercury exposure during pregnancy is a major cause of autism using evidence from nearly 4,500 women who took part in the Children of the '90s study.
Researchers have developed a new tool that utilizes basic laboratory tests to effectively identify patients with chronic obstructive pulmonary disease who are at high risk of being hospitalized due to a flare up of the condition.
An international team has discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets.
Researchers in Bochum have deployed a novel infrared (IR) microscope with quantum cascade lasers in order to analyze tissue samples taken during routine clinical procedures for colorectal cancer diagnosis. The IR microscope used to date had not yet established itself as a diagnostic tool in hospitals, as the analyses used to take too long. By utilizing the new laser technology, the researchers reduced the time required for analysis from one day to a few minutes.
This vision of simplifying disease diagnosis using topically applied nanotechnology could change the way skin diseases such as abnormal scars are diagnosed and managed.
UC San Diego researchers have developed a test that can screen for pancreatic cancer in just a drop of blood. The test, which is at the proof-of-concept stage, provides results in under an hour. It's simple: apply a drop of blood on a small electronic chip, turn the current on, wait several minutes, add fluorescent labels and look at the results under a microscope. If a blood sample tests positive for pancreatic cancer, bright fluorescent circles will appear.
New research has uncovered a surprise link between a common bacterial toxin found in the gut and inflammatory bowel disease (IBD).
There is a continuing need for practical chip-based sensors that can be used at the point of care to detect cancer and other diseases. An innovative way to inject light into tiny silicon microdisks could help meet this need by bringing down the cost and improving the performance of chip-based biosensors.
For women, mammograms are a sometimes uncomfortable, but necessary, annual ritual. But this procedure doesn't always provide accurate results, and it exposes women to X-rays. In a study appearing in ACS' journal Molecular Pharmaceutics, scientists report that they have developed a non-invasive 'disease screening pill' that can make cancerous tumors light up when exposed to near-infrared light in mice without using radiation.
The team of researchers at Kaunas University of Technology, Lithuania are developing mathematical methods which could help diagnose breast cancer. Applying deep learning method, the researchers are aiming to 'teach' computers to recognize malignant lesions, which would allow at least partially automatize and enhance the accuracy of diagnosing breast cancer.
