The concern is that contrast contains minute amounts of free iodide and as such, IV administration of this material puts the patient at risk of a life-threatening anaphylactic reaction. Contrast is often given in these tests as it traces out bloodflow enabling the physician to see organ and mass architecture much more clearly allowing for improved accuracy in seeing anything abnormal. Well… rest assured that patients with iodine and seafood allergy CAN receive contrast without any significant increased risk of an allergic reaction as compared to other allergies. In a large study en...

But she did have some advice to offer—and she emphasized that the connection between food and migraine is a very individual one. Several foods have been associated with triggering migraine. None of them has been scientifically proven to cause migraines, explained Allonen, but many people report a link between eating these foods and getting a migraine. Possible migraine triggers include: (more…) *This blog post was originally published at Harvard Health Blog* (Source: Be...

Conservation conversation – Improving storage and exposure conditions in conservation of artefacts is crucial to suppressing the fading and degradation of dyes and other components of paintings. Researchers have now used several analytical techniques, including attenuated total reflectance infrared spectroscopy, Raman spectroscopy, reflectance UV-Vis spectroscopy, X-ray fluorescence spectroscopy and optical microscopy, to investigate different conditions on common ...

A relatively benign dye, Lawsone, stains the skin (or hair) a ruddy brown. Like a semi-temporary tattoo. However, you're limited to pretty much just that color.

Researchers report in an American Cancer Society publication that reducing exposure to such compounds could prevent many women from developing the disease. Family history and genetic make-up are responsible for only a small percentage of breast cancer cases. Environmental and lifestyle factors, such as diet, are most likely involved in the majority of cases, say experts.These finding are too incomplete to make widespread conclusions, but still, they are considered "the most comprehensive compilation to date of chemicals identified as mammary carcinogens" and are so convincing t...
