Bioengineering to prevent iron deficiency?
...le iron due to high phytate content could also be solved by introducing genes which increase the activity of phytase enzymes to break down the phytate. The authors conclude by calling for more data on the functional consequences of iron deficiency, eg. on immune function and cognition in infants and chil...Researchers find vitamin B1 deficiency key to vascular problems for diabetic patients

In conventional PET scans, patients receive a dose of short-lived radioactive material that emits positrons. The PET scanner then detects the photons released when the positrons c...Mid Sweden University leads development of digital color x-rays
