New Urine Test May Replace Drawing Blood
New research from scientists at Clemson University in South Carolina shows how a newly developed urine test may lessen the need to draw blood to diagnose certain conditions. The research, published in the journal Proteomics - Clinical Applications, suggests that trace amounts of protein byproducts of diseases and drugs can be detected in urine, which can lead to the diagnosis of several diseases.
The team explains that at the center of the new test is material called “capillary-channeled polymer fiber” or C-CP fiber that helps to extract the proteins in an efficient way prior to screening. Currently, it is not easy to find these proteins because of the high amount of salt in urine.
To conduct their study, the researchers packed the C-CP fibers into plastic tubes and then passed urine samples through them in a centrifuge spinning for 30 seconds. From here, they conducted a process to extract the purified proteins from the C-CP fibers, finishing with 12 samples. The whole process took around five minutes.
Another researcher commenting on the study notes that the development of this new test is a significant breakthrough because urine is a better biomarker source than blood in detecting early onset diseases.

Vegan Diet May Reduce Diabetes Nerve Pain
A team of researchers suggests that following a plant-based, vegan diet may be as effective as medication for treating diabetic neuropathy, or nerve pain, which is often caused by uncontrolled blood glucose levels.
To conduct their study, the scientists put 17 overweight adults with diabetic neuropathy on a 20-week low-fat diet that emphasized fresh vegetables and high-fiber, complex carbohydrates such as beans and whole grains. The participants also attended weekly nutrition classes and took a vitamin B12 supplement, a nutrient that is important for proper nerve function, but found naturally only in animal products.
Results showed that compared with the control group of 17 adults who received B12 supplements but maintained their current, non-vegan diet, the group on the plant-based diet reported significant improvements in pain relief. Tests also showed improved circulation and nerve function. Plus, these study participants lost, on average, 14 pounds.
The researchers believe that this diet worked by allowing the body time to fix its nerve damage through increased insulin sensitivity and improved blood sugar levels. The team notes, though, that the new study was limited in that they could not determine which element of the low-fat, plant-based diet led to the improvements. For instance, it could have been the weight loss alone that was the key factor in neuropathy pain reduction.
